The treatment will start with Sertraline (SSRI) - doses of 50 mg and adjusting as necessary according to the patient's profile. After 8 weeks, if the patient experiences remission, they will continue on monotherapy with Sertraline. In case of relapse Bupropion, Quetiapine, Lithium or Aripiprazole might be add-on. In this case, add-on medications will be determined according to the patient profile, by the clinician. If there is a response above 25% of the symptoms, but without remission, the patient will proceed to augmentation with the aforementioned medications and if there is no improvement of at least 25%, the patient will be considered drop-out. Associations with Lorazepam if necessary will be allowed in any phase of the study.
