The American Academy of Neurology released a comprehensive study last week, just before the 2012 NFL football season began, that confirms significant previously held beliefs that head injuries cause neurologic problems later in life. The study, published in the medical journal Neurology, followed approximately 3500 retired professional football players, and found that professional football players were three times more likely to have neurodegenerative diseases than the general population.
The study also found that professional footballers were at a four times greater risk of developing amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease.
The study found a higher incidence, compared to the general population, of players afflicted with Alzheimer’s and Parkinson’s disease.
Finally, the study found that players, compared to the general population, were at an increased risk of dying from a neurological disorder.
