For IAAD last year, Ataxia UK set up a webpage specifically for this. There were ideas for awareness raising, including online awareness raising. 3 short videos were made which can be found by going to this link:
By clicking on each of the videos you can share them to either Facebook or twitter by clicking 'Share' in the top right hand corner and then clicking on which type of social media you would like to share it to. I apologise if you already know this process of sharing but I didn't until 10 minutes ago!!. I have managed to put them on my facebook timeline so if I can, anyone can!!
There is a new video being launched this 25th September to coincide with the launch of Ataxia UK"s fabulous new fundraising campaign-20:20 Vision : Aiming for a cure. I will of course post the link for this when it is available. However these three videos from 2011 explain ataxia and Ataxia UK wonderfully as well and can easily be shared to your social media for as much awareness raising as possible!
