Mood disorders are mental health issues which primarily affect a person’s emotional wellbeing through long periods of extreme happiness, sadness, or a combination of both. In general, mood changes are considered to be normal. However, when symptoms become persistent for several weeks or months, a mood disorder may be diagnosed. Mood disorders may cause behavioural changes, and at times may also affect a person’s ability to deal with day-to-day activities such as work and school.
Mood Disorders feature a change in mood (sustained emotional attitude) or affect (others’ perception of the person’s emotional state). This change is usually accompanied by a change in the overall activity level of the person, along with other symptoms secondary to or relevant to the said change. This period tends to be recurrent, with the onset of each individual episode being triggered by neurobiological or psychosocial factors.
