Attention and Abstraction parts had average mistake rate.Citation: Fengler S, Kessler J, Timmermann L, Zapf A, Elben S, Wojtecki L, et al. ![]() There was a minor portion of mistakes in Naming and Orientation Tasks. Ĭonclusion: PD patients in Kyrgyzstan had the most mistakes in the Language, Delayed Recall and Visiospatial/ Executive parts.

In Delayed Recall Task, patients made approximately the same number of mistakes (46,3% – 59,3%). In abstraction part watch-ruler category had more errors (in 37% cases).ġ4,8% patients were able to recall all 5 words, 20,4% – 4 words, 13,0% – 3, 5,6% – 2, 13,5% – 1, 31,5% – couldn’t remember any word.

Results: The mean age of patients was 68,69 (☗,3). All tests were performed by two MoCA-certified specialists using paper-based format. Method: 54 PD patients were screened for cognitive impairment during their visits to the movement disorder clinic in Bishkek, Kyrgyzstan, during the 2020–2022 period. ![]() There were no studies conducted on MoCA common mistakes among PD patients in Central Asia before. The Montreal Cognitive Assessment (MoCA) is one of the routinely used instruments for indication of PD dementia and mild cognitive impairment. Objective: The aim of the study is to identify common mistakes in MoCA in patients with Parkinson’s disease (PD) in Kyrgyzstan.īackground: Cognitive impairment is a common non-motor symptom of PD that affects patients’ lives. ![]() Category: Parkinson's Disease: Cognitive functions
