The goal of this study was to verify if any cognitive and learning ability differences are present between patients affected by learning disorders with and without epilepsy and CSWS. [moh-it.pure.elsevier.com]

The survey presented a clinical vignette of CSWS. The questions addressed treatment choices for that clinical scenario. Surveys were self-administered and collected using an online survey website (www.surveymonkey.com). [scholars.northwestern.edu]

Prognosis The prognosis is related to the underlying disorder. The severity of developmental impairment varies with the type of epilepsy. Early infantile epileptic encephalopathy (Ohtahara syndrome) The prognosis is very poor. [emedicine.medscape.com]

Management options* Seizures are not a major problem as their final prognosis is good. Valproate, lamotrigine, levetiracetam and sulthiame# may be the most appropriate treatments. [epilepsy.com]

The long-term prognosis of this condition is overall poor owing to the persistence of neuropsychological impairment. Therefore, early recognition and effective therapy are necessary to improve long-term prognosis. [link.springer.com]

A long duration of continuous spike and waves during slow wave sleep is the major factor of a poor prognosis. The benign atypical partial epilepsy syndrome bears a close relation to continuous spike and waves during slow wave sleep. [neuroscienceandgenetics.it]
