Information on speech and language disorders in children and adolescents including causes, diagnosis, treatment and useful information for parents.
Speech and language disorders refer to problems in
communication and related areas such as oral motor
function. These delays and disorders range from simple
sound substitutions to the inability to understand or
use language or use the oral-motor mechanism for
functional speech and feeding. Some causes of speech and
language disorders include hearing loss, neurological
disorders, brain injury, mental retardation, drug abuse,
physical impairments such as cleft lip or palate, and
vocal abuse or misuse. Frequently, however, the cause is
unknown.
More than one million of the students served in the
public schools’ special education programs in the
2000-2001 school year were categorized as having a
speech or language impairment. This estimate does not
include children who have speech/language problems
secondary to other conditions such as deafness. Language
disorders may be related to other disabilities such as
mental retardation, autism, or cerebral palsy. It is
estimated that communication disorders (including
speech, language, and hearing disorders) affect one of
every 10 people in the United States.
A child's communication is considered delayed when the
child is noticeably behind his or her peers in the
acquisition of speech and/or language skills. Sometimes
a child will have greater receptive (understanding) than
expressive (speaking) language skills, but this is not
always the case.
Speech disorders refer to difficulties producing speech
sounds or problems with voice quality. They might be
characterized by an interruption in the flow or rhythm
of speech, such as stuttering, which is called
dysfluency. Speech disorders may be problems with the
way sounds are formed, called articulation or
phonological disorders, or they may be difficulties with
the pitch, volume or quality of the voice. There may be
a combination of several problems. People with speech
disorders have trouble using some speech sounds, which
can also be a symptom of a delay. They may say "see"
when they mean "ski" or they may have trouble using
other sounds like "l" or "r." Listeners may have trouble
understanding what someone with a speech disorder is
trying to say. People with voice disorders may have
trouble with the way their voices sound.
A language disorder is an impairment in the ability to
understand and/or use words in context, both verbally
and nonverbally. Some characteristics of language
disorders include improper use of words and their
meanings, inability to express ideas, inappropriate
grammatical patterns, reduced vocabulary and inability
to follow directions. One or a combination of these
characteristics may occur in children who are affected
by language learning disabilities or developmental
language delay. Children may hear or see a word but not
be able to understand its meaning. They may have trouble
getting others to understand what they are trying to
communicate.

What Is Meant by "Communication Disorders"?The term communication disorders encompasses
a wide variety of problems in language, speech,
and hearing. Speech and language impairments
include articulation problems, voice disorders,
fluency problems (such as stuttering), aphasia
(difficulty in using words, usually as a result
of a brain injury), and delays in speech and/or
language. Speech and language delays may be due
to many factors, including environmental factors
or hearing loss. |
How Many Children Have Communication Disorders?The overall estimate for speech and language
disorders is widely agreed to be 5% of
school-aged children. This figure includes voice
disorders (3%) and stuttering (1%). The
incidence of elementary school children who
exhibit delayed phonological (articulation)
development is 2% to 3%, although the percentage
decreases steadily with age. |
