Treatment for depression consists of two complementary actoins: treatment with medication with psychological follow-up, or psychotherapy.
The treatments proposed depend on the severity of the symptoms, the cause of the depression as well as the patients themselves.
Psychotherapy and medications are often suggested to complement each other, but psychotherapy may also be offered on its own in cases of mild depression. It is always recommended in all cases.
Medications for depression act upon the patient’s brain, helping them to resume normal function. They are tailored to the symptoms observed.
Hospitalization can be considered in very serious cases of depression, in patients presenting an imminent suicide risk or significant mental symptoms.
