Up to 20% of COVID-19 patients who enter the intensive care unit (ICU) with neurological issues or deficits have a higher mortality risk. Even after recovering and leaving the ICU, patients may develop long-term neurological conditions such as depression, obsessive compulsive disorder, psychosis, Parkinson’s disease, and Alzheimer’s disease. ICU patients who take numerous medications or have pre-existing medical conditions can develop memory loss, slow processing speed, delirium, or even coma. Patients with multiple sclerosis, amyotrophic lateral sclerosis, and respiratory dysfunction may struggle to survive ICU hospitalization, and those on immunosuppressive medications may decline faster.
