Question Constructional apraxia

Does constructional apraxia result from dominant or non dominant parietal lobe involvement? Kaplan behavioral science says non dominant but neuroscience says it's more common with dominant lobe involvement.
Or is there something I'm missing here?

My understanding is that if there is a lesion in any of the Premotor cortex it will lead to a Bilateral apraxia.
kindly correct me if I am wrong

In HY Neuro, it is mentioned that construction apraxia is seen in the destruction of inferior parietal lobule in nondominant hemisphere.

For example.If the patient draws only the right half of the clock, this condition is called hemineglect and the lesion is in the right inferior parietal lobule.

And that is middle cerebral artery territory, am I right?

I think so.
Because this part is lateral aspect of parietal lobe which should be supplied by MCA.



Lateral surface of left cerebral hemisphere, viewed from above. (Inferior parietal lobule visible at bottom left.)

Note that ACA supplies the frontal lobes and medial aspects of the parietal and occipital lobes.
