“…Early research indicated rather poor developmental outcomes for children with chronic kidney disease (CKD) during infancy, with the incidence of developmental delays estimated at 60% to 85% (Bale, Siegler, & Bray, 1980;Baluarte, Gruskin, Hiner, Foley, & Grover, 1977;Bird & Semmler, 1986;Bock et al, 1989;McGraw & Haka-Ikse, 1985;Polinsky, Kaiser, Stover, Frankenfield, & Baluarte, 1987;Rotundo et al, 1982;Warady, 2002). Neurodevelopmental delays in infants and preschool children with CKD were linked to a number of neurologically based conditions including microcephaly, seizures, mental retardation, reduced growth rates, impaired hemispheric maturation, and abnormal electrophysiological findings (Bock et al, 1989;Kari, Gonzalez, Ledermann, Shaw, & Rees, 2000;McGraw & Haka-Ikse, 1985;Polinsky et al, 1987;Rotundo et al, 1982;Van Dyck & Proesmans, 2001). In addition, early malnutrition, aluminum toxicity, hypertension, and anemia were also associated with developmental delay in patients with childhood CKD (Andreoli, Bergstein, & Sherrard, 1984;Conley, 1987;Lande, Kaczorowski, Auinger, Schwartz, & Weitzman, 2003;Marsh et al, 1991;National Kidney Foundation [NKF], 2001;Sedman, Miller, Warady, Lum, & Alfrey, 1984;Sedman, Wilkening, Warady, Lum, & Alfrey, 1984;Warady, 2002;Winick, 1969).…”
