Old age (> 60 years) is at high risk to develop major depression disorders (MDD). MDD doubles the risk for subsequent cognitive disorders and dementia. Apathy (i.e. the lack of motivation) is a core problem in depression in older age and is frequently associated with cognitive decline in people who have mild cognitive disorders. The investigator propose here to combine actimetry (the measurement of motor activity using a simple device worn at the wrist) and brain imaging to show that it's possible to measure apathy using actimetry in a population of elders with MDD. Having shown that apathy can reliably be measured with actimetry and that it is associated with brain abnormalities, the investigator will be able to test whether actimetry can predict cognitive decline in elders with MDD and can be routinely used in a day-to-day medical practice.

| Mattis Dementia Rating Scale | Other | This scale was developed to assess the cognitive status of patients with neurodegenerative diseases. There are 37 items that are presented in a fixed order and grouped into five sub-scales: attention, initiation, construction, conceptualization and memory. Patients and healthy subjects with a score below 125 are not included because of major cognitive impairment. |

| Unified Parkinson 's Disease Rating Scale-III | Other | This scale is used to rate the severity of extra-pyramidal symptoms (akinesia, rigidity and tremors). These symptoms may be the cause of reduction of motor activity apart from any reduction in motivation, they onstitute a confounding factor that it should be controlled. |
|
| Mini Neuropsychiatric Investigation | Other | This is a structured interview that allows rapid screening in about 20 minutes of troubles Psychiatric. It is based on short questions to which the patient must answer yes or no and on a decision tree. Patients must validate clinical diagnoses of depression. |
|
| Montgomery and Asberg depression Rating Scale | Other | This scale is composed of 10 items from 0 to 6 from a semi-structured interview, to obtain a total depression score of 0 to 60 (0 no depression, 60 maximum intensity of depression). |
|
| Clinical Global Impression | Other | heterosexual assessment that rates the severity of symptoms suicidal and changes in suicidal symptoms. Any subject with a score greater than 4 is not included. |
|
| Apathy diagnostic criteria | Other | The clinical criteria make it possible to make a diagnosis of apathy with a functional repercussion. It is based on a lack of motivation felt by the patient, causing a functional or social impact that is not the consequence of a disturbance of consciousness or a disability engine. The cognitive, emotional and behavioral dimensions are affected. |
|
| walking speed test | Other | The patient is timed to walk 10m. A speed <1m / sec is a criterion exclusion because it shows severe sarcopenia and constitutes a bias. |
|
| accelerometer presentation | Other | accelerometer presentation and pose |
|
| data acquisition from the accelerometer | Other | withdrawal of the accelerometer and data acquisition from the accelerometer |
|
| Apathy Evaluation Scale, | Other | clinician version and near-helping version. It's a hetero rating scale from an interview semi structured by a trained clinician. It assesses cognitive, emotional and behavioral apathy than three items of various apathy. The total score ranges from 18 (total absence of apathy) to 72. |
|
| fatigue Visual Analog Scale | Other | To date, there is no valid fatigue scale in the depression of the elderly subject, a fortiori in French. The fatigue scale in adult depression includes has been validated with an EVA (Visual Analogue Scale) (38). We therefore propose to use this type of evaluation to control this aspect. |

| Apathy Motivation Index | Other | This is a self-questionnaire of 18 items, each side on a 5-level Likert scale (0: not everything at 4: very often). It differentiates between "behavioral" apathy and "social" apathy. "Emotional". |
