Objective: To validate the three time-difference neuropsychological protocols developed by the National Institute of Health/National Institute of Neurological Disorders and Stroke (NINDS) and the Canadian Stroke Network for assessment of vascular cognitive impairment (VCI) in Mandarin-speaking subjects and to investigate the clinical application of the shortest form. Methods: Patients aged 50 years or older who had a stroke were invited to participate in the study. Clinical diagnosis of VCI was made. The NINDS-VCI Neuropsychology Protocols, 60-, 30-, and two 5-minute protocols, were administered. The criteria validities of the cognitive protocols against the diagnoses of stroke and VCI were determined via Receiver Operating Characteristic (ROC) analysis. The optimal cut-off point for the 5-minute protocols total score was estimated for clinical use in screening. Results: Eighty-three patients and 53 controls were recruited during the study period. Patients with stroke performed more poorly than the control group in the three neuropsychological protocols. Forty-two patients with stroke were diagnosed with VCI. VCI was used as the standard to estimate the criteria validities. The area under the ROC curve was 0.78, 0.80, 0.75, and 0.73 for the 60-, 30-, 5-mintue protocol-A and 5-minute protocol-B, respectively. Conclusion: These modified neuropsychological protocols can be used as valid instruments when performing comprehensive cognitive assessment or for screening of VCI in Taiwan.
