Read our Schizophrenia research guide →Researchers want to understand what happens in the brains of people with schizophrenia by studying two key brain chemicals called glutamate and GABA. This study will compare these brain chemicals in three groups: people diagnosed with schizophrenia, their healthy relatives, and healthy people with no family history of schizophrenia. By looking at blood tests, brain scans, and genetic information, the researchers hope to find clues about why schizophrenia develops.
Schizophrenia is a serious mental health condition, but doctors don't fully understand what causes it or why some people develop it while others don't. This study aims to find biological markers—measurable signs in the blood, brain, and genes—that could help explain the condition and eventually lead to better treatments.

You will have one or more study visits where you'll provide a small blood sample (about 2 tablespoons) for testing, complete a brain imaging scan (MRI or similar), and answer questions about your medical and psychiatric history through interviews and rating scales. The researchers will also analyze your genes from the blood sample. All three groups—patients, relatives, and healthy controls—will go through the same procedures.
