Cerebral Atrophy Disability is the gradual, progressive loss of brain cells. Atrophy is a trait that is typical of certain diseases that affect the brain. “Atrophy” means the wasting away, or the decrease in mass, of a part of the body. When brain tissue atrophies, or shrinks, there is loss of neurons and connections between the neurons. Cerebral atrophy can occur throughout the entire brain or in one select region of the brain.
The progressive wasting away of brain cells generally leads to the loss of neurological function. Commonly associated with dementia and Alzheimer’s, cerebral atrophy can be caused by many medical conditions that act to destroy brain tissue.
While the condition itself may not be a recognized “impairment” in some medical listings, many of the causes of cerebral atrophy – such as Lou Gehrig’s disease (ALS), Parkinson’s and Huntington’s disease – are.
