Purpose: Motor speech characteristics of children with Down syndrome (DS) have historically been viewed as either Childhood Dysarthria (CD) or, more infrequently, as Childhood Apraxia of Speech (CAS).
Is dysarthria common in Down syndrome?
The speech, prosody, and voice signs of individuals with Down syndrome classified as CD were most consistent with ataxic dysarthria.
Do people with Down syndrome have speech impediments?
There is a general consensus that speech difficulties are common in individuals with Down syndrome and that these consist of a complex interweave of phonological and motor-speech delay and deviance.
How does Down syndrome affect voice?
The voice quality of individuals with Down Syndrome (DS) is generally described as husky, monotonous and raucous. On the other hand, the voice of DS children is characterized by breathiness, roughness, and nasality and is typically low pitched.
What are three physical issues that can lead to speech problems for people with Down syndrome?
Children with Down syndrome often have anatomical and physiological differences in the mouth and throat region that affect feeding, swallowing, and oral motor skills. 2These differences include low facial muscle tone, a small oral cavity with a relatively large tongue, and a narrow, high-arched palate.
What are symptoms of dysarthria?
- Slurred speech.
- Slow speech.
- Inability to speak louder than a whisper or speaking too loudly.
- Rapid speech that is difficult to understand.
- Nasal, raspy or strained voice.
- Uneven or abnormal speech rhythm.
- Uneven speech volume.
- Monotone speech.
What affects dysarthria?
Dysarthria is a motor speech disorder in which the muscles that are used to produce speech are damaged, paralyzed, or weakened. The person with dysarthria cannot control their tongue or voice box and may slur words. There are strategies to improve communication.
Do all Down syndrome babies have speech problems?
In fact, nearly all individuals with Down syndrome may be difficult to understand at least some of the time (Kumin, 1994). The phonological factors described above, in addition to factors such as apraxia of speech, dysarthria, and voice quality, may impact speech intelligibility.
Why do people with Down syndrome have different voices?
They found that the frequencies were normal – or slightly above normal: the slight difference probably being accounted for by the fact that people with Down syndrome tend to be physically smaller than the general population. Basically then, the larynxes of people with Down syndrome are producing a normal vibration.
Why do people with Down syndrome struggle with speech?
Because of this visual strength, abstract concepts such as grammar, verb tenses, word roots, suffixes and prefixes are more difficult areas. Children with Down syndrome frequently have difficulty with grammar, tenses and word endings and use shorter sentences to communicate.
Why do Down syndrome people stutter?
People with Down’s syndrome are born with an extra chromosome as a result of a genetic accident before or around the time of conception (1). This results in a certain degree of learning difficulty which can affect the ability to understand and produce speech and language.
How does Down syndrome affect articulation?
Dodd and Thompson clearly show that children with Down syndrome are inconsistent in speech production, with over half of all words produced being pronounced differently on repeated productions. Variability is also reported in the articulation of fricatives by young people with Down syndrome.
What is developmental apraxia of speech?
Overview. Childhood apraxia of speech (CAS) is an uncommon speech disorder in which a child has difficulty making accurate movements when speaking. In CAS , the brain struggles to develop plans for speech movement.
What is life expectancy for Down syndrome?
Today the average lifespan of a person with Down syndrome is approximately 60 years. As recently as 1983, the average lifespan of a person with Down syndrome was 25 years. The dramatic increase to 60 years is largely due to the end of the inhumane practice of institutionalizing people with Down syndrome.
