Researchers in Chile conducted cognitive screening, performance on a decision-making task, functional testing, and magnetic resonance imaging (MRI) results with 73 patients after mild to moderate COVID-19 infection and 27 COVID-naïve patients with infections from other pathogens. Two follow-up sessions were conducted 15 days apart.

In some cases, these longer-term problems occur even in patients with relatively mild COVID-19.

Others develop dysautonomia, which causes palpitations, pressure rises or falls, dizziness and gastric problems.
