Not everyone thinks that Aspergers syndrome and autism should be linked together. This can depend on which camp the Psychiatrist sits in. Use your British health care system to your advantage and get a proper diagnosis, then any doubts can be removed. A good book to read is by Tony Attwood, A Brit who has his practice in Australia. The Complete Guide to Asperger's Syndrome, is considered one of the top 5 books on this subject. Doctor Tony is one of the top 3 in the world regarding Asperger's and autism.
I was diagnosed with Aspergers by a Psychiatrist only a few years ago. After a long life of frustration and confusion many of my life's quirks and difficulties finally made sense to me. Many Aspergers people have very high sensory perceptions. A couple of examples, I had my hearing tested many years ago and it was off the charts, the technician had to test twice because he had never seen such results. Another, my sense of touch is also off the scale, clothing tags can drive me crazy. I can literally feel mosquitos and flys land on me. I have been an underdresser for well over 25 years because of my choices in fabrics that give me better tactile comfort.
I still see my Psychiatrist twice a year, the last time I was dressed to my comfort level. That level being a camisole, panties, hosiery and skirt, as some would say, a miad. She has been a great help to me in accepting my quirks and understanding them.
Many Psychiatrists also believe there is a strong correlation between CD'ing and being on the spectrum. More study needs to be done on the subject.
