FORT MYERS, Fla. - Psych meds are supposed to help conditions like depression, irritability, and memory problems, to name a few. One doctor says many of these kids don't need drugs, but instead they just need a good night's sleep.

"I want to be on Broadway," William Einbinder is an energetic young man, but one day his father could see a big difference psychologically.

"He'd come home from school in the afternoon, and fall asleep, which is not like him. He's a very outgoing kind of a kid, and also his grades started dropping," says Morgan Einbinder.

Even William could tell something was wrong, "I dropped from an A in math to a C."

So the family went together to see a doctor. " A lot of these disorders, a lot of these psychiatric disorders could be brought back to a sleeping issue at night," says Dr. Jose Colon.

Sometimes they are treated for depression, irritability and other disorders with spych meds when in fact it's a sleep disorder.

"If you've ever seen 13 kids, 1 of them is on a psych medication," says Dr. Colon.

Doctor Colon says sleep apnea can cause depression and other disorders that lead to children being placed on medication.

He says, "A lot of these disorders, a lot of these psychiatric disorders could be brought back to a sleeping issue at night."

Now William has been placed on a CPAP sleeping machine. It helps the airflow to give him a good night's rest and improve his quality of life.

With the new machine, his father says, "It's been night and day."
