A recent study suggests that dementia may not be exclusive to older adults, indicating that traumatic brain injuries can trigger neurodegenerative diseases prematurely. Conducted by the University Hospital of Helsinki, the research analyzed data from over 40,000 adults, finding that severity of head injuries correlates with higher dementia risk, particularly in individuals aged 41 to 50. Additionally, while relationships between head trauma and Alzheimer’s were noted, no link was established for Parkinson’s disease or amyotrophic lateral sclerosis (ALS). The World Health Organization has projected that such injuries will become a leading cause of disability and death within the next decade.
