Voice screening by means of recordings was conducted on 428 adults going through a series of tests at a multiphasic health-screening unit. Judgments of voice quality made by a trained listener were compared with judgments made by the participant. Laryngeal examinations were obtained on selected cases. Between 5 and 10% had some type of laryngeal or nasopharyngeal pathology that produced a deviant voice quality, indicating that a health-screening program which includes voice screening can identify a significant segment of the affected adult population early enough to prevent the development of more serious laryngeal lesions.
The clinical features of infantile aphasia include failure or delay in development of speech. When speech develops, it is frequently garbled. Hearing and intelligence may be normal although both are difficult to evaluate. Abnormal behavior may appear in these children simply because they lack normal opportunities to express themselves.
It is pointed out that many of the children of 4 to 5 years of age with delayed speech development may not simply be "deviates from the norm" but may actually suffer from mild degrees of aphasia. Earlier recognition and proper guidance for milder types of aphasia will depend ultimately on better definition of the pattern and rate of normal speech development.
At present, there apparently is little or no agreement either as to frequency or actuality of this syndrome in childhood. Unfortunately, mild cases are apt to be passed over and more severe ones are often tragically mislabeled as mental defectives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
