apraxia
Last reviewed 01/2018
Apraxia is defined as the inability to carry out purposive movements or actions that would otherwise be considered familiar. It results from a cerebral disorder, and is not associated with motor weakness or incoordination.
Apraxia for dressing is common in diffuse brain disease and inability to draw a 5 pointed star occurs in hepatic pre-coma.
Quite often the distinction between apraxia - the complete absence of this ability - and dyspraxia - an incomplete loss - is blurred.
