Variantes Benignas, EEGResumo
A identificação de determinados achados aletrencefalográficos, que são considerados variantes benignas, é importante para que não sejam catalogados como anormais. Entre estes grafoelementos sem significado patológico no EEG, temos a descarga ritmica temporal media (conhecida como variante psicomotora), o complexo pontaonda 6Hz (ponta-onda "fantasma"), as pontas positivas 6/14Hz, os paroxismos epiléticos benignos do sono, as 'wicket spikes', a descarga paroxistica do "carrefour e, mais recentemente, as pontas positivas 28Hz e o potencial 'N". Todas essas variantes da normalidade precisam ser identificadas corretamente e diferenciadas de padrões anormais de significado diagnóstico em pacientes sintomáticos ou não.
