constructional apraxia
The inability to copy, draw, or construct two- or three-dimensional figures despite adequate motor and visual function.
Full Definition
Constructional apraxia is a neuropsychological syndrome characterized by impaired ability to copy drawings, construct geometric figures, or assemble objects despite intact basic motor skills and visual perception. Patients may struggle with tasks such as copying simple geometric shapes, drawing clock faces, or building with blocks. This condition typically results from parietal lobe dysfunction, particularly affecting visuospatial integration and motor planning. Constructional apraxia can significantly impact daily living activities requiring spatial coordination and planning.
Usage
Usage note: Often assessed using clock drawing, copying tasks, and block construction tests.
