Rochester Scientists Show How Thinking Can Harm Brain Cells

Scientists at the University of Rochester Medical Center have targeted
a new culprit and method of attack on neurologic functions in diseases
such as HIV-1-associated dementia and Alzheimer's.

In an article in the Nov. 1 issue of The Journal of Clinical
Investigation, the Rochester scientists describe a new mechanism by
which brain cells can be damaged during chronic neurodegenerative
diseases. When inflammation occurs in the brain, nerve impulses that
are passed between cells during routine activities like learning and
memory can become toxic. Instead of triggering the formation of
memories, these impulses can inflict injury on neurons and disrupt
neurologic function.
