Objective: To study alcohol related attention damage and factors having influence on it. Method: 39 inpatients with alcohol dependence were examined with Continuously Performance Test (CPT) before and after 6 weeks treatment. 45 normal staffs were collected as control. Results: The index of CPT in patient group at baseline was higher than that of normal control. After 6 weeks treatment, the above index declined but was still higher than control. The CPT results before treatment were related to plasma level of alcohol when admitted, age and history of alcohol use. Conclusion: Alcohol dose damage to the attention of patients in dependence.

Objective To explore the effect of application of continue performance test (CPT) in screening of attention deficit hyperactivity disorder( ADHD ). Methods Thirty-five children with ADHD and65 normal children had been applied with CPT and Conner questionnaire test. Used rank sum test to examine the outcome, established receiver operating characteristic (ROC) curve, analyzed the most valuable index among various data, formulated abnormal critical value, and carried on a consistency check between CPT screening outcome and clinical diagnosis outcome. Results Each CPT index of 35 children with ADHD was obviously higher than those of normal children(P＜ 0.05 ). Most indexes' area under the ROC curve exceeded 0.7, reactive time of VST was the highest among each index which achieved 0.915. It was high conformity between CPT screening outcome and clinical diagnosis outcome (Kappa = 0.935 ). Conclusion CPT can be applied in ADHD screening.
