What is cerebral atrophy?

A Answers (1)

  • Cerebral atrophy is a common feature of many of the diseases that affect the brain. The atrophy of any tissue means the loss of cells. In brain tissue, atrophy describes a loss of neurons and the connections between them. The atrophy can be generalized, which means that all the brain has shrunk; or it can be focal, affecting only a limited area of the brain and resulting in a decrease of the functions controlled by that area of the brain. If the cerebral hemispheres (the two lobes of the brain that form the cerebrum) are affected, conscious thought and voluntary processes may be impaired.
