Also known as CAS, childhood apraxia of speech is a motor speech disorder that can sometimes accompany autism. Children with apraxia often exhibit different symptoms since the brain of each child has different strengths and weaknesses that correspond to movements made by the mouth, lips, jaw, and tongue.
Apraxia and autism are both disorders that involve speech and communication, but they are not the same disorder. One recent scientific study suggests that as much as 65% of children with autism have speech apraxia.
CAS is sometimes called verbal dyspraxia or developmental apraxia. Even though the word “developmental" is used, CAS is not a problem that children outgrow. A child with CAS will not learn speech sounds in typical order and will not make progress without treatment.
They do not usually have the accompanying learning disabilities associated with autism, but they may have specific learning difficulties. These may include dyslexia and dyspraxia or other conditions such as attention deficit hyperactivity disorder (ADHD) and epilepsy.
Some studies suggest that, 1-2 children in every 1,000 children have developmental verbal dyspraxia.
However, this does not mean that they are the same. Fundamentally, autism is a disorder that affects socialization and communication, while dyspraxia affects motor skills and physical coordination. While coinciding symptoms aren't uncommon, the two are considered distinct disorders.
Dyspraxia is most commonly caused by stroke or acquired brain injury. There are 2 types of Dyspraxia: (1) Oral dyspraxia– difficulty with non-verbal tasks - when asked to do so (E.g. please poke out your tongue), however the person can perform non-verbal tasks successfully and automatically (E.g. licking an ice cream).
being slow to pick up new skills – they need encouragement and repetition to help them learn. difficulty making friends – they may avoid taking part in team games and may be bullied for being "different" or clumsy. behaviour problems – often stemming from a child's frustration with their symptoms. low self-esteem.
Does dyspraxia/DCD run in families? Dyspraxia/DCD seems to run in families in some cases, but to date, no specific gene has been identified. It is likely that there are many different causes of dyspraxia/DCD, and genetics may be one.
Tend to get stressed, depressed and anxious easily. May have difficulty sleeping. Prone to low self-esteem, emotional outbursts, phobias, fears, obsessions, compulsions and addictive behaviour.
Dyspraxia does not affect your intelligence. It can affect your co-ordination skills – such as tasks requiring balance, playing sports or learning to drive a car.
Children with verbal dyspraxia will need to see a speech and language therapist for treatment and progress is often quite slow. They will need regular, direct therapy. Children with verbal dyspraxia might use different ways to communicate e.g. signing or special equipment that can be programmed to talk for them.
Dyspraxia does not affect a person's IQ, but they may often have to navigate a mind which can be unorganized, meaning they are usually very intelligent people. Navigating around these barriers results in creating strategies to overcome problems really well.
A person with verbal dyspraxia has difficulty placing muscles in the correct position to produce speech. The muscles have not been damaged. The messages from the brain that tell the muscles what to do have been affected. Dyspraxia does not affect a person's ability to understand.
Difficulty moving smoothly from one sound, syllable or word to another. Groping movements with the jaw, lips or tongue to make the correct movement for speech sounds. Vowel distortions, such as attempting to use the correct vowel, but saying it incorrectly.
Daniel Radcliffe (Actor)
Best known for his titular role in the Harry Potter films, Daniel revealed that he had a mild form of dyspraxia in 2008 in an interview for his Broadway debut in Equus. He was unsuccessful at school and 'he sometimes still has trouble tying his shoelaces.
While they do not get worse over time, their challenges may become more apparent with increasing academic demands. They have to work harder and/or differently than their peers to achieve the same goals. Despite their difficulties, pupils with dyspraxia can and do learn to perform some motor tasks quite well.
being born prematurely, before the 37th week of pregnancy. being born with a low birth weight. having a family history of DCD, although it is not clear exactly which genes may be involved in the condition. the mother drinking alcohol or taking illegal drugs while pregnant.
generally it impacts fine motor skills (e.g. holding a pencil) and/or gross motor skills (e.g. riding a bicycle). It can also impact the ability to organise yourself, remember information and control actions. processing differences. They may be sensory avoidant e.g. leaving a room when noises are too loud for them.
Dyspraxic people tend to be good at bold 'big picture' thinking, pattern-spotting and inferential reasoning. Due to the challenges they experience they are often resourceful, persistent, and determined problem-solvers. Likewise, with the right support in place they are very reliable and hard working.
The exact cause of development disorder dyspraxia is unknown. However, it is speculated that injuries to the brain may result in dyspraxia. Injuries may occur while the baby is still within the womb. Sometimes it could be due to adequate development of the brain cells or due to lack of oxygen during birth.
Developmental Coordination Disorder (DCD), also known as dyspraxia, is a common disorder affecting fine and/or gross motor coordination in children and adults.
While ADHD is a learning difficulty that often affects attention, behavior or both, dyspraxia has to do with fine motor skills, language and planning abilities and is not always classed as a learning difficulty.
