Hi OP, I am in a similar boat to your DH, 47 though, similar score and showed mild atrophy in my CT scan 'out of proportion for her age' They have now done a PET scan, which we got privately because the wait times with the NHS would have been longer and could have it in a matter of weeks.
I'm scared, they also say it could be due to e.g. depression / meds or chronic pain impacting on things (I had shingles on my head and on pain meds for that) so it is inconclusive.
I've been waiting about a month for the memory clinic doctors to discuss it at their neuroradiological (as they called it) meeting to see what the results are..
So far the have put, diagnosis: memory symptoms- under investigation. Is your DG anxious, as they said anxiety could impact on the score results.
I have a family history of dementia and copy of the APOE4 gene. So it is all a bit worrying.
Despite this, family just say 'you're fine' so I am kind of dealing with it all alone. I don't work, anyway, get PIP for my other health problems, so for now it is sort of another thing to add to it all. My best wishes to your DH, maybe they will do some more scans to help advise
MY PET scan was, I think OK "did not show convincing evidence of a neurodegenerative disease' however showed mild changes in the 'sulcal depth' - I have just got this from the radiology dept and have not discussed it with anyone yet. The waiting game is hard, I am hoping they might contact me this week about it, as it was meant to be before the end of September.
Our memory clinic is a national centre of research, it is highly rated but they are overwhelmed, I think as it says around a year for a first appt on their website. They saw me a bit quicker, maybe as younger.
I am kind of coping OK, was putting the problems down to the menopause but am on HRT and they have remained. Trying not to google too much and focus on things I can do tom try and help, such as have started a med for blood pressure, losing weight, etc trying to exercise.
