Persecution Mania: Symptoms, Causes, and Treatment Options

"Persecution mania" is a common term for persistent delusional ideas of persecution, that is, fixed false beliefs that "someone is watching, intentionally harming, or conspiring" that are inconsistent with reality and are resistant to persuasion. In modern psychiatry, this is not a distinct illness, but a category of delusion found in various disorders: from delusional disorder (persistent delusional disorder) to schizophrenia, as well as depression/mania with psychotic symptoms, intoxication, and somatic/neurological diseases. The key symptom is conviction in the absence of sufficient objective evidence and a persistent false explanation of events. [1]

It's important to distinguish between paranoid thoughts at the level of everyday alertness (which many people experience from time to time) and delusional beliefs. Research shows that 10-15% of people experience paranoid ideas from time to time, but this is not a delusion; delusional ideas are the "hard end" of this continuum and are usually accompanied by significant distress and impairment in functioning. [2]

Persecutory delusions most often occur within the schizophrenia spectrum or delusional disorder; they also occur in bipolar disorders, post-traumatic stress disorder (as "threatening beliefs"), stimulant intoxication, neurocognitive disorders, and hearing impairments. Treatment tactics depend on an accurate diagnosis: pharmacotherapy (antipsychotics), psychological methods (cognitive-behavioral therapy for psychosis, targeted protocols), family support, sleep and substance therapy. [3]

The term "persecution mania" historically refers to "paranoia," but in modern nomenclature, it is more accurate to refer to persecutory delusions as a symptom/syndrome rather than a disease. This helps to avoid stigma and select evidence-based interventions for a specific diagnosis. [4]

Code according to ICD-10 and ICD-11

There is no specific code for "persecution mania." The closest ICD-10 category is F22 "Persistent delusional disorders" (including subtypes with persecutory themes). Persecutory delusions also occur in schizophrenia (F20.x) and in mood disorders with psychotic symptoms—in these cases, the underlying disorder is coded. [5]

In ICD-11, persecutory delusions can be the leading symptom of 6A24 "Delusional Disorder" and also be included in 6A20 "Schizophrenia" or other primary psychotic disorders. ICD-11 provides detailed diagnostic requirements (minimum duration, exclusion of primary mood episodes, etc.), which helps to accurately define this nosology. [6]

Table 1. How conditions where persecutory delusions occur are coded

Clinical situation	Classifier	Code	Comment
Delusional disorder, persecutory theme	ICD-10	F22	Persistent delirium with relatively intact functioning. [7]
Delusional disorder	ICD-11	6A24 (± modifiers)	Duration ≥3 months, no prolonged mood episodes. [8]
Schizophrenia with persecutory delusions	ICD-11	6A20.*	Delusions + other spectrum symptoms, multiple domain disorders. [9]
Depression/mania with psychotic symptoms	ICD-11	6A7* / 6A6*	They code for mood disorder with psychotic features. [10]

Epidemiology

According to reviews, persecutory ideas, as a continuum of paranoid experiences, occur in 10-15% of the population (episodically, subclinically). However, persistent persecutory delusions are significantly rarer and fall within the clinical range. [11]

Delusional disorder is a rare entity: prevalence estimates range from approximately 0.02% to 0.1% (depending on the methods and population). During the first psychotic episode, persecutory delusions are very common: in some studies, ≥70% of patients have persecutory delusions at the onset of the illness. [12]

Schizophrenia generally occurs in approximately 0.7-1.0% of the population (lifetime prevalence estimates vary), and persecutory delusions are one of the most common types of delusional beliefs within this structure. In bipolar disorders, psychotic symptoms are significantly less common, but persecutory delusions are also possible during manic/major depressive episodes. [13]

The prevalence is increased by stress, sleep deprivation, stimulant use, and social factors (isolation, trauma). This reflects the association of persecutory delusions with anxiety, insomnia, and negative beliefs about the self/world. [14]

Reasons

There is no single "cause": persecutory delusions are the result of the interaction of biological, psychological, and social factors. Biological factors include inherited vulnerability, characteristics of dopaminergic transmission, and the functioning of prediction/salience networks. These factors increase the likelihood of erroneous "threat signaling" and the reinforcement of the erroneous belief. [19]

