What are three core symptoms of depression?

The selection of low mood, lack of energy, and failure to enjoy things as core symptoms of depression is grounded in established psychological frameworks. These three symptoms are widely recognized as key indicators of major depressive disorder.

Low mood, or persistent sadness, is fundamental to depression, distinguishing it from temporary feelings of sadness or sorrow. It affects an individual's overall outlook on life and can impair daily functioning.

Lack of energy, often described as fatigue or physical lethargy, is another hallmark of depression. Individuals may experience overwhelming tiredness that is not alleviated by rest, which can further hinder their ability to engage in everyday activities or social interactions.

The failure to enjoy things, also known as anhedonia, refers to a significant decrease in interest or pleasure in activities that were once found enjoyable. This symptom can lead to withdrawal from social situations and a decline in motivation, significantly impacting one's quality of life.

In contrast, the other symptoms listed in the other options do not align with the diagnostic criteria for depression. Some may reflect anxiety or other mood disorders but do not encompass the core symptoms typically associated with depression.
