Depressive Disorders, Cognitive and Physical Function of Older People in Early Dementia Detection

Abstract

Background: Aging is associated with cognitive decline, leading to cognitive and physical impairments, which are risk factors for loss of independence and dementia development. Early diagnosis is beneficial for both, the patient and their family, to avoid long-term consequences. The aim of this study was to analyze the frequency of depressive disorders and their influence on cognitive and physical function of older people in early dementia detection. Methods: There were 852 patients, aged at least 60 years, from the Central Teaching Hospital. The study was conducted between September 2022 and June 2023. The qualified participants were examined using four tools: Geriatric Depression Scale (GDS), Instrumental Activities of Daily Living (IADL), Timed Up and Go (TUG) and Schulman’s Clock-Drawing Test. Results: Over one-third had depressive disorders. A relationship with p < 0.05 was observed between GDS and IADL: r = −0.61. A relationship with p > 0.05 was observed between GDS and TUG: r = −024. A relationship with p < 0.05 was observed between GDS and CDT: r = 0.74. Conclusions: The first signs of depressive disorders in older people may be considered an indication for further diagnosis of dementia.
