The Global Neurology Research Group is dedicated to finding practical and cost-effective solutions to meet the neurological needs of individuals in developing countries.
Neurological disorders such as epilepsy, stroke, dementia and traumatic brain injuries are more common in low- and middle income countries, where 86% of the world’s population is concentrated.
These neurological disorders can be disabling both physically and mentally, and there is a high human and economic cost associated with them. Many of these diseases come with a stigma attached since they are often misunderstood.
Compounding this problem is that many of these diseases are not well diagnosed or treated due to a lack of trained neurologists and limited access to medical care in these settings.
When last studied, there were 12 African countries with no neurologists, and an additional 23 countries with a ratio of one neurologist to more than five million people in the population.
The Global Neurology Research Group at Mass General works on projects designed to improve the diagnosis, care and treatment of neurological diseases in these resource-limited settings.
For Rare Disease Day we are highlighting neuromyelitis optica (NMO) and Farrah Mateen, PhD, the Mass General neurologist dedicated NMO research.
"The science of NMO is fascinating to me and I have been very excited to see how much the field has changed over the past decade. I have been inspired by many patients along the way, and I consider each of them essential in the fight to understand, treat, and one day cure NMO."

Between July and November of 2018, the Global Neurology Research Group surveyed physicians in over 140 across the globe about diagnosis and treatment practices for neuromyelitis optica (NMO). We received complete responses from 60 countries spanning a range of geographic regions and income levels. These responses helped us understand the extent to which income level and geographic region may affect a physician’s ability to treat and even diagnose the disease.
In one of our key results, we found that physicians in lower-income countries appear to have a markedly reduced access to the newest generation of NMO diagnostic tests. This especially holds true for countries in Africa and the Eastern Mediterranean. This is important because NMO is often confused with another, similar disease – multiple sclerosis – but the treatments for the two diseases are different. Without access to the best diagnostic tools, patients in low-income countries might not receive the best care possible.

Dr. Mateen spoke at the Regional Rare Neuro-Immune Disorders Symposium in Boston on Oct. 27. The event offered education and advocacy for families, caregivers and patients with acute disseminated encephalomyelitis (ADEM), MOG antibody-associated disease (MOG-Ab disease), neuromyelitis optica spectrum disorder (NMOSD), optic neuritis (ON), and transverse myelitis (TM) (including the subtype acute flaccid myelitis).

Sincere thanks to Sumaira Ahmed, of the Boston-based Sumaira Foundation, for her Foundation's support of the Mass General Global Neurology Research Group. We are now conducting a worldwide survey of neuromyelitis optica diagnosis and treatment through a grant from the Sumaira Foundation.
The first Treatment and Research in Multiple Sclerosis online (triMS.online) conference was completed successfully on November 27, 2018. This conference was steered by a diverse committee of scientists, including Dr. Mateen, from five continents. The conference, which included a debate on cognition monitoring in MS care, enabled MS specialists from across the globe to learn and debate the clinical practice of MS treatment without the time and expense of international travel

The Global Neurology Research Group in collaboration with neurology resident physicians at the Ignace Deen Hospital in Conakry, the capital city of the Republic of Guinea in West Africa, consulted on >130 new patients with epilepsy this month. Guinea is a low-income country, recently publicized for surviving a large Ebola outbreak.
Radio Television Guinea covered our epilepsy research endeavor and announced the free consultations and medicines to people with epilepsy, bringing in patients from throughout the country. Several patients came from far away (as far as 800 kilometers, or more than one day's travel). Many patients had seizure related burns and injuries and reported >100 seizures each. Traditional medicines were as common as antiepileptic drug provision.
This new partnership with the neurology team in Guinea—including residents from Niger, Benin, Chad, Cameroon, and Guinea itself—is meant to de-stigmatize epilepsy, provide care and support to patients and practitioners, promote medication treatment, and ultimately bring epilepsy "out of the shadows" in one of the world's lowest income countries.

