Kleptomania is a chronic, under-recognized Impulse-control disorder defined by recurrent failure to resist urges to steal objects not needed for personal use or monetary value, with mounting tension before the act and relief or pleasure during it. DSM-5-TR classifies it within Disruptive, Impulse-Control, and Conduct Disorders; ICD-11 places it in chapter 06 under Impulse Control Disorders (6C71). Patients typically present not to psychiatry first but to courts, retailers, or primary care after legal contact, and the diagnosis is missed when clinicians equate any shoplifting with ordinary theft. The two most clinically useful facts about kleptomania are its high psychiatric comorbidity — particularly mood disorders, anxiety disorders, substance use disorders, and other impulse-control conditions — and the modest but real evidence base supporting naltrexone as the only pharmacotherapy with a positive randomized controlled trial. Behavioral interventions, particularly covert sensitization and imaginal desensitization, are first-line non-pharmacologic options. The bottom line: ask about stealing, look for the urge-tension-relief cycle, screen for comorbidity, and offer naltrexone plus CBT when the diagnosis is made.

Kleptomania is rare in the general population but markedly enriched in forensic and shoplifter samples. Estimated lifetime prevalence in the general population is roughly 0.3 to 0.6 percent, with clinical samples consistently showing a female-to-male ratio of approximately 2:1.^3,5

Prevalence and demographics

• Lifetime prevalence in community samples is estimated at 0.3 to 0.6 percent, though no large epidemiologic study has measured kleptomania directly with a structured interview.^3,5
• The broader category of impulse-control disorders had a 12-month prevalence of 8.9 percent in the National Comorbidity Survey Replication, but that figure aggregates intermittent explosive disorder, conduct disorder, ODD, and ADHD rather than isolating kleptomania.²
• Among apprehended shoplifters, the proportion meeting DSM criteria for kleptomania is substantially higher than in the general population, with case-series estimates ranging from roughly 4 to 24 percent.⁵
• Clinical samples consistently report female predominance of approximately 2:1, with mean age of onset in late adolescence, around 16 years, though onset across the lifespan is reported.^1,3

Comorbidity

• Lifetime psychiatric comorbidity is the rule, not the exception. In a series of 22 patients, 77.3 percent met criteria for at least one lifetime Axis I disorder beyond kleptomania.¹
• Mood disorders are the most common comorbid conditions, with lifetime rates reported between 45 and 100 percent across case series.^1,3
• Other impulse-control disorders co-occur in 20 to 46 percent and substance use disorders in 23 to 50 percent across published samples.^3,9
• Anxiety disorders, eating disorders (particularly bulimia nervosa), and obsessive-compulsive disorder are also overrepresented relative to base rates.^1,3
• First-degree relatives of patients with kleptomania show elevated rates of substance use disorders, supporting a familial link with the addictive end of the impulse-compulsive spectrum.^4,9

Risk factors

• Female sex, family history of substance use or mood disorder, and adolescent or early-adult onset of impulsive behaviors are the most consistently cited risk markers.^3-4
• Childhood adversity and head injury have been described in case reports but are not established population-level risk factors.⁵

Kleptomania is widely conceptualized as a behavioral addiction with phenomenologic and neurobiologic overlap with substance use disorders, mood disorders, and obsessive-compulsive spectrum conditions. No single model fully accounts for the disorder, and the evidence base is small.^4-5,12

Neurobiology

• The endogenous opioid system has been implicated in the reward and relief that follow stealing, and is the mechanistic rationale for opioid-antagonist treatment with naltrexone.^6,10
• Serotonergic dysregulation has been proposed by analogy to obsessive-compulsive and impulse-control phenomena, though SSRI trials in kleptomania have been negative or inconclusive.^5,7
• A pilot diffusion-tensor imaging study in 10 women with kleptomania found decreased fractional anisotropy in inferior frontal white matter tracts, consistent with reduced top-down inhibitory control.⁸
• Impulsivity in kleptomania, as in other impulse-control disorders, is conceptualized in terms of fronto-striatal circuit dysfunction affecting response inhibition and reward processing.¹²

