Dysthymia is characterized by which of the following?

Dysthymia, also known as persistent depressive disorder, is characterized by a chronic state of depression lasting for at least two years in adults (or at least one year in children and adolescents). Individuals with dysthymia often experience anhedonia, which refers to a loss of interest or pleasure in activities that were previously enjoyable. Additionally, they typically display sustained feelings of sadness, hopelessness, and a reduction in energy levels throughout this prolonged episode of depression.

The nature of dysthymia distinguishes it from more acute depressive episodes, highlighting the persistent and enduring quality of the depressive symptoms rather than episodic occurrences. This chronic presentation can interfere significantly with daily functioning and quality of life.

In contrast, the other choices suggest states or symptoms that do not align with the core characteristics of dysthymia. For example, euphoria and weight gain are not typically associated with this form of depression, while irregular sleep patterns can vary greatly among depressive disorders but are not defining features of dysthymia specifically. Hyperactivity and impulsivity relate more closely to conditions such as bipolar disorder or attention-deficit hyperactivity disorder, rather than dysthymia.
