    I'm 72 and I gave up 30 years ago on trying to fit in with everyone else. So, I don't care anymore whether I'm autistic or just an introvert. Just to let you know I scored 15 out of 15. Good job on the video. Thanks.

    I’m fascinated with how much ADHD and ASD overlap. I was diagnosed with ADHD late in life, which helped me to understand myself better, but I have also taken ASD self tests and scored very high. I also relate with a lot of the points in this video. 🤔

    I...started crying at "You are perceived as rude, but have no idea why." My whole life, I struggled so hard with this. I never understood why people I cared about so much just...suddenly started hating me. And no one ever told me what I was doing wrong. Everyone seems to think I know what I did, but I don't. I think I need to go talk to someone. Thank you.

    When someone messes up my routine, I feel enormous hate for that person. It usually happens when my wife has some of her family for sleepovers. I cannot describe how uncomfortable that makes me feel. It makes me completely rethink my life, and I start dreaming about having my own place, away from my family where I can develop a routine that no one can ever interfere with.

    Now the flip side of this is that sometimes this reshuffling of my routine helps me a lot, because I tend to get stuck in routines that are not necessarily good. It's hard to admit, but sometimes someone messing up my routine is exactly what I need. I get pissed, and that pushes me to do thing I've been postponing.

    It took 40 years and countless times of telling my autistic son, "Don't worry. I did/thought the same thing when I was your age." before I realized I'm autistic. I had five friends who'd already been diagnosed by the time I figured it out . Edit: To clarify my age, I was born in the fall of 1979.

    Hi, I’m a psychology student from London, UK. First of all, the most important thing to know about ASD (Autism Spectrum Disorder) is that it is indeed a spectrum. Meaning there are ‘autistic’ traits that exist in many people to varying degrees, but this won’t necessarily mean that someone with a specific trait can be diagnosed with ASD. Secondly, a very very important thing to remember, is that Psychologists generally always hold off from diagnosing someone with ASD unless their traits actually interfere with their life in a negative way.

    Generally people with ASD have problems with socialising. Not specifically with a type of friend group, but with everyone. This is different from someone who hasn’t been able to find like minded people, this inability to socialise is largely due to neurological factors such as people with ASD having atypical development of certain brain regions such as the amygdala (involved with emotions).

    Some traits of ASD: Inability to really understand what others are thinking even when it is obvious (this is called theory of mind), poor ability to socialise, sensory overload, echolalia (repeating words or phrases under your breath as someone is talking to you), extreme attention to detail (closer focus on parts of a picture rather than the bigger picture), very good at rote imagery tests and certain problem solving puzzles, strong interest in very niche things (such as drainage pipe blueprints or train time schedules), repetitive behaviours.

    There has been research in babies who have had brain scans and have shown markers of ASD. The same babies had a brain scan at 2 years of age and interestingly, not all of the babies with markers of ASD developed ASD. This supports the theory that ASD is largely genetic and heterogeneous, meaning it is rooted in various impairments of brain development which come together and manifest as a neurodevelopment disorder. We know it is genetic because a monozygotic twin (identical twin through splitting of single sperm and single egg into two embryos meaning 100% same DNA) will have about 60% chance of being diagnosed with ASD if their twin is diagnosed with ASD. However if it were the case that it is all genetic, then siblings which share 50% of their DNA would have also have a great chance of inheritance, however it is a roughly 20% chance that a sibling of someone with ASD will also be diagnosed with ASD. This supports the theory that it is genetic but other factors bring about the facilitation of these genes to either come to expression or not. ASD is more prevalent in men and roughly 1 in 100 children across the world live with ASD.

    I hope everyone who reads this takes away this: traits alone are not conclusive for a diagnosis of ASD as many people posses similar traits to a largely varying degree and psychologists place great importance on whether these traits show clear interference with living a healthy life.

    For further research you may Google how the brain of someone with ASD is affected and for reading I would recommend a book by psychologist Uta Frith titled: Autism, a very short introduction.

    One point I think you missed...having no understanding of how neuro-normative people "hook-up". I spent much of my childhood and early adulthood watching other kids in my school(s) forming relationships and thinking "how the hell do they do that?". I literally had no idea and in all honesty still don't. I am now married with three kids but really, I still have no idea how that happened!!

    I was 65 before I finally figured out that I was autistic. I knew I was different pretty much all my life but just didn't know why. I got an official diagnosis when I was 67. Better late than never. I think the only thing you left out was problems with balance and co-ordination.

