One particular person I cared for with this dysfunction would stroll as much as strangers, stand nearer than could be comfy, and say loudly, “You’re good-looking!” One other would eat virtually something ignored within the kitchen. One girl I handled with this dysfunction tried to choose up males from a restaurant — whereas her husband was sitting on the subsequent desk. A beforehand sort and shy grandfather with frontotemporal dementia started to ask his daughter-in-law for sexual favors.
