Other disturbances of higher cortical functionsAchromatopsia (loss of colour vision)"I thought I did not get aura with my migraines; no seeing stars or sparkly, flashy patterns. But I do - sometimes - get tunnel vision and after that the world seems glossy, stylized, black&white (sometimes) or it gets either very sharp or very fuzzy. I though it was just some strange thing my eyes/brain was doing, but could this be the aura I have heard so much about?" (Anna Decker, Newsgroups: alt.support.headaches.migraine, Subject: Aura?????, May 17, 2000) A further cases of achromatopsia occurring as migraine aura symptom has been reported by Lawden and Cleland (1993). Balint's syndromeShah and Nafee (1999) described "a patient with recurrent episodes of migraine in whom headache was preceded by a constellation of visual symptomatology which constituted salient components of Balint's syndrome. This syndrome, consisting of a triad of simultagnosia, optic ataxia, and oculomotor apraxia, is seen with bilateral lesions of occipitoparietal cortices affecting connections between visual cortical regions and the frontal eye field." (http://jnnp.bmjjournals.com/cgi/content/full/67/4/554, August 8, 2004) Chromatopsia (distortion of colour vision)"Aura can vary soooo much from person to person... Sometimes my surrounding take on an odd orange/yellow color before a migraine strikes." (Mary, Newsgroups: alt.support.headaches.migraine, Subject: Aura's and Warning Signals????, December 3, 1997) Prosopagnosia (agnosia for faces)"Yep I get them - yuk: Lots of visual disturbances with coloured zig-zags that flash with tunnel vision. For me, the first sign of an impending migraine is an inability to recognise faces. At that point I go straight to bed with neurofen (iboprofen) or aspirin in a darken room and can usually sleep through the entire event (about 8 hours). If I don't do this, I get a splitting headache behind the eyes much as you describe. I get nauseous and sometimes vomit. My speech centres get damaged and I can't seem to put words together properly - for example one time I wanted to say 'Jamie and Carey' who are two friends of mine but all I could put together was 'Shamie and Arey' or variants of that - sounds weird but I just don't seem to have proper control over whatever language centres are involved. I also get paraesthesia and other neurological stuff." (Paul Jones, Newsgroups: alt.support.mult-sclerosis, Subject: Migraines, August 18, 2000) Further cases of prosopagnosia occurring as migraine aura symptom have been reported by Lawden and Cleland (1993) and Martins and Cunha e Sa (1999).
Right-sided hemianopia and prosopagnosia of one's own face"The pattern changed on Friday. I had two 'normal' migraines in quick succession on Friday morning, and then on Saturday morning I was checking my hair in my mirror and I couldn't quite see myself - I had trouble perceiving the right hand side of my face, and it felt as if I was looking at someone I didn't recognise. That sensation is still there (Sunday afternoon) and I have slight numbness in my hands and neck. I can see detail perfectly well, but I can't seem to take in the overall picture of what I'm looking at. As this is so out of type, and I have a history of stroke in the family, I've started to get worried. Before I go running off in a flat spin to my doctor, does this sort of thing ring a bell with anyone here?"