    It wasn't until I hit my fifties that I realised that I was drinking alcohol in social occasions, and way too much, because I was not comfortable in social gatherings and ultimately did not want to be in these situations. So now I don't go to group meet-ups in crowded places and don't drink at all, it has been such an improvement to my life. And yes, have always been considered weird by others.

    I‘ve been diagnosed with ADHD about a year ago (early 30ies) and I have a sneaking suspicion that there is more to uncover. For example I want and need a routine but sabotage myself in that department. What hit right in the feels in this video was that thing about planning out social situations, considering every possible situation and always being the odd one.
  • Amanda Bevis
    It had never occurred to me that I may be autistic until we were having my son diagnosed. It turned out they thought he was more ADHD and possibly ODD than autistic but durring the various appointments and my own research into the matter It struck me that many of the symptoms of high functioning autism were normal traits in myself.
  • Mary Schlueter
    I am enlightened by your videos. At age 51 I was diagnosed as having ADHD. Now I am 76, and I find myself identifying with most of the characteristics you present here. I have also done quite a bit of reading about autism, and I have scored high on some ASD tests available on the internet. All the help you provide is very welcome.
  • flipflopflapjack
    The greatest and most awkward feeling is when someone brings up a subject you’ve done a deep dive on. It’s great bc you’ve wanted to talk to literally anybody about it for ages but awkward because you know way too much about it and although you only spent a couple of hours researching, they act like you’ve spent years researching and end the conversation quickly bc they didn’t want to know as much as you want to tell them.
  • Shelby Razzone
    15/15 and I’ve had my suspicions. My brother as well questioned if he is too. But our mother is a speech pathologist and insists we aren’t because , in her words, autism is a communication disorder ONLY. I will be watching your other videos to see if you have content about how to approach family members that don’t believe you.

    I hit all 15 of these. I actually found out I was autistic last year through a couple therapists. when I found out my son was autistic about 8 years ago I was in super denial about it. but now I think about it me and him have so many similarities. it's like looking in a mirror lol. but beforehand I always thought his behavior was weird or different not realizing I was doing the same thing in different ways. 😅
  • Mary Sueper
    After pondering, praying and researching, I concluded last year that my brother is autistic. Then within a few months it hit me—so was mom! It certainly explains so much of my painful, lonely childhood. But now I’m wondering about the influence they had on me, and what to do with this knowledge, Being an HSP myself, I tend to chew the cud on things…for ages!
  • condar419
    That was fascinating. Well done!

    I’m curious about the “hyperfast recall” reason… any thoughts regarding how this trait would help people on Jeopardy, or similar shows?
  • Steve McCann
    I didn’t find out until recently and I’m 62 now. Explains a lot in regards to how I was at school and how clumsy I am and so lousy at sports as well as having so few friends. First wife always mentioned how I never looked at her when talking together and thought I was lying when I wasn’t!!
    Only looked at the possibility of having ASD when someone mentioned my behaviour one day and asked if I was autistic. I said no but made me think and after doing a an ASD test found there was a strong possibility that I was. Some say ASC now as the word condition has less stigma than disorder.

    Hunter, I've been in education for 38 years and seen many kinds of kids. I was principal for 10 of those years in a school that had several diagnosed autistic kids. Your video made me happy to see an autistic adult who embraces who he is and works on communicating through his strong attributes. Carry on, Hunter. Many of us really care about people who are "different" in a world where most want to "fit in."

    I am now 63 and have been watching many many many videos on autism in the last 6 months. The more I watch the more like me and my father it sounds. My best friend, that I have had since I was a teenager, has learned to cope with my idiosyncrasies. She is very spur of the moment but realized that I must have a plan and if that plan gets disturbed it throws me off. So when we go somewhere she tries not to vary the plan too much. She tries to limit the changes and I try to adapt to them. But she knows when I can no longer deal with it and we usually stop to eat or return to home so I can relax and get myself together. As an adult I now see this same thing in how my father was. Even to do something as simple as going fishing, he had a check list of things to have, a plan as to where he was going, how long he would be there, and when he would return. The day before he would check all his tackle and his rods and reels to make sure they were in working order.If he said I’ll be back in four hours. He was whether he caught zero fish or the maximum allowed. If he maxed out early he would still stay where he was and usually use that time to organize his tackle box again and make a list of what needed replacing.
