We’ve learned a lot about COVID’s effects on the brain over the past two years. And frankly, it’s not pretty. Brain fog, “long COVID”, sudden death, all resulting from neurological damage done by this awful virus. Despite quarantines, masks and vaccines, we’re still in the middle of the pandemic, and it’s still unclear if the end is in sight - or if it will ever end. But knowledge is power. So let me tell you about everything we’ve learned about what this coronavirus does to your brain. We’ll take a deep dive into the various issues that have come up, and get a better understanding of the short and long term impacts of SARS-CoV-2 on our cognition and mental health.
