CHICAGO (Reuters) - An athlete who suffers a concussion may need a week or longer to recover and is at higher risk of being re-injured, a pair of studies said on Tuesday.
About 300,000 sport-related concussions occur each year in the United States, making the injury among the most common suffered by college football, ice hockey and soccer players.
A concussion occurs when a blow jostles the brain inside the skull, stretching and sometimes tearing nerve cells and often leading to symptoms such as headaches, dizziness, fatigue, memory problems, poor concentration and impaired balance.
