Health care innovation, notably in clinical neurology and neurophysiology, has been rapidly growing over the last few decades, both in terms of therapy and diagnosis. Hence, it is necessary to spread and share information along the various possible paths. In this time of confinement, and to keep abreast of current news, mainly in the developing regions of the world, the Moroccan Society of Neurophysiology IFCN Chapter and the Moroccan League Against Epilepsy ILAE Chapter organized a series of Expert Webinars over three months (May, June, and July 2020) and focused on topics of concern to the clinicians in their daily practice, particularly in the field of clinical neurology and neurophysiology (EEG, EMG, EP, IONM, PSG, TMS, Epilepsy, Neuromuscular diseases, Sleep, Neurostimulation, etc.). The webinar language can be English or French, and many renowned experts in the different fields of clinical neurology and neurophysiology kindly accepted our invitation.

This innovative initiative aims to animate the field of clinical neurology/neurophysiology in our context and boost synergies between the players in various medical and surgical disciplines involved in neurology. Highly supported by the scientific community, the Clinical Neurophysiology Expert Webinars discussed the daily challenges faced by practitioners in teaching clinical cases.

Example of a full Q&A session after Prof. Kaji’s talk.

These webinars had the following objectives: ensuring the continuity of the teaching of young people and the continuing education of specialists and practitioners, substituting for the scientific days, meetings, congresses, and training courses usually organized at this time of the year, perpetuating solidarity and collaboration between national and international professionals, and reinforcing the relationships between the SMNPH, IFCN, and WFN. Finally, another objective is to unify the efforts of scientific societies to address the multiple global health challenges caused by the various pandemic threats to humanity, such as the COVID-19 pandemic.

This initiative was inaugurated with an EEG and epilepsy course led by Prof. Ron Lesser focusing on EEG interpretation, including normal EEG interpretation (techniques, artifacts, and normal aspects) and pathological EEG interpretation (epileptic abnormalities and non-epileptic abnormalities), and Prof. Gregory Krauss, who presented a lecture on nonepileptic events often misidentified as seizures (psychogenic seizures and syncope).

The second session of lectures, dedicated to EMG and neuromuscular diseases, took place the next day. Prof. Henry Kaminski from George Washington University talked about the diagnosis and treatment of ocular myasthenia gravis. In addition, we were gratified by the participation of Prof. Ryuji Kaji (First Vice President, WFN, Japan), as our special invited speaker, who provided an update on the electrodiagnosis of ALS and related disorders.

The Moroccan Neurophysiology Society (MNPS) has been excited to receive the feedback from the participants who have enormously appreciated these new ways of scientific meetings and who keep asking for more webinars.

The program, which concluded July 30, included more than 40 presentations that were presented by a variety of expert speakers and moderators. •

 

 

History of Neurology: Treatment Evaluation Takes Time

A Cautionary Tale From the History of Malaria Fever Therapy

By Aernoud T.L. Fiolet and Ingrid M. Daey Ouwens

 

Introduction

History is the present seen through the eyes of the future. Now, more than ever, we are confronted with this aphorism, as one of the most impressive contemporary pandemics unrolls. As of mid-October 2020, according to the WHO (https://www.who.int/emergencies/diseases/novel-coronavirus-2019), more than 39 million cases have been confirmed worldwide, including more than 1 million deaths. The societal and economic sequelae of the virus management are felt on a global scale. Meanwhile, scientific research on the subject has surged. Fundamental research quickly provided insight on the virus genome and its systemic dissemination.1 Many institutions and pharmaceutical industries have reallocated resources on the development of therapeutic solutions. The focus is on effective vaccination, strategies to reduce the hyperinflammatory response, and support of the critically ill.2,3 While attempting to catalyze the process of resolving current unmet needs, the risks of compromising scientific integrity and validity may become apparent.4

A chart of a patient with General Paralysis of the Insane, dated 1954. The points and connecting curves depict the three-day cycle of recurrent fever after inoculation with Plasmodium vivax, paralleled by an increase in heart rate.

The history of medicine teaches us that the elusive nature of a disease and the urgency felt by the medical society to treat it may incite as well as impede scientific development. An example par excellence is the intentional inoculation with plasmodium, the causative agent of malaria, to induce fever in patients suffering from General Paralysis of the Insane. In the early 20th century General Paralysis of the Insane was a much feared and nearly always lethal presentation of syphilitic infection. Future Nobel prize laureate Julius Wagner-Jauregg evoked a paradigm shift for the treatment of this condition when he developed malaria fever therapy.5

This paper on the introduction of malaria fever therapy for General Paralysis of the Insane aims to provide a meaningful insight into pitfalls that may arise during scientific developments in urgent times, then and now.

