I think that to go with the general fatigue implied by the stat loss it would be more like a normally intelligent character having a bout of absent-mindedness. Not a complete retard, just not as witty and lucid as normal. Int is one of those tricky factors that isn't cleanly understood enough to roleplay it well in most cases.

After your 10th or 20th death though the charm of roleplaying it generally seems to wear off in favor of just wanting to get your grave back so you can resume playing normally :P
