Persistent migraine aura symptoms (e.g. visual snow)

I hope that we can all join together and beat this...

"Hi All,

Well, it is really upsetting reading all this, I'm in fact in tears, but am also happy to have found people who have similar problems. First I would like to say I hope that we can all join together and beat this, because there is no way I'm putting up with this shit for much longer...

Here is my problem:

I started getting migraines in November 2004, I didn't know what it was because it was just the visual disturbance - just zig-zags and a few other bits. Then, three more with headache (a-ha migraine) and visual disturbance quite bad. My third one was quite crazy and I had problems with my vision for a whole week - seeing something and then seeing it again. My fourth migraine February 2005 had really mad aura - skipping lights, things seeming to melt, zig-zags and finally kaleidoscopes spinning and skipping in fours. So scary! Then nausea, then Sumatriptan, then fucked up vision that has not really gone away.

Vision proplem: I look at something, turn my head and then see it again. Or I am looking at something, move it and still see it where I moved it from (the longest an image has remained in my sight is 8 seconds). I am having biggest problems watching tele and driving. Am hyper aware of reflections and shadows, problems looking at the sky - sort of turns into stars, also looking at white walls. (Sunglasses do help on computer.) Feel overall confused, disoriented, less coordinated, and really upset about this as am active person with pretty good health until now. (Had some tingling in back of head.) (Had MRI and results were normal.) Did sort of think stroke at one point.

So, I hope that a doctor will read this and have the proper diagnosis and solution, and if not I hope that all the people that are having this problem can get together and come up with something. I would love to hear more. Thanks everbody for discussing this.

Best, Sofia"

Visual Snow Study at Glasgow Caledonian University in Scotland - Call for Participants

The study by Dr Gael Gordon (ggo2@gcal.ac.uk), Dr Velitchko Manhilov and Prof Gordon Dutton from the department of Vision Sciences at Glasgow Caledonian University in Scotland (see here) promises interesting results in term of objectifying the disturbances of visual snow sufferers. We have agreed to cooperate in this project and have offered (provided the subject's informed content) to contribute the clinical data and the diagnoses obtained in the internet survey project. So if you participate in the neuropsychological examination at the Glasgow Caledonian University University in Scotland, please tell the researchers that you have participated in the internet survey (and tell them your internet pseudonym), and send the same information to kpodoll@ukaachen.de, so that we can put together the data.

The tasks are computer based and involve judgements regarding stationary or moving shapes presented briefly on a computer monitor. The tests take around an hour although two appointments may be necessary to complete the tasks in some instances. A small fee is payable for participation.

The study has the potential (1) to objectivize the visual complaints of vs sufferers, similar studies have also been done in HPPD as early as the 1970s and there is an urgent need for similar data in vs; (2) the data can act as a validation of the survey data and the taxononmy (diagnostic classification) achieved in the internet survey; (3) it will prepare the grounds for further studies aiming to analyse the potential mechanisms of the disturbances in vs.

Click to Peer Out At My Within

"Click to peer out at my within. With closed eyes, I may see 'The Sandbox' - this is a small patch of vision that resembles a field of sand particles drifting past my vision. They're almost always moving, and they can drift in any direction either on their own, or I can 'steer' them. Again there are green, red, yellow and blue 'sparklies' - these look like confetti - just a few bits of luminous confetti trickling towards me from some point in the distance. The colors of the sparklies come in pairs - they'll either come in red/blue pairs, or yellow/green pairs. Meaning if I see a yellow sparkly, a green one is usually also nearby and/or soon to follow, and if I see a red one, a blue one is also nearby and/or soon to follow, and vice versa."
