Concussion increases the risk of developing dementia by 72 percent
- Medical records from concussion patients showed a 72 percent increased risk of dementia
- Concussion patients were 57 percent more likely to develop Parkinson's
- Scientists in Canada say that an increased risk could be due to impaired blood flow to the brain
A concussion increases the risk of developing dementia and Parkinson's disease later in life.
Medical records from 47,483 concussion patients who were followed up for 25 years showed that they had a 72 percent increased risk of dementia compared to those who had not suffered a brain injury.
Concussion patients were 57 percent more likely to develop Parkinson's disease and 72 percent more likely to have mood and anxiety disorders.
Women with concussion were 28 percent more likely to develop attention deficit hyperactivity disorder and 7 percent more likely to have mood and anxiety disorders than men.

Scientists from the University of Manitoba, Canada, say the increased risk of neurological problems may be due to poor blood flow to the brain or a disorder of key hormones like cortisol. The results of the study were published in the BMJ journal Family Medicine and Community Health.
A team of Canadian researchers examined data on nearly 50,000 people who had concussions between 1990 and 1991, and followed up on their health in 2014 and 2015.
They compared 28,021 men and 19,462 women who had suffered a concussion in the early 1990s with almost 140,000 healthy participants who had not suffered a concussion.
The authors wrote: “Concussions were associated with an increased risk of diagnosing attention deficit hyperactivity disorders, mood and anxiety disorders, dementia and Parkinson's later in life.
"Our results suggest that concussion can be a risk factor for the development of comorbid conditions in the years after the first injury."
Concussion is classified as a temporary brain injury caused by a bump, blow, or blow to the head.

It usually lasts up to a few days or weeks, although it sometimes needs emergency treatment and some people can have longer-lasting problems.
Signs of concussion usually appear within a few minutes or hours after a head injury, but can last up to a few days.
Symptoms may include: headache that does not go away or is not relieved with pain relievers; Dizziness; feeling sick or being sick; Memory loss; Clumsiness or balance problems; feeling stunned, dazed, or confused; Changes in eyesight; being knocked out or fighting to stay awake.
Concussions are more difficult to detect in young children and babies.
Caregivers are urged to watch for changes in their normal behavior after a head injury, such as: For example, excessive crying, differences in their eating or sleeping habits, or a loss of interest in people or objects.
There is no guaranteed way to prevent concussions, but people can follow simple safety precautions such as wearing a helmet while cycling or wearing the recommended equipment when participating in a contact sport like rugby or boxing.