General Paralysis of the Insane and Malaria Fever Therapy

General Paralysis of the Insane, also designated “General Paralysis” or “dementia paralytica,” caused a worldwide health care problem with a considerable social and economic impact during the turn of the 19th to 20th century. At its peak, one-fifth of admissions and one-third of deaths in asylums in western Europe and the United States were attributable to General Paralysis of the Insane.6 In this tertiary form of syphilis, progressive neurological and psychiatric symptoms occurred six months to several decades after the initial syphilitic infection. Most patients died within six years after diagnosis. Various applications of highly toxic heavy metals, e.g. mercury, sulphuric acid, and arsenic acid, were used to treat early stages of syphilis, mostly with some success. As with all manifestations of syphilis, long-term treatment was required, hence the expression, “One night in the arms of Venus leads to a life on Mercury.” However, these methods were of limited use in General Paralysis of the Insane.7

Beneficial effects of fever due to an intercurrent disease in patients with somatic and psychiatric conditions have been reported since classical times.8 The Austrian psychiatrist Julius Wagner-Jauregg (1857-1940) took this approach one step further by intentionally inducing fever in psychiatric patients.8,5 At the end of the 19th century, he started his experimental treatments using streptococci, tuberculin, and typhoid vaccine. The results, however, were disappointing. He continued this line of research more than a decade later. In 1917, he induced fever by inoculation of blood containing plasmodium. The ensuing malarial fever spikes were terminated with quinine bisulphate. In addition, the patients received neosalvarsan, an arsenic, to treat their syphilitic infection. This treatment, referred to as malaria fever therapy, was adopted as the standard treatment for General Paralysis of the Insane by the global scientific community within 10 years of Wagner-Jauregg’s first report.9

Contemporary Scientific Report on Malaria Fever Therapy

Wagner-Jauregg’s first report comprised a case series of 10 malaria-inoculated patients with General Paralysis of the Insane. Nine of these patients contracted malaria. Following this treatment, two patients showed permanent considerable improvement with regard to General Paralysis of the Insane, four patients suffered relapses, two had to be sent to an asylum, and one patient died.5

Gerstmann, at the time an assistant at Wagner-Jauregg’s clinic, reported that at the end of 1921 more than 200 patients had been treated with malaria fever therapy in their clinic, of whom 50 had been able to return to work. These results encouraged the introduction of malaria fever therapy not only in Europe, but also in South America and the USA. In 1926, an international review of 2,460 cases recorded in the literature found that 27.5% of the treated patients improved greatly and another 25.6% moderately in accordance with the findings of Gerstmann.10 In 1927, Wagner-Jauregg was awarded the Nobel Prize in Physiology or Medicine “for his discovery of the therapeutic value of anti-malaria vaccination in the treatment of dementia paralytica.” This recognition undoubtedly contributed at an international level to an increase in the number of malaria fever treatments applied. Within 10 years of Wagner-Jauregg’s first report, malaria fever therapy was globally adopted as the standard treatment for General Paralysis of the Insane.9

Current Appraisal of Malaria Fever Therapy

The reported treatment outcome appeared very favorable for a previously considered untreatable condition. However, the evidence to support the efficacy of malaria fever therapy was weak. It is remarkable that in 1933 malaria fever therapy was not yet subjected to a standardized set of regulatory research criteria, while at that time any drug used in the treatment of patients was controlled with formal standards including animal research, toxicity tests, histopathological studies, tests of therapeutic efficacy, and approval by a federal regulatory board.9 Only observational studies were available with many differences in often poorly described patient characteristics and diagnostic criteria. By 1924, malaria fever therapy was also used in asymptomatic individuals who had a positive Wassermann reaction (indicating syphilitic infection), in order to prevent the development of late stage General Paralysis of the Insane.8,9 The number of patients included is often not clarified. Differences in malarial strains used, the mode of infecting the patient (inoculation of malaria-infected blood versus the bite of infected mosquitoes), number of fever spikes left untreated, pharmacological treatments preceding or following malaria fever therapy, and outcome criteria will all have influenced the results.9 Moreover, differentiation between treatment outcome and spontaneous remission requires a long follow-up period of at least three years, much longer than the usual follow-up period reported in the studies.

