29th Napa Pain Conference Sessions

Neurological Consequences of COVID-19 & Post-Acute Sequelae of COVID (PASC)


Aug 20, 2022 8:45am ‐ Aug 20, 2022 9:30am


Description

Among evaluated patients with long COVID, prolonged, often disabling, small-fiber neuropathy after mild SARS-CoV-2 was most common, beginning within 1 month of COVID-19 onset. Various evidence suggested infection-triggered immune dysregulation as a common mechanism. - Nath, 2022

Symptoms of long COVID are reported to be on-and-off, cyclic or multiphasic. A meta-analysis of pain-related symptoms reported for patients with long-term PASC determined that every one month of follow-up corresponded to a 45% increase in prevalence in patients who developed neuralgia after acute COVID-19 infection.

Weakness, often accompanied by myalgia and arthralgia, is a musculoskeletal manifestation of SARS-CoV-2 infection.

Central and peripheral nerve systems are one of the most susceptible targets for SARS-CoV-2 virus (neurotropism).

As well, a prolonged period of mechanical ventilation in the ICU may cause what is called “post intensive care syndrome” or “ICU-acquired weakness”, manifesting as cognitive dysfunction, muscle atrophy, sensory disruption and joint-related pain.

Residual effects from SARS-CoV-2 virus include fatigue, dyspnea, chest pain, persistent loss of taste and/or smell, cognitive changes, arthralgias, and decreased quality of life.
