Bizzey, I'm sorry things are so hard at the moment.
Not sure if it will help, but I have been through all sorts of tests due to demential-like symptoms. Started with odd episodes that were initially suspected TIAs, but found not to be, then word finding problems, clumsiness, short-term memory issues etc. They are still not sure what it is, but it's not dementia. I have lots of lesions, which are causing the symptoms, but I'm doing fine almost two years since it all started. I go through periods of not being great, but am at my best when I keep myself as healthy as possible with diet, nutrition etc. There can be lots of reasons for dementia-like symptoms apparently, some of them very easy to treat. CTs are cheaper than MRIs so it's good that they didn't feel the need to jump straight in with a full MRI.
I'm another one who really misses her Dad, but doesn't miss his illness. It's so hard when you feel powerless to help. I will keep everything crossed for you and am sending big hugs as well. ((hugs))
Aunt, we've been through the dietician loop with ds1 as well and they were equally useless. Tried to tell me to give ds porridge, when it's in his notes that he is to be treated as coeliac.
Saw her a few times, she said his diet was excellent, offered no advice and then discharged as she said there wasn't anything more she could do.
He is rake thin, not a scrap of fat on him anywhere and he hovers either just above or below the 2nd centile for weight depending on what's been going on for him. Paed doesn't seem to think this is an issue, despite the fact he was always between the 9th and 25th centiles when he was younger and only started to get this thin following illness when he was 4.
He eats enormous meals, bigger than dh and he's a big eater and it doesn't matter what we do, he never gains any weight.
As for Indigo, I know what you mean but she means well and is passionate about her beliefs. She can come across a bit militant and er ... direct (for want of a better word) sometimes, but she doesn't mean to upset anyone.
