Beskrivelse
Inclusion Criteria:
- Males or females between 18-26 years of age, AND currently enrolled in the Parent Project (R01MH067924)
Exclusion Criteria: (these exclusion criteria are outlined in the Parent Project)
- Head injury with loss of consciousness over an hour.
- A vision problem or eye movement problem (such as lazy eye, double vision, blurred vision, or color blindness).
- A learning disability and/or ever had an Individualized Education Plan (IEP) in school.
- Significant neurological or metabolic illness: Epilepsy, Meningitis, Encephalitis, Diabetes, Huntington's disease.
- Diagnosed with a psychiatric disorder.
- Participants with, or with a first degree relative, having a DSM IV Axis l psychiatricdisorder.
- Metal implants or ferromagnetic objects contained within the body which may interfere with the MRI scan (but not limited to, those with a pacemaker, presence of metallic fragments near the eyes or spinal cord, or cochlear implant.) Dental fillings do not present a risk for MRI. If there is a possibility of metal being present in the participant's body, the participant will be excluded from the study.
- Weight more than 250 pounds.
- Claustrophobia or uncomfortable in small spaces.
- <70% on the Achenbach scale (either from Youth Self Report (YSR) or Adult Self Report (ASR)).
- IQ < 80 or IQ > 130.
- Pregnancy or lactation, lack of effective birth control during 15 days before the scans.
- Currently employed as radiation worker; or participation in radioactive drug research protocols within the previous year such that the total cumulative annual radiation dose (i.e., from participation in the previous radioactive drug study [studies] and this study) would exceed the radiation dose limits specified in the FDA regulations (i.e., 21 CFR 361.1) that govern the research use of [C-11]UCB-J
- History of drug or alcohol abuse (from parent study eligibility).

Eksperimentel: PET Imaging Supplemental Component
Adult participants enrolled in the parent study, will be given the option to be a part of the PET imaging supplemental project.
Maximum enrollment is 60 adult participants.
Interested participants will be consented into the PET portion, and will have a single PET scan (as outlined in the Study Description section).
|
[11C]UCB-J (~ 15 mCi and ≤ 6μg) will be injected as a slow intravenous bolus.
Following an intravenous bolus injection of [11C]UCB-J, the participants will be positioned in the scanner for a low dose CT scan (for attenuation correction) fifty-five minutes after the [11C]UCB-J injection, and emission data will be collected.

Non-invasive quantification of synaptic pruning
Tidsramme: The PET-CT scan will be within approximately 30 days of the parent study MRI.

1. Age-related changes in synaptic density through young adulthood o Cross-sectional age-related (18-26 years of age) changes in synaptic density via SUVR quantified within the dorsolateral prefrontal cortex. |
The PET-CT scan will be within approximately 30 days of the parent study MRI.

Non-invasive quantification of synaptic pruning
Tidsramme: The PET-CT scan will be within approximately 30 days of the parent study MRI.

2. Within-subject associations of synapse density to MRI-derived measures of brain membrane byproducts o Synaptic density, based on SUVR modeling of [11C]UCB-J acquisitions, will be compared to ultra-high field (7 Tesla) [31P]MRSI measurement of membrane phospholipid levels obtained from the same participants. |
The PET-CT scan will be within approximately 30 days of the parent study MRI.
