Synesthesia is, as visual migraine aura, a common and fascinating perceptual phenomenon. Here we present a unique case with synesthesias exclusively during visual migraine auras.
A 40-year-old woman with a cyclic mood disorder had suffered from migraine with visual aura for several years. On several occasions she had experienced "mixing of senses" during the aura phase. Staring at strong bright light she could experience intense taste of lemon with flow from the salivary glands.
Acquired synesthesia, exclusively coincident with migraine aura, gives support to the idea of an anomalous cortical processing underlying the phenomenon.
联觉是一种常见且引人入胜的知觉现象,就像视觉性偏头痛先兆一样。在这里,我们呈现了一个独特的案例,其联觉仅在视觉性偏头痛先兆期间出现。
一名 40 岁女性,患有周期性情绪障碍,偏头痛伴先兆已数年。在几次先兆期中,她都经历过“感官混合”。当她凝视强烈的亮光时,会感觉到强烈的柠檬味,并伴有唾液分泌。
获得性联觉,仅与偏头痛先兆同时出现,为该现象背后存在异常皮质处理的观点提供了支持。
