Barbara A. Cornblatt

Barbara A. Cornblatt is Professor of Psychiatry and Molecular Medicine at Hofstra Northwell School of Medicine. She is known for her research on serious mental disorders, with a specific focus on psychosis and schizophrenia. Her efforts to find treatments to help youth with mental illness led to the development of the Recognition and Prevention Program, which she founded in 1998.

Cornblatt was awarded the Joseph Zubin Memorial Fund Award in 1996. She served as president of the Society for Research in Psychopathology (2000–01).

Biography
Cornblatt received an MBA degree in industrial psychology at Baruch College, City University of New York in 1977 and a Ph.D. in experimental psychology from New School University in 1978.

Cornblatt's research program, including projects focusing on cognitive behavioral social skills training for youth at risk of psychosis, predictors and mechanisms of conversion to psychosis, and characterization of prodromal schizophrenia, has been funded by the National Institute of Mental Health of the National Institutes of Health. She worked on North American Prodrome Longitudinal Study (NAPLS-1), a large multisite longitudinal study focusing on the earliest stages of psychotic illness, with prominent clinical psychologists and psychiatrists including Tyrone Cannon, Elaine F. Walker, and Thomas McGlashan.

Research
Towards a Psychosis Risk Blood Diagnostic for Persons Experiencing High-Risk Symptoms: In this study, the researchers looked at different analytes found in human blood plasma. These plasma analytes reflected inflammation, oxidative stress, hormones, and metabolism. It was discovered that individuals who are at a high-risk for psychosis have high levels of inflammation, oxidative stress, and hormone imbalances.

Cortisol Level and Risk for Psychosis: Researchers tested the cortisol contents of saliva in 256 individuals. It was discovered that patients that were at a higher risk of psychosis, or already had the diagnosis, had increased cortisol levels. This study suggests the need for future research focusing on the hormone levels of individuals with, or at risk of, psychosis.

Functional development in clinical high risk youth: Prediction of schizophrenia versus other psychotic disorders: This study was a follow-up study involving participants from the NAPLS-1 study. Researchers checked for three different signs in their patients: psychosis-risk symptoms present at baseline (these plasma analytes reflected inflammation, oxidative stress, hormones, and metabolism), onset of psychosis during the two and a half-year follow-along period of NAPLS-1, and psychotic disorder diagnosis from the Diagnostic and Statistical Manual of Mental Disorders (DSM). The study showed that people in early adolescence who showed poor social indicators were four times as likely to develop schizophrenia. Those in their late adolescence with poor social indicators were five times as likely to develop schizophrenia.
