OBJECTIVE: Some studies about the @entity717 Society checklist for the diagnosis of @entity191 ( @entity191 ) @entity303 ( @entity3602 ) suggested that its accuracy was not totally satisfactory. Our study focused to evaluate the two items of the checklist related to the cognitive assessment. METHODS: We assessed 95 consecutive @entity1 with a diagnosis of @entity191 using the UPDRS, Hoehn and Yahr, Schwab and England scales, Pfeffer Functional Activities Questionnaire, MMSE, Clinical @entity303 Rating, clock drawing test, verbal fluency test (animals), digit span, word list battery of CERAD, Frontal Assessment Battery and the 15-item Geriatric Depression Scale The cognitive diagnosis was based on the MDS diagnostic criteria for @entity3602 . The checklist was completed later by a blinded investigator. The data were evaluated using descriptive analysis and calculation of sensitivity, and specificity of the checklist for the diagnosis of @entity3602 . RESULTS: 33 @entity1 (35%) were diagnosed with @entity3602 . The ROC curve showed that the MMSE cut-off score < 26 had the highest accuracy (sensitivity: 94%, specificity: 55%) for the diagnosis of @entity3602 . Using the checklist with original cut-off scores we found sensitivity of 97% and specificity of 58%. Using an alternative way to interpret the cognitive assessment of the checklist we found sensitivity of 94% and specificity of 89% for the diagnosis of @entity3602 . CONCLUSIONS: Our findings suggest that to improve the accuracy of the checklist, it would be necessary to adjust the way we use and interpret the cut-off scores of the MMSE and of the subtests, without the need to eliminate their use.
