THE KERDÓ INDEX AS AN INDICATOR OF NEUROCIRCULATORY ASTHENIA IN ADOLESCENTS
Abstract
The Kerdó index (IK) is a simple and informative indicator reflecting the functional state of the autonomic nervous system (ANS). It plays a critical role in assessing neurocirculatory asthenia (NCA), a functional cardiovascular disorder frequently observed in adolescents during periods of rapid physiological and hormonal change. This study aims to evaluate the diagnostic and prognostic value of the Kerdó index in identifying autonomic imbalance in adolescents with neurocirculatory asthenia. Results demonstrate that the Kerdó index provides a reliable quantitative measure of sympathetic–parasympathetic balance and correlates significantly with clinical manifestations such as tachycardia, hypotension, and increased fatigue.
