palinopsia
Pronunciation: pal-in-OP-see-ah
Visual perceptual disorder characterized by persistence or recurrence of visual images after the stimulus has been removed.
Full Definition
Palinopsia is a rare visual phenomenon in which patients continue to see visual images after the original stimulus is no longer present. This condition manifests as either immediate persistence of images (like visual trails following moving objects) or delayed recurrence of previously seen images. Palinopsia can result from various neurological conditions including migraine, temporal lobe epilepsy, posterior cortical lesions, or medication effects. The disorder reflects dysfunction in visual processing areas, particularly the occipitotemporal cortex, and can significantly impact daily activities such as reading and driving.
Usage
Usage note: Often associated with posterior cortical lesions or medication effects.
