This review discusses chronic Lyme disease, a rare condition caused by ongoing infection with the bacteria that causes Lyme disease. The main symptoms include progressive brain and spinal cord inflammation, skin changes, nerve damage, and joint pain. The authors explain how doctors can diagnose chronic Lyme using specific blood tests and cerebrospinal fluid tests, and recommend standard antibiotic treatment rather than experimental or prolonged approaches.
This review is relevant to ME/CFS patients and researchers because it clarifies the distinction between chronic Lyme disease and post-Lyme disease syndrome—an important differential diagnosis—and emphasizes that chronic Lyme requires objective clinical findings rather than isolated subjective symptoms. Understanding these diagnostic boundaries helps prevent misattribution of ME/CFS symptoms to Lyme disease and ensures patients receive appropriate, evidence-based diagnostic workup and treatment.
This review does not establish whether Lyme disease causes ME/CFS, nor does it prove that patients with ME/CFS who test positive for Lyme antibodies have active chronic Lyme infection. The study also does not evaluate the effectiveness or safety of prolonged or combination antibiotic regimens, which it argues against based on guideline review rather than new experimental evidence.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
