Last year, The Institute for Health Metrics and Evaluation (IHME) produced the most comprehensive study to date on neurological conditions, globally. The most compelling find: the burden of nervous system (neurological) conditions is much greater than previously understood, with this diverse group of conditions affecting 43% of the world’s population (3.4 billion individuals) in 2021.
The biggest contributors to neurological health loss globally were stroke, neonatal encephalopathy (brain injury), migraine, Alzheimer’s disease and other dementias, and diabetic neuropathy (nerve damage).
