Persistent post-COVID-19 neuromuscular symptoms

Area of Science:

• Neurology
• Infectious Diseases
• Immunology

Background:

• Neuromuscular symptoms can persist after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
• These symptoms may include autonomic dysfunction, sensory issues, and muscle pain, even without acute complications like Guillain-Barré syndrome.
• These persistent symptoms are often associated with long COVID, significantly affecting patients' quality of life.

Purpose of the Study:

• To review the current understanding of persistent post-COVID-19 neuromuscular symptoms.
• To discuss the evaluation and management strategies for these challenging symptoms.
• To highlight potential underlying mechanisms, such as small-fiber neuropathy.

Main Methods:

• Literature review of studies on post-COVID-19 neuromuscular complications.
• Analysis of reported symptoms including autonomic, sensory, and muscle-related issues.
• Examination of potential etiological factors and diagnostic approaches.

Main Results:

• Small-fiber neuropathy is identified as a potential cause of autonomic dysfunction and paresthesia in some long COVID patients.
• Mechanisms for myalgia and fatigue in long COVID remain unclear and require further investigation.
• A range of neuromuscular symptoms can persist post-SARS-CoV-2 infection, necessitating specific management strategies.

Conclusions:

• Persistent neuromuscular symptoms are a significant concern in long COVID patients.
• Small-fiber neuropathy offers a potential explanation for certain autonomic symptoms.
• Further research is crucial to elucidate the pathophysiology of myalgia and fatigue and to optimize patient management.
