Severity score

The Aberrant Behavior Checklist-Community (ABC-C) is a measure used to identify treatment efficacy among intellectually impaired individuals. ABC Subscale IV (Hyperactivity) has 16 items, each can be rated from 0 to 3, with 0 equal to not at all a problems, one the problem is the behavior but slight in degree, to the problem is moderately serious, 3 the problem is severe in degree. For this subscale, score can go from 0 - 48. The higher the score, the worse the hyperactivity. The comparison in this study was made between the blinded phases when patients received either egg yolk (treated, +cholesterol) or egg substitute (untreated, -cholesterol). Order was randomized.

This was a double-blind, placebo-controlled, cross-over design. The trial was composed of five 2-week phases. Two phases, phases 2 and 4, were double-blinded. During these phases, subjects were either on placebo (egg substitute with no cholesterol) or cholesterol supplementation (pasteurized egg yolk). During the interval phases, 1, 3 and 5, subjects were maintained on baseline therapy of 150 mg/kg/day of crystalline cholesterol suspended in Ora-Plus. Order of placebo versus cholesterol was random with 6 subjects receiving placebo first (in phase 2) and 4 subjects receiving cholesterol containing pasteurized egg yolk first. 13 subjects were enrolled, only 10 subjects completed the study.
