[Procedural learning and neurological disorders]

We review the current state of learning procedures in six neurological conditions: amnesia, Alzheimer-type dementia, Huntington's disease, Parkinson's disease, progressive supranuclear paralysis and cerebellar pathology. In each condition the conservation or deterioration of different types of ability is specified: motor and percepto-motor abilities were evaluated using different tests such as following a rotating disk or signal, the labyrinth test, percepto-motor adaptation test or tests using paradigms of time of serial reaction; percepto-cognitive abilities evaluated by 'mirror-reading' and cognitive abilities evaluated by the Tower of Hanoi, of Toronto, or of London.

Most of the papers published describe conservation of learning procedures in amnesic syndromes, relatively conserved in Alzheimer's disease and relatively deteriorated in Huntington's disease, in progressive supranuclear paralysis and in cerebellar dysfunction.
