Acute Psychosis
Acute psychosis is a medical emergency in which a person loses contact with reality, often abruptly. It can affect anyone, though it most commonly appears in late adolescence and early adulthood. Episodes can arise from an underlying mental illness, substance use, severe sleep deprivation, or certain medical conditions.
Key points
- Losing touch with reality shows up as hallucinations, fixed false beliefs, or speech and behaviour that no longer make sense.
- The affected person is usually unaware anything is wrong, so family members or carers often seek help first.
- Calming the episode safely with antipsychotic medicine comes first, with ongoing psychiatric care following once it settles.
What a psychotic episode looks like
The core features are hallucinations (hearing or seeing things that are not there), delusions (fixed false beliefs, such as being persecuted or having special powers), and severely disorganised speech or behaviour. The person is usually unaware that anything is wrong, which is why carers and family members are often the first to seek help.
How acute psychosis is treated
The priority is calming the episode safely and preventing harm. Antipsychotic medicines are the cornerstone of treatment. Haloperidol is a well-established option, valued for its rapid onset in acute settings. Longer-term management, including relapse prevention, falls under mental health care and typically involves ongoing psychiatric follow-up.
If someone is in immediate danger of harming themselves or others, call local emergency services or go to the nearest hospital emergency department without delay.
