'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.'

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.

In regards to his recent project, Seinfeld opened up about working on Unfrosted during an interview with CBS and discussed why he chose to make his feature directorial debut with the project.

'I thought, what would be the least work? The least work is for me to just tell the actor how to say it, instead of me telling the director, and then the director telling the actor,' he said.

The performer also spoke about how he chose to set up the film's comedic scenes. 

'You always wanna be in very serious places in comedy, 'cause it makes it easier to be funny. The more you're supposed to act right, when you act wrong, it's funny,' he stated.

Seinfeld went on to discuss how his work as a standup comedian inadvertently prepared him for his first time directing a feature film. 

'I'm a comedian, so I'm used to talking to people in an uncomfortable situation... That's not that different from a movie set. This is all awkward. And everyone's nervous,' he said.
