A pilot study on the metal levels in the hair of hyperactive children.
The concentration of a number of metals has been determined in the hair of sixty eight children who have been described as 'hyperactive'. These are compared with a control group. The most important findings would appear to be a raised level of manganese and a reduced level of zinc in the hyperactive children. The possible significance of this is discussed. A high manganese level in learning disabled children has also recently been reported and may be of direct relevance to the present study.
