Biomarkers in Healthy Adults and Siblings of People with Schizophrenia (BHASS) study

What is the purpose of the study?

We are interested in how the immune system influences the brain. We are seeking volunteer research participants to learn about how immune markers in the blood relate to cognition, behaviour and brain activity.

Would the research project be a good fit for me?

The study might be good for you if:

  • You are between the ages of 18-60 and you are a healthy adult with or without a

sibling who has a diagnosis of schizophrenia or schizoaffective disorder

  • You DO NOT have a personal history of schizophrenia, seizures, substance abuse or

dependence (within past 3 years), head injury or loss of consciousness, central nervous system infections

What would happen if I took part in the research project?

If you decide to take part you would visit Neuroscience Research Australia to complete the following:

  • Perform cognitive tests and questionnaires (within 2 hours)
  • Provide a blood sample
  • Receive a short medical examination including a visual eye, nose, and throat exam,

lungs and heart (using stethoscope) exam, body temperature, blood pressure, and

brief medical history

  • Receive an MRI scan (approx. 1 hr) which includes performing computer-based

cognitive tests

Will I be paid to take part in the research project?

Your participation in this study may have associated expenses. Reimbursement will be provided for your time and for out-of-pocket expenses, such as travel to the centre.
