Abstract:
Palinopsia is an illusory visual phenomenon consisting in the persistence or recurrence of visual images after the exciting stimulus object has been removed. It has been reported in association with parietal and occipital lobe lesions, migraine auras, and related to the use of several drugs and illicit drugs. Here, we report the case of a 23-year-old woman with a 4-year history of episodic migraine with aura who developed palinopsia during sequential prophylactic therapies with topiramate and zonisamide. Although the exact physiopathology of this phenomenon remains unknown, topiramate- and zonisamide-induced palinopsia support an increase on serotonergic activity as a possible mechanism for this visual disorder.
