New research adds to a growing evidence that sports that involve repeated blows to the head may lead to dementia.

Measuring cerebral blood flow is important for diagnosing strokes, and for predicting secondary damage in hemorrhages or traumatic brain injuries.

An enzyme called chondroitinase ABC that regrows damaged nerve tissue in animals has been too unstable for human use. New work could change things.
