[Results of a prospective standardized study of 30 patients with chronic neurological and cognitive disorders after tick bites].
OBJECTIVE
Patients with chronic neurological disorders and cognitive impairment after tick bites are difficult to manage despite standard antibiotic therapy for Lyme disease. We wanted to correctly assess the disorders.


METHODS
Thirty patients were hospitalized for a standardized evaluation of their disorders: clinical examination, biological and serological studies, cerebral MRI, CSF study, neurophysiological exams, and neuropsychological evaluation of cognitive functions.


RESULTS
Clinical and biological results were non informative. We observed significant CSF abnormalities (64%), MRI Flair pictures (41%), neurophysiological exams (47%), and cognitive evaluation (100%).


CONCLUSIONS
A large and standardized evaluation should be made for each patient to improve the management and probably the treatment of these complex chronic symptoms observed after tick bites.
