RESUMEN

Lyme disease (LD) can affect the skin, joints, heart, and nervous system as a multisystemic condition. The cause of the illness is the spirochete of the genus Borrelia. These pathogens can affect the skin, joints, heart, and nervous system. Lyme neuroborreliosis (LNB) is the term for the disease, which occurs when the nervous system gets involved. Regarding geographical distribution, LNB is more prevalent in Europe than in North America. The most significant change in pathogenesis is inflammation of the central nervous system (CNS) and peripheral nervous system (PNS). Furthermore, clinically, it can represent a variety of neurological manifestations, such as meningitis, encephalitis, radiculopathies, and cranial neuritis. However, dementia-like syndrome is an infrequent manifestation of Lyme disease. Our review article aims to summarize the similarities and differences between dementia-like syndrome in LNB and that in primary neurodegenerative diseases, as well as to look for a correlation between the pathogenesis of the disease and the possibility of developing dementia-like syndrome. The world literature lacks sufficiently convincing data on the relationship between spirochete infection and primary dementia syndromes. However, cases of secondary dementia syndrome due to nervous system involvement as well as post-treatment have been described. A thorough examination, medical history, laboratory and imaging studies, cerebrospinal fluid (CSF) examination, MRI, and fludeoxyglucose-18-positron emission tomography (FGD-PET) are required to differentiate between these syndromes.
