It is an effect of neurological disease. It makes people powerless to carry out everyday movements and signals. For example, a person with apraxia may be unable to tie their shoelaces or button up a shirt. People with apraxia of speech find it challenging to talk and express themselves through speech.
Share on PinterestHead trauma, stroke, and dementia are all possible causes of apraxia. Apraxia happens when certain regions of the cerebral hemispheres in the brain do not work properly. This dysfunction may occur if a lesion in the brain forms across the neural pathways that store memories of learned movements. A person with apraxia may be unable to access this information. Apraxia can happen due to a head injury or disease that affects the brain, such as:
corticobasal ganglionic degeneration
Apraxia is more common in older adults due to the higher incidence of neurological diseases, such as stroke and dementia, among this population. If people have apraxia due to swelling from a stroke, it might improve within a few week. Apraxia can also be a genetic disorder. If an infant has apraxia at birth, it may be due to problems involving the central nervous system.
The main symptom of apraxia is an inability to carry out simple movements, even though a person with apraxia has full use of their body and understands commands to move. People with apraxia may find it difficult to control or coordinate movements voluntarily. These individuals may also have brain damage that causes aphasia, a language impairment that reduces the ability to understand or use words correctly.
Different types of apraxia affect the body in slightly different ways: People with limb-kinetic apraxia are unable to use a finger, arm, or leg to make precise and coordinated movements. Although people with limb-kinetic apraxia may understand how to use a tool, such as a screwdriver, and may have used it in the past, they are now unable to carry out the same movement.
People with ideomotor apraxia are unable to follow a verbal command to copy the movements of others or follow suggestions for movements.
This form of apraxia is similar to ideomotor apraxia. People with conceptual apraxia are also unable to perform tasks that involve more than one step.
People with ideational apraxia are unable to plan a particular movement. They may find it hard to follow a sequence of movements, such as getting dressed or bathing.
People with buccofacial apraxia, or facial-oral apraxia, are unable to make movements with the face and lips on command.
People with constructional apraxia are unable to copy, draw, or construct basic diagrams or figures.
Oculomotor apraxia affects the eyes. People with this type of apraxia have difficulty making eye movements on command.
People with verbal or oral apraxia find it challenging to make the movements necessary for speech. They may have problems producing sounds and understanding rhythms of speech.
