EDITORIAL
Sallie Baxendale
The role of the neuropsychological assessment in the management of people with epilepsy has evolved considerably over the past 25 years. This paper describes some of the most common applications of a neuropsychological assessment in the diagnosis, management and treatment of people with epilepsy. It describes the factors that influence the interpretation of neuropsychological test scores in this patient group and outlines the limitations of the investigation. It gives guidelines for the optimal timing of a referral, together with timelines and indications for reassessment, and provides a checklist to help the referring clinician get the most from a neuropsychological assessment for their patients with epilepsy...

Objective: The feasibility and reliability of neuropsychological assessment at a distance have been demonstrated, but the validity of this testing medium has not been adequately demonstrated. The purpose of this study was to determine the ability of video teleconferencing administration of neuropsychological measures (teleneuropsychology) in discriminating cognitively impaired from non-impaired groups of older adults. It was predicted that measures administered via video teleconference would distinguish groups and that the magnitude of differences between impaired and non-impaired groups would be similar to group differences achieved in traditional administration...

Surgical treatment of elderly patients with meningioma is has proved to be safe, especially when patients are selected using dedicated surgical scores. These scores take into account tumor size, edema, location and patient's co-morbidities. Neuropsychological functioning (NPF) of this kind of patients has been poorly studied in literature and it is not taken into account by these scores. Aim of our study was to describe the long-term outcome in terms of NPF of elderly patients undergoing surgery. Patients older than 70 years of age affected by intracranial meningioma and selected with the Clinical-Radiological Grading Score were included in our study...

REVIEW
Anneli Cassel, Michael D Kopelman
Forgetting has been researched for over a century. This literature highlighted how forgetting rates can vary dependent on factors in the design and method. Recent interest in forgetting revived with evidence suggesting that seizures experienced almost immediately after matched learning could accelerate forgetting. This was followed by a growth in forgetting studies in patients with temporal lobe epilepsy (TLE), including a subset of those with transient epileptic amnesia (TEA). These patients have been described as expressing concerns about memory, yet often perform within 'normal' ranges on standard neuropsychological memory assessments...

OBJECTIVE: This pilot randomized controlled trial compared Cognitive Behavior Therapy (CBT) and Supportive Psychotherapy (SP) for the treatment of depression in bipolar I disorder. We also examined whether exploratory verbal memory, executive functioning, and neural correlates of verbal memory during functional magnetic resonance imaging (fMRI) predicted change in depression severity. METHODS: Thirty-two adults (ages 18-65) with DSM-IV bipolar I disorder meeting current criteria for a major depressive episode were randomized to 18 weeks of CBT or SP...

OBJECTIVES: Generalized tonic-clonic status epilepticus (GTC-SE) is considered a risk for cognitive impairment. Research with standardized tools is scarce and non-conclusive. We systematically assessed short-term and long-term cognitive function after GTC-SE. MATERIALS AND METHODS: Thirty-three patients were tested after the clinical post-ictal phase of GTC-SE (timepoint 1) and again after 1 year (timepoint 2). Twenty controls were examined with the same tests...

BACKGROUND: In many children with unilateral spastic cerebral palsy (USCP), the corticospinal tract to the affected hand atypically originates in the hemisphere ipsilateral to the affected hand. Such ipsilateral connectivity is on average a predictor of poor hand function. However, there is high variability in hand function in these children, which might be explained by the complexity of motor representations of both hands in the contralesional hemisphere. OBJECTIVE: To measure the link between hand function and the size and excitability of motor representations of both hands, and their overlap, in the contralesional hemisphere of children with USCP...

IMPORTANCE: Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system characterized by relapses and a progressive course that may lead to accumulation of physical and cognitive disability. Cognitive training interventions seem to improve the cognitive performance of MS patients. The aim of the present meta-analysis is to quantitatively investigate the effect of computer-based cognitive rehabilitation on the neuropsychological performance of patients with MS...

PURPOSE: With the advent of new very selective techniques like thermal laser ablation to treat drug-resistant focal epilepsy, the controversy of resection size in relation to seizure outcome versus cognitive deficits has gained new relevance. The purpose of this study was to test the influence of the selective amygdalohippocampectomy (SAH) versus nonselective temporal lobe resection (TLR) on seizure outcome and cognition in patients with mesial temporal lobe epilepsy (MTLE) and histopathological verified hippocampal sclerosis (HS)...

