As someone who's had visual snow for over 20 years and never linked it with other symptoms that are described in the study, my mind is blown. I've skimmed halfway thru the study and have tears in my eyes reading this, because for years I've not been able to figure out why I've felt so weird...and mostly just try not to think about it (but I'm always worried about it in the back of my mind). So random too, just... Source: over 1 year ago

Up until recently SE had a free (old) version available on the site; you should still be able to find a mirror of it somewhere but I don't know of one personally. Otherwise, SE is available...

Numbers as overwhelming as these are meaningless to our little minds. Then, do yourself a favor.
