Ebola affected brains of survivors

February 25, 2016

Ebola survivors were found to have symptoms of brain abnormalities six months after they were first infected. Some symptoms include weakness, headache, memory loss, depressed mood and muscle pain.

Two people were suicidal and one had hallucinations. Common neurological findings on examination included abnormal eye movements, tremors and abnormal reflexes.

“While an end to the outbreak has been declared, these survivors are still struggling with long-term problems,” said study author Lauren Bowen, MD, of the (NIH) National Institute of Neurological Disorders and Stroke (NINDS) in Bethesda, Md., and a member of the American Academy of Neurology. “More than 28,600 people were infected with Ebola in West Africa during the outbreak. Of that number, 11,300 died. In collaboration with the ongoing PREVAIL III natural history study of Ebola survivors, we wanted to find out more about possible continued long-term brain health problems for the more than 17,000 survivors of the infection.”

For the study, a team of NINDS neurologists examined 82 Ebola survivors from Liberia with an average age of 35 years. At least six months after the start of their disease, most of the survivors had some neurologic abnormality.

The study was supported by NINDS and the National Institute of Allergy and Infectious Diseases, both components of the National Institutes of Health, and the Liberian Ministry of Health.
