Eligibility

Inclusion Criteria:

Patients:

• current DSM-5-defined diagnosis of a schizophrenia or bipolar disorder. A best estimate diagnostic approach will be utilized in which information from the Diagnostic Interview for Genetic Studies (DIGS) is supplemented by information from family informants, psychiatrists, and medical records to generate a diagnosis as needed

• no alcohol or substance abuse during the last 6 month

• no current substance-induced psychotic disorder or a psychotic disorder due to a general medical condition determined by DSM-5 criteria

• ages 18 to 30 years old;

• any race

• competent and willing to sign informed consent

• within 5 years from the disease onset.

Siblings:

• have the same biological parents as their PSD sibling

• any race

• no current or past history of psychotropic medication usage

• no alcohol or substance abuse during the last 6 months

• competent and willing to sign informed consent;

• ages 18 to 30 years old.

Healthy controls:

• matched for age to PSD patients

• no current or past history of psychotropic medication usage

• no prodromal symptoms and no family history of PSD

• no alcohol or substance abuse during the last 6 months

• competent and willing to sign informed consent.

• all attempts will be made to recruit controls with similar parental SES as patients. However, given that PSD are both a neurodevelopmental and familial disorder, exact matching for educational level or IQ may neither be possible nor desirable.

• any race

• no current or past history of psychotropic medication usage

• no alcohol or substance abuse during the last 6 months

• must not have met DSM-5 criteria for current alcohol or drug dependence in the last 6 months;

Intervention

Diagnostic Test:
• Cognitive Function Assessments
The NIMH-Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) is a consensus battery that is considered state-of-the art in the evaluation of cognitive skills for schizophrenia research.(Burton et al., 2013, Harvey, 2014) The complete cognitive battery takes about one hour to administer, and is comprised of 10 subtests measuring seven essential domains of function, with very good reliability and validity.(Nuechterlein 2008, August et al., 2012) The MATRICS subtests have been incorporated into the cognitive battery described below, with supplementary subtests included where indicated within each domain.
