Background: Traumatic brain injury (TBI) has been identified as a risk factor for Parkinson's disease (PD). Motor dysfunction among TBI-exposed elders without PD has not been well characterized. We sought to determine whether remote TBI is a risk factor for motor dysfunction on exam and functionally relevant motor dysfunction in day-to-day life among independently living elders without PD. Methods: This is a cross-sectional cohort study of independently living retired military veterans aged 50 or older with (n = 78) and without (n = 85) prior TBI-all without diagnosed PD...

Zoe, a 13-year-old white girl, presents as a new patient to your pediatric clinic with complaints of frequent emesis, anxiety, and learning problems, and previous diagnosis of cerebellar ataxia. Parents accompany Zoe and state, "it is really hard for her to go out, she gets sick and falls easily." She was born full term by vaginal delivery without complications. Given globally delayed milestones, she received early intervention services. Feeding problems began at infancy, including gastroesophageal reflux and aspiration pneumonia...

BACKGROUND: Hypertension is a risk factor for cerebrovascular disease and cognitive impairment. Women who suffer hypertensive episodes during pregnancy report variable neurocognitive changes within the first decade following the affected pregnancy. However, long-term follow-up of these women into their post-menopausal years has not been conducted. OBJECTIVE: The aim of this study was to examine whether women with a history of preeclampsia were at increased risk of cognitive decline 35-40 years after the affected pregnancy...

Moaziz Sarfaraz, Rana Hasan Syeda
Levetiracetam and topiramate are newer anticonvulsants, which is why international data on overdoses of these drugs are lacking. Only a few mild adverse reactions have been noted. These anticonvulsants have been the drug of choice for neurologists. Despite their wide usage, there is a dearth of literature on symptoms and signs of their toxicity. Presented here is the case of a 21-year-old female who overdosed twice on levetiracetam and topiramate. The woman was admitted and discharged after the first overdose...

Low 25-hydroxy vitamin D (25-[OH]-D) serum concentrations have been associated with higher disease activity in multiple sclerosis (MS) patients. In a large cross-sectional study we assessed the vitamin D status in MS patients in relation to seasonality and relapse rate. 415 MS-patients (355 relapsing-remitting MS and 60 secondary-progressive, 282 female, mean age 39.1years) of whom 25-(OH)-D serum concentrations were determined at visits between 2010 and 2013 were included in the study. All clinical data including relapse at visit and expanded disability status scale were recorded in a standardized manner by an experienced neurologist...

The emerging use of mechanical thrombectomy for acute ischemic stroke treatment focuses on the importance of patient selection. Computed tomography perfusion (CTP) is one of widely used techniques. However, the accuracy and reliability of this modality is in debate among vascular neurologists. We present a case of an 80-year-old man admitted because of acute ischemic stroke. CT angiography demonstrated left proximal M2 occlusion. As CTP demonstrated signs of large ischemic core with no significant penumbra, mechanical thrombectomy was not performed following tPA administration...

OBJECTIVE: Currently, neurologists may primarily rely on blood biomarkers, muscle biopsy, MRI, and genetics in the diagnostic work-up of suspected myopathy. Using expert consensus as diagnostic reference standard, this study addressed the added value of electrodiagnostic medicine (EDX) in diagnosis of myopathies. METHODS: One hundred ninety-four EDX evaluations of patients with a peer-review consensus diagnosis of myopathy were collected by seven European centres...

REVIEW
P A Hudgins, A J Fountain, P R Chapman, L M Shah
Lumbar puncture has, for many years, been the responsibility of the internal medicine physician or the neurologist. As more patients have undergone spine surgery and with the current increase in body mass index of the general population, the radiologist has been consulted with increasing frequency to perform lumbar puncture with fluoroscopic guidance. Radiology, in fact, is now the dominant overall provider of lumbar puncture procedures. The procedure is more difficult when the needle length increases, and if fluoroscopy is used, landmarks are more difficult to visualize with increasing subcutaneous fat...

BACKGROUND: Accurate and timely diagnosis of Alzheimer's disease (AD) is important for prompt initiation of treatment in patients with AD and to avoid inappropriate treatment of patients with false-positive diagnoses. METHODS: Using a Markov model, we estimated the lifetime costs and quality-adjusted life-years (QALYs) of cerebrospinal fluid biomarker analysis in a cohort of patients referred to a neurologist or memory clinic with suspected AD who remained without a definitive diagnosis of AD or another condition after neuroimaging...

Anthony D Kauders
The article intends to retrace and review German discourse on hypnotic suggestion from 1900 onward, demonstrating the variety of arguments advanced to account for the social relationship in the hypnotic setting well before the emergence of sociocognitive theory. Using Spanos's distinction between "happenings" and "doings," it shows how, in the case of the "social" in early 20th century German texts on (hypnotic) suggestion, the passive observer, recipient, or victim of hypnosis, a trope familiar to the discipline for many decades, was called into question...

REVIEW
Kalyan B Bhattacharyya
The stretch reflex or myotatic reflex refers to the contraction of a muscle in response to its passive stretching by increasing its contractility as long as the stretch is within physiological limits. For ages, it was thought that the stretch reflex was of short latency and it was synonymous with the tendon reflex, subserving the same spinal reflex arc. However, disparities in the status of the two reflexes in certain clinical situations led Marsden and his collaborators to carry out a series of experiments that helped to establish that the two reflexes had different pathways...

Familial episodic pain is a rare autosomal-dominant disorder characterized by recurrent attacks of pain. The pathogenesis of familial episodic pain is not very clear so far. Essential tremor is the most common movement disorder, but the identification of essential tremor genes has remained elusive. We studied a four-generation Chinese family with early-onset familial episodic pain and adult onset familial essential tremor. All essential tremor diagnoses were confirmed based on a review of the questionnaires, videotaped neurological examinations and was then reconfirmed by a senior neurologist specializing in movement disorders using published criteria...

The teledementia clinic is a new model of care that expands the reach of specialized geriatric and dementia care using clinical video telehealth (CVT) to rural veterans, who frequently lack access to specialty care. The clinic is a Veterans Affairs (VA) Geriatric Research, Education, and Clinical Center clinical demonstration project. It is located in the Pittsburgh VA Healthcare System tertiary referral hospital and serves veterans in affiliated rural community-based outpatient clinics (CBOCs). Rural CBOC primary care providers refer clinic patients, or referral is according to previous cognitive impairment diagnosis in a VAPHS geriatric clinic...

Alemtuzumab is a humanized monoclonal antibody targeting the surface molecule CD52, resulting in a rapid depletion of innate and adaptive immune cells. Infection rates in multiple sclerosis (MS) treatment trials were higher in alemtuzumab than in interferon beta-treated patients. We report two MS patients who developed cytomegalovirus disease within 1 month after the first 5-day cycle of alemtuzumab. Upon identification and appropriate treatment of the infection, each recovered completely. Neurologists should be aware of this serious but treatable complication...

The evolution of neuromyelitis optica spectrum disorder (NMOSD) from a rare, incurable and misunderstood disease with almost universally poor outcomes to its present state in just over a decade is unprecedented in neurology and possibly in medicine. Our knowledge of NMOSD biology has led to the recognition of wider phenotypes, new disease mechanisms, and thus clinical trials of new and effective treatments. This article aims to update readers on the recent developments in NMOSD with particular emphasis on clinical advances, the 2015 diagnostic criteria, biomarkers, imaging, and therapeutic interventions...
