Gender-specific differences in the onset of alcohol dependence were confirmed. This is in line with the telescoping effect, where a later onset and a more rapid development of dependence in women were described. Under the assumption of a gradual development of consequential organ damage, brain atrophy seems to develop faster in women. As shown in other organs (i.e., heart, muscle, liver), this may confirm a higher vulnerability to alcohol among women.

Abstinent alcoholic patients displayed an increase in mu-opiate receptors in the ventral striatum, including the nucleus accumbens, which correlated with the severity of alcohol craving. These findings point to a neuronal correlate of alcohol urges.

With respect to drinking behaviour, cue exposure and standard cognitive-behavioural treatment seem to be equally effective for patients with a moderate severity of alcohol dependence. Further studies are necessary to specify criteria for differential treatment indication.
