— LOS ANGELES - When we think of migraines, we think of a bad headache, but there is another type of migraine that causes unusual symptoms in kids.
"As the days went by I just kept on throwing up, I got dehydrated, wouldn't eat, wouldn't drink," says Sarina McFarlane.
"I'll vomit up to about 40 times a day. That's just terrible, terrible. For being my age especially," says Olivia Brown.
Both Sarena and Olivia suffer from Cyclic Vomiting Syndrome, sometimes called Abdominal Migraine.
"In cyclic vomiting and abdominal migraine, as the word says you have disease in cycles or episodes and they will often occur with vomiting and nausea — but also abdominal pain, tiredness and occasionally other symptoms as well — including sometimes headache," explains Dr. Richard Boles, of Los Angeles.
Diagnosing the condition is tricky.
"Some of them have had over 100 episodes before somebody figured out what caused the trouble. And unfortunately probably most people out there with this condition still haven't recognized it for what it is," says Dr. Boles.
Dr. Boles has zeroed in on changes inside cells that might cause the problem.
"It's really the nerve cells that require the most energy and disease occurs at times of energy demand. This is a real disorder. There's a real physical cause that's not in your mind and treatments are usually, not always, but usually successful," he says.
Once diagnosed, treatments include prescription and over the counter medicines.
It's turned Sarina's life around.
"Everything seems a lot better. I'm back where I used to be," she says.
