Is Your Child’s Stomach Pain All in His Head We all know there are times that kids seem to complain (51) a stomach ache to get out of chores or going to school. Don’t be so sure that the pain they (52) is all in their minds. We’re learning more now about a condition (53) "functional abdominal pain" that is experienced by millions of kids every day. Like many teenagers, Kyle Brust makes it a point to do his homework: as (54) as he gets home. Unlike most, Kyle often did his with a terrible stomach ache. In fact, the (55) often started while he was at school, but getting help there was getting harder. "Some of my teachers wouldn’t let me go, because I’d asked so many times before and they thought I was trying to get out of (56) ." says Kyle. Kyle’s mom Marilyn says she couldn’t blame the (57) . After all, she’d taken him to the doctor several times herself, and even they couldn’t find anything (58) . "You know, you’re running the tests and nothing’s coming up. So, is it in his head, is he just an extremely stressful child It’s just frustrating (59) we’re not finding any answers. " says Marilyn. It turns out Kyle was suffering from a condition known (60) functional abdominal pain, that affects as many as one out of every ten kids in this country. Even (61) the cause of the pain may not be obvious, there are real consequences. "It really does hurt, and these kids really do suffer. " says Dr. Campo, MD at Nationwide Children’s Hospital. To help (62) , Campo is looking into a new approach. He’s conducting clinical trials of an antidepressant that changes the way the body handles a chemical called serotonin.

Sleep Sleep is part of a person’s daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you first drift off into slumber, your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing will slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves predominating for the first few minutes. This is called stage 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep, the slower your brain waves will be. Then about 40 to 60 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain waves will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep. You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids as if you were looking at something occurring in front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep period, your body will soon relax again, your breathing will grow slow and regular once more, and you will slip gently back from stage 1 to stage 4 sleep-only to rise once again to the surface of near consciousness some 80 minutes later. Every stage of sleep occur in cycles.