Psychological and behavioral models

• Operant models frame stealing as negatively reinforced by relief from a rising aversive tension state and positively reinforced by the affective release that follows the act.⁴
• Cognitive models emphasize maladaptive beliefs (entitlement, justification, minimization) and deficits in distress tolerance and emotion regulation.^3-4
• The behavioral-addiction framework groups kleptomania with pathological gambling and other non-substance addictions, sharing features of craving, loss of control, and continuation despite consequences.¹²

Genetics and family studies

• Formal twin and molecular genetic studies in kleptomania are lacking; family-history data show elevated rates of substance use disorders among first-degree relatives.^4,9

DSM-5-TR places kleptomania within Disruptive, Impulse-Control, and Conduct Disorders. The diagnosis requires a recurrent pattern of stealing that is not motivated by need, anger, or delusion, and is not better accounted for by another disorder.¹³

DSM-5-TR criteria, summarized

• Recurrent failure to resist impulses to steal objects that are not needed for personal use or for their monetary value.¹³
• An increasing sense of tension immediately before committing the theft.¹³
• Pleasure, gratification, or relief at the time of committing the theft.¹³
• The stealing is not committed to express anger or vengeance and is not in response to a delusion or hallucination.¹³
• The stealing is not better explained by conduct disorder, a manic episode, or antisocial personality disorder.¹³

ICD-11 placement

• ICD-11 lists kleptomania under Impulse Control Disorders (code 6C71), aligning closely with the DSM-5-TR criteria and emphasizing the repetitive failure to resist stealing impulses despite negative consequences.¹⁴
• ICD-11 uses a dimensional impulse-control framework but does not add specifiers for kleptomania.¹⁴

Diagnostic pitfalls

• Patients often minimize or rationalize stealing; clinicians must ask explicitly about the urge-tension-relief cycle rather than about theft alone.^3,5
• The exclusion for anger or vengeance is meaningful: stealing motivated by revenge against a partner or employer is not kleptomania.¹³
• Stealing during a manic or psychotic episode is excluded; the diagnosis requires that episodes occur outside such states.¹³

The prototypical kleptomania episode is brief, premeditated only in the sense that the patient anticipates the urge, and centered on items the patient does not need. The objects are often hoarded, hidden, given away, or returned, and patients report shame, anxiety, and depressive symptoms between episodes.^1,3-4

Core symptom cycle

• Rising tension or arousal in the minutes to hours before the act, sometimes triggered by stress, dysphoria, or the sight of an opportunity.^1,4
• Pleasure, gratification, or relief at the moment of the theft, often described as similar to a craving satisfied.^3-4
• Post-theft guilt, shame, fear of apprehension, and dysphoria that frequently precipitate further depressive symptoms.^1,3

Behavioral phenomenology

• Items stolen are typically inexpensive and not needed; patients commonly have the money to pay for them and often discard, return, or give them away.^1,3
• Stealing usually occurs alone, from retail stores most commonly, but also from acquaintances, workplaces, and homes.^1,3
• Frequency varies widely, from less than once a month to multiple times per day, and many patients describe periods of relative abstinence punctuated by relapse.^1,3
• Mean reported duration of illness before treatment is many years, often more than a decade, reflecting late presentation and high secrecy.^1,3

Atypical and red-flag presentations

• New-onset stealing in a previously well older adult should prompt a workup for neurocognitive disorder, frontal lobe pathology, or medication effect (including dopamine-agonist therapy in Parkinson disease).⁵
• Stealing in the context of a manic episode, psychotic disorder, or substance intoxication is not kleptomania and points instead to the primary disorder.¹³
• Co-occurring suicidal ideation is common given the high mood-disorder comorbidity and the secondary depression that follows legal or interpersonal consequences.^1,3

Most stealing is not kleptomania. The clinical task is to distinguish recurrent non-acquisitive theft driven by the urge-tension-relief cycle from theft motivated by need, antisocial gain, a primary psychiatric or neurologic state, or a substance.^3,5,13

Ordinary or antisocial theft

• Theft for monetary gain, peer approval, or as part of a broader pattern of rule-violating behavior is the most common alternative and is not kleptomania.¹³
• A diagnosis of antisocial personality disorder or conduct disorder generally precludes kleptomania when stealing fits the broader pattern.¹³

