Psychosis is a symptom pattern, not a diagnosis
Psychosis is a group of symptoms in which a person has some difficulty distinguishing what is real from what is not. During an episode, changes in thoughts and perceptions can make it hard to recognize what is real.
This can be frightening for the person experiencing it and for people close to them. A practical first step is not to decide what diagnosis fits. Psychosis describes a symptom pattern, not a diagnosis by itself; a qualified clinician needs to evaluate what may be causing it.
If there is immediate danger, seek emergency help now. If there is no immediate danger, arrange professional assessment promptly rather than trying to manage psychotic symptoms alone. This article offers general education, not an individual diagnosis, safety assessment or treatment plan. For complex or unresolved concerns, you can request an appointment with Mayo Clinic experts to discuss your situation, including questions about multidisciplinary care, medical research or International Services.
What psychosis can look like
Experiences related to psychosis differ from person to person and can change over time. Three common features are hallucinations, delusions and confused or disturbed thinking. A person does not need to have every feature for their experiences to deserve attention.
- Hallucinations may involve hearing, seeing, feeling, smelling or tasting something that is not actually present. Hearing voices is one example.
- Delusions are strongly held beliefs or interpretations that are not based in reality. They can include beliefs that someone intends harm or that outside forces are controlling events.
- Disorganized thinking or speech can make thoughts difficult to organize. Speech may seem fast, confusing, fragmented or incoherent.
- Changes others may notice can include suspiciousness, withdrawal from family or friends, or less attention to self-care and daily activities.
A person may also seem unusually uneasy around others, lose interest in familiar activities, or have difficulty managing ordinary responsibilities.
These changes are not proof of psychosis or any particular condition. Cultural and spiritual context also matters when interpreting behavior and experiences. Focus on what has changed, how it affects daily life and whether the person seems frightened, confused or unsafe. Those concrete observations are more useful than trying to apply a label.
What may happen during a psychotic episode
A psychotic episode is a period when a person is actively experiencing psychosis-related symptoms or showing related changes in speech or behavior. A person may not recognize that a hallucination or delusion is not real. To them, the experience can feel convincing and can leave them frightened or distressed.
Changes may develop gradually. Family members may notice less specific changes in thoughts, perceptions, social connection or functioning before a more obvious crisis occurs. In young people especially, these shifts can be difficult to distinguish from typical developmental changes. Concerning changes do not establish a diagnosis, but they are a reason to seek professional assessment.
A limited emotional response does not necessarily mean the person is unaffected or unable to understand. Give them time to process what you say and avoid overwhelming them with questions or explanations.
Avoid treating a person’s experience as a debate to win. You do not have to agree with a belief to acknowledge that the person is upset and needs support. Keep the immediate goal practical: safety, calm communication and connection with appropriate help.
Why the cause should not be assumed
Psychotic symptoms can have many possible contributors, including mental health conditions, physical illness or injury, and substance use. Some physical illnesses or injuries, including brain injury and stroke, can sometimes contribute to psychotic symptoms. This is one reason a medical evaluation matters.
Hallucinations or delusions can sometimes be related to the direct effects of a substance, withdrawal or medication. Mental health conditions can also involve psychosis. None of these possibilities can be sorted out reliably through self-diagnosis, a conversation at home or an online symptom list.
Do not assume that unusual behavior has a psychiatric cause, and do not assume it has a medical or substance-related cause. A qualified medical professional can assess the full picture. Tell the clinician about recent changes in health, injuries, substance use, withdrawal and medication changes, but do not stop, start or change medication without guidance from the prescribing clinician.
The person’s cultural and spiritual background also belongs in that assessment. An experience or behavior should be understood in context rather than judged from a single isolated observation. Share context with the clinician, while leaving the cause and diagnosis to professional evaluation.
Choose the next step by safety level
Use safety—not a guess about diagnosis—to decide what to do next.
Immediate emergency help
Call 911 in a life-threatening emergency or when there is a risk that the person may harm themselves or others. If you are in the U.S. and suicide-related crisis support is needed, call or text 988. If safety is at risk, call 911 now.
Do not leave someone alone when it is not safe for them to be alone. Protect the person, yourself and others from immediate harm, and keep enough space to leave safely. Tell responders what you observe and what danger is present rather than trying to determine a diagnosis.
Prompt professional assessment
Psychotic symptoms should not be self-diagnosed or managed alone. Contact a qualified medical or mental health professional for an evaluation.
Planned follow-up for complex or unresolved concerns
When symptoms or their cause remain unclear after initial care, a more comprehensive review may help bring together mental health, medical, medication and family observations. A second opinion can be a collaborative way to clarify questions, not a judgment on the existing care team. Ask the current clinician what additional evaluation or consultation may be appropriate.
How family members can respond in the moment
Your approach can reduce added distress while help is being arranged. Remain as calm as possible, use simple and brief communication, and give the person time to respond. Disorganized speech or a limited response does not mean the person cannot understand you.
Try a response such as: “I can see this is upsetting. I’m here with you. What would help you feel safer right now?” Keep your voice low and your statements concrete. Let the person set the pace of the interaction when possible.
Respect personal space. Do not touch the person without permission, and do not crowd them if they seem suspicious or avoid eye contact. Describe specific changes you have observed rather than arguing about beliefs or assigning a diagnosis.
