The 60-year-old was diagnosed back in 2005, admitting it took two years to realise what was wrong.
During a chat on UK chat show Loose Women, Hegerty said, “I think that I saw a documentary on TV (about Asperger’s) and there was just something about it that rung bells in my brain.”
“I remember in my diary writing, ‘I’m beginning to suspect again that I have Asperger’s syndrome.’”
The government explains Asperger's syndrome is a part of one of the autism spectrum disorders. It is a lifelong developmental disability that affects how people perceive the world and interact with others.
The Chase star explained that her diagnosis "made sense of a lot of things".
“Some people say, ‘You don’t seem autistic. Where do you keep your autism?’ I’m like, ‘It’s behind my front door and you’re not coming in!’”
This isn't the first time Hegerty has touched on her illness.
In the past she's shared the importance of getting help.
“On New Year’s Day 2008 I had two bailiffs turn up on my doorstep because I had so little income I had not been paying bills,” she said. “I just couldn’t quite get it together," she recounted on previous Loose Women interview.
“A terribly helpful social worker named Jeff Mackenzie came and said to me, ‘Don’t worry about a thing, I will open the mail, we will get the bills paid, I will get you filling in the forms so you can actually be on benefits.’"
“He also sent me to someone who helped me fill in forms to get disability living allowance which I still get."
