Brief Summary
This study is part of a larger overall study that seeks to characterize clinical and pharmacological neuroimaging biomarkers. The purpose of this registered protocol is understand the effect of emotio...
Detailed Description
Cognition rarely occurs in the 'real world' in isolation, and typically occurs under emotional influences that may alter how cognition occurs. Understanding these motivational and cognitive interactio...
Eligibility Criteria
Inclusion
- For BOTH Non-Healthy Controls and Healthy Controls:
- Right-handed as determined by the Edinburgh handedness questionnaire (Oldfield, 1971).
- Premorbid IQ\>70 determined by WAIS similarities and matrix reasoning subtests; Any history indicating learning disability, mental retardation, or attention deficit disorder will exclude the subject from participation.
- Must speak or read English at least 8th grade level or higher and to complete study evaluations.
- Must have intact vision or vision that can be corrected by glasses or contact lenses (corrected 20 20/20).
- Must be able to tolerate enclosed spaces \*\* only if participating in MRI portion.
- Female subjects must be postmenopausal for a least 1 year, surgically sterile, or using a reliable method of contraception at screening. Reliable methods of contraception include double-barrier methods (e.g. condom and diaphragm, condom and foam, condom and sponge), intrauterine devices, or hormonal birth control methods. Women with positive serum pregnancy results at screening or self-reporting of pregnancy will be excluded from the study. \*\* only if participating in MRI portion.
- Must be free of metallic foreign objects in body, such as aneurysm clips or pacemakers, or a questionable history of metallic fragments \*\* only if participating in MRI portion.
- For Non-Healthy Controls Participants:
- Adult patients from the community meeting diagnostic criteria for schizophrenia, schizoaffective disorder, psychosis at risk syndrome, Major Depressive Disorder or autism spectrum disorders.
- Young adults (16-21) who are at risk of developing schizophrenia (have "prodromal schizophrenia") may be involved in the study.
Exclusion
- For Healthy Controls:
- Evidence or history of serious medical or physical conditions, including severe endocrine disorder (Cushing's, Lupus), heart disorder (past history of heart attacks, angina), or other major systemic medical conditions (kidney, MS, CP, blindness, serious physical disability).
- Neurological conditions that might confound the results, including past stroke, seizures, dementia, brain tumor, brain surgery, neurological disease, head injury, or severe concussion (lasting \>2 minutes in their life).
- Individual not larger than 55" around shoulders and widest part of chest (approx. 250lb limit) \*\* only if participating in MRI portion.
- Any other condition that is contra-indicated for fMRI if selected to participate in fMRI portion as determined by the MRRC safety screen. \*\* only if participating in MRI portion.
- Meeting current diagnostic criteria for any DSM-IV Axis I psychiatric disorders, determined by SCID-NP / MINI interviews.
- First-degree relative with Axis I DSM-IV disorder.
- Regular use of psychoactive drugs including anxiolytics and antidepressants.
- Meeting current DSM-IV abuse and/or dependence diagnostic criteria for other substances, other than nicotine in the past 6 months as determined by SCID-NP / MINI interviews (excluding caffeine).
- For Non-Healthy Controls:
- Medical. Evidence or history of serious medical or physical conditions, including severe endocrine disorder (Cushing's, Lupus), heart disorder (past history of heart attacks, angina), or other major systemic medical conditions (kidney, MS, CP, blindness, serious physical disability).
- Neurological conditions that might confound the results, including past stroke, seizures, dementia, brain tumor, brain surgery, neurological disease, head injury, or severe concussion (lasting \>2 minutes in your lifetime).
- Individual not larger than 55" around shoulders and widest part of chest (approx. 250lb limit) \*\* only if participating in MRI portion.
- Any other condition that is contra-indicated for fMRI if selected to participate in fMRI portion as determined by the MRRC safety screen. \*\* only if participating in MRI portion.
- Meeting current diagnostic criteria for primary DSM-IV anxiety, depression or ADHD, determined by SCID-NP / MINI interview due to possible effects on cognition.
- Medication change within the past 2 weeks to avoid transient effects of medication regiment change; medication type and dose will be carefully recorded and used as a covariate in all analyses. Of note, if patients are not on medication (but are clinically stable) they will be invited to participate.
- History of any substance dependence disorder meeting DSM-IV criteria with the exception of nicotine and caffeine in the past 6 months. Meeting DSM-IV abuse and/or dependence diagnostic criteria for other substances in the past 6 months as determined by SCID / MINI interviews (again excluding caffeine and nicotine). Study will exclude for Specific Patterns of Substance Use. In addition, the study will exclude for use of stimulants, alcohol or heavy continued substance use defined as at least 3+ days per week for the duration of the last 6 months. In particular, we will not exclude for sporadic use of cannabis (defined as 3 or fewer marijuana cigarettes per week). Also, the study will exclude if a participant reports heavy habitual marijuana use, which we define more than 3 marijuana cigarettes per week over at least 90% of the weeks during a period of 6 months or more. Patterns of drug class, use pattern, frequency and history as well as the urine toxicology on the day of the assessment as well as all longitudinal followups will be assessed.
