Antioxidant Effect of Naringin Demonstrated Through a Bayes' Theorem Driven Multidisciplinary Approach Reveals its Prophylactic Potential as a Dietary Supplement for Ischemic Stroke.

Naringin (NAR), a flavanone glycoside, occurs widely in citrus fruits, vegetables, and alcoholic beverages. Despite evidence of the neuroprotective effects of NAR on animal models of ischemic stroke, brain cell-type-specific data about the antioxidant efficacy of NAR and possible protein targets of such beneficial effects are limited. Here, we demonstrate the brain cell type-specific prophylactic role of NAR, an FDA-listed food additive, in an in vitro oxygen-glucose deprivation (OGD) model of cerebral ischemia using MTT and DCFDA assays.

Receptor for Advanced Glycation End Product, Organ Crosstalk, and Pathomechanism Targets for Comprehensive Molecular Therapeutics in Diabetic Ischemic Stroke.

Diabetes mellitus, a well-established risk factor for stroke, is related to higher mortality and poorer outcomes following the stroke event. Advanced glycation end products(AGEs), their receptors RAGEs, other ligands, and several other processes contribute to the cerebrovascular pathomechanism interaction in the diabetes-ischemic stroke combination. Critical reappraisal of molecular targets and therapeutic agents to mitigate them is required to identify key elements for therapeutic interventions that may improve patient outcomes.

Selective Hand Motor Cortex Lesions Masquerading as "Pseudoperipheral Nerve Palsy".

Strategic cortical lesions involving the hand motor cortex (HMC) presenting acutely as distal upper limb pure motor weakness certainly do need to be differentiated on clinical grounds from "pseudoperipheral palsy." This rare phenotype can imitate peripheral motor nerve deficits and should not be easily overlooked. The isolated "central hand and finger weakness" presenting as an acute onset of varying combinations such as pseudomedian, pseudoradial, and/or pseudoulnar nerve palsy is intriguing to the novice.

Mononeuritis Multiplex as Initial Manifestation of Pure Neuritic Leprosy-A Forgotten Cause: Clinical, Electrodiagnostic and Pathologic Correlations.

Despite being common, polyneuropathy remains a diagnostic challenge for most clinicians. Mononeuritis multiplex (MM) refers to involvement of several or many peripheral nerves at the same or different points in time by a disease process. This report describes a case of an atypical presentation of Hansen's disease (HD) as mononeuritis multiplex in the left lower limb with corresponding radiographic, electrodiagnostic, and histopathological data that confirmed pure neuritic leprosy (PNL).

Hyperacute Paraplegia and Neurovascular (Immuno Vasculotoxic) Catastrophe of Nicolau Syndrome: Primum Non nocere.

A case of Nicolau syndrome (NS) in a 36-year-old adult taking an unusual and devastating hyperacute irreversible paraplegia after an intramuscular injection of benzathine penicillin as a part of routine chemoprophylaxis of her rheumatic heart disease is reported. Although this syndrome is a considerably rare, iatrogenic and underappreciated dermatologic entity, we reiterate in this report, its extracutaneous systemic potential for a catastrophic neurovascular phenomenon and morbidity as well as its possible preventive measures. The apoplectiform onset of T10 flaccid areflexic paraplegia, with the cutaneous hallmark of "embolia cutis medicamentosa" was corroborated by magnetic resonance imaging evidence of centromedullary complete cord involvement from T10 to conus medullaris.

A Viral Polymyositis Masquerade: Life-Threatening Case of Juvenile Dermatomyositis Complicated by Systemic Capillary Leak Syndrome.

This is a case report of an 8-year-old boy who developed an atypical, rare subphenotype of autoimmune inflammatory acute juvenile dermatomyositis (JDM), initially masquerading as viral polymyositis (PM)-like presentation, that was complicated by a hitherto unreported fulminant, life-threatening pediatric systemic capillary leak syndrome (SCLS). We highlight the close differential between viral PM and JDM, the baffling clinical syndromic constellation of hypotension with hemoconcentration - a "shock"-like syndrome, hypoalbuminemia without albuminuria, and generalized edema with the atypical JDM presentation, and stress crucial need to implement early aggressive, multipronged immunomodulatory treatment along with intensive fluid resuscitation which saved the life, this patient from a stormy, and turbulent 4-week clinical illness. This is the first published case description in the current literature of the association of an aggressive subphenotype of JDM and life-threatening pediatric SCLS.

Preventing "Neurophobia": Remodeling Neurology Education for 21-Century Medical Students through Effective Pedagogical Strategies for "Neurophilia".

