Elsi you hit a nerve with me.
I have always had neurological differences that could not be labeled. I do have some spectrum trais such as face blindness (look it up maybe), social skills deficits (which is what my sister didnt understand about me) and trouble with loud noise, smells, etc. I was also very klutzy....many Aspies are. I also struggled in school with a verbal IQ of Superior.
Elsi i never quite fit in to autism but I have a lot in common with it.
And I hate and dont understand and cant do small talk. Its Iike my tongue gets tied! I hate sitting at parties having to talk about trite things. I dont get it.
Ok this is just a vent. But when somebody mentions small talk....I have enough trouble explaing myself while talking with NOT small talk!
It is frustrating. I do better in writing.
SWOT we have a lot in common! I share pretty much all of these traits with you, including the face blindness. (I have a lot of problems with movies and TV because of this - I have a terrible time telling people apart if they have similar coloring and haircuts! And forget it if people shave their beard or cut their hair or put on a mask halfway through. I'm always asking "hey, is that the same guy who did x two scenes ago? Also, I owe a lot of apologies to people I know who I failed to recognize in the grocery store or on the street. If you're out of context, and not family, I probably won't recognize you! Sorry!)
As you yourself have mentioned, there is no definitive blood test or scientific diagnostic for these things - it's all about provider perceptions. They are starting to find some brain differences for some things, but that science is still too young for definitive diagnostics, and how many of us have gotten an FMRI? E has what I consider Aspie TRAITS but did not qualify for a formal diagnosis, though she was diagnosed with ADHD. Spectrum disorders, by definition, don't have a clear cutoff, so providers use a "preponderance of evidence" model that looks at the overall picture and how many areas you fit the model in. Then they decide which side of the line they think you belong in. But in reality, there is no line - just a smooth curve. You might enjoy the Aspie quiz, too! You can explore where you fit on different metrics. Try taking it once with honest answers for where you are NOW, and once with your best guess based on your childhood self. And compare the two. It can be interesting.
My diagnosis was based on a lot of childhood stuff, much of which I have outgrown. If I walked in off the street with my current presentation, without the childhood context, I may not still qualify for diagnosis now, especially since they did away with Asperger's as a separate diagnosis. (I was placed as Asperger's, not Autism Spectrum Disorders (ASD), at the time because I had no language deficits or cognitive delays). As a kid, I was a toe-walker, a spinner, a hand-flapper. I did not engage with other children, though I did well talking to adults who indulged my interests. I had (still have) a lot of problems with motor coordination which I have since learned is a problem with knowing where your body parts are in space (proprioception). I was hopeless at sports, never learned to ride a bike or catch a ball. I still can't catch! This is an ongoing joke with my kids. I had (still have) a lot of sensory issues. I spent a few years basically dressing in muumuus (they were not a trend then) whenever I could get away with it because I couldn't stand the feel of anything tight against my skin. I would have preferred to be nude if it was socially acceptable. Now I wear pretty much all identical, loose-fitting flowey clothes that are thankfully much more acceptable now than they used to be - a summer wardrobe and a winter wardrobe. I still have problems with sensory overload with lots of visual stimulus or bright lights - I shut down in big stores. That's another reason I don't like movies - it's hard for me to process visual and auditory stimulus at the same time. I love books, podcasts, music and art, but not moving, talking pictures! It's too much. But I've largely either outgrown or learned to accommodate my social deficits. I'll never be a socialite but I don't think most people think of me as weird anymore, just perhaps a bit eccentric and set in my ways. I like my routine and don't leave the house a whole lot. But I've built a successful business and interact well with my clients and partners. They seem to like me OK. And I'm good with my work.
I don't know if I need the diagnosis now, so much as I needed it to make sense of my past. And become comfortable with who I am.
