Yes, it depends on if you decide to mask/hide it or let it be. I stopped masking and I have gained more stims and tics suddenly. It really depends on if you are hiding what you didn't know you actually did before. I hope this makes some sense to you '^^

I'm not sure to be completely honest. I struggle mostly with the social aspect of ASD. I took social skills classes in middle and high school and I feel far less limited in social situations then I did when I was younger...although I still struggle with people's intentions, cues, and tones. I also struggle with Sensory imput/over stimulation but that is very mild compared to when I was younger. So I guess I am saying it went the other way with me.

Autism does not “progress” because it is a neurotype—not a disease. However, different traits, especially stimming, can pop up randomly when you stop masking, or are no longer able to mask. It’s not a bad thing—it can mean that you’re living your life authentically and you’re comfortable enough to be yourself—but it can also be a sign that you’re being pushed too far, or receiving too much pressure to conform. Autistic people also tend to be prone to things like OCD and Tourette’s, though, which can cause similar behaviors and do progress under certain circumstances.

No, because it's basically a trait not a disease. Behaviors can change and increase tho. Like because over or under stimulation. Which can cause meltdowns.

Like some of the other replies said, its not really 'progressing' but how much you are masking. For example you might stim and stutter more when your in a comfortable environment vs an uncomfortable one.

My 'tics' started coming out more after a crisis and I was too mentally exhausted to mask. My therapist explained they weren't necessarily tics, but more likely stims.

I relate to Avis. After a medical crisis related to me being autistic, I had tics. At first they really were tics, I had absolutely NO control over. Now they are more like sudden stims, I can suppress them but they do come out of nowhere.

They aren't likely to be tics but rather stims. Stimming is kind of like having tics, but kinda different. I'm not good at explaining. You can develop some over time, of course, but autism doesn't exactly progress, it's more related to masking or unmasking.
