Apraxia research paper

One century after Liepmann’s work on apraxia: where are we now?

Dyspraxia is a neurological disorder that impacts an individual's ability to plan and process motor tasks. Individuals with dyspraxia often have language problems, and sometimes a degree of difficulty with thought and perception. Dyspraxia, however, does not affect the person's intelligence, although it can cause learning problems in children. Developmental dyspraxia is an immaturity of the organization of movement. The brain does not process information in a way that allows for a full transmission of neural messages. Experts say that about 10 percent of people have some degree of dyspraxia, while approximately 2 percent have it severely.

Four out of every 5 children with evident dyspraxia are boys, although there is some debate as to whether dyspraxia might be under-diagnosed in girls. Symptoms tend to vary depending on the age of the individual. Later, we will look at each age group in more detail.

Some of the general symptoms of dyspraxia include:. A diagnosis of dyspraxia can be made by a clinical psychologist, an educational psychologist, a pediatrician, or an occupational therapist. Any parent who suspects their child may have dyspraxia should see their doctor. When carrying out an assessment, details will be required regarding the child's developmental history, intellectual ability, and gross and fine motor skills:.

The evaluator will need to know when and how developmental milestones, such as walking, crawling, and speaking were reached.

The child will be evaluated for balance, touch sensitivity, and variations on walking activities. Dyspraxia symptoms may vary depending on age. With that in mind, we will look at each age individually. Not every individual will have all of the symptoms outlined below:. There may also be a lack of awareness of potential dangers. Many experience moods swings and display erratic behavior. Researchers at the University of Bolton in England say that there is often a tendency to take things literally " the child may listen but not understand.

Scientists do not know what causes dyspraxia. Experts believe the person's nerve cells that control muscles motor neurons are not developing correctly. If motor neurons cannot form proper connections, for whatever reason, the brain will take much longer to process data.

A report from the University of Hull in England says that dyspraxia is " probably hereditary : several genes have been implicated. Often, there are many members within a family who are similarly affected. Although dyspraxia is not curable, with treatment, the individual can improve. However, the earlier a child is diagnosed, the better their prognosis will be. The following specialists most commonly treat people with dyspraxia:. An occupational therapist will evaluate how the child manages with everyday functions both at home and at school. They will then help the child develop skills specific to daily activities which they find difficult.

The speech-language pathologist will conduct an assessment of the child's speech, and then implement a treatment plan to help them to communicate more effectively. This involves improving the child's language, visual, movement, and auditory skills. The individual is set a series of tasks that gradually become more advanced - the aim is to challenge the child so that they improve, but not so much that it becomes frustrating or stressful. In a study published in the Journal of Alternative and Complementary Medicine , a team of Irish, British, and Swedish researchers evaluated the effects of equine therapy therapeutic horse-riding on a group of 40 children aged years with dyspraxia.

The children participated in six horse-riding sessions lasting 30 minutes each, as well as two minute audiovisual screening sessions. They found that riding therapy stimulated and improved the participants' cognition, mood, and gait parameters. The authors added that "the data also pointed to the potential value of an audiovisual approach to equine therapy. Experts say that active play - any play that involves physical activity - which can be outdoors or inside the home, helps improve motor activity.

Dyspraxia - Brain Foundation

The corpus callosum is a compact structure that connects the right and left cerebral hemispheres. Here we report the case of a 50 year old woman who presented with features of corpus callosum apraxia, initially mistaken as psychiatric symptom by her relatives. Computed tomography and magnetic resonance of brain confirmed the diagnosis of acute ischemic infarct in the body of the corpus callosum.

Isolated stroke involving the corpus callosum is rarely reported in literature and is a diagnostic challenge due to atypical clinical features.

Introduction Corpus callosum contains densely packed white matter tracts essential for coordination and integration of the two sides of brain. Case report A 50 year old woman presented with a history of abrupt onset of numbness on the left side of her body. Figure 1. Computed tomography scan of the brain showing infarct in corpus callosum.

Discussion The corpus callosum contains the white matter bundle that connects the interhemispheric neurons and serves to connect the cortical and subcortical structures of the brain. Consent Written informed consent for publication of their clinical details and clinical images was obtained from the patient.

NOTE: it is important to ensure the information in square brackets after the title is included in this citation. Not Approved. VIEWS 0. The authors point out that focal damage to the corpus callosum is rare and may present a diagnostic challenge. I only partly agree, as damage to the corpus callosum is at least occasionally observed following ischemic stroke to one of the pericallosal arteries, though in this case the damage is often not confined to the corpus callosum, but also involves medial frontal cortex and cingulate cortex.

I also think that such injury presents only a diagnostic challenge when the examiner does not specifically focus on symptoms of callosal disconnection. The body and genu of the corpus callosum carry fibers connecting pre-motor and parietal cortices of the two cerebral hemispheres which are necessary for the coordination of bilateral actions. When reading this case report I was surprised to notice that the authors observed apraxia of the left hand, but did not examine callosal transfer by asking the patient to execute bilateral actions.

Besides alien hand syndrome, corpus callosum damage is known to result in diagonistic dyspraxia. Similarly to alien hand syndrome, this disorder suggests an impairment of voluntary control, and some patients report that their hand feels disobedient or has 'its own personality'. Such impairments appear sufficiently mysterious to be mistaken as psychiatric symptoms. The current case is interesting because of the isolated corpus callosum damage, but one would have wished a thorough examination of disconnection signs other than unilateral apraxia.
