Psychosis: Symptoms, Causes, Types, and When to Seek Help
Author: Ukrainian Psychological Hub · Published: October 9, 2026 · Editorial Policy
Psychosis is a clinical syndrome involving a significant disruption in how a person perceives or interprets reality. It can include hallucinations, delusions, and disorganized thinking or behavior. Psychosis describes a pattern of symptoms rather than one particular diagnosis: it may develop in schizophrenia-spectrum disorders, mood disorders, after exposure to some substances or medications, or during medical or neurological illness. Some psychotic experiences are brief; others need continuing care. The National Institute of Mental Health (NIMH) describes psychosis as a collection of symptoms that can interfere with recognizing what is real.
The practical questions are what the experience means, what else might explain it, whether there is immediate medical danger, and how to obtain the right assessment. A new episode of possible psychosis deserves timely professional evaluation, especially when sleep, self-care, relationships, work, school, or safety are affected. Early intervention can improve outcomes, while the underlying cause determines the appropriate treatment.
What Is Psychosis?
Psychosis is a term clinicians use when experiences such as perceiving something without an external source, holding a strongly fixed belief that is at odds with available evidence, or having markedly disorganized speech indicate a disturbance in reality testing. Reality testing is the capacity to evaluate internal experiences and interpretations against information from the world. The term describes a clinical phenomenon, and the nature, intensity, duration, context, and consequences of symptoms all matter.
A person may know that a voice is part of an unusual experience yet still feel frightened by it; someone else may be completely convinced that a television broadcast contains a message specifically directed to them. Neither example alone establishes the cause. Clinicians evaluate the wider clinical picture, including mood, cognition, medical history, medication exposure, and changes over time. NIMH's clinical overview emphasizes that psychosis can occur in different mental and physical health conditions.
Psychosis is not interchangeable with schizophrenia. Schizophrenia is a defined psychiatric disorder diagnosed using a pattern of symptoms, duration, functional effects, and exclusion of alternative explanations. Psychosis can also accompany bipolar episodes, severe depressive episodes, intoxication, withdrawal, delirium, neurocognitive illness, and other conditions. Some people experience a psychotic episode without ever receiving a schizophrenia diagnosis.
Signs and Symptoms of Psychosis
The most recognizable psychotic symptoms are hallucinations and delusions. Disorganized thinking and behavior can also be prominent. Associated sleep disturbance, anxiety, social withdrawal, changes in self-care, and reduced functioning may develop before, during, or after an episode. These associated changes are clinically important, but they are not by themselves proof of psychosis. The NIMH guide distinguishes psychotic symptoms from warning signs that can occur in many circumstances.
Hallucinations
A hallucination is a perception-like experience that occurs without a corresponding external stimulus. A person might hear a voice commenting on their actions, see something that other people cannot see, or experience unusual tactile or olfactory sensations. Auditory hallucinations are especially familiar in psychotic disorders, but hallucinations can also arise during sleep transitions, significant sensory impairment, certain medical illnesses, substance effects, and other circumstances.
The clinical assessment asks whether the experience is fully waking, where the person experiences the voice or image as coming from, how often it occurs, whether it feels controllable, and whether it is accompanied by delusions, confusion, depression, mania, or neurological symptoms. Hearing a voice does not automatically mean schizophrenia, and the distress and impairment associated with the experience may matter as much as the perceptual phenomenon itself.
Delusions
A delusion is a strongly held belief maintained despite substantial contrary evidence and understood in its cultural and personal context. A person may believe that strangers are monitoring them, that ordinary events carry messages intended only for them, or that an outside force controls their thoughts or actions. Clinicians assess conviction, preoccupation, flexibility, consequences, and the broader symptom pattern rather than labeling any unpopular or mistaken belief a delusion.
Suspiciousness is not equivalent to a persecutory delusion. Real experiences of discrimination, threat, abuse, and surveillance require careful consideration. Cultural and religious beliefs also cannot be classified as delusions merely because they are unfamiliar to an assessor. In a related but separately owned English Hub article, OCD and Paranoia: Intrusive Doubt, Poor Insight, Delusions, and Differential Diagnosis examines why the structure of a thought matters more than its subject.
