Attention-defi cit/Hyperactivity Disorder and Integrative Approaches Asma J. Sadiq, MD A Brief History of Medicine “I have an earache.” 2000 B.C. “Here, eat this root.” 1000 A.D. “That root is heathen, say a prayer.” 1850 A.D. “That prayer is superstition, drink this potion.” 1940 A.D “That potion is snake oil, swallow this pill.” 1985 A.D. “That pill is ineffective, take this antibiotic.” 2000 A.D. “That antibiotic is artifi cial, here, take this root.” —Anonymous ncreasing numbers of Americans are turning to complemen- tary and alternative medical therapies (CAM) for themselves Iand their children. A host of explanations for this increase has been surveyed and researched. A recent study reported 54% of parents using CAM therapies for their children, but only 11% ever discussing them with their pediatricians. The most impor- tant attraction of CAM therapies for parents is the belief that they are “a more natural therapy” and that they have greater control over treatments. Dissatisfaction with the process or the results of conventional care was noted in a small but increasing number within the population studied.1 Concerns regarding side effects and long-term use of medications are also factors fueling this quest, particularly in the case of children diagnosed with attention-defi cit/hyperactivity disorder (ADHD). Is this trend toward holistic care a “fad” or just a rebalancing of the medical pendulum, as it equilibrates itself with a new dynamic tension? We see the increasing use of naturopathy, homeopathy, acupuncture, botanical medicine, chiropractic, and mind-body medicine.
