We are finally getting some information regarding the affects of Covid-19 on the brain.
The news is horrible.
How COVID-19 Affects the Brain
COVID-19 has resulted in more than 120 million cases and 2.6 million deaths to date. Respiratory and gastrointestinal symptoms are accompanied by short- and long-term neuropsychiatric symptoms (NPs) and long-term brain sequelae.
Some patients present with anosmia, cognitive and attention deficits (ie, brain fog), new-onset anxiety, depression, psychosis, seizures, and even suicidal behavior. These present before, during, and after respiratory symptoms and are unrelated to respiratory insufficiency, suggesting independent brain damage. Follow-ups conducted in Germany and the United Kingdom found post-COVID-19 NPs in 20% to 70% of patients, even in young adults, and lasting months after respiratory symptoms resolved, suggesting brain involvement persists.
Entering through angiotensin-converting enzyme receptors, SARS-CoV-2 can damage endothelial cells leading to inflammation, thrombi, and brain damage. Moreover, systemic inflammation leads to decreased monoamines and trophic factors and activation of microglia, resulting in increased glutamate and N-methyl-d-aspartate (NMDA) and excitotoxicity. These insults induce new-onset or re-exacerbation of preexisting NPs.
