Explanation of VS study in Germany

Many of our donors have asked for a little more explanation of what the German visual snow study was looking for, which we helped to fund in 2014. I recently wrote to Dr. Schankin and this was his reply:

With that study, we investigated the processing of basic visual information in the brain of patients with visual snow. The aim was to see if we can find objective electrophysiologic data for the condition that might serve as measures for future treatment studies. This is important since - in contrast to radioactive brain imaging that we did before – these tests can be repeated.


The results of this study need to be reviewed during the meeting and by colleagues before any clinical application can be designed. 

It is Dr. Schankin's hope that colleagues will be able to look at the data this coming September. 

While every part of Visual Snow research is crucial to better understand this condition, we are still in the very early phases of research. More financial support is needed in order to continue through the necessary phases of medical research. Please consider supporting us today. We still need almost $50,000 more to ensure that Dr. Puledda's salary is covered for another year. Without this money the research will have no funding to continue. 

VS testing to begin in London in May 2017

I'm sorry that there was such a long delay in hearing from me, but I sustained an eye injury in Feb and am only recently returning to limited computer use. 

I do have an update from London to share with you. Patients have begun to be qualified and scheduled for testing. Scans are scheduled for May and June at King's College. This is an important phase of research, because what is learned from these scans will determine how we enter into a treatment phase of research. Without this phase of research, we will not be able to proceed to medication testing. With that being said, I've been approached about funding for Dr. Puledda's salary for another year. Dr. Puledda works under Prof. Goadsby and is the primary doctor assigned to the Visual Snow research at King's college. As stated in previous updates we need approximately $70,000 USD per year to employ her. Currently we have only raised $20,000 USD which is a far off sum from what is actually needed to secure her. 

Almost all of you reading this who have VS have likely undergone an MRI. You have likely seen the very high bill to your insurance, or you have paid out of pocket. It's not uncommon to see bills over $1000. We are very fortunate that King's College covers all of these costs towards VS research. We need to assist them though by being able to pay Dr. Puledda for her time and efforts on our behalf.

Research to begin in London

Patients have begun to be recruited for the imaging study in London, England. Within the next two months we hope to see the first patients being scanned for the MRI study.   Continued funding is asked for as we are just in the beginning phases or research and want very much to see it continue. It costs almost $80,000 USD per year to employ one research doctor. We would love for you to become a monthly donor and help us achieve our research funding goals.

Visual Snow Questionnaire responses returned

A communication to all Visual Snow sufferers participating in the London Questionnaire Study on Visual Snow


Thank you for your extraordinary interest in the London Questionnaire Study on Visual Snow! So far, we have been in contact with over 450 subjects, who expressed interest in participating in our research on this disabling condition.

We have emailed the documents for the study including two questionnaires to a large number of you. To date, however, only 67 have returned both documents. This is neither a representative sample of the 450 subjects nor is it sufficient to understand the condition Visual Snow in detail.

Direct participation from the Visual Snow community is extremely important for our goal to advance research and with it treatment of this problem. With this update, we would therefore like to invite all subjects to help us by returning their questionnaires as soon as possible. We believe that this study will gain significant important information on Visual Snow, but only if we are able to reach a substantial and meaningful number of participants.

Thank you again for your help and collaboration!

Professor Peter J Goadsby
