What's the difference between dysarthria and apraxia?
People who live with apraxia have difficulty putting words together in the correct order or 'reaching' for the correct word while speaking. Dysarthria occurs when a patient's muscles do not coordinate together to produce speech. Weak or inefficient motor movements prevent dysarthria patients from speaking clearly.

Characteristics of childhood dysarthria manifests in each of the speech systems. Respiration is at a low intensity and speech is typically limited to short phrases because of ...
What is apraxia of speech?
Childhood apraxia of speech, also commonly seen in literature as CAS, is a motor speech disorder that is characterized by the child demonstrating difficulty of producing sounds, syllables, and words. This is not because of muscle weakness or paralysis but rather the child’s brain has problems planning to move the articulators needed for speech, such as lips, the mandible, and tongue. An individual with apraixa is aware or what they want to say but the brain is unable to plan muscle movements necessary to verbally communicate the individual’s ideas in a fluid manner.
How to tell if a child has apraxia?
Depending on age, there are different symptoms of a child with apraxia however, not all children diagnosed with CAS show the same signs. In a very young child, a child may not coo or babble as an infant, have late production of first words, demonstrate the inability to combine sounds, and have difficulty in eating. In an older child, there is a pattern of inconsistent sound errors, difficulty imitating speech, difficulty saying longer words, difficulty speaking while anxious, and may be seen groping while attempting to produce sounds to coordinate articulators such as lips, tongue, and the mandible. The child may be hard to understand or have choppy, monotonous speech (Caruso & Strand, 1999). Other issues noticed are delayed language development, difficulties with fine motor movement, coordination, hypersensitivity or hyposensitivity in the child’s mouth. An example of hypersensitivity or hyposensitivity in the mouth is the dislike of brushing teeth or eating crunchy foods. As with most speech problems, the child diagnosed may have trouble learning to read, spell, or write.
What is the treatment for dysarthria?
Sometimes, in severe cases, the use of an augmented communication device may be used. Treatment for dysarthria is based on severity; the level of severity and type of dysarthria forms the type of intervention used. As seen in mild to moderate cases, compensatory strategies are used to assist in the child’s function.
How to treat dysarthria in children?
The main goal for children diagnosed with dysarthria is to help them maximize their speech intelligibility. Other goals of treatment include slowing the rate of speech, improving respiratory support, strengthening muscles, increasing mouth, tongue, and lip movements, improving articulation, and family teaching (Caruso & Strand, 1999). Sometimes, in severe cases, the use of an augmented communication device may be used. Treatment for dysarthria is based on severity; the level of severity and type of dysarthria forms the type of intervention used. As seen in mild to moderate cases, compensatory strategies are used to assist in the child’s function. In severe dysarthria, alternate forms of communication tends to be necessary. It’s important for treatment to also incorporate the development of literacy and self-esteem (Walshe & Miller, 2011).
Why is hypernasality in articulation?
Hypernasality during resonation is because of weak movement of the soft palate which causes velopharyngeal incompetence. Articulation is distorted therefore imprecise consonants are produced. Imprecision in articulation is due to weakness and the in-coordination of the mandible, lips, and tongue.

Does dysarthria affect speech?
In dysarthria, there is a change in muscle tone, whereas there is no such change in apraxia. In apraxia, increased speech rate increases the intelligibility, whereas it has the opposing effect in dysarthria. Dyspraxia is associated with aspiration pneumonia as a complication, whereas dysarthria has no such relevance.
Is dysarthria consistent with dysarthria?
Apraxia is inconsistent, unpredictable, with islands of clear speech. Dysarthria is consistent, predictable and without islands of clear speech. All aspects of speech are affected in dysarthria, but only articulation is affected in apraxia. In dysarthria, there is a change in muscle tone, whereas there is no such change in apraxia.
Is dysarthria related to aspiration pneumonia?
Dyspraxia is associated with aspiration pneumonia as a complication, whereas dysarthria has no such relevance.

