Due to an enthusiastic public response, Johnson Compounding and Wellness Center, in Waltham, is extending its free seminar series on Integrative Medicine for Mental Health. Sessions will take place at Johnson Compounding and Wellness from 9 a.m. to noon on two Saturdays, May 5 and June 16. Dr. James Greenblatt, medical director of Comprehensive Psychiatric Resources, Inc., in Waltham, will present.

The May 5 session will address obsessive-compulsive disorder (OCD) and anxiety disorders; the June 16 session will focus on depression and mood disorders. The seminars cover evidence-based research on nutritional therapies used to treat mental illness and 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.”

The free seminars are open to the public. CEUs are offered to social workers, psychologists and licensed mental health counselors for a $25 fee per seminar. Space is limited; pre-registration is recommended at ComprehensivePsychiatricResources.com/category.php?category_id=65.

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