The virus’s interaction with the nervous system, including potential neurotropism, could also be a factor. Finally, the medications used to treat COVID-19 could have unintended consequences on pre-existing TD or contribute to its development.
Potential Role of Inflammation and Immune Response
Inflammation is a key component of the body’s response to infection, and COVID-19 is known to trigger a robust inflammatory cascade. This inflammatory response can extend beyond the lungs and affect various organs, including the brain. The brain’s intricate network of neurons and glial cells are vulnerable to inflammation-induced damage. This disruption could potentially exacerbate pre-existing TD or contribute to the development of new symptoms.
Cytokine storms, a severe overreaction of the immune system, are known to cause widespread damage throughout the body, and the brain is not immune to these effects. The specific mechanisms linking inflammation to TD require further investigation.
Potential Role of Viral Neurotropism
Some viruses have a tropism for specific tissues or cells within the nervous system. This property, called neurotropism, allows the virus to infect and replicate within the brain and other parts of the nervous system. If SARS-CoV-2 exhibits neurotropism, it could directly damage neurons or alter their function, contributing to the development or worsening of TD symptoms. Evidence of viral presence in the central nervous system during COVID-19 infection adds credence to this potential mechanism.
The precise role of neurotropism in TD development remains a subject of ongoing research.
Impact of COVID-19 Medications
Several medications are used to treat COVID-19, including antiviral agents and corticosteroids. These medications can have potential side effects, including movement disorders, potentially exacerbating or triggering TD symptoms in individuals predisposed to the condition. The risk-benefit assessment of these medications needs careful consideration in patients with a history of TD or those at risk.
Potential Pathways Linking COVID-19 to TD Development