Disorganized thinking, speech, and behavior
Disorganized thinking may become visible in speech that repeatedly loses its logical thread, shifts abruptly between unrelated topics, or is difficult for another person to follow. Marked behavioral disorganization may affect ordinary activities, judgment, or personal care. Some presentations involve severe motor changes, including catatonic signs such as immobility, unusual posturing, mutism, or extreme agitation.
A tired, anxious, distracted, or neurodivergent person may speak in an unconventional way for reasons unrelated to psychosis. Clinicians look at the severity of the change, the person's usual communication style, accompanying symptoms, the timeline, and possible medical explanations.
Negative symptoms and cognitive difficulties
In schizophrenia-spectrum conditions, negative symptoms describe reductions in ordinary motivation, expressive behavior, speech, social interest, or capacity to initiate activities. Cognitive difficulties may involve attention, memory, processing speed, or planning. These features can be important in long-term functioning but are not specific proof of psychosis. Depression, medication effects, sleep loss, environmental deprivation, and physical illness can also contribute to similar presentations. NIMH's schizophrenia overview separates psychotic, negative, and cognitive symptom dimensions.
Early Warning Signs and Changes Before an Episode
Some people experience a gradual period of change: deteriorating sleep, mounting suspiciousness, less effective communication, withdrawal from friends, declining academic or occupational performance, or unusual perceptual experiences. Others develop symptoms suddenly. There is no universal sequence, and many early warning signs are nonspecific. Anxiety, trauma-related distress, depression, sleep disorders, substance exposure, and major life disruption may also account for them.
What makes a change clinically important is its persistence, escalation, associated distress, or impact on functioning, particularly when the person is struggling to judge whether experiences are externally real. A first appointment can be useful before a definitive diagnosis is possible. Current NICE guidance on possible psychosis recommends assessment without delay for people with attenuated or intermittent psychotic experiences accompanied by distress or reduced social functioning.
A clinical high-risk state for psychosis is a specialist research and assessment construct that includes particular combinations of attenuated symptoms, brief limited psychotic experiences, or other defined risk criteria. It is not a confirmed psychotic disorder and is not a prediction of what must happen next. A meta-analysis of 130 studies estimated that about one quarter of selected individuals meeting clinical high-risk criteria transitioned to psychosis within three years. That estimate applies to assessed high-risk samples, not people in the general population who occasionally have unusual thoughts.
What Causes Psychosis?
Psychosis has several possible pathways. In primary psychotic disorders, vulnerability involves complex interactions among inherited factors, brain development, and environmental exposures. In other cases, psychotic symptoms arise in the context of a severe mood episode, drug exposure, medication effects, sleep deprivation, or a medical condition. Identifying the mechanism in an individual requires professional evaluation rather than inference from a symptom list. NIMH describes this multifactorial picture.
Psychiatric conditions
Schizophrenia, schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, and delusional disorder can involve psychotic symptoms, but their diagnostic patterns differ. Bipolar disorder can involve psychotic features during a manic or depressive episode; major depressive disorder can involve psychotic features during a severe depressive episode. The timing of psychotic symptoms in relation to mood episodes is one of the most important differential-diagnostic questions.
A history of trauma or high stress may be clinically relevant, but neither exposure alone diagnoses psychosis nor does a stressful event provide a sufficient explanation for every hallucination or delusion. Clinicians assess the full situation rather than assigning one cause from a single association.
Substances, prescribed medicines, and withdrawal
Cannabis, stimulants, hallucinogens, and other substances can be associated with psychotic symptoms, and symptoms may also emerge during intoxication or withdrawal from certain substances. Some prescribed medicines can contribute to psychotic symptoms in susceptible people. A medication or substance history includes what was taken, how much, when it was taken, recent changes, whether sleep was lost, and what symptoms remained after the exposure ended.
Temporality matters but does not settle diagnosis by itself. A substance-associated episode may resolve, persist, recur, or reveal an underlying vulnerability. It is unsafe to conclude that every episode after cannabis use is identical, or that symptoms continuing after exposure necessarily establish schizophrenia. The NIMH overview explicitly identifies substances and prescription medicines among possible causes.
Medical and neurological causes
Clinicians consider causes such as delirium, seizures, autoimmune or infectious illnesses, metabolic or endocrine disturbances, medication toxicity, and other neurological conditions when the presentation suggests them. The appropriate examination and tests are guided by age, timing, vital signs, neurological findings, cognition, substance exposure, and other symptoms. New-onset psychosis with rapidly fluctuating attention, fever, severe headache, seizures, recent head injury, or other physical changes calls for immediate medical consideration.
