[Olfaction and Alzheimer's disease: from deficits to therapeutic hopes].

Odors are known to entertain a special link with memory: once the meaning of an odor has been learned, it naturally acts as a retrieval cue of the learning context, along with the emotions and behaviors associated with it. The existence of this link has for several years inspired the study of olfactory function in Alzheimer's disease (AD), known for the memory disorders it causes. The aim of this review is to summarize the current scientific knowledge on the almost paradoxical dual role played by odors in the management of AD, as both screening and therapeutic tools.

Sensory Cueing of Autobiographical Memories in Normal Aging and Alzheimer's Disease: A Comparison Between Visual, Auditory, and Olfactory Information.

Background: Alzheimer's disease (AD) is a chronic, neurodegenerative disease resulting in a progressive decline of autobiographical memories (AMs) which favors the development of psycho-behavioral disorders. One of the most popular psychosocial interventions in dementia care, Reminiscence Therapy, commonly uses sensory cueing to stimulate AMs retrieval. However, few empirical studies have investigated the impact of sensory stimulation on AMs retrieval in AD.

Investigating Eye Contact Effect on People's Name Retrieval in Normal Aging and in Alzheimer's Disease.

Difficulty in recalling people's name is one of the most universally experienced changes in old age and would also constitute one of the earliest symptom of Alzheimer's disease (AD). Direct gaze, i.e.
