Query: Orthomolecular Hogwash

I'm disappointed to see this book still sold. This book covers an approach which Dr. Abram Hoffer and others developed in the 1950s, but which by the 1970s was proven to be fruitless. The work of Dr. Hoffer and others is discussed in detail in the American Psychiatric Association Task Force Report, July 1973, which points out methodological flaws in the early work and reviews later studies which failed to show any benefit for such treatments.In recent years, new medicines, with improved side-effect profiles and techniques to overcome problems with social and occupational functioning, have been well proven advances for the treatment of schizophrenia. Early intervention programs should prevent some of the serious dysfunction of the disease.Serious illnesses like schizophrenia require proven treatments. Vitamin treatments as "alternative" therapy for schizophrenia should not be recommended.
