Reality-TV star Kim Zolciak-Biermann, a contestant this season on "Dancing with the Stars," remained hospitalized yesterday after suffering a transient ischemic attack.

"The last 24hrs have been whirlwind!" Zolciak-Biermann, 37, wrote on Instagram, captioning a photo of herself in a hospital gown in bed, attached to heart-monitoring sensors. "I landed yesterday morning from LAX (took the red eye right after DWTS) I got home and within minutes suffered a TIA (mini stroke) the left side of my body went completely numb and my speech was gone."

She wrote she was "extremely grateful" for her husband, Atlanta Falcons linebacker Kroy Biermann; her daughter, Brielle Biermann; her daughter's boyfriend, Slade Osborne; and makeup artist Niki Toney-Pressley.

In a TIA, blood flow to the brain is blocked or reduced, usually by a blood clot, but generally within 10 to 20 minutes blood flows properly again and symptoms, including numbness, trouble speaking, problems with balance and loss of face, arm or leg movement, disappear.

Former "Real Housewives of Atlanta" star Zolciak and her "DWTS" partner, Tony Dovolani, survived the first round of eliminations Monday on Season 21 of the ABC dance competition.
