The aim of the present study was to investigate the protective effects of miconazole on myelin sheaths following cerebral white matter damage (WMD) in premature infant rats. Sprague Dawley rats (3-days-old) were randomly divided into four groups (n=30 each) as follows: Sham surgery group, WMD model group, 10 mg/kg/day treatment group and 40 mg/kg/day treatment group. A cerebral white matter lesion model was created by ligating the right common carotid artery for 80 min. Treatment groups were administered with 10 or 40 mg/kg miconazole at 4-8 days following birth (early treatment group) or 5-11 days following birth (late treatment group)...

OBJECTIVE: Idiopathic Parkinson's disease (IPD) is the second most common neurodegenerative disorder, often complicated by dementia. Cardiovascular risk factors and spontaneous cerebral emboli (SCE) are strongly associated with Alzheimer's (AD) and vascular dementia (VaD). We measured SCE in the middle cerebral artery and arterial wall volume in the extracranial arteries in patients with IPD and controls, and explored the relationships with structural and physiological MRI brain neurovascular measures...

BACKGROUND: Migraine is considered as a risk factor for subclinical brain ischemic lesions, and right-to-left shunt (RLS) is more common among migraineurs. This cross-sectional study assessed the association of RLS with the increased prevalence of subclinical ischemic brain lesions in migraineurs. METHODS: We enrolled 334 migraineurs from a multicentre study from June 2015 to August 2016. Participants were all evaluated using contrast-enhanced transcranial Doppler, magnetic resonance imaging (MRI), and completed a questionnaire covering demographics, the main risk factors of vascular disease, and migraine status...

The ability of seeing with the mind's eye, the visual mental imagery, is peculiarly compromised in patients with representational neglect. Representational neglect affects the processing of the left side of a mental image and may selectively concern the ability to imagine places and/or objects. Right-brain damaged patients with representational neglect for places (RN+) lose the ability to imagine themselves within a familiar place and fail in transforming an egocentric representation of the environment into an allocentric one and vice-versa...

OBJECTIVE: To examine, first, whether the co-occurrence of executive dysfunction (ED) and poststroke depression (PSD) shows different associations with neuroimaging markers and the course of depression and executive function, and second, whether it is associated with a different course on other cognitive domains and quality of life. METHODS: The present study included 245 stroke patients (35.9% female, mean age 67.5 years (SD=11.9). All patients completed neuropsychological and neuropsychiatric assessment 3 months poststroke, which were repeated at 6-month and 12-month follow-up...

Theiler's murine encephalomyelitis (TME) is caused by the TME virus (TMEV) and represents an important animal model for multiple sclerosis (MS). Oligodendroglial apoptosis and reduced apoptotic elimination of encephalitogenic leukocytes seem to participate in autoimmune demyelination in MS. The present study quantified apoptotic cells in BeAn-TMEV-induced spinal cord white matter lesions at 14, 42, 98, and 196 days post infection (dpi) using immunostaining. Apoptotic cells were identified by transmission electron microscopy and double-immunofluorescence...

Analysis of microRNA (miR) expression in the central nervous system white matter of SJL mice infected with the BeAn strain of Theiler's murine encephalomyelitis virus (TMEV) revealed a significant reduction of miR-219, a critical regulator of myelin assembly and repair. Restoration of miR-219 expression by intranasal administration of a synthetic miR-219 mimic before disease onset ameliorates clinical disease, reduces neurogliosis, and partially recovers motor and sensorimotor function by negatively regulating proinflammatory cytokines and virus RNA replication...

BACKGROUND AND STUDY OBJECT: The Dominant Atrium (DA) is a crossroad of eloquent white matter bundles difficult to preserve with a standard "anatomical" approach. The aim of this work is to evaluate the results of a cohort of patients who underwent surgery with the aid of a purely functional MRI and DTI-based approach. MATERIALS AND METHODS: 43 patients suffering from lesions involving the DA have been included in the final cohort and studied in regards to quality of life (KPS); a special attention was lent on the incidence of new or worsening of preexisting neurological deficits, with a focus on motor, visual and speech disturbances after the surgical treatment...

