Research by Dr. Alan MacDonald suggests that Lyme disease bacteria, Borrelia burgdorferi, reside within parasitic nematodes in the brains of patients with neurological conditions like MS, glioblastoma, and Lewy body dementia. His findings, presented on Capitol Hill, indicate that standard Lyme tests are inadequate, leading to misdiagnosis and potentially fatal consequences. This research builds upon prior studies showing nematodes in ticks, highlighting a potential link between tick-borne infections and chronic brain diseases. MacDonald utilized FISH technology to confirm the presence of Borrelia DNA within the nematodes. The study emphasizes the need for improved diagnostic tools and treatment strategies for Lyme disease.
