We describe a case of Parry Romberg syndrome/en coupe de sabre in a woman whose disease started as seizures at age 8 but was diagnosed at the age 39. During these 31 years she got married, completed a first degree at university, had two successful pregnancies and has been gainfully employed. The features of generalized tonic-clonic seizures, autoimmune abnormalities, ocular abnormalities, morphea en coup de sabre and brain imaging abnormalities were present. Areas of parietal lobe cerebral calcification were encountered on the computed tomographic scan and bilateral periventricular white matter changes on the magnetic resonance imaging with frontal, temporal and parietal lobe brain atrophy ipsilateral to the facial hemiatrophy...

OBJECTIVE: The INTERACT2 trial demonstrated beneficial effects of early intensive blood pressure (BP) lowering in intracerebral hemorrhage (ICH). However, concerns persist over harms associated with the treatment, particularly in patients with cerebral small vessel disease (CSVD) (ie white matter lesions [WML], lacunes and atrophy) and renal failure. We determined associations of CSVD, and renal failure, on outcomes in INTERACT2 participants. DESIGN AND METHOD: There were 2069/2839 patients with baseline brain CT (< 6hr ICH onset)...

Carbon monoxide (CO) poisoning affects 50,000 people a year in the United States. The clinical presentation runs a spectrum, ranging from headache and dizziness to coma and death, with a mortality rate ranging from 1-3%. A significant number of patients who survive CO poisoning suffer from long term neurologic and affective sequelae. The neurologic deficits do not necessarily correlate with blood CO levels, but likely result from the pleiotropic effects of CO on cellular mitochondrial respiration, cellular energy utilization, inflammation and free radical generation, especially in the brain and heart...

PURPOSE OF REVIEW: Spinocerebellar ataxia type 12 (SCA12) is a rare autosomal dominant neurodegenerative disease characterized by tremor, gait abnormalities, and neuropsychiatric syndromes. The location of the causative CAG/CTG expansion mutation in PPP2R2B, a gene encoding regulatory units of the protein phosphatase 2A, may provide unique insights into the pathogenesis of neurodegeneration. RECENT FINDINGS: The first neuropathological examination of a brain from an SCA12 patient revealed both cerebellar and cerebral cortical atrophy, with a noted loss of Purkinje cells and no evidence of polyglutamine aggregates...

Cerebral folate deficiency due to folate receptor 1 gene (FOLR1) mutations is an autosomal recessive disorder resulting from a brain-specific folate transport defect. It is characterized by late infantile onset, severe psychomotor regression, epilepsy, and leukodystrophy. We describe a consanguineous girl exhibiting severe developmental regression, intractable epilepsy, polyneuropathy, and profound hypomyelination with cortical involvement. Magnetic resonance imaging showed cortical disturbances in addition to profound hypomyelination and cerebellar atrophy...

INTRODUCTION: Mutations of SLC35A2 that encodes Golgi-localized Uridine diphosphate (UDP)-galactose transporter at Xp11.23 lead to congenital disorders of glycosylation (CDG). Although patients with CDG generally have diverse systemic symptoms, patients with a SLC35A2 mutation manifest predominantly disorders of the central nervous system (CNS). CASE REPORT: A female infant aged 12months was referred to our center because of intractable seizures. The patient was born with birth weight of 3228g after 40weeks of unremarkable gestation...

Although East Asia harbors the largest number of aging adults in the world, there is currently little data clarifying the longitudinal brain-cognition relationships in this group. Here, we report structural MRI and neuropsychological findings from relatively healthy Chinese older adults of the Singapore-Longitudinal Aging Brain Study cohort over 8 years of follow up (n = 111, mean age = 67.1 years, range = 56.1-83.1 years at baseline). Aging-related change in structural volume was observed, with total cerebral atrophy at -0...

BACKGROUND: Triple A syndrome (MIM #231550) is associated with mutations in the AAAS gene. However, about 30% of patients with triple A syndrome symptoms but an unresolved diagnosis do not harbour mutations in AAAS. OBJECTIVE: Search for novel genetic defects in families with a triple A-like phenotype in whom AAAS mutations are not detected. METHODS: Genome-wide linkage analysis, whole-exome sequencing and functional analyses were used to discover and verify a novel genetic defect in two families with achalasia, alacrima, myopathy and further symptoms...

BACKGROUND AND PURPOSE: Cerebral microbleeds (CMBs), cortical superficial siderosis, white matter lesions (WML), and cerebral atrophy may signify greater bleeding risk particularly in patients in whom anticoagulation is to be considered. We investigated their prevalence and associations with stroke type in patients with stroke and atrial fibrillation (AF). MATERIALS AND METHODS: Cross-sectional sample, Monash Medical Centre (Melbourne, Australia) between 2010 and 2013, with brain MRI...

