Brief summary
Analysis of 4 CSF Alzheimer's disease biomarkers (total and phosphorylated tau protein, Aß40 and Aß1-42) and morphological brain MRI in older patients (\>60 year's old) with bipolar disorder, after an evaluation of their cognitive functions. Comparison between two groups of patients : patients with cognitive disorders and patients without cognitive disorders. The objective is to describe and compare the profile of those biomarkers in those two populations.
Detailed description
Describe the profile of the 4 neurodegeneration's biomarkers of Alzheimer's disease dosed in the cerebrospinal fluid (Total Tau proteins, phosphorylated, Aß40 and Aß1-42) for old subjects suffering from bipolar disorder with or without cognitive impairment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Profile 4 neurodegeneration's biomarkers of Alzheimer's disease dosed in cerebrospinal fluid of aged subjects with bipolar disorder : Total Tau proteins, phosphorylated Tau proteins, Aß40 and Aß1-42 concentration | 3 hours 50 minutes (total of the 4 primary outcome measures described) | The mean concentration of each biomarker is measured independently. The analysis between the 2 groups is done with the profile of the 4 biomarkers, not only between the profile of one biomarker to another. |