Psychosis appearing for the first time late in life requires special attention to neurological, cognitive, and medical explanations. NIMH notes that Parkinson's disease, Alzheimer's disease, and related conditions may be associated with psychotic symptoms. The objective is to recognize treatable causes without subjecting every patient to the same indiscriminate set of investigations.
Sleep and stress
Severe sleep deprivation can contribute to perceptual disturbances and altered interpretations of reality. Sleep loss can also accompany developing mania, anxiety, substance exposure, or another health condition. A clinician considers whether disrupted sleep is a contributor, an early marker, or a consequence of a broader syndrome. Restoring sleep is often useful, but it does not replace assessment when hallucinations, delusions, disorganization, or impaired judgment are present.
Types of Psychosis and Related Diagnoses
The word types may refer either to different symptom presentations or to the disorders and circumstances in which psychosis occurs. These categories help guide clinical reasoning, but they are not self-diagnostic labels. Modern diagnostic practice does not use the historical paranoid, disorganized, and catatonic subtypes of schizophrenia as current DSM-5-TR diagnoses.
Schizophrenia and the schizophrenia spectrum
Schizophrenia involves a characteristic constellation of symptoms and a longitudinal course assessed according to formal diagnostic criteria. Schizophreniform disorder describes a similar symptom pattern with a shorter defined duration. Brief psychotic disorder involves a short-lived episode meeting its own duration and exclusion criteria. Schizoaffective disorder requires a distinctive relationship between psychotic symptoms and major mood episodes over the course of illness. Delusional disorder is centered on delusions with a different overall pattern of functional and other psychotic features.
Duration and mood history are meaningful, but the full diagnostic criteria also include severity, functioning, context, and exclusions. Terms used in DSM-5-TR and ICD-11 are related yet not always identical in their definitions. See the WHO description of schizophrenia for an official overview of the disorder and its functional effects.
Mood disorders with psychotic features
Psychosis may occur during mania or severe depression, and these presentations need mood-focused differential diagnosis and care. In bipolar disorder, the relationship to manic or depressive episodes can be central. Psychotic depression requires assessment of the depressive syndrome and psychotic features together. Their comprehensive treatment pathways belong to the English Hub's separate mood-disorder coverage, because sharing psychotic symptoms does not make the disorders clinically interchangeable.
Substance-induced and medication-induced psychosis
A substance- or medication-induced presentation is considered when exposure and symptom onset have an appropriate temporal and clinical relationship and competing explanations have been assessed. A professional may need to follow the person over time before determining whether symptoms were transient, exposure-related, or part of a more persistent psychiatric condition.
Psychosis due to another medical condition
This diagnosis requires clinical evidence that a medical or neurological condition is causing the psychotic disturbance. Delirium deserves special separation: it is an acute disturbance of attention and awareness with a fluctuating course, often from a serious medical problem, and it can include hallucinations or delusions. Urgent treatment of the underlying medical cause can be critical.
Unspecified presentations and first-episode psychosis
An initial assessment may document psychosis or an unspecified psychotic disorder while further information is gathered. First-episode psychosis describes the clinical situation of a person's first recognized episode, regardless of whether the eventual diagnosis is schizophrenia, a mood disorder, a substance-related condition, or another explanation. It is a starting point for coordinated assessment and care, not a permanent diagnosis.
What Psychosis Can Feel Like
Descriptions from people experiencing psychosis vary substantially. A voice may feel intrusive, familiar, accusatory, or comforting; a belief may seem unquestionably true; ordinary sounds, faces, signs, or coincidences may acquire a personally significant meaning. Other people may feel intensely frightened, overwhelmed, or confused, while some report little distress. An observer often sees changes in communication or behavior before understanding what the person is experiencing.
The person may resist the idea that something is wrong because the experience itself seems real. The most productive clinical and personal response involves listening, checking safety, and focusing on distress and practical needs without escalating a dispute about the content of the belief. A person with psychosis is still a participant in decisions about their life and treatment.
