[Circadian rhythm disorders, motivation and Alzheimer's disease].
In Alzheimer's disease, when the breakdown of the sleep's circadian rythm is sudden, it reflects frequently a concomitant somatic or psychiatric disorder. If the trouble appears progressively, there is less pathological or disturbing behaviors in the beginning. Later, it is often associated with a loss of interest for the daily living activities (perte de motivation).
