In 1987, researchers at the University of Colorado and Yeshiva University studied a group of children who were being evaluated for school failure. Those receiving medication for hyperactivity had a history of more than ten ear infections. By comparison, only 20% pf non-hyperactive children had this many infections.

Then in July 1895, William Shaw, Ph.D., and colleagues of the Children's Mercy Hospital and the University of Missouri School of Medicine, Kansas City reported finding fungal metabolites in the urine of autistic children. They also noted a reduction in these metabolites and improvement of these children following therapy with anti-fungal drugs.

In his book, Help for the Hyperactive Child, Dr. Crook explores how antibiotics and other drugs can lead to leaky gut syndrome in children -- which can lead to chronic health and attention problems. The book offers practical steps to eliminating the culprits and getting your child on the road back to good health.