What is apraxia of speech?
Apraxia of speech (AOS)—also known as acquired apraxia of speech, verbal apraxia, or childhood apraxia of speech (CAS) when diagnosed in children—is a speech sound disorder. Someone with AOS has trouble saying what he or she wants to say correctly and consistently. AOS is a neurological disorder that affects the brain pathways involved in planning the sequence of movements involved in producing speech. The brain knows what it wants to say, but cannot properly plan and sequence the required speech sound movements.
What are the types and causes of apraxia of speech?
There are two main types of AOS: acquired apraxia of speech and childhood apraxia of speech.
How is apraxia of speech diagnosed?
Professionals known as speech-language pathologists play a key role in diagnosing and treating AOS. Because there is no single symptom or test that can be used to diagnose AOS, the person making the diagnosis generally looks for the presence of several of a group of symptoms, including those described earlier. Ruling out other conditions, such as muscle weakness or language production problems (e.g., aphasia), can help with the diagnostic process.
What research is being done to better understand apraxia of speech?
Researchers are searching for the causes of childhood AOS, including the possible role of abnormalities in the brain or other parts of the nervous system. They are also looking for genetic factors that may play a role in childhood AOS . Other research on childhood AOS aims to identify more specific criteria and new techniques to diagnose the disorder and to distinguish it from other communication disorders.
What is the role of speech pathologists?
Professionals known as speech-language pathologists play a key role in diagnosing and treating AOS. Because there is no single symptom or test that can be used to diagnose AOS, the person making the diagnosis generally looks for the presence of several of a group of symptoms, including those described earlier.
Why do words sound distorted?
Sounds, especially vowels, are often distorted. Because the speaker may not place the speech structures (e.g., tongue, jaw) quite in the right place, the sound comes out wrong. Longer or more complex words are usually harder to say than shorter or simpler words.
Can AOS cause speech problems?
It can be so mild that it causes trouble with only a few speech sounds or with pronunciation of words that have many syllables. In the most severe cases, someone with AOS might not be able to communicate effectively by speaking, and may need the help of alternative communication methods.
What is the cause of dysarthria in children?
Pediatric Dysarthria is a motor speech sound disorder resulting from neuromuscular weakness, paralysis or incoordination of the muscles needed to produce speech. The child’s speech may be slurred or distorted and the speech may range in intelligibility, based on the extent of neurological weakness. There are several types of pediatric dysarthria with varying characteristics. A child can have too much tone (spasticity) or too little low tone (hypotonicity). The fine motor movements that control respiration (breathing), phonation (movement of the vocal cords during speech), resonance (nasality) and articulation (lips, cheeks, throat, velum, and larynx) are affected. In addition to articulation errors of varying severity, children with dysarthria may experience prosodic (melody of speech) errors due to difficulty changing their pitch and loudness and slow rate of speech. Hypernasality (inappropriate air leakage into the nose during speech) is often noted in children with a dysarthric speech pattern.
What is the name of the disorder that causes speech to be distorted?
PEDIATRIC DYSARTHRIA. Pediatric Dysarthria is a motor speech sound disorder resulting from neuromuscular weakness, paralysis or incoordination of the muscles needed to produce speech.
What is the study of the sound system of a language?
Phonology is the study of the sound system of a language and it tells us the rules that govern how sounds fit together to form words. A child who has a phonological disorder has not learned how these sounds fit together to produce words. There errors follow a pattern and the more error patterns, the more unintelligible a child’s speech can appear. A phonological disorder is a language-based and not a motor-based speech sound disorder.
What is the disorder of speech execution?

How to treat articulation errors?
This may begin with auditory training to hear the correct sounds, techniques to achieve the correct sounds, production of the new sounds in isolation, then syllables, words, and phrases, and finally to generalization when the child can use their newly acquired sound mastery into situations outside of the therapy room.
Does motor learning increase speech?
Evidence supports that motor learning principles may be associated with increases in speech intelligibility, precision of articulatory movements and voice quality and clarity for children with moderate and severe dysarthria” (Pennington, L., Parker, N. K., et al. (2016).
