Formication
 | This article is a stub. |
Formication is the sensation of insects crawling on or within the skin, when there are no bugs found. Skin crawling sensations may also be part of paresthesia, which is caused by disrupted nerve sensations in the body.[1]:282
Causes[edit | edit source]
Delusions[edit | edit source]
Formication can occur with delusions of parasitosis, which is also known as parasitophobia. This is the false beliefs that bugs are crawling in or under the skin, and typically occurs in people with schizophrenia or obsessive-compulsive disorder, who may go to extreme lengths to try to remove or kill the presumed bugs.[1]:102
Nerves[edit | edit source]
Crawling sensations affecting the skin may be caused by disrupted nerve signalling.
Malnutrition[edit | edit source]
Formication can be caused by beri-beri, a disease caused by inadequate levels of thiamin, better known as vitamin B1.[2]
