<b>Background: </b> Patients with Parkinson disease (PD) may present various types of pain. In some instances, no cause can be identified and pain is considered a primary disorder (primary central [PCP]). We hypothesized that PCP in patients PD (PD-PCP) due to dysfunction pathways or the processing inputs CNS. <b>Methods: carried out psychophysical neurophysiologic study 9 PD-PCP, without (PD-NoP), healthy control subjects. assessed clinical characteristics pain, performed quantitative...
The use of cannabidiol in some neurological conditions was allowed by Conselho Regional de Medicina São Paulo and Agência Nacional Vigilância Sanitária (ANVISA). Specialists on behalf Academia Brasileira Neurologia prepared a critical statement about other cannabis derivatives diseases.
Transcranial direct current stimulation (tDCS) is a technique that delivers weak electric currents through the scalp. This constant induces shifts in neuronal membrane excitability, resulting secondary changes cortical activity. Although tDCS has most of its neuromodulatory effects on underlying cortex, can also be observed distant neural networks. Therefore, concomitant EEG monitoring provide valuable information mechanisms tDCS. In addition, findings an important surrogate marker for and...
Histoplasmosis of the central nervous system occurs in a significant percentage patients with Histoplasma capsulatum infection, but has usually been described association immunosuppression and/or disseminated histoplasmosis. We aim to review clinical and laboratory features isolated histoplasmosis immunocompetent host by presenting series 11 cases this condition. Most these presented headache, meningeal irritation signs mental status changes, comprising somewhat different picture from that...
There is a lack of evidence on the clinical efficacy and safety recently released Chinese botulinum toxin serotype A (Prosigne) for treatment focal dystonias hemifacial spasm. Determining more precise role Prosigne in such conditions paramount importance, because type treatments have huge economic implication health services, especially developing countries. The aim our study was to compare blepharospasm spasm comparison Botox. We performed double-blind, randomized, crossover enrolling 26...
Background. Neuropathic pain (NP) is a very frequent and unrecognized condition in clinical practice. Therefore, it important to have reliable instrument assess subtypes various cultures. The Leeds Assessment of Symptoms Signs (LANSS) has been widely used validated many countries. Up now, there no reliability study this Brazil.
Quantitative sensory testing (QST) is defined as the determination of thresholds for perception under controlled stimulus. Our aim was to validate a new QST device Brazilian sample. In 20 healthy adults, thermoalgesic were assessed using prototype (Heat Pain Stimulator-1.1.10; Brazil). A 30 × mm² thermode with 1°C/s stimulus change rate applied. Thresholds three consecutive stimuli averaged in two different sessions separated by at least weeks. Additionally long thermal heat pain performed....
Abstract We studied the sudomotor skin response (SSR) in patients with Parkinson's disease and without symptomatic hyperhidrosis. The study was carried out 13 who complained of excessive sweating 37 did not have sweating. Patients were matched for age, sex, degree impairment, duration disease, number severity autonomic disturbances. Excessive involved mainly face, head, trunk. SSR recorded from palm hands to electrical stimulation median nerve at wrist. analyzed onset latency, peak...
OBJECTIVE: Parkinson's disease is a common neurodegenerative disorder characterized by motor disabilities and increasing dependence on others for daily life activities with consequent impact patients' caregivers' quality of life. METHOD: A cross-sectional study was performed in which assessed the WHOQOL-BREF questionnaire 21 patients their respective caregivers. RESULTS: Significant differences between caregivers were found physical (p < 0.001) psychological = 0.002) domains. In group...
Neurologic impairments in female heterozygotes for X-linked Adrenoleukodystrophy (X-ALD) are poorly understood. Our aims were to describe the neurological and neurophysiological manifestations of a cohort X-ALD heterozygotes, correlate them with age, disease duration, mutations, X-inactivation serum concentrations marker neuronal damage, neuron-specific enolase (NSE). All 45 identified our region, previous VLCFA molecular diagnosis, invited be evaluated through myelopathy scales JOA SSPROM,...
To determine the prevalence of amyotrophic lateral sclerosis (ALS) in city Porto Alegre, Brazil.We conducted an extensive investigation clinics and hospitals that provide specialized assistance to these patients, contacted neurologists regional association people with ALS.On July 31, 2010, 70 patients were alive diagnosed sclerosis. Considering population living same period (1,409,351), estimated was 5.0 cases per 100,000 (95% CI, 3.9-6.2), being higher for men (5.2/100,000 95% 3.6-7.2) than...
Patients with meralgia paresthetica (MP) usually experience not only paraesthesias and decreased tactile sensation, but also painful dysesthesias in the distribution of lateral femoral cutaneous nerve (LFCN). We aimed at assessing whether there is any functional impairment small fibres LFCN patients MP.We carried out a clinical, psychophysical neurophysiological study 14 MP healthy control subjects. assessed pain last 2months, thermal thresholds conduction by using visual analogue scale...
ABSTRACT The aim of this study was to describe the results a Brazilian Consensus on Small Fiber Neuropathy (SFN). Fifteen neurologists (members Academy Neurology) reviewed preliminary draft. Eleven panelists got together in city Fortaleza discuss and finish text for manuscript submission. fiber neuropathy can be defined as subtype characterized by selective involvement unmyelinated or thinly myelinated sensory fibers. Its clinical picture includes both negative positive manifestations:...
