BACKGROUND To date there are no biomarkers with proven reliability as a measure of disease burden in amyotrophic lateral sclerosis (ALS). The aim of our study is to assess the neurofilament light chain (NFL) in cerebrospinal fluid (CSF) samples as a measure of disease activity and progression in ALS. METHODS Thirty-seven consecutive patients with ALS, 25(More)
Urate is a natural antioxidant, and high serum urate levels could be protective against the development of amyotrophic lateral sclerosis (ALS). To determine if serum urate concentrations were lower in ALS patients than in healthy controls, we compared serum urate levels in 132 ALS patients and 337 age/sex-matched controls. Median urate levels were lower in(More)
The aim of this study is to investigate the frequency and the clinical correlations of pseudobulbar affect (PBA) in a population-based incident cohort of ALS patients. Incident ALS cases, diagnosed in 2011 and 2012, according to El Escorial criteria were enrolled from a prospective population-based registry in Apulia, Southern Italy. Neurological status was(More)
Hereditary spastic paraplegia (HSP) includes a group of diseases characterized by progressive spastic weakness of the lower limbs (pure forms) with possible additional signs (complicated forms). The SPG10 form is due to alteration in the kinesin1A gene (KIF5A) that encodes the neuronal kinesin heavy chain, a protein required for the anterograde axonal(More)
BACKGROUND AND PURPOSE To evaluate whether cerebrospinal fluid (CSF) neurofilament light chain (NFL) levels could predict the time to generalization (TTG) in amyotrophic lateral sclerosis (ALS). METHODS Cerebrospinal fluid NFL levels of 37 cases of sporadic ALS were measured and the time of symptom spreading from spinal or bulbar localization to both(More)
The pathophysiological mechanism of the pain in ALS is still unclear. The aim of the study was to evaluate the laser evoked potentials (LEPs) in ALS patients in relation to their clinical features. Twenty-four ALS patients were selected. Pain features were assessed and their intensity was measured by a 0-10 VAS. LEPs were recorded in all patients and in 23(More)
BACKGROUND N -acetylaspartate (NAA) level is a biomarker of functional integrity and vitality in neurons. In vivo multisection proton ((1)H)-magnetic resonance spectroscopy studies indicate that NAA level decreases in specific cortical brain areas of patients with amyotrophic lateral sclerosis (ALS). OBJECTIVE To study NAA level in serum samples as a(More)
Copper-zinc superoxide dismutase-1 (SOD1) is the second most common mutated gene in amyotrophic lateral sclerosis (ALS). To date more than 150 missense mutations of SOD1 have been reported. The objective of this study was to describe a novel SOD1 mutation and its phenotypic expression. We describe a 74-year-old Caucasian man who began to complain of(More)
BACKGROUND AND PURPOSE A strong association between time to generalization (TTG), considered as the time of spreading of the clinical signs from spinal or bulbar localization to both, and survival was recently identified in patients with amyotrophic lateral sclerosis (ALS). Thus, TTG may be used as an early to intermediate end-point in survival studies. The(More)
