Thank you for posting the link here, Howmanytimes.
Like I said in your thread, I don't think most of our MLC are having early dementia. I agree some signs/symptoms can be similar, but, as a general rule, MLCers come out of MLC. Once their crisis is over, their behaviour goes back to normal. That does not happen with dementia.
Not saying that some MLCers may not be having early dementia (or not so early, since a few are on their 60's), but the way I see it, they are separated issues.
Could those who have MLC be more vulnerable to, later, have dementia? I really do not know.
