Disinhibited social engagement disorder(indiscriminately social disinhibited type) early persistent harsh punishment which results in the child showing no inhibitions to approaching adults. Example: willingness to immediately accompany an unfamiliar adult figure somewhere without first checking back with caregiver. Crf- elevated or restricted corticotropin-releasing factor; indicates heightened activity in the hpa axis.

The hippocampus plays a role in regulating the hp axis and in learning and memory.
