Around 1/3 of people who have a mild traumatic brain injury develop ongoing symptoms after a concussion, and now Canadian scientists have identified what makes some people more likely to experience these longer term issues. Pooling together the results across 15 studies and almost 600,000 people, they found that acute cognitive symptoms (such as difficulty concentrating), a history of anxiety and/or depression or of sleep disorders, and the presence of clinical signs such as loss of consciousness and amnesia, were all linked to a higher chance of developing persistent symptoms.
