Abstract

The literature on palinopsia (visual perseveration) is reviewed, utilizing case reports of 46 patients who demonstrated this symptom. The most common etiologies for this symptom are space-occupying lesions, cerebral infarct, and seizure activity. The vast majority are due to central nervous system pathology occurring in the posterior (occipital or parieto-occipital) region, often in the right hemisphere. Proposed mechanisms for palinopsia are also discussed.
