A case of corticobasal degeneration presenting with alien limb syndrome

摘要

Alien limb syndrome (ALS) is a very rare condition where the affected persons are not able to recognise the affected limb as their own, and regard it as being foreign or alien to them. We present a patient with ALS secondary to corticobasal degeneration, which is a rare neurodegenerative parkinsonian disorder. We discuss the clinical features, neuropathology and management of corticobasal degeneration.
