Alzheimer Disease
Conditions
Brief summary
The Alzheimer's Plan 2008-2012 allowed the installation of therapeutic gardens for the structures welcoming patients with Alzheimer's disease (AD) . The physical, psychological and social benefits are the improvement of the state of health and overall well-being. There is a positive role in social interactions for patients with AD who can walk in the therapeutic gardens. Indeed, this promotes meetings with caregives and other people. Using the garden decreases the stress level in patients (Ulrich). The therapeutic garden named art, memory and life in NANCY is based on art, nature and regional culture. This garden can break with the artificial framework of care services often perceived as stressful. In the garden, people walk around and have an experience that could improve self-image perception. A clinical study with 2 groups of AD patients hospitalized in UCC or Cognitive Behavioral Unit took place in Nancy. The evaluation of the QCS (questionnaire on self-awareness) was carried out at the beginning and at the end of the study, * a group of patients went into the garden: the QCS score increased * a group of patients did not go to the garden (they remained in UCC): the QCS score decreased

Inclusion criteria

(If the last neuropsychological assessment dates from more than 3 months, these tests are carried out in routine care during the consultation was proposed and the consent obtained) * Symptomatic treatment of AD (anticholinesterase or memantine) if prescribed, at a stable dose for 1 month, stable psychotropic treatment for 1 month * Person affiliated with a social security scheme or beneficiary of such a scheme. * Patient over 18 years old. * Person received complete information on the organization of the research and having signed their informed consent.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| cerebral 18F-FDG PET-CT exam | up 20 days | Topography of brain regions, whose carbohydrate metabolism has significantly changed in cerebral PET / CT with 18F-FDG before and after using the Therapeutic Garden. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| cerebral 18F-FDG PET-CT exam | up 20 days | Topography of the brain regions, the carbohydrate metabolism of which has been significantly modified in cerebral PET / CT with 18F-FDG before and after the use of the therapeutic garden by people living with Alzheimer's disease by integrating the actimetry as co-variable in the model. |
| Comparison of QCS before and after using the therapeutic garden | up 18 days | QCS is a self-awareness survey to be asked to patients before and after using garden |
| cerebral 18F-FDG PET-CT exam with QCS | up 20 days | Topography of brain regions, whose carbohydrate metabolism covariates with clinical variables (QCS). |
| Modifications of the score of the electrodermal response during the use of the garden | up 14 days | Electrodermal response is measured with sensors placed on the skin |
| cerebral 18F-FDG PET-CT exam with neuropsychological assessment | up 20 days | Topography of brain regions, whose carbohydrate metabolism covariates with clinical neuropsychological assessment |
