CBS news reporter Serene Branson was taken to the hospital last night after showing signs of a possible stroke. While reporting on the Grammys from LA, she became unable to pronounce words properly, releasing a string of unintelligible sounds before the camera cut away. Signs of a stroke include the inability to speak, as well as face numbness, weakness on one side of the body, and double vision.

Delaware Attorney General (and son of VP Joe Biden) Beau Biden, 41, checked himself into a hospital yesterday morning with a headache. The cause was mild stroke, doctors say, and he is expected to recover fully.

Vice president Biden is known to have had an aneurysm in 1988 at the age of 45. It's not clear if family history played a role in Beau's stroke.

Each year 700,000 people suffer a stroke. Five hundred thousand of these strokes are first occurrences, while the rest are repeat strokes. According to ABC News, approximately 10 to 15 percent of strokes  occur in people under 45.

A glass of red wine a day could keep the stroke away -- at least in mice, according to a new study published in the journal Experimental Neurology.

Researchers at the John Hopkins Medical Institute induced stroke in mice by cutting off blood supply, and found that those fed a modest dose of resveratrol -- a compound found in the skin and seeds of grapes -- two hours beforehand suffered significantly less brain damage than mice not given the compound.

"Resveratrol itself may not be shielding brain cells from free radical damage directly but instead, resveratrol, and its metabolites, may be prompting the cells to defend themselves," study leader Sylvain Doré said in a press release from Johns Hopkins.

You've probably heard by now that Poison frontman and reality TV star Bret Michaels was admitted to the hospital on April 22 with complaints of a severe headache. Doctors found bleeding in his brainstem and Michaels was diagnosed with subarachnoid hemorrhage, or bleeding in the area between the brain and the thin tissues that cover the brain.

The 47-year-old singer, who has diabetes, had an emergency appendectomy a couple weeks ago; it's not known whether the diabetes or the recent surgery is related to his current condition. According to the LA Times, Michaels is under 24-hour surveillance as doctors work to find the source of the bleeding.
