Baseline participation may take between one to two days (~7 hours for all study procedures).
Participants will be given paper and pencil and computer tests of memory, attention and logic, and interviews about their mood, thoughts and behaviors by a trained staff member at the UCLA Center for Cognitive Neuroscience, and an MRI scan at UCLA's Brain Research Institute.
The study also involves a review of medical records, to get information about birth and medical history, and an optional blood or saliva sample.
Some of the study procedures will be repeated at 2 follow-up timepoints. All procedures will be explained carefully and all participation is completely VOLUNTARY. You may withdraw from the study at any time. There is no financial obligation on the part of the participant.
