It has been argued that Adolf Hitler (1889 - 1945) had Parkinson's disease. He also experienced several gastrointestinal symptoms, for which various explanations have been sought, both contemporaneously and by later authors. In this Historical Note, a possible relationship between Hitler's Parkinson's disease and his gastrointestinal symptoms is explored. Specifically, we posit the hypothesis that Hitler may have suffered from small-intestinal bacterial overgrowth (SIBO), thus providing an early example of SIBO occurring as a prodromal Parkinson's disease symptom...

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic represents one of the most challenging issues that have recently influenced everyday life in countries all over the world. Understanding the risk of this disease is of high importance in patients with multiple sclerosis (MS) as they represent a vulnerable population through their treatment with disease-modifying therapies (DMTs). Infective episodes may trigger relapses and lead to deterioration of the health condition...

Introduction 　　Clinical prediction rule (CPR) using decision tree analysis is able to show the branching of the variables under consideration in a clear, hierarchical manner, including specific reference values, which can be used as classifiers in clinical practice. However, CPR developed by decision tree analysis for predicting the degree of independent living of patients with thoracic spinal cord injury (SCI) are few. The purpose of this study was to develop a simplified CPR for prognosticating dependent daily living in patients with thoracic SCI...

INTRODUCTION: The definite diagnosis of neurosarcoidosis is challenging since it requires a compatible histology of the nervous system. When neurosarcoidosis is suspected, other systemic manifestations are investigated to confirm the diagnosis. A minor salivary gland biopsy (MSGB) is often performed since it is minimally invasive. The objective of the present study was to assess its performance for the diagnosis of neurosarcoidosis. METHODS: A retrospective single-center study included patients who underwent a MSGB in a tertiary neurological university hospital (Lyon, France) between 2015 and 2018...

BACKGROUND: Acute transverse myelitis (ATM) is a rare neurological disorder in adults characterized by localized inflammation of gray and white matter in one or more contiguous spinal cord segments in the absence of a compressive injury. Several reports have connected the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to the pathophysiology of ATM. SUMMARY: Direct invasion of the spinal cord, cytokine storm, or an autoimmune response are the possible pathways by which the SARS-CoV-2 virus can affect the spinal cord and lead to ATM...

BACKGROUND: We investigated the longevity of COVID-associated brain fog in patients who have survived the COVID-19. METHODS: This was a follow-up study of 2,696 adult patients with COVID-19 from our previous study (doi: 10.1002/jmv.27404). We selected every other patient in our database. The follow-up data were collected during a phone call to the participants in January-February 2022 (11 months after the initial study): concentration difficulty and the patient's self-declared status in their ability to concentrate...

Mutations in the neurofilament polypetide light chain (NEFL) gene account for <1 % of all forms of Charcot-Marie-Tooth (CMT) diseases, and present with different phenotypes, including demyelinating, axonal and intermediate neuropathies and with diverse pattern of transmission, with dominant and recessive inheritance being described. Here we present clinical and molecular data in two new unrelated Italian families, affected with CMT. We studied fifteen subjects (11 women, 4 men), age range 23-62 year. Onset of symptoms was mainly in childhood, with running/walking difficulties; some patients were pauci-asymptomatic; almost all shared variably distributed features of absent/reduced deep tendon reflexes, impaired gait, reduced sensation and distal weakness in the legs...

BACKGROUND: Futile reperfusion (FR) is becoming an urgent issue for acute ischemic stroke patients who underwent endovascular treatment (EVT). Although the recanalization rate has improved after EVT, it is far from translating to increased tissue reperfusion and functional independence. SUMMARY: Many underlying mechanisms including the "no-reflow" phenomenon, poor collateral flow, venous dysfunction, and inflammation were proposed, but the pathophysiology of FR is still unclear...

The impact of the collaboration between photographer Eadweard Muybridge and neurologist Francis Dercum is detailed within the context of a photographic study of an artificially induced psychogenic non-epileptic seizure. Their contribution served as inspiration to other contemporary European neurologists and photographers to use motion photography to further understand psychogenic neurological disorders, such as seizures.

A solitary pontine lesion (SPL) is a single brainstem lesion on the trigeminal nerve pathway without any other central nervous system lesion. This research aimed to investigate the demographic and clinical features of nonpainful TNO patients with SPL and identify the most frequently affected anatomical areas using lesion mapping techniques. Demographic and clinical features were retrospectively reviewed from the patients' charts. Brain lesions were mapped using MRIcroGL software. The study included 6 patients (three females and three males) with an SPL...

BACKGROUND: This review article integrates findings from published behavioural and neuroimaging studies of impulsive-compulsive behaviours (ICBs) in Parkinson's disease, with the aim of identifying the basic correlates of these problematic and distressing behaviours. The underlying premise is that for any feature to be a reliable marker of ICBs, it should be evident across multiple levels of analyses. When changes are evident only at one level, but not in the others, their reliability as indicators of ICBs should be questioned...

BACKGROUND: The no-reflow phenomenon refers to a failure to restore normal cerebral microcirculation despite brain large artery recanalization after acute ischemic stroke, which was observed over 50 years ago. SUMMARY: Different mechanisms contributing to no-reflow extend across the endovascular, vascular wall, and extravascular factors. There are some clinical tools to evaluate cerebral microvascular hemodynamics and represent biomarkers of the no-reflow phenomenon...

INTRODUCTION: MRI activity is less frequent among secondary progressive multiple sclerosis (SPMS) patients. In the current study, we aimed to identify SPMS patients with higher radiological disease activity (RDA) and determine their clinical characteristics. METHODS: We evaluated the occurrence of RDA in SPMS patients followed at the Sheba Multiple Sclerosis Center between January 1, 2015, and December 31, 2020. All patients underwent brain and spinal cord MRI examinations as a routine follow-up unrelated to clinical disease activity...

INTRODUCTION: Brain arteriovenous malformations (BAVMs) are high-flow intracranial vascular malformations characterized by the direct connection of arteries to veins without an intervening capillary bed. They are one of the main causes of intracranial hemorrhage and epilepsy, although morbidity is low. Angiogenesis, heredity, inflammation, and arteriovenous malformation syndromes play important roles in BAVM formation. Animal experiments and previous studies have confirmed that NOTCH4 may be associated with BAVM development...

INTRODUCTION: Constipation is a common nonmotor symptom of Parkinson's disease (PD) and has been reported to increase the risk of developing PD. However, previous studies have yielded conflicting results. Understanding this correlation may promote early diagnosis and treatment of PD, which could help patients improve their quality of life. This study aimed to investigate the association between constipation and PD onset. METHODS: The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-analyses of Observational Studies in Epidemiology (MOOSE) guidelines...

INTRODUCTION: Working memory (WM) refers to the temporary storage and manipulation of information. Short-term memory storage can be divided into separate subsystems for verbal information and visual information. We explored the capacity of visual WM in patients with temporal lobe glioma. METHODS: In this study, we assessed 30 patients with temporal lobe glioma and 30 healthy controls (HCs) using a method that combined memory tests with visual WM tasks (digital span task, spatial capacity N-back task, and emotional N-back task)...
