Disorders of the Autonomic Nervous System

833
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Summary

Concussed athletes show altered autonomic responses to cognitive tasks, measured by heart rate variability (HRV). A switch task revealed these changes, but they diminished when combined with motor activity, suggesting complex interactions in dual-task scenarios.

Area of Science:

  • Neuroscience
  • Sports Medicine
  • Autonomic Physiology

Background:

  • Dual tasks offer realistic athletic demands, revealing autonomic alterations in concussed athletes.
  • Previous research on single cognitive/motor tasks showed persistent autonomic changes post-concussion.
  • The autonomic response to dual tasks in concussed athletes remains understudied.

Purpose of the Study:

  • To evaluate autonomic responses in asymptomatic athletes with a history of concussion during a complex dual task.
  • To investigate how a cognitive switch task and a combined motor-cognitive dual task affect autonomic regulation.

Main Methods:

  • Heart rate variability (HRV) was measured in 34 athletes (16 concussed, 18 controls).
  • HRV was recorded during rest, a cognitive switch task, and a dual task (motor + cognitive).
  • Data were analyzed using 4x2 mixed-design ANOVAs to compare groups and conditions.

Main Results:

  • Concussed athletes showed a significant increase in HRV (SDNN) after the switch task compared to rest.
  • This parasympathetic response to the switch task was not observed when combined with a motor task.
  • The dual task, with or without prior aerobic exercise, abolished the switch task's effect on HRV in concussed athletes.

Conclusions:

  • Dual tasks may involve competing motor and cognitive mechanisms affecting autonomic responses.
  • The cognitive switch task is sensitive enough to detect autonomic alterations via HRV in concussed athletes.
  • HRV during specific tasks could be a clinical tool for assessing return-to-sport readiness.
