Repetitive Behaviours- Skin Picking

Greetings Earthlings! 🙂

Today I’m going to give you an insight into a particular form of repetitive behaviour- skin picking.

Ok- I know it sounds disgusting, but it is common for those with autism! The statistics are limited, but as many as 14.8% of autists exhibit this type of behaviour.

Skin picking, also known as neurotic excoriation or dermatotillomania  (I really do like the sound of these terms! 😀 ), is characterized by excessive rubbing, scratching, digging, squeezing and gouging of healthy skin. In chronic cases, the urge to pick and scratch can lead to scarring, tissue damage and infection.

If I were you though I probably wouldn’t look the condition up…some of the pictures of these chronic cases are disgusting!

In my own experience, I have a mild tendency towards skin picking. I prod and poke at bites and burns, pick at cuts and scabs etc., but squeezing my skin would be my biggest issue- I find it so addictive and it can be quite hard to stop! I also have a particular tendency to press hard against injured skin, like pinching an infected finger or pressing a sore toe against a hard surface- for some odd reason I find it comforting! It hurts, but I feel better about the injury after doing it. I suppose it must link back to the calming sensation of deep pressure stimulation or something!

Now before we call the men in the white coats, let’s see if there’s a physiological reason for all of this! 😛

Research suggests that the dopamine pathway may play a particular role in this behaviour.

Dopamine is involved in reward motivated behaviours in the brain. Drugs such as cocaine and methamphetamine activate dopamine, which is thought to contribute to the sensation of skin crawling and subsequent picking often experienced by addicts. So experts believe that dopamine dysfunction may be at play in this behaviour.

As I’ve discussed in other posts (sleep, ADHD, curiosity, inside the autistic brain etc.) dopamine is often dysregulated in the case of autism, so it stands to reason that this neurotransmitter may play an important role in skin picking behaviour in ASD’s.

Other experts point to a psychological reason for the behaviour as there is a strong link between skin picking and co-morbid psychiatric diseases. Skin picking is thought to act as a form of  communication in times of stress in the case of autism and is believed by some to act as a sensory outlet for sensory stimulation and or soothing.

Furthermore, as I’ve previously discussed, we autists tend to have more sensitive skin than the average person, this too could influence our tendency towards picking and scratching our skin.

Ah- so I’m not crazy after all! 😉

But is there anything we can do to manage it?

Dermatologists and physicians find this one particularly difficult to treat and often seek drug and behavioural interventions to counter skin picking.

For me personally, this is difficult to advise as the reasons for picking differ from person to person, annnnnnd I tend to indulge the behaviour rather than avoid it 😛

However, I have been making conscious attempts to reduce the frequency in recent years to help protect my skin, and to avoid looking like a weirdo in public! Don’t want people thinking I have fleas if I persistently keep scratching myself!

The best advice that I can give is to keep your hands busy- if they’re occupied, you won’t pick! Gaming and crafting I find can be useful to keep my hands from wandering 🙂

So there we are Earthlings! 🙂 Hope I didn’t disgust you all with this post! 😛

Enjoy the weekend everyone! 🙂
