Despite a mostly benign clinical course, aseptic CNS infections can be complicated by paresis. Many viral and bacterial agents can cause CNS infection with paretic complication.
In the Czech Republic neuroborreliosis, tick-born encephalitis and herpes virus CNS infections are the most frequent ones. The article offers a review of paresis associated with aseptic CNS infections and their etiological agents.
Causative treatment is available for some infections provided that the diagnosis is promptly established. CSF examination is recommended in every patient with newly developed paresis.
In adults, the non-infectious cause (stroke, mass lesion etc.) has to be diagnosed first, followed by CSF testing.
