Summary
COVID-19 survivors may experience prolonged autonomic dysfunction, affecting recovery. This study found higher pupillomotor, urinary, and sudomotor symptoms in patients post-COVID-19, highlighting the need for further investigation into long-term effects.
Area of Science:
- Neurology
- Infectious Diseases
- Physiology
Background:
- Autonomic dysfunction is a known complication of viral infections.
- Investigating post-viral syndromes is crucial for understanding long-term health impacts.
Purpose of the Study:
- To evaluate autonomic functions in patients who have recovered from coronavirus infectious disease 2019 (COVID-19).
Main Methods:
- A cross-sectional study comparing 112 COVID-19 survivors with 106 healthy controls.
- Autonomic symptom assessment using the SCOPA-AUT scale.
Main Results:
- COVID-19 patients showed significantly higher pupillomotor, urinary, and sudomotor dysfunction.
- Fatigue during acute COVID-19 correlated with higher overall autonomic dysfunction.
- Smell loss and dyspnea were risk factors for pupillomotor dysfunction post-COVID-19.
Conclusions:
- Prolonged autonomic dysfunction is suggested in many COVID-19 survivors.
- These persistent symptoms may impede clinical recovery after COVID-19.

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.

The autonomic nervous system (ANS) is a critical component of the peripheral nervous system, primarily responsible for regulating involuntary bodily functions and maintaining homeostasis. It functions in tandem with the central nervous system (CNS) to seamlessly coordinate various physiological processes without the need for conscious control.
The ANS comprises two main divisions: the sympathetic and parasympathetic divisions. These divisions function antagonistically to maintain a dynamic...

Ganglionic blockers inhibit autonomic activity by blocking nicotinic receptors in the autonomic ganglia, suppressing impulse transmission. These blockers lack selectivity between sympathetic and parasympathetic ganglia and are ineffective as neuromuscular junction antagonists. They can be categorized into two groups:

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

01:26Autonomic Nervous System: Overview
6.0K
The human nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord, while the PNS contains nerve cells, clusters of nerve cells, and the sensory receptors that are outside the CNS. The PNS has two types of nerve cells: sensory (afferent) and motor (efferent). Sensory cells send signals to the CNS from receptors, and motor cells carry signals from the CNS to organs, muscles, and...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
