Ideomotor apraxia is best described as a disturbance in the performance of movements needed to use an object, make a gesture, or sequence movements, and it typically affects which type of movements?

• A. Automatic movements
• B. Voluntary movements
• C. Reflex movements
• D. Postural movements

Answer: (B)

Ideomotor apraxia mainly disrupts the ability to plan and carry out purposeful, goal-directed actions when they are demanded, such as using an object, making a gesture, or sequencing movements on cue. The key issue is with voluntary movements—when someone is asked to perform these actions or imitate them, it’s the deliberate, intentional aspect that fails. Automatic or habitual actions, in contrast, are often preserved because they can proceed without the same level of conscious planning. Reflex or postural movements aren’t the core problem here, since apraxia concerns skilled voluntary actions rather than automatic reflexes or posture maintenance.
