Psychotic Disorders

Key facts

• Psychotic disorders are serious mental health conditions that disrupt a person's grip on reality, affecting roughly 3 in 100 people at some point in life.
• Positive symptoms are hallucinations (most often hearing voices), delusions (fixed false beliefs) and disorganised thinking; negative symptoms include flat emotions, social withdrawal and loss of drive.
• Antipsychotic medicines such as chlorpromazine are the cornerstone of treatment, working by modulating dopamine pathways; most people need to stay on treatment long term to prevent relapse.
• Sudden worsening, or any thought of harming oneself or others, is a medical emergency.

What psychosis actually looks like

The clearest signs are the positive symptoms: hallucinations, delusions, and thinking so disorganised it becomes hard to follow a conversation or plan daily tasks. Negative symptoms are subtler but equally disabling, flat emotion, withdrawal, and difficulty starting or sustaining activity. Schizophrenia is the best-known condition, but brief psychotic episodes, schizoaffective disorder, and psychosis linked to mood disorders all fall under this umbrella.

How antipsychotics fit in

Antipsychotic medicines remain the backbone of treatment. Older agents such as chlorpromazine were the first to bring positive symptoms under reliable control and are still used where cost or access matters. They work by modulating dopamine pathways in the brain, and most people stay on treatment long term to prevent relapse, so a dose and formulation that is tolerable matters as much as the choice of drug.

When to seek help

Seek urgent medical help if symptoms return or worsen suddenly, or if a person expresses thoughts of harming themselves or others. A first episode of psychosis always needs prompt specialist assessment.
