receptive language disorder A condition in which a child may have trouble understanding certain aspects of speech, such as a toddler who does not respond to his name or the child who cannot follow simple directions. While hearing is normal, these children cannot make sense of certain sounds, words, or sentences. Because using and understanding speech are strongly related, many children with receptive language disorders also have an expressive language disorder. some misuse of sounds, words, or grammar is a normal part of learning to speak. It is only when these problems persist that there is any cause for concern.
reflux, gastroesophageal (GERD) A disorder that occurs when stomach acid moves backward from the stomach into the esophagus. Gastroesophageal reflux disease (GERD) usually occurs because the muscular valve where the esophagus joins the stomach does not close properly. When the stomach acid comes into contact with the esophagus, it causes a burning sensation. Although many people experience heartburn occasionally, GERD occurs much more often and causes serious discomfort.
Eventually, the reflux of stomach acid damages the tissue lining the esophagus, causing inflammation and pain. No one knows for sure why people get GERD, but more than one million children in the United states have the condition.
