Study on P300 potentials in patients with first cerebral stroke / 中国实用内科杂志

ABSTRACT

Objective To explore the change of P300 potentials in first cerebral stroke patients,and to find the objective index in judging the cognition in these patients.Methods P300 potentials test was used for sixty patients with their first episode of single loci stroke and sixty-two healthy people.The results were compared in the two groups.Results Latency periods of N 2 and P 3 of P300 potentials in cerebral stroke group were longer than those in the controls,the amplitude of P 3 of P300 potentials in cerebral stroke group was lower than that in the controls.There was significant difference between the two groups(P0.05).Conclusion P300 potentials can reflect the cognition in cerebral stroke patients,which has remarkable clinical value in making reasonable treatment plan.
