Family battles rare disorder that affects 200 children worldwide.

Four-year-old twin girls are fighting for their lives and their memories due to Niemann-Pick Disease--otherwise known as "Childhood Alzheimer's." It's a rare disorder that damages internal organs, causes early onset dementia, and is inevitably fatal.

Never heard of it? Neither had we. Pediatrician and friend of Mom•Logic Dr. Gwenn says, "In Niemann-Pick Type C, the body can't break down cholesterol, so it ends up in places that it shouldn't--like the brain. With a buildup of cholesterol in the brain, the child will develop symptoms similar to Alzheimer's over time."

How worried should Moms be? "This is so rare that most Moms shouldn't worry," Dr. Gwenn says. But if anyone else in your family has this condition or you belong to one of the high-risk groups, then she recommends seeking genetic counseling and testing.
