HEY YOU, are you questioning autism or know someone who has autism, but don't know where to start with learning about autism? Here's a little guide! (note: please do not use any of this to self diagnose, do research outside of social media and if it is safe and available to you, please consult with licensed professionals for any type of health advice)
Now, what IS autism at it's core?
Autism spectrum disorder (ASD or autism): Autism is a neurological condition that affects many parts of the brain, it affects sensory processing, emotional regulation, social skills development, motor skills, etc. it is a diverse spectrum where everyone with it can experience it very differently, so do not assume that if you meet one person with it that you know all there is to it.
People with autism have support needs and levels, but what ARE support needs and levels and what's the difference between them?
Support needs can be 1 of 2 things typically
1: how much support you need on a regular basis
"I'm high support needs and use high tech AAC to communicate"
2: how much support you need right then
"I am having a low support needs day"
This can be alongside a diagnosis or part of general language
Levels are a baseline for what your support needs usually are, these can change but are not an overnight type thing usually
Levels are typically part of diagnosing autism, I am diagnosed with level 2 autism with moderate to high support needs. I do not have low support need days other than what is low support needs for ME (if I am able to brush my teeth on my own at all that is a low support needs day)
Level 1 autism is also referred to as low support needs autism
Here's an important distinction: low support needs does NOT mean no support needs. While someone with high support needs may need help dressing/can't change themselves, someone with low support needs may need a reminder to get dressed instead. Both are requiring support, one needs more help, the other needs less, this does not mean one is more valid or one is less valid, they are both deserving of support.
Most people with low support needs autism (assuming they do not have other disabilities that complicate them) can usually live mostly or fully independent lives, support for them in adulthood is typically closer to needing reminders, needing people to plan things in advance, work accommodations, sensory aids, dim lighting, etc.
In childhood, support for them (if they get early intervention, though usually many people with LSN do not get early intervention) usually means being allowed sensory aids, teaching social skills, practicing daily living skills, teaching self regulation (all children need to be taught this, but autistic children regardless of level or support needs need this more), etc.
Level 2 autism is referred to as moderate support needs autism. There is lots of variation here more so than in level 1 or 3, that's because this is where people are placed when they don't quite fit either box enough
Here's an important distinction: moderate support needs can look entirely different for each individual. Across the whole spectrum everyone's autism is different, yes, but level 2 has more variation than level 1 or level 3, so if you meet one person with level 2 who has little to no support needs in communication and comes off as just socially awkward and then you meet another person with level 2 autism who uses AAC that does not mean the other person was lying about being level 2, it means their support needs were higher in areas other than communication and social skills
In adulthood, support for them also varies drastically. Some people with MSN can get by independently, some people will always need a caregiver, whether that caregiver has to be with them daily, or comes to visit once a week to make sure things are going fine. Support can vary anywhere from reminders and alarms, to help with executive function issues, regulation skills, helping with things like paying bills, making grocery lists, helping with clothing, etc.
In childhood, support for level 2 autism often looks like sensory aids, commonly stuff like noise cancelling headphones, sunglasses, weighted blankets or plushies, fidgets, etc. helping them to talk to others, teaching social and/or verbal skills, focusing on teaching daily living tasks that they might struggle with (cleaning, folding clothes, doing the laundry, bathing, etc.), they may or may not attend ABA therapy or other similar therapies to help (we are going to assume that these are helpful therapies, not the abusive practices outdated places use, but places that are actually trying to help)
Level 3 autism is referred to as high support needs autism, people with high support needs are *typically* incapable of ever being fully independent and will usually always need lots of support
Here's an important distinction: lack of independence/full independence does NOT mean low intelligence or that they want to be babied, or that they have no thoughts. Autistic people with high support needs have thoughts as complex as anyone's, most do not want to be talked down to like toddlers if they are grown adults.
In adulthood, support often looks like frequent breaks during stressful activities, teaching daily living skills, job skills if they are able (not all are able and there's nothing wrong with that!), teaching self regulation, needing reminders and alarms, help to get ready for the day, hygiene help, executive function help, they may need an AAC, etc. many people with HSN are unable to live without a part time or full time caregiver. This is not due to laziness or unwillingness to succeed, this is due to physical incapability of being able to live fully independent lives, do not treat it as anything other. They are typically able to still live full and meaningful lives if they have the right supports.
