A kleptomaniac is someone with kleptomania, a recognized mental health condition characterized by repeated, powerful urges to steal items they don’t need and often can’t even use. Unlike ordinary theft, the stealing isn’t motivated by want, profit, or rebellion. People with kleptomania steal because the impulse feels impossible to resist, and they typically feel intense guilt, shame, and self-loathing afterward.
How Kleptomania Differs From Shoplifting
The distinction between kleptomania and regular shoplifting comes down to motivation and emotional experience. A shoplifter generally steals for a reason: they want the item, they can’t afford it, or they’re doing it for a thrill. A person with kleptomania often steals things that have no value to them and that they could easily afford. The stolen objects frequently end up hidden away, given away, or thrown out.
That said, the line is blurrier than textbooks suggest. A comparative study of kleptomaniacs and shoplifters found that roughly one in five shoplifters also reported not stealing the item for personal use and discarding it later. Both groups also rated fairly high on impulsivity. The key difference was in the emotional cycle: kleptomaniacs reported significantly more inner tension before the theft and a stronger sense of relief during it. That tension-and-release pattern is the hallmark of the condition, and it’s what makes kleptomania feel more like an addiction than a choice.
The Tension-Relief Cycle
Kleptomania follows a predictable emotional loop. First comes a rising sense of tension or anxiety that builds until it becomes difficult to ignore. Then comes the act of stealing, which brings a brief wave of relief or even pleasure. Almost immediately afterward, the person is flooded with guilt, shame, fear of being caught, and self-loathing. This cycle can repeat for years. The urges may come and go, sometimes intensifying during periods of stress, and sometimes fading for weeks or months before returning.
People with kleptomania are not “getting away with something” in any satisfying sense. Most describe the experience as distressing and bewildering. They know the stealing is wrong, they don’t want the items, and they can’t explain why they keep doing it.
What Happens in the Brain
Kleptomania involves at least three brain chemical systems working abnormally together. The reward system, driven largely by dopamine, appears to be overactive. One striking piece of evidence: some people with Parkinson’s disease develop kleptomania as a side effect of dopamine-boosting medications. Their motor symptoms improve, but the extra dopamine overstimulates the brain’s reward and impulse pathways, triggering compulsive behaviors like stealing, gambling, or binge eating.
Serotonin, which helps regulate mood and impulse control, also plays a role. Low serotonin activity is linked to difficulty resisting urges. Paradoxically, some people have developed kleptomania symptoms shortly after starting antidepressants that raise serotonin levels, possibly because of temporary disruptions in how the brain adjusts to the medication.
The opioid system, the same network involved in addiction and physical pleasure, rounds out the picture. Kleptomania shares features with substance use disorders: the craving, the temporary high, the inability to stop despite consequences. This overlap is why medications originally developed for addiction have shown promise in treating the condition.
Who Develops Kleptomania
Kleptomania typically begins in adolescence or early adulthood. Males tend to develop it at a slightly younger age, but roughly two-thirds to four-fifths of diagnosed patients are women. That gender gap may be partly an artifact of how the legal system works: women caught stealing are more likely to be referred to psychiatric evaluation, while men are more likely to be processed through the criminal justice system. Some researchers believe the actual rates between men and women are closer to equal.
Kleptomania occurs across all income levels and social classes. It has nothing to do with poverty or financial need.
Conditions That Often Occur Alongside It
Kleptomania rarely shows up alone. In one study of 20 patients with the disorder, every single one had a lifetime history of depression. Sixteen of the 20 had been diagnosed with an anxiety disorder, and 12 had an eating disorder. Substance use disorders, particularly involving alcohol and nicotine, are also common.
This pattern of overlapping conditions suggests kleptomania is part of a broader difficulty with impulse regulation and mood control rather than an isolated quirk. The depression and anxiety may fuel the tension that precedes stealing episodes, creating a feedback loop where emotional distress drives the compulsive behavior and the behavior deepens the distress.
How Kleptomania Is Treated
Treatment typically combines therapy and, in some cases, medication. The most widely used therapeutic approach is cognitive behavioral therapy, which includes techniques like covert sensitization (learning to associate the urge to steal with an unpleasant mental image), relaxation training to manage the tension that precedes episodes, and developing alternative sources of satisfaction to replace the relief that stealing provides.
On the medication side, one of the more promising options works by blocking the brain’s opioid receptors, essentially dampening the “high” that makes the stealing cycle self-reinforcing. In a study of 10 patients treated over 11 weeks, seven were rated “very much improved” and two more “much improved.” Participants reported significant reductions in both the urge to steal and actual stealing behavior, along with better social and work functioning. Notably, half of the participants had previously tried other medications and therapy without success, so this represented a breakthrough for them. Nausea during the first week was the most common side effect.
Treatment works, but the biggest barrier is that most people with kleptomania never seek help. Shame keeps them quiet, and fear of legal consequences makes them reluctant to disclose the behavior even to a therapist.
Kleptomania and the Legal System
Having kleptomania does not exempt someone from criminal charges. Courts have consistently held that a psychiatric diagnosis alone is not enough to excuse theft. The core legal challenge is proving that the behavior was truly uncontrollable rather than simply uncontrolled, a distinction that’s difficult to establish in a courtroom.
That said, the legal system does offer some pathways that account for the disorder. Under federal sentencing guidelines, a reduction in sentencing may be available to someone who understood that stealing was wrong but genuinely could not control the impulse. Some jurisdictions also offer diversion into mental health courts or therapeutic programs instead of standard prosecution, an approach that addresses the underlying condition rather than cycling someone through repeated arrests and jail time.