Psychological mechanisms include increased anxiety and "vigilance," a tendency to catastrophize the interpretation of ambiguous stimuli, sleep deprivation, and negative beliefs about one's own vulnerability. Experiments and clinical observations show that addressing anxiety, negative beliefs, and insomnia reduces the severity of persecutory delusions, indirectly confirming their causal role. [20]

Social determinants—isolation, stigma, traumatic experiences, discrimination—intensify the sense of threat and "merging" with the delusional idea. Psychosis-inducing substances (amphetamines, cocaine, high-potency cannabis) and some medications can provoke psychotic experiences, including persecutory delusions. [21]

In somatic medicine, persecutory delusions can arise from neurocognitive disorders, neuroinfections, vitamin B12 deficiency, endocrinopathies, and damage to the temporal lobes - these causes must be excluded in “late” onsets and in atypical clinical presentations. [22]

Risk factors

Individual factors include a family history of psychotic disorders, trait anxiety, insomnia, a tendency toward ruminative worry, and negative self-beliefs. These characteristics do not imply "doom," but they do increase the likelihood of fixation on the "threat." [23]

Substance use (stimulants, high-potency cannabis, synthetic cannabinoids), as well as alcohol and "mixed" intoxications, increase the risk of psychotic symptoms, especially in the context of sleep deprivation and stress. Sleep modification and substance abstinence are key preventative measures. [24]

Medical risk factors include late age of onset, acute onset of psychotic symptoms after starting/withdrawing medications, focal neurological symptoms - all of these are “red flags” of possible secondary (organic) psychosis and require extensive examination. [25]

The social context—isolation, high stress, mistrust, and traumatic experiences—increases alertness and "retrains" the threat-detection system. Psychotherapeutic and family interventions address this level. [26]

Table 3. Risk factors and points of application of prevention

Category	Examples	What helps?
Individual	Anxiety, insomnia, negative beliefs	CBT modules for anxiety/insomnia, psychoeducation. [27]
Substances	Amphetamines, cocaine, high-potency cannabis	Complete waiver/reduction, assistance programs. [28]
Medical	Late onset, neurological signals	Extended examination according to FEP protocols. [29]
Social	Isolation, trauma, stigma	Family/group support, EIP models. [30]

Pathogenesis

Contemporary models view persecutory delusions as a failure of salience attribution: neurotransmitter and network mechanisms (including dopamine signaling) enhance the sense of "hidden threat," while cognitive processes reinforce the misinterpretation through selective attention and confirmation biases. Experientially, this is experienced as "too much evidence that I'm being watched." [31]

Sleep and anxiety reinforce the cycle: insomnia increases negative affect and "abnormal internal states," anxiety focuses attention on the threat; together, they fuel delusional beliefs. Clinical studies have shown that treating insomnia and anxiety reduces the severity of persecutory delusions, supporting the causal model. [32]

At the "social level," past traumatic experiences and current isolation reduce basic trust and increase the likelihood of interpreting neutral events as hostile. Therefore, effective programs combine pharmacotherapy and psychological/social measures. [33]

In schizophrenia, several mental modalities (thinking, perception, motivation, cognition) are involved in the pathological process, so isolated impact on delusions without taking into account other domains rarely produces a lasting effect. [34]

Symptoms

The main characteristic is a persistent belief in persecution ("being watched," "will harm," "is orchestrated"), which is inconsistent with the facts and not shared by the cultural group. The person interprets neutral signs as evidence of a threat: "noise behind the wall is surveillance," "a passerby's glance is a signal." The belief persists despite refutations. [35]

Accompanying experiences: anxiety, hyperattention to "signs," insomnia, and sometimes anger or avoidance strategies (changing routes, closing windows, turning off phones). At their peak, conflicts with loved ones and neighbors, and calls to law enforcement, are possible. [36]

In schizophrenia, persecutory delusions may be combined with hallucinations, disorganized thinking, negative symptoms, and decreased social activity. In delusional disorder, functioning may be relatively intact outside the "delusional theme zone," but relationships and work still suffer. [37]

