Dr. Medalia is an international leader in the field of psychiatric rehabilitation, who focuses on the treatment of neuropsychological disorders in psychiatric illness. She developed the widely used NEAR (Neuropsychological & Educational Approach to Remediation) model to help people with mental illness improve their thinking skills in such areas as attention, memory, processing speed and problem solving. She lectures and consults to agencies worldwide and conducts training workshops for clinicians who want to learn how to provide cognitive remediation to psychiatric patients. Dr. Medalia works with policy makers, researchers, clinicians, families and patients to bring awareness about the impact of cognitive dysfunction on recovery. In order to facilitate greater awareness about cognition in the rehabilitation field, she started the largest conference on this topic, Cognitive Remediation in Psychiatry, which takes place the first Friday in June in New York City.