Neuromyelitis optic (NMO) is a demyelinating disease of the optica nerve and spinal cord. Despite recent advances in the treatment and diagnosis of NMO, little is known about the global availability of diagnostic tests and medications for the disease. We surveyed physicians from over 120 different countries on the availability, affordability, and accessibility of a variety of clinical options to diagnose and treat neuromyelitis optic (NMO).
When faced with clinical symptoms of multiple sclerosis (MS), a neurodegenerative condition, patients and physicians can be uncertain of how to proceed. There are multiple diseases that mimic the symptoms of MS; some of them require special treatment and care. A blood test for MS could allow physicians to more confidently direct the care of their patients; unfortunately, no such blood test currently exists. But there is evidence that platelet RNA signatures may change in MS patients. We are analyzing the blood of MS patients, healthy patients, and patients with MS-mimicking diseases to determine whether there is a platelet-based RNA signature that can help confirm diagnosis of multiple sclerosis
Fatigue is the most commonly reported symptom among people living with MS, and more than a quarter report fatigue as their most disabling symptom. We are conducting a double-blind, placebo-controlled clinical trial to determine whether light therapy can be used as a treatment for MS-related fatigue

Fluoxetine has shown promise as a pharmacological treatment for motor recovery after stroke, but its use for such indications has not been tested in the low-income countries that bear the greatest burden of stroke disability and mortality.
In the MAMBO (Kiswahili for “Hello”) clinical trial, we will test the safety and tolerability of fluoxetine for post-stroke motor recovery in Tanzania. Funded by the National Institutes of Health.
The group is conducting a clinical study to test the feasibility of using a smartphone-based electroencephalograph (EEG) system to diagnose patients with epilepsy in Bhutan, a small, land-locked country between China and India, and Guinea, a country on the Atlantic coast of Africa bordered by Mali and Sierra Leone. Funded by the Charles Hood Foundation, the Harvard University Asia Center and the National Institutes of Health (NIH).

Stroke is the leading cause of mortality globally, and lower-income countries are the most severely affected. There is a high burden of stroke in Tanzania, a low income country in sub-Saharan Africa.
In this study we aim to characterize the risk factors, including HIV, for post-stroke disability, mortality, and depression.

Preliminary data suggest that retinal nerve fiber layer measurements may be surrogate markers of early life cortical development. Embryologically, the retina shares derivation with the cerebral cortex, but unlike the cortex, can be visualized non-invasively through a new technology, optical coherence tomography (OCT).
OCT is a portable, affordable, painless, noninvasive medical instrument and has supportive scientific evidence as a surrogate marker of gross measures of neurodevelopment in specific disease states. Interpretation of RNFL thicknesses are automated and colorized so that lay community health care workers can be trained to make basic readings in the field.
We aim to determine whether handheld, noninvasive OCT equipment can reliably assess brain development through measurements of retinal nerve fiber layers in early life and be an effective screening test for some forms of abnormal early life brain development.
The Global Neurology Research Group at the Massachusetts General Hospital (MGH), which Dr. Mateen (PI) lead, has a list of free educational resources for patients and investigators including survey instruments and links to publications. The survey instruments will also be included as appendices in any published papers.
This is the clinical and demographic survey form we have developed for the continuation of the epilepsy study in Bhutan and Guinea. The survey is designed to collect important data for those with epilepsy in resource-limited settings including questions about seizure frequency, diagnosis, treatment, social networks, depression, and sleep quality. Please feel free to download the survey and modify for use in other countries as needed.

Congratulations to Kate Brizzi, Sonam Paydon, Tshokey, Damber Nirola, Lhab Tshering, and colleagues on their publication on neurocysticercosis among people with epilepsy in Bhutan. This study suggests a significant proportion of epilepsy in Bhutan is treatable and preventable.
It also guides the use of diagnostic tests for Taenia solium, a parasitic tapeworm, through research performed by the Neurocysticercosis Working Group referral lab in Lima with Professor Hugo Garcia and the Bhutanese medical laboratories in Thimphu.
The Bhutan Epilepsy project was referenced in a recent article in Nature. "[Dr. Mateen's] study of 205 people with epilepsy in Bhutan, now in review at a journal, showed that the app could reliably detect this neural activity — allowing health-care workers with little training to identify the type of epilepsy someone has and which drug could best treat it."
The Global Neurology Research Group team is pleased to join the The Health and Aging Study in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) at the University of Witwatersrand in Agincourt, South Africa this month.
Farrah Mateen, MD, PhD, divides her time between seeing patients at Massachusetts General Hospital and traveling across the globe researching innovative solutions for global neurological care.
The Global Neurology Research Group would like to thank our funding partners for helping to make our research possible.
