constructional apraxia
Impaired ability to construct or assemble objects, drawings, or designs despite adequate motor and sensory function.
Full Definition
Constructional apraxia is a neuropsychological deficit characterized by difficulty in constructing, assembling, or drawing two- or three-dimensional figures and objects. This condition affects the ability to organize spatial elements into coherent wholes, impacting tasks such as copying geometric figures, building with blocks, or drawing clock faces. Constructional apraxia can result from lesions in either hemisphere but presents differently: right-hemisphere damage typically causes visuospatial and attentional deficits, while left-hemisphere damage more commonly produces executive planning difficulties. Assessment typically involves copying tasks, block construction, and spontaneous drawing. This deficit significantly impacts daily living skills, occupational functioning, and rehabilitation potential.
Usage
Usage note: Specify hemisphere of damage as this affects the pattern of constructional difficulties observed.
