What Are the Symptoms of Post-Treatment Lyme Disease Syndrome? Patients with post-treatment Lyme disease syndrome (PTLDS) often have normal lab tests and physical exams—yet their symptoms are real, measurable, and clinically significant. A Johns Hopkins study identified 19 symptoms that help define this often-dismissed condition. Why Standard Tests Often Miss PTLDS In their article published […]

How Long Do PTLDS Symptoms Last? Some patients recover quickly after Lyme disease treatment. Others continue to experience fatigue, cognitive slowing, joint pain, dizziness, or sleep disruption long after antibiotics are completed. Persistent Lyme disease symptoms describe this ongoing clinical phase following infection. In medical research, this pattern is often categorized as Post-Treatment Lyme Disease

Rare Skin Manifestation of Lyme Disease in a Child A 6-year-old girl developed an unusual skin presentation of Lyme disease—highlighting how early infection can be missed when symptoms fall outside typical patterns. The child initially presented with an erythema migrans (EM) rash, followed weeks later by an areolar lymphocytoma involving her breast. She had recently

Single Dose Doxycycline for Lyme Disease: A Case With Poor Outcome A 61-year-old man developed severe neurologic Lyme disease after receiving only a single dose of doxycycline—highlighting the risks of undertreatment in early infection. In the January 2018 issue of the British Medical Journal, Ebner and colleagues describe a patient who presented with severe shooting

Lyme Disease Bacteria Dates Back to the Ice Age Lyme disease may feel like a modern epidemic—but the bacteria behind it is not new. In an effort to understand the evolutionary history of Borrelia burgdorferi, Walter and colleagues at Yale University analyzed one of the largest collections of bacterial genomes assembled to date, using ticks

Delayed Lyme Disease Treatment Leads to Carditis and Vision Loss Lyme disease can progress quickly when early symptoms are overlooked or ignored. A 66-year-old man became ill within one week of a tick bite to the back of his neck. One month later, he collapsed and lost consciousness, according to Sharma and colleagues in The

Using Dogs to Track Lyme Disease Risk in West Virginia Dogs may provide an early warning system for Lyme disease risk in humans. Researchers have long used animal sentinel studies to monitor the spread of Lyme disease. Domestic dogs are particularly useful because of their frequent outdoor exposure, known travel history, and ability to develop

How Borrelia Evades the Immune System Borrelia burgdorferi, the bacterium responsible for Lyme disease, has developed strategies that allow it to persist in the body despite immune responses and standard treatment. To better understand this process, Embers and colleagues studied infection in rhesus macaques—an animal model that closely reflects human Lyme disease. A Model That

Lyme Disease Fatigue: Persistent Pain and Exhaustion After Treatment Lyme disease fatigue is more than feeling tired. Patients often describe a deep, persistent exhaustion that does not improve with rest—and may worsen after even minor activity. For some, fatigue begins early during infection. For others, it develops months later and becomes one of the most
