We study viral infections of the central nervous system (CNS) in children and adults mainly varicella zoster virus (VZV), herpes simplex encephalitis (HSE), herpes simplex virus type 2 (HSV-2) meningitis, tick-borne encephalitis (TBE) and since 2020 also neurological aspects of covid-19. The national burden of different CNS infections are studied.
The research focuses on improving diagnosis with quantitative PCR, intrathecal antibodies and in encephalitis of unknown origin we use next generation sequencing (NGS). We perform long-term follow-up studies with neuroimaging and neurological and cognitive assessments to enable correlation between outcome and biochemical markers in cerebrospinal fluid and blood which may be potentially prognostic. Treatment studies have been performed in HSE and HSV-2 meningitis and future studies are planned.
The main aims are to improve diagnostics in viral CNS infections in cooperation with the Microbiology Department and to find prognostic biomarkers to be used in future treatment studies. The neurological symptoms and signs in covid-19 are explored. Together with neuropsychologists we develop specific assessments for different CNS infections and rehabilitation programs in order to diminish neurological sequels. Finally, we study genetic predisposition in CNS herpes virus infections.
