Jerry Seinfeld sparks fears for his health after fans spot worrying detail in his interview with Graham Bensinger

Fans have expressed fears for Jerry Seinfeld's health after spotting him trembling in a new interview.

The 70-year-old comedian's appearance on In Depth with Graham Bensinger on Saturday, prompting many to encourage him to go and see a doctor.

During the interview, which was filmed at the end of March, Jerry reflected on his impressive career and spoke adoringly about his family life.

But viewers couldn't help but notice how he appeared to repeatedly shake his head throughout the conversation.

'Go see your physician,' urged one, who voiced their concern underneath a clip of the interview shared to Facebook.

'He has a tremor,' claimed another, while a third said: 'When did he start having motor issues? Had no idea.'

A fourth feared he may have Parkinson's and asked: Does Jerry Seinfeld have the beginnings of Parkinson's or some other affliction? His head is trembling.'

Others echoed the same concerns with one commenting: 'Take a close look. He has Parkinson's. Head shakes....'

Another asked: 'Am I seeing a Parkinson's remote with his head???'

A tremor or an uncontrollable movement is one of the most well-known signs of Parkinson's and can be the very first symptom to appear.

Parkinson's is the fastest-growing neurological condition in the world and there is currently no cure. However, knowing the symptoms of Parkinson's can lead to earlier diagnoses and access to treatments that improve patients' quality of life. 

Around 90,000 Americans and 18,000 Brits are diagnosed with the condition every year, with charities estimating that one in 37 people alive today will be diagnosed in their lifetime. 

Jerry has not addressed the comments.

DailyMail.com has contacted representatives for him for comment. 

During his appearance, Jerry reflected on his impressive career and spoke adoringly about his family life 

The comedian joined Graham to promote his upcoming film, Unfrosted.

During the interview he discussed his marriage to author Jessica Seinfeld, 52, with whom he has children Sascha, 23, Julian, 21, and Shepherd, 18.

'I was a very successful comedian,' he said. 'A comedian is an in one act. You think "I don’t need anyone." That’s what a comedian thinks. This is not a good partner. 

'Someone who doesn’t think they need anyone isn’t a good partner. This is why most comedians either fail at marriage or don’t even try it… it’s really not for us. I wanted to do it to see if I could do something I’m really not cut out for.

Speaking about his children, he added: 'Kids are the greatest show on earth, you just want to watch them live. And the entertainment value of watching them try to live is…

'The kids are very entertaining because they're primitive humans.'

Jerry's interview with Graham was filmed on March 27. 'Fun afternoon years in the works filming an upcoming episode with Jerry Seinfeld!' Graham had said at the time

Last week, Jerry aimed his ire at the politically correct 'extreme left', telling the New Yorker's David Remnick that oversensitivity has ruined comedy.

The Seinfeld star said that even though people crave comedic relief, they can't find it on TV.

Speaking on an episode of the New Yorker's Radio Hour, he said: 'Nothing really affects comedy. People always need it. They need it so badly and they don't get it.'

He also fondly remembered the days when people would get home and turn on the TV to watch comedies such as Cheers, M.A.S.H., or All in the Family.

Jerry apparently doesn't think any modern-day TV comedies compare to the 1970s and 1980s classics.

'Well, guess what? Where is it? Where is it? This is the result of the extreme left and P.C. c**p and people worrying so much about offending other people,' he added.
