#1
Ian E McCutcheon, Mikhail F Chernov
Given the infiltrative nature of gliomas, controversy has long persisted over the value of their aggressive surgical removal. Nevertheless, in recent decades, the balance of opinion in neurosurgical oncology has shifted from a more nihilistic view that led to many patients' receiving stereotactic biopsy or very limited debulking of lesions for tissue diagnosis only, to more extensive tumor resections which relieve mass effect, lower intracranial pressure, reduce accompanying brain edema, and attenuate dependence on steroids...

Vagus nerve stimulation (VNS) is a therapy for epilepsy and depression. However, its efficacy varies and its mechanism remains unclear. Prior studies have used functional magnetic resonance imaging (fMRI) to map brain activations with VNS in human brains, but have reported inconsistent findings. The source of inconsistency is likely attributable to the complex temporal characteristics of VNS-evoked fMRI responses that cannot be fully explained by simplified response models in the conventional model-based analysis for activation mapping...

Any complaint about memory should be examined. Diagnosis is based on international criteria. Basic evaluation consists of medical history, clinical evaluation, cognitive tests and brain imaging. When a diagnosis of Alzheimer's disease (AD), AD with cerebrovascular disease or with Lewy Body disease (LBD), or Dementia associated with Parkinson's disease or LBD is made, evidence-based medical therapy (acetylcholine esterase inhibitor or memantine) is indicated as a part of comprehensive care. In frontotemporal degenerations, these drugs are ineffective...

In major depressive disorder (MDD), the anterior cingulate cortex (ACC) has been associated with clinical outcome as well as with antidepressant treatment response. Nonetheless, the association between individual differences in ACC structure and function and the response to cognitive behavioral therapy (CBT) is still unexplored. For this aim, twenty-five unmedicated patients with MDD were scanned with structural and resting state functional magnetic resonance imaging before the beginning of CBT treatment. ACC morphometry was correlated with clinical changes following psychotherapy...

The function of dopaminergic neurons in the substantia nigra is of central importance to the coordination of movement by the brain's basal ganglia circuitry. This is evidenced by the loss of these neurons, resulting in the cardinal motor deficits associated with Parkinson's disease. In order to fully understand the physiology of these key neurons and develop potential therapies for their loss, it is essential to determine if and how dopaminergic neurons are replenished in the adult brain. Recent work has presented evidence for adult neurogenesis of these neurons by Nestin+/Sox2- neural progenitor cells...

Glioblastoma multiforme (GBM) is a highly aggressive glial brain tumor with an unfavorable prognosis despite all current therapies including surgery, radiation and chemotherapy. One characteristic of this tumor is a strong synthesis of vascular endothelial growth factor (VEGF), an angiogenesis factor, followed by pronounced vascularization. VEGF became a target in the treatment of GBM, for example with bevacizumab or the tyrosine kinase inhibitor axitinib, which blocks VEGF receptors. To improve patients' prognosis, new targets in the treatment of GBM are under investigations...

BACKGROUND: Proton therapy can reduce the low and intermediate radiation dose to uninvolved brain tissue in children with intracranial ependymomas, which may improve functional outcomes and reduce second malignancies in survivors. Accordingly, ependymoma has become the most common pediatric tumor treated with proton therapy, yet data on efficacy and toxicity are limited. MATERIAL AND METHODS: Between June 2007 and February 2017, 179 children (≤21 years old) with nonmetastatic grade II/III intracranial ependymoma received proton therapy at our institution...

Development of immunotherapy has dramatically changed poor prognosis of metastatic malignant melanoma (MM). Inhibition of immune checkpoints represents a new effective treatment. Monoclonal antibodies against CTLA-4 ipilimumab and against PD-1 (programme death 1) nivolumab and pembrolizumab prolong progression free survival and overall survival (OS) in patients with advanced metastatic MM. Both achieved significant improvement in relapse-free survival and OS also in adjuvant setting. It looks like the efficacy of the combined immunotherapy of ipilimumab with anti-PD-1 antibodies is superior to the monotherapy, but combined therapy is accompanied by higher toxicity...

BACKGROUND: Recent evidence has shown that chronic back pain (CBP) can lead to functional alterations in the circuitry underlying the cognitive control of pain. Thought suppression (TS) is a common type of cognitive control of pain. Previous research has shown that TS has paradoxical effects that may increase the awareness of pain. Pain-related TS may also increase individuals' attention to pain, which may also increase pain sensation, but thus far, the relationship between pain-related TS and structural brain alterations is unknown...

