Affective psychiatric disorder is a general term for a large group of mental disorders in which high or low affect is the main manifestation. It includes first and recurrent depressive episodes, bipolar disorder (i.e., manic-depressive psychosis), manic episodes, and persistent affective disorder. People who have affective mental disorders are generally affected in many aspects of their lives. Manic episodes are easily provoked making conflicts with people, reckless spending can lead to severe credit card overdrafts, and hypersexuality can manifest itself in frivolous gender relations. In addition, there is a decrease in sleep at night, and a special tendency to take risks and behave recklessly. In depressive episodes, there is no energy to do anything because of low mood, lack of concentration and memory loss leading to reduced work efficiency, reduced initiative leading to alienation from others, reduced thinking ability, low self-esteem making a confident and decisive person become indecisive, very painful and life is like a year because they do not feel the joy of life, and even suicide. The most important principle for the treatment of affective mental disorder is early, systematic and thorough. Receiving treatment from a mental health specialist in a regular hospital is a prerequisite for full recovery, and the establishment of a good alliance between the patient, family and physician is an important guarantee for successful treatment. The treatment of affective mental disorders can be divided into medication (antidepressants, antimanic drugs, mood stabilizers, etc.), physical therapy (non-convulsive electroconvulsive therapy, transcranial magnetic stimulation therapy, light therapy, etc.) and psychotherapy (individual therapy, group therapy, family therapy, etc.) according to type. Our hospital has the above treatments with good results. The treatment of affective mental disorders is divided into acute treatment and maintenance treatment by time. The goal of acute treatment is to completely eliminate the symptoms of depression and mania, while the goal of maintenance treatment is to promote full recovery of social functions and prevent relapse. Generally speaking, the maintenance treatment time for patients with the first episode is 6 months to 1 year; the maintenance treatment for the second episode is 2 – 3 years; and those with three or more episodes should be treated for a long time.
