Dick Van Dyke's mystery illness has been solved, hopefully.
"It seems that my titanium dental implants are the cause of my head pounding," the 87-year-old favorite of stage, screen and television Tweeted Thursday
. "Has anyone else experienced this? Thanks for all your replies."
In late April, Van Dyke announced he was suffering
"fatigue and lack of sleep resulting from symptoms of a yet-to-be diagnosed neurological disorder."
As a result, he was forced to remain in his home in Malibu, with his wife Arlene
, and cancel a scheduled ceremony at Manhattan's 92nd Street Y, where he was to receive an award.
Added Van Dyke at the time, "My head bangs every time I lay down. I've had every test come back that I'm perfectly healthy. Anybody got any ideas?"
He also said, "It has been going on for 7 years. I've had every test you can think of, including an MRI and spinal tap."
