I have known for some time that I have a double crown - or whorls of hair - on the top of my head. I've been told that it's slightly unusual, but didn't pay much attention to it. Then, a couple of days ago, just out of curiosity, I decided to Google it to see how rare it actually was, and it came up with a whole load of sites with discussions as to whether it is linked to autism or developmental delays or not, though I couldn't find anything giving concrete scientific evidence for this. Here are a couple of such sites
There are numerous such sites. Have you ever heard this? Personally I think it's just probably an old wives tale, and without concrete scientific proof I can't accept it as valid, but the numerous references did pique my curiosity
Does anyone else have a double crown?
