OBJECTIVE The purpose of this study is to identify specific clinical-electroencephalogram (EEG) patterns at seizure onset in patients with hippocampal sclerosis (HS). METHODS Sixty-six ictal video-EEG recordings corresponding to 26 patients with HS have been reviewed, focusing on the EEG features found during the first 30 ictal s. The EEG activity has(More)
PURPOSE The goal of this study was to assess the cognitive function status in patients with mesial temporal lobe epilepsy and hippocampal sclerosis (TLE+HS) to determine their cognitive function profile and to correlate material-specific memory deficits with HS laterality diagnosed by MRI. METHODS Seventy-one patients were assessed with a(More)
Antiepileptic drugs (DAEs) act through different mechanisms of action: increase in central inhibition, inhibition of excitatorios mechanisms and modification of the excitability through their action on the ionic channels. Epilepsy is characterized by an abnormal and hypersynchronic unloading of a neuronal population. The activity of numerous drugs is(More)
OBJECTIVE To describe clinical features of epilepsy secondary to Malformation of Cortical Development (MCD) in a series of adult patients. MATERIALS AND METHODS We searched our database for all cases with confirmed epilepsy and MCD and included in the study only those with complete data. Mean age, sex, age at seizure onset (ASO), seizure types, abnormal(More)
Developmental malformations are brain abnormalities that occur during embryogenesis. Neuronal migration disorders, including heterotopic lesions, constitute one type of such abnormalities. The aim of the study was to compare the epileptic clinical patterns of patients with periventricular nodular heterotopia (PNH) (G1) with those affected by subcortical(More)
We describe a patient who showed cystic lesions in the midbrain and obstructive hydrocephalus. MR imaging features corresponded to abnormal dilatation of perivascular spaces. Similar clinical and MR imaging findings were described in previous reports of patients presenting with mesencephalo-thalamic expanding lacunae; the diagnosis of some of those cases(More)
OBJECTIVE The aim of the present study was to assess visual alterations in a population of Argentine patients treated with the antiepileptic drug vigabatrin. METHODS Twenty patients receiving vigabatrin and 15 patients receiving carbamazepine were examined with automated perimetry using a Humphrey 120-point full screening strategy. In addition, scotopic(More)
