Treatment-resistant depression in teenagers rarely prompts Lyme disease testing—even when accompanied by cognitive decline, academic failure, and a history of tick exposure. Neuropsychiatric symptoms—including depression, anxiety, irritability, and cognitive impairment—are increasingly recognized manifestations of neurologic

Atypical Lyme Disease Symptoms That Complicate Diagnosis Atypical Lyme disease symptoms can make diagnosing the infection difficult.

Lyme Arthritis After Surgery: Five Reported Cases Lyme arthritis can develop after orthopedic surgery and may be mistaken for postoperative infection.

Tick Bites During Pregnancy: A Clinical Perspective Tick bites during pregnancy raise important concerns about Lyme disease and other tick-borne infections. Some authors recommend prophylaxis with a single 200 mg dose of doxycycline after a tick bite, suggesting the risk to the unborn baby is low. However, the evidence supporting this recommendation remains limited, and

Babesia in Dogs: What Hunting Dogs Reveal About Human Tick-Borne Disease Risk Babesia in dogs may help predict human risk for tick-borne disease. Investigators studied tick-transmitted infections including Babesia in hunting dogs to determine potential risks to humans. Because dogs and humans share the same outdoor tick habitats, infection patterns in dogs may provide an

Lyme Carditis: A Serious Lyme Disease Complication Lyme carditis is a rare but serious complication of Lyme disease that can slow the heart rate and cause fainting or collapse.
