pyromania
Pyromania is an impulse control disorder in which individuals repeatedly fail to resist impulses to deliberately start fires,[1] to relieve some tension or for instant gratification. The term pyromania comes from the Greek word πῦρ (pyr, 'fire'). Pyromania is distinct from arson, the deliberate setting of fires for personal, monetary or political gain.[2] Pyromaniacs start fires to release anxiety and tension, or for arousal.[3] Other impulse disorders include kleptomania and intermittent explosive disorder.
