摘要: Evidence that the thyroid may play a role in pathogenesis of attention deficit hyperactivity disorder (ADHD) comes from observations 48% to 73% children with syndrome resistance hormone (RTH) have ADHD. Casual subjects RTH suggested treatment improve symptoms The aim this study was determine whether has beneficial effect on behavior RTH. A prospective, randomized, double-blinded, placebo-controlled, cross-over conducted evaluate rapid acting hormone, liothyronine (L-T3), 8 ADHD + RTH, and 9 normal function (ADHD Only). Parent teacher ratings (Conners scale) computerized continuous performance test (CPT) were used as objective measures hyperactivity, impulsivity. L-T3 had no Conners Hyperactivity Index 7 Only; it caused improvement deterioration 1 subject each. In contrast, rating 5 showed improvement, whereas 3 remained unchanged. associated increased commission errors Only decreased 4 ADHD, particularly those exhibit supraphysiological doses be reducing majority who do not or detrimental.
