Know the causes. Brain atrophy is shrinking of the brain caused by the loss of its cells, called neurons. Two types of brain atrophy can occur; generalized and focal. Generalized atrophy refers to neuron loss throughout the entire brain, and focal atrophy refers to neuron loss in a specific brain region.
Associated Diseases/Disorders: The pattern and rate of progression of cerebral atrophy depends on the disease involved. Diseases that cause cerebral atrophy include: 1  stroke and traumatic brain injury. 2  Alzheimerâs disease, Pickâs disease, and fronto-temporal dementia.3  cerebral palsy, in which lesions (damaged areas) may impair motor coordination. 4  Huntingtonâs disease, and other hereditary diseases that are associated with genetic mutations.iseases that cause cerebral atrophy include: 1  stroke and traumatic brain injury. 2  Alzheimerâs disease, Pickâs disease, and fronto-temporal dementia. 3  cerebral palsy, in which lesions (damaged areas) may impair motor coordination.