Perhaps most importantly, it was not possible to isolate the effect of the induced fever in itself from the effect of concomitant heavy metal therapy and general hygiene strategies taken to improve the patient’s general health. Fresh air, good nutrition, massage, hydrotherapy, and the elimination of physical and mental stress were implemented in the hope of increasing the bodily defense against the syphilitic infection and to strengthen the condition of the patients prior to the exhausting effects of malaria fever therapy.7,9

Lastly, reporting bias may have led to a distortion of the published results. Wagner-Jauregg and Gerstmann did not report the death of three out of four newly inoculated patients with General Paralysis of the Insane in 1917 or 1918. Due to Wagner-Jauregg’s omission to microscopically examine blood prior to inoculation, these patients had received blood containing plasmodium vivax. As he later documented in his memoirs, these patients consequently had contracted malaria tropica, a malignant form of malaria.5 p136 When he resumed his “vaccination” trials later in 1920, Wagner-Jauregg only used blood taken from cases of confirmed tertian malaria. Risks associated with malaria fever treatment were considerable, with reported mortality rates varying from 4% to 20%.7 The relatively high morbidity and mortality rates concomitant with this severe form of treatment seem to have received initially a mostly perfunctory discussion, probably as a result of the general feeling of hopelessness in patients and physicians with regard to General Paralysis of the Insane. As Moore, professor of Medicine at The Johns Hopkins University, whose whole professional career was devoted to the study and treatment of syphilis, put it: “desperate situations usually justify desperate risks”.9

In conclusion: the history of malaria fever therapy teaches us that a compelling need to contribute to the solution of a global health problem may compromise critical appraisal; in this example the situation led to the introduction of a globally applied and Nobel Prize-awarded treatment of uncertain benefit. Therefore, even in the midst of a pandemic, it is necessary to find the right balance between the rapid availability of therapeutic and preventive measures on the one hand, and careful research and ethical considerations on the other. •

Lessons Learned From Janakpuri Super Speciality Hospital Society in New Delhi, India

By Dr. Man Mohan Mehndiratta, Dr. Amrita Tiwary Vyas, Dr. Natasha Singh Gulati, Dr. Yogesh Sharma, and Durgesh Kumar Pathak

We would like to walk you through the seven steps we recommend for conducting a virtual public awareness event. This has really helped us to get our message out to the community on World Brain Day 2020 with a live event held at Janakpuri Super Speciality Hospital Society in New Delhi (JSSHS), India.

Step 1:  A Well-Thought-Out Theme With a Bird’s Eye View

Prof. Man Mohan Mehndiratta, director, professor, and head of Neurology, JSSHS, decided to take the responsibility of sharing the efforts of the WFN on World Brain Day, following the theme of moving together to end Parkinson’s disease.

Despite the constraints of the COVID-19 Pandemic and social distancing, a virtual public awareness and education series was planned and held July 22, 2020, at JSSHS with the above theme.

Step 2: Choosing Speakers and Inviting Them

Eminent international and national neurologists were invited as speakers. Telephonic and email correspondence occurred, requesting them to spare their time for their valuable input as panelists for this event.

Step 3: Informing Patients and Their Caregivers

Parkinson’s disease patients and caregivers who had visited the neurology outpatient department in the previous few months were registered with their contact details and were continuously informed regarding event plan updates.

Step 4: Engaging the Administration for Telecommunication Setup and Creating Video Links

Step 5: An event schedule page.

High speed internet connectivity, audio visual setup, and virtual platform video links were tested, along with a pre-event dry run to ensure smooth functioning of the event.

Step 5: Creating An Event Schedule Page, Informing the Speakers and Audience, and Cross-Promoting

Step 6: Encouraging Interaction and Participation And Keeping the Event Interesting

All of the patients were given a chance to ask their queries. An e-poster competition was also held with e-certificates and cash prizes. The results were announced the very same day with the judges being the invited faculty speakers

Step 7: Finally, Evaluating the Event And Continuing to Engage In or Arrange Similar Events In Future Years

We hope these seven steps are helpful to others as they plan future events promoting awareness of neurological disorders. •

World Brain Day Celebration in India

by Chandrashekhar Meshram, Pramod Kumar Pal, Gagandeep Singh, Nirmal Surya, Vinay Goyal

The theme of this year’s World Brain Day, “move together to end Parkinson’s disease,” is very relevant for patients, their caregivers, family physicians, and the general public, and therefore there was a lot of excitement about the event. World Brain Day was cerebrated throughout India on July 22. Due to the COVID-19 pandemic, auditorium or field programs could not be organized, so the campaign was mainly through print and electronic media with virtual meetings in different cities of the country.

Mumbai

A World Brain Day awareness program was organized as a webinar by the Indian Academy of Neurology (IAN) and the Epilepsy Foundation and Movement Disorder Society of India (MDSI). The secretary of IAN, Dr. Gagandeep Singh, made introductory remarks and introduced the faculty for the event. Dr. Tissa Wijeratne, chair of World Brain Day, inaugurated the event by lighting a lamp. He also mentioned that though Parkinson’s disease was first described in modern literature by James Parkinson, ancient Indian physician Sushruta had mentioned it as Kampa Vata a few thousand years back and suggested treatment for it. He said there is a lack of awareness about this disease even in developed countries, so this theme was chosen.

