Depressive Disorder: Type I Mood Disorders

Glad you are back and enjoying my articles. In the last article, we talked about Mood Disorders and how Bipolar Disorder was one of them. Now, we are going to talk about type one mood disorders. Type one Mood Disorders are those in which the person experiences only episodes of depression, known as depressive disorders.


Please pay close attention to what I am going to say next. An individual may exhibit depression as a mood or as a clinical syndrome, which is characterized by emotional, cognitive, and behavioral symptoms. Depressed moods are often characterized by disappointment and despair. Though sadness is universal, deep depression is not. One experience shades gradually into the next. Depressed people describe the feeling as overwhelming, suffocating, or numbing. The syndrome of depression, also known as clinical depression, is characterized by a depressed mood and other symptoms, such as fatigue, a lack of energy, trouble sleeping, and changes in appetite. Clinical depression also involves a variety of behavioral and mental changes.


There are three main types of depressive disorders. The first is called major depressive disorder (MDD). To meet the criteria for MDD, a person must experience at least one major depressive episode without any history of manic episodes. While some people experience an isolated episode of MDD followed by full recovery, most people experience intermittent episodes of depression.


The second main type of depressive disorder is a persistent depressive disorder known as dysthymia, which differs from MDD in terms of severity and duration. Persistent depressive disorder represents a chronic mild depressive condition that has been present for many years. To fulfill DSM-5 criteria for this disorder, the person must exhibit a depressed mood for most of the day on more days than not over a period of at least two years. Two or more of the following symptoms must also be present:

  • Poor appetite or overeating

  • Insomnia or hypersomnia

  • Low energy or fatigue

  • Low self-esteem

  • Poor concentration or difficulty making decisions

  • Feelings of hopelessness

The third is called a premenstrual dysphoric disorder. Premenstrual dysphoric disorder (PMDD) is defined as various mood-related symptoms that repeatedly occur during the premenstrual phase of the cycle and are then diminished at the onset or shortly after menses. Symptoms include mood lability, irritability, dysphoria, anxiety, and cognitive and somatic symptoms. For this disorder to be diagnosed, a woman must exhibit at least five of these symptoms, and at least one of those symptoms must involve a disturbance mood like mood swings. The symptoms must have been present for most of the woman’s menstrual cycles in the past year. They must be associated with clinically significant distress or interference with social or occupational functioning.


Now there is a fourth type that is not as common, called disruptive mood dysregulation disorder, and it is used to describe children with chronic, severe irritability.


So to recap what we just learned, there are, in total, four types of Depressive Disorders:

  • Major depressive disorder (MDD)

  • Persistent depressive disorder (dysthymia)

  • Premenstrual dysphoric disorder (PMDD)

  • Disruptive mood dysregulation disorder
