Lyme Disease: Stroke-Like Symptoms Explained

Lyme disease is a bacterial infection transmitted by the bite of an infected tick. It can sometimes be misdiagnosed because its symptoms—such as fever, chills, swollen lymph nodes, headaches, fatigue, and muscle aches—are similar to those of a cold or flu. In rare cases, Lyme disease can lead to neurological complications, including stroke. This occurs when the infection causes Lyme neuroborreliosis (LNB), a form of vasculopathy, which can result in cerebral vasculitis and subsequent stroke. While Lyme disease-induced strokes are uncommon, they can have long-term effects, including partial paralysis.

Lyme neuroborreliosis (LNB) can cause strokes

Lyme neuroborreliosis (LNB) is a disease caused by the spirochete Borrelia burgdorferi, which involves the nervous system. While it usually manifests as lymphocytic meningoradiculitis, in rare cases, it can also lead to cerebrovascular complications such as strokes.

In a systematic review of 88 patients with LNB, the most common cerebrovascular manifestation was ischemic stroke (76.1%), followed by transient ischemic attack (11.4%). The overall mortality rate was 4.7%. Ischemic stroke due to Lyme disease is considered rare, but LNB-associated vasculopathy should be considered in patients presenting with acute ischemic strokes, especially in those who live in or have come from areas with a high prevalence of tick-borne diseases.

Lyme disease can, therefore, present with symptoms similar to a stroke, and LNB can, on rare occasions, cause a stroke.

LNB is a rare cause of stroke

Lyme neuroborreliosis (LNB) is a rare cause of stroke. It is a disease caused by the spirochete Borrelia burgdorferi, which involves the nervous system. While it usually manifests as lymphocytic meningoradiculitis, in rare cases, it can lead to cerebrovascular complications such as stroke.

Ischemic stroke due to Lyme disease is considered uncommon. However, there have been reported cases of LNB presenting as acute ischemic strokes with an embolic pattern. In one case, an 83-year-old man was admitted to the emergency room with right-sided weakness and speech difficulties, which had developed over 24 hours. He was diagnosed with LNB, and subsequent treatment with intravenous Ceftriaxone led to a slow improvement.

Another case involved a 76-year-old woman who presented with acute ischemic strokes and unique clinical and radiological findings. The presence of lymphocytic pleocytosis in cerebrospinal fluid and positive Lyme antibodies were compatible with LNB. LNB-associated vasculopathy should be considered in patients presenting with acute ischemic strokes, especially in areas with a high prevalence of tick-borne diseases.

A systematic review of the literature on cerebrovascular manifestations of LNB found that the most common cerebrovascular manifestation was ischemic stroke (76.1%), followed by transient ischemic attack (11.4%). The overall mortality rate was 4.7%. The review concluded that LNB-induced vasculitis is highly responsive to appropriate antimicrobial treatment but can lead to permanent neurological deficits if left untreated.

While LNB is a rare cause of stroke, it should be considered in patients presenting with stroke-like symptoms, especially in endemic areas. A detailed medical history, including tick bites and Lyme disease symptoms, is crucial for prompt diagnosis and treatment.

Stroke patients should be tested for Lyme disease if they come from an endemic area

Lyme disease is caused by a bacterial infection transmitted through tick bites. While most people with Lyme disease develop a tell-tale bullseye-shaped rash around the bite, neurological complications can occur in the second stage of the disease, including Bell's palsy (temporary facial paralysis or weakness), meningitis-like symptoms, and nerve damage in the arms and legs. These neurological complications can appear weeks, months, or even years after the initial bite.

Lyme neuroborreliosis (LNB) is a rare cause of ischemic stroke. However, it is important to consider LNB as a potential cause of stroke in patients from endemic areas with a history of Borrelia burgdorferi infection and no other evident cause of stroke. This is particularly relevant in regions with a high prevalence of tick-borne diseases.

In one case, an 83-year-old man presented to the emergency room with right-sided weakness and speech difficulties, which developed over 24 hours. He had a history of multiple tick bites but no recollection of a skin rash. Testing revealed a recent ischemic lesion in the left corona radiata and a small left parietal lesion. There was no evidence of hypertension, large vessel disease, or a cardiac source. The patient was treated with intravenous Ceftriaxone for 14 days and showed slow improvement.

