Lyme Carditis and Complete Heart Block in a 26-Year-Old Man Complete heart block from Lyme disease can deteriorate rapidly even after antibiotics begin. A 26-year-old man progressed from 2:1 AV block to complete block with asystole within 24 hours of starting treatment, requiring emergency pacemaker placement. His complete recovery and pacemaker removal after 19 days […]

Atypical Early Disseminated Lyme Disease Symptoms Early disseminated Lyme disease symptoms may present without the classic rash, making diagnosis more challenging. “On presentation to our hospital, the patient continued to complain of severe headaches and was noted to have mild unilateral right-sided facial droop and a diffuse macular rash throughout the body,” explains Kantamaneni in

Lyme Disease Risk in Dogs in Canada Lyme disease dogs Canada risk varies by region, with higher seroprevalence reported in areas closer to the United States. The highest seroprevalence of B. burgdorferi in dogs was observed in Nova Scotia (15.7%) and Eastern Ontario (5.1%), with surrounding areas showing moderate to low rates, according to Herrin

Could Dormancy Allow Lyme Disease to Survive Antibiotics? Lyme disease dormancy antibiotics research suggests that some forms of B. burgdorferi may survive treatment by entering low-activity states. Feng and colleagues from Johns Hopkins University identified FDA-approved drug combinations that may be effective against B. burgdorferi persisters in vitro. Persistence may represent one form of bacterial

Could Lyme Disease Cause ADHD Symptoms in Children? Lyme disease ADHD symptoms children may mimic attention deficit disorder, making diagnosis challenging. After 37 years treating Lyme disease, I have seen children diagnosed with ADHD whose symptoms improved with antibiotic treatment.

Stroke as a Manifestation of Lyme Disease: A Missed Diagnosis in Younger Patients Stroke as a manifestation of Lyme disease is often overlooked—especially in younger patients without traditional vascular risk factors. In clinical practice, unexplained stroke in an otherwise healthy individual should raise concern for Lyme neuroborreliosis, where infection-driven inflammation can affect cerebral blood vessels.

Johns Hopkins Study Supports Early Identification of Lyme Disease Patients for Re-Treatment Early identification of Lyme disease patients for re-treatment remains a critical clinical challenge. Even after standard antibiotic therapy, a subset of patients continue to experience fatigue, pain, and cognitive symptoms—raising important questions about who may benefit from closer follow-up or additional treatment. In

Pain and Fatigue After Lyme Disease Treatment: 3-Week Antibiotic Study Findings Some Lyme disease patients continue to experience significant symptoms even after completing standard treatment. Pain, fatigue, and depression may persist for months, affecting daily functioning and recovery. The cut-offs for fatigue and pain were chosen to reflect clinically significant levels based on the literature.

When Lyme Disease Causes a Positive Test for Mononucleosis Quick Answer: Lyme disease can cause false positive mononucleosis tests, especially Epstein-Barr virus (EBV) VCA IgM results. This cross-reactivity can delay Lyme diagnosis when fatigue, fever, and rash are mistaken for mono. In an article published in the journal Clinical Infectious Diseases, Pavletic from the National
