Wentworth Miller reveals he was diagnosed with autism last year.

The 49-year-old Prison Break actor posted about his diagnosis in a lengthy message to his fans.

Wentworth wrote on Instagram, “Like everyone, life in quarantine took things from me. But in the quiet/isolation, I found unexpected gifts.

This fall marks 1 year since I received my informal autism diagnosis.

Preceded by a self-diagnosis. Followed by a formal diagnosis.

It was a long, flawed process in need of updating. IMO. I’m a middle-aged man. Not a 5-year-old. And (it’s a “both/and”) I recognize access to a diagnosis is a privilege many do not enjoy.

Let’s just say it was a shock. But not a surprise.”

“There is a now-familiar cultural narrative (in which I’ve participated) that goes, ‘Public figure shares A, B and C publicly, dedicates platform to D, E and F.’…that’s not necessarily what’s going to happen here. I don’t know enough about autism. (There’s a lot to know.) Right now my work looks like evolving my understanding. Re-examining 5 decades of lived experience thru a new lens,” he added.

He continued, “Meanwhile, I don’t want to run the risk of suddenly being a loud, ill-informed voice in the room. The #autistic community (this I do know) has historically been talked over. Spoken for. I don’t wish to do additional harm. Only to raise my hand, say, “‘ am here. Have been (w/o realizing it).’”

“Oh – this isn’t something I’d change. No. I get – got – immediately being autistic is central to who I am. To everything I’ve achieved/articulated. Oh – I also want to say to the many (many) people who consciously or unconsciously gave me that extra bit of grace + space over the years, allowed me to move thru the world in a way that made sense to me whether or not it made sense to them… thank you,” he continued. “And to those who made a different choice… well. People will reveal themselves.”

Last year, Wentworth revealed that he will not be playing straight characters anymore and will not be reprising one of his most famous roles.
