“This is a major medical problem that can lead to a deadly stroke!” said New York City internist Dr. Stuart Fischer.

Howie has also suffered from ADHD, OCD, anxiety and depression, and sparred with fellow “AGT” judges Howard Stern and Simon Cowell.

Both judges privately lobbied behind the scenes to have Howie dumped from the show, according to an “AGT” insider.

“That kind of anxiety can be dangerous for someone with this condition,” said Fischer.
