Pick's disease, also known as Pick disease and PiD, is a rare neurodegenerative disease. While the term Pick's disease was once used to represent a specific group of clinical syndromes with symptoms attributable to frontal and temporal lobe dysfunction, it is now used (at least among professionals in the field) to mean a specific pathology that is just one of the causes of the clinical syndrome now known as frontotemporal lobar degeneration. Some people still use the term Pick's disease to mean the more general clinical syndrome of frontotemporal lobar degeneration, but this has previously led to confusion among both professionals and patients and so its use should be restricted to the specific pathological subtype described below.
Pick's disease (the pathology) causes progressive destruction of nerve cells in the brain and causes tau proteins to accumulate into "Pick bodies" that are a defining characteristic of the disease.
