Ideational apraxia is uncommon and involves disturbance in conception of object or gesture due to damage to which brain region?

• A. Left Parietal Lobe
• B. Right Parietal Lobe
• C. Left Frontal Lobe
• D. Cerebellum

Answer: (A)

Ideational apraxia occurs when the ability to form and organize the plan for using an object or carrying out a sequence of actions is lost. This planning capacity relies on the left parietal lobe, which stores knowledge about tools and skilled actions and links that knowledge to motor plans. When the left parietal region is damaged, a person may struggle to conceive the correct use of a tool or the proper steps to complete an activity, even though their movements themselves are possible and they understand the general goal.

That’s why the left parietal lobe is the best choice. Damage to the right parietal lobe tends to produce problems with spatial awareness rather than the conceptual planning of actions. The left frontal lobe is more often associated with initiating or programming specific movements (ideomotor aspects) rather than the initial conception of the action. The cerebellum affects coordination and timing, not the ideational understanding of how to perform a task.
