The relationship between cognition and the non-cognitive clinical findings in Turkish patients with Parkinson's disease

The relationship between cognition and the non-cognitive clinical findings in Turkish patients with Parkinson's disease

The study intended to examine the relationship between cognition and the clinical features at the onset of Parkinson disease (PD) in Turkish patients. Fifty patients were included and their cognitive status was evaluated by using the Turkish version of the Montreal Cognitive Assessment (MoCA-TR) test. Clinical findings were obtained by using all of the subparts of the Unified Parkinson's Disease Rating Scale (UPDRS). Disease severity was measured using the Hoehn and Yahr staging scale, and the Schwab-England Activities of Daily Living scale was used to assess the patients' disability. Bivariate correlation analysis was conducted to examine the demographic factors, disease duration, presenting motor symptoms (tremor or bradykinesia) and laterality (right or left), and the unique contributions of the UPDRS subscores to cognitive dysfunction on the MoCATR. This study carried out among PD patients revealed that, 36% (18/50) had cognitive impairment (score of
