Pick Disease of the Brain


Pick's disease is a rare and permanent form of dementia that is similar to Alzheimer's disease, except that it tends to affect only certain areas of the brain.


The disease can get worse slowly. Tissues in the temporal and frontal lobes of the brain start to shrink over time. Symptoms such as behavior changes, speech difficulty, and impaired thinking occur slowly, but continue to get worse.

The early personality changes can help doctors tell Pick's disease apart from Alzheimer’s. Memory loss is often the main, and earliest, symptom of Alzheimer's.

People with Pick's disease tend to behave the wrong way in different social settings. The changes in behavior continue to get worse and are often one of the most disturbing symptoms of the disease. Some patients will have difficulty with language (trouble finding or understanding words or writing).
