Pick Disease Symptoms

The frontal lobes of the brain are the source of our rational emotional responses and the way we act in response to the world around us. This region of the brain also controls our use of speech and how we express language in all forms. Because Pick disease mostly affects this region of the brain, it is these thinking functions that are most often abnormal in people with the disease.

The symptoms of Pick disease vary widely from person to person. The symptoms are usually very subtle at first and worsen slowly. The rate of worsening also varies from person to person.
