Despite concerted efforts from pharmacologic research into neuropathic pain, many patients fail to achieve sufficient pain relief with medication alone. For this reason, increasing interest centres on neurostimulation techniques. We assessed whether transcutaneous spinal direct current stimulation (tsDCS) modulates conduction in ascending nociceptive spinal(More)
OBJECTIVES To characterize swallowing deficits in amyotrophic lateral sclerosis (ALS); investigate the delay in dysphagia onset; estimate correlations between dysphagia severity and patients' functional status; identify the symptom(s) most likely to predict dysphagia. MATERIALS AND METHODS A group of 49 consecutive patients with ALS, 14 with bulbar onset(More)
INTRODUCTION Repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are non-invasive techniques able to induce changes in corticospinal excitability. In this study, we combined rTMS and tDCS to understand possible interactions between the two techniques, and investigate whether they are polarity dependent. (More)
BACKGROUND Painful neuropathy is associated with plasticity changes in the nervous system. Standard repetitive transcranial magnetic stimulation (rTMS) is a non-invasive technique used to study changes in cortical excitability and to inhibit pain perception. Deep rTMS is a newer development that allows direct activation of deeper neuronal populations, by a(More)
OBJECTIVE To investigate changes in cortical excitability and short-term synaptic plasticity we delivered 5 Hz repetitive transcranial magnetic stimulation (rTMS) over the primary motor cortex in 11 patients with mild-to-moderate Alzheimer's disease (AD) before and after chronic therapy with rivastigmine. METHODS Resting motor threshold (RMT), motor(More)
Tangier disease is an autosomal recessive disorder characterized by severe reduction in high-density lipoprotein cholesterol and peripheral lipid storage. We describe a family with c.5094C > A p.Tyr1698* mutation in the ABCA1 gene, clinically characterized by syringomyelic-like anesthesia, demyelinating multineuropathy, and reduction in intraepidermal small(More)
Recent studies have shown the involvement of the sensory nervous system in patients with amyotrophic lateral sclerosis (ALS). The aim of our study was to investigate the correlation between the laryngeal sensitivity deficit and the type of ALS onset (bulbar or spinal) in a large series of 114 consecutive ALS patients. Participants were subdivided into two(More)
This retrospective study aimed to investigate the clinical features associated with deteriorated swallow in amyotrophic lateral sclerosis (ALS) patients with spinal and bulbar onset, describe the modification of diet and liquid intake, and assess the impact of dysphagia on the use of riluzole. One hundred forty-five patients were observed periodically every(More)
We investigated whether rapid changes in visual input or dark adaptation modify primary motor cortex (M1) excitability in healthy subjects. Repetitive transcranial magnetic stimulation (rTMS), consisting of 10 stimuli delivered at 5 Hz at 120% of the resting motor threshold, was delivered over the M1 in 14 healthy volunteers. They were instructed to relax(More)
Cerebrotendinous xanthomatosis (CTX) is a rare metabolic disorder caused by the inherited deficiency of the mitochondrial enzyme sterol 27-hydroxylase, which results in reduced synthesis of bile acids and systemic accumulation of cholestanol and cholesterol (Federico et al. 2003). Sterol storage in the central nervous system is the main cause of disability(More)
