Which type of mental health disorder includes common and severe forms?

Mood disorders encompass a range of conditions characterized by significant alterations in mood, including both common forms like depression and bipolar disorder, which can manifest in severe episodes. These disorders affect a person's emotional state and can lead to substantial impairment in daily functioning. Common mood disorders include major depressive disorder, which is widespread, and bipolar disorder, which includes episodes of mania and depression.

The classification of mood disorders highlights their prevalence and severity. While other types of disorders, such as anxiety disorders, personality disorders, and psychotic disorders, also present with various symptoms and levels of impact, mood disorders are particularly notable for their significant effects on an individual’s overall well-being and quality of life. The commonality of mood disorders, coupled with their ability to escalate into severe forms, underscores their relevance in mental health discussions.
