RAP Study: Risk Assessment for Psychosis – Healthy Adult Volunteers

STUDY BASICS

Are you a healthy adult aged 19-35 years old, with no history of major psychiatric or neurological disorders, drug or alcohol abuse, or head injury? If so, you may be able to take part in a brain imaging and sleep research study. Compensation provided.

STUDY PURPOSE

About 3% of people will experience psychosis at some point in their lives. Symptoms of psychosis can include hearing voices, having beliefs that other people do not share, or having difficulty thinking clearly. In some cases, psychosis can be a symptom of a mental illnesses like schizophrenia or bipolar disorder. Experts are not sure exactly what causes psychosis and related mental illnesses. The purpose of this study is to better understand psychotic episodes by studying brain activity while awake and asleep of people who are and are not at an elevated risk for mental illness. Researchers hope their findings will lead to better ways to identify and treat mental illness.

COULD THIS STUDY BE RIGHT FOR YOU?

• Ages 19-35
• No history of major psychiatric disorder, drug or alcohol abuse, head injury, or neurological disorders
• Able and willing to undergo MRI scanning and stay overnight in a sleep lab for study procedures

WHAT PARTICIPANTS CAN EXPECT

Participation involves study visits at baseline and then once yearly for up to 2 years. After screening procedures to confirm eligibility, the following study procedures will be done: interviews about your background, feelings, daily functioning, and sleep habits; tests of your attention, concentration, and problem solving; sleep assessments at home and overnight in the laboratory, including a high-density electroencephalography (hd-EEG), which is a way to measure the natural activity of the brain; and magnetic resonance imaging (MRI) scan, which takes pictures of the brain. Both hd-EEG and MRI procedures are not invasive and do not involve radiation.