Mood disorders

• Stealing during a manic or hypomanic episode reflects bipolar disorder, not kleptomania, particularly when accompanied by grandiosity or disinhibition.¹³
• Depressive disorders frequently coexist with kleptomania and require independent diagnosis and treatment.^1,3

Psychotic and neurocognitive disorders

• Stealing driven by a delusion (for example, the belief that an item is rightfully owned) is excluded from kleptomania.¹³
• Major or mild neurocognitive disorder, particularly behavioral-variant frontotemporal dementia, can present with new-onset shoplifting and disinhibition and should be considered in older patients with no prior psychiatric history.⁵

Substance-related and medication-induced presentations

• Theft to obtain money for substances is not kleptomania; the act is acquisitive.¹³
• Dopamine-agonist therapy in Parkinson disease and restless legs syndrome has been associated with impulse-control symptoms, including pathological stealing in case reports, and should be reviewed at presentation.⁵

Other impulse-control and OCD-spectrum disorders

• Compulsive shopping or hoarding can co-occur but is distinguished by acquisition through purchase or by the meaning of the saved item rather than the act of stealing.⁵
• Pathological gambling and trichotillomania share the urge-relief cycle but differ in the target behavior.¹²

Malingering and factitious presentations

• A claim of kleptomania after apprehension, in the absence of the characteristic urge-tension-relief cycle, prior secrecy, and shame between episodes, raises concern for malingering, especially when secondary gain is obvious.^3,5

Assessment hinges on direct, non-judgmental questioning about stealing, since most patients will not volunteer the behavior. The diagnostic interview should establish the urge-tension-relief cycle, exclude alternative explanations, and screen aggressively for comorbidity.^3,5

Interview approach

• Frame stealing questions matter-of-factly within an impulse-control review, alongside gambling, compulsive shopping, hair pulling, and skin picking, to reduce shame and increase disclosure.^3,5
• Probe for the characteristic cycle directly: tension before, relief or pleasure during, dysphoria or shame after.^1,3
• Ask what was stolen, what happened to the items afterward, and whether the patient could have paid; non-acquisitive theft of unneeded items is the signature.^1,3
• Establish age of onset, frequency, longest abstinent interval, and consequences (legal, occupational, interpersonal).^1,3

Required history elements

• Full mood-disorder history, including suicidal ideation and prior attempts, given high comorbidity.^1,3
• Substance use history, with attention to alcohol and stimulants.⁹
• Screen for other impulse-control and OCD-spectrum disorders, eating disorders (especially bulimia nervosa), and ADHD.^1,3
• Forensic history, including prior arrests, current charges, and probation status, which affect treatment planning and confidentiality boundaries.^3,5

Physical and cognitive exam

• Cognitive screening in older patients or those with new-onset behavior; bedside testing of frontal-executive function with instruments such as the Frontal Assessment Battery can flag frontotemporal pathology.⁵
• Review current medications, especially dopamine agonists and stimulants, which can disinhibit impulse-control behaviors.⁵

Rating scales

• The Kleptomania Symptom Assessment Scale (K-SAS), an 11-item self-report measure, tracks urge intensity, frequency, and impairment and was used as a primary outcome in the naltrexone RCT.⁶
• The Yale-Brown Obsessive Compulsive Scale modified for kleptomania (K-YBOCS) measures the obsessive and compulsive dimensions of stealing urges and behavior.⁶
• Generic comorbidity scales — PHQ-9 for depression, GAD-7 for anxiety, AUDIT for alcohol use — should be administered at baseline given the comorbidity burden.³

Laboratory and imaging

• No laboratory or imaging finding is diagnostic of kleptomania; investigations are driven by differential diagnosis (thyroid, metabolic panel, neuroimaging when neurocognitive disorder is suspected).⁵
• Routine neuroimaging is not recommended for typical presentations.⁵

No medication is FDA-approved for kleptomania, and the overall evidence base is limited to one positive randomized controlled trial, open-label series, and case reports. Treatment is best framed as combining a behavioral or cognitive-behavioral intervention with pharmacotherapy directed at the urge-tension-relief cycle and at comorbid disorders.^5,7