It's important to distinguish doubts/suspicion from delusions: with delusions, the conviction is firm, highly confident, and significantly influences behavior; criticism is minimal. This is precisely what makes help necessary. [38]

Classification, forms and stages

Clinically, the following are distinguished: 1) delusional disorder (persistent) with persecutory themes, 2) schizophrenia spectrum with persecutory delusions, 3) affective disorders (mania/depression) with psychotic features, 4) secondary (organic/induced) psychoses. Assignment to a group determines treatment. [39]

In terms of content, delusions can include stalking, poisoning, surveillance (including cyber-surveillance), conspiracy, eavesdropping, and sabotage at work/at home. Depending on the degree of "systematization," delusions can be a single belief or a complex "system" with "evidence." [40]

According to the course - acute onset (days/weeks) and persistent (months/years). Acute onset, late age, somatoneurological symptoms - a reason to look for secondary causes. [41]

Table 4. Working typology for practice

Option	Signs	Priorities
Persistent delusional disorder	Isolated persistent delirium, relative preservation	Antipsychotics, CBTp, social support
Schizophrenia spectrum	Delusion + other domains (hallucinations, negative)	Antipsychotics (including LAI), family interventions
Affective psychoses	Delirium + severe mood episodes	Mood episode therapy + antipsychotic
Secondary (organic/inducible)	Late onset/medications/intoxication	Diagnosis and treatment of the cause

Complications and consequences

Without treatment, persecutory delusions lead to social isolation, conflict, job loss, and relationship breakdown. Dangerous behaviors (self-defense, aggression "in response" to an imagined threat) and financial losses (locks/systems, "legal" actions) often develop. Perpetuating factors—insomnia and substance use—exacerbate the course. [42]

In schizophrenia, the risk of relapse is high without maintenance therapy; early intervention reduces the duration of untreated psychosis and improves long-term outcome. Long-term remission is possible with treatment adherence and comprehensive support. [43]

Some patients experience comorbid depression/anxiety, suicidal ideation - this requires active monitoring and treatment of concomitant conditions. [44]

Legal and family consequences (conflicts with neighbors, restraining orders, unnecessary spending) are often provoked by embarrassment and fear; psychoeducation of the family and its involvement in the safety plan reduce the risk of excesses. [45]

When to see a doctor

You should consult a psychiatrist/general practitioner if the suspiciousness has become persistent, is accompanied by a belief in a threat, changes behavior (avoidance, "defensiveness," conflicts), or disrupts work/study/sleep. This is not a "characteristic," but a condition that can be treated. [46]

Urgently - in case of risk to oneself or others (aggression, suicidal thoughts), in case of acute onset in middle and late age, in case of hallucinations with command content, in case of suspected intoxication or in case of abruptly changed behavior. [47]

Early referral to Early Intervention in Psychosis (EIP) services improves outcomes: the shorter the duration of untreated psychosis, the better the long-term outcomes. In some health systems, the target time for initiation of assessment is up to two weeks from referral. [48]

If you have insomnia, anxiety, or substance use, begin addressing them at the same time - this will reduce the severity of delusional beliefs and increase the effectiveness of treatment. [49]

Diagnostics

Step 1. Clinical interview. The psychiatrist assesses the content of beliefs, degree of certainty, evidence for/against, impact on behavior, and criticality. Triggers, sleep, substances, family and medical history, and traumatic experiences are identified. A basic risk assessment is also conducted. [50]

Step 2. Screening for organic causes. For the first episode of psychosis (especially late onset/atypicality), a "reasonably broad" laboratory panel is recommended: complete blood count, electrolytes, glucose, thyroid function, vitamin B12/folate, liver/renal parameters, toxicology screening; if indicated - syphilis/HIV, autoimmune markers. Neuroimaging (CT/MRI) - for red flags (focal neurology, trauma, seizures, late onset). EEG - if epilepsy is suspected. [51]

Step 3. Differential assessment. The nosology is determined: delusional disorder, schizophrenia/other primary psychoses, mood disorders with psychotic symptoms, induced substances/medications, secondary psychoses (endocrine, neurological, deficiency, infectious). In adolescents and young adults - referral to early intervention programs. [52]

