Abstract Objectives Using recent optimized electrodiagnostic criteria sets, we primarily aimed at verifying the accuracy of the initial electrophysiological test in very early Guillain-Barre syndrome (VEGBS), ≤ 4 days of onset, compared with the results of serial electrophysiology. Our secondary objective was to correlate early electrophysiological results with sonographic nerve changes. Methods This is a retrospective study based on consecutive VEGBS patients admitted to the hospital. Each pati...

Summary Background Genome-wide association studies (GWAS) in Parkinson's disease have increased the scope of biological knowledge about the disease over the past decade. We aimed to use the largest aggregate of GWAS data to identify novel risk loci and gain further insight into the causes of Parkinson's disease. Methods We did a meta-analysis of 17 datasets from Parkinson's disease GWAS available from European ancestry samples to nominate novel loci for disease risk. These datasets incorporated ...

Parkinson’s disease (PD), with its characteristic loss of nigrostriatal dopaminergic neurons and deposition of α-synuclein in neurons, is often considered a neuronal disorder. However, in recent years substantial evidence has emerged to implicate glial cell types, such as astrocytes and microglia. In this study, we used stratified LD score regression and expression-weighted cell-type enrichment together with several brain-related and cell-type-specific genomic annotations to connect human genomi...

C-reactive protein (CRP) is a biomarker of systemic inflammation that has been linked to accelerated decline in walking speed in older adults. The aim of the present study was to compare the CRP levels of PD patients with vs patients without freezing of gait (FOG). Patients and controls participating in the COPPADIS-2015 study that performed blood extraction for determining molecular serum biomarkers were included. Patients with FOG were identified as those with a score of 1 or greater on item-3...

Spinocerebellar ataxia type 3 (SCA3) is a devastating multisystemic neurodegenerative disease for which targeted molecular therapies are coming into reach (e.g. antisense oligonucleotides). To pave the way for upcoming translational trials, easily accessible biomarkers in SCA3 are needed, particularly for subjects at the preataxic stage and cross-validated also in animal models. We hypothesised that serum neurofilaments might serve as blood biomarkers of disease progression in both human SCA3 an...

Adolescent-onset spastic ataxia is a proposed novel phenotype in compound heterozygous carriers of an intronic mutation (c.1909 + 22G > A) in the POLR3A gene. Here, we present ten new cases of POLR3A-related spastic ataxia and discuss the genetic, clinical and imaging findings. Patients belonged to six pedigrees with hereditary spastic paraplegia or cerebellar ataxia of unknown origin. All affected subjects presented with compound heterozygous variants, comprising c.1909 + 22G > A in combination...

BACKGROUND: Spinocerebellar ataxias are rare dominantly inherited neurodegenerative diseases that lead to severe disability and premature death. OBJECTIVE: To quantify the impact of disease progression measured by the Scale for the Assessment and Rating of Ataxia on survival, and to identify different profiles of disease progression and survival. METHODS: Four hundred sixty-two spinocerebellar ataxia patients from the EUROSCA prospective cohort study, suffering from spinocerebellar ataxia type 1...
