Johnson Compounding and Wellness Center, in Waltham, will present a free seminar series this spring that explores the use of integrative medicine in psychiatry and mental-health treatment. The seminar will address the limitations of psychotropic medications and explore why the current trial-and-error, “polypharmacy” approach to the treatment of mental illness also may be limited. Sessions will take place from 9 a.m. to noon on two Saturdays, April 14 and May 5. Dr. James Greenblatt, a dually board-certified child and adult psychiatrist, will present.

The seminar will cover evidence-based research on nutritional therapies used to treat mental illness and emphasize nutritional factors that can be assessed through laboratory testing. “ADHD, anxiety, anorexia, depression, autism and other mental-health disorders often have dietary or biological causes that can be treated effectively once the underlying issues are known,” says Greenblatt. “Such factors as intestinal pathogens, inadequate protein consumption, food allergies and nutritional deficiencies, environmental toxins, gastrointestinal disorders and enzyme deficiencies can all contribute to improper brain chemistry.”

Greenblatt is the founder and medical director of Comprehensive Psychiatric Resources, Inc., a multidisciplinary psychiatric group practice in Waltham. The seminar series is free to the public. For professionals interested in CEUs, $25 will be collected on-site for each session.

Johnson Compounding and Wellness Center is located at 577 Main St,. Waltham. For more information, call 781-647-0066 or visit ComprehensivePsychiatricResources.com.
