Immediate recovery of cognitive functions and resolution of fatigue by treatment with weak electromagnetic fields in a patient with multiple sclerosis.
Cognitive deficits are common among patients with multiple sclerosis (MS). The pathogenetic mechanisms underlying the cognitive impairment in MS are unknown and there is presently no effective therapeutic modality which has shown efficacy in improving cognitive deficits in MS. A 53 year old college professor with a long history of secondary progressive MS experienced, over the preceding year, noticeable deterioration in cognitive functions with difficulties in short and long term memory, word finding in spontaneous speech, attention and concentration span. Unable to pursue his academic activities, he was considering early retirement. Mental examination disclosed features of subcortical and cortical dementia involving frontal lobe, left hemispheric and right hemispheric dysfunction. Almost immediately following the extracerebral application of AC pulsed electromagnetic fields (EMFs) of 7.5 picotesla intensity and a 4-Hz sinusoidal wave, the patient experienced a heightend sense of well being, which he defined as enhancement of cognitive functions with a feeling "like a cloud lifted off my head." He reported heightend clarity of thinking and during the application of EMFs he felt that words were formed faster and he experienced no difficulty finding the appropriate words. His speech was stronger and well modulated and he felt "energized" with resolution of his fatigue. There was improvement in manual dexterity and handwriting and testing of constructional praxis demonstrated improvement in visuospatial, visuoperceptive and visuomotor functions. It is suggested that some of the cognitive deficits associated with MS, which are caused by synaptic disruption of neurotransmitter functions, may be reversed through pulsed applications of picotesla range EMFs.
