The Frontiers paper is a single case report that admits that the woman's Lyme ELISA (and hence total antibodies to Lyme) was negative when she started experiencing dementia. Without antibodies against Lyme, it would be a mistake to claim that she had "chronic Lyme" (which isn't real regardless.) The paper is consistent with someone who had lyme disease (a not-uncommon illness) and then years later was diagnosed with dementia, but you can't say Lyme caused the dementia.
There is a scientific consensus against chronic Lyme based on decades of research.
It's disturbing that chronic Lyme has become a dangerous social phenomenon based on conspiracy theories, fake diagnoses, and fake treatments.
