OBJECTIVE: Verbal fluency functional MRI (fMRI) is used for predicting language deficits after anterior temporal lobe resection (ATLR) for temporal lobe epilepsy (TLE), but primarily engages frontal lobe areas. In this observational study we investigated fMRI paradigms using visual and auditory stimuli, which predominately involve language areas resected during ATLR. METHODS: Twenty-three controls and 33 patients (20 left (LTLE), 13 right (RTLE)) were assessed using three fMRI paradigms: verbal fluency, auditory naming with a contrast of auditory reversed speech; picture naming with a contrast of scrambled pictures and blurred faces...

PURPOSE: To correlate hippocampal volumes obtained from brain structural imaging with histopathological patterns of hippocampal sclerosis (HS), in order to predict surgical outcome. METHODS: Patients with mesial temporal lobe epilepsy (MTLE) with HS were selected. Clinical data were assessed pre-operatively and surgical outcome in the first year post surgery. One block of mid hippocampal body was selected for HS classification according to ILAE criteria. NeuN-immunoreactive cell bodies were counted within hippocampal subfields, in four randomly visual fields, and cell densities were transformed into z-score values...

Patients with epilepsy and obstructive sleep apnea (OSA) are at risk for worsened seizure control and quality of life. We performed a quality improvement project, evaluating for improvements in the screening of OSA in epilepsy patients using the STOP-BANG questionnaire. The electronic medical records of patients seen in our epilepsy clinic were screened for 4 months prior to the intervention. We subsequently implemented the STOP-BANG questionnaire for 3 months. Only 22/664 patients (3.3%) had their sleeping habits explored during the pre-intervention period; 11 (1...

Psychogenic non-epileptic seizures (PNES) are seizures which clinically resemble epileptic seizures but are without concurrent abnormal electrical charges. Though PNES can be just as serious and disabling as epileptic seizures, specific treatment guidelines are lacking, and different types of treatments are used. In this article we address the current research on psychotherapeutic treatment for PNES by discussing recent reviews and six randomized controlled trials (RCTs) on the subject. In conclusion, larger well-designed RCTs are needed in order to support the evidence for psychological interventions for this patient group...

Chronic kidney disease (CKD) is a highly prevalent condition in the world. Neurological, psychological, and cognitive disorders, related to CKD, could contribute to the morbidity, mortality, and poor quality of life of these patients. The aim of this study was to assess the neurological, psychological, and cognitive imbalance in patients with CKD on conservative and replacement therapy.Seventy-four clinically stable patients affected by CKD on conservative therapy, replacement therapy (hemodialysis (HD), peritoneal dialysis (PD)), or with kidney transplantation (KT) and 25 healthy controls (HC), matched for age and sex were enrolled...

OBJECTIVE Craniopharyngiomas remain a particularly formidable challenge in the neurosurgical field. Because these lesions involve the hypothalamus and ophthalmological systems, their resection is associated with either higher rates of mortality and recurrence or a lower rate of radical resection. The authors report the outcomes of aggressive surgeries based on an anatomical subclassification of craniopharyngiomas. METHODS Clinical and ophthalmological examinations, imaging studies, endocrinological studies, neuropsychological function, and surgical complications in all patients who had undergone microsurgical resection for craniopharyngioma at Osaka City University hospital between January 2000 and December 2014 were retrospectively reviewed through the medical records...

INTRODUCTION: There is a presumption that neurocognition is commonly impaired in chronic methadone exposed individuals (CM) when compared with healthy controls (HP). Additionally, it remains unclear if short term (<1year) abstinence (AP) is associated with an altered cognitive profile when compared with CM. METHOD: A random effect model approach was used on data assembled into the Comprehensive Meta-Analysis programme. Cohen's d effect sizes and a significance levels of p<0...

PURPOSE: Posterior fossa arachnoid cysts (PFAC) are mostly considered as benign lesions of the cerebellum. Although many studies have shown the major role of the cerebellum in modulating movement, language, cognition, and social interaction, there are few studies on the cognitive impact and surgical decompression of PFAC. METHODS: We present the cases of two brothers successively diagnosed with PFAC and neuropsychological delay. After multidisciplinary discussion with the boys' parents, it was decided to drain these lesions...

