Stroke as a manifestation of Lyme disease

Strokes should be added to the list of manifestations of Lyme disease based on a 2007 systematic review published in Frontiers in Neurology. [1] The authors identified 88 patients in the literature presenting with cerebrovascular course of Lyme neuroborreliosis (LNB).

More than half of the cases were from three countries: 16 (25.4%) from Germany, 9 (14.3%) from Switzerland, and 8 (12.7%) from France. Five cases (8%) were from the United States, notes Garkowski from the Medical University of Białystok in Poland. [1]

Many of the cases involved relatively young patients, with more than 50% under the age of 50. The authors identified 15 pediatric cases, noting the youngest to be 4 years of age. Patients ranged between 4 and 77 years old with a median age of 46. Males represented 54% of all the cases.

The most common cerebrovascular manifestation of LNB was ischemic stroke (76.1%), followed by [transient ischemic attack] (11.4%), according to Garkowski. [1] “The posterior circulation was affected alone in 37.8% of patients, the anterior circulation in 24.4% of patients, and in 37.8% of cases, posterior and anterior circulations were affected simultaneously.”

A complete response to antibiotic treatment occurred in 75% of the patients. The authors defined a complete response as, “halted progression of the disease and no recurrence of cerebral ischemia or recuperation from neurological deficits.” The mortality rate was 4.7%. The outcome for the remaining 20% was incomplete or incomplete with residual neurologic deficit.

The authors suggest prompt evaluation of prodromal syndromes. “The lack of awareness of this manifestation of LNB might result in the delay of diagnosis, which might lead even to the patient’s death,” warns Garkowski. [1] “Several weeks/months before stroke onset, prodromal symptoms suggesting LNB [Lyme neuroborreliosis], such as meningitis, cranial neuritis or radiculoneuritis, should prompt extensive diagnostics including CSF [cerebrospinal fluid] examination.”

Takeaway: Physicians should consider cerebral vasculitis and stroke due to Lyme neuroborreliosis in patients living in or having visited areas endemic for tick-borne diseases, and in those individuals who don’t have any cardiovascular risk factors but who exhibit stroke-like symptoms with no known cause.

    hi doc 😉
    very interesting article! around 15 years ago when i was still trying to get a correct diagnosis for my MISDIAGNOSIS of chronic lyme, i had a mri done.

    it showed a MINI-STROKE with “old blood”. since i was misdx for 35 years, this stroke could have occurred during this time period.

    is there some type of guideline to determine how long it’s been since any patient had a stroke? thanks doc!

      Good question. At least we are having a conversation.

    I have had Lyme disease with Ehrlichia since 2012. An MRI said I had a stoke and a spinal tap revealed rare white blood cells. I am still sick after being put on a PICC line and 4 1/2 years of antibiotics. I suffer confusion, headaches, stiff neck, nausea,and extreme weaknesses and fatigue, nausea and severe brain fog. My head hurts so bad at the back of my head. I would like to be evaluated by the Dr. I have made no improvement in my condition. My skin burns and stings.
    Please get back with me.

      It is difficult to tell whether a different approach might work. Feel free to call the office at 914 666 4665 if you have any questions.
