What are the age-related reference values for autonomic nerve function tests in healthy subjects?
Autonomic nerve function indices such as E/I ratio, acceleration index, and brake index decrease with age, highlighting the need for age-adjusted reference values when evaluating autonomic neuropathy.
Bergström et al. (1986) conducted a cross-sectional in Healthy (n=56). Increasing age was evaluated on Autonomic nerve function indices (E/I ratio, acceleration index, brake index, and blood pressures). Increasing age was associated with a fall in the E/I ratio, acceleration index, and brake index during autonomic nerve function testing in healthy subjects.