Another case involved a 76-year-old woman who presented with acute ischemic strokes and an embolic pattern. The clinical course was complicated by pseudo-elevation of autoimmune antibodies and atypical radiological findings. Lymphocytic pleocytosis in cerebrospinal fluid and positive Lyme antibodies confirmed the diagnosis of LNB.

A third case reported a 56-year-old woman from Connecticut who suffered multiple strokes 18 months after receiving antibiotic treatment for early Lyme disease with facial palsy. Pleocytosis, intrathecal synthesis of anti-Borrelia burgdorferi antibody, and her response to antibiotic treatment supported a diagnosis of neuroborreliosis.

Given the potential for Lyme disease to present with stroke-like symptoms and the rarity of LNB, stroke patients from endemic areas should be evaluated for Lyme disease, especially if they have a history of tick bites or potential exposure to ticks. This evaluation can include a detailed medical history, neurological examination, imaging studies, and specific tests for Lyme disease, such as lumbar puncture and Lyme serology.

Lyme disease can be treated with antibiotics

Lyme disease is caused by the Borrelia bacterium, which is spread to humans by the bite of an infected blacklegged tick. Most cases of Lyme disease can be treated with a short course of oral antibiotics, such as doxycycline, amoxicillin, or cefuroxime axetil. The length of treatment depends on the stage of the disease, ranging from 10-14 days for early-stage Lyme disease to three to four weeks for more complicated cases.

The choice of antibiotic and the duration of treatment depend on various factors. Early diagnosis and proper antibiotic treatment can prevent the disease from becoming more severe. Lyme disease can have serious consequences, including acute ischemic strokes with an embolic pattern, as seen in a rare case reported in a 76-year-old woman. This case was complicated by pseudo-elevation of autoimmune antibodies and atypical radiological findings.

While antibiotics are effective in treating Lyme disease, it is important to note that some patients may still experience non-specific symptoms even after successful treatment. These symptoms can include persistent pain, joint and muscle aches, fatigue, impaired cognitive function, or numbness. This condition is known as post-treatment Lyme disease syndrome (PTLDS).

Several clinical trials have been conducted to investigate the efficacy of prolonged antibiotic therapy in treating PTLDS. However, the results have shown no significant benefit, and prolonged antibiotic use may even lead to adverse events and hospitalization in some cases. Therefore, the current recommendation is to treat Lyme disease with the standard course of antibiotics, and more research is being conducted to explore alternative treatment strategies for PTLDS.

Lyme disease can be misdiagnosed as a stroke

Lyme disease is a bacterial infection transmitted by the bite of an infected tick. It is the most common tick-borne illness in Europe and the United States. While Lyme disease typically presents with flu-like symptoms and a distinctive "bull's eye" rash, in some cases, it can lead to neurological complications, including stroke. This occurrence is rare but underscores the importance of considering Lyme disease in stroke diagnosis, particularly in patients from endemic areas with a history of tick bites.

Lyme neuroborreliosis (LNB) is a rare condition caused by the spirochete Borrelia burgdorferi sensu lato, the same bacterium responsible for Lyme disease. LNB can, in exceptional cases, manifest as a stroke due to cerebral vasculitis. This means that the infection can cause inflammation of the blood vessels in the brain, leading to reduced blood flow and oxygen supply, resulting in stroke-like symptoms.

The case of an 83-year-old man in Switzerland illustrates this unusual presentation of Lyme disease. He presented to the emergency room with right-sided weakness and speech difficulties, which had developed over 24 hours. Imaging revealed recent ischemic lesions, but no evidence of other common stroke causes such as hypertension or large vessel disease. The patient's medical history included multiple tick bites, and further testing confirmed the presence of Lyme disease.

Similarly, a 76-year-old woman presented with acute ischemic strokes with an embolic pattern. The unusual case was complicated by pseudo-elevation of autoimmune antibodies and atypical radiological findings. However, the presence of lymphocytic pleocytosis in cerebrospinal fluid and positive Lyme antibodies confirmed the diagnosis of LNB-associated vasculopathy.

These cases highlight the importance of a thorough patient history and appropriate ancillary tests in stroke diagnosis. When stroke symptoms occur in individuals from endemic areas with a history of tick bites, Lyme disease should be considered as a potential cause, even if other typical stroke risk factors are absent.

Lyme disease can be effectively treated with antibiotics, but misdiagnosis or delayed diagnosis can lead to long-term complications, including permanent neurological damage. Therefore, early recognition and appropriate treatment are crucial to prevent potential disability and improve patient outcomes.
