Which of the following is NOT a common symptom of depression?

In the context of depression, increased energy is not typically identified as a common symptom. Depression is characterized by a variety of symptoms that often involve diminished mood, motivation, and emotional well-being. For instance, persistent sadness often manifests as a prolonged feeling of hopelessness or despair, which is fundamental to the depressive experience.

Loss of interest in activities, also known as anhedonia, is a hallmark symptom of depression where individuals find themselves disengaged from previously enjoyed activities. Similarly, changes in appetite, which can include significant weight loss or gain, are frequently observed as changes in eating habits often correlate with mood fluctuations.

In contrast, increased energy is generally not associated with depression, as it is more often linked to elevated mood states or manic episodes in conditions such as bipolar disorder. Understanding these distinctions is crucial for recognizing and diagnosing depression accurately.
