STUDY OBJECTIVES: This study sought to investigate perceptions of sleep disruptions among patients and staff in the inpatient neurology setting. The objectives were to explore the differences between these groups regarding factors that impact sleep, identify the most significant sleep disruptions, and examine the barriers and opportunities suggested to improve inpatient sleep. METHODS: A survey-based observational study was conducted on a 25-bed inpatient neurology unit at an academic medical center...

PURPOSE: There is limited knowledge on the reliability of risk of bias (ROB) tools for assessing internal validity in systematic reviews of exposure and frequency studies. We aimed to identify and then compare the inter-rater reliability (IRR) of six commonly used tools for frequency (Loney scale, Gyorkos checklist, American Academy of Neurology [AAN] tool) and exposure (Newcastle-Ottawa scale, SIGN50 checklist, AAN tool) studies. METHODS: Six raters independently assessed the ROB of 30 frequency and 30 exposure studies using the three respective ROB tools...

BACKGROUND: There have been conflicting results on the effect of auditory stimulation on the vestibulo-ocular reflex (VOR) with some studies indicating suppression, enhancement, or no effect. No studies to date have assessed the effect of sound source location on VOR gain or the relationship between spatial hearing ability and VOR gain. PURPOSE: The purpose of the present study was to determine if VOR gain was affected by moving the location of the sound source within participants and to determine if these effects were related to spatial hearing ability...

OBJECTIVE: Autonomic dysregulation is common in many medical conditions and can have a widespread, negative impact on multiple bodily systems, leading to poorer health outcomes. Thus, addressing autonomic dysregulation as part of a comprehensive treatment plan is important. The goal of this paper was to gain a better understanding of the physiological benefits of a mindfulness-based intervention (MBI) for a population with medical conditions, using validated, objective measures of autonomic functioning...

INTRODUCTION: Tibial deformities are common, but substantial concern may be associated with corrective osteotomy regarding major complications reported in classic literature. Such studies chiefly focused on high tibial osteotomy, with relatively little investigation of other areas and types of deformity. The primary aim of this study was to identify the rate of compartment syndrome, vascular injury, nerve injury, and other major complications after elective tibial osteotomy. METHODS: One hundred eight tibia osteotomies performed during 2019 to 2021 were evaluated, representing all tibia osteotomies except situations of existing infection...

This case offers a safe and effective method for treating lumbopelvic dissociation in a pediatric patient with cauda equina syndrome using a triangular osteosynthesis construct. After a high-speed accident, an 11-year-old girl was admitted to the hospital with bowel and bladder incontinence and bilateral lower extremity weakness. The orthopaedic trauma and spine teams elected for surgical treatment with a triangular osteosynthesis construct, a procedure usually reserved for adults. The surgery was uncomplicated, and the patient experienced complete resolution of her preoperative symptoms...

Cluster headache (CH) is the most common and devastating autonomic headache with multiple and recent advances in treatment. However, it usually goes unrecognized and is found to have a delayed and inappropriate treatment. This paper aims to review the current therapeutic options for patients with CH. We conducted a narrative literature review on the treatments available for this condition using the American Academy of Neurology (AAN) classification of therapeutic evidence. We found effective and safe pharmacological and non-pharmacological therapies with heterogeneity of clinical trial designs for patients with CH, and they are divided into three phases, namely, transitional, acute, and preventive interventions...

Although the field of neurology was dominated by men at the time the American Academy of Neurology (AAN) was founded in 1948, women were involved from the inception of the organization, albeit in limited numbers. This historical review highlights the challenging experiences of some of those trailblazers who participated in the AAN during the early days and made a mark for themselves in neurology. They helped pave the way for an increasing number of women who now serve in leadership roles-including back-to-back-to-back presidents-and make up 42% of the Academy's membership today...

Excessive fragmentary myoclonus (EFM) is a frequent finding during routine video-polysomnography (VPSG). We aimed to automatically measure the prevalence of EFM according to current American Academy of Sleep Medicine (AASM) criteria, and the fragmentary myoclonus index (FMI) in sleep stage N1, N2, N3, rapid eye movement (REM) sleep and wake in a large patient population. A total of 500 VPSG recordings of patients admitted to the Sleep Laboratory, Department of Neurology, Medical University of Innsbruck, Austria, between May 1, 2022 and February 28, 2023, were included...

