(Trigger warning for caps) As a general note for ASD/ADHD only people with one or both of those disorders can use the term hyperfixation. Also ASD is caused by brain structure and is LIFELONG, i cannot stress this enough i cant be cured it cant be gained when your like 30, if you have it from birth you have it life long, and if you don’t you aren’t and will never be autistic. Also not all autistic people hyperfixate on trains, like I don’t even care about them, now if you talk about pikmin i will leap up and down with joy /hj. Also not all autistic people are white males, it effects everyone and everyone differently. And not everyone who is autistic is good at math/science/generally intelligent, I cannot stress enough, AUTISM IS A SPECTRUM. it’s best described by me at least as several sliders, some autistic people need less supports, some need more, I fall in the middle but that doesn’t make me or anyone else LESS/MORE AUTISTIC.
