Unusual magnetic resonance imaging appearance of multiple cystic lesions in glioblastoma multiforme.
We report a case of a 41-year-old man who presented with a brief history of left lower extremity weakness and sensory loss. Magnetic resonance imaging demonstrated multiple ring-enhancing lesions in the right frontal and parietal lobes. Neuroradiology interpretation was felt to be unlikely for a neoplastic process. The patient underwent stereotactic brain biopsy, which was diagnostic for glioblastoma multiforme. This case demonstrates the importance of histological confirmation of intraaxial brain lesions whenever feasible. The course of his disease and treatment are discussed and the literature reviewed. ...

Bilateral globus pallidus internus deep brain stimulation in Parkinson's disease with periodic limb movement disorder.
Abstract Deep brain stimulation for Parkinson's disease is a well-established therapeutic intervention for refractory disease. The main nuclear targets are the subthalamic nucleus and the globus pallidus internus. Periodic limb movements are often an associated condition in patients with Parkinson's disease. Both conditions can respond to dopaminergic agents. The case of a 57-year-old man with severe Parkinson's disease and periodic limb movement who underwent bilateral globus pallidus deep brain stimulation surgery for his Parkinson's disease is presented and discussed. Intraoperatively the patient's...

Why Humans Like to Cry
Michael Trimble , a British professor at the Institute of Neurology in London, begins his new book with Gana the gorilla. In the summer of 2009, 11-year-old Gana gave birth to a boy at a Muenster zoo. But one day in August, the baby suddenly and mysteriously died. Gana held up her son in front of her, staring at his limp body. She held him close, stroking him. To onlookers it appeared that Gana was trying to reawaken him, and, as the hours passed, that she was mourning his passing. Some at the zoo that day cried. But Gana did not. Humans, Trimble tells us, are the only creatures who cry for emotional reasons. Why Humans L...

How Video Games Change the Brain (preview)
I am in an overgrown lot leaning against an eight-foot-tall shipping container. I look both ways, weighing my options. A man with an assault rifle is looking for me, just as I am looking for him. Hoping for a better vantage point, I run toward the abandoned car to my right. A metallic bang rings out as my opponent's shot hits the wall I have just left. I dodge around the next container, then circle behind it. Raising my M16, I peer through the scope as I run. There he is! I hit the track pad of my laptop hard and fast, but my aim is wobbly. I miss. He spins, fires, and I'm dead. [More]

Reliability of two clinically relevant fiber pathways reconstructed with constrained spherical deconvolution
The single diffusion tensor model is inadequate for the reconstruction of fiber pathways in brain regions with multiple fiber orientations. To overcome this limitation, constrained spherical deconvolution has been proposed. A high reliability of constrained spherical deconvolution is, however, a pre‐requisite for its use in clinical applications. Reliability of reconstructed fiber pathways can be assessed in terms of architectural (addressing their spatial configuration) and microstructural (addressing diffusion‐derived measures along the fibers) reproducibility. We assess the reliability for two clinically relevant fi...

Formaldehyde metabolism and formaldehyde‐induced stimulation of lactate production and glutathione export in cultured neurons
Abstract Formaldehyde is endogenously produced in the human body and brain levels of this compound are elevated in neurodegenerative conditions. Although the toxic potential of an excess of formaldehyde has been studied, little is known on the molecular mechanisms underlying its neurotoxicity as well as on the ability of neurons to metabolize formaldehyde. To address these topics we have used cerebellar granule neuron cultures as model system. These cultures express mRNAs of various enzymes that are involved in formaldehyde metabolism and were remarkably resistant towards acute formaldehyde toxicity. Cerebellar granule neu...

Word‐finding difficulties confound performance on verbal cognitive measures in adults with intractable left temporal lobe epilepsy
This study sought to determine if word‐finding difficulties (WFDs), which are common in adults with dominant temporal lobe epilepsy (TLE), are related to performance on verbal cognitive measures, including memory. One hundred six individuals with left TLE and pathologically confirmed mesial temporal sclerosis completed comprehensive preoperative neuropsychological evaluations. Patients were divided into two groups based on the degree of benefit received from phonemic cueing on a confrontation naming task. Cognitive performance was then compared between patients with greater and fewer WFDs. Patients with greater WFDs demo...

