Test-retest reliability of visual-evoked potential habituation

Objective Habituation of visual-evoked potentials (VEPs) is typically described as deficient interictally in migraine patients, supposedly indicating altered cortical excitability. Use of this parameter for monitoring changes over time, e.g. under treatment, requires demonstration of test-retest reliability. Methods VEPs were recorded interictally in 41 episodic migraine patients and 40 controls. N75–P100 amplitudes were measured over six consecutive blocks of 75 VEPs each. Amplitude regression slopes and block ratios were used to quantify VEP habituation. Test-retest reliability was assessed over 15 minutes and two to three weeks. Results Controls showed significantly more negative VEP habituation slopes than migraine patients (–0.21 ± 0.40 vs. 0.04 ± 0.46 µV/block, p

Authors: Machado-Curbelo C Abstract The main characteristics and challenging symptoms of COVID-19, caused by the novel coronavirus SARS-CoV-2, are related to re-spiratory distress. Although most patients have mild symptoms such as fever, headache, cough, myalgia and anosmia, some develop acute respiratory distress syndrome, leading to death in many cases. Human coronavirus (CoVs) were responsible for two previ-ous worldwide outbreaks: Severe Acute Respiratory Syndrome (SARS-CoV) and Middle East Respiratory Syndrome (MERS-CoV). Several reports of these outbreaks demonstrated that these diseases affected the central ...

Conclusion: The burden of disease (BD) increased by 1.6% from 1990 to 2015. The main causes were migraine, CVD, and NE. ADD and NSC doubled the DALY in this period. These diseases represent a significant cause of disability attributable to the increase in the life expectancy of our population among other factors. Priority actions should be taken to prevent and treat these causes.RESUMEN Introducci ón: Los indicadores de carga de la enfermedad evalúan el impacto que producen las enfermedades en una población. Integran la mortalidad y discapacidad en un solo indicador. Esto permite fijar prioridades para...