In childhood, support often looks like sensory aids, reminders and alarms, help with basic tasks, they may need to be put into special education classrooms (nothing wrong with that I don't want to see any bullying or joking about that), AAC, often times ABA or similar therapies are very helpful for children with HSN autism (again, we are assuming non harmful practices, not the harmful outdated ones), lots of help with regulating themselves, teaching social and/or verbal skills, etc.
You can also have mixed levels or levels with a support need label too, such as level 1/2 or level 2/3, or like me I have level 2 autism with moderate to high support needs, that's how I was diagnosed. I won't go into full detail about all of that because that'd take way too long lol but I think y'all get the gist of that stuff anyway
Sensory aids can look like: fidget toys, weighted blankets, sensory swings, weighted vests, noise cancelling headphones/ear defenders, sunglasses, etc.
Their purpose: most sensory aids have three main goals
1: introduce good stimuli, this can be fun, calm, grounding, etc. such as fidget spinners, chewelry, tight clothing, etc.
2: reduce external stimuli, when something is too loud ear defenders can help block the noise out, or if things are too bright sunglasses can help that too
3: Mix of both, for an example: weighted blankets can both reduce external stimuli (hiding under it to block out noise and light), while adding a calming and grounded stimuli (steady weight)
AAC: this is short for augmentative & alternate communication (I think that's it? I might be wrong pls correct me if I am I'm bad at remembering stuff like that 💔)
AAC is ways for people who lack verbal communication skills to still communicate, this is not exclusive to autistic people, anyone can use an AAC.
High tech AAC: An example of high tech AAC is tablets with AAC programs or apps, so when they press a button it speaks for them
Mid tech AAC: I'm kind of tired and can't think of a good example rn, I'll come by and edit this later, but I think like those little things with buttons you can buy on amazon that have a limited vocabulary but can speak for you would count maybe?
Low tech AAC: this can be picture boards, pointing, gestures, etc.
ABA therapy: I believe ABA is short for applied behavioral analysis therapy. I think, I'm not sure tho. Again, pls correct me if I am wrong. Historically, ABA has been abusive and harmful to autistic people, in the past it was not used to help autistic people, it was a way to try to force them to conform, alongside punishments if they couldn't. Nowadays, ABA therapy in most places has gotten a reform, now they mainly focus on teaching regulation skills, helping with harmful behaviors, etc. and some places that treat autism but aren't ABA may still call themselves ABA therapy since that is, I believe, the only insurance approved therapy for autism
(take these below parts with a grain of salt I got this information from Google and so some of it may be inaccurate, if it is please correct me and I'll fix it!)
The brain has physical differences
In autism, the cerebral cortex (front and temporal lobes) is bigger in early childhood around 1-3
The frontal lobe is responsible for planning, social behaviors, and executive function
The temporal lobe is responsible for language and sensory processing
As they grow up though, this part of the brain either normalizes, or in some cases even shrinks
The amygdala is often enlarged in autism, which is responsible for emotion and threat detection. This can lead to social anxiety, heightened emotions, inappropriate responses to fear and anxiety (too intense or not intense enough), etc.
The cerebellum is often times smaller in autistic individuals, this is responsible for timing, coordination, movement, and cognition
This affects motor skills and motor planning, timing of social interactions, sensory integration, and cognitive coordination.
Corpus callosum is the connection between hemispheres, this is often smaller or thinner in autistic people.
This often contributes to odd interpretations of sensory input, uneven skill profiles, and differences in language lateralization
The hippocampus is sometimes reported to be larger, some are reported as average
When it is larger, it affects emotional memory processing
Basal ganglia is responsible for habit formation, motor control, and repetitive behaviors.
The caudate nucleus is often found to be enlarged which relates to repetitive behaviors and restrictive interests and is also involved in reward processing
Connectivity differences, in autism it is often found that neurons are overactive in local areas, but are under active and have weak communication between areas with more distance
This explains intense focus on details, difficulty with integrating different types of sensory input and other sensory processing issues.
For people who suspect they may have autism and read this because of that:
I hope this is helpful, and again remember this is not a professional testing tool, this is to spread awareness and teach, if you find any of this stuff relatable try to talk to a professional if you can, if you cannot (no money, no accessible testing places, it's unsafe, etc etc) then do research outside of social media too
To people who read this because they met someone who is autistic:
Just remember that this is a real person, don't baby them or treat them less than. They need help, they don't need infantilization or bullying. I'll make a second post at some point about the actual symptoms of autism in general and going more into depth about that, and how to interact with people with autism
