Abstract
<jats:p>Background. Non-dementia cognitive impairment in older age is associated not only with changes in cognitive functioning but also with specific features of psychosocial adaptation. The analysis of quality of life, subjective evaluation of memory, and characteristics of the family environment may clarify the role of microsocial factors in maintaining subjective well-being in older adults. Aim. To analyze the characteristics of psychological adaptation in older adults with non-dementia cognitive impairment (NDCI), represented by groups with subjective cognitive decline (SCD) and mild cognitive impairment (MCI), based on a comparative assessment of their quality of life and family environment. Methods. A cross-sectional observational study was conducted with participation of 108 older adults. Neuropsychological examination methods were used together with the WHO Quality of Life questionnaire (WHOQOL-BREF), the Family Environment Scale (FES), and visual analogue scales assessing memory and independence in everyday functioning. Results. No statistically significant differences in overall quality of life indicators were found between participants with SCD and MCI. Individuals with MCI demonstrated stronger family control and lower involvement in active leisure activities, whereas participants with SCD showed higher levels of everyday activity and greater concern about their memory despite the absence of objective impairments. Several associations between executive cognitive functions and quality of life indicators were identified. Conclusion. The findings expand the understanding of psychosocial adaptation in older adults at the stage of non-dementia cognitive impairment and emphasize the role of microsocial factors and family dynamics in maintaining subjective well-being.</jats:p>
