The main objective of the study is to evaluate the use of EEG in the management and follow-up of neuropsychiatric disorders. Secondary objectives are therefore better understanding of the pathological activations in neural network during neuropsychiatric disorders, their clinical evolution and response to therapies.

Patients are having EEG recordings as a routine part of their clinical evaluation and diagnosis. EEG recording is harmless, has no side effects, any radiation or any mechanical or electrical influence. It is of short duration and may be done in the EEG institute or the patient's room.
