Kleptomania

Clinical picture

• Theft is impulsive and unplanned, of low-value items the patient can easily afford and then never uses, hoards, discards, returns, or gives away.
• Mounting tension precedes the act, with pleasure, gratification, or relief at the moment of theft followed rapidly by guilt, shame, and fear of arrest.
• Patients almost never disclose spontaneously; most surface after arrest, during evaluation for depression, or when a family member forces the issue.
• Stealing occurs in stores, workplaces, and homes of acquaintances, typically alone, without accomplices, and without preparation or advance planning.
• Episodes cluster during periods of stress, loss, or depressed mood, and many patients report years of concealed behavior before any clinical contact.
• Roughly 15 years commonly separate symptom onset from first treatment contact, with legal charges preceding clinical care in most identified cases.

Criteria snapshot

• Requires repeated inability to resist impulses to steal objects that are not needed for personal use or for their monetary worth.
• Tension must rise before the theft, with pleasure, gratification, or relief experienced at the time the act is committed.
• The stealing is not done out of anger or vengeance and is not committed in response to a delusion or a hallucination.
• The behavior is not better explained by conduct disorder, a manic episode, or antisocial personality disorder.
• No symptom count or duration threshold applies; diagnosis rests on the impulse-tension-relief pattern and exclusion of ordinary shoplifting for gain.

Neurobiology

• Opioid-mediated reward signaling is implicated: naltrexone 50-150 mg/day reduced stealing urges versus placebo in a randomized controlled trial.
• Ventromedial prefrontal and inferior frontal hypofunction on imaging parallels other impulse-control disorders, impairing inhibition and outcome valuation.
• Diffusion tensor imaging has shown reduced white matter integrity in inferior frontal tracts in kleptomania compared with healthy control subjects.
• Serotonergic dysregulation is inferred from elevated impulsivity scores and shared familial loading with mood, substance use, and impulse-control disorders.
• New onset or worsening is reported after traumatic brain injury, frontal or temporal lesions, dementia, and exposure to dopamine agonists.
• First-degree relatives show elevated rates of alcohol use disorder and mood disorders, suggesting shared reward and impulse-regulation vulnerability.

Psychology

• Operant conditioning maintains the behavior: the theft terminates aversive tension, making relief a powerful and reliable negative reinforcer.
• Intermittent thrill and arousal produce highly extinction-resistant responding on a variable schedule, closely paralleling gambling behavior.
• Cognitive distortions include entitlement after perceived injustice, minimization of harm to large retailers, and the belief that stopping is impossible.
• Shame and secrecy block disclosure, and patients often present for depression or anxiety without mentioning the stealing unless asked directly.
• Affect regulation models frame theft as a self-soothing behavior recruited during loneliness, grief, boredom, or interpersonal rejection.

Differential & comorbidity

• Ordinary shoplifting is planned, motivated by the object's value or by peer influence, and lacks the tension-relief cycle that defines kleptomania.
• Rule out theft during a manic episode, psychosis-driven stealing, malingering to avoid prosecution, conduct disorder, and antisocial personality disorder.
• Comorbidity is high: mood disorders in roughly 45-60%, plus anxiety disorders, substance use disorders, and other impulse-control disorders.
• Suicidal ideation is reported by about a quarter of patients, usually tied to shame over the behavior and to legal or occupational consequences.
• Screen for bulimia nervosa, which co-occurs at markedly elevated rates, and for compulsive buying and trichotillomania in the same patients.

Pharmacologic treatment

• No agent is FDA-approved; naltrexone 50-150 mg/day has the best evidence, reducing urge intensity and stealing behavior in a controlled trial.
• Check baseline and periodic LFTs on naltrexone, confirm the patient is opioid-free for 7 to 10 days, and warn that opioid analgesia will be blocked.
• SSRIs such as fluoxetine or escitalopram treat comorbid depression and anxiety but have not outperformed placebo for the stealing itself.
• Topiramate and lithium rest on small open-label series only; reserve them for refractory cases after naltrexone and behavioral treatment fail.
• Treat comorbid bipolar disorder first, since mood stabilization markedly reduces impulsive theft that occurs inside mood episodes.

Psychotherapy

• CBT with covert sensitization pairs imagined stealing with aversive imagery such as nausea or arrest, and carries the strongest case-series support.
• Imaginal desensitization rehearses resisting the urge through to completion and outperformed covert sensitization in small controlled comparisons.
• Stimulus control restricts solo shopping, enforces cash-only purchases, and avoids high-risk stores during the early months of treatment.
• Awareness training with competing responses, borrowed from habit reversal, helps patients interrupt the automatic sequence before entering a store.
• Motivational work is essential, since most patients arrive under legal or family pressure with low intrinsic commitment to changing.

Adjunct options

• Coordinate with defense counsel and the courts; documented treatment engagement often mitigates sentencing and supports diversion programs.
• Track urges, near-misses, and episodes in a daily diary; the Kleptomania Symptom Assessment Scale quantifies change across treatment.
• Involve a partner or family member for accountability, financial oversight, and support after lapses without punitive shaming.
• Twelve-step and SMART Recovery groups adapted for behavioral addictions supply peer accountability where specialty programs are unavailable.
• Screen for and treat comorbid eating and substance use disorders, since untreated bulimia or alcohol use predicts relapse into stealing.

Clinical pearls

• Value of the item is irrelevant; patients steal what they can afford and never use.
• Naltrexone 50-150 mg/day is the best-supported pharmacotherapy; check LFTs first.
• Most cases surface only after arrest; ask about stealing directly in mood workups.