Hepatic encephalopathy (HE) influences short and long-term prognosis. Recently, glycerol phenylbutyrate (PB), that lowers ammonia by providing an alternate pathway to urea for waste nitrogen excretion, has shown that it was effective in preventing the occurrence of HE in RCT. The aim was to assess the benefits of sodium PB in cirrhotic patients admitted in ICU for overt HE, in terms of ammonia levels decrease, neurological improvement and survival. Cirrhotic patients who presented with overt HE, ammonia levels >100 μmol/L, and did not display any contra-indication were included...

Introduction: One of the positive effects of brain stimulation is interhemispheric modulation as shown in some scientific studies. This study examined if a type of noninvasive stimulation using binaural beats with led-lights and sound would show different modulatory effects upon Alfa and SMR brain waves of elderlies and children with some disease types. Subjects: The sample included 75 individuals of both genders, being, randomly, divided in 6 groups. Groups were named elderly without dementia diagnosis (EWD), n=15, 76±8 years, elderly diagnosed with Parkinson's disease (EDP), n=15, 72±7 years, elderly diagnosed with Alzheimer's disease (EDA), n=15, 81±6 years...

BACKGROUND: For patients with a brain metastasis (BM), systemic therapy is usually administered after the completion of radiotherapy, especially in cases of multiple BMs. However, the role of systemic therapy in patients with a limited number of BMs is not clear. Therefore, we conducted a retrospective study to explore this question. METHODS: Consecutive patients with a pathologically confirmed malignancy and 1-3 intracranial lesions that had been documented within the last decade were selected from the databases of three hospitals in China...

Deep brain stimulation of the subthalamic nucleus is an effective treatment for Parkinson's disease symptoms. The therapeutic benefits of deep brain stimulation are frequency-dependent, but the underlying physiological mechanisms remain unclear. To advance deep brain stimulation therapy an understanding of fundamental mechanisms is critical. The objectives of this study were to (i) compare the frequency-dependent effects on cell firing in subthalamic nucleus and substantia nigra pars reticulata; (ii) quantify frequency-dependent effects on short-term plasticity in substantia nigra pars reticulata; and (iii) investigate effects of continuous long-train high frequency stimulation (comparable to conventional deep brain stimulation) on synaptic plasticity...

Glioblastoma (GBM) is the most malignant glioma and represents 29% of all brain tumors. Tumorigenesis is intimately connected with characteristics acquired in the physiologic pathway of cellular death. OBJECTIVE: In the present study, the expression of anti-apoptotic (XIAP and Bcl-2) and apoptotic (cytochrome C, caspase 9, APAF-1), caspase 3 and the Smac/DIABLO genes related to the apoptosis pathway were evaluated in 30 samples of glioblastoma. METHODS: The gene expression was evaluated in 30 glioblastomas (WHO grade IV) and compared to 10 white matter control samples with real-time PCR...

"Psychoanalysis versus psychiatry" and "unconscious versus brain" are classic oppositions between different perspectives on the human being and mental suffering. This article draws on certain elements of this discussion and reflects on how new ideas about the brain and biology favor closer interaction between psychoanalysis and the neurosciences. These questions are redefined through the notion of cerebral plasticity, by which the brain is open to interaction with the social environment and the influence of psychoanalytical therapy...

BACKGROUND: There is increasing evidence that psychotherapy can alter the function of the brain of patients with borderline personality disorder (BPD). However, it is not known whether psychotherapy can also modify the brain structure of patients with BPD. METHODS: We used structural MRI data of female patients with BPD before and after participation in 12 weeks of residential dialectical behavioural therapy (DBT) and compared them to data from female patients with BPD who received treatment as usual (TAU)...

This study examines case reports of brain diseases attributed to inflammation in Richard Bright's Reports of Medical Cases, Volume II. The rationale for the belief that these cases were due to inflammation is discussed in light of theories of inflammation that were current in Bright's time. The consequences of these theories for the therapy of brain diseases are evaluated. The value of Bright's reports lies in the accuracy of the descriptions of a number of brain diseases, featuring descriptions of symptoms or conditions that were novel or not well known in the early nineteenth century...

Deep Brain Stimulation (DBS) is an effective surgical therapy for several neurological movement disorders. The clinical neuropsychologist has a well-established role in the neuropsychological evaluation and selection of surgical candidates. In this article, we argue that the clinical neuropsychologist's role is much broader, when considered in relation to applied psychologists' core competencies. We consider the role of the clinical neuropsychologist in DBS in relation to: assessment, formulation, evaluation and research, intervention or implementation, and communication...
