About

The principle aim of the project is to analyze brain electrical activity and genetic information that will help identify the nature and cause of the disease schizophrenia. This effort should lay the groundwork for future treatment in schizophrenic patients.

Full description

There are several studies and hypotheses to be tested. This project includes a cross-sectional study design measuring brain waves, clinical symptoms, cognitive and functional ability, and genetic information in schizophrenic patients and normal controls. Subjects are expected to do a brain wave recording (EEG/ERP), role-play test designed to measure functionality and cognitive ability, and clinical symptom assessments. Expected duration of subject participation will be approximately 8 hours (about 2 visits). Outcome measures includes biomarkers, clinical symptoms and function, and genetic information.

Enrollment: 800 estimated patients

Sex: All

Ages: 14 to 62 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Male and Female between ages 14-62 (clinical assessment and blood draw only above 62)
• Ability to give written assent (subjects who are below the age of 18)
• Ability to give written informed consent (age 18 or above)
• Sufficient understanding of the study and risks (ESC score 10 or above)
• Subjects above age 62 will not participate in brain electrical activity measurements although they may still participate in clinical assessments and blood draw.

Exclusion criteria

• Inability to sign informed consent/assent
• Any major medical illness that may affect normal brain functioning. Examples of these conditions include, but not limited to, stroke, repeated seizure, history of significant head trauma, CNS infection or tumor, an other significant brain neurological conditions.
• Significant alcohol or drug use (substance dependence within 6 months or substance abuse within 1 month) other than nicotine or marijuana dependence.
• Woman who is pregnant (child bearing potential but not on contraceptive and missing menstrual period; or by self-report; or by positive pregnancy test).
• Can not refrain from using alcohol and/or marijuana 24 hours or more& cigarette smoking half and hour or more prior to experiments.
