Apraxia is a neurological disorder that affects the ability to perform skilled movements and gestures despite having the motivation and physical capacity to execute them properly. Different from paralysis, apraxic patients have difficulty sequencing movements that were once easy to perform, such as dressing or eating. This inability arises due to the loss or inaccessibility of motor engrams or programs that guide these movements.
Causes of Apraxia
The disorder typically results from brain dysfunction, often affecting the parietal lobes. Causes can include stroke, head injuries, Alzheimer’s disease, and other neurological conditions.
Diagnosis and Treatment Options
Diagnosis involves ruling out conditions like muscle weakness and language comprehension issues. Treatment focuses on the underlying disorder and may include physical, speech, or occupational therapy. The prognosis varies depending on the underlying cause.
Effects of Apraxia on Occupational Performance
- Dressing Apraxia: A patient may incorrectly sequence the task of dressing, like placing underwear over pants.
- Mobility: Difficulties may arise in using mobility devices correctly, such as applying brakes to a wheelchair.
- Productivity: Challenges in employment or volunteering due to the need for task execution and sequencing.
Understanding Ideational vs. Conceptual Apraxia
Ideational Apraxia involves difficulty in sequencing tasks with multiple steps, while conceptual apraxia signifies a loss of understanding about the function of tools. Recognizing these nuances is crucial for effective intervention during therapy.
Differentiating Dyspraxia and Apraxia in Occupational Therapy
Dyspraxia involves a partial loss of motor coordination, which differs from apraxia’s complete loss of skilled movement capability. Both conditions require different therapeutic approaches and understanding within occupational therapy.
Types of Apraxia
- Ideomotor Apraxia: Inability to perform tasks on command but capable of automatic tasks.
- Constructional Disorder: Difficulty organizing items into a coherent structure, affecting tasks like model building or drawing.
- Dressing Apraxia: Involves challenges with spatial relations, causing errors in clothing orientation.

What is apraxia and how does it impact individuals?
Apraxia is a neurological disorder affecting the ability to perform skilled movements and gestures despite having the physical capacity to do so. It disrupts daily activities like dressing or eating due to challenges in sequencing movements.
What are the common causes of apraxia?
Apraxia is often caused by brain dysfunction, particularly affecting the parietal lobes. It can result from stroke, head injuries, Alzheimer’s disease, and other neurological conditions.
How is apraxia diagnosed and what treatment options exist?
Diagnosis involves excluding muscle weakness and language issues. Treatment focuses on the underlying cause and might include physical, speech, or occupational therapy. The prognosis depends on the cause.
How do ideational and conceptual apraxia differ?
Ideational apraxia involves difficulty sequencing multi-step tasks, while conceptual apraxia reflects a loss of understanding of tool functions. Differentiating these helps tailor therapy interventions effectively.
What strategies can help in preparing for the NBCOT® exam regarding apraxia?
Effective strategies include practicing task sequencing, organizing mock therapy sessions, using case studies to identify apraxia types, and engaging in multi-step task practice scenarios.
