Spatial disorientation and the Dyke-Davidoff-Masson syndrome

A patient with Dyke-Davidoff-Masson Syndrome had a lifelong history of spatial disorientation and visual-spatial cognitive defects demonstrated by psychological tests.

We consider several explanations to account for the lack of compensation for these cognitive defects.