Pharmacotherapy

• Naltrexone is the only medication with a positive randomized controlled trial in kleptomania. An 8-week double-blind, placebo-controlled trial in 25 patients found that flexibly dosed naltrexone (mean dose approximately 117 mg/day) significantly reduced stealing urges, stealing behavior, and K-YBOCS scores relative to placebo.⁶
• A systematic review of pharmacotherapy for impulse-control disorders concluded that naltrexone is the only agent with replicated positive controlled-trial evidence in kleptomania.⁷
• SSRIs (notably fluoxetine and fluvoxamine) have been studied in small open-label and placebo-controlled samples; results are mixed and they are not first-line for kleptomania itself, though they remain reasonable for comorbid depressive or anxiety disorders.^5,7
• Mood stabilizers (lithium, valproate, topiramate) have been described in case reports and small open trials; evidence is too limited to recommend as monotherapy for kleptomania.^5,7
• An open-label pilot study of memantine 10 to 30 mg/day in 12 patients reported reductions in stealing behavior and impulsivity, but this remains preliminary and unreplicated.¹¹

Psychotherapy

• Cognitive-behavioral therapy is the most studied psychological treatment; specific techniques with the strongest support are covert sensitization, imaginal desensitization, and aversion therapy, generally delivered over 8 to 12 sessions.^4-5,10
• Covert sensitization pairs imagined stealing with imagined aversive consequences (apprehension, shame, family discovery) to reduce the appetitive value of the urge.^4,10
• Imaginal desensitization teaches patients to vividly imagine the stealing cue, tolerate the rising urge, and rehearse competing non-stealing responses to extinction.^4,10
• Stimulus-control strategies (avoiding solo shopping in high-risk stores, carrying limited cash, shopping with a companion) reduce opportunity and craving exposure.⁴
• Treatment of comorbid depression, anxiety, substance use, and eating disorders should proceed in parallel and may reduce stealing indirectly by improving distress tolerance.^1,3

Neuromodulation

• There is no established role for ECT, rTMS, or other neuromodulation in kleptomania; a systematic review of pharmacotherapy for impulse-control disorders identified no controlled trials of neuromodulation in this population.⁷

Adjunctive

• Twelve-step and self-help groups (notably Cleptomaniacs and Shoplifters Anonymous) are accessible and may support recovery, though they have not been studied in controlled trials.⁵
• Family education and involvement, when appropriate, can reduce secrecy and support relapse prevention.^3,5
• Legal and forensic considerations (probation, court-mandated treatment) frequently shape the treatment frame and should be discussed openly with the patient at intake.^3,5

The harms picture in kleptomania is driven less by treatment-emergent adverse effects than by the consequences of untreated illness — legal exposure, occupational loss, depression, and suicide risk. The evidence base for every available treatment is small and short.^5,7

Treatment-related harms

• Naltrexone is associated with nausea (common at initiation), dose-related transaminase elevation, and headache; it precipitates withdrawal in opioid-dependent patients and blocks opioid analgesia.^6-7
• SSRIs carry the usual class adverse-effect profile (GI upset, sexual dysfunction, activation, discontinuation symptoms) without clear efficacy for stealing behavior itself.⁷
• Mood stabilizer trials are too small to characterize harms specific to the kleptomania population beyond class effects.⁷

Harms of untreated illness

• Legal consequences (arrest, prosecution, incarceration) are common and frequently the precipitant for treatment-seeking.^3,5
• Occupational and interpersonal losses, secondary depression, and elevated suicide risk in patients with comorbid mood disorder are described across clinical samples.^1,3

Limitations of the evidence base

• Only one randomized controlled trial has been completed in kleptomania, with 25 participants over 8 weeks; long-term effectiveness and relapse data are essentially absent.^6-7
• Samples are predominantly female, treatment-seeking, and recruited through media advertising, limiting generalizability to forensic, male, and non-treatment-seeking populations.^1,3
• Publication bias toward positive case reports likely overstates the benefits of agents that have not been tested in controlled trials.⁷
• No comparative-effectiveness trials of naltrexone versus CBT, or of combined versus monotherapy strategies, exist.⁷

