Detaljert beskrivelse
The secondary objectives of this study are:
A. Evaluate other aspects of cognitive functioning (using the Tower of London, the Probabilistic Reversal-learning task, the Rey Complex Figure, the Reading the Mind in the Eyes test) in euthymic patients with bipolar disorder, depending on the presence or absence of a history of suicide attempt; B. Explore performance on neuropsychological tests depending on the type of therapy administered (lithium salts or valproate monotherapy or in combination with other mood stabilizers); C. Explore a possible relationship between circulating levels of lithium or sodium divalproex results and different neuropsychological tests; D. Establishment of a biobank for this population with leftover blood samples following serum lithium or divalproex testing.

- The patient was correctly informed about the study
- The patient must be insured or beneficiary of a health insurance plan
- The diagnosis of bipolar disorder is confirmed by the doctor referring the patient to the BEC and confirmed during the preliminary interview at the BEC
- The patient is euthymic on the day of inclusion. This is supported by a short psychiatric interview conducted at the BEC and the completion of the depression and mania scales (score <= 7 on the HDRS questionnaire and score <= 7 on the YMRS questionnaire).
- The patient is prescribed a mood stabilizer based on lithium or divalproex.
Exclusion Criteria:
- The patient is under judicial protection, under tutorship or curatorship
- The patient formalizes his/her opposition to the studyd
- It is impossible to correctly inform the patient
- The patient has mental retardation
- The patient has practiced substance abuse or dependence within the 6 months prior to study inclusion (alcool, cannabis, opiates, psychostimulants)
- The patient does not meet euthymic criteria (score <= 7 on the HDRS questionnaire and score <= 7 on the YMRS questionnaire).
Uninclusion Criteria:
- The patients withdraws consent during the study
- The patient does not understand directions necessary for the neurpsychological tasks
- The patient is not able to use a computer to complete the neuropsychological tasks
