Which of the following is indicative of affective disorders?

Affective disorders, commonly referred to as mood disorders, primarily involve significant disturbances in a person's mood. This can manifest as extreme feelings of sadness, hopelessness, or anxiety, among others. Therefore, a disturbance of mood is a foundational characteristic of affective disorders. This element directly relates to the emotional state of the individual, demonstrating how affective disorders can alter one's perception and reaction to experiences.

Hyperactivity and extreme energy levels might be seen in other psychological conditions, such as attention-deficit hyperactivity disorder (ADHD) or certain episodes of bipolar disorder, but they do not encompass the broad spectrum of affective disorders. Physical symptoms without emotional impact could indicate other medical or psychological issues but do not reflect the core aspect of mood disturbance inherent in affective disorders. Thus, the identification of mood disturbances as a hallmark of affective disorders highlights their central role in understanding this type of mental health condition.
