What constitutes a diagnosis of depression based on symptom criteria?

A diagnosis of depression, specifically Major Depressive Disorder, is defined by experiencing a specific number of symptoms for a certain duration of time. According to established diagnostic criteria, a key component for diagnosing depression is the presence of five or more symptoms that significantly impair daily functioning, lasting for at least two weeks. This timeframe emphasizes that the symptoms are not just transient or tied to a momentary state but instead indicate a more severe and persistent mental health condition.

The criteria highlight that the number of symptoms and the duration are critical for establishing a clinical diagnosis, which is why experiencing five symptoms for two weeks is the correct framework. This ensures that the condition is not mistaken for temporary feelings of sadness or distress that many individuals encounter in daily life.

Other options fail to meet the recognized diagnostic criteria; for example, requiring five symptoms over six months or three symptoms for one month do not align with the standard two-week duration needed for diagnosing depressive disorders. Similarly, reporting symptoms just twice a year does not reflect the consistent symptomatology necessary for a diagnosis, which is aimed at distinguishing clinical depression from more fleeting or sporadic emotional challenges.
