Abstract
OVERVIEW:

Complementary and Alternative Medicines (CAMs) are frequently given to children and adolescents for reputed benefits in the treatment of hyperkinetic and concentration disorders such as Attention Deficit Hyperactivity Disorder (ADHD). In such vulnerable populations high quality evidence is required to support such claims.

AIMS:

The aim of the paper is to assess the current evidence of herbal and nutritional interventions for ADHD using a systematic search of clinical trials meeting an acceptable standard of evidence.

METHODS:

PubMed, PsycINFO, Cochrane Library and CINAHL were searched up to May 26th, 2011 for randomised, controlled clinical trials using CAM products as interventions to treat ADHD. A quality analysis using a purpose-designed scale, and an estimation of effect sizes (Cohen's d) where data were available, were also calculated.

RESULTS:

The review revealed that 16 studies met inclusion criteria, with predominant evidentiary support found for zinc, iron, Pinus marinus (French maritime pine bark), and a Chinese herbal formula (Ningdong); and mixed (mainly inconclusive) evidence for omega-3, and l-acetyl carnitine. Current data suggest that Ginkgo biloba (ginkgo), and Hypercium perforatum (St. John's wort) are ineffective in treating ADHD.

CONCLUSION:

The research suggests only some CAMs may be beneficial in ADHD, thus clinicians need to be aware of the current evidence. Promising candidates for future research include Bacopa monniera (brahmi) and Piper methysticum (kava), providing potential efficacy in improving attentional and hyperkinetic disorders via a combination of cognitive enhancing and sedative effects.
