When a Large Left Hemisphere Stroke is All Right for Language, Praxis, and Visual Attention: A Case Report.

ABSTRACT:

Objectives

To describe a rare case of large left hemisphere (LH) middle cerebral artery (MCA) stroke with intact language, praxis, visuospatial cognition, and attention, suggesting lateralization of all these functions to the intact right hemisphere (RH).

Methods
