Puberty is a tough time for anybody. For Heroes star Greg Grunberg's son Jake, who has epilepsy, it presented its own unique challenges.
"Puberty screwed up levels of gauging whether his drugs were working or not. He was having more seizures," Grunberg tells PEOPLE. "Hundreds a day."
Luckily for Jake and his family, the 12-year-old was eligible for a brain surgery that turned out to be life-altering. "They removed the part of the brain that has the most epilepsy activity," Grunberg says of his son's operation. "Now Jake is only having a little tiny episode once every three weeks."
"To me," the proud father says, "that's a home run. We never thought that was possible."
With Jake's health improved, Grunberg has turned his attention to developing www.talkaboutit.org, a Web site that raises awareness about epilepsy, and has a social networking component for visitors.

He's played a CIA agent on Alias and now fights crime as a mind-reading police officer on Heroes. But Greg Grunberg says he's not the star in the family.
"Jake is my hero, he really is," Grunberg, 41, tells PEOPLE about his 12-year-old son, who has epilepsy. "He doesn't let anything stop him, and to deal with everything with your head up high, that to me is a true hero."
His son has been the inspiration behind his involvement in raising awareness about the neurological disorder, which includes raising funds for pediatric epilepsy research.
