Answer 1

Apraxia is the condition described in the question, referring to the inability to perform motor responses on verbal command. It can be caused by various factors such as stroke, brain damage, or degenerative disorders.

Step-by-step explanation:

The condition described in the question is called apraxia, which refers to the inability to perform motor responses on verbal command while being able to do so spontaneously. Apraxia is a neurological disorder that can affect different areas of the brain, resulting in difficulty carrying out purposeful movements even though there is no muscle weakness or paralysis.

For example, a patient with apraxia may be unable to pinch their nose when asked, but can do so spontaneously without any verbal command.

Apraxia can be caused by various factors such as stroke, brain damage, or degenerative disorders. It is often diagnosed through clinical observation and neurological assessments.
