For anybody who has any interest in dementia, through family, friends, work or just to get a handle on one's own risk factors, there is an excellent free course available now through the University of Tasmania The Wicking Dementia Centre It's received a rating of 4.9 out of 5 based on 5,000 ratings in ClassCentral. I finished the related Preventing Dementia course when it was available last year, and learnt a lot. I'm currently working through this course, and recommend it. I found it particularly interesting to learn about some of the modifiable risk factors of dementia, things which can be done earlier in life in many cases. Some of these risk factors weren't so obvious.
