Can nutritional supplements help mentally retarded children? an exploratory study.

Abstract

To explore the hypothesis that mental retardations are in part genetotrophic diseases (diseases in which the genetic pattern of the afflicted individual requires an augmented supply ofone or more nutrients such that when these nutrients are adequately supplied the disease is ameliorated), we carried out a partially double-blind experiment with 16 retarded children (initial IQs, -17-70) of school age who were given nutritional supplements or placebos during a period of 8 months. The supplement contained 8 minerals in moderate amounts and 11 vitamins, mostly in relatively large amounts. During the first 4-month period (double-blind) the 5 children who received supplements increased their average IQ by 5.0-9.6, depending on the investigator, whereas the 11 subjects given placebos showed negligible change. The difference between these two groups is statistically significant (P < 0.05). Durin the second period, the subjects who had been given placebos in the first study received supplements; they showed an average IQ increase of at least 10.2, a highly significant gain (P < 0.001). Three of the five subjects who were given supplements for both periods showed additional IQ gains during the second 4 months. Three of four children with Down syndrome gained between 10 and 25 units in IQ and also showed physical changes toward normal. Other evidence suggests that the supplement improved visual acuity in two children and increased growth rates. These results support the hypothesis that mental retardations are in part genetotrophic in origin.About 30 years ago Williams and coworkers (1, 2) formulated the concept ofgenetotrophic disease. A genetotrophic disease is one in which, because of his genetic nature, the afflicted person requires an augmented supply of one or more specific nutrients and in which fulfilling these needs prevents or at least ameliorates the disease.The genetotrophic hypothesis was in mind when G. S., a severely retarded child, was treated by the senior author. When first seen, the patient was 7 years old and in diapers, could not speak, and had an estimated IQ of25-30. At her instigation, his blood and tissues were analyzed in the laboratories of Mary B.Allen, a biochemist in Richmond, VA. With the cooperation of a physician, Allen devised a nutritional supplement and G. S. 's parents agreed to administer it. There were no noticeable results for several weeks, but after some constituents of the supplement were increased G. S. suddenly began to improve. In a few days he was talking a little; in a few weeks he was learning to read and write, and he began to act like a normal child. When G. S. was 9 years old he read and wrote on the elementary school level, was moderately advanced in arithmetic, and, according to his teacher, was mischievous and active. He rode a bicycle and a skate board, played ball, played a flute, and had an IQ ofabout 90.

“…No evidence emerged that this was beneficial. Few years later, Harrell et al 16 reported that supplementary vitamins and minerals and thyroid hormone improved intelligence quotient scores and normalized physical appearance in children with mental deficiency. Reportedly, three children with DS showed the best results.…”

Vitamin supplements and purported learning enhancement in mentally retarded children.

“…The eight-month study consisted of double-blind experimental and control groups for four months, after which all subjects were placed on active agents. The IQs of the children studied ranged from 17 to 70, the ages from 5 to 15 (2).…”

A re-evaluation of nutritional goals -not just deficiency counts

“…This implies that the functioning of the brain at a psychological level depends on nutrition (6). It has been suggested that nutrient supplementation is beneficial for various medical problems (50,(53)(54)(55)(56)(57)(58)(59)(60)(61)(62)(63)(64)(65)(66)(67). Yet the optimal levels of intake with respect to reproduction, mental functions etc.…”
