'Long COVID" can cause Vascular issues. [View all]
As I remember it Trump had a pretty severe case back in 2020 when he was treated for it.
Here is an NIH paper about this:

Abstract
SARS-CoV-2, the causative agent of the ongoing COVID-19 pandemic, has revealed a broader impact beyond the respiratory system, predominantly affecting the vascular system with various adverse manifestations. The infection induces endothelial dysfunction and immune system dysregulation, creating an inflammatory and hypercoagulable state. It affects both microvasculature and macrovasculature, leading to thromboembolic events, cardiovascular manifestations, impaired arterial stiffness, cerebrovascular complications, and nephropathy, as well as retinopathyfrequently observed in cases of severe illness. Evidence suggests that SARS-CoV-2 infection may result in persistent effects on the vascular system, identified as long-term COVID-19. This is characterized by prolonged inflammation, endotheliopathy, and an increased risk of vascular complications.
Another thought is reduced bloodflow to the brain can cause mental impairment.
Note I posted this as a reply on another thread, but have not heard this as a theory elsewhere so making it a separate post.
It would be a sort of poetic justice if true.