Dr. Pramod Kumar Pal, president of IAN and a movement disorder specialist, mentioned that there are many young Parkinson’s patients in India and there is a need of epidemiological study of Parkinson’s disease. Dr. Vinay Goyal, president of MDSI, said that the major problem is delay in diagnosis due to lack of awareness about this disease. Dr. U Meenakshi Sundaram, secretary of MDSI, presented interesting statistics about Parkinson’s disease. Dr. Chandrashekhar Meshram, convener of National Brain Week and World Brain Day, stressed the importance and ways of celebrating WBD. Dr. Nirmal Surya, chairman of the Epilepsy Foundation and treasurer of IAN, who took initiative to organize this event, made the closing remarks and answered questions. Dr. Nirmal Surya also posted a video on the WFN website.

Nagpur

Dr. Chandrashekhar Meshram issued the press release. Information about Parkinson’s disease appeared in nine newspapers. The awareness program was organized by Indian Academy of Neurology, Nagpur Neuro Society, Nagpur Psychiatry Society, Orange City Cultural Foundation, and Saptak as a webinar on July 22. The event was inaugurated by Dr. Lokendra Singh, president of the Neurological Society of India. Dr. Meshram explained clinical manifestations of Parkinson’s disease through videos. Neurologist Dr. Dhruv Batra explained available treatment options for better day-to-day activities. Psychiatrist Dr. Sudhir Bhave highlighted various psychological problems in patients with Parkinson’s disease and how to cope with them. Jayashree Pendharkar explained the role of proper diet in these patients. Dr. Sheetal Mundhada showed various exercises for these patients through a video demonstration and emphasized the role of yoga, physiotherapy, and various exercises for a better life. Dr. Nitin Chandak answered questions from the audience. Dr. Kajal Mitra, dean of NKP Salve Institute of Medical Sciences, announced that the chairperson of the Institute, Ranjeet Deshmukh, will sponsor one deserving patient every year for deep brain stimulation (DBS). About 500 people attended the webinar.

Move Together to End Parkinson’s Disease: World Brain Day 2020 in Pakistan

By Dr. Abdul Malik- MD

The World Federation of Neurology (WFN) promotes brain health through its education, skills development, and advocacy activities. Since 2014, the WFN has organized dedicated awareness drives in all the WFN member countries around the globe.

Abdul Malik

The WFN, in collaboration with the International Parkinson’s and Movement Disorder Society, declared the sixth World Brain Day this year, dedicated to the awareness for Parkinson’s disease, which is a neurodegenerative brain disease that affects the mind, movement, and almost all aspects of brain function.

We in Pakistan, along with numerous other global organizations, joined again this year with this campaign to support the WFN in advocating for improved patient care, education, and additional research for those living with Parkinson’s disease and their caregivers.

The Neurology Awareness and Research Foundation (NARF) organized countrywide activities to mark the sixth World Brain Day, with the theme of moving together to end Parkinson’s disease. Parkinson’s disease affects people of all ages, including one in 100 people over the age of 60. The prevalence of this disease is on the rise, making our actions today vital to improving the lives of those who have been and will be diagnosed, particularly during this global health crisis.

Keeping in view the COVID-19 pandemic, our organized activities in Pakistan (online through Zoom and Facebook) became regional and even global activities as our participants were just not from Pakistan; they were from India, Bangladesh, the UAE, the U.S., the U.K., Canada, and different other parts of the Europe.

These awareness activities were more focused on social media like Twitter, Facebook, and WhatsApp. We also organized patient welfare activities by organizing two free Parkinson’s clinics on July 19 and July 24, adopting all standard operating procedures regarding the patients’ and medical staff’s safety. The services provided during these free clinics included not only free consultation from a neurologist, but also free services from a physiotherapist, speech therapist, and neuropsychologist.

We prepared awareness flyers in the Urdu language about Parkinson’s for the general public; this material was in simple, pictorial form about the signs, symptoms, treatment, and rehabilitative awareness of Parkinson’s disease and was distributed in 500 clinics across the country. Month-long Facebook as well as Twitter activities were executed with key messages given by the WFN and translated into the local language. World Brain Day posters were placed in almost all of the major institutes and departments of neurology in Pakistan.

We prepared a NARF Exercise Diary in the Urdu language with illustrative pictures to inform Parkinson’s patients about the importance of exercise as well as to motivate them to do these exercises at home. The diary comprises exercises involving all four limbs and trunk, including standing and sitting postures with facial exercises; speech exercise and speech therapy are also briefly described. This diary was launched in collaboration with the Pakistan Parkinson’s Society and was distributed among all neurology centers throughout Pakistan.

