Due to demographic trends both in Russian Federation and worldwide, which indicate an increase in the number of elderly people, the early diagnosis of geriatric syndromes is becoming increasingly relevant. One such syndromes is frailty syndrome, for the diagnosis of which several approaches and more than 200 assess-ment scales have been developed. The most widely used questionnaire in Russia is “Age Is No Barrier,” which includes 7 questions about the functioning of various systems and organs and the assessment of a person’s overall well‑being. Based on the results of the questionnaire, the patient may be classified into one of the fol-lowing categories: “frail” (high risk of asthenia syndrome), “pre‑frail” (moderate risk of senile asthenia), and “robust” (low risk of frailty). Based on current literature data, official protocols, and the results of scientific studies published in online resources such as CyberLeninka, Sudact, PubMed, ResearchGate, and Springer Nature Link, an optimized version of the “Age Is No Barrier” questionnaire has been developed, which makes it possible to identify senile asthenia syndrome with greater accuracy and specificity.
