Alzheimer's disease is the leading cause of dementia worldwide. The first cognitive function to be affected is memory. As the disease progresses, other cognitive systems are affected, leading to a gradual loss of independence for the patient. This loss of independence is at the heart of the psychosocial and medico-economic challenges posed by Alzheimer's disease. Functional independence refers to the patient's ability to perform activities of daily living. The evolution of autonomy varies significantly from one individual to another, and a specific, personalized assessment is necessary in order to offer appropriate care and services. There is a link between patient autonomy and psycho-behavioral disorders. Early identification of loss of autonomy in connection with psycho-behavioral disorders would allow specific treatment to be put in place.
The study hypothesis is that there is a link between changes in smartphone data and changes in the independence of patients with AD.
Age ≥ 60 years
Patient consulting on routine care at a memory resource and research center for Alzheimer's disease defined by cognitive memory complaints from the patient or their family and friends, evidence of impaired verbal episodic memory storage in FCSRT defined by a sum of FR values less than 17/48 and a sum of CR values less than 40/48 compared to the patient's age and socio-cultural level and no criteria on other neuropsychological tests, progressive decline over at least 6 months affecting independence, and if a brain MRI, a lumbar puncture, and/or an 18FDG PET scan were performed as part of the patient's routine care, the results must be consistent with a diagnosis of MA.
