My sister-in-law got the vaccine in March. This week she went to the ER for dementia spells. My brother said she's had about 10 episodes since Thursday where she is unable to answer even the simplest questions. It's almost as if she is catatonic. It's not continuous but has occurred enough to go to the hospital. They did all sorts of tests and found nothing. I suggested he record it so the doctors can actually see what happens during an episode. They are going to her doctor tomorrow. She is only 58 and I am very worried about her. He refused to be vaccinated and can't even mention the vaccine without a fight. She will never admit it was the vaccine.
I think it was the Johnson and Johnson but not sure.
All covid vaxes are mRNA.
