We have examined 48 patients with nervous system disorders caused by Epstein — Barr virus (EBV) as monoinfection or in association with other herpes viruses during their reactivation (n = 34) or persistence (n = 14). With the activation of Epstein — Barr virus infection, arachnoiditis is most often diagnosed — 29.4 %, as well as arachnoencephalitis — 26.5 %, rarely — disseminated encephalomyelitis (DEM) — 11.8 % and encephalitis 11.8 %, encephalopolyneuropathy — 5.9 %, meningoencephalitis — 5.9 %. With persistence of herpes viruses, encephalitis was not detected, arachnoiditis was diagnosed in 28.6 % of patients, arachnoencephalitis — in 28.6 %, and DEM — in 14.3 %. Differences in the detection of neurologic symptoms and syndromes in the group of patients with activation and reactivation are shown as compared with persistence.
