Neuro-COVID-19

Area of Science:

• Neurology
• Infectious Diseases
• Immunology

Background:

• Neuromuscular manifestations are frequent in COVID-19, including dizziness, headache, myopathy, and sensory disturbances.
• Acute central nervous system disorders in COVID-19 patients, such as delirium and stroke, are associated with high mortality.
• Encephalitis/encephalopathy in COVID-19 can result from direct viral infection, systemic hypercytokinemia, or autoimmune responses.

Purpose of the Study:

• To summarize the neuromuscular manifestations of COVID-19 and its sequelae.
• To discuss the classification and mechanisms of COVID-19-associated encephalitis/encephalopathy.
• To highlight the need for diagnostic criteria and treatments for long COVID neuromuscular symptoms.

Main Methods:

• Review of current literature on COVID-19 neurological and neuromuscular complications.
• Analysis of reported cases of encephalitis/encephalopathy and post-acute COVID-19 syndrome.
• Examination of adverse reactions to COVID-19 vaccines related to neurological conditions.

Main Results:

• Common neuromuscular symptoms include dizziness, headache, myopathy, olfactory/gustatory issues, anxiety, depression, sleep disturbance, muscle weakness, brain fog, and cognitive impairment.
• COVID-19 encephalitis/encephalopathy has three main causes: direct SARS-CoV-2 infection, cytokine storm-induced damage, and autoimmune encephalitis.
• Rare neurological adverse events post-vaccination include vaccine-induced thrombotic thrombocytopenia, Guillain-Barré syndrome, and facial paralysis.

Conclusions:

• Neuromuscular and neurological complications are significant aspects of COVID-19 and long COVID.
• Understanding the diverse mechanisms behind these conditions is crucial for effective management.
• Further research is needed to establish clear diagnostic and therapeutic guidelines.
