What best describes pyromania?

Pyromania is best described as an impulse-control disorder involving an irresistible urge to set fires. This disorder is characterized by a fascination with fire and a compulsion to deliberately ignite it, often resulting in significant distress or impairment in functioning. Individuals with pyromania may not only enjoy the act of setting fires but also experience a sense of relief or gratification afterward.

In contrast, the other options do not accurately represent pyromania. Anxiety disorders are primarily about excessive worrying and do not encompass the impulsive fire-setting behavior characteristic of pyromania. Similarly, personality disorders, which involve enduring patterns of behavior, emotion, and inner experience, do not align with the specific and compulsive nature of pyromania. Lastly, affective disorders focus on mood disturbances, such as extreme highs and lows, and do not relate to the impulsive and destructive actions associated with setting fires. Thus, the defining features of pyromania clearly categorize it as an impulse-control disorder.