Guidelines for brain death/death by neurologic criteria (BD/DNC) determination were revised to provide a consistent and updated approach to BD/DNC evaluation across all ages by the American Academy of Neurology, American Academy of Pediatrics, Child Neurology Society, and Society of Critical Care Medicine. This article is intended to complement the guidelines and highlight aspects relevant to the critical care community; the actual guidelines should be used to update hospital protocols and dictate clinical practice...

INTRODUCTION: In sub-Saharan Africa (SSA), the clinical and progressive diagnostic certainty of AIDS dementia is difficult to establish due to under-medicalization and delays in consultation and especially the diversity of etiologies of demented states. MATERIAL AND METHODS: We carried out a retrospective study of 196 patients hospitalized for dementia syndrome between 2016 and 2021 in the neurology department of the University Hospital of Conakry. The criteria labeled in this study are those retained by the DSM-IV and the classification of the American Academy of Neurology (AAN) developed in accordance with the WHO...

Penetrating lacerations to the hand are a common cause of nerve injury and can lead to debilitating pain and numbness in the distribution of the nerve affected. Owing to an overlap in the cutaneous innervation from different sensory nerves, clinically identifying the injured nerve can be difficult. We present a novel case of isolated injury to the palmar cutaneous nerve from a penetrating knife injury which was detected using 'comparison waveform' nerve conduction studies. Using this technique, we can isolate injuries to the palmar cutaneous branch of the median nerve (PCBmdn) from the median nerve, dorsal radial sensory nerve, and lateral antebrachial cutaneous nerve...

A rare but typically overlooked diagnosis in the orthopaedic surgery community is superior cluneal nerve (SCN) entrapment syndrome. The cluneal nerves function as purely sensory fibers, and the SCNs provide cutaneous innervation to the posterior parasacral, gluteal, and posterolateral thigh regions. When irritated, this syndrome can cause acute and chronic lower back pain and lower extremity symptoms. A 14-year-old adolescent girl presented to the clinic for an evaluation of pain in the right side of her lower back...

In collaboration with the American Academy of Pediatrics, Child Neurology Society, and Society for Critical Care Medicine, the American Academy of Neurology formulated an updated, evidence-informed consensus-based guideline for pediatric and adult brain death/death by neurologic criteria (BD/DNC) determination. In comparison with the prior guidelines, the revisions and additions in this guideline, which are summarized in this review, are intended to (1) ensure recommendations are conservative, yet practical, and emphasize circumstances in which BD/DNC determination should be delayed or deferred, so as to minimize the risk of a false-positive BD/DNC determination; and (2) provide guidance about aspects of BD/DNC determination that clinicians find challenging and/or controversial...

STUDY OBJECTIVES: Accurate diagnosis of isolated rapid eye movement (REM) sleep behavior disorder (iRBD) is crucial due to its injury potential and neurological prognosis. We aimed to analyze visual and automated REM sleep without atonia (RSWA) diagnostic thresholds applicable in varying clinical presentations in a contemporary cohort of iRBD patients using submentalis (SM) and individual bilateral flexor digitorum superficialis (FDS) and anterior tibialis (AT) electromyography limb recordings during polysomnography...

BACKGROUND AND OBJECTIVES: The purpose of this guideline is to update the 2010 American Academy of Neurology (AAN) brain death/death by neurologic criteria (BD/DNC) guideline for adults and the 2011 American Academy of Pediatrics, Child Neurology Society, and Society of Critical Care Medicine guideline for infants and children and to clarify the BD/DNC determination process by integrating guidance for adults and children into a single guideline. Updates in this guideline include guidance related to conducting the BD/DNC evaluation in the context of extracorporeal membrane oxygenation, targeted temperature management, and primary infratentorial injury...

STUDY OBJECTIVES: McLeod syndrome (MLS) is a very rare multisystemic neurodegenerative disease linked to mutations in the XK gene. It has cardiac, neurologic, and neuromuscular manifestations and shares similarities with Huntington's disease. The aim of this study was to evaluate sleep patterns of patients affected by MLS. METHODS: This retrospective case series of 4 males who underwent diagnostic polysomnography (mean age 53.8 ± 2.5 y) includes subjective and objective evaluation of sleep using the Epworth Sleepiness Scale (ESS), genetic tests, documentation of clinical course and features, and laboratory-based full-night attended video-polysomnography...
