Global Neurology Research Group

The Global Neurology Research Group, part of the Department of Neurology and the Neurological Clinical Research Institute, finds innovative solutions to improve the quality of neurological care in low- and middle-income countries.


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.

Mateen symposium

2018 Regional RNDS

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). Learn more.

Thanks to Sumaira Foundation

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.

First conference a success

The first Treatment and Research in Multiple Sclerosis 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

Support Mass General Neurology

Thanks for supporting Massachusetts General Hospital Neurology in a 5K organized by the New England-based McCourt Foundation. The McCourt Foundation is dedicated to building a community to assist those affected by neurological disorders using research and the power of giving, to enhance the lives of patients and their families. The McCourt Foundation will be matching proceeds raised by each MGH Neurology team member — meaning 100% of funds raised plus the McCourt match, will directly benefit neurology research at Mass General.

Impact of Poorly Controlled Epilepsy in the Republic of Guinea

A new paper from the Global Neurology Research Group in the journal Seizure finds there is an urgent need to improve the standard of care for people with epilepsy in Guinea. Several missed opportunities were identified, including low use of AEDs and high use of traditional medicines, particularly in children. Targeted programs should be developed to prevent unintentional injury and improve seizure control.

Mateeen Pierre Foundation award

Mateen wins Global Observatory eHealth award

Dr. Mateen has received a 2018 Global Observatory eHealth Award from the Pierre Fabre Foundation. She was recognized for the Guinea Epilepsy Project, of which she is the principal investigator, along with the Guinean-Mass General team.

The awards are designed to identify, document, promote and help develop eHealth initiatives that improve access to quality healthcare and medicines for the most disadvantaged populations in resource-limited countries. It stands as the leading resource and gateway for development of eHealth in the Global South.

Thank you to our funders

The Global Neurology Research Group would like to thank our funding partners for helping to make our research possible.

Group Travels to West Africa to Consult with Epilepsy Patients

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.

A Global Atlas of NMO Diagnosis and Treatment Practices

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).


Platelet Signatures in Multiple Sclerosis

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

Light Therapy for Fatigue in 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

MAMBO: Treating Post-Stroke Disability in Tanzania with Fuoxetine

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.

Smartphone EEG in Bhutan and Guinea

Testing the EEG system in Bhutan

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).

  • Optical Coherence Tomography to Assess Infant Brain Development in Sub-Saharan Africa and Central Asia

Educational Resources

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.

2018 Epilepsy Survey

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.
