Overview
Pathophysiology of the Complications in the Nervous System
Mechanism of targetting the Nervous System
Complications in the Central Nervous System
Headache
- Pathophysiology
- The exact pathogenesis of headache in COVID 19 patients is not fully understood.
- It is thought that headache is the result of:
- Cytokine release
- There is higher concentration on IL-6 and INF-gamma in patients infected with SARS/ CoV2.
- Cytokines can disrupt blood brain barrier and cause tissue injury and cerebral edema.
- Direct invasion
- Metabolic disturbances
- Inflammation
- Dehydration
- Hypoxia

Complications in the Peripheral Nervous system
Guillain-Barre syndrome
- Pathophysiology
Guillain–Barre syndrome causes immune-mediated damage to the peripheral nerves that usually follows gastrointestinal or respiratory illnesses. The polyneuropathy in Guillain–Barre syndrome is believed to be due to cross-immunity against epitopes of peripheral nerve components that it shares with the epitopes on the cell surface of bacteria that produces an antecedent infection [1]. Most common antecedent infections are Campylobacter jejuni ,Zika virus and influenza virus.
The mechanism of Guillain–Barre syndrome in patients infected with COVID-19 is not fully understood yet.
COVID-19 stimulates inflammatory cells and produces various inflammatory cytokines and as a result, it initiates immune-mediated processes[2][3].'Molecular mimicry' as a mechanism of autoimmune disorder plays an important role in formation of Guillain–Barre syndrome. It is not yet clear whether COVID-19 induces the production of antibodies against specific gangliosides that usually appear with certain forms of Guillain–Barre syndrome[3]. In the future further investigations should be conducted about the mechanism of GBS in patients with COVID-19 for better understanding.