Offer choices when it is safe to do so, such as whether to sit in a quieter place or which trusted person to call. At the same time, focus first on immediate safety, including whether there is a risk of harm and whether it is safe for the person to be alone. If you cannot safely de-escalate the situation, call for emergency assistance.
What to communicate in an emergency
In the U.S., 988 provides suicide-related crisis support by call or text. Call 911 for a life-threatening emergency. When contacting emergency services about a possible psychotic episode, describe what you are observing and any immediate safety concern; do not assume or state a diagnosis.
Be concise and specific. You might share:
- what the person is saying or doing that concerns you;
- whether there have been threats of self-harm, harm to others or violence;
- whether the person can safely be left alone;
- whether there is access to a weapon or another immediate danger;
- when the change began and whether it became worse quickly; and
- relevant recent injury, illness, substance use, withdrawal or medication change, if known.
Tell responders that you are seeking medical help for a mental health crisis. If it is safe, explain to the person who unfamiliar responders are and that they are there to help. For immediate danger or a life-threatening situation, call 911.
Prepare for a professional evaluation
A clinician determines the cause of psychotic symptoms. You can make the evaluation more informative by bringing a short factual record. Family observations about when changes began and how they developed can help describe the presentation and course.
Prepare the following, if available:
- Observed changes: Write down specific examples of changes in perceptions, beliefs, speech, behavior, self-care, sleep, social connection or daily functioning.
- Timing: Note when changes began, whether they were gradual or sudden, and what was happening around that time.
- Safety concerns: Include any statements or actions involving self-harm, harm to others, inability to care for basic needs, severe agitation or aggression.
- Health context: List recent illnesses, injuries, medical events and any other relevant changes in health.
- Substances and medications: Record known substance use, possible withdrawal, prescribed medicines, over-the-counter products and recent medication changes. Do not change medication on your own.
- Medical records: Bring relevant medical records, current medication lists and prior evaluation information when possible.
Use plain descriptions rather than conclusions. Describe the words, actions, timing and functional changes you observed. Include the person’s own account when they are willing to share it, along with relevant cultural or spiritual context. This information helps the clinician consider the full picture without asking family members to determine the cause. Bring your observations and medical records to the evaluation.
What professional care may address
The plan depends on the person’s symptoms, possible contributors, preferences and circumstances.
Care may include therapy, family education and support, medication management, help with work or school, and case management. Family education can help relatives understand psychosis and build communication and problem-solving skills. Support for education or employment may also be part of a person’s broader goals.
When needs are complex, coordinated assessment can help the care team consider mental health, physical health, medications, substance exposure, family observations and daily functioning together. That does not replace individualized clinical judgment or guarantee a particular diagnosis or outcome.
Medication decisions should be individualized. Antipsychotic medications have potential benefits and risks. Discuss benefits, risks, side effects, costs and dosage preferences with the prescribing clinician rather than changing medication on your own.
It is reasonable to ask the care team: “What concerns are you evaluating?” “Are there coexisting health issues to consider?” “How can family members support the plan?” and “What should prompt urgent reassessment?” Use the appointment to clarify the plan with the clinician responsible for care.
Moving forward when concerns remain complex
Psychosis is serious enough to deserve professional evaluation, but it does not tell you by itself what is causing the symptoms or what the outcome will be. Start with the safety level: emergency help for immediate danger, prompt assessment for concerning symptoms, and organized follow-up when questions remain unresolved.
Concrete observations, a timeline of changes and relevant medical records can help a care team understand a complex situation. When concerns involve multiple possible contributors or unanswered questions, coordinated assessment and a second opinion may help clarify care needs. A second opinion is a collaborative review to support clearer questions and planning, not a promise of a different diagnosis or treatment. Mayo Clinic experts can be a resource for serious or complex medical challenges; suitability and next steps require individual discussion.
Frequently asked questions about psychosis
How is psychosis different from a diagnosis?
Psychosis is a group of symptoms, not a diagnosis by itself. A clinician needs to evaluate what may be causing the symptoms before a diagnosis or treatment plan can be made.
What should I do if someone may be having a psychotic episode?
Start with safety. Stay calm, use brief and simple language, respect personal space, and avoid arguing about beliefs or naming a diagnosis.
When does psychosis require emergency care?
Seek emergency help right away if there is risk of self-harm or harm to others, severe agitation, uncontrollable aggression, or threats of violence. In the U.S., call or text 988 for suicide-related crisis support and call 911 for a life-threatening emergency.
Can psychotic symptoms have causes other than a mental health condition?
Yes. They can be related to mental health conditions, physical illness or injury, substance use, withdrawal, or medication effects. That is why professional evaluation matters and self-diagnosis can be misleading.
What should we bring to a professional evaluation?
Bring a short record of what changed, when it started, how quickly it changed, any safety concerns, recent illness or injury, substance use, medication changes, and relevant medical records. Concrete observations are often more helpful than conclusions.
Why might a second opinion help with complex concerns?
A second opinion can be a collaborative review when symptoms, causes, or next steps are still unclear. It may help the care team consider mental health, physical health, medications, family observations, and other possible contributors together.