On July 14, NARF organized a Facebook Live public awareness session on Parkinson’s disease in the context of WBD 2020. This session was held at Aga Khan University in Karachi and was organized with the leading media group of Pakistan, Duniya. The complete proceedings of this session were published in the Daily Duniya newspaper. In this session, we had the top neurologists of the country, Prof. M. Wasay, Prof. Naila Shahbaz, and Dr. Bashir Soomro, as the participants. Besides these we had the director of the Institute of Psychology, Prof. Dr. Uzma Ali; an assistant professor and physiatrist from the Institute of Physical Medicine and Rehabilitation of DUHS, Dr. Syed Saeed Qaiser; and the editor of the Daily Duniya Karachi, Ahmed Hasan, as the panelists. Dr. Abdul Malik and Mustafa Habib Siddiqui were the moderators of this extensive awareness session, which was seen live in almost two dozen countries.

On July 22, NARF organized a Zoom webinar which was CME-accredited by the Jinnah Sindh Medical University. Principal Liaquat College of Medicine and Dentistry Prof. Dr. Rashid Naseem Khan gave opening remarks. The educational talk in context of the theme of World Brain Day was given by Dr. Abdul Malik, the rehabilitative talk was given by Dr. Farooq Rathore, and the keynote speech on the review of non-motor symptoms with recent advances in Parkinson’s management was given from Canada by the Dr. Abdul Qayyum Rana. A large number of undergraduate students, postgraduate trainees, and faculty members attended this interactive academic session.

The awareness activities were not only covered in national and local newspapers but also in the electronic media. Almost a half dozen leading newspapers and magazines published articles on Parkinson’s disease.

In short, keeping in view the COVID-19 pandemic, a comprehensive advocacy campaign for Parkinson’s disease awareness was executed on the occasion of this year’s World Brain Day 2020 from Pakistan as a member of the WFN. •

John D. England, MD

The COVID-19 pandemic has disrupted almost everything, including international meetings. ICNMD 2020, which was scheduled to take place in Valencia, Spain, in July 2020, was cancelled because of global travel restrictions.

The unprecedented situation necessitated the development of new strategies for holding the meeting. The ICNMD team decided to provide a virtual (digital), brief, topic-focused update on neuromuscular diseases for 2020. Since many new diagnostic and therapeutic options are increasingly available, an interim update was deemed to be important. Specific examples for which new therapies are available include spinal muscular atrophy (SMA), hereditary ATTR (hATTR), amyloidosis, and myasthenia gravis. Many additional therapies are in various stages of development.

The challenge was to organize and dedicate speakers who could present time-sensitive information on myopathies, neuropathies, neuromuscular transmission, and motor neuron disease, as well as satisfy the requirements of an EACCME-accredited meeting. Time also was dedicated for excellent industry-sponsored presentations, similar to satellite symposia in face-to-face meetings.

With the help of professionals from International Conference Services Ltd, the development and fulfillment of ICNMDigital 2020 went extremely well. ICNMDigital achieved an impressive attendance of over 796 delegates from more than 58 countries. The program featured 27 speakers in 12 scientific sessions across four thematic days. In addition, several Industry-Supported Symposia were presented. Feedback from attendees was very positive, and most participants suggested that some form of virtual presentations remain a part of future meetings.

As validation of the sucess of the conference, we offer the following comments from participants:

“We hope that 2021 will give us the possibility to organize the live congress again in Valencia, and definitely we have learned that virtual sessions and hybrid constructions will be useful and necessary in the future.”

“ICNMDigital met the challenge to organize in a very short time frame an exciting congress with outstanding content. The technical staff was incredibly helpful to make it a successful and smooth experience. Two thumbs up for organizers and all people with hands on!” –Laurent Servais

“I was fortunate to be able to give a talk alongside Mary Reilly, one of the best inherited neuropathy researchers in the world. Her talk brought a great crowd and set us on the right track. Davide Pareyson was a wonderful moderator, and we had incredible questions from the audience. The virtual format worked well, and I think encouraged even more thoughtful questions, which is what helps everyone learn. The ICNMD conference pulled off a great conference given very difficult circumstances.” – Brian Callaghan

As a reminder, the live ICNMD 2021 meeting is scheduled for May 28-June 1, 2021 in Valencia, Spain. Faculty from ICNMDigital 2020 will again join with the addition of new experts/sessions addressing updates and breakthroughs in research. A special session on COVID-19 is planned. All previously accepted abstracts remain on the schedule for ICNMD 2021. In addition, the ICNMD 2021 website will reopen for new or updated abstract submissions.

