Study on Color Words Pick-Out Test (CWPT) Available for Classifying the Slight Disorder on the Preclinical Stage of Dementia

September 8, 2021 Medicine and Medical 0

Our investigation began to discover small decreases in the brain before the idea of mild cognitive impairment (MCI) and preclinical stage of dementia (PCSD). The goal of this study is to figure out what makes the CWPT (Color Word Pick-up Test) so good in detecting minor disorders and classifying them at the MCI and PCSD levels.

Methods: CWPT is a Stroop effect application that includes an examination of episodic memory to obtain evidence, 1 activation of the prefrontal lobe using inferred spectroscopy, 2 criterion-related validity using CWPT, WCST, HCL, FAB, and MMSE, and 3 criterion-related validity using CWPT, WCST, HCL, FAB, and MMSE. The sensitivity and specificity of three tests employing MMSE and CWPT are investigated.

1st Place: In comparison to quick repetition of 4-5 numbers in order, in reverse order, Kawashima arithmetic drill, and KPT, near infrared spectroscopy revealed that CWPT is the most effective test for brain activity (Kana Pick-out Test). 2 Only CWPT and WCST show normal distributions among the histograms obtained from 22 healthy ageing adults, and CWPT has a high connection with WCST. ③ For 29 dementia patients, sensitivity and specificity were assessed using the MMSE as a genuine condition and the CWPT as a predicted condition. By using the average-1.5SD of CWPT as a cutoff, sensitivity becomes 0.963 and specificity becomes 1.0.

Conclusion: These findings imply that the CWPT can be used to classify the degree of dysfunction during MCI and the preclinical stage of dementia.
