[A garden as a care tool in a cognitive-behavior unit].

Cognitive-behaviour units are specialised units within follow-up and rehabilitation care services for people suffering from Alzheimer's disease. These units were created in response to measure 17 of the 3rd Alzheimer's Plan. To stabilise behavioural disorders, as part of a non pharmacological care plan, the therapeutic garden is a useful care tool. This article presents an original initiative in Nancy.
