Childhood hyperactivity and caffeinated colas

At the May 23rd, 2005 annual meeting of the American Psychiatric Association held in Atlanta, Dr. Alan Hirsch, the director of the Smell and Taste Treatment and Research Foundation and assistant professor of both neurology and psychiatry at Rush Medical College in Chicago, presented his findings on a double-blinded study of 20 first-grade students and found that on days when students drank up to 12 ounces of caffeinated colas, they demonstrated more behavior problems compared to days when they did not consume the soft drinks or when they consumed caffeine-free colas.
