Yes this is it (the Alzheimer)! Someone wrote some detailed notes about it, but I can't really remember who..

FYI, I think that two of the links in today's post are also close to your subject area (The post is scheduled in not quite 3 hours).

I usually read them all, but sometimes quite a bit delayed ... This strongly depends on the amount of work I have. I will try to have a look today, but I will most probably check tomorrow ;)
