Long-Term Problems in Lyme Neuroborreliosis: What Studies Show
Long-term problems in Lyme neuroborreliosis (LNB) may be less severe at a population level—but individual patients can still experience meaningful declines in health and function.
A large European study examined long-term survival, health, education, and social outcomes in patients with Lyme neuroborreliosis.
Overall, the authors found no significant differences compared with the general population in areas such as education level, marriage or divorce rates, and mortality.
Functional Outcomes After Lyme Neuroborreliosis
The study concluded that Lyme neuroborreliosis has minimal impact on the ability to work for most patients.
Rates of disability were relatively low, with prior studies reporting:
- 12% disability at 5 years (Sweden)
- 5% disability after ~3 years (Denmark)
These findings suggest that many patients recover well after treatment.
A Different View: Economic and Health Impact
Despite reassuring population-level data, other findings suggest a more complex picture.
Patients with Lyme neuroborreliosis had a higher socioeconomic status before diagnosis—but experienced declines afterward.
Average annual income dropped from approximately $262K to $230K over 10 years, while income increased in control populations.
This suggests that even “recovered” patients may experience lasting functional or economic effects.
Additional Health Risks
The study also found increased risks for certain conditions, including:
- Lymphoma
- Myeloma
- Chronic lymphocytic leukemia
There was also a short-term increased risk of arthritis and cerebral infarction during the first year after diagnosis.
Important Study Limitations
Several limitations may affect how these findings are interpreted:
- Patients with illness longer than one year were excluded
- The study did not evaluate post-treatment Lyme disease syndrome (PTLDS)
- Clinical symptom data were limited due to lack of chart review
- Patients were not involved in study design or outcome selection
These factors may underestimate the burden of persistent symptoms.
Clinical Perspective
Other studies have reported that a significant proportion of Lyme patients continue to experience symptoms years after treatment.
Persistent neurologic symptoms, cognitive dysfunction, and fatigue may not be fully captured in large population studies.
As a result, outcomes may appear favorable overall while masking challenges faced by individual patients.
Clinical Takeaway
While many patients with Lyme neuroborreliosis recover, long-term problems can still occur. Individual outcomes may differ from population averages, underscoring the need for ongoing clinical follow-up.

Symptoms • Testing • Coinfections • Recovery • Pediatric • Prevention
There are so many study flaws here it would take days to illiterate them. The most glaring was that patient outcomes were only observed a year out, and all of these patients had been treated. Multisystem illness and disabling symptoms vary in characteristics and intensity and develop over individual timelines and respond differently to treatment. There are so many variables to be considered with tick-borne diseases! The disability incidence related to Lyme in the US appears very different when reviewing information from My Lyme Data, a patient-driven study including 10,000 patients over a period of several years.
I also found the “lack of association” findings troublesome. For instance, the statement that neuroborelliosis was not assiciated with increased MS. First, by the time someone’s immune system is dysregulated to the point of autoimmunity, there is decreased likelihood of testing positive for borellia antibodies. In anyone, testing for antibodies to infection that by nature avoids detection and impedes antibody production is ludicrous to begin with. The sickest patients don’t make appreciable antibodies. Coinfections further confound immune aberrations, symptom picture, and diagnosis. My experience as a patient and cardio/neuro nurse tells me that it is rare indeed for a neurologist to give any credence to the idea of persistant neuroborelliosis, even at so-called world class teaching institutions, much less link it to MS. I doubt very many MS patients in Europe are ever worked up properly for borelliosis. At best maybe an ELISA, which in this population misses virtually all cases. Then of course these patients are duly placed on immunosuppressants, masking symptoms and stoking the disease process. Their treatment eventually kills them. So of course the study finds no link. Especially one year out.
A similar scenario plays out with cardiac complications, which I believe are not as rare as supposed. A cardiologist might think of borellia with a case of severe carditis and heart block. This person is at the extreme of the spectrum. They are likely hospitalized and young, and at least in my hyper-endemic area, hospital labs nearly always miss detecting the infection. Occasionally the test is positive, and even then the doctor must be coached on how to interpret results. So borellia must be a rare cause. Not so fast. The rarity is detecting causation accurately. More common manifestations are arrhythmias. Coinfections like bartonella can also contribute. I have never seen a cardiologist consider these infections in new onset arrhythmia patients. And the older the patient, the less suspicion. When prompted, some have humored me and ordered testing. Occasionally the poor lab tests will reveal infection. Some I have counseled where to get better testing and work up after discharge. A few return and tell me they do indeed have Lyme.
Until we have definitive testing, a better understanding of pathology, and include tick infections on differential diagnoses, little can be said about the scope of the impact Lyme has on health.
I feel this study is so bogus. I feel this study was designed to deceive and control those who are unable to recognize LD issues or even awaken an interest to a growing problem. Again, Those deniers will get it when they get it.
