Depression

Depression: Are you depressed? Answer yes to (5) or more of these questions, and you may have major depression. Criteria: (5) or more of the following symptoms have been present during the same two week period and represent a change from previous functioning.

1) depressed mood most of the day, nearly every day, as indicated by either a subjective report (feels sad or empty) or observation made by others (appears tearful). Note: In children and adolescents, can be irritable mood.

(2) markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day.

(3) significant weight loss when not dieting or weigh gain (a change of more than 5% of body weight in a month), or decrease or increase in appetite nearly every day. Note: In children, consider failure to make expected weight gains.

(4) insomnia or hypersomnia nearly every day.

(5) psychomotor agitation or retardation nearly every day (observable by others, not merely subjective feelings of restlessness or being slowed down).

(6) fatigue or loss of energy nearly every day.

(7) feelings of worthlessness or excessive or inappropriate guilt (which may be delusional) nearly every day (not merely self approach about being sick).

(8) diminished ability to think or concentrate, or indecisiveness, nearly every day.

(9) recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committing suicide.

Note: These symptoms cannot be related to substance abuse (physiological effect), and the symptoms cannot be a result of bereavement (After the loss of a loved one).
