What is the potential link between long Covid and dementia?

A study suggests that individuals suffering from long Covid may have an increased risk of developing dementia, including Alzheimer's disease.

What did researchers find in patients with long Covid?

Researchers observed that patients with long Covid had a 10 percent larger choroid plexus, a critical brain barrier, which was associated with Alzheimer's biomarkers.

Could long Covid lead to cognitive decline?

The study's findings suggest that long Covid may cause inflammation damaging the choroid plexus, potentially leading to cognitive decline and a higher risk of Alzheimer's-like symptoms.

Long Covid may increase the risk of dementia, a new study suggests.
Researchers found larger choroid plexus in long Covid patients.
Larger choroid plexus linked to Alzheimer's biomarkers and cognitive decline.

Long Covid Linked to Dementia Risk, Study Finds

A new study indicates a potential link between long Covid and an increased risk of dementia. Researchers in New York City examined over 80 individuals, comparing those with long Covid to healthy individuals and those who had recovered from Covid-19.

The study found that long Covid patients exhibited a 10 percent larger choroid plexus (CP), a crucial brain barrier responsible for waste removal and immune support. This enlargement was associated with blood markers indicating Alzheimer's disease progression.

Participants with a larger CP also performed slightly worse on cognitive tests. These findings suggest that long Covid may trigger inflammation, damaging the CP and potentially leading to cognitive decline and a higher risk of Alzheimer's disease.
