Visuospatial stimulus-bound automatic writing behavior: a right hemispheric stroke syndrome.

Three cases of visuospatial stimulus-bound automatic writing behavior were identified among 80 patients (4%) with acute right cerebral hemispheric stroke. All cases had similar clinical characteristics and writing behavior, and visuospatial stimulus-bound automatic writing was related to visually perceived letters. This syndrome might be specific for right hemispheric stroke and might be included among other hypergraphic syndromes attributable to right hemispheric damage.
