Mucopolysaccharidosis type II or Hunter syndrome (MPS II) is a genetic disease that can course with intellectual impairment and central nervous system (CNS) alterations. To date, no report has documented electroencephalogram (EEG) measures associated with CNS alterations, detected by imaging studies, and the history of seizures in patients with MPS II. Therefore, we decided to search this association. We included 9 patients with MPS II and performed imaging studies of the brain to detect the presence of cortico-subcortical atrophy, enlarged subarachnoid space and supratentorial ventricular size...

Very few cases of patients with myasthenia gravis (MG) who later developed amyotrophic lateral sclerosis (ALS) have been described, although some studies showed that significantly more cases than expected have ALS associated with a prior diagnosis of autoimmune diseases. Our aim was to investigate whether the association of ALS and MG was higher than expected in a population-based study and to describe the clinical features characterizing these patients. In Emilia Romagna Region of Italy, a prospective registry has been collecting all incident ALS cases since 1...

Multiple sclerosis (MS) spasticity is currently evaluated on the basis of neurological examinations such as Ashworth Scale (AS) and 0-10 NRS. Severity of spasticity is difficult to quantify. We investigated the use of real time elastography (RTHE) ultrasounds for evaluating objectively the muscle fibers status in MS spasticity patients and their changes after a new antispasticity treatment. Two studies were performed. In study A, 110 MS patients underwent a neurological evaluation based on the AS and RTHE. The RTHE images were scored with the new 1-5 muscle fibers rigidity imaging scale, here called MEMSs (Muscle Elastography Multiple Sclerosis Score)...

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by loss of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). Oxidative stress has been hypothesized to play a major role in the development of PD in various studies. This study assessed to investigate oxidative and anti-oxidative status in PD patients. We evaluated oxidant/antioxidant status by measuring serum malondialdehyde (MDA) levels, xanthine oxidase (XO) activities, and activities of antioxidant enzymes, namely, glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD)...

Observational studies suggested an association between hearing impairment and cognitive disorders. However, whether hearing impairment is an independent risk factor or a harbinger of Alzheimer's disease remains controversial. Our goal was to assess the association between hearing impairment (HI) and the risk of Alzheimer's disease (AD) by conducting a meta-analysis of prospective cohort studies. We comprehensively searched the PubMed, Embase, Web of Science and Cochrane Library databases on January 19, 2016 to incorporate all the prospective cohort studies meeting the inclusion criteria to perform a systematic review and meta-analysis...

Visual symptoms are frequently observed in posterior cortical atrophy compared to typical amnestic Alzheimer's disease (AD). We report the case of a patient with amnestic AD with long-lasting homonymous hemianopia. A 62-year-old woman, who was diagnosed in amnestic AD, complained of visual disturbance. She had left homonymous hemianopia in the perimetry test and left tactile extinction. Regardless of posture, retinotopically leftward error was observed on 21 cm line bisection test. Brain single photon emission computerized tomography (SPECT) showed bilateral temporoparietal hypoperfusion, which was more severe to the right than left side...

Neuropsychological examinations in myotonic dystrophy (DM) patients show a great variability of results from a condition of intellectual disability to the subtle cognitive impairments. It is unclear if different clusters of neuropsychological deficits appear in different phenotypes of DM, or if there are patients with no cognitive deficit at all. The aim of this study is to assess cognitive impairments among patients with different phenotypes of DM type 1 (DM1) and type 2 (DM2), and to potentially define cognitive clusters in these disorders...

As a biomarker of axonal injury, neurofilament light chain (NFL) in multiple system atrophy (MSA) patients and Parkinson's disease (PD) patients has been investigated by numerous studies. However, cerebrospinal fluid (CSF) NFL changes are conflicting in MSA patients relative to PD patients to date. Therefore, the current study was carried out to find out possible heterogeneity sources. Furthermore, "Neurofilament", "Neurofilament light chain" and "Multiple system atrophy" were employed to search "PubMed", "Springer" and "Medline" databases until August 2016 with standard mean difference (Std...

Recent several meta-analyses and certain case-control studies suggested that the Ras-like without CAAX 2 (RIT2) rs12456492 increased the risk of Parkinson's disease (PD) in Asian and Caucasian populations. However, as so far, the association between RIT2 rs12456492 and PD is still controversial. We investigated genetic association of RIT2 rs12456492 with PD susceptibility in a Han Chinese population of 1747 ethnic Han Chinese subjects comprising 884 PD patients and 863 healthy controls. The minor allele frequency (MAF) of G at the RIT2 rs12456492 was not significantly different between the cases and the controls...

Cerebrotendinous xanthomatosis (CTX) is a rare, genetically determined error of metabolism. The characteristic clinical symptoms are diarrhea, juvenile cataracts, tendon xanthomas and neuropsychiatric alterations. The aim of this study is to present a pair of identical adult twins with considerable differences in the severity of phenotype. With regards to neuropsychiatric symptoms, the predominant features were severe Parkinsonism and moderate cognitive dysfunctions in the more-affected individual, whereas these alterations in the less-affected patient were only very mild and mild, respectively...

Multiple sclerosis (MS) can impair cognitive functions even in the early stages. The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) battery is very short and highly sensitive and can be used to evaluate cognitive status in the disease. Several clinical trials have shown beneficial effects of disease-modifying drugs (DMDs) on long-term cognitive measures which may even reduce cognitive deficits in MS patients. Relapsing remitting MS patients using DMDs were enrolled in the study and monitored for 12 months...

Nowadays, the patients with deep brain stimulation (DBS) devices are restricted to undertake 1.5T magnetic resonance imaging (MRI) according to the guideline. Nevertheless, we conducted an experiment to test pathological change near the leads in different field-strength MRI. Twenty-four male New Zealand rabbits were assigned to Group 1 (G1, n = 6, 7.0T, DBS), Group 2 (G2, n = 6, 3.0T, DBS), Group 3 (G3, n = 6, 1.5T, DBS), and Group 4 (G4, n = 6, 1.5T, paracentesis). DBS leads were implanted in G1, G2 and G3, targeting left nucleus ventralis posterior thalami...

The study aimed to investigate the correlation between Parkinson's disease (PD) and serum levels of uric acid (UA), albumin and their interaction. A cross-sectional study was conducted to evaluate the relationship of serum UA, albumin with PD. A total of 96 PD patients and 108 healthy controls were recruited at Huai'an First People's Hospital, Nanjing Medical University. Baseline data included age, gender, body mass index (BMI), disease duration, Hoehn and Yahr scale (H&Y) stage, serum UA and albumin levels...

The study evaluated the efficacy of low-dose tacrolimus for treating Myasthenia Gravis (MG). Data were collected from 97 patients treated with low-dose tacrolimus from February 2011 to April 2015. Metabolic analysis was performed to determine more accurate tacrolimus dosing and patients were followed-up within clinic every 6 months for up to 4 years. The myasthenia gravis-specific activities of daily living scale was used to assess MG symptoms and their effects on patients' daily activities. All side effects and adverse reactions were thoroughly documented...
