This paper examines the theoretical and clinical features of early diagnosis of affective disorders in dementia. Recent research demonstrates that depression, anxiety disorders, apathy, and emotional lability may serve as early markers of dementia and often appear long before pronounced cognitive decline. Underestimation of these symptoms leads to delayed diagnosis, reduced treatment effectiveness, and deterioration in the quality of life of patients and their families. The article analyzes clinical, neuropsychological, and biomedical approaches to identifying affective disturbances, including psychometric assessment scales, neuroimaging, biomarkers, and modern digital technologies. Special attention is given to the prospects of applying machine learning algorithms for early prediction of neurodegenerative conditions. The findings confirm the crucial role of timely diagnosis of affective disorders in improving dementia outcomes and optimizing clinical practice.
