    In Slovak genetic Creutzfeldt-Jakob disease patients with E200K mutation in the prion protein gene the mean duration of clinical stage is significantly shorter in methionine homozygous then in methionine / valine heterozygous patients (3.70±2.00 vs. 7.84±7.30 months). An atypical prolonged course (13 months) of Creutzfeldt-Jakob disease complicated by malignant neuroleptic syndrome in a 48-year-old methionine homozygous carrier of E200K mutation is reported. Progression was documented by computed tomography, magnetic resonance imaging, functional-biochemical magnetic resonance spectroscopy, and electroencephalography. Post mortem neurohistologic findings confirmed the definitive diagnosis of Creutzfeldt-Jakob disease and revealed severe reduction of cerebral and cerebellar cortex with almost complete depletion of neuronal cells. The possible explanation of unusual duration of the disease in genetic Creutzfeldt-Jakob disease is discussed. The importance of early diagnosis and timely therapeutic intervention (when effective treatment becomes available) sufficiently preceding the development of irreversible degenerative changes if the central nervous system is emphasized.Srednje trajanje kliničkog stadija u slovačkih bolesnika s genetskom Creutzfeldt-Jakobovom bolešću s mutacijom EZOOK u genu prionskog proteina (PRNP) značajno je kraće u bolesnika homozigotnih za metionin nego u onih heterozigotnih za metionin/valin (3,70±Z,OO prema 7,84±7,30 mjeseci). Opisuje se atipičan produljeni tijek (13 mjeseci) Creutzfeldt-jakobove bolesti komplicirane malignim neurolepticnim sindromom u 48-godišnjeg nositelja mutacije EZOOK homozigotnog za metionin. Progresija je dokumentirana kompjutoriziranom tomografijom, magnetskom rezonancom, funkcionalno biokemijskom spektroskopijom magnetskom rezonancom i elektroencefalografijom. Neurohistološki nalazi pri obdukciji potvrdili su definitivnu dijagnozu Creutzfeldt-Jakobove bolesti i otkrili teško smanjenje cerebralnog i cerebelarnog korteksa uz gotovo potpun nestanak neuronskih stanica. Raspravlja se o mogućem objašnjenju neuobičajenog trajanja bolesti u slučaju genetske Creutzfeldt-Jakobove bolesti. Naglašava se važnost rane dijagnoze i terapijske intervencije (kad učinkovita terapija bude dostupna), koje ce dostatno prethoditi razvoju zapaženih ireverzibilnih degenerativnih promjena središnjega živčanog sustava
