Dyspraxia (from Greek "δυσ-" dys- (bad, pathological deviation from the norm) and "πραττειν" (prattein) "to act") is a lifelong coordination and developmental disorder (developmental dyspraxia). The prevalence is 1.8-5% or, according to DSM-5, 5-8% for children aged 5-11 years; 1.8% of 7-year-olds have a severe disorder, 3% a probable disorder. Boys are more likely to be affected in a ratio of between 2:1 to 7:1 Ripley, Daines and Barrett say that "developed dyspraxia makes it difficult to let one's own body do what we want it to do when we want it to do it" and that these difficulties can be considered significant if they interfere with the range of normal activities expected of children of a certain age.
Symptoms and complaints
Another name "clumsy child syndrome" indicates the gross and fine motor difficulties of the patient. For example, choreatic movements are noticeable when the limbs are held free and there is difficulty in moving both arms and legs at the same time. The affected person finds it difficult to move his limbs as he wishes. The disorder affects both the ability to plan action and the learning of action, i.e. the memory function in the brain for action.
Types of dyspraxic disorder
There are two types of dyspraxic disorder: it can affect direct action or it can affect theoretical reflection.
