    Mayo Clinic Minute: Restless legs syndrome in kids

Does your child toss and turn at night, and have trouble sleeping? It might be restless legs syndrome.

Dr. Suresh Kotagal, a Mayo Clinic pediatric neurologist and sleep specialist, says some young patients describe it as feeling like bugs are crawling on their legs while lying in bed, and moving their legs is the only relief. The end result is a lack of good, quality sleep, which can have negative side effects at home or in school.

"Sometimes kids will say that 'I feel like I have to kick my legs' or 'I feel like I have to move my legs to get comfortable,'" says Dr. Kotagal.

That's restless legs syndrome, a genetic disorder that Dr. Kotagal says is more common in children than you might think. Studies show that 1 in 50 kids have the condition, a discomfort that can prevent a child from falling asleep and repeatedly wake a child during sleep.

"They are tired in the daytime and frequently have troubles with attention span," says Dr. Kotagal.

It often can be related to low levels of iron, which helps make dopamine, a chemical that helps in neurotransmission in the brain and learning.

"So if we don't have enough dopamine, one is likely to have disturbed sleep," he says.

Dr. Kotagal says children with restless legs syndrome may go undiagnosed because there is a lack of awareness of the condition, and it can be attributed to attention deficit hyperactivity disorder instead. He says the first step is to talk about sleep disorders with your primary care provider or pediatrician.