Examining factors related to accelerated long‐term forgetting in epilepsy using ambulatory EEG monitoring
Summary PurposeSome patients with epilepsy demonstrate normal memory when this is tested at relatively short intervals (e.g., 30 min), but substantial loss over longer delay periods (e.g., days or weeks) when compared to healthy control subjects. This pattern of “accelerated long‐term forgetting” (ALF) affects the everyday lives of patients, yet goes undetected by standard neuropsychological memory tests, and its pathophysiologic basis is poorly understood. By testing memory over a period of concurrent ambulatory electroencephalography (EEG), the current study aimed to investigate possible factors contributing to AL...

Altered transporter‐mediated neocortical GABA release in Rasmussen encephalitis
Summary To learn whether epileptic seizures in Rasmussen encephalitis (RE) may be promoted by insufficient γ‐aminobutyric acid (GABA) release. 3H‐GABA was released from neocortical synaptosomes through transporter reversal following intrasynaptosomal Na+ accumulation by veratridine that prevents inactivation of Na+ channels. Tissues of three RE patients were compared with those of nine non‐RE. In RE, the release was markedly reduced. In non‐RE, the extracellular Ca2+ concentration ([Ca2+]e) was inversely related to the amount of release. In RE, the percental decline of additional release upon withdrawal was linked...

Antiepileptic drug treatment in pregnancy: Changes in drug disposition and their clinical implications
This article aims to review the literature on gestational effects on the pharmacokinetics of older and newer generation AEDs and discuss the implications for the treatment of epilepsy in women during pregnancy. Pregnancy can affect the pharmacokinetics of AEDs at any level from absorption, distribution, metabolism, to elimination. The effect varies depending on the type of AED. The most pronounced decline in serum concentrations is seen for AEDs that are eliminated by glucuronidation (UGT), in particular lamotrigine where the effect may be profound. Serum concentrations of AEDs that are cleared mainly through the kidneys, ...

Neuro-Behçet¿s disease in childhood: A focus on the neuro-ophthalmological features
Neuro-Behcet's disease (NBD) involves the central nervous system; peripheral nervous system involvement is not often reported. NBD is quite common in adult patients and occurs rarely during childhood and adolescence. Young patients may share symptoms and signs of NBD with other neuro-ophthalmological disorders (e.g. idiopathic intracranial hypertension); thus, making the differential diagnosis difficult. Neuroimaging is mandatory and necessary for a correct NBD diagnosis but in children radiological examinations are often difficult to perform without sedation. From 1971 to 2011, 130 patients aged

Molecular mechanisms of central leptin resistance in obesity.
Abstract The rapidly increasing prevalence of obesity confers a huge health burden globally. The hypothalamus plays a central role in the regulation of energy homeostasis by integrating multiple metabolic signals from peripheral organs and modulating feeding behavior and energy metabolism. Leptin, a key appetite-regulating hormone derived from the white adipose tissue, primarily acts on hypothalamic neurons to activate catabolic pathway and inhibit anabolic pathway, which can result in anorexia and weight reduction. Despite striking obesity resulting from leptin deficiency, treatment with this hormone in human obes...

Developmental Delay Revisited
This article presents current neurobiological concepts that highlight the critical role of chronological age in determining optimal development. The role of sensitive periods, experience expectancy, gene expression, and gene–age interactions is discussed. The debate between “splitters” and “lumpers” is presented in light of the review articles in this special issue. The conclusion from this study is that in a significant proportion of cases, earlier diagnoses are possible, avoiding the all‐encompassing developmental delay/global developmental delay, and opening up possibilities of early interventions. It is fur...

Early Developmental Cues for Diagnosis of Attention Deficit/Hyperactivity Disorder in Young Children
Attention deficit hyperactivity disorder (ADHD) is a childhood‐onset disorder that is considered one of the most common neurobehavioral disorders. The symptoms of ADHD should be cast, not as static or fixed neurobehavioral deficits, but rather in terms of underlying developmental processes. Targeting attentional disorders early in life can bring about fundamental alterations in the pathogenesis of ADHD, and thus prevent or moderate the course of the disorder. The developmental approach can enable predictions concerning characteristics of ADHD that develop over time and inform us about multiple risk and protective factors...

Identifying Early‐Risk Markers and Developmental Trajectories for Language Impairment in Neurodevelopmental Disorders
The effective identification of neurodevelopmental disorders is essential for early diagnosis and provision of intervention services. For many of these conditions, one of the primary domains of abnormality is language development. This review addresses what is known about the earliest indicators of language impairment across a range of neurodevelopmental disorders; consideration is given to both behavioral and neural markers, as well as patterns of change over time. A summary of the current state of the field, including challenges in research, is presented. The earliest features of the language phenotype in Down syndrome, ...
