Ideational agraphia: a single case study.

D M Baxter, E K Warrington

Journal of Neurology, Neurosurgery, and Psychiatry

|April 1, 1986

Summary

This summary is machine-generated.

This case study reveals a unique writing impairment, "ideational agraphia," where patients struggle to initiate writing despite intact copying skills. This suggests difficulties in accessing motor writing programs.

Background:

Investigating the complex mechanisms underlying writing and praxic skills.
Examining selective impairments in skilled motor tasks.

Observation:

A case study of a patient with selective difficulty in writing letters and words.
Preserved ability to copy letters and words, indicating intact visual-motor function.

Findings:

Identification of a novel condition termed "ideational agraphia," characterized by impaired writing initiation.
Hypothesized difficulty in accessing correct motor programs or sequences for writing.
Analogy drawn to the syndrome of ideational apraxia, linking to motor planning deficits.

Implications:
