Disorders of the Autonomic Nervous System

639
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.

Autoregulation of Blood Flow01:17

Autoregulation of Blood Flow

2.3K
Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation....

Summary

Cerebral microangiopathy is linked to autonomic nervous system dysfunction, particularly in older patients with leukoaraiosis and cognitive decline. Factors like blood pressure variability and heart rate variability significantly influence this association.

Area of Science:

  • Neurology
  • Cardiology
  • Internal Medicine

Background:

  • Cerebral microangiopathy (CM) is a common finding in neurological practice.
  • Autonomic nervous dysfunction (AND) can coexist with CM, but the relationship is not fully understood.

Purpose of the Study:

  • To investigate the correlation between cerebral microangiopathy and autonomic nervous dysfunction.
  • To identify influencing factors of CM in patients with concomitant autonomic dysfunction.

Main Methods:

  • 162 hospitalized CM patients were analyzed.
  • Patients were categorized based on Autonomic Symptom Profile (ASP) scores.
  • Pearson correlation and regression analyses were performed.

Main Results:

  • Significant differences between groups included age, leukoaraiosis, cognitive function, and various cardiovascular and autonomic markers.
  • Age, leukoaraiosis, cognitive function, blood uric acid, homocysteine, blood pressure variability (24-h, daytime, nighttime SBPSD), and heart rate variability (SDNN, RMSSD, HF, LF) were associated with CM and AND.
  • Hypertension, SDNN, RMSSD, HF, and LF showed negative correlations with ASP scores and SSR, while age, leukoaraiosis, cognitive function, blood uric acid, and Hcy showed positive correlations.

Conclusions:

  • Age, leukoaraiosis, cognitive function, blood uric acid, homocysteine, blood pressure variability, and heart rate variability are key factors associated with CM and AND.
  • These factors significantly influence the presence of autonomic dysfunction in CM patients.
