We know that COVID-19 can cause severe pneumonia, blood clotting and heart problems. Additionally, COVID-19 is linked to neurological and psychiatric problems. For example, the virus that causes COVID-19 (SARS-2-CoV) may affect the brain, causing symptoms such as delirium (confused thinking) especially in older adults and those with dementia. High rates of anxiety, depression, and post-traumatic stress disorder have also been reported in people who recover after being hospitalized for COVID-19. Some patients treated in the hospital for COVID-19 reported extreme fatigue and mental difficulties long after they leave the hospital. Many patients who do not require a hospital stay experience a wide variety of symptoms that last for months after infection. This is called “long COVID.” COVID-19 impacts the brain and nervous system in both the short and long term. Looking to the future, “long COVID” could likely cause an increase in illnesses with negative consequences for our health.
