Jerry Seinfeld believes he has autism: 'I think I'm on the spectrum'

Comedian Jerry Seinfeld has a revelation make -- and it's no laughing matter.

Comedian Jerry Seinfeld has a revelation to make -- and it's no laughing matter.

The 60-year-old former sitcom star told NBC "Nightly News" anchor Brian Williams Thursday that he thinks he is slightly autistic.

"I think, on a very drawn-out scale, I think I'm on the spectrum," Seinfeld said. "Basic social engagement is really a struggle. I'm very literal, when people talk to me and they use expressions, sometimes I don't know what they're saying," he added. "But I don't see it as dysfunctional, I just think of it as an alternate mindset."

Seinfeld is not the first celebrity to come forward about autism symptoms or a diagnosis with the condition. Actress Daryl Hannah, singer Courtney Love and comic legend Dan Aykroyd are among the famous figures who have gone public about having been "on the spectrum" as well.

In fact, Aykroyd has indirectly credited being diagnosed with Asperger's as inspiration for his iconic blockbuster "Ghostbusters," which just celebrated its 30th anniversary. "One of my symptoms included my obsession with ghosts and law enforcement—I carry around a police badge with me, for example. I became obsessed by Hans Holzer, the greatest ghost hunter ever. That's when the idea of my film 'Ghostbusters' was born," the "Saturday Night Live" alum told The Daily Mail in December 2013.

For his part, Seinfeld has both donated to and headlined charity events on behalf of autism, including Autism Speaks and 2012's "Night of Too Many Stars." He still does stand up comedy tours and stars in a popular web series called "Comedians in Cars Getting Coffee." He currently resides in New York with his wife and three children. He told Williams that despite that fact that he doesn't need the money performing on the road keeps him feeling fulfilled. 

"I know that that's the healthiest thing I can do," Seinfeld said. "If you're more interested in what you have achieved or what your financial position enables you to do than that thing that got those things, you're screwed -- in my opinion, you're screwed."
