Surgery can be highly effective for treating certain cases of drug resistant epilepsy. The current study tested a novel, non-invasive, surgical strategy for treating seizures in a rat model of temporal lobe epilepsy. The surgical approach uses magnetic resonance-guided, low-intensity focused ultrasound (MRgFUS) in combination with intravenous microbubbles to open the blood-brain barrier (BBB) in a transient and focal manner.

The causes of hypercalcaemia in the neonate and infant are varied, and often distinct from those in older children and adults. Hypercalcaemia presents clinically with a range of symptoms including failure to thrive, poor feeding, constipation, polyuria, irritability, lethargy, seizures and hypotonia. When hypercalcaemia is suspected, an accurate diagnosis will require an evaluation of potential causes (e. Read More

Over the past 50 years, published studies have provided quantitative data on the control of epileptic seizures during pregnancy. The studies have varied in quality, and particularly in the ways in which seizure control has been assessed. However, most studies have shown that seizure occurrence rates are more likely to worsen than improve during pregnancy, though in most pregnancies the rates have been unaltered. Read More

In about a third of the patients with epilepsy the seizures are not drug-controlled. The current limitation of the antiepileptic drug therapy derives from an insufficient understanding of epilepsy pathophysiology. In order to overcome this situation, it is necessary to consider epilepsy as a disturbed network of interactions, instead of just looking for changes in single molecular components. Read More

BACKGROUND Convexal subarachnoid hemorrhage (cSAH), a rare form of non-aneurysmal subarachnoid hemorrhage, is confined to cerebral convexities without extension into basal cisterns or ventricles. Typical presentation includes thunderclap/progressive headache or transient focal neurological symptoms; rare manifestations include seizures, intractable vomiting, or altered mental status. Here, we report the first case of convexal subarachnoid hemorrhage and multifocal ischemic lesions caused by infective endocarditis (IE) in a treatment-naïve advanced HIV patient. Read More

Electroencephalogram (EEG) recording is essential in the evaluation of complex movement and behaviors during sleep, but in particular for differentiating epileptic versus nonepileptic events. In general, epileptiform discharges occur with greater density in the first few nonerapid eye movement cycles, and approximately 12% to 20% of seizures occur exclusively at night. This review examines the epilepsy types and syndromes whose presentation is strongly influenced by the sleep state, with an appraisal about the role that sleep plays in facilitating seizures, while deleaneatign EEG findings and clinical manifestation.

Purpose: Children with cerebral visual impairment (CVI) often have abnormal visual orienting behaviors due to impaired or damaged visual cortex. Alternatively, visual-cortical function is intact but visual information is not transformed downstream into an appropriate oculomotor output (visuomotor dysfunction). We examined visual, anatomic, and oculomotor assessments to distinguish visuomotor dysfunction from CVI associated with severely reduced visual-cortical response. Read More
