Abstract
Caloric stimulation induced a transient reversal of multimodal hemispatial cognitive deficits in an 81–year–old woman with an acute left cerebral hemisphere stroke. The patient had unawareness of her right hand (asomatognosia), right–sided visual unawareness (hemineglect), aphasia and right–sided weakness (hemiplegia) prior to the stimulation. Transient improvements in impaired sensory, motor, linguistic and cognitive function developed within 30 s following application of the caloric stimulus and onset of horizontal nystagmus. The effect persisted for 3 min and ceased completely after 5 min. While several recent reports have described the capacity of caloric stimulation to transiently improve or reverse a wide range of attentional, cognitive and motor impairments, most examples are in right–hemisphere–damaged patients with long–standing brain injury. Typically, patients have been tested several months or years after the onset of the deficit. A possible mechanism for the temporary reintegration of multiple cognitive functions in this patient is discussed.
