The BNI Screen for Higher Cerebral Functions (BNIS) was administered to 41 patients with known cerebral dysfunction. 22 psychiatric patients (some of whom were psychotic) without documented brain lesions, and 22 medical inpatients without neurological or psychiatric diagnoses. Patients with cerebral dysfunction scored significantly lower than the medical and psychiatric patients (p < 0.05). Utilizing the recommended cutoff score of 47, 40 of the 41 brain-dysfunctional patients were correctly classified as impaired, but only seven of the medical and five of the psychiatric patients were correctly classified. Using age-based T-scores, 36 of the 41 brain-dysfunctional patients (87.8%) were correctly classified. Specificity improved slightly, but these numbers were still low (55%), primarily because psychotic patients performed like neurological patients (100%). This study provides further empirical validation of this screening instrument in identifying patients with brain disorders.
对41名已知脑功能障碍的患者进行了BNI高级脑功能筛查（BNIS）。22名无脑部病变记录的精神科患者（其中一些患有精神病），以及22名无神经或精神疾病诊断的内科住院患者。脑功能障碍患者的得分显著低于内科和精神科患者（p < 0.05）。采用推荐的临界值47，41名脑功能障碍患者中有40名被正确分类为受损，但内科患者中只有7名、精神科患者中只有5名被正确分类。使用基于年龄的T分数，41名脑功能障碍患者中有36名（87.8%）被正确分类。特异性略有提高，但这些数字仍然较低（55%），主要是因为精神病患者的表现与神经科患者相似（100%）。本研究为该筛查工具在识别脑部疾病患者方面提供了进一步的实证验证。