BACKGROUND: Refractory status epilepticus is often treated with third-line therapy, such as pentobarbital coma. However, its use is limited by side effects. Recognizing and preventing major and minor adverse effects of prolonged pentobarbital coma may increase good outcomes. This study retrospectively reviewed direct and indirect medical and surgical pentobarbital coma. METHODS: Retrospective chart review of all patients with refractory status epilepticus treated with pentobarbital over a 1 year period at a large tertiary care center...

As human life expectancy rises, the aged population will increase. Aging is accompanied by changes in tissue structure, often resulting in functional decline. For example, aging within blood vessels contributes to a decrease in blood flow to important organs, potentially leading to organ atrophy and loss of function. In the central nervous system, cerebral vascular aging can lead to loss of the integrity of the blood-brain barrier, eventually resulting in cognitive and sensorimotor decline. One of the major of types of cognitive dysfunction due to chronic cerebral hypoperfusion is vascular cognitive impairment and dementia (VCID)...

AIM: We investigated the characteristics of elderly medical patients with white matter hyperintensities on magnetic resonance imaging. METHODS: A total of 213 patients (123 men and 90 women; mean age 74.8 years) reported their history of hypertension, diabetes, dyslipidemia, previous stroke, coronary heart disease and chronic kidney disease (CKD). All patients completed the Mini-Mental State Examination and Geriatric Depression Scale. White matter hyperintensities were evaluated for the periventricular region, basal ganglia (BGH), deep white matter and infratentorial region, and brain atrophy was calculated as bicaudate ratios...

OBJECTIVE: Corticospinal tract damage is responsible for motor function impairment after stroke. However, many processes seem to induce muscle damage, which may limit rehabilitation achievement. To achieve a systematic literature review of human muscular modifications due to post-strike hemiplegia. This review considers structural (histological, biochemical) and physiological modifications and their functional consequences over 1 year after stroke. MATERIAL/PATIENTS AND METHODS: Literature search on PubMed, Embase and Cochrane databases for papers published before February 2016 combining the following keywords cerebral stroke, hemiplegic, atrophy, muscle structure, paresis, skeletal muscle fiber type, motor unit, oxidative stress, strength, motor control led to select forty articles...

OBJECTIVE: Botulinum toxin is one of the treatments available to treat spasticity in patients with cerebral palsy (CP) from 2 years of age. The long-term action of the toxin on the neuromuscular junction (NMJ) and muscle structure is still unknown. We formulated the hypothesis that repeated injections of botulinum toxin could modify muscle structure. The main aim of our 3-year monocentric descriptive study is to evaluate the long-term effect of repeated injections of botulinum toxin on the muscle and the neuromuscular junction in patients with CP...

BACKGROUND: Imaging studies have revealed widespread neurodegeneration in Parkinson's disease (PD), but only a few considered the issue of asymmetrical clinical presentations. OBJECTIVE: To investigate if the side of onset influences the pattern of gray matter (GM) atrophy in PD. METHODS: Sixty patients (57.87 ± 10.27 years) diagnosed with idiopathic PD according to the U.K. Brain Bank criteria, 26 with right-sided disease onset (RDO) and 34 with left-sided disease onset (LDO), were compared to 80 healthy controls (HC) (57...

BACKGROUND AND PURPOSE: Small vessel disease is a major cause of neurocognitive dysfunction in the elderly. Small vessel disease may manifest as white matter hyperintensities, lacunar infarcts, cerebral microbleeds, and atrophy, all of which are visible on conventional MR imaging or as microstructural changes determined by diffusion tensor imaging. This study investigated whether microstructural integrity is associated with neurocognitive dysfunction in older individuals, irrespective of the conventional features of small vessel disease...

The Aicardi-Goutières syndrome (AGS) was first described in 1984, and over the following years was defined by the clinical and radiological features of an early onset, severe, neurologic disorder with intracranial calcification, leukoencephalopathy, and cerebral atrophy, usually associated with a cerebrospinal fluid (CSF) pleocytosis and elevated CSF interferon α activity. It is now recognized that mutations in any of the following seven genes may result in the classical AGS phenotype: TREX1 (AGS1), RNASEH2A (AGS2), RNASEH2B (AGS3), RNASEH2C (AGS4), SAMHD1 (AGS5), ADAR1 (AGS6), and IFIH1 (AGS7)...