OBJECTIVE: Among embedded performance validity tests (PVTs), little research addresses the use of Total Hits and Total False Positives from the California Verbal Learning Test, Second Edition (CVLT-II) in spite of low sensitivity, particularly in psychiatric samples. METHOD: This study examined the classification accuracy of these two measures in individuals with psychiatric disorders or mild traumatic brain injury (MTBI). These samples were separated into two groups using the criteria of passing all PVTs versus failing 2 or more PVTs...

PURPOSE: Precise knowledge of the structural connectivity of white matter fascicles could yield new insights into function and is important for neurosurgical planning. Therefore, we aimed to provide a detailed map of the cortical terminations of the inferior fronto-occipital fascicle (IFOF), with special emphasis on putative inter-individual variations and hemispheric asymmetries. METHODS: Deterministic diffusion tensor imaging-based tractography was used to perform virtual dissection of the IFOF in 20 healthy subjects...

REVIEW
Dale S Sherman, Justin Mauser, Miriam Nuno, Dean Sherzai
Cognitive training in MCI may stimulate pre-existing neural reserves or recruit neural circuitry as "compensatory scaffolding" prompting neuroplastic reorganization to meet task demands (Reuter-Lorenz & Park, 2014). However, existing systematic reviews and meta-analytic studies exploring the benefits of cognitive interventions in MCI have been mixed. An updated examination regarding the efficacy of cognitive intervention in MCI is needed given improvements in adherence to MCI diagnostic criteria in subject selection, better defined interventions and strategies applied, increased use of neuropsychological measures pre- and post-intervention, as well as identification of moderator variables which may influence treatment...

Semantic dementia (SD) is a condition in which atrophy to the anterior temporal lobes (ATL) produces a selective deterioration of conceptual knowledge. As this atrophy is always bilateral but usually asymmetrical, differences in performance of the two SD subgroups-with left > right (L > R) versus right > left (R > L) atrophy-constitute a major source of evidence regarding the roles of the left and right sides of this region. We explored this issue using large scale case-series methodology, with a pool of 216 observations of neuropsychological data from 72 patients with SD...

Introduction: Criteria for mild cognitive impairment (MCI) used in many clinical trials are susceptible to "false-positive (FP)" errors that can be avoided by an actuarial psychometric approach. Methods: Cluster analysis was applied to baseline neuropsychological test data from 756 MCI participants in the Alzheimer's Disease Cooperative Study donepezil trial. Treatment groups were compared after FP MCI cases were removed. Results: Cluster analyses revealed three groups: "single-domain amnestic MCI" (31%), "multi-domain amnestic MCI" (39%), and "FP MCI" (30%)...

Aphasia describes a spectrum of speech impairments due to damage in the language centers of the brain. Insult to the inferior frontal gyrus of the dominant cerebral hemisphere results in Broca's aphasia - the inability to produce fluent speech. The left cerebral hemisphere has historically been considered the dominant side, a characteristic long presumed to be related to a person's "handedness". However, recent studies utilizing fMRI have shown that right hemispheric dominance occurs more frequently than previously proposed and despite a person's handedness...

Stereoelectroencephalography (SEEG) was designed and developed in the 1960s in France by J. Talairach and J. Bancaud. It is an invasive method of exploration for drug-resistant focal epilepsies, offering the advantage of a tridimensional and temporally precise study of the epileptic discharge. It allows anatomo-electrical correlations and tailored surgeries. Whereas this method has been used for decades by experts in a limited number of European centers, the last ten years have seen increasing worldwide spread of its use...

Multiple accounts have been proposed to explain category-specific recognition impairments. Some suggest that category-specific deficits may be caused by a deficit in recurrent processing between the levels of a hierarchically organized visual object recognition system. Here, we tested predictions of interactive processing theories on the emergence of category-selective naming deficits in neurologically intact observers and in patient GA, a single case showing a category-specific impairment for natural objects after a herpes simplex encephalitis infection...
