I've seen some studies that point to the idea that even low intake of alcohol over a prolonged period of time might actually decrease brain volume or at least volume of particular brain areas. But of course we don't know the consequence of decreasing the volume of a given brain area either. I mean, one can imagine it's decreasing the size of one's amygdala and making them less stressed. Although there's no evidence to support that.
