Mental illness, its forms, and the progress being made in its treatment are the focus of this program. First, Dr. David Pickar, of the National Institute of Mental Health, provides information on schizophrenia and its treatment. A patient with schizophrenia who has a history of suicide attempts and has benefited from drug therapies is profiled. Then, Dr. Frederick Goodwin, formerly of the NIMH, shares his knowledge of depression, an illness that affects millions of American adults. Of this group, most could benefit from medication, but only a fraction actually seek treatment. The program also explores the temporary chemical changes in the brain during winter, which can lead to seasonal affective disorder. (23 minutes)
