Alzheimer's hits different people at different ages and in different ways. Trump's mental issues have existed for a very long time and have been exacerbated by many issues (inherited money, lack of parental supervision or care, bullying success). At this juncture it is hard to say how much of his personality is fixed, and how much might be the result of early-to-mid onset Alzheimer's, as many elements are similar (paranoia, fantastic thought processes, inattention, poor fact management). Since his father had dementia, there is every reason to expect he will manifest it as he ages. Although Fred Trump was only diagnosed at age 87, given his financial status, he was probably suffering earlier in his life, but its effects were masked by the life of privilege he led. The same is probably true of his son.

A well reasoned argument is like a diamond: impervious to corruption and crystal clear - and infinitely rarer.

Here, as elsewhere, people are outraged at what feels like a rigged game -- an economy that won't respond, a democracy that won't listen, and a financial sector that holds all the cards. - Robert Reich
