title: Cerebral dysfunction following infantile dietary chloride deficiency.
abstract: Twenty-two children who were chloride-depleted in infancy due to a chloride-deficient diet and who had resultant hypochloremic alkalosis were analyzed in regard to their signs and symptoms, metabolic studies, and growth parameters. Deceleration of weight, linear growth, and head growth occurred in most, and persistent growth failure occurred in some. The majority had cognitive deficits at follow-up. Comparison with growth parameters in a chronically malnourished group of children who had a variety of disorders revealed a similar degree of deceleration of weight (p = 0.50) and height (p = 0.70), but more severe deceleration of head growth (p = 0.01). Comparison with follow-up cognitive deficits reported in the United States medical literature in children with similar severity of nutritional deprivation indicates that the chloride-depleted infants had more frequent and more severe cognitive deficits (p = 0.09). Cognitive deficits have been documented in U. S. children who are nutritionally deprived only when disorders causing concomitant chloride depletion are responsible for the malnutrition.
