PURPOSE To determine the predictive value of clinical features and medical history in patients with nonepileptic seizures (NESs). METHODS One hundred sixty-one consecutive ictal video-EEGs were reviewed, and 17 patients with 41 NESs identified. NES diagnosis was defined as paroxysmal behavioral changes suggestive of epileptic seizures recorded during(More)
The issue of psychotic disorders in epilepsy has given rise to great controversy among professionals; however, there are not many studies in this area and the physiopathological mechanisms remain unknown. The aim of this study was to describe the spectrum of psychotic disorders in an Argentine population with refractory temporal lobe epilepsy (RTLE) and to(More)
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)
INTRODUCTION The association between psychotic disorders and epilepsy has been controversial. Different subtypes of psychotic disorders in epilepsy patients have been described according to temporal relationship with seizures-postictal (PIP), interictal (IIP) and bimodal (BP) psychoses are described in literature. OBJECTIVES Determine clinical(More)
We performed a molecular epidemiology study in a population of 105 mesial temporal lobe epilepsy with hippocampal sclerosis (MTE-HS) patients in order to investigate the role of a polymorphism in the serotonin transporter gene (SLC6A4) in the prediction of antiepileptic drug (AED) treatment response. Homozygous carriers of the 12-repeat allele had an almost(More)
Temporal lobe epilepsy surgery has become a successful alternative in patients with refractory epilepsy. However, the outcome of epilepsy surgery may be affected by the occurrence of postsurgical psychiatric symptoms, such as psychosis. This report describes three cases of refractory temporal lobe epilepsy and hippocampal sclerosis, which, after anterior(More)
The present case report is about the development of a eschizophreniform psychosis after epilepsy surgery (anterior temporal lobectomy). This adverse event was the novo, in a patient without a history of previous psychosis. This case have been studied pre and post-surgery, and have been used the DSM IV diagnosis criteria. The patient developed a subacute(More)
Several studies have demonstrated a controversial involvement of NO in epileptogenesis. The aim of this study is to compare the NADPH diaphorase (NADPH-d) reactivity in the temporal cortex between surgical specimens of patients with intractable epilepsy and hippocampal sclerosis and autopsy controls. Brain samples of patients and postmortem controls were(More)
Psychogenic nonepileptic seizures (PNESs) are diagnosed when disruptive changes in behaviour, thinking, or emotion resemble epileptic seizures (ESs), but no paroxysmal discharges are seen on electroencephalogram (EEG) and do not originate from another medical illness. The gold standard for PNES diagnosis is video electroencephalogram (Video-EEG). PNESs are(More)