Step 4. Treatment and monitoring plan. Goals are jointly formulated (reducing beliefs and anxiety, improving sleep and functioning), pharmacotherapy/psychotherapy is selected, and family involvement is included. Standards for monitoring antipsychotic side effects are followed, and maintenance therapy and visits are planned. [53]

[54]

Differential diagnosis

Delusional disorder vs. schizophrenia. Delusional disorder is characterized by isolated, persistent delusions with relatively intact functioning outside of the "theme"; schizophrenia is characterized by multiple domains of disturbance (thinking, perception, motivation, affect), most often hallucinations and negative symptoms. [55]

Affective disorders with psychotic features. In mania/severe depression, psychotic ideas are consistent with mood (hostile world, guilt/sin in depression; grandiosity/persecution in mania). Diagnosis is based on the dominant affective episode. [56]

Secondary (organic/induced) psychoses. Characterized by late onset, acute onset, association with substance/medication use/withdrawal, and somatoneurological signs. Here, the primary focus is on identifying and treating the underlying cause (endocrine, deficiency, infectious, or neurological). [57]

Obsessions and PTSD. Obsessions are perceived as "foreign" and ego-dystonic, and the person remains critical; in PTSD, a real past threat and hypervigilance are experienced, but without a fixed delusional belief. Correct differentiation changes treatment. [58]

Table 6. What to confuse with what and how to distinguish

State	Key Features	Diagnostic emphasis
Delusional disorder	Isolated persistent delirium	Exclude affective episodes/organic
Schizophrenia	Nonsense + ≥1 other domains	Full psychotic spectrum, duration
Affective psychosis	Delirium is consistent with the mood	Mood episode treatment + antipsychotic
Secondary psychosis	Late onset/intoxication/neurology	Lab. + instrumental search for cause

Treatment

Psychoeducation and alliance are the first step. We explain that persecutory delusions are a treatable symptom, and the goal is to reduce the belief/distress and restore functioning. We discuss the impact of sleep, anxiety, and substances; agree on a "safety plan" and involve the family (at the patient's request). We clearly document early signs of relapse and develop an action plan. [59]

Pharmacotherapy is the mainstay of treatment for schizophrenia spectrum disorders and moderate to severe delusional disorder. Second-generation antipsychotics (e.g., risperidone, olanzapine, aripiprazole, etc.) reduce the severity of delusions and the risk of relapse. The choice of medication is based on the side effect profile and preferences. For relapse prevention in patients with poor adherence, long-acting injectable formulations (LAI) are considered; they have been shown to reduce the risk of rehospitalization and relapse compared to oral administration in some patients. [60]

In cases of treatment-resistant schizophrenia (insufficient response to adequate trials of two antipsychotics), clozapine remains the gold standard. It is superior to other medications in its effectiveness in treating treatment-resistant schizophrenia and reduces the risk of relapse. Monitoring of blood levels and side effects is required. Delayed administration of clozapine worsens the prognosis; it is important not to delay treatment if resistance criteria are met. [61]

Cognitive behavioral therapy for psychosis (CBTp) is recommended by international guidelines (e.g., NICE) as an adjunct to medication: it reduces delusional beliefs and distress (small to medium effect, increasing over time), and helps develop alternative explanations and coping skills. Structured goals and transference to everyday situations are important. [62]

Targeted protocols for persecutory delusions. The most promising program is Feeling Safe (Oxford): a theoretically based cognitive therapy that addresses perpetuating factors (anxiety, insomnia, negative beliefs, social fears, vulnerability). In a 2021 randomized trial, Feeling Safe demonstrated a significant reduction in persecutory delusion beliefs and superior effects compared to "friendly communication"; subsequent studies and reviews support its clinical utility. Research into online adaptations is ongoing. [63]

Working with sleep and anxiety is essential. Insomnia and anxiety intensify persecutory thoughts; the use of CBT-I and anxiety modules improves outcomes and reduces the severity of delusions. This is especially important for those with frequent nighttime "checking," reading disturbing content before bed, and shift work. [64]

