Condition is no joke for teacher

A teacher's brain could spill out of her head if she laughs.

Carolyn Gibbons suffers from a rare condition called Arnold-Chiari Malformation, which causes her to have daily seizures and blurred vision, as well as crippling migraines.

But the 23 year-old who has been forced to quit teaching because of her condition has been warned if she laughs then her brain might move into the top of her spinal column and potentially kill her.

Carolyn who takes 50 pills to ease her pain said: "I'm living in a bubble of pain. The pressure could cause my brain to literally spill out of my head."
