Patients should be warned of Lyme disease complications, including Lyme encephalopathy

It came as a surprise to read that physicians at a Lyme disease clinic, located in an endemic region of New York State, have reportedly never seen a patient with Lyme encephalopathy and question whether it exists. The Lyme Disease Diagnostic Center is a walk-in diagnostic, treatment and research facility for adults 18 years and older suspected of having a tick-borne illness. It has been in business for 27 years and is situated in an area where the number of cases of Lyme disease is steadily rising.

Physicians, including Dr. Gary Wormser who operate the facility, recently published a review article, which states, “We have never seen the poorly defined entity referred to as Lyme encephalopathy and question its existence. We also question the existence of a diffuse axonal peripheral neuropathy as a manifestation of Lyme disease, having never seen a bonafide case.”

The article, “Management approaches for suspected and established Lyme disease used at the Lyme disease diagnostic center,” however, fails to point out that patients treated at the Center are only those who are in the acute phase of the disease and present with objective signs of the disease — an erythema migrans (EM) rash and/or a positive serological test. These individuals do not represent the vast majority of patients. Wormser and colleagues also did not describe the results of patients who had a private appointment with the medical director or other infectious disease physicians at the center.

“We have also never seen Lyme encephalopathy or a diffuse axonal peripheral neuropathy and suggest that these entities are either very rare or nonexistent.”

Lyme encephalopathy has been discussed throughout the medical literature for years and is a recognized medical condition. In fact, Dr. Allen Steere, best noted for discovering Lyme disease, was part of a research team that described Lyme encephalopathy in 1990. [1]

Lyme encephalopathy predominantly affects memory and concentration.

Lyme encephalopathy predominantly affects memory and concentration.

A paper entitled Chronic neurologic manifestations of Lyme disease by Logigian and colleagues reported, “24 of 27 chronic Lyme disease patients presented with a mild encephalopathy that began 1 month to 14 years after the onset of the disease and was characterized by memory loss, mood changes, and sleep disturbances.” The symptoms also included fatigue, headaches, depression, irritability, and difficulty finding words. [2]

The same research team described diffuse axonal peripheral neuropathy. “Most of our patients had peripheral sensory symptoms, either distal paresthesias or spinal or radicular pain. Electrophysiologic testing, particularly in those with distal paresthesias, often showed an axonal polyneuropathy.” [2] They also noted, “sural nerve biopsies in affected patients have shown predominately axonal injury with perivascular infiltration of lymphocytes and plasmacytes around epineural vessels.”

Lyme encephalopathy has repeatedly been described in the literature. In 1999, Logigian and colleagues reported a series of 18 patients with Lyme encephalopathy, who rated themselves as “having improved” or back to normal” following a 4-week course of intravenous (IV) ceftriaxone. [3]

A series of 37 patients with Lyme encephalopathy was studied by Fallon and colleagues. [4] And in an article, Neuroborreliosis: central nervous system involvement, Halperin noted that Lyme disease patients were more likely to develop cognitive and memory impairment than encephalomyelitis. [5] Furthermore, both the 2000 and 2006 Infectious Diseases Society of America (IDSA) guidelines include Lyme encephalopathy and axonal peripheral neuropathy in their Practice guidelines for the treatment of Lyme disease. [6,7]

It is unclear how many patients who are ill upon long-term follow-up would be diagnosed with encephalopathy and/or axonal peripheral neuropathy. Thirty-four percent of a population-based, retrospective cohort study in Massachusetts were found to have arthritis or recurrent arthralgias, neurocognitive impairment, and neuropathy or myelopathy, a mean of 6 years after treatment for Lyme disease. [8]

Meanwhile, 62% of a cohort of 215 consecutively treated Lyme patients in Westchester County were found to have arthralgias, arthritis, and cardiac or neurologic involvement with or without fatigue an average of 3.2 years after treatment. [9]

It’s clear that a significant number of patients treated at the time of an erythema migrans (EM) rash are still sick on long-term follow-up. “Signs of Lyme disease disappeared post-treatment; however, new-onset patient-reported symptoms increased or plateaued over time,” Aucott and colleagues noted. “At 6 months, 36% of patients reported new-onset fatigue, 20% widespread pain, and 45% neurocognitive difficulties.” [10]

Lyme disease can cause numerous complications. These include neuropsychiatric disease, [11] post Lyme disease, [12] uveitis, [13] postural orthostatic tachycardia, [14] and post-treatment Lyme disease. [15] There is also a subset of patients who suffer from ongoing illness, despite antibiotic treatment. These patients report poor functioning and a poor quality of life an average of 4.7 years following treatment. [16]

It’s alarming that a facility treating Lyme disease patients, in the heart of an endemic region, would dismiss Lyme encephalopathy as a legitimate medical complication. Patients should be alerted to the possibility that they may develop future symptoms and to be on the lookout — even if they were treated in the acute stage.

    My health has been failing since August 2013. Four months after a deer tick was dug out of the back of my neck. I have have had my thyroid removed due to tumors. Two parathyroid glands removed. I have seizures but the neurologist says he doesn’t know why. I feel my brain is being squeezed. My eyesight is getting worse. Brain fog, word find, memory loss, muscle pain and loss, bones hurt, I could go on. I had a Dr tell me I have Lyme disease and it’s wreaking havock on my immune system but he said I don’t know what to tell you…Go to New York. I’m a disabled 43 year old single mother of a ten year old that feels like I am a lot older some days. I live in Westford MA. Not one Dr will help me here. I have had positive ANA’S. My therapist thinks I have encephalitis.

      It sounds as if different doctors are weighing in on your illness. It is often easier to find a doctor to look for other diseases but not for Lyme disease. Keep working on getting better.

    My husband has a neuropathy from Lyme that affects his running gait so much that he cannot run any longer causing him great disappointment. I’ve been searching online for someone who might be able to offer hope for a treatment that might improve his gait. Can peripheral neuropathy from Lyme be treated or improved or reversed? He now tests negative for Lyme (after extended antibiotic treatment) after once testing positive. He never had the bullseye rash.

      There are patients with Lyme disease with peripheral neuropathy who have improved. It can be difficult to know how far to go with Lyme disease and when to pursue other treatments.

    I was diagnosed with Anaplasmosis and Lyme’s back in April. I never had the target and never saw the tick. I was diagnosed by symptoms and blood work. Anaplasmosis was confirmed first and Itook antibiotics for it. One Lyme’s was confirmed, I completed a round of antibiotics for it. The infectious disease doctor I saw at one of the best hospitals in Boston has assured me that the best evidence shows no chronic issues with Lyme’s treated in the primary stage. My ongoing symptoms include morning back pain, off and on neuropathy in the toes on my right foot (never had until Lyme’s), and the brain fog and increased challenge recalling words and names.

      At least a third of patients treated early remain ill in published studies by leading medical centers.

    Was diagnosed with autoimmune encephalitis with all autoimmune antibodies coming back negative. Symptoms of cognitive decline, muscle.twitches. behavior changes, catatonia and more, new mild atrophy on MRI after immune therapy was given. 25 years old avid outdoorsman and flea and tick exposure. Positive IGeneX. 4 out of 5 bands positive on labCorp.

    Is it possible to have Lyme encephalitis misdiagnosed as autoimmune?

      Many of the Lyme disease manifestations mimic autoimmune conditions. It can be challenging for the doctor to determine who has an autoimmune condition or tick borne illness.