Treatment must be adapted to context. The clinically distinct groups are adolescents, older adults, perinatal patients, and those with significant medical or substance use comorbidity.^3,5

Pediatric and adolescent

• Onset in adolescence is the modal pattern, and adolescents are more likely to present after caught stealing rather than self-referral.^1,3
• Differential diagnosis must distinguish kleptomania from conduct disorder; the urge-tension-relief cycle and the non-acquisitive nature of stolen items are the key features.¹³
• No medication is FDA-approved for kleptomania at any age; naltrexone use in adolescents has been reported in case series with cautious dosing.⁵

Geriatric

• New-onset stealing in older adults raises concern for frontotemporal dementia or other neurocognitive disorders and warrants cognitive screening and consideration of neuroimaging.⁵
• Medication review is essential, with particular attention to dopamine agonists, which have been associated with impulse-control symptoms.⁵

Perinatal

• Case reports describe onset or exacerbation of kleptomania during pregnancy and the postpartum period, often in association with mood symptoms; treatment decisions balance the limited efficacy data against the maternal-fetal risk profile of available agents.⁵
• Naltrexone is FDA pregnancy category C with limited human data; SSRIs are better characterized in pregnancy and may be preferred when comorbid depression is the driver.⁵

Comorbid substance use

• Approximately one-quarter to one-half of patients with kleptomania have a lifetime substance use disorder, and treatment of the substance use disorder is typically prioritized.⁹
• Naltrexone is attractive in patients with comorbid alcohol use disorder given its independent indication for alcohol use disorder, but is contraindicated with current opioid use.^6,9

Forensic

• Court-mandated treatment is common; clinicians should clarify the limits of confidentiality, the reporting obligations to the court, and the difference between psychiatric treatment and forensic evaluation at the first visit.^3,5

Kleptomania is a chronic relapsing-remitting condition, with most patients reporting symptoms for years to decades before diagnosis. Sustained remission is achievable but uncommon, and most published outcome data come from small clinical samples rather than population cohorts.^1,3,5

Natural history

• Mean duration of untreated illness in clinical samples exceeds 15 years, reflecting both shame-driven concealment and clinician failure to ask about stealing.^1,3
• Course is typically chronic with fluctuating severity; episodic and intermittent patterns are described, often linked to mood symptoms or psychosocial stress.^1,5

Response and remission

• In the naltrexone RCT, two-thirds of patients on active treatment met response criteria at 8 weeks compared with about 8% on placebo, but longer-term remission rates are not well characterized.⁶
• Cognitive-behavioral case series report sustained reductions in stealing in a subset of patients, with relapse most common in the context of mood deterioration or psychosocial stressors.¹⁰

Suicide risk

• Lifetime suicide attempts are reported in roughly one-quarter of patients with kleptomania in clinical samples, an elevation that tracks more closely with comorbid mood disorder than with kleptomania itself.^1,3
• Suicidal ideation often follows arrest or public exposure rather than stealing episodes per se.³

Functional outcome

• Marital, occupational, and legal consequences are common; arrest is reported by more than half of patients in tertiary clinical samples.^1,3
• Patients who engage in treatment, particularly with combined pharmacotherapy and CBT, report better functional outcomes than those who do not, though selection bias limits this inference.^5,10

Kleptomania itself rarely produces a psychiatric emergency, but the comorbidities and consequences that bring patients to acute care do. The clinician's task is to triage these rather than to treat the stealing in the emergency department.^3,5

Suicide risk after arrest or public exposure:

• A new arrest, court date, or public exposure (employer, family) is a high-risk window for suicidal ideation and attempt in patients with comorbid mood disorder; safety assessment is mandatory.^1,3
• Standard suicide risk evaluation applies; there is no kleptomania-specific risk tool.³

Hospitalization criteria

• Standard psychiatric hospitalization criteria apply: imminent risk of self-harm, suicide, or inability to care for self.⁵
• Stealing behavior alone, in the absence of risk to self or others, does not justify involuntary admission.⁵

Agitation and acute distress

• Acute distress is most often driven by comorbid mood, anxiety, or substance use exacerbations and is managed accordingly.⁵