Parkinson’s Disease in Africa: A South African Perspective

A Report in Relation to World Brain Day 2020

By Dr. Marcelle Smith and Dr. Patty Francis

The African continent has been experiencing rapid changes in recent decades, with increases in life expectancy. The average healthy life expectancy increased from 46.1 years in 1990 to 55.2 in 2017.1 This is still far below the average life expectancy in high-income countries of over 70 years.2 However, this has been sufficient to increase the burden of age-related and neurodegenerative conditions such as Parkinson’s Disease (PD).

Marcelle Smith, Patty Francis

There is a belief that PD is less prevalent in African countries, but incidence or prevalence studies for Africa are lacking. Most of the available studies are specific to individual countries. Williams et al. reviewed all the literature on PD in Sub-Saharan Africa published up to May 2016. The authors observed a prevalence of PD ranging from 7/100,000 in Ethiopia to 67/100,000 in Nigeria.3

African countries experience unique challenges when it comes to diagnosis and treatment of PD. Firstly, there are far fewer neurologists in African countries compared to high-income countries, 0.03/100 000 in Africa versus 4.84/100,000 in Europe as per the WHO Neurology Atlas. The WHO recommends at least one neurologist per 100,000 people.4 Approximately 270 million Africans live in countries where there are less than five neurologists per country. Less than 50% of Sub-Saharan African countries have a neurological society.5 This limited access to neurologists leads to underdiagnosis and treatment of patients with neurological disorders such as PD.

The Neurology Association of South Africa comprises 87 neurologists in full-time private practice, 28 in full-time public sector practice and six members in limited practice. 27 registrars are currently in training. This gives a crude estimate of one neurology service provider per 400,000 population in South Africa.

Many African countries are also overburdened by malaria, TB, HIV, and other infectious outbreaks, e.g. Ebola. Hence very few facilities and resources are dedicated to non-communicable illnesses. Medication is only available to 12.5% of Africans with PD compared to 79% in Europe.5 60% of Africans live off less than $2 a day and are unable to afford the necessary treatment themselves.6

South Africa’s population was estimated at 59,308,690 people at mid-year 2020, according to UN data. Between 16-17% of these have private medical insurance, while the rest are dependent on state facilities for health care. Only three PD medications are available in state hospitals at present: levodopa, amantadine, and dopamine agonists. South Africa’s largest private medical funder’s formulary includes biperiden, pramipexole, amantadine, levodopa/decarboxylase inhibitor, and rasagiline.

It is estimated that over 160,000 patients with PD have had deep brain stimulation (DBS) surgery worldwide. This is increasing at a rate of approximately 12,000 per year.7 Three tertiary state neurological centers in South Africa are equipped to perform DBS but still struggle with funding for devices. Four private sector practices offer DBS, although these are general neurology practices with a special interest in movement disorders. No singular movement disorders center exists due to the absolute necessity to cover the entire spectrum of neurology given the ratio of neurologist to patients.

In a recent survey, 74% of South African neurologists report they have referred patients for DBS for the management of a movement disorder.8 Roughly, only one in four (27.37%) neurologists felt they had enough knowledge of, and experience with, the indications for referral for DBS.8 Most South African neurologists refer to the few available DBS centers for Parkinson’s Disease (61.05%).8 However, one of these centers reported performing only five procedures over the last five years. Adequate treatment may allow PD sufferers to continue working and providing for their families for longer.

Most PD sufferers present with the tremor predominant phenotype, which is most common in high-income countries as well. There are, however, certain clinical characteristics unique to African cohorts. In 2016, Mahne et al. from South Africa demonstrated that the akinetic-rigid variant is encountered more frequently in Black patients compared to white patients and can be found in up to a third of all patients.9 This result was replicated by Smith and Modi in a larger cohort. The authors further demonstrated that Black patients appear to develop PD symptoms at an earlier age and develop cognitive impairment more frequently than their American and European counterparts.10 A recent study out of Ethiopia by Melke et al. has also demonstrated a higher prevalence of Parkinson’s disease-related sleep disorders compared to high-income countries.11

African populations have greater levels of genetic diversity and population substructure compared to non-African populations. Africans have also developed many genetic adaptations that have evolved in response to factors such as diverse climates and exposure to infective diseases.12 This makes Africa a prime place to study genetic diversity and its impact on different diseases. In the last two decades, research of PD genetics in Sub-Saharan Africa has gained momentum. In 2009, Bardien et al. concluded that mutations in the Parkin gene, a common cause of genetic PD worldwide, were not an important cause of PD in South Africa.13 The G2019S mutation in the LRRK2 gene is the most common mutation associated with PD. However, a 2019 study from Du Toit et al, revealed that none of the 91 Black South African participants in their study had this mutation.14 This shows that some of the most common PD-associated genetic mutations globally are not truly relevant in Sub-Saharan African populations. The mutations specific to PD in this populations have yet to be discovered and hold much potential for further research.

