Apraxia is a neurological disorder that affects a person's ability to perform purposeful movements, despite having the physical ability to do so. It is estimated that the prevalence of apraxia varies depending on the specific type and population being studied.
In children: Childhood apraxia of speech (CAS) is a type of apraxia that affects speech production. The prevalence of CAS is estimated to be around 1-2 children per 1,000, making it a relatively rare condition.
In adults: Apraxia can also occur in adults, particularly after a stroke or brain injury. The prevalence of apraxia in adults is more difficult to determine due to the wide range of causes and the lack of standardized diagnostic criteria. However, it is estimated that apraxia affects approximately 30-50% of stroke survivors.
It is important to note that these prevalence rates are approximate and can vary depending on the specific population and diagnostic criteria used. Early diagnosis and intervention are crucial in managing apraxia and improving functional outcomes.
