A single blow to the head may increase the risk of Parkinson's disease by more than 50 percent, according to new research.

The study of 325,870 Army veterans shows that people who have had a mild concussion, or mild traumatic brain injury, have a 56 percent higher risk of developing the neurodegenerative illness which killed star boxer Muhammad Ali.

Findings - Today - NFL - Years - Billions

The findings, published today, could be problematic for the increasingly-embattled NFL, which has spent years - and billions of dollars - trying to dismiss the idea that tackle football is not as dangerous to players as scientists claim.

It comes amid a huge swell in research showing that attempts to curb the rate of concussions may not be enough: even subconcussive hits, or just one debilitating hit, could sew the seeds for crippling neurodegenerative diseases including CTE, Alzheimer's and Parkinson's.

Senior study author Professor Kristine Yaffe, of the University of California, San Francisco, said: 'Previous research has shown a strong link between moderate to severe traumatic brain injury and an increased risk of developing Parkinson's disease but the research on mild traumatic brain injury has not been conclusive.

'Our research looked at a very large population of U.S. veterans who had experienced either mild, moderate or severe traumatic brain injury in an effort to find an answer to whether a mild traumatic brain injury can put someone at risk.'

Moderate - Brain - Injury - Loss - Consciousness

Moderate to severe traumatic brain injury was defined as a loss of consciousness for more than 30 minutes, alteration of consciousness of more than 24 hours or amnesia for more than 24 hours.

Mild traumatic brain injury was defined as loss of consciousness for zero to 30 minutes, alteration of consciousness of a moment to 24 hours or amnesia for zero to 24 hours.
