<unk>  is a rare neurodegenerative disease. While the term<unk>  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<unk>  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
Parkinson's disease
Wright dick syndrome
Menkes disease
Alzheimer's disease
Sandhoff disease
Early-onset Alzheimer's disease
Wernicke-Korsakoff syndrome
