Email Address "If we accelerate our emphasis on trying to use neuroscience in a more principled way, it will pay dividends for these ICU patients, whether they are being treated for COVID-19 or otherwise. "We can likely mitigate this dysfunction by using the EEG to monitor brain state and guide anesthetic dosing," says Dr. Brown. feelings of heaviness or sluggishness. All patients had a flaccid paralysis after awakening that remained present for the recorded days in the ICU or resolved only very slowly. It is important to take into account the possible reversibility of prolonged unconsciousness in patients with COVID-19 admitted to the ICU, which warrants watchful waiting in such cases. Anesthesia-induced delirium has been highly prominent in medical literature over the past decade and is associated with ventilation. Though most patients' symptoms slowly improve with time, speaking with your healthcare provider about the symptoms you are experiencing post-COVID could help identify new medical conditions.

"The body mounts an enormous inflammatory response, and it turns out to be pathologic as inflammation starts to damage tissues across all organ systems.
