I hadn't heard of the insulin project. Sounds like a brilliant concept to me.
Sunny, I can so totally relate to the examples you have given, particularly regarding cognitive testing and concerns about dementia. It has made me think about something else for which I need to ask advice, but that's for another thread. You have such a great way of expressing yourself; I've lost the ability to think as the brain fog and fatigue have got the better of me and I miss those days when I could be clear headed, wake refreshed, cycle to work, and stand up in front of a lecture room of students and engage on a level that now completely eludes me. (Just put that in there for perspective rather than a whinge)
One of my stories from the hospital involved an overnight stay earlier on this year.
First thing in the morning, the doctor walked in to my darkened side room:
Doctor: "It's very dark in here!" turning on all the lights and shining the bedside light on my face. I cover my eyes.
Me: "I have a migraine "
Doctor: "oh. Your right eye lid looks very swollen and puffy. It's not normal to look like that"
Me: "sorry, I'm a bit away with the fairies at the moment as they haven't brought round the meds yet, and I'm having a little difficulty concentrating with the migraine as well and the lights aren't helping " He doesn't take the hint and the lights remain on.
Doctor: (repeats stuff about my eye)
Me: "I'm in the middle of a cluster headache season. Of course it's puffy and swollen."
Doctor: "well it's not normal and I'm very concerned about it. But I'm more concerned by your admission that you have memory problems " and promptly started trying to do a mini mental state exam on me!
It all ended in complete disaster with me fiercely arguing with the doctor and telling him he was a complete idiot who should be struck off for incompetence.

Serves him right for not listening to me! He didn't have the courtesy to introduce himself when he walked into the room either, which I class as total arrogance. Plus there were errors on my discharge summary diagnosis that I demanded be changed before I left the ward. I really didn't want his mistakes indelibly placed on my medical records, so I staged a sit in at the nurses station until it was sorted by a lovely but frazzled junior doctor.
