Cognitive-Neuropsychological Aspects

ByFabienne Collette, Martial Van der Linden, Anne-Claude Juillerat, and Thierry Meulemans

Consequently, neuropsychologists have searched for a typical cognitive AD profile (“the essence” of AD deficits). The adoption of cognitive psychology concepts and methods in the neuropsychological approach of AD has largely modified this point of view (see Van der Linden, 1994; Venneri, Turnbull, & Della Sala, 1996).