The dearth of genetic studies in African countries can, like many other problems on the continent, be attributed to a scarcity of resources. An in-depth look into PD genetics may provide answers to whether characteristics specific to PD in African countries does in fact have a genetic and ethnic foundation, or if it is related to poverty and other challenges experienced by low-income and under-resourced populations.

The amount of PD research in African countries has increased significantly in the last two decades; however, the studies have not been directly comparable because of inconsistence among study designs.15 As African neurologists we need to strive for collaboration between different countries across the continent to find solutions to our continent’s unique challenges.

GBA mutations have emerged as the most common risk factor in PD.16 Some of the clinical features including early age of onset and cognitive impairment are also more common in patients of African origin compared to Caucasians. A genetic study investigating the prevalence of the GBA mutation in PD patients in Africa may yield interesting results.

Academic centers across Africa are collaborating more and more with one another as well as overseas centers through shared congresses and research. An example of this is the combined annual meeting of the Neurological Association of South Africa and the African Academy of Neurology in 2019. Collaboration is the key to improving care for our continent’s Parkinson’s disease population and to better understand the unique aspects of Parkinson’s disease in Africa. •

A Great Time at The Neuro

My Report of the Canadian Department Visit Program (2019)

by Guillermo Delgado-García, MD

A snowy Montréal received me on a Saturday in mid-November; the previous morning I sat my annual examination and then I was there—3,700 kilometers from Mexico City. After touring Montréal’s museums, Monday arrived and I visited Dr. Anne-Louise Lafontaine, chief of the Department of Neurology of the McGill University Health Centre at the Montreal General Hospital. Dr. Lafontaine was extremely kind, welcomed me warmly, and asked me about my plans for the observership and also for the future.

From left to right: The author, Dr. Eliane Kobayashi, program director of the Frederick Andermann Clinical & Research Fellowship in Epileptology & EEG, and Dr. Dina Namiranian, a senior neurology resident, at the EEG lab.

Back at The Neuro, I looked for Dr. Eliane Kobayashi (Fig. 1) and found her at the weekly epilepsy rounds, held at the EEG lab, where cases are presented and discussed by a world-renowned multidisciplinary epilepsy team, including epileptologists, neurosurgeons, and neuropsychologists, among other highly trained professionals. At the end of the rounds, I introduced myself to Dr. Kobayashi, and she received me with open arms from the beginning. I then joined her team at the Epilepsy Monitoring Unit (EMU). This team was awesome, very friendly, and included Dr. Ghada Abbas (epilepsy/EEG fellow), Dr. Austin Zaloum (neurology resident), and Dr. Rafael Batista João (visiting epileptologist from Unicamp). The EMU is a place specially designed and equipped to care for adult patients undergoing long-term video EEG and is currently considered the gold standard for the diagnosis of epilepsy and seizure-like spells (Epilepsia. 2018;59:27-36).

On Wednesday mornings, I attended McGill’s neurology grand rounds in the de Grandpré Communications Centre, and afterward I stayed there with the neurology residents for the academic half-day activities. One afternoon that first week, I joined Dr. Kobayashi at the outpatient clinic, and there I also met Dr. Giovanni Pellegrino (epilepsy/EEG fellow), with whom Dr. João and I discussed the differences in neurological and epilepsy training in different parts of the world.

On Thursday morning, I met my supervisor, Dr. Birgit Frauscher, at the EEG lab. She was extraordinarily kind, generous, and inclusive all along. From that moment on, I started interpreting routine and prolonged EEGs with her at the reading room. That very day, she introduced me to her wonderful and diverse team from the Analytical Neurophysiology (ANPHY) Lab: Dr. Véronique Latreille, Dr. Petr Klimeš, Dr. Laure Peter-Derex, and Tamir Avigdor. This lab seeks to employ a variety of quantifiable tools in order to shed light on neurophysiological and pathological processes (mainly sleep and epilepsy). In the ANPHY lab, I was also introduced to high density EEG and other advanced source localization techniques.

After one of Dr. Gotman’s lab meetings. In the background, the evocative mural The Advance of Neurology (1955) by Mary (Filer) Spence-Sales can be seen (room 124). From left to right: Abdullah Azeem, Natalja Zazubovits, Tamir Avigdor, Dr. Petr Klimeš, Dr. Birgit Frauscher, the author, Dr. Jean Gotman, Dr. Véronique Latreille, Dr. Willemiek Zweiphenning, Dr. Andreas Koupparis and Dr. Nicolás von Ellenrieder.

