Which apraxia is characterized by an inability to translate intention into action, such as pantomiming on command, often with nonfluent aphasia?

Explanation:
The key idea here is how the brain turns a deliberate plan into an actual movement. When someone understands what to do and can use an object in real life, but cannot translate that plan into a gesture on command or when asked to imitate a movement, that points to ideomotor apraxia. In this pattern, comprehension is intact and automatic actions can sometimes be preserved, but deliberate pantomiming or miming a tool becomes broken. This condition often sits with left-hemisphere damage and can be seen alongside nonfluent aphasia, reflecting shared disruption in the networks that link intention with motor execution. Ideational apraxia, by contrast, would involve difficulty conceptualizing the task or the proper use of objects, leading to errors in sequencing or using items incorrectly, not just trouble with pantomiming a gesture. Limb apraxia is a broader term for praxis disorders of the limbs, but the specific deficit described—trouble translating intention into a motor gesture on command—best fits ideomotor apraxia.