How Doctors and Mental Health Professionals Diagnose Psychosis
Assessment begins with a careful history of the specific experiences, their onset and timeline, associated mood symptoms, sleep, functioning, medical illness, medications, and substance exposure. Clinicians also evaluate attention, memory, consciousness, movement, suicidal thoughts, immediate physical symptoms, and safety needs. With consent and appropriate confidentiality safeguards, information from family members or trusted people may clarify changes that are difficult to reconstruct during an acute episode.
A mental status examination explores perception, thought content, thought organization, speech, behavior, affect, cognition, and insight. The clinician considers the person's language, cultural setting, developmental history, disability accommodations, and usual functioning. Medical examination and investigations are selected according to findings; tests may help identify an underlying cause, but there is no single laboratory result, brain scan, questionnaire, or online score that can independently confirm schizophrenia or explain every psychotic experience.
The 2023 VA/DoD clinical practice guideline includes pathways for suspected psychosis, first-episode care, and antipsychotic treatment. The NICE adult guideline similarly calls for comprehensive multidisciplinary assessment of psychiatric, medical, psychological, and social factors. When diagnosis remains uncertain, follow-up can be part of good care rather than a failure of assessment.
What clinicians distinguish during assessment
A hallucination is one possible psychotic symptom; a delusion is a belief phenomenon; disorganization affects thinking or behavior. Psychosis is the broader clinical presentation. Schizophrenia is one possible disorder behind that presentation. A risk factor changes probabilities in a population but does not diagnose a person. A screening result signals that fuller assessment may be worthwhile. A clinical high-risk designation has specialist criteria and uncertainty. A confirmed diagnosis requires a qualified professional's assessment using an appropriate diagnostic framework.
A person can have obsessive intrusive thoughts, trauma-related dissociation, sensory disturbances, intense worry, or culturally meaningful experiences that superficially resemble psychotic symptoms. These distinctions are resolved by context and history rather than by asking whether someone has ever heard a sound, felt watched, or feared losing control. For a closely related existing topic, the Hub's OCD and Paranoia article examines obsessional doubt versus delusional conviction.
First-Episode Psychosis and Why Early Care Matters
Early treatment can reduce the period during which psychosis is untreated and help people resume education, relationships, work, and everyday activities. It also creates an opportunity to identify medical causes, address mood or substance-related factors, and establish a trusted therapeutic relationship before repeated crises. Early treatment does not guarantee a particular outcome, and its benefits depend on access to appropriate services and the individual's circumstances.
Coordinated specialty care brings together medication management when indicated, evidence-based psychotherapy, family support and education, case management, and support for school or work. In the NIMH RAISE research program, a randomized comparison of comprehensive coordinated care and usual community care found benefits in several clinical and functional outcomes over two years. The trial is reported by Kane and colleagues in the American Journal of Psychiatry; NIMH's clinical guide explains the coordinated specialty care model.
A referral to a first-episode psychosis or early-intervention team is useful when available. The team can assess and treat the episode even if a final disorder label is not yet clear. For children and adolescents, developmental context, safeguarding, education, and family participation need careful attention. NICE's guidance for under-18s recommends prompt specialist assessment when possible psychosis is identified.
Treatment of Psychosis
Treatment depends on the cause, severity, person's preferences, and immediate safety needs. For psychosis associated with an infection, delirium, medication reaction, intoxication, or withdrawal, medical management of the underlying condition may be central. For primary psychotic disorders, care frequently combines antipsychotic medication, psychological and family interventions, and practical support for recovery. A treatment plan should be reviewed as clinical understanding evolves.
Antipsychotic medication and safety monitoring
Antipsychotic medicines can reduce hallucinations, delusions, agitation, and other symptoms in appropriately diagnosed psychotic disorders. Individual response and adverse effects vary. Possible concerns include weight gain, changes in blood sugar and lipids, movement-related adverse effects, sedation, hormone-related effects, and cardiovascular risks. The decision to start, continue, change, or withdraw a medicine requires a clinician's assessment and discussion of expected benefits, alternatives, monitoring, and the person's priorities.
NICE recommends baseline assessment of weight, blood pressure, metabolic indicators, movement disorders, and relevant cardiovascular risk, with ongoing monitoring. For schizophrenia that has not responded adequately to appropriate trials of at least two antipsychotic medicines, clozapine may be indicated under specialist supervision with required safety monitoring. Medication changes should be planned with the prescriber; abrupt self-directed discontinuation can create avoidable risks.
