Schizophrenia is diagnosed through a detailed clinical assessment. There is no single blood test or scan that can independently diagnose the condition.
What an assessment may include
- Symptoms and how long they have lasted
- Medical and psychiatric history
- Family history
- Medication history
- Substance use
- Changes in daily functioning
- A mental-state assessment
Ruling out other causes
A clinician may consider other possible causes of psychotic symptoms, such as other medical conditions, medicines or substance use, before reaching a diagnosis.
Why diagnosis matters
An accurate assessment helps identify the most appropriate treatment and rule out other conditions that may cause similar symptoms.
Preparing for the appointment
- Write down the symptoms and when they started
- List current and past medicines
- Note any family history of mental-health conditions
- Consider bringing a family member or trusted person
