Due to the emphasis shifting to the earlier diagnosis of dementia, more people are assessed who report memory problems.

[24] [25] Globally, approximately 16% of the population over the age of 70 experiences some type of MCI. [medical citation ...
As we get older, we get wiser, but, health-wise, we also get more complex. Over the years, life accentuates our differences. Look at 100 20-year-olds and most are similar in health. But 100 70 ...
New research published in Neurology found that cognitively healthy people who self-reported memory problems had early signs of Alzheimer’s disease, such as higher tau tangles, in their brains.
The difference in memory between normal aging and a memory disorder is the amount of beta-amyloid deposits, hippocampal neurofibrillary tangles, or amyloid plaques in the cortex. If there is an increased amount, memory connections become blocked, memory functions decrease much more than what is normal for that age and a memory disorder is ...
As with memory itself, a key principle for technology is that “less is more.” All the life-logging in the world will not enable us to remember all our experiences, nor is that a desirable goal ...
Semantic dementia generally affects semantic memory, which refers to long-term memory that deals with common knowledge and facts. SD was first described by Arnold Pick in 1904 and in modern times was characterized by Professor Elizabeth Warrington in 1975, [ 8 ] but it was not given the name semantic dementia until 1989. [ 9 ]
