ST. LOUIS (KMOX) - A new study suggests brain trauma slightly increases the risk of stroke later in life, especially for people under the age of 50.

That means a head injury, even from a small fall or an auto accident, may cause abnormal clotting in the brain or damage to the brain’s blood vessels which might not be seen for years down the road.

Neurologist Dr. Aloka Amarakone at the SSM Neuroscience Institute at St. Clair Health Center says this is a small study out of the University of Michigan and he would like to see a much larger study to verify these results.

“Maybe we can look at a few more studies…to see if this is consistent,” he suggests.

Amarakone says the finding could help explain strokes in younger people who don’t possess typical stroke symptoms such as hypertension, Type 2 diabetes, or atrial fibrillation.
