Causes

Apraxia is caused by diseases or damage in the brain, such as:

• Stroke
• Brain tumor
• Brain injury
• Infection
• Brain disease, such as:
  • Alzheimer’s disease
  • Frontotemporal dementia (a syndrome associated with shrinking of the frontal and temporal anterior portions of the brain)
  • Huntington’s disease
  • Corticobasal ganglionic degeneration (CBD)

Risk Factors

Apraxia may be due to stroke. It is important to know the risk factors for stroke such as:

• Increased age
• Prior stroke or cardiovascular disease
• Prior transient ischemic attack (TIA)
• High blood pressure
• High cholesterol
• Diabetes
• Smoking
• Dialysis (treatment that takes over the job of the kidneys when they fail)

Symptoms

Some of the common forms of apraxia and some of their symptoms include:

• Buccofacial or orofacial apraxia (common)—inability to make facial movements, such as winking, whistling, or sticking out tongue
• Constructional apraxia—inability to copy or draw simple figures or to make two- or three-dimensional forms
• Gait apraxia—difficulty walking, which can lead to an increased risk of falls
• Conceptual apraxia—inability to select or use tools or objects properly, inability to make complex movements at the same time and to do tasks in order
• Limb-kinetic apraxia—inability to make fine, exact movements with hands or fingers (eg, handling coins)
• Ideomotor apraxia—inability to copy movements or make signals, inability to do a function on command
• Dressing apraxia—inability to dress oneself

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include:

• A neurological exam—You may be asked to:
  • Copy posture, movement, sequences
  • Draw shapes
  • Put together designs
  • Pick up or rotate coins
  • Select a tool (eg, a hammer) and demonstrate how to use it
  • Arrange movements in sequence
• Exam of muscles used in speech
• Evaluation of walking skills
• Your doctor may need pictures of your brain. This can be done with:
  • MRI scan
  • CT scan

If you are diagnosed with apraxia, you could also have aphasia . Aphasia is a language disorder.

Treatment

Your treatment depends on what kind of apraxia you have. Families should ask about individualized treatment programs such as:

• Physical therapy
• Occupational therapy
• Speech therapy
• Cognitive rehabilitation

It is also important to treat the cause of the apraxia.

Prevention

It may be difficult to prevent this condition. It is strongly linked to stroke. Following steps to prevent stroke may help. Some of these steps include:

• Exercise regularly.
• Eat a healthy diet .
• Quit smoking and limit how much alcohol you drink.
• Check your blood pressure often.
