The lack of translation of these associations in clinical use could be due to the multifaceted effect of diseases other than dementia.AbstractPurposeActivated platelets have been suggested to play an important role in the pathogenesis of dementia. Recent studies have shown contradictory results concerning the relationship between blood platelet indices and cognitive performance.MethodsThis cross-sectional study evaluates the relationship between basic platelet indices and cognitive and functional performance of 754 men and women, aged 60–105 years old, admitted to the geriatric hospital unit. Assessment of global cognitive function and functional ability were performed using Mini-Mental State Examination, the seven-point Clock Drawing Test, the Katz Activities of Daily Living, the Lawton Instrumental Activities of Daily Living Scale and the Vulnerable Elders Survey Questionnaire. As platelet indices, platelet count, mean platelet volume, plateletcrit and platelet distribution width were measured.ResultsThere was no significant correlation between cognitive performance and platelet indices. Out of the functional dependence questionnaires, only the Katz Activities of Daily Living and the Vulnerable Elders Survey Questionnaire were weakly correlated with platelet count (r = − 0.080 and r = 0.096) and plateletcrit (r = − 0.075 and 0.082, respectively), but these associations diminished in sex-specific analyses.ConclusionsCognitive and functional status are not systematically related to platelet indices in multimorbid hospitalized older adults.","claims":[{"public_id":"cl_d45b1b8bf8d68a473e187cece4f35e60","status":"active","text":"Basic platelet indices measured in routine
