8(2):18-23. objective incidence of cns acquired demyelinating syndrome (ads), especially multiple sclerosis (ms) in children, appears to be on the rise worldwide. the objective of this study was to determine prevalence, clinical presentation, neuroimaging features, and prognosis of different types of ads in iranian children. materials & methods during the period 2002-2012, all the patients (aged 1-18 years) with ads, such as ms, acute disseminated encephalomyelitis (adem), optic neurotic (on), devic disease, and transverse myelitis (tm), referred to the pediatric neurology ward, nemazee hospital, shiraz university of medical sciences, were included in this study. demographic data, clinical signs and symptoms, past and family history, preclinical findings, clinical course, and outcome were obtained. results we identified 88 patients with ads in our center. the most prevalent disease was ms with 36.5% (n=32), followed by aedm 26.1% (n=31), on 17% (n=13), tm 15.9% (n=14), and devic disease 4.5% (n=4). ms, on, tm were more common among females while adem was more common in males. children with adem were significantly younger than those with other types of ads. family history was positive in 10% of patients with ms. previous history of recent infection was considerably seen in cases with adem. clinical presentation and prognosis in this study was in accordance with those in previous studies on children. conclusion in this study, the most common type of ads was ms, which was more common in female and older age cases. adem was more common in male and younger children. adem and on had the best and devic disease had the worst prognosis. references 1. longer-gould a, zhaug jl, chung j, yeung y, wanbant e, yao j. incidence of acquired cns demyelinating syndrome in a multiethnic cohort of children. neurology 2011;27(12):1143-8. 2. banwell b, kennedy j, sandovnick d, arnold dl, magalhaes s, wambera k. incidence of acquired demyelination of the cns in canadian children. neurology 2009;72(3):232-9. 3. canellas ar, gols ar, izquierdo j.r, subirana mt, gairin xm. idiopathic inflammatory demyelinating disease of central nervous system. neuroradiology 2007;49(5):393-409. 4. renoux c, vukusic s, mikaeloff y. natural history of multiple sclerosis with childhood onset. n engl med 2007;356(25):2603-13. 5. krupp lb, banwell b, tenembaum s;
