What type of dysarthria is associated with Down syndrome?

Children with Down syndrome who have motor speech disorder characteristics have historically been diagnosed as having childhood dysarthria.

Do people with Down syndrome have difficulty speaking?

Speech intelligibility (speech that can be easily understood) is one of the most difficult areas for people with Down syndrome at all ages. Many children have difficulty with the strength, timing and coordination of muscle movements for speech.

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 the characteristics of dysarthria?

Dysarthria refers to a group of neurogenic speech disorders characterized by “abnormalities in the strength, speed, range, steadiness, tone, or accuracy of movements required for breathing, phonatory, resonatory, articulatory, or prosodic aspects of speech production” (Duffy, 2013, p. 4).

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.

What is childhood dysarthria?

Children with dysarthria often have shallow, irregular breathing which creates difficulties in generating sufficient breath to support speech. They have low pitched, breathy or harsh voices, nasalised speech and very poor pronunciation. Together, these difficulties make the children’s speech difficult to understand.

What are three physical issues that can lead to speech problems for people with Down syndrome?

Children with Down Syndrome commonly experience feeding, swallowing and speech difficulties due to anatomical and physiological differences in their mouth area. These differences include a high arched palate, small upper jaw as well as low muscle tone in the tongue and weak oral muscles.

At what age do Down syndrome children speak?

Typically, these children have a much harder time learning to talk (expressive language) than with understanding what they hear (receptive language). On average, children with Down syndrome start using words around 16 months of age—about 6 months later than other children.

Do Down syndrome babies talk?

Can you fix dysarthria?

Treating the underlying cause of your dysarthria may improve your speech. You may also need speech therapy. For dysarthria caused by prescription medications, changing or discontinuing the medications may help.

How does dysarthria affect your ability to speak?

These abnormalities are due to one or more sensorimotor problems—including weakness or paralysis, incoordination, involuntary movements, or excessive, reduced, or variable muscle tone (Duffy, 2013). Dysarthria can adversely affect intelligibility of speech, naturalness of speech, or both.

How is hyperkinetic dysarthria related to CNS disease?

• The diversity of lesion associated with hyperkinetic dysarthria (and movement disorder in general) reflects the diversity of abnormal movements that may occur in CNS disease and our limited understanding of their anatomy and pathophysiology. 4.

Is there a prevalence of dysarthria in adults?

Estimates of the prevalence of dysarthria associated with some common neurologic conditions are as follows:

How many people with amyotrophic lateral sclerosis have dysarthria?

Amyotrophic lateral sclerosis: Dysarthria can be observed as an initial sign in up to 30% of individuals with amyotrophic lateral sclerosis, with almost all individuals developing dysarthria in later stages (Chen & Garrett, 2005; da Costa Franceschini & Mourão, 2015; Traynor et al., 2000).