That weekend Dr. Frauscher invited me to the First National Training Course on Sleep Medicine, which she organized and chaired. This two-day program was designed to provide a basic working knowledge of sleep medicine for Canadian neurology residents, and included a range of internationally renowned speakers and hands-on practical training on case interpretations of polysomnography. This course allowed me to interact with neurology residents from different universities, as well as with Canadian sleep experts.

 

The next week, I joined Dr. Frauscher at the outpatient clinic, where she introduced me to the very practical basics of vagal nerve stimulation in epilepsy. Furthermore, she let me get involved in preparing the next stereo EEG planning meeting and this was, in fact, my first real-life exposure to stereo EEG. Meanwhile on the scientific side, on Friday afternoons we all attended Dr. Jean Gotman’s lab meetings, which were both challenging and appealing.

From that week on, I started attending The Neuro’s Killam Lectures, held on Tuesday afternoons, and also the weekly epilepsy conferences, held on Thursday afternoons. The Killam Lectures are supported by the Killam Trusts and are given by outstanding guest speakers whose research is of interest to the scientific community at The Neuro and McGill University. On the other hand, the epilepsy conferences included a case presentation, EEG review, and roundtable discussion.

In my third week, I worked with Dr. Frauscher and Dr. Zaloum at the EMU. It was an intense but also very rewarding week. In addition, I had the opportunity to attend the tribute to Dr. Frederick Andermann (1930-2019), where an international panel of renowned epileptologists gathered to present the latest advances in the field in an homage to Dr. Andermann, director of the epilepsy unit at The Neuro for 35 years and one of the world’s most distinguished epileptologists. This special event was both intellectually stimulating and moving. During the second half of my observership, I also had the honor to work under the supervision of Dr. Martin Veilleux at the EMU.

In addition to the impact of this observership on me in terms of clinical and scientific experience, I really want to highlight another aspect of my visit: the kindness and openness of all the people I met in The Neuro, as so perfectly exemplified by daily lab lunch with Dr. Frauscher and her team. Among those whom I have not mentioned by name above, Natalja Zazubovits and Abdullah Azeem from Dr. Gotman’s lab were eager to help all the time and their assistance was invaluable to me.

One morning there was an exception to my normal work week at The Neuro. On this occasion, I visited the Osler Library of the History of Medicine, a branch of the McGill University Library. This visit was only possible thanks to the immense generosity of Dr. Mary Yearl, the Osler librarian, since the Osler Library was temporarily closed due to a fire at the McIntyre Medical Sciences Building. Rare materials were rehoused in the McLennan Library Building and that was where Dr. Yearl patiently showed me the treasures and rarities of the Osler Library. She later took me to the Osler Room in the McIntyre Building and, even though it was empty, it was evident what Michael Bliss wrote in his book: the Osler Room was “a shrine, architecturally a cross between a church and a mausoleum.” (William Osler: A Life in Medicine, 1999)

Sir William Osler (1849-1919) has been one of my medical and intellectual role models for more than a decade, so this visit had a great impression on me. Although less and less read, many of his insights are still true for general neurology and even for epileptology. The following passage is an example of this: “It is well always to be suspicious of epilepsy developing in the adult, for in a majority of such cases the convulsions are due to a local lesion.” (The Principles and Practice of Medicine, 1892) When we said goodbye, Dr. Yearl told me that I could not leave Montréal without visiting Mont-Royal. Therefore, on my last day before returning to Mexico City, I walked down the Promenade Sir William Osler to the foot of Mont-Royal. It was a misty morning and a few drizzle drops fell from time to time. While there, the main staircase seemed endless to me but, 30 minutes later, I reached the Chalet du Mont-Royal. This trip was physically demanding but also unique, especially for my weakness for misty (and thus cryptic) landscapes.

My experience at The Neuro made me wonder about the unmet needs in my home country regarding the care of persons with epilepsy. I’m sure they are multiple and at different levels. Since my center is a public tertiary referral hospital, I think many of our most complex patients could benefit from long-term video EEG in an elective admission to a specialized inpatient setting (i.e., an EMU). Therefore, a first step might be to start an EMU here and, if successful, to extend this program to other strategic tertiary neurological services nationwide.

I finally want to acknowledge the World Federation of Neurology, The Neuro, and the Canadian Neurological Society for this great initiative that allowed me to experience the Canadian neurological system in an international environment, meet new colleagues, and foster future cooperation. I also want to thank Dr. F. Gonzalez-Crussi (Northwestern University), my long distance mentor, for his insightful comments on an earlier version of this report. •
