Abstract

Background/Aims: To evaluate the utility of the Addenbrooke's Cognitive Examination-Revised (ACE-R) as a screening tool for mild cognitive impairment in Parkinson's disease (PD-MCI). Methods: PD patients underwent comprehensive neuropsychological and neurological evaluations and ACE-R assessment. Results: The ACE-R was superior to the Mini-Mental State Exam (MMSE) in detecting PD-MCI, with a cutoff score of ≤93 offering a sensitivity of 61% and a specificity of 64%. The utility of the ACE-R in detecting PD-MCI is largely influenced by the fluency sub-domain score, and has optimal discriminability when utilized in patients with lower levels of education (≤12 years of formal schooling). Conclusion: The ACE-R must be used cautiously as a screening tool for PD-MCI, with results being most influenced by its fluency sub-domain score and patient education levels.