PURPOSE: Rotavirus infection has recently been reported to be associated with seizures accompanied by leukoencephalopathy in newborns. We aimed to determine long-term outcomes and prognostic factors in newborns with neonatal seizures caused by rotavirus-associated leukoencephalopathy. METHODS: We retrospectively reviewed the records and brain magnetic resonance (MR) images of 32 patients who fulfilled the following criteria: (1) neonatal seizures, (2) distinctive symmetric cerebral white matter lesions on diffusion-weighted MR images (DWI), (3) rotavirus infection, (4) absence of a specific etiology of seizures, except for the aforementioned DWI lesions, and (5) Korean Bayley Scales of Infant Development II (K-BSID-II) assessment after 12 months of age...

MRI is the cornerstone of the diagnosis of multiple sclerosis (MS), and in recent years it was advocated for the follow up of the efficacy of the ever-growing number of disease modifying treatments (DMT). While in the clinical practice the most important biomarkers are still the T2 and T1 enhancing lesion burden, clinical studies are already utilising atrophy estimation. These measures cover a vast majority of MS pathology, namely the perivenular inflammation and gliosis in the white matter lesions as well as grey matter pathology...

A novel multi-organ disease that is fatal in early childhood was identified in three patients from two non-consanguineous families. These children were born asymptomatic but at the age of 2 months they manifested progressive multi-organ symptoms resembling no previously known disease. The main clinical features included progressive cerebropulmonary symptoms, malabsorption, progressive growth failure, recurrent infections, chronic haemolytic anaemia and transient liver dysfunction. In the affected children, neuropathology revealed increased angiomatosis-like leptomeningeal, cortical and superficial white matter vascularisation and congestion, vacuolar degeneration and myelin loss in white matter, as well as neuronal degeneration...

Antibodies against the myelin oligodendrocyte glycoprotein (MOG-Ab) can be detected in various pediatric acquired demyelinating syndromes (ADS). Here, we analyze the spectrum of neuroradiologic findings in children with MOG-Ab and a first demyelinating event. The cerebral and spinal MRI of 69 children with different ADS was assessed in regard to the distribution and characteristics of lesions. Children with acute disseminated encephalomyelitis (n = 36) or neuromyelitis optica spectrum disorder (n = 5) presented an imaging pattern characterized predominantly by poorly demarcated lesions with a wide supra- and infratentorial distribution...

Spastic paraplegia 35 (SPG35) is a recessive condition characterized by childhood onset, progressive course, complicated by dystonia, dysarthria, cognitive impairment, and epilepsy. Mutations in the FA2H gene have been described in several families, leading to the proposal of a single entity, named fatty acid hydrolase-associated neurodegeneration (FAHN). Several reports have described a polymorphic radiological picture with white matter lesions of various degrees and a distinct form of neurodegeneration with brain iron accumulation...

Both exfoliation syndrome (XFS) and exfoliation glaucoma (XFG) are associated with systemic vascular diseases and abnormalities. Though no uniform relationship between XFS/XFG and clinical systemic vascular diseases has been established across various populations, vascular dysfunction with or without clinically significant consequences has been repeatedly detected with both epidemiological and pathophysiological methods. Elevated plasma homocysteine, reduced cutaneous capillary flow reactions, damaged conduit artery dysfunction, impaired baroreflex sensitivity, parasympathetic cardiovascular neuropathy, and pathological heart rate variability indices have all been shown in XFS and XFG...

B-cell CLL/lymphoma 11B (Bcl11b) - a C2H2 zinc finger transcriptional factor - is known to regulate neuronal differentiation and function in the development of the central nervous system (CNS). Although its expression is reduced during oligodendrocyte (OLG) differentiation, its biological role in OLGs remains unknown. In this study, we found that the downregulation of Bcl11b gene expression in glial progenitor cells (GPCs) by lentivirus-mediated gene knockdown (KD) causes a reduction in cell proliferation with inhibited expression of stemness-related genes, while increasing the expression of cell cyclin regulator p21...

BACKGROUND: The corpus callosum index (CCI) can be easily and reliably obtained from conventional magnetic resonance imaging (MRI) and has been proposed as a possible marker of brain atrophy in MS. However, further validation of its correlation with volumetric measurements is still warranted. OBJECTIVE: To assess the correlation of the CCI with the corpus callosum volume (CCV), brain and lesion volumes, and level of disability in MS. METHODS: Cross-sectional, exploratory study including patients with relapsing-remitting MS...
