Abstract
Three months after gastric partitioning for morbid obesity, 2 patients developed an unusual and severe form of polyneuropathy that affected their sense of position maximally. This disorder produced severe ataxia of the upper extremities and trunk, and pseudochorea. One patient died and the autopsy showed an extensive demyelinating polyneuropathy. Neuronal cell bodies in the anterior horns and dorsal root ganglia showed extensive accumulations of lipofuscin and Schwann cells showed extensive accumulations of lipid. This neuronal and Schwann cell lipidosis appears to result from starvation of the obese and has never been reported in other forms of human starvation or nutritional deficiency.
