Overview
Polyneuritis cranialis literally means inflammation of the cranial nerves. It is a rare neurological disorder characterised by multiple cranial nerve palsies sparing the spinal cord.[1]
Historical Perspective
- In 1937 French physicians Guillain G. et al. first described a postinfectious syndrome affecting the cranial nerves, associated with albuminocytological dissociation. The syndrome did not involve the limbs unlike Guillain-Barré syndrome and was called 'polyneuritis cranialis'.[2]
- The first COVID-19 outbreak news was first published by WHO on 5th January 2020.[3]
- Since mid-January 2020, right after the start of SARS-CoV2 outbreak neurological symptoms including the peripheral nervous system (PNS) symptoms have been reported in China (the first epicenter of the pandemic).[4]
- [WHO]] declared the COVID-19 outbreak a pandemic on March 12, 2020.
- Polyneuritis cralialis associated with COVID-19 was first reported in two patients by Consuelo Gutiérrez-Ortiz et al. from Madrid, Spain on April 17th, 2020. The team reported both Miller Fisher syndrome and polyneuritis cranialis in pattients with confirmed oropharyngeal RT PCR COVID-19 test.[5]

Differentiating COVID-19-associated polyneuritis cranialis from other Diseases

- COVID-19 associated Guillain-Barré syndrome is characterized by loss of deep tendon reflexes. Sensory and dysautonomic symptoms are also present.[6]
- Abnormal gait due to acute ataxic neuropathy is present in Miller Fisher type of GBS.[2]
- COVID-19 associated stroke:

Treatment
Medical Therapy
- The mainstay of therapy for COVID-19-associated polyneuritis cranialis is intravenous administration of immunoglobulin 0.4 g/kg for 5 days. It can be started after the neurological symptoms develop.
- COVID-19 medical therapy is as important as treating the associated polyneuritis cranialis.
- A few patients with COVID-19-associated polyneuritis cranialis may require physical therapy for residual muscle weakness.
Surgery
Surgical intervention is not recommended for the management of COVID-19-associated polyneuritis cranialis.
Primary Prevention
- The disease itself is associated with COVID-19 infection as believed to be an immune response so prevention of the infection itself is the most promising primary prevention strategy at the moment.
- There have been rigorous efforts in order to develop a vaccine for novel coronavirus and several vaccines are in the later phases of trials.[7]
- The only prevention for COVID-19 associated abdominal pain is the prevention and early diagnosis of the coronavirus-19 infection itself. According to the CDC, the measures include:[8]
- Frequent handwashing with soap and water for at least 20 seconds or using a alcohol based hand sanitizer with at least 60% alcohol.
- Staying at least 6 feet (about 2 arms’ length) from other people who do not live with you.
- Covering your mouth and nose with a cloth face cover when around others and covering sneezes and coughs.
- Cleaning and disinfecting.
