Stroke’s no joke. But a Las Vegas doctor, who has a side job as a singer/composer, has created a hysterical new music video — called "Can't Feel My Face" — that aims to raise awareness of stroke symptoms.

Dr. Zubin Damania — AKA ZDoggMD — says he produced the video after a recent University of California-Los Angeles study showed 73 percent of people under 45 wouldn't know to seek medical care immediately if they had symptoms of a stroke.

“Strokes aren’t funny,” Damania says, in a Website blog post with the video.

“They cause untold suffering, disability, and death on a massive scale each year. Having personally lost both of my grandmothers to stroke at relatively young ages, this issue is deadly serious to me. Apart from preventing a stroke in the first place (that is, controlling diabetes, hypertension, obesity, high cholesterol, stress, heart arrhythmias, etc.), recognizing the signs of stroke early is the best hope of saving brain cells — and lives.”

“Can’t Feel My Face” includes cameos from a variety of healthcare workers posing as music club attendees — nurses, stroke coordinators, and EMS students.

It also spotlights a quick way to way to remember the signs of stroke — the acronym FAST, short for Face-Arms-Speech-Time. Stroke victims often have facial drooping on one side, may be unable to lift up both arms, typically have slurred or garbled speech, and should waste no time when calling emergency services.

Other symptoms can include numbness or weakness on one side of the body, confusion, trouble seeing on one side, loss of coordination or balance, or severe headache.
