Les troubles cognitifs de la maladie d'Alzheimer et des syndromes apparentés : pourquoi et comment les explorer ?

Dramatic improvement in early diagnosis of Alzheimer's disease has become possible thanks to better knowledge of the neuropsychology of early symptoms. The most sensitive tests are clearly memory tests, early markers of symptoms. Episodic memory is at best evaluated by registration controlled tasks. However, the first evaluation must screen all cognitive domains: language, praxias, gnosias, executive function and reasoning. Considered together and compared with the results of the physical examination enables an enlightened differential diagnosis between Alzheimer disease, frontotemporal lobar dementia and Lewy body dementia.