Neurology has a reputation, particularly as a complex "head-to-toe" discipline for undergraduate medical students. Neurophobia syndrome, a global phenomenon, fundamentally stems from pedagogical deficiencies during the undergraduate curriculum, the lack of vertical integration between basic neurosciences and clinical bedside neurology, the lack of clinical reasoning exercises, cognitive heuristics, and clinical problem-solving, errors in diagnostic competence, and hyposkilia. This ultimately results in poor clinical competence and proficiency in clinical neurology and causes attrition in nurturing a passion for learning the neurology discipline.

"All that spikes is not fits", mistaking the woods for the trees: the interictal spikes--an "EEG chameleon" in the interface disorders of brain and mind: a critical review.

Recent research into mammalian cortical neurophysiology, after 6 decades of Berger's seminal work on electroencephalography, has shifted the older concept of interictal epileptiform activity (IEA) away from that of a mere electrographic graphoelement of relevance to diagnostic implications in epilepsy. Instead, accumulating information has stressed the neuropsychological implications, cognitive and/or behavioral consequence of these electrophysiological events, which are the phenotypic expression of aberrations of actual biophysical cellular function. We feel that this review is germane to neuropsychiatry, however, a rather neglected area of research.

Is the pathology of corticobasal syndrome predictable in life?

Corticobasal syndrome (CBS) has been associated with a heterogeneous spectrum of pathologies with an increasing number of reports of Alzheimer's type pathology. There is, however, no means of predicting pathology of CBS in vivo at present. We compared the clinical features of patients presenting with CBS who have either pathologic changes of classic corticobasal degeneration (CBD) or Alzheimer's disease (AD) at post-mortem to identify predictors of the specific pathological processes in life.

Electroencephalographic cerebral dysrhythmic abnormalities in the trinity of nonepileptic general population, neuropsychiatric, and neurobehavioral disorders.

Subclinical electroencephalographic epileptiform discharges in neurobehavioral disorders are not uncommon. The clinical significance and behavioral, diagnostic, and therapeutic implications of this EEG cerebral dysrhythmia have not been fully examined. Currently the only connotation for distinctive epileptiform electroencephalographic patterns is epileptic seizures.

The spectrum of dementia: frequency, causes and clinical profile. A national referral hospital-based study in Oman.

Background And Objective: There is a paucity of epidemiological data on dementia in the Arabian Peninsular region, particularly Oman. To determine the spectrum, clinical profile, and the behavioral manifestations of dementia in Omani patients evaluated at a tertiary referral hospital.

Methods: We retrospectively reviewed the demographic and clinical spectrum of 116 patients with probable dementia diagnosed in this center.

Frontotemporal dementia in Oman: cognitive behavioural profile and neuroimaging characteristics; a prospective hospital-based study.

Frontotemporal dementia is increasingly recognised as an important cause of early-onset dementia and is considered to be the second commonest neurodegenerative dementia after Alzheimer's disease. We describe the cognitive, behavioural profile and neuroimaging characteristics of 6 patients with frontal variant of Frontotemporal dementia that were evaluated at the cognitive behavioural clinic at this tertiary referral teaching hospital. All patients underwent clinical, neuropsychological, structural/functional neuroimaging, and laboratory evaluations.

A patient with both Gilles de la Tourette's syndrome and chromosome 22q11 deletion syndrome: clue to the genetics of Gilles de la Tourette's syndrome?

This is the first published case description of the association of Gilles de la Tourette's syndrome (GTS) and chromosome 22q11.2 deletion syndrome (22q11DS; previously referred to as CATCH-22 syndrome). The co-occurrence of GTS, 22q11DS, and their behavioral/neuropsychiatric abnormalities may be due to the common endophenotypic mechanisms shared by these disorders, rather than due to specificity for GTS.

The neuropsychiatry and multisystem features of the Smith-Magenis syndrome: a review.

Smith-Magenis Syndrome (SMS) is a complex, pediatric, neurobehavioral, contiguous gene syndrome ascribed to interstitial microdeletion of chromosome 17, band 11.2. The syndrome is characterized by distinctive behavioral, neurocognitive, and neuropsychiatric abnormalities.

The insular lobe of Reil--its anatamico-functional, behavioural and neuropsychiatric attributes in humans--a review.

There is considerable clinical and experimental research to explore the anatamico-functional correlations of the limbic lobe to establish its relevance in modern neuroscience. The insula being a pivotal structure in the concept of the greater limbic lobe, we have attempted to highlight in this review the topographical anatomy and development, the remarkable heterogeneity of the insular cortical architecture, the widespread multifaceted spectrum of functional connectivity patterns and how this is translated to its behavioural specialisation in humans. The insula serves as an intergration cortex for multimodal convergence of distributed neural networks such as the somesthetic-limbic, insulo-limbic, insulo-orbito-temporal and the prefrontal-striato-pallidal-basal forebrain.
