BACKGROUND: Establishing a presurgical baseline of neurocognitive functioning for pediatric brain tumor patients is a high priority to identify level of functioning prior to medical interventions. However, few studies have obtained adequate samples of presurgery assessments. METHODS: This study examines the feasibility of completing tests to assess pre-surgical neurocognitive functioning in 59 identified pediatric brain tumor patients. RESULTS: Eighty-five percent of patients (n = 50) were referred by the neurosurgery team before surgery and 83% of patients (n = 49) enrolled in the study...

Bipolar disorder is characterized by affective episodes in the mania-depression spectrum. Ninety per cent of the cases have an onset before age 50. In the patients with late onset mania, white matter hyperintensities (WMH) may be seen in the MRI FLAIR sequence, although these are of uncertain significance. A case-control study was done, including patients with late onset mania attended at the National Institute of Neurology and Neurosurgery, as well as healthy controls which were paired by age, sex, and academic level...

BACKGROUND: Primary intraventricular meningiomas (IVMs) make up 0.5-5% of all intracranial meningiomas and represent one of the most challenging lesions in neurosurgery. METHODS: Between 1990 and 2013, 42 patients (30 female, 12 male, mean age of 43.6 years) underwent the resection of their IVM. The removal was performed by posterior-parietal approach in 19 of the 40 lateral ventricle tumors, and one in the third ventricle meningioma. The transcallosal approach was used for three meningiomas, while other lesions underwent temporal (7 cases) and temporo-parietal approaches (12 pts) respectively...

BACKGROUND: Trigeminal neuralgia (TN) is characterized by paroxysmal pain attacks affecting the somatosensory distributions of the trigeminal nerve. It is thought to be associated with a neurovascular conflict most frequently, but pathomechanisms have not been fully elucidated. In general, no sensory deficit is found in routine clinical examination. There is limited data available, however, showing subtle subclinical sensory deficits upon extensive testing. OBJECTIVE: We used quantitative sensory testing (QST) to detect abnormalities in sensory processing in patients with TN by comparing the affected and non-affected nerve branches with their contralateral counterparts and by comparing the results of the patients with those of controls...

INTRODUCTION: Dural arteriovenous fistulas (DAVFs) is a challenging condition in vascular neurosurgery. Development of new endovascular techniques has progressively modified treatment strategies; however, surgery is still considered a valid option of treatment of this pathology. MATERIALS AND METHODS: From a retrospective analysis of our database, we selected 107 patients who underwent surgical treatment for DAVFs. Patients were grouped into five categories according to the Borden and Cognard classifications...

Subarachnoid hemorrhage (SAH) following rupture of an intracranial is associated with high mortality and morbidity. The late deterioration of the patient's neurological status or late cognitive dysfunctions even after secure clipping or decent endovascular treatment which is defined as delayed ischemic neurological deficits recently has been attributed to vasospasm. Due to the failure of specific anti-vasospastic agents in clinical trials researchers focused to explore new pathological mechanisms to be responsible for the delayed deterioration of the patients suffering from SAH...

Intermittent explosive disorder (IED) is characterized by a difficulty to resist the urge to carry out a recognized harmful behavior. The central symptom is aggressiveness, expressed in isolated episodes. Executive function impairments are habitually found in impulse control disorders. Neuropsychology of impulsivity is related to dysfunctions in the orbito-frontal cortex, dorsolateral cortex and anterior-cingulated regions, being consequently involved in cognitive mechanisms of inhibition. Lesions in those areas are common in IED...
