Lack of a correlation between demyelinating plaques on MRI scan and clinical recovery in multiple sclerosis by treatment with electromagnetic fields.

A 50 year-old woman presented in January of 1995 with a prolonged history of symptoms of multiple sclerosis (MS) and was classified at the time with a remitting-progressive course. Her chief symptoms included slurring of speech, impairment of vision with intermittent diplopia, difficulties with gait and balance with spastic-ataxic gait, mental depression, insomnia, fatigue, impaired cognitive functions notably poor short term memory and recurrent urinary tract and sinus infections. An MRI scan showed multiple nodular demyelinating lesions scattered in the subcortical white matter and periventricularly of both cerebral hemispheres. Over the following 18 months, while receiving three treatment sessions per week with picotesla electro-magnetic fields (EMFs) which were applied extracranially, she showed a significant recovery in both physical and mental symptoms and additionally experienced decreased susceptibility to infections. In addition, the course of her disease appeared to have stabilized as opposed to the preceding 5 years during which time she experienced insidious, steady deterioration in her functioning. Despite this remarkable clinical recovery through the application of EMFs, and MRI scan obtained at the same diagnostic center 18 months after initiation of treatment with EMFs showed no changes in the number and size of the demyelinating plaques. These findings demonstrate lack of a correlation between recovery of symptoms and the number and extent of demyelinating plaques on MRI scan. It has been known since the days of Charcot in the latter half of the 19th century that in MS there is a great disparity between the histopathological changes of the disease and neurologic deficits. This report enhances the notion that demyelination may reflect an epiphenomenon of the disease.
