Movement disorders can be defined as neurological syndromes presenting with excessive or diminished automatic or voluntary movements not related to weakness or spasticity. Both Parkinson's disease (PD) and Huntington's disease (HD) are well-known examples of these syndromes. The high prevalence of comorbid psychiatric symptoms like depression, anxiety, obsessive-compulsive symptoms, hallucinations, delusions, impulsivity, sleep disorders, apathy and cognitive impairment mean that these conditions must be regarded as neuropsychiatric diseases...

Infants with a high-risk distribution of port-wine stains are commonly screened for Sturge-Weber syndrome using brain magnetic resonance imaging. There is no consensus about which port-wine stain phenotypes to screen, optimal timing, screening sensitivity, or whether presymptomatic diagnosis improves neurodevelopmental outcomes. This state-of-the-art review examines the evidence in favor of screening for Sturge-Weber syndrome, based on its effect on neurodevelopmental outcomes, against the risks and limitations of screening magnetic resonance imaging and electroencephalography...

The opioid system is considered a potential therapeutic target in a variety of neurological disorders. Delta opioid receptors (DOPs) are broadly expressed in the brain, and their activation protects cells from hypoxic/ischemic insults by counteracting disruptions of ionic homeostasis and initiating neuroprotective pathways. The DOP agonist D-Ala2-D-Leu2-Enkephalin (DADLE) promotes neuronal survival, mitigates apoptotic pathways, and protects neurons and glial cells from ischemia-induced cell death, thus making DADLE a promising therapeutic option for stroke...

Non-invasive brain stimulation methods, such as Transcranial Magnetic Stimulation (TMS), are widely used worldwide to make causality-based inferences about brain-behavior interactions. TMS-based clinical applications have been shown promising to treat neurological or psychiatric diseases. TMS works by inducing non-invasively electric currents in localized cortical regions thus modulating their excitability levels and ongoing activity patterns depending on stimulation settings: frequency, number of pulses, train duration and intertrain intervals...

REVIEW
Vincent Issac Lau, Robert Thomas Arntfield
In the unconscious patient, there is a diagnostic void between the neurologic physical exam, and more invasive, costly and potentially harmful investigations. Transcranial color-coded sonography and two-dimensional transcranial Doppler imaging of the brain have the potential to be a middle ground to bridge this gap for certain diagnoses. With the increasing availability of point-of-care ultrasound devices, coupled with the need for rapid diagnosis of deteriorating neurologic patients, intensivists may be trained to perform point-of-care transcranial Doppler at the bedside...

REVIEW
Yusuke Niimi, Steven W Levison
There is great interest in the regenerative potential of the neural stem cells and progenitors that populate the germinal zones of the immature brain. Studies using animal models of pediatric brain injuries have provided a clearer understanding of the responses of these progenitors to injury. In this review we have compared and contrasted the responses of the endogenous neural stem cells and progenitors of the subventricular zone in animal models of neonatal cerebral hypoxia-ischemia, neonatal stroke, congenital cardiac disease and pediatric traumatic brain injury...

#10
REVIEW
Iris-Katharina Penner, Friedemann Paul
Fatigue, best described as an overwhelming feeling of tiredness and exhaustion, occurs in the context of various neurological diseases. The high prevalence of fatigue as either a symptom or a comorbidity of neurological disease must be taken seriously, as fatigue interferes with patients' activities of daily living, has a remarkable negative impact on quality of life, and is a major reason for early retirement. The tremendous consequences of fatigue are consistent across neurological diseases, as is the uncertainty concerning its underlying pathophysiological mechanisms...

Hepatic encephalopathy describes the array of neurological alterations that occur during acute liver failure or chronic liver injury. While key players in the pathogenesis of hepatic encephalopathy, such as increases in brain ammonia, alterations in neurosteroid levels, and neuroinflammation, have been identified, there is still a paucity in our knowledge of the precise pathogenic mechanism. This review gives a brief overview of our understanding of the pathogenesis of hepatic encephalopathy and then summarizes the significant recent advances made in clinical and basic research contributing to our understanding, diagnosis, and possible treatment of hepatic encephalopathy...

OBJECTIVE: Neurological dysfunction remains a devastating postoperative complication in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB), and previous studies have shown that inhalation anaesthesia and total intravenous anaesthesia (TIVA) may produce different degrees of cerebral protection in these patients. Therefore, we conducted a systematic literature review and meta-analysis to compare the neuroprotective effects of inhalation anaesthesia and TIVA. DESIGN: Searching in PubMed, EMBASE, Science Direct/Elsevier, China National Knowledge Infrastructure and Cochrane Library up to August 2016, we selected related randomised controlled trials for this meta-analysis...

The alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors are the major mediators of glutamate-mediated excitatory neurotransmission, and are critical for synchronization and spread of epileptic activity. Areas covered: AMPA receptor antagonists have been also developed as antiepileptic drugs and perampanel (PER) is the first highly selective, non-competitive AMPA-type glutamate receptor antagonist that is available on the market. It is approved as adjunctive therapy for the treatment of partial-onset seizures with or without secondary generalization, and for primary generalized tonic-clonic seizures in idiopathic generalized epilepsy, in patients aged ≥ 12 years...

REVIEW
W Todd Farmer, Keith Murai
Astrocytes play essential roles in nearly all aspects of brain function from modulating synapses and neurovasculature to preserving appropriate extracellular solute concentrations. To meet the complex needs of the central nervous system (CNS), astrocytes possess highly specialized properties that are optimized for their surrounding neural circuitry. Precisely how these diverse astrocytes types are generated in vivo, however, remains poorly understood. Key to this process is a critical balance of intrinsic developmental patterning and context-dependent environmental signaling events that configures astrocyte phenotype...

In this invited review article I present a translational perspective and overview of our research on auditory hallucinations in schizophrenia at the University of Bergen, Norway with a focus on the neuronal mechanisms underlying the phenomenology of experiencing "hearing voices". An auditory verbal hallucination, i.e. "hearing a voice", is defined as a sensory experience in the absence of a corresponding external sensory source that could explain the phenomenological experience. I suggest a general frame or scheme for the study of auditory verbal hallucinations which is called Levels of Explanation (LoE)...

BACKGROUND: Population aging is an increasing phenomenon in many countries around the world. It has been estimated that more than one quarter of all older adults experience a mental or neurological disorder or disease such as dementia, depression, anxiety, and substance abuse. Reminiscence is a popular treatment for enhancing well-being in older adults. Previous studies have shown that reminiscence therapy improves the cognitive functions, behaviors, and other psychosocial outcomes in older adult patients...

Cladophialophora bantiana brain abscesses are rare, but are frequently and quickly lethal in transplanted patients. We report the case of a 63-year-old man who had undergone lung transplantation for chronic obstructive pulmonary disease and presented with headaches and a neurological deficit. Magnetic resonance imaging revealed multiple brain abscesses. C. bantiana was identified by DNA sequencing performed directly on cerebral tissue obtained by surgical biopsy. After 6 months of antifungal treatment, the brain abscesses were replaced by ischemic sequelae...

Brain imaging technology has allowed researchers to conduct rigorous studies of the dynamic course of alcoholism through periods of drinking, sobriety, and relapse and to gain insights into the effects of chronic alcoholism on the human brain. Magnetic resonance imaging (MRI) studies have distinguished alcohol-related brain effects that are permanent from those that are reversible with abstinence. In support of postmortem neuropathological studies showing degeneration of white matter, MRI studies have shown a specific vulnerability of white matter to chronic alcohol exposure...
