Resolution of partial cataplexy in multiple sclerosis by treatment with weak electromagnetic fields.
Cataplexy, an ancillary symptom of narcolepsy, involves the sudden loss of muscle tone without altered consciousness usually brought on by sudden excitement or emotional influence and extreme exertions (Guilleminault et al., 1974; Parks et al., 1974; Guilleminault, 1976; Aldrich, 1992; 1993; Scrima, 1981; Baker, 1985). Attacks of generalized cataplexy produce complete atonic, areflexic partial or complete paralysis of striated muscles commonly involving the leg muscles resulting in collapse of the knees and falling while milder forms often termed partial cataplexy may manifest by sagging of the face, eyelid, or jaw, dysarthria, blurred vision, drooping of the head, weakness of an arm or leg, buckling at the knees, or simply a momentary sensation of weakness that is imperceptible to observers (Guilleminault, 1976; Aldrich, 1993). The duration of cataplexy is usually a few seconds, although severe episodes can last several minutes and rarely several hours or days in the case of "status cataplecticus" (Parkes et al., 1974; Guilleminault, 1976; Billiard & Cadilhac, 1985; Aldrich, 1992; 1993). This report concerns a 51 year old man with chronic progressive multiple sclerosis who exhibited daily episodes of partial cataplexy which resolved within 3 weeks after he received treatment with picotesla electromagnetic fields.
