Right-hemisphere lesions are most closely linked to which apraxia that involves difficulties with construction?

Constructional apraxia arises when right-hemisphere damage disrupts the ability to organize spatial information and integrate parts into a whole. This leads to difficulty constructing or copying complex figures, designs, or block configurations, even when basic motor skills are intact. The right parietal region specializes in visuospatial processing and spatial planning, so lesions there impair tasks that require assembling elements into a coherent construction. Dressing apraxia involves sequencing and coordinating dressing actions and is a different impairment; hemi-neglect is an attention deficit to the left side of space that can accompany right-hemisphere injury but isn’t the same as a construction problem; alien-hand syndrome is a disinhibited, involuntary movement phenomenon of a limb and not a construction deficit. Therefore, right-hemisphere damage most closely aligns with constructional apraxia.
