METHODS: A literature review was performed yielding 14 clinical observations of seizure recurrence after discontinuation and its treatment outcome. RESULTS: Seizure recurrence rate after AED ...

BACKGROUND: Pathomorphologic brain changes occurring as early as first-episode schizophrenia have been extensively described. Longitudinal studies have demonstrated that these changes may be progressive and associated with clinical outcome. This raises the possibility that antipsychotics might alter such pathomorphologic progression in early-stage schizophrenia. OBJECTIVE: To test a priori hypotheses that ...

Functional imaging studies with nonfluent aphasia patients have observed "over-activation" in right (R) language homologues. This may represent a maladaptive strategy; suppression may result in language improvement. We applied slow, 1 Hz repetitive transcranial magnetic stimulation (rTMS) to an anterior portion of R Broca's homologue daily, for 10 days in ...

PURPOSE: The emergency treatment of seizures is an important practical issue, in particular the therapy of status epilepticus. Antiepileptic drugs for this condition should be easy to use, show rapid action, have a long-lasting antiepileptic effect, and have minimal cardiopulmonary and other side-effects. Unfortunately, none of the presently available medications ...

OBJECTIVES: To identify prognostic factors which predict the outcome 2 years after TLE surgery in those patients who were not seizure-free at the 6-month postoperative examination. METHODS: We included 86 postoperative TLE patients who had undergone presurgical evaluation, including video-EEG and high-resolution MRI, and who had seizures between the second ...

Cholinesterase inhibitors and memantine have been shown to improve symptoms associated with AD. Mechanisms of action and the pathophysiologic targets are distinct for the 2 classes, but clinical outcomes demonstrate both medications improve patient symptomatology. In addition, memantine and a ChEI appear to produce an additive effect resulting in a ...

OBJECTIVES: To identify predictive factors for the seizure-free outcome of vagus nerve stimulation (VNS). METHODS: All 47 patients who had undergone VNS implantation at one centre and had at least one year of follow up were studied. They underwent complete presurgical evaluation including detailed clinical history, magnetic resonance imaging, and ...
