Each book in Lucent's Diseases and Disorders series explores a disease or disorder and the knowledge that has been accumulated (or discarded) by doctors through the years.
Speech disorders are many and varied. Most children, for example, go through phases of mispronouncing specific sounds.
Their speech errors are considered a problem when they continue past a certain age. A person with a hearing loss or who is deaf typically has difficulty acquiring speech and usually exhibits speech disorders related to the inability to hear. Sometimes injuries or illnesses such as stroke or Alzheimer's disease can cause a person who has always had normal speech to develop difficulties. The type of disorder and the age of onset usually determine whether a return to normal speech is possible.
