Evidencias de compromiso cerebral en el estadio crónico de la enfermedad de Chagas obtenidas por medio del potencial P300 y de electroencefalografía cuantificada

It is already known the involvement of the peripheral nervous system in chronical stages of Chagas disease. Tomographic and neuropsychological evidence of brain compromise has been included recently. In order to evaluate the neurophysiological counterpart of cerebral involvement, we studied P300 evoked potential and quantified EEG (qEEG) of 35 patients (2655 years), and compared to an equal number of control subjects (2955 years). We have found increased P300 latency compared to the control group (331.24 ± 24.02 vs 318.86 ± 23.18) (p=0.01716). qEEG showed lower relative Beta 1 power in the p...
