As we age, our sleep patterns change. We've all heard the complaints: "I wake up in the middle of the night and can't get back to sleep!"
Some sleep experts estimate that as many as 40 percent of older adults suffer sleeping problems such as sleep apnea and insomnia. Now, researchers have found a link between disrupted sleep and cognitive decline.
Miranda Kelly, a 14-year-old from Sykesville, Md., says she's been sleepwalking since she was 6 or 7. The first time, she says, "I woke up on the couch on a school day. And I'd gone to bed in my bed."
Since that first episode, Kelly now sleepwalks every couple of months. "I wake up in weird places, randomly. I have once woken up in the kitchen, and on the floor of the bathroom wrapped in my sheet," she says.
