Common questions

Why is pyromania rarely the correct clinical explanation for arson cases?+

Most fire-setting is driven by motives such as profit, revenge, concealment of another crime, or vandalism rather than the impulse-driven tension-and-release pattern the DSM-5 requires, so investigators and clinicians reserve the diagnosis for a small minority of cases.

What must be ruled out before diagnosing pyromania?+

The DSM-5 criteria exclude fire-setting done for monetary gain, to express anger or vengeance, as a result of impaired judgement from intoxication or psychosis, or as a symptom of conduct disorder, mania, or antisocial personality disorder.

Does a pyromania diagnosis affect criminal culpability?+

A diagnosis does not automatically establish a legal insanity or diminished-capacity defence. Courts assess criminal responsibility separately against jurisdiction-specific legal tests, and a clinical diagnosis is only one piece of evidence considered.
