These have been mentioned a few times. I thought I would add the link again as enrolment is still open for one course and the opportunity is there to express interest for another - https://mooc.utas.edu.au/courses I think a few members have done the courses and have found them useful. I've did the Understaning Dementia one in 2014. I've just signed up for the Preventing Dementia one. I'm not so sure about the idea of 'preventing' dementia but the first course was so good that I thought it worth taking a look at this. The courses are online and free.