Family interventions and psychoeducation increase adherence, reduce family stress, and reduce the risk of relapse; they are recommended for both initial episodes and chronic illness. Involving loved ones helps recognize early signs of exacerbation and address triggering situations (conflicts, overload, and disruptions to routine). [65]

Early Intervention in Psychosis (EIP) - multidisciplinary teams working with young people in the early years of illness: medication, psychotherapy, educational/work support, family support. Reducing the duration of untreated psychosis is associated with better functioning outcomes and a lower risk of relapse; the target time for initiation of assessment is within 2 weeks. [66]

Comorbidities and substances. Depression/anxiety is treated simultaneously, and substance use is addressed (motivational interviewing, abstinence programs, and, if necessary, specialized support). The use of stimulants and high-potency cannabis increases persecutory delusions and impairs treatment response – this should be discussed directly and supportively. [67]

Maintenance management. After the acute phase has subsided: transition to the minimum effective maintenance dose, discussion of LAI in case of difficulties with taking it, regular monitoring of metabolic parameters and side effects, skills for self-monitoring of triggers (stress/sleep/conflicts), action plan for early signs of relapse (increased conviction, increased checking/avoidance). [68]

Prevention

Early intervention when persistent suspicions arise and behavior changes is the best prevention of severe consequences: early intervention reduces the duration of untreated psychosis and improves outcome. [73]

Sleep hygiene and stress management reduce vulnerability to "threatening" thinking. Maintain regular sleep, limit nighttime news/anxiety-inducing content, and practice relaxation techniques. [74]

Withdrawal from psychoactive substances (especially stimulants and high-potency cannabis) is critical, as they trigger and maintain delusional thoughts. Discuss reduction/withdrawal plans with a professional. [75]

Social support and reduced isolation (family, groups, mentoring, educational/work programs) reduce anxiety and improve outcomes. Early connection to employment and education services reduces functional losses. [76]

Forecast

The prognosis depends on the underlying disorder, the speed of treatment initiation, and adherence. In delusional disorder, some patients achieve a sustained reduction in beliefs and good social functioning. In schizophrenia, supportive therapy and psychosocial interventions significantly reduce the risk of relapse and improve quality of life. [77]

The use of LAI medications reduces the likelihood of rehospitalization and improves the stability of remission in patients with adherence difficulties. In patients with resistance, timely administration of clozapine increases the chances of clinical improvement and functional recovery. [78]

Targeted cognitive protocols (e.g., Feeling Safe) improve outcomes for beliefs and distress in some patients, particularly when combined with background pharmacotherapy and sleep/anxiety management. [79]

The most important moderators are substance abstinence, insomnia treatment, a supportive family/social environment, and an early response plan for relapse. When these are in place, long-term trajectories become significantly more favorable. [80]

FAQ

Is this a separate disease or a symptom?
This is a symptom/theme of delusion, occurring in various diseases (delusional disorder, schizophrenia, affective psychoses, secondary psychoses). The underlying nosology is coded (e.g., ICD-10 F22; ICD-11 6A24/6A20). [81]

Is it possible to treat without medication?
In mild, isolated cases that maintain functioning, psychotherapeutic protocols (CBTp, Feeling Safe) and sleep/anxiety/stress management are helpful. However, in the schizophrenia spectrum, antipsychotics are the baseline, with psychotherapy added on top. [82]

What new methods are available?
The Feeling Safe program demonstrated the best results to date in reducing persecutory delusion beliefs in RCTs (2021) and is being developed in online formats; the use of LAI antipsychotics for relapse prevention is expanding. For treatment-resistant patients, clozapine is used. [83]

Should an MRI/CT scan be performed?
Not everyone should. Neuroimaging and EEG are indicated in cases of late onset, neurological symptoms, trauma, seizures, and atypical presentation to rule out secondary causes. Basic testing and toxicology are recommended for the first episode. [84]

Does sleep really influence delusions?
Yes. Insomnia increases negative affect and alertness; treating insomnia reduces the severity of persecutory delusions. This is one of the most underappreciated tools for treatment. [85]
