Abstract:
The clinical variability of chronic infections due to Borrelia burgdorferi is greater than previously thought. Three personal cases are presented in an overview, together with cases from the literature. Chronic spastic para- and quadriparesis, transverse myelitis and recurrent hemiparesis have been noted in such cases. Frequently, there is additional involvement of the cranial nerves. Chronic polyneuritis, mononeuritis multiplex, as well as plexus neuritis can also occur. Psychiatric manifestations can at times be predominant. Their spectrum ranges from agitated depressive states with suicidal ideas to the clinical picture of dementia. Due to the high percentage of positive antibody titre reactions in the normal population, reliable evidence of a chronic infection of the nervous system is based on the examination of the cerebrospinal fluid. Lesions seen on CT and MRI are mostly uncharacteristic and bear no clear-cut relationship to the disease. Neurological signs and symptoms can be improved by antibiotic treatment.
Insights
Chronic Borrelia burgdorferi infections present diverse neurological and psychiatric symptoms, often mimicking other conditions. Cerebrospinal fluid analysis is crucial for diagnosis, and antibiotic treatment can improve outcomes.
Area of Science:
- Neurology
- Infectious Diseases
- Neuroborreliosis
Background:
- Borrelia burgdorferi causes Lyme disease, a tick-borne illness with varied clinical presentations.
- Chronic infections can manifest with significant neurological and psychiatric sequelae.
Observation:
- Case studies reveal extensive clinical variability in chronic Borrelia burgdorferi infections.
- Observed neurological manifestations include spasticity, myelitis, cranial nerve palsies, and peripheral neuropathies.
- Psychiatric symptoms range from depression to dementia.
Findings:
- Cerebrospinal fluid (CSF) examination is essential for diagnosing neuroborreliosis due to unreliable antibody titers in the general population.
- Neuroimaging (CT/MRI) findings are often non-specific.
- Antibiotic therapy shows potential for improving neurological signs and symptoms.
Implications:
- Highlights the need for increased clinical awareness of diverse neuroborreliosis presentations.
- Emphasizes the diagnostic importance of CSF analysis over serology in chronic cases.
- Suggests antibiotic treatment as a viable therapeutic option for neurological manifestations.
