Description
Depression is a condition characterized by an extended period of low mood, anhedonia, and reduction in activity. It is thought to be experienced by between 3 and 7 people out of every 100 (Kessler et al, 2005).
The DSM-5 diagnostic criteria for a major depressive episode include:
- Feeling depressed most of the day, nearly every day, or having a markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day.
- Four additional symptoms from:
- Significant weight loss or gain, with a decreased or increased appetite
- Insomnia or hypersomnia
- Psychomotor agitation or retardation
- Fatigue or loss of energy
- Feelings of worthlessness, or excessive or inappropriate guilt
- Diminished ability to think or concentrate, or indecisiveness
- Recurrent thoughts of death, including recurrent suicidal ideation, a suicide attempt, or a specific plan for committing suicide
The ICD-11 diagnostic criteria for a depressive episode include:
- A period of depressed mood or diminished interest in activities, occurring most of the day and nearly every day during a period of at least two weeks.
