Abstract
Cognitive impairments are one of the leading problems of neurology and psychiatry due to their wide prevalence, especially in the elderly and senile age, the difficulty in diagnosis and treatment. In addition, the increase in life expectancy of the population in Russia and in the world will undoubtedly cause a rapid increase in patients with dementia and other cognitive impairments. However, dementia in most cases does not develop overnight; its development is preceded by a long period of time when the existing cognitive impairments do not yet disrupt the patient's household and professional activity. Cognitive impairment of this degree is called "pre-dementia" and is divided into subjective cognitive decline, subtle and mild cognitive impairments. This article discusses the key problems of subjective cognitive decline and subtle cognitive impairment, the interpretation and diagnosis of which raises the most frequent questions among clinicians. So, based on a review of Russian and foreign literature, the authors substantiate how it is possible to distinguish between subjective cognitive decline and subtle cognitive impairment, and discuss where the line with moderate cognitive impairment is. Separately, diagnostic algorithms and treatment tactics for subjective cognitive decline and subtle cognitive impairment are presented.