Forensic and confidentiality considerations

• Disclosure of ongoing or planned stealing in treatment does not generally trigger a duty to warn, in contrast to credible threats of violence; jurisdictions vary and clinicians should know local law.⁵

Kleptomania sits at the intersection of psychiatry, addiction medicine, and the criminal justice system, and disagreement persists about both its nosology and the validity of the diagnosis in forensic settings.^5,12

Nosologic placement

• Whether kleptomania is best classified as an impulse-control disorder, a behavioral addiction, or an obsessive-compulsive spectrum condition remains contested; DSM-5-TR retains it among Disruptive, Impulse-Control, and Conduct Disorders, while several authors argue the addiction framework better fits the urge-relief phenomenology and naltrexone response.^5,12
• ICD-11 places kleptomania in the Impulse Control Disorders grouping (6C71), reflecting the same uncertainty.¹⁴

Forensic validity

• The diagnosis is frequently invoked in shoplifting defenses, and some forensic psychiatrists argue it is over-diagnosed in defendants and under-diagnosed in clinical populations; structured assessment of the urge-tension-relief cycle and the non-acquisitive nature of stolen items is the partial remedy.⁵
• Malingering is a real consideration when the diagnosis is first raised in a forensic context, and corroborating history is essential.⁵

Evidence-base limitations

• Only one positive randomized controlled trial of any treatment exists, with 25 participants over 8 weeks, and long-term effectiveness data are absent.^6-7
• Cognitive-behavioral techniques are widely used but supported almost entirely by case series and small uncontrolled trials.¹⁰

Underdiagnosis and stigma

• Patients rarely volunteer the symptom, and clinicians rarely ask; the result is a long mean duration of untreated illness and entry into care through the legal system rather than primary care or psychiatry.^1,3,5

Neurobiology

• Imaging findings of reduced inferior frontal white-matter integrity and inferences about dysfunction in Ventral striatum reward circuitry are based on small samples and require replication before clinical translation.^8,12

• Kleptomania is defined by recurrent failure to resist urges to steal items not needed for personal use or monetary value, with a tension-relief cycle and stealing that is not motivated by anger, revenge, delusion, or hallucination.¹⁴
• DSM-5-TR classifies kleptomania within Disruptive, Impulse-Control, and Conduct Disorders; ICD-11 codes it as 6C71 within Impulse Control Disorders.¹⁴
• Lifetime prevalence is estimated at 0.3-0.6% in general population samples, with a roughly 2-3:1 female-to-male ratio in clinical samples.^2-4
• Mean age of onset is in adolescence, but mean age at first treatment contact is in the mid-thirties, reflecting a long duration of untreated illness.^1,3
• Psychiatric comorbidity is the rule: mood disorders (especially major depressive disorder), anxiety disorders, substance use disorders, eating disorders (particularly bulimia nervosa), and other impulse-control disorders.^1,9
• Stealing in kleptomania is non-acquisitive: items are typically discarded, returned, hoarded, or given away, distinguishing it from ordinary theft.^1,3
• Naltrexone, with one positive 8-week double-blind RCT (mean dose ~117 mg/day), is the only pharmacotherapy with controlled-trial support and is considered the agent of choice when medication is indicated.^6-7
• SSRIs have not demonstrated efficacy for kleptomania itself in controlled trials but are reasonable for comorbid depression or anxiety.⁷
• Covert sensitization and imaginal desensitization are the most studied CBT techniques and are considered first-line non-pharmacologic treatment.¹⁰
• New-onset stealing in an older adult should prompt evaluation for frontotemporal dementia and review for dopamine agonists associated with impulse-control symptoms.⁵
• Lifetime suicide attempt rates approach 25% in clinical samples and track most closely with comorbid mood disorder, not with stealing per se.^1,3
• The Kleptomania Symptom Assessment Scale (K-SAS) is the most commonly used severity instrument and is the primary outcome measure in the naltrexone RCT.⁶
• Pathological gambling and kleptomania share phenomenology and naltrexone response, supporting a behavioral-addiction framing of kleptomania.^5,12
• Court-mandated treatment is common; the clinician should clarify the limits of confidentiality and the distinction between treatment and forensic evaluation at the outset.⁵
