Chronometrical analysis of event-related potentials and reaction time in patients with multiple lacunar infarcts / Hisao TACHIBANA in Cognitive Brain Research, 1-3 (October 1993)

Public ISBD [article]  inCognitive Brain Research > 1-3 (October 1993) . - p.193-196 Titre : Chronometrical analysis of event-related potentials and reaction time in patients with multiple lacunar infarcts Type de document : Texte imprimé et/ou numérique Auteurs : Hisao TACHIBANA, Auteur ; Kazuo TODA, Auteur ; Kazumi ARAGANE, Auteur ; Minoru SUGITA, Auteur Année de publication : 1993 Article en page(s) : p.193-196 Langues : Anglais (eng) Mots-clés : Event-related-potential P3 N2 Reaction-time Multiple-lacunar-infarct Cognition Index. décimale : PER Périodiques Résumé : We measured the visual event-related potentials (ERPs) and reaction time (RT) in 31 patients with multiple lacunar infarcts and 18 age-equivalent normal subjects. The N2 and RT latencies of the patients were significantly longer than those of normal subjects, although P2 and P3 latencies did not differ between the two groups. However, the time from N2 to RT did not differ between the two groups. These observations suggest that the impairment of cognitive information processing in these patients arises from an uncertainty in classifying the perceived event, while motor organization time is relatively well preserved. In addition, the N2 latency may be more sensitive in detecting cognitive impairment in such patients.
