The risk of blood clots in those with long-haul COVID-19 may be associated with damage from severe inflammation, although scientists don’t know how long the inflammation can persist. Specifically, heart damage caused by COVID-19 is likely the result of clots in the small vessels, or capillaries, in the heart. The coronavirus that causes COVID-19 can make blood cells more likely to coagulate, or clump and form clots. Damage to the hippocampus may put people with COVID-19 long-haul symptoms at risk for the hippocampal-related degeneration characteristic of Alzheimer’s disease.ĭoro Guzenda // Shutterstock More frequent blood clots These cognitive difficulties may be the result of damage to the hippocampus, the part of the brain that plays an important role in learning and memory.

Dyspnea has been linked to viral damage of the alveolar and epithelial cells in the lungs, and inflammatory damage to vascular cells.
