Overview
Schizoaffective disorder is challenging to diagnose, as symptoms closely resemble other mental health conditions.
The first step in making a diagnosis is speaking up. If you’re concerned about a friend or loved one who shows symptoms of schizophrenia and a mood disorder, have a conversation with that person. It can be difficult for someone who experiences a mental health condition to reach out for help on their own or know that they need help. Calmly share your concerns and offer support. It helps to surround yourself with people you know and trust so you can get the care you need.
A healthcare provider who specializes in mental health conditions like a psychologist or a psychiatrist will diagnose schizoaffective disorder.
Schizoaffective disorder test
There are no lab tests available to diagnose schizoaffective disorder. If you see a primary care physician first, they may offer tests to rule out medical conditions with similar symptoms before recommending you visit a mental health specialist.
How does a psychiatrist or psychologist diagnose schizoaffective disorder?
Mental health professionals use specially designed interview and assessment tools to diagnose mental health conditions like schizoaffective disorder. They’ll listen to you (or a loved one) describe your symptoms. They’ll also take note of your speech and behavior.
Providers determine if your symptoms and behaviors match a specific mental health condition in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The American Psychiatric Association DSM-5 is the reference book for mental health conditions.
The diagnostic criteria or the information that the DSM-5 describes for schizoaffective disorder include:
- A period of uninterrupted mental health symptoms that affect your mood (mania or depression) and includes symptoms of schizophrenia (delusions, hallucinations, disorganized speech and behavior, etc.).
- Hallucinations and delusions that last for at least two or more weeks without mood symptoms.
- Symptoms that affect your mood are present during the majority of the time you experience symptoms.
- No evidence of a substance use disorder or medications that may cause your symptoms.
