Alzheimer's is a disease that affects the brain, not a congenital brain state. It's a completely different category. Not everything that affects the brain is a divergence.Woodchopper wrote: ↑Fri Feb 02, 2024 4:33 pmFirstly, it’s an interesting and as far as I know unresolved question as to whether someone was or was not born with some conditions. For example, the symptoms of bi polar disorder might not be obvious until someone is an adult, but arguably their neurology might always have been atypical. The same could be said for many other conditions.Tessa K wrote: ↑Fri Feb 02, 2024 3:20 pmThey're not all conditions people are born with in your list. Alzheimer's definitely isn't.
Some people may be prone to depression or anxiety all their lives because of the way their brains work while others may experience them occasionally as a response to external factors. PTSD causes non-typical brain responses, how does that fit in?.
Some behaviours such as addiction or eating disorders can be treated - and in many cases cured - others can't. At best they can be managed, eg ADHD or schizophrenia.
So can some people have a kind of transient ND? I don't think so.
But more importantly, I don’t see why it should matter. It seems to me to be ridiculous to to, for example, describe someone with agnosia as ‘neurotypical’. Their brain has been altered by a stroke and they can no longer recognise everyday objects. The same applies to Alzheimer’s, certainly someone may not have have had symptoms until old age, but it would also seem very odd to describe someone with Alzheimer’s as being neurotypical. Their brain is being altered from within with the result that, for example, they can’t form new memories.
Yes, some people's traits become more obvious around puberty but that's because of the brain interaction with hormones and other biochemistry bringing out what was already there.
