Corticobasal Degeneration
Background
Corticobasal Degeneration: CBD
CBD is a rare form of dementia. It is an heterogeneous disease (i.e. composed of different elements), and is characterised by a combination of cognitive impairment and movement disorder.
In a review by Rinne in 1994 the authors found only forty cases. However, CBD is difficult to diagnose. Studies have shown that a clinical diagnosis may be different from neuropathology, i.e. a diagnosis made after examining brain tissue damage which would be revealed at autopsy.
