Think Your Body Is Infested With Insects? You're Not Alone. (nationalgeographic.com) 123
Erika Engelhaupt, National Geographic: A few years ago, a man began telling his family members a horrifying tale: There are bugs living inside him. [...] He shows the classic signs of what scientists call delusory parasitosis, or Ekbom syndrome, an unwavering but incorrect belief that the patient's body has been infested with something. For years, entomologists have insisted that these delusions aren't as rare as psychiatrists and the public may think. And now, a study by the Mayo Clinic suggests they're right. The first population-based study of the condition's prevalence suggests that about 27 out of a hundred thousand Americans a year have delusions of an infestation. That would mean around 89,000 people in the U.S. right now are plagued by the condition.
For many sufferers of such delusions, the infestation takes the form of insects or mites, usually tiny and often described as biting or crawling on the skin. Others report feeling worms or leeches or some kind of unknown parasite. Many of the afflicted turn up, eventually, in an entomologist's office. And as the entomologists tell them, only two kinds of arthropods actually infest humans: lice and a mite that causes scabies. Both are easy to identify and cause characteristic symptoms. Bedbugs or fleas might infest a house, but they don't actually live on or inside the human body; they just feed on us and leave. Likewise, there are mites that live on our skin, especially the face, but they're a normal part of everyone's body, much like the bacteria living in our guts.

Not necessarily. Formication is the sensation that feels like something small is crawling on your skin. People with it (I have it occasionally; cancer's a bitch) may initially think that insects are causing it, understandably. However, once you're looking at the part of your skin where it feels like something is walking on you but you see there's nothing there, then you understand that it's a sensation of your nerves.
Delusory parasitosis means you still think the insects are on/in you even when you have evi

Re: (Score:2)
The idea, I think, is that no other arthropods reproduce in humans. Botfies and screwflies can grow inside humans as a result of adults laying eggs from outside. But once they are grown up, they just leave.

Somewhere (likely one of the original two Smalltalk books) there is a cartoon from the development of Smalltalk where the transcript on the screen shows something like "2 + 2" resulting in "3" with the programmer exclaiming something like "It works!".

I have a, er, uh, ah, a friend, who has this. It is a very persistent and realistic sensory illusion. But if you examine the skin, while the sensation is going on, nothing is there. There are no mites, no spiders, no insects, nada.
It can be a symptom of an oncoming migraine. Some forms of migraines are depression of activity in some parts of the brain. Some types of migraines are like electrical storms in the brain, like seizures in parts of the brain. I think the spiders on the skin sensation is part of the second, the brain storms.
With a lot of training you can learn to ignore the sensations, just as in the military you get trained to ignore an itch. But the sensation is still there and very real to the person experiencing it.
There are medications that help with migraines, such as Valproic acid, which appear to reduce the sensation or at least make it less realistic and more tolerable.

There are mites in our skin that we aren't expected to feel but sometimes people report feeling them. There is zero evidence of delusion, a simpler explanation would be that in some conditions people might be sensitive to things that are normally unnoticeable.

I think this delusion is distinct from conditions where there are actual (but phantom) sensations of things crawling on your skin, though the latter could certainly cause the former.
The person experiencing real but neurologically-caused sensations does not generally develop the belief that they are manifestations of actual infestations, though they may thing so at first. Once it is explained and understood that migraines (say) are the cause of these phantoms the patient understands and accepts that is the c
