| dc.description.abstract | Purpose. In the course of a high-risk study for alcoholism, the middle-latency auditory evoked potentials (MAEPs) of children of alcoholics were explored. Material and Methods. A series of auditory clicks (0.1 ms, 60 dB SL, 1.1/s) were used to record the Pa and Pb peaks of the MAEPs in 15 children of alcoholics with a multigenerational family history of alcoholism, and 17 control subjects, ranging from 10 to 14 years of age. Results. The latency of Pb was shorter in the high-risk than in the control group, and there was also a significant risk group by age interaction on Pa latency. The amplitude of Pa was smaller in the children of alcoholics. Conclusions. The characteristics of the MAEPs of the high-risk subjects did not match the pattern of abnormalities previously observed in chronic alcoholics, which are supposed to be a consequence of the neurotoxic effects of ethanol. Nonetheless, the results showed significant differences in MAEPs between children of alcoholics and controls, pointing to an anomalous pattern of information transmission from thalamus to cortex that should be further analyzed using larger samples in a broader age range. | gl |
| dc.description.abstract | Objectifs. Étudier le risque possible dˈalcoolisme chez des enfants dˈalcooliques par lˈenregistrement des potentiels évoqués auditifs de latence moyenne (PEALM). Matériel et méthodes. Dans le but dˈenregistrer les composantes Pa et Pb, une série de clicks (0.1 ms, 60 dB S.L, 1.1/s) a été délivrée à deux populations dˈenfants âgés de 10 à 14 ans : 17 enfants-témoins et 15 enfants faisant partie dˈune famille dˈalcooliques. Résultats. La latence du Pb était raccourcie chez les enfants dˈalcooliques. Lˈamplitude du Pa était plus petite et il y avait une interaction significative âge/groupe sur la latence de ce potentiel chez ces enfants. Conclusions. Les PEALM des sujets à haut risque ne présentent pas les mêmes anomalies que celles observées précédemment chez des alcooliques chroniques, qui sont une conséquence des effets neurotoxiques de l’alcool. Cependant, les résultats montrent des différences significatives des PEALM entre les enfants d’alcooliques et les enfants contrôles, suggérant une anomalie dans la transmission d’informations du thalamus au cortex. Cette analyse devra être approfondie grâce à des échantillons plus grands et un panel d’âges plus important | gl |
