Herself has informed me that I should post an update.
The title above for those of you who have learned some of the Geordie vernacular will indicate that there is no improvement in her condition. She remains largely bed-ridden as her brain still can't tell where the floor or the ceiling are or locate herself in the space in between. That's why she has not been at the computer as moving/flickering images make this sensation much worse for her.
There seems to be nothing for it except wait and see with this one. she does appreciate all your messages which I have read out to her, and for the e-mails. Please don't be worried that she has not replied to e-mails, she simply can't face a screen at the moment.
I'll let you know as and when there is improvement.
