“You could tell by the look that something isn’t right,” said Anderson, who compared her daughter’s behavior to Batman’s arch-nemesis. “It was almost as if she started to grind her teeth and then it was kind of a smile almost like the Joker – I don’t know how else to describe it,” Anderson said. NEW HYDE PARK, N.Y. – Doctors probed deep into the center of a 3-year-old girl’s brain to save her from her own laughter. Anastasia Lagalla’s uncontrollable laughter and seizures were part of an extremely rare condition that could have led to mental retardation, but doctors announced Thursday that surgery to remove a tumor causing the problem had been successful. “It’s like I have my little girl back,” said Ana’s mom, Jennifer Anderson of Ridge, N.Y., who beamed as she told reporters Thursday of her daughter’s recovery. “She’s doing amazing.” The laughing seizures began in May 2006, Anderson said, with only a few episodes a day. At first, Anderson and her husband, Peter Lagalla, agreed with the assessment of doctors that the tantrum-like symptoms were merely “terrible twos” behavior, but the frequency of the seizures grew to an alarming rate. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
