AIMS: While vascular pathology is a common feature of a range of neurodegenerative diseases, we hypothesised that vascular changes occur in association with normal ageing. Therefore we aimed to characterise age-associated changes in the blood brain barrier (BBB) in human and mouse cohorts. METHODS: Immunohistochemistry and Evans Blue assays were used to characterise BBB dysfunction (tight junction protein expression and serum plasma protein accumulation), vascular pathology (pericyte loss and vascular density) and glial pathology (astrocyte and microglial density) in ageing neurological control human pre-frontal cortex (a total of 23 cases from 5 age groups representing the spectrum of young adult to old age: 20-30yrs, 31-45yrs, 46-60yrs, 61-75yrs and 75+) and C57BL/6 mice (3 month, 12 month, 18 month and 24 month, n=5/6 per group)...

Eyelid retraction, has received limited attention and it has passively been interpreted as the result of an overactive levator palpebrae superioris muscle secondary to midbrain injury. However, eyelid retractions can occur in other neurological diseases, not directly related with the midbrain. We report three patients who developed eyelid retraction. One patient had a bilateral eyelid retraction, related with Creutzfeldt-Jakob disease (CJD). Another patient had a unilateral right eyelid retraction associated with a thalamic-mesencephalic infarct...

Present report describes a 46 year old male patient with a diagnosis of major depression who developed tardive dyskinesia during bupropion therapy. Our patient had no history of neuroleptic use and his laboratory and neurologic examinations were normal. He had no family history of neurologic diseases. Although bupropion induced dyskinesia has been previously reported in the literature, it is rare and our case is the first case regarding tardive dyskinesia.

In 2011, heterozygous mutations in the ANKRD11 gene were identified in patients with KBG syndrome. Since then, 100 cases have been described with the expansion of the clinical phenotype. Here we present 18 KBG affected individuals from 13 unrelated families, 16 with pathogenic mutations in the ANKRD11 gene. Consistent features included intellectual disability, macrodontia, and the characteristic broad forehead with hypertelorism, and a prominent nasal bridge. Common features included hand anomalies, cryptorchidism, and a large number of palate abnormalities...

HIV-associated neurocognitive disorder (HAND) often complicates HIV infection despite combination antiretroviral therapy (ART) and may be influenced by host genomics. We performed a genome-wide association study (GWAS) of HAND in 1,050 CNS HIV Anti-Retroviral Therapy Effects Research (CHARTER) Study participants. All participants underwent standardized, comprehensive neurocognitive, and neuromedical assessments to determine if they had cognitive impairment as assessed by the Global Deficit Score (GDS), and individuals with comorbidities that could confound diagnosis of HAND were excluded...

Acute cerebellitis (AC) is a rare inflammatory syndrome presenting as cerebellar dysfunction, seen more frequently in children. AC can have a variable course with features of cerebellar dysfunction, raised intracranial pressure and neurological deficits, and can sometimes even be potentially fatal due to complications such as obstructive hydrocephalus and brainstem compression, warranting surgical intervention. We report a case of a 12-year-old boy who presented with raised intracranial pressure and ataxia...

BACKGROUND: Although migraine is one of the most investigated neurologic disorders, we do not have a perfect neuroimaging biomarker for its pathophysiology. One option to improve our knowledge is to study resting-state functional connectivity in and out of headache pain. However, our understanding of the functional connectivity changes during spontaneous migraine attack is partial and incomplete. CASE PRESENTATION: Using resting-state functional magnetic resonance imaging we assessed a 24-year old woman affected by migraine without aura at two different times: during a spontaneous migraine attack and in interictal phase...

BACKGROUND: Known predictors of neurosyphilis were mainly drawn from human immunodeficiency virus (HIV)-infected syphilis patients, which may not be applicable to HIV-negative populations as they have different characteristics, particularly those with neurological symptoms. This study aimed to identify novel predictors of HIV-negative symptomatic neurosyphilis (S-NS). METHODS: From June 2005 to June 2015, 370 HIV-negative syphilis patients with neurological symptoms were recruited, consisting of 191 S-NS patients (including 123 confirmed neurosyphilis and 68 probable neurosyphilis patients) and 179 syphilis/non-neurosyphilis (N-NS) patients...

RATIONALE: Peripheral neurological complications in primary Sjögren's syndrome (pSS) seem the most common, however the involvement of central nervous system (CNS) remains unclear. While abnormalities in pSS revealed by brain magnetic resonance imaging (MRI) are usually small discrete hyperintense areas in the white matter on T2-FLAIR weighted MRI, massive brain lesions have been rarely reported, particularly in bilateral basal ganglia. PATIENT CONCERNS: A 51-year-old woman exhibited dizziness, slurred speech and hemiplegia as a manifestation of pSS...

Approximately half of the human brain is composed of white matter (WM), a specialized tissue housing the axonal projection of neurons and their necessary supporting glial cells. Axons course long distances from their parent soma, have a delicate structure, large surface area and in many cases are dependent upon a uniquely close morphological arrangement with myelinating oligodendrocyte partners; all factors that may predispose them to injury and disease. WM damage is central to a range of well-characterized disorders including multiple sclerosis and spinal cord injury and is also makes a significant contribution to disorders often considered to be largely focused in gray matter; for example, in stroke where ~49% of injury by volume is located in WM...

A 49-year-old man with ischemic cardiomyopathy and tricuspid regurgitation underwent a DuraHeart implantation and tricuspid annuloplasty for bridge-to-heart transplantation. On postoperative day 393, the magnetic levitation system suddenly broke down, and the pump system went into hydrodynamic bearing rotation (HD) mode without causing relevant symptoms. The controller was exchanged with one that adapted to the HD mode. No significant hemodynamic changes or indications of hemolysis were observed. On postoperative day 982, the pump temporarily stopped nine times...

In recent years, medical imaging with hybrid techniques has widely accepted and employed in clinical routine. PET/MRI offers significant advantages, including excellent contrast and resolution and reduced ionizing radiation, as compared to well-established PET/CT. Therefore, PET/MRI is a promising modality for oncologic imaging of some regions, such as brain, head and neck, liver and pelvis. This article set out to analyze clinical conditions that could benefit from PET/MRI imaging based on our caseload. The potential of PET/MRI to become the imaging modality of choice for assessment of neurologic and oncologic conditions associated with soft tissues is highlighted...

This article discusses the peculiar conditions that favoured the unexpected introduction of Zika virus into the poorest northeastern region of Brazil in 2015, its speed of transmission to other Brazilian states, other Latin American countries and other regions, and the severity of related neurological disorders in newborns and adults. Contrasting with evidence that Zika had so far caused only mild cases in humans in the last six decades, the epidemiological scenario of this outbreak in Brazil indicates dramatic health effects: in 2015, an increase of 20-fold in notified cases of microcephaly and/or central nervous system (CNS) alterations suggestive of Zika congenital infection, followed by an exponential increase in 2016, with 2366 cumulative cases confirmed in the country by the end of December 2016...
