Svensk definition
Ett sällsynt tillstånd av myelinbortfall i det centrala nervsystemet som ffa drabbar barn och unga människor. Patologiska kännetecken är bl a en stor och tydligt avgränsad och asymmetrisk koncentration av myelinnedbrytning, som kan omfatta en hel lob eller hjärnhalva. Det kliniska förloppet är oftast progressivt och inkluderar demens, kortikal blindhet och dövhet, spastisk hemiplegi och pseudobulbärpares. Balos koncentriska skleros skiljs patologiskt från Schilders diffusa cerebralskleros genom förekomsten av koncentriska ringar av nedbrutet respektive bevarat myelin. Alpers syndrom avser en icke enhetlig grupp sjukdomstillstånd med tecken på fortskridande cerebralt förfall och leversjukdom.
Engelsk definition
A rare central nervous system demyelinating condition affecting children and young adults. Pathologic findings include a large, sharply defined, asymmetric focus of myelin destruction that may involve an entire lobe or cerebral hemisphere. The clinical course tends to be progressive and includes dementia, cortical blindness, cortical deafness, spastic hemiplegia, and pseudobulbar palsy. Concentric sclerosis of Balo is differentiated from diffuse cerebral sclerosis of Schilder by the pathologic finding of alternating bands of destruction and preservation of myelin in concentric rings. Alpers' Syndrome refers to a heterogeneous group of diseases that feature progressive cerebral deterioration and liver disease.
