Research suggests immune response may be cause of delirium and brain fog in Covid patients
Severe Covid infections can cause immune reactions that damage nerve cells in the brain, causing memory problems and confusion, and potentially raising the risk of long-term health issues, research suggests.
Scientists at King’s College London found that a wayward immune response to the virus increased the death rate of neurons and had a “profound” impact on regeneration in the hippocampus region of the brain, which is crucial for learning and memory.
