Curious about a birthmark

I was born with a birthmark on my scalp, originally as a baby it was a small hole to my brain which scabbed over and remains hypersensitive. I've recently finally got my autism diagnosis at the age of 29. 

I was wondering if anybody else with autism has a similar birthmark on their head.

I also have ptsd and depression but that's more to do with trauma from childhood rather than something i was born with.

  • I have been reading people's replies just to learn all the differences

  • Nothing very similar, but up to being about 45 years of age I could suck air through a small hole in the roof of my mouth. It was never commented on by dentists, so it must have been very small. I presumed that the hole communicated with my nasal passages in some way.

  • OP. Some scars do accumulate or lose pigmentation but that isn't the same thing as a birthmark, which I believe does in fact have to be there literally from birth, hence the name.

     I thought I didn't have any, until I went for an eye test where they look right through to the back of the eye wall, and it turns out the thing that I thought was a heterochromia is actually a birthmark in my eye.

  • I do, near my crown. Is slightly textured and raised (yuck) but otherwise unremarkable. Not sure it means anything though