Cognitive behavioral therapy for psychosis
Cognitive behavioral therapy for psychosis (CBTp) is a structured psychological intervention that can help people examine interpretations, develop ways to respond to distressing voices or beliefs, reduce distress, and improve functioning. Therapy need not begin by demanding that a person abandon every strongly held experience. The approach works with the person's goals, coping strategies, and functioning. Its effects vary and it is generally integrated with other indicated care rather than treated as a universal replacement for medication.
The NICE guideline recommends CBT and family intervention for people with psychosis or schizophrenia, alongside pharmacological options when indicated. It also distinguishes evidence for combined treatment from the more limited evidence for psychological treatment alone in some presentations.
Family psychoeducation, social care, and recovery support
Family psychoeducation helps relatives and supporters understand symptoms, respond constructively, manage stress, and navigate treatment or crisis plans. Supported employment and education services, coordinated case management, accommodations, housing stability, attention to physical health, and opportunities for meaningful relationships can be essential elements of care. Cognitive remediation may be considered for appropriate cognitive goals in schizophrenia-spectrum care, although its role should be personalized rather than presented as a cure for psychosis.
A person-centered recovery plan includes what matters to the individual: feeling safe, being heard, improving sleep, returning to school or work, maintaining family relationships, pursuing interests, and managing symptoms when present. Recovery is broader than symptom reduction. The WHO schizophrenia fact sheet describes meaningful possibilities for recovery while acknowledging treatment gaps and discrimination.
When to Seek Help for Possible Psychosis
Seek a timely medical or mental health assessment when a person develops new hallucinations, strongly fixed unusual beliefs, markedly disorganized speech or behavior, or increasing difficulty distinguishing perceptions from shared reality. A prompt appointment is particularly important when the experiences are escalating, distressing, or interfering with basic self-care, sleep, school, work, or relationships. A primary care clinician can help begin an evaluation, but suspected first-episode psychosis often merits rapid specialist involvement.
Seek emergency medical help immediately when psychotic symptoms occur with sudden confusion or fluctuating consciousness, high fever, seizures, severe headache, recent head injury, signs of poisoning or withdrawal, or other serious physical symptoms. The same applies when a person cannot meet basic needs, is severely agitated or immobile, or appears at immediate risk of harming themselves or another person. Catatonia, especially with inability to drink, immobility, autonomic instability, or fever, warrants urgent medical assessment. These presentations can involve serious medical conditions.
If there is imminent danger, contact local emergency services. In the United States, 911 is the emergency number, and a person experiencing suicidal thoughts or an emotional crisis can call or text 988 for the Suicide & Crisis Lifeline. These resources are location-specific; outside the United States, use your own country's emergency and crisis services. The NIMH psychosis resource includes U.S. help-seeking guidance.
The practical rule is to respond to safety, suddenness, and functional change rather than waiting to determine a diagnosis at home. An assessment can identify medical urgency, provide support, and arrange follow-up even when the final explanation remains uncertain.
How to Help Someone Who May Be Experiencing Psychosis
Start by creating a calm and physically safe setting. Speak clearly and respectfully, offer to listen, and describe the changes you have noticed without ridicule or confrontation. You can acknowledge that an experience is frightening or exhausting without endorsing an unverified interpretation. For example, it is reasonable to say that you understand how distressing it feels and want to help find someone who can assess what is happening.
Ask about immediate practical needs: whether the person has slept, eaten, hydrated, taken prescribed medication as directed, and has somewhere safe to stay. Encourage professional assessment and, when welcomed, offer to help arrange an appointment or accompany the person. Avoid making promises of secrecy if there is an immediate risk of serious harm. Respect privacy, autonomy, and cultural context while following local emergency procedures when safety is threatened.
If the person refuses help, consider discussing your observations with a qualified clinician or local early-intervention service for guidance on appropriate next steps. Family members and friends can provide support while allowing professional care to determine diagnosis and treatment. Repeated arguments over whether voices or beliefs are real tend to divert attention from the person's distress and immediate needs.
Psychosis in Adolescents, Older Adults, and Other Groups
Adolescent experiences must be interpreted in relation to development, sleep, stress, substance exposure, and other psychiatric or medical concerns. A sustained change in functioning or concerning psychotic symptoms merits specialist evaluation. NICE's child and adolescent guideline addresses assessment, family involvement, psychological interventions, education, and medication decisions made with appropriately trained specialists.
