Reversal of a Visuoconstructional Disorder by Weak Electromagnetic Fields in a Child with Tourette's Syndrome

Abstract

Tourette's syndrome (TS). a chronic familial neuropsychiatric disorder of unknown etiology, is characterized clinically by the occurrence of motor and vocal tics and by the presence of a variety of neurobehavioral and neurocognitive abnormalities including hyperactivity, self-mutilatory behavior, obsessive-compulsive behavior, learning disabilities, and conduct disorder. Cognitive deficits related to right hemispheric dysfunction are common in TS patients accounting for decrements in visuospatial, visuoconstructional and visuomotor skills. An 11 year old boy with a 5 years history of TS exhibited during a routine neuropsychological assessment an unusual visuoconstructional disorder which previously has been observed in dyslexic children. Specifically, when instructed to draw a bicycle from memory, he drew spontaneously a design executed from the perspective of a bird's eye view. After receiving a 20 minute treatment session with picotesla range electromagnetic fields (EMFs) applied extracranially, this visuocontructional disorder was spontaneously reversed and he drew an elaborate and detailed bicycle positioned in profile. A placebo EMF treatment, which was administered prior to magnetic therapy, had no effect on this child's visuoconstructional disorder. During the ensuing week there was a marked reduction in the child's hyperactive behavior with attentuation of motor tics. Spontaneous drawing of a bicycle a week after the administration of magnetic therapy was executed in profile although some elements were presented from a bird's eye view. This case demonstrates the potential impact of treatment with picotesla EMFs in reversing specific cognitive deficits in TS related to right posterior hemispheric dysfunction.
