Clinical Dementia Rating Scale (CDR) and dementia risk in the Mild Cognitive Impairment patients** Skala Klinicznej Oceny Stopnia Otępienia (CDR) a ryzyko otępienia u osób z łagodnymi zaburzeniami poznawczymi

Summary Introduction. Mild Cognitive Impairment (MCI) is a syndrome defined as cognitive decline greater than expected for an individual's age and education level but that does not interfere notably with activities of daily life. The main criterion of MCI is memory impairment, and the most common method of diagnosis is Clinical Dementia Rating (CDR), scored in MCI as 0.5. Aim. We tried to estimate the utility of particular CDR's boxes scores in dementia risk estimation. Material and methods. Boxes of CDR (Memory, Orientation, Judgment & Problem Solving, Community Affairs, Home & Hobbies, Personal Care) baseline scores of 103 MCI persons (mean age 69.32; 80 females and 23 males) were analyzed in 2 groups: non demented - ND (n = 80; mean age 68.71; 56 females and 24 males), and demented - D (n = 23; mean age 71.82; 14 females and 9 males) after 3-year follow up. Results. Any significant difference weren't observed in Memory, Orientation and Judgment. The most differentiating were Community Affairs and Home & Hobbies, which were on favor in the non-demented group (p = 0.05). Conclusions. MCI subjects who later develop dementia differ from stable ones in functional domains of CDR at baseline evaluation. Analysis of particular CDR's boxes scores might be helpful in further patients' management.
