The Diagnostic and Statistical Manual of Mental Disorders (DSM) published by the American Psychiatric Association (APA) is an authoritative volume that outlines and categorizes mental disorders. When it comes to identifying depressive disorders, clinicians use the DSM to adhere to a specific criterion ensuring that a correct diagnosis is given. This article will focus on understanding the diagnostic criteria for depressive disorders as outlined in the latest edition, the DSM-5.
Understanding Depressive Disorders
Depressive disorders are characterized by significant distress or impairment in social, occupational, or other areas of functioning due to an enduring low mood, loss of interest or pleasure in activities, or both. They range in severity and type, with some of the common ones including major depressive disorder, persistent depressive disorder (dysthymia), and premenstrual dysphoric disorder.
Diagnostic Criteria for Major Depressive Disorder
Major depressive disorder is the most common depressive disorder and its diagnosis requires the presence of at least five of the following symptoms for a minimum of two weeks:
- Depressed mood most of the day, nearly every day.
- Markedly decreased interest or pleasure in all, or almost all, activities most of the day, nearly every day.
- Significant weight loss when not dieting or weight gain or decrease or increase in appetite nearly every day.
- Insomnia or hypersomnia nearly every day.
- Psychomotor agitation or retardation nearly every day.
- Fatigue or loss of energy nearly every day.
- Feelings of worthlessness or excessive guilt nearly every day.
- Diminished ability to think or concentrate, or indecisiveness, nearly every day.
- Recurrent thoughts of death, recurrent suicidal ideation without a specific plan, or a suicide attempt.
These symptoms should cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
Diagnostic Criteria for Persistent Depressive Disorder (Dysthymia)
Persistent depressive disorder is a chronic type of depression. It involves fewer symptoms than major depression, but these symptoms persist for a longer time. The symptoms persist for at least two years in adults and one year in children and adolescents. Individuals diagnosed with persistent depressive disorder must display a depressed mood for the majority of the day, for more days than not, and also display two or more of the following symptoms:
- Poor appetite or overeating.
- Insomnia or hypersomnia.
- Low energy or fatigue.
- Low self-esteem.
- Poor concentration or difficulty making decisions.
- Feelings of hopelessness.
During the two-year period of the disorder, the individual has not been without the symptoms for more than two months consecutively.
Diagnostic Criteria for Premenstrual Dysphoric Disorder
This disorder involves depressive symptoms that occur one week before menstruation and improve after menstruation starts. It is diagnosed when five or more of the following symptoms are present:
- Marked mood swings, increased sensitivity to rejection.
- Marked irritability or anger.
- Marked depressed mood, feelings of hopelessness, self-deprecating thoughts.
- Appetite changes, binge eating, or specific food cravings.
- Insomnia or hypersomnia.
- Physical symptoms such as breast tenderness or swelling, joint or muscle pain.
- Diminished concentration.
Conclusion
Depressive disorders are serious mental health disorders that affect millions of people worldwide. They are diverse in their manifestation, duration, and severity but are unified by the common theme of an abnormal depressive mood. Recognizing and understanding the diagnostic criteria for these disorders is an essential first step toward seeking help, as timely diagnosis can significantly improve the effectiveness of treatment and the long-term prognosis for the patient.
