PURPOSE: For a diagnosis of Rasmussen syndrome (RS), clinical course together with electroencephalography (EEG) and magnetic resonance imaging (MRI) findings are considered important, but there are few reports on functional neuroimaging. This study investigated cerebral blood flow (CBF)-single photon emission computed tomography (SPECT), central benzodiazepine receptor (BZR)-SPECT, and fluorine-18 fluorodeoxy glucose-positron emission tomography (FDG-PET) in RS patients, and correlated neuroimaging results with MRI and pathological findings...

Posterior reversible encephalopathy syndrome (PRES) is a rare but well-described syndrome associated with a high morbidity and a substantial mortality. We present an illustrative case of an HIV-infected but virologically suppressed patient who complained of visual impairment accompanied by severe headache and epileptic seizures. The cerebral CT scan and the follow-up cranial MRI confirmed the diagnosis of PRES. Unlike the cases of HIV-infected patients with PRES published so far, our patient suffered neither from advanced immunodeficiency nor from opportunistic infection or from any other evident predisposing factor...

Dementia with Lewy bodies (DLB) is the most common cause of dementia after Alzheimer disease. It is often underdiagnosed because of the overlapping with Alzheimer disease symptoms. We report the F-FDG and F-florbetapir dynamic PET images (early and delay phases) of an 83-year-old woman with cognitive impairment associated with visual hallucinations and parkinsonism due to probable DLB. This image highlights that the early phases of F-florbetapir may reflect regional cerebral perfusion with a pattern very similar to that of regional glucose metabolism in DLB...

The perception of music can be impaired after a stroke. This dysfunction is called amusia and amusia patients often also show deficits in visual abilities, language, memory, learning, and attention. The current study investigated whether deficits in music perception are selective for musical input or generalize to other perceptual abilities. Additionally, we tested the hypothesis that deficits in working memory or attention account for impairments in music perception. Twenty stroke patients with small infarctions in the supply area of the middle cerebral artery were investigated with tests for music and visual perception, categorization, neglect, working memory and attention...

Ulegyria refers to scarring of the cerebral cortex usually arising from perinatal ischaemia. The scarring has a specific configuration in which small atrophic circumvolutions at the bottom of a sulcus underlie an intact spared gyral apex. This disconnection of overlying cortex may allow an "epileptogenic" island of cortex to generate seizures. Ulegyria is often associated with epilepsy and developmental delay, however, the syndromic association of visual impairment with epilepsy due to occipital ulegyria may not be recognised as a specific entity...

Cerebral small vessel disease (CSVD) occurs often in memory clinic patients. Apart from cognitive deficits, these patients can express physical decline, which predicts adverse health outcomes. In this study, we investigated the cooccurrence of clinically relevant impairments in physical performance and CSVD in memory clinic patients. We included 131 patients with vascular brain injury, mild cognitive impairment or Alzheimer disease with available 3T MRI and physical performance scores. CSVD was visually rated according to 3 subtypes and as a total burden score, composed of the presence of white matter hyperintensities (WMH), lacunar infarcts (LI), and cerebral microbleeds (MB)...

OBJECTIVE Direct brain compression and secondary injury due to increased intracranial pressure are believed to be the pathognomic causes of a grave outcome in acute subdural hemorrhage (aSDH). However, ischemic damage from aSDH has received limited attention. The authors hypothesized that cerebral microcirculation is altered after aSDH. Direct visualization of microcirculation was conducted in a novel rat model. METHODS A craniectomy was performed on each of the 18 experimental adult Wistar rats, followed by superfusion of autologous arterial blood onto the cortical surface...

PURPOSE: Hemiplegic cerebral palsy patient may present a shorten leg on the hemiplegic side that afflicts negatively the kinematic of the uninvolved limb. Thus, the aim of this study was to investigate the modification of gait kinematic after epiphysiodesis for limb equalization and secondary to verify the prediction of correction. METHODS: Skeletally immature hemiplegic patients with a minimum limb leg discrepancy (LLD) of 2.5 cm were treated with epiphysiodesis of the unaffected knee and clinically evaluated with Edinburgh visual gait score (EVGS)...

INTRODUCTION: Preterm and very low birthweight infants are at increased risk for neurodevelopmental disorders, including cerebral palsy, sensory impairment and intellectual disability. Several early intervention approaches have been designed in the hope of optimising neurological development in this context. It seems important that the intervention takes into account parental mental health, focuses on parent-child interactions and lasts sufficiently long. This study aims to evaluate the effects of a stimulation programme administered by parents until 6 months post-term on motor and neurophysiological development of infants born preterm...

Perinatal stroke is the leading cause of hemiparetic cerebral palsy (CP), resulting in life-long disability. In this study, we examined the relationship between robotic upper extremity motor impairment and corticospinal tract (CST) diffusion properties. Thirty-three children with unilateral perinatal ischemic stroke (17 arterial, 16 venous) and hemiparesis were recruited from a population-based research cohort. Bilateral CSTs were defined using diffusion tensor imaging (DTI) and four diffusion metrics were quantified: fractional anisotropy (FA), mean (MD), radial (RD), and axial (AD) diffusivities...

BACKGROUND: Cerebrospinal fluid (CSF) biomarker studies have shown variable accuracy for diagnosis of Alzheimer's disease (AD); therefore, internal validation is recommended. OBJECTIVE: To investigate the correlation between CSF biomarkers and cerebral 18-Florbetapir positron emission tomography (Amyloid-PET) and calculate their sensitivity and specificity to obtain the optimal clinical cut-off points to diagnose the etiology of cognitive impairment. METHODS: We performed Amyloid-PET scans and CSF biomarker levels analyses in 68 subjects (50 with mild cognitive impairment, 11 with AD dementia, and 7 with non-AD dementia)...

The childhood condition of visual difficulties caused by brain damage, commonly termed cortical or cerebral visual impairment (CVI), is well established but has no internationally accepted definition. Clarification of its core features is required to advance research and clinical practice. This systematic review aimed to identify the definitions of childhood CVI in the original scientific literature to describe and critically appraise a consensual definition of the condition. MEDLINE, EMBASE, PsychINFO, CINAHL and AMED databases were searched in January 2017...

The central nervous system, specifically the brain, is implicated in the development of exertional fatigue under a hot environment. Diverse neuroimaging techniques have been used to visualize the brain activity during or after exercise. Notably, the use of magnetic resonance imaging (MRI) has become prevalent due to its excellent spatial resolution and versatility. This review evaluates the significance and limitations of various brain MRI techniques in exercise studies - brain volumetric analysis, functional MRI, functional connectivity MRI and arterial spin labelling...

BACKGROUND: Cerebral palsy (CP) is a disorder of motor function often accompanied by cognitive impairment. There is a paucity of research focused on cognition in dyskinetic CP and on the potential effect of related factors. AIM: To describe the cognitive profile in dyskinetic CP and to assess its relationship with motor function and associated impairments. METHOD: Fifty-two subjects with dyskinetic CP (28 males, mean age 24 y 10 mo, SD 13 y) and 52 typically-developing controls (age- and gender-matched) completed a comprehensive neuropsychological assessment...
