What is defined as the inability to carry out motor activities?

• A. Apraxia
• B. Dysarthria
• C. Aphasia
• D. Agnosia

Answer: (A)

Apraxia is a motor planning problem, where a person cannot perform learned, purposeful movements even though they have the desire, strength, and sensory ability to do so and understand the task. The issue isn’t weak muscles or a language problem. Strength would be intact, and comprehension, sensation, and even automatic movements can be preserved in many cases. This distinguishes apraxia from other conditions: dysarthria involves slurred or slow speech due to weak or uncoordinated speech muscles; aphasia is a language processing deficit; and agnosia is a failure to recognize objects despite normal sensation. In apraxia, the challenge is coordinating the correct sequence and execution of movements to carry out a goal.
