INTRODUCTION: @entity9144 ( @entity9144 ) is a @entity4767 caused by the spirochete @entity2069 sensu lato. The primary symptoms are usually painful @entity614 , @entity3541 and @entity693 . The aim of this study was to provide data on the seasonal variation, anamnesis, symptoms, laboratory data and course of the disease in adults (>=  16 years). METHODS: The medical records of 69 @entity1 with confirmed @entity9144 who attended the Department of Neurology, Lillebaelt Hospital, Vejle, Denmark, were analysed. The diagnosis was confirmed by the presence of leucocytosis in the cerebrospinal fluid and intrathecal production of immunoglobulin M and/or G anti-B. burgdorferi antibodies. RESULTS: Onset of neurological symptoms in @entity9144 occurred year round in the Region of Southern Denmark. Only half of the @entity1 had a history of a tick bite or @entity8831 ( @entity8831 ). Half of the @entity1 who observed a tick bite subsequently reported @entity8831 . The duration from the onset of neurological symptoms to referral to hospital was remarkably long for @entity1 with radiculoneuritis, whereas the onset of @entity3541 led to a @entity514 referral. @entity1 who were >=  50 years old had a significantly lower age-related risk of @entity3541 without @entity1109 . CONCLUSION: In this study, winter as a low-risk season was not a reliable factor in ruling out @entity9144 . This finding may be relevant when investigating the cause of @entity3541 and @entity1109 . FUNDING: not relevant. TRIAL REGISTRATION: The study was approved by the Danish Data Protection Agency. The study was a data-register study, and therefore the approval of the National Committee on Health Research Ethics was not necessary.
