Visual hallucinations and palinopsia in strokeCitation
Læknablaðið 2001, 87(4):299-302Útdráttur
We describe three patients who experienced simple and complex visual hallucinations, palinopsia and palinacusis in the immediate post-stroke period following parietal and occipital stroke. The hallucinations and palinopsia occurred in a defective or a blind visual field in two of the three patients. Such hallucinations are relatively uncommon but should be recognised as a complication of stroke, as part of or following an epileptic attack and after brain surgery. They usually disappear with time.Þessi greinarstúfur lýsir ofsjónum og ofheyrnum sem komu í kjölfar heilablóðfalls hjá þremur einstaklingum. Ofskynjanirnar voru mismunandi, allt frá einfaldri litasýn til endurofsjónar (palinopsia), endurofheyrnar (palinacusis) og fullmótaðra ofsjóna, sem ýmist urðu til í helftarsjónsviði eða í öllu sjónsviðinu. Heilaskemmdir voru staðsettar á hvirfil- og hnakkablaðs- (lobus occipitalis) svæðum. Niðurstöður: Ofskynjanir, bæði ofsjónir og ofheyrnir geta komið í kjölfar heilablóðfalls og hverfa yfirleitt af sjálfu sér dögum eða vikum eftir heilablóðfallið. Æskilegt er að læknar þekki til þeirra, geti útskýrt einkennin fyrir skjólstæðingum sínum og upplýst þá um horfur
