A cohort of children (n = 70) diagnosed at pre-school age with DLI was reevaluated in elementary school. Language, cognitive, and motor outcomes were assessed through the use of the Battelle Developmental Inventory (BDI). Languagewas further assessed through the use of the Vineland Adaptive Behavior Scale, Peabody Picture Vocabulary, and Expressive One Word Picture Vocabulary Tests. Performance below -1.5 SD of the normative mean on any test was considered to represent impairment. Forty-three children (mean age, 7.4 ±0.7 years) underwent reassessment at a mean of 3.8 ±0.7 years after initial preschool assessment. Mean scores for BDI motor domains (FM, 78.3 ±11.4; GM, 84.9 ±13.3) fell below normative values. Twenty-two children (52%) had motor impairment (FM, 17 of 42; GM, 15 of 42); 35 of 43 (81%) continued to have language impairment. BDI communication raw scores correlated most strongly with FM (ρ= 0.73, P <.001) and GM (ρ= 0.58, P =.003) raw scores but showed only moderate correlations with cognitive raw scores (ρ= 0.41, P =.05). Impaired motor function is an important comorbidity in DLI. Factors critical to motor performance may also contribute to language deficits in DLI.展开更多
文摘目的研究听觉词汇学习测验(auditory vocabulary learning test,AVLT)对轻度认知障碍(mild cognitive impairment,MCI)进展为痴呆的预测能力。方法对257例MCI患者进行纵向随访,然后根据临床结果将其分为痴呆进展组和非痴呆进展组。比较这些组的基线人口统计学信息和AVLT评分。构建受试者工作特征(receiver operating characteristic,ROC)曲线以评估AVLT评分对MCI转归的区分值。结果在6年后的随访中,有45例受试者进展为痴呆,归为痴呆进展组(MCI progression,MCIp),3例受试者恢复正常认知,209例受试者维持MCI,一同归为非痴呆进展组(MCI non-progression,MCInp)。在基线时,MCIp组的AVLT评分明显低于MCInp,差异有统计学意义(P<0.05)。ROC曲线分析显示,AVLT延迟回忆(delayed recall,AVLT-DR)在区分MCI患者进展为痴呆方面有最大的曲线下面积(largest area under the curve,AUC),是重要预测指标。结论AVLT,尤其是AVLT-DR评分较低能较好预测MCI进展为痴呆,但由于其特异度偏低,需要联合其他特异度高的量表综合使用来运用于临床工作。
