Psychiatry: Impulse Control Disorders
Failure to Resist Urges
Impulse Control Disorders (ICDs) are characterized by the failure to resist an impulse, drive, or temptation to perform an act that is harmful to oneself or others.
1. Classic ICDs
- Kleptomania: Recurrent failure to resist impulses to steal objects not needed for personal use or monetary value.
- Pyromania: Deliberate and purposeful fire-setting on more than one occasion, accompanied by tension/arousal before the act.
- Intermittent Explosive Disorder (IED): Recurrent behavioral outbursts representing a failure to control aggressive impulses.
- Trichotillomania: Recurrent pulling out of one’s own hair, resulting in hair loss.
2. The “Impulse Cycle.”
| Stage | Clinical Description |
|---|---|
| 1. Tension | Rising internal pressure or anxiety before the act. |
| 2. The Act | Performance of the impulsive behavior. |
| 3. Relief/Pleasure | Gratification or release of tension experienced during/immediately after. |
| 4. Guilt/Remorse | Self-reproach or regret follows the act (not universal in all types). |
3. NEET PG High-Yield Pearls
- Forensic Link: Individuals with IED or pyromania often come into contact with the law. Assessment of criminal responsibility depends on whether the impulse was truly “irresistible” or if the individual retained the capacity to appreciate the wrongfulness of the act.
- Treatment: Often involves Cognitive Behavioral Therapy (CBT) and SSRIs, though treatment efficacy for some conditions, like pyromania, remains difficult.
- Comorbidity: Frequently comorbid with substance use disorders, mood disorders, and anxiety disorders.
