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.

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.

Research Projects

Platelet Signatures in Multiple Sclerosis

We are recruiting individuals with multiple sclerosis to help identify markers for the disease in the blood to make diagnosis easier. Participation includes a one-time blood draw and a short survey. Visits can be scheduled around infusions or other medical appointments at Massachusetts General Hospital.

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. This research study is to investigate if light therapy can be a potential treatment option for MS-related fatigue.
