People who are very sick with COVID-19, including those who have to be put on respirators, can have mood issues, namely depression, and cognitive slowing. The effects of COVID-19 on mental health and cognitive function in people with only mild symptoms are less known. As with other long-term effects, people will experience a spectrum of symptoms over a course of time. Patients with COVID-19 often have stress, mood changes, or even depression associated with being ill with COVID-19. When in doubt, people should seek mental health support and resources.
