There are some silly people (in the US more than here) who like to claim that President Trump is suffering from ‘dementia’. Many people have very mixed feelings about Trump – liking some things he does and disliking others. Well, that’s okay – he’s a politician! But, as you know, some people suffer from TDS – Trump Derangement Syndrome. These are the people who seem to believe everything Trump does is evil. Things that, if done by someone else they would approve of, they find disgusting just because it’s Trump who does them. And it is a sign of TDS when someone claims that Trump is ‘clearly displaying signs of dementia’. The word ‘dementia’ was first used in English as a medical term around 1598. Behind it is the Latin word demens meaning ‘madness, craziness, folly’. But these days ‘dementia’ has a very specific medical definition: ‘a usually progressive condition (such as Alzheimer’s disease) marked by the development of multiple cognitive deficits (such as memory impairment, aphasia, and the inability to plan and initiate complex behaviour)’ (Oxford English Dictionary). And whatever you think of Trump’s words or his behaviour he is clearly not suffering from that range of symptoms! As you know Australian traffic authorities often apply ‘double demerit’ points on holiday long weekends. My wife insists on calling these ‘double dementia points’! Which I rather like. There are definitely some drivers, and some traffic conditions that could drive you mad!