Neurocognitive assessment becomes increasingly important in neuro-oncology. The presence and degree of neurocognitive deficits in patients with brain tumors appear to be important not only as outcome measures but also in treatment planning and as possible prognostic markers for tumor-progression. Common screening methods for neurocognitive deficits are often insufficient in uncovering subtle changes or harbor the risk of being observer-dependent and time-consuming. We present data of brain tumor patients screened by a computer-based neurocognitive assessment tool before and after surgery...

Neuropsychological assessment of human visual processing capabilities strongly depends on visual testing conditions including room lighting, stimuli, and viewing-distance. This limits standardization, threatens reliability, and prevents the assessment of core visual functions such as visual processing speed. Increasingly available virtual reality devices allow to address these problems. One such device is the portable, light-weight, and easy-to-use Oculus Rift. It is head-mounted and covers the entire visual field, thereby shielding and standardizing the visual stimulation...

Schizophrenia is characterized by neuropsychological deficits across many cognitive domains. Cognitive phenotypes with high heritability and genetic overlap with schizophrenia liability can help elucidate the mechanisms leading from genes to psychopathology. We performed a meta-analysis of 170 published twin and family heritability studies of >800 000 nonpsychiatric and schizophrenia subjects to accurately estimate heritability across many neuropsychological tests and cognitive domains. The proportion of total variance of each phenotype due to additive genetic effects (A), shared environment (C), and unshared environment and error (E), was calculated by averaging A, C, and E estimates across studies and weighting by sample size...

Object: Preoperative functional magnetic resonance imaging (fMRI) remains a promising method to aid in the surgical management of patients diagnosed with brain tumors. For patients that are candidates for awake craniotomies, surgical decisions can potentially be improved by fMRI but this depends on the level of concordance between preoperative brain maps and the maps provided by the gold standard intraoperative method, direct cortical stimulation (DCS). There have been numerous studies of the concordance between fMRI and DCS using sensitivity and specificity measures, however the results are variable across studies and the key factors influencing variability are not well understood...

BACKGROUND: The dramatic technological advances witnessed in recent years have resulted in a great opportunity for changing the way neuropsychological evaluations may be performed in clinical practice. Particularly, serious games have been posed as the cornerstone of this still incipient paradigm-shift, as they have characteristics that make them especially advantageous in trying to overcome limitations associated with traditional pen-and-paper based neuropsychological tests: they can be easily administered and they can feature complex environments for the evaluation of neuropsychological constructs that are difficult to evaluate through traditional tests...

REVIEW
Sarah J Wilson, Sallie Baxendale
There has been considerable debate surrounding the benefits and drawbacks of the new approach to classifying the epilepsies released by the ILAE Commission on Classification and Terminology (2005-2009). This new approach has significant implications for the way we conceptualize and assess cognition and behavior in epilepsy; however, as yet, there has been limited discussion of these issues in the field. The purpose of this Targeted Review is to spark this discussion by encouraging researchers and clinicians to think about the changes that the new approach may bring...

OBJECTIVE: To review and summarize data provided by special issue authors regarding the education, training, and practice of neuropsychologists from 14 surveyed countries. METHOD: A table was constructed to present an overview of variables of interest. RESULTS: There is considerable diversity among surveyed countries regarding the education and training required to enter practice as a clinical neuropsychologist. Clinical neuropsychologists are typically well compensated, at least in comparison to what constitutes an average salary in each country...

PURPOSE: Epilepsy surgery has been a standard treatment for refractory epilepsies that cannot be controlled by standard medical treatment. We aimed to evaluate the health and social consequences of resective surgery relative to controls from a study of national data. METHODS: Using the Danish National Patient Registry we identified all subjects with an epilepsy diagnosis between 1996 and 2009 and compared them with a group of patients with an epilepsy diagnosis who had had neither epilepsy surgery nor a vagus stimulation diagnosis by the index date, and who were matched by gender, index year for epilepsy diagnosis, and index year for epilepsy surgery...

REVIEW
Christoph Helmstaedter, Juri-Alexander Witt
Some of the roots of current clinical neuropsychology go back to the early days of epilepsy surgery. Looking back a huge number of publications have dealt with cognition in epilepsy. The major factors driving this work were questions relating to surgery, antiepileptic drugs and, more recently, also to underlying pathology. However, most factors affecting cognition in epilepsy have been discerned many years ago. The body of neuropsychological literature in this field has accumulated much knowledge, raising the question why, apart from epilepsy surgery settings, neuropsychology has still not been fully integrated in the routine care of patients with epilepsy...
