A single moderate-to-severe traumatic brain injury, can disrupt proteins that regulate an enzyme linked to Alzheimer’s disease.
That conclusion is from researchers at Tufts University School of Medicine.
They found that even one traumatic brain injury could result in elevation of the enzyme, BACE1 in the brain.
Kendall Walker is with the department of neuroscience at the University.
He says the enzyme causes elevated levels of amyloid-beta, in the brain and that’s associated with Alzheimer-s disease.
Moderate-to-severe traumatic brain injuries are caused most often by traumas, such as severe falls or motor vehicle accidents, but not all traumas to the head result in the enzyme build-up.
The study was published in The Journal of Neuroscience.
