The present study indicated that minimal advice, as offered to group C, was associated with reduced drinking as much as the brief intervention, as offered to groups A and B, given over a 3-yr period. Furthermore, in the routine setting of the general practice office, the effectiveness of the brief intervention may not be as good as in special research conditions. The factors possibly reducing the effectiveness in a routine setting are unknown. Thus, different methods of implementing brief intervention need to be evaluated to find better ways to support general practice personnel in their efforts to help heavy-drinking female patients to reduce their drinking.
Simultaneous auditory processing between the hemispheres was studied with a whole-head magnetometer in 13 abstinent chronic alcoholics and 10 healthy control subjects. Auditory stimuli were presented monaurally with interstimulus intervals of 0.5 and 2.5 sec in different blocks. The NlOOm response, which contributes to stimulus detection, was significantly accelerated in the hemisphere ipsilateral to the ear stimulated in abstinent alcoholics. The MMNm response reflecting automatic stimulus-change detection peaked earlier in alcoholics, and the ipsilateral NlOOm latency correlated significantty with the abstinence duration. These results suggest that auditory processing is accelerated in the auditory cortex ipsilateral to the stimulated ear in chronic abstinent alcoholics and that the accelerated processing is at least partly reversible. This may be caused by the hyperexcitation in the brain related to the ethanol withdrawal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
