Long Covid could trigger changes in the brain that are similar to Alzheimer’s, new study says
How long Covid could be linked to Alzheimer’s symptoms
- New research from NYU Langone Health suggests that long Covid symptoms, affecting approximately 20 million Americans, may resemble those seen in Alzheimer's disease.
- The study indicates that long-term immune reactions following a Covid infection can cause swelling that damages the choroid plexus, a critical brain barrier.
- Researchers found that long Covid patients had a 10 percent larger choroid plexus compared to those who fully recovered, indicating chronic neuroinflammation and neurodegeneration.
- A larger choroid plexus is considered an early warning sign of future Alzheimer’s-like cognitive decline and was linked to poorer performance on cognitive tests.
- Scientists are continuing to monitor patients to determine if these brain changes are reversible and can predict long-term cognitive issues.