In later adulthood, new psychotic symptoms may have different probable causes and require a careful review of physical illness, medication effects, sensory impairment, cognitive change, and neurological disease. Medical evaluation is especially important when symptoms develop abruptly or fluctuate with attention or consciousness.
After childbirth, the abrupt onset of severe mood and psychotic symptoms can indicate postpartum psychosis, a psychiatric emergency. This condition belongs to a distinct perinatal care pathway and requires urgent specialist and medical assessment. Its presence in the differential does not make postpartum psychosis a subtype of schizophrenia.
Can Psychosis Go Away? Recovery and Prognosis
Outcomes vary by cause, age, duration of untreated symptoms, access to appropriate treatment, co-occurring conditions, social support, and other personal circumstances. Some people recover from a brief episode and never experience another; others have recurring symptoms or require long-term care. In any trajectory, recovery-oriented services can support physical health, education, employment, autonomy, relationships, and quality of life.
A high-risk assessment also does not dictate an inevitable course. A systematic review and meta-analysis of individuals at clinical high risk who did not transition found that many experienced improvements in symptoms and functioning, although some continued to need care. This reinforces the need for follow-up based on current needs rather than treating a risk label as a future diagnosis.
Stigma can disrupt care, housing, employment, social participation, and relationships. Psychosis should be discussed as a health presentation with diverse causes and outcomes. Most people living with psychotic disorders are not violent; clinical attention to possible violence should be based on individual risk and immediate circumstances, not diagnosis-based stereotypes. The WHO fact sheet explicitly addresses the human rights and discrimination experienced by people with schizophrenia.
Frequently Asked Questions
Is psychosis the same as schizophrenia?
Psychosis is a clinical symptom cluster that can occur in multiple disorders or medical situations. Schizophrenia is one defined psychiatric disorder in which psychotic symptoms may occur alongside other symptom dimensions and characteristic longitudinal features. A psychotic episode by itself does not establish schizophrenia.
Can anxiety or sleep deprivation cause symptoms that resemble psychosis?
Intense anxiety and lack of sleep can alter perception, concentration, and interpretation. Severe sleep deprivation may contribute to hallucination-like experiences. Anxiety, panic, intrusive thoughts, and derealization can be mistaken for psychosis, and psychosis may also coexist with anxiety. Persistent or escalating changes need individualized evaluation.
Are hearing voices and hallucinations always signs of a psychotic disorder?
No. Some people report auditory experiences during sleep transitions, sensory changes, grief, or other nonpsychotic circumstances. Clinicians assess consciousness, conviction, distress, other symptoms, medical factors, and functional effects rather than assigning a diagnosis from the experience alone.
What is the difference between psychosis and delirium?
Psychosis describes a disturbance in perception, belief, or thinking. Delirium is an acute disturbance of attention and awareness, usually with fluctuating symptoms and often a medical cause. Delirium may include hallucinations or delusions; suspected delirium requires urgent medical evaluation.
Is psychosis permanent?
An episode may resolve completely, recur, or become part of a longer course depending on its cause and the care received. No single trajectory applies to everyone. Timely assessment helps identify treatable contributors and appropriate recovery support.
Can someone have insight during psychosis?
Yes. Insight varies and can change over time. A person may recognize that some perceptions are unusual while continuing to experience them as compelling or distressing. Partial insight neither rules out psychosis nor determines the underlying diagnosis.
Does psychosis mean someone is dangerous?
Psychotic symptoms do not by themselves establish dangerousness. Most people with psychotic disorders are not violent. Safety assessments concern specific behavior, circumstances, acute distress, suicidal thoughts, medical instability, and other individualized factors.
Should antipsychotic medication be started for everyone who seems at risk?
No. People meeting clinical high-risk criteria need specialized assessment and care matched to their symptoms and needs. NICE guidance advises against prescribing antipsychotics solely to prevent psychosis in high-risk states. Confirmed psychosis requires a separate, individualized treatment decision.
What should I do if I think this is my first episode of psychosis?
Arrange a prompt clinical assessment, ideally through a service experienced in first-episode psychosis. If there is sudden confusion, fever, neurological symptoms, severe inability to care for yourself, or imminent danger, seek emergency medical help. Share the timeline of symptoms and any medication or substance exposure with the assessing clinician.
