Hi. My son has aspergers.
It presents very differently than most cases of Autism. It's more of a social thing, and not being able to read facial clues.
Since you are 50 years old, I assume you have worked most of your life, right?? Did you have friends? Were you comfortable in social situations?
Also the hypersensitivity to light and sounds is also one of the traits.
But it mostly affects the male population.
I once went to an Aspergers Support Group meeting in NYC. There were 50 men and exactly 2 women.
It was not diagnosed when you were younger. It wasn't even on the books way back then.
I don't know if a diagnosis would make you feel better or do anything to change your life, but if you want to know, then go for it.
Also, and you might find this very helpful. there are countless message boards for people with aspergers.
Here's a good one, just perfect for you. Lots of people here who were diagnosed later in life.

So go and poke around and you might just find out if you are indeed Aspergers!!!
Best of Luck.
