Rob McElhenney opened up Wednesday about his recent diagnoses of “a host of neurodevelopmental disorders and learning disabilities” at the age of 46. “It’s not something I would normally talk about publicly but I figured there are others who struggle with similar things and I wanted to remind you that you’re not alone,” the It’s Always Sunny in Philadelphia star said on Twitter. Neurodevelopmental disorders include ADHD, autism and other conditions that typically appear during a person’s developmental period, according to the EPA. McElhenney didn’t get into specifics in his tweet, but said he plans to “go through the full diagnosis/prognosis” on an upcoming episode of The Always Sunny Podcast. “You’re not stupid. You’re not ‘bad’. It might feel that way sometimes. But it’s not true,” he added.
