Depressive disorders are mental health conditions that negatively affect a person's mood, thinking patterns, and physical health, usually persisting over a long period and in a widespread way. Depression can adversely affect daily life and often lead to loss of functioning. These disorders can reduce overall quality of life and, in severe cases, increase suicide risk.
Depressive disorders can occur in different types and degrees of severity. Some common forms of depression include:
- Major Depressive Disorder: Characterised by prominent symptoms that meaningfully affect everyday life. Signs may include sleep disturbance, loss of energy, loss of interest, concentration difficulties, feelings of worthlessness, and suicidal thoughts.
- Dysthymia (Persistent Depressive Disorder): A form of depression that is less prominent than major depression but longer lasting. The person experiences persistently low energy, low self-esteem, and hopelessness for at least two years.
- Bipolar Disorder: A condition in which the person experiences alternating periods of mania (excessive energy and elevated mood) and depression (low energy and low mood) over time.
- Seasonal Affective Disorder: A type of depression associated with seasonal changes, often linked to reduced light exposure during winter months.
- Anxiety and Depressive Disorders: Depression is frequently seen together with anxiety disorders.
Depressive disorders usually have a complex aetiology, and a combination of biological, genetic, environmental, and psychosocial factors may play a role. Treatment often includes psychotherapy and/or medication. It is extremely important for people showing these symptoms to seek specialist help, as these conditions can be managed with professional support.
