When a person is unable to produce speech sounds correctly or fluently, or has problems with his or her voice, then he or she has a speech disorder. Difficulties pronouncing sounds, or articulation disorders, and stuttering are examples of speech disorders.
What is childhood apraxia of speech?
Childhood apraxia of speech (CAS) is a motor speech disorder. Children with CAS have problems saying sounds, syllables, and words. This is not because of muscle weakness or paralysis. The brain has problems planning to move the body parts (e.g., lips, jaw, tongue) needed for speech. The child knows what he or she wants to say, but his/her brain has difficulty coordinating the muscle movements necessary to say those words.
What are speech sound disorders?
Most children make some mistakes as they learn to say new words. A speech sound disorder occurs when mistakes continue past a certain age. Every sound has a different range of ages when the child should make the sound correctly. Speech sound disorders include problems with articulation(making sounds) and phonological processes(sound patterns).
What is dysarthria?
Dysarthria is a motor speech disorder. The muscles of the mouth, face, and respiratory system may become weak, move slowly, or not move at all after a stroke or other brain injury. The type and severity of dysarthria depend on which area of the nervous system is affected.
Some causes of dysarthria include stroke, head injury, cerebral palsy, and muscular dystrophy. Both children and adults can have dysarthria.
What is stuttering?
Stuttering affects the fluency of speech. It begins during childhood and, in some cases, lasts throughout life. The disorder is characterized by disruptions in the production of speech sounds, also called “dysfluencies.” Most people produce brief dysfluencies from time to time. For instance, some words are repeated and others are preceded by “um” or “uh.” Dysfluencies are not necessarily a problem; however, they can impede communication when a person produces too many of them.
In most cases, stuttering has an impact on at least some daily activities. The specific activities that a person finds challenging to perform vary across individuals. For some people, communication difficulties only happen during specific activities, for example, talking on the telephone or talking before large groups. For most others, however, communication difficulties occur across a number of activities at home, school, or work. Some people may limit their participation in certain activities. Such “participation restrictions” often occur because the person is concerned about how others might react to dysfluent speech. Other people may try to hide their dysfluent speech from others by rearranging the words in their sentence (circumlocution), pretending to forget what they wanted to say, or declining to speak. Other people may find that they are excluded from participating in certain activities because of stuttering. Clearly, the impact of stuttering on daily life can be affected by how the person and others react to the disorder.
What is a language-based learning disability?
Language-based learning disabilities are problems with age-appropriate reading, spelling, and/or writing. This disorder is not about how smart a person is. Most people diagnosed with learning disabilities have average to superior intelligence.
What are some signs or symptoms of a language-based learning disability?
Dyslexia has been used to refer to the specific learning problem of reading. The term language-based learning disability, or just learning disabilities, is better because of the relationship between spoken and written language. Many children with reading problems have spoken language problems.
The child with dyslexia has trouble almost exclusively with the written (or printed) word. The child who has dyslexia as part of a larger language learning disability has trouble with both the spoken and the written word. These problems may include difficulty with the following:
