When reality starts to feel unfamiliar, it can be difficult to explain what is happening. Someone may hear or see things other people do not, feel watched, find connections that others cannot see, or become very confused. These experiences need a calm response and prompt professional assessment, not an argument about whether they are “real enough”.
What a first episode can look like
Psychosis describes experiences such as hallucinations, delusions or markedly disorganised thinking. It can occur with different mental health conditions, after substance use, alongside physical illness or for other reasons. A first episode is not a diagnosis by itself. It is a reason to seek an assessment that considers the whole picture. NHS guidance on diagnosis describes questions about symptoms, health, medicines, alcohol or drugs and family history.
Changes may be gradual. A person might withdraw, struggle to concentrate, sleep differently or become more suspicious. Or the change may be sudden. Do not assume that an experience is attention-seeking, a spiritual failure or something a person can reason their way out of.
What to do today
Ask for an urgent medical or mental health assessment, especially if this is new. In the UK, a GP can arrange referral and some areas have Early Intervention in Psychosis teams. These teams support people after a first episode with assessment, medicine where appropriate, talking therapies and practical support. NHS treatment information explains this service model. Elsewhere, ask a primary-care clinician or local mental health service how to access urgent assessment.
Bring a short timeline: when changes began, sleep, medicines, alcohol or other substances, physical symptoms and anything that has changed at home, work or study. If the person agrees, a trusted person can help communicate this information. Avoid using alcohol, drugs or unprescribed medicine to try to settle the experience.
How to support someone without escalating things
Speak calmly, use short sentences and ask what would help them feel safer. You can say, “I can see this feels frightening. Let us get help together.” Avoid debating a belief, teasing them or promising to keep a situation secret if safety is at risk. Offer practical help such as sitting with them while they call for care, arranging transport or reducing a noisy, crowded environment.
Support does not mean taking over every decision. If they can participate safely, ask what they want shared with clinicians. You can also look after your own limits and seek guidance as a carer.
When emergency help is needed
Use local emergency services or the nearest emergency department now if there is imminent risk of harm, severe confusion, inability to care for basic needs, dangerous behaviour, a medical emergency, or threats to harm self or others. If you are unsure how urgent it is, contact an urgent health service for local advice. Do not try to restrain someone unless trained responders say it is necessary for immediate safety.
Early help is not a verdict
Prompt assessment can make a real difference, but it does not predict a person's future or determine their identity. Diagnosis may take time and can change as clinicians learn more. The useful next step is simple: take new psychotic experiences seriously and connect with care.
Prepare for the first conversation
It can help to ask the service what happens next, who will coordinate care and how family or friends can be involved with consent. Write down questions rather than relying on memory during a stressful appointment. Recovery often includes practical goals as well as symptom support, such as returning to routines, housing, work, study and relationships.
