In a finding that suggests football used to be a less dangerous sport, a small study shows that men who played in high school in the 1950s and 1960s may not be at increased risk for dementia or memory problems.
Nor did they show increased rates of Parkinson's disease or amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease.
The study used a small group of men, the researchers acknowledged. But, they added, the results are in line with an earlier study that examined men who'd played high school football in the 1940s and 1950s.
