title: [Identification and memorisation of emotions in Alzheimer's disease: a critical review of litterature].
abstract: Although the first signs of Alzheimer's disease (AD) mainly affect episodic memory and executive functions, emotional disturbances also have a considerable impact on the mental and relational capacities of AD patients. In AD, the early impairment of amygdala structures, whose central role in the recognition and memorisation of emotions has previously been demonstrated, has led researchers to focus on the possible implications of such impairment in generating cognitive disturbances or behavioural troubles in these subjects. Several studies have shown that emotional processes are altered in AD, and can contribute to varying degrees to deficits in terms of social cognition, and to the generation of behavioural troubles. This review will detail the main avenues of research into the capacity to identify and memorise emotions in AD, and summarise the often conflicting results that have, to date, prevented the emergence of a general consensus concerning the emotional processes. It seems thereby legitimate to question about different elements that can explain these conflicting results, such as the existence of various theories, divergences about the definition of emotions and important methodological differences.
