Understanding Psychosis and Schizophrenia: Early Signs and When to Get Help
This page reflects our understanding of mental health topics as of 2026. If you are reading this at a later date, some details may no longer be current, so please verify anything important against up to date sources. If you notice anything that needs updating, we would welcome you letting us know.
If someone is experiencing hallucinations, severe confusion, or beliefs that put them or others at risk, or talks about suicide, call 911 or go to your nearest emergency department. You can also call or text 9-8-8 at any time. Early psychosis intervention programs across British Columbia accept referrals and can be reached through your family doctor or local health authority.
Psychosis describes a set of experiences in which a person loses some contact with shared reality. It can involve hallucinations, such as hearing voices others do not hear, and delusions, which are strongly held beliefs that do not match reality, such as believing one is being followed or controlled. Psychosis is a symptom rather than a single illness. It can occur with schizophrenia, bipolar disorder, severe depression, substance use, medical conditions, or extreme stress and sleep loss. Schizophrenia is a specific condition in which psychotic symptoms persist and affect functioning over time. Psychosis often first appears in the late teens to mid twenties. Early help makes a significant difference.
What Early Signs Can Look Like
Psychosis often develops gradually. Early changes, sometimes called the prodromal phase, may include:
- Withdrawing from friends and family, similar to not wanting to see friends.
- A drop in school or work performance.
- Trouble concentrating or thinking clearly.
- Suspiciousness or unease around others.
- Changes in sleep, often sleeping very little.
- Strong or unusual ideas, or preoccupation with new beliefs.
- Feeling that things are strange or changed, or detached from reality.
- Hearing faint sounds or whispers, or seeing shadows.
- Neglecting hygiene or self-care.
Later signs may include clear hallucinations, fixed delusions, disorganized speech or behaviour, and reduced emotional expression or motivation.
Why It Happens
Psychosis arises from a combination of genetic vulnerability, brain development, and environmental stress. Family history of psychosis increases risk. Factors such as childhood trauma, migration and discrimination, urban upbringing, and heavy stress are associated with higher rates. Cannabis use, especially high-potency products and use starting in adolescence, is strongly linked with psychosis in vulnerable people, as described on the page about cannabis and mental health. Stimulants and other drugs can also trigger psychotic episodes. Severe sleep deprivation and certain medical conditions can cause psychosis too.
Psychosis can also occur during mania in bipolar disorder, as explained on the page about bipolar I disorder, or during severe depression. A careful assessment helps identify the cause and the best treatment.
Families often notice changes before the person does. Because insight can be affected by psychosis itself, the person may not see their experiences as symptoms. Calm, non-judgmental conversations that focus on specific concerns, such as sleep or stress, often work better than arguing about beliefs.
What It Is Not
- Not the same as split personality. Schizophrenia does not involve multiple personalities.
- Not a sign that someone is dangerous. Most people with psychosis are not violent and are more likely to be victims of harm.
- Not always schizophrenia. Psychosis has many possible causes, and some episodes do not recur.
- Not untreatable. Many people recover well, especially with early intervention.
When and How to Get Help
Seek help promptly if you or someone you know shows early warning signs, especially changes in thinking, perception, or behaviour lasting more than a few days. A family doctor can assess and refer to early psychosis intervention programs, which offer coordinated care for young people and adults experiencing a first episode. Treatment usually includes antipsychotic medication managed by a psychiatrist, psychoeducation, cognitive behavioural therapy for psychosis, family support, and help returning to school or work. Reducing cannabis and other substance use, and protecting sleep, support recovery. Early treatment is linked with better long-term outcomes.
