The diagnosis that is characterized by depressive symptoms resulting in significant distress or impairment in functioning is Major Depressive Disorder. This disorder is defined by the presence of a depressed mood or loss of interest or pleasure in nearly all activities, lasting for at least two weeks. It encompasses a range of symptoms that severely affect daily functioning, including significant changes in weight, sleep disturbances, fatigue, feelings of worthlessness, and recurrent thoughts of death or suicide.

While Persistent Depressive Disorder also involves depressive symptoms, it is more chronic and includes a duration of at least two years, making it distinct in terms of time rather than the presence of impairment. Adjustment Disorder with Depressed Mood refers to depressive symptoms in response to a specific stressor, occurring within three months of the stressor, and typically involves less severity and duration compared to Major Depressive Disorder. Acute Stress Disorder is related to exposure to a traumatic event and includes symptoms of re-experiencing, avoidance, and hyper-arousal, rather than major depressive symptoms.

Major Depressive Disorder distinctly highlights the severity and pervasiveness of depressive symptoms that result in impairment, which is why it is recognized as a critical diagnosis within the DSM-V.
