Objective: Cancellation test is easy and feasible to performance in cognitive evaluation, which is usually used to assess attention ability in children. We explored the feasibility of cancellation test in adult cognitive evaluation. Methods: Adult subjects with complaint of memory decline in the department of Neurology,Tsinghua Yuquan Hospital were enrolled and examined with cancellation test,clinical dementia rating (CDR), mini mental state examination (MMSE) and Montreal cognitive assessment (MoCA) at the same time from January 2014 to December 2018. The subjects were slipped into normal cognition, cognitive mild impairment, dementia (including mild dementia, moderate dementia and serious dementia) groups according to their CDR score. Results: Cancellation index was presented as the results of cancellation test. Cancellation index was significant higher than it was in cognitive impairment group (P<0.05). However, there was no significant difference among mild/moderate/serious dementia groups (P>0.05). Cancellation index was moderately correlated with the scores of MMSE, MoCA and CDR (P<0.05). According to ROC curve,the sensitivity and specify of cancellationtest was 85.3% and 45.3%,respectively with attention index as 0.3856. Conclusion: Cancellationtest is easy and feasibility to detect cognitive impairment sensibility, which can be used for early screening of cognitive function.
