Onychotillomania Explained

Onychotillomania
Caption:The hands of a subject exhibiting the signs of the neurosis

Onychotillomania is a compulsive behavior in which a person picks constantly at the nails or tries to tear them off.[1] It is not the same as onychophagia, where the nails are bitten or chewed, or dermatillomania, where skin is bitten or scratched. Onychotillomania can be categorized as a body-focused repetitive behavior in the DSM-5 and is a form of skin picking, also known as excorciation disorder.

It can be associated with psychiatric disorders such as depressive neurosis, delusions of infestation[2] and hypochondriasis.[3]

It was named by Jan Alkiewicz, a Polish dermatologist.[4]

The constant destruction of the nail bed leads to onychodystrophy, paronychia[5] and darkening of the nail.[6]

Some cases have been treated successfully with antipsychotics.[7]

One cheap solution suggested by researchers is to cover the proximal nail fold with a Cyanoacrylate glue. "The mechanism of action for improvement is probably related to the presence of an obstacle to picking."[8]
