NIMH Study 68 and Study 85

NIMH Study 68 (sites 18 and 131): Data and biomaterials were collected as part of a study examining people who did or did not abuse cannabis when they were adolescents and who either had developed schizophrenia or did not. Family history for psychiatric disorders, particularly the psychoses, was obtained on each individual and familial risk for schizophrenia was quantified. This project was supported by a grant (R01DA021576) to Lynn E. DeLisi, M.D., formally at New York University Langone School of Medicine and then at Harvard Medical School.

NIMH Study 85 (site 260): Data and biomaterials were collected as part of a study examining people who were at familial high-risk for schizophrenia based on having at least 2 relatives with illness within the family (at least one being a first-degree relative compared with controls who were at low familial risk for schizophrenia. Structural and functional MRI examining language processing were obtained on each participant and samples for DNA were stored in the NIMH repository. This project was supported by a grant (R21MH083205) to Lynn E. DeLisi at the Department of Psychiatry at Harvard Medical School. Scans were performed at Massachusetts Institute of Technology under the direction of Dr. Susan Gabrieli. These individuals were recruited from throughout the Boston and New England region. They received cognitive testing at The Beth Israel-Deakoness Medical Center.
