Worried about my 90 year old dear Mum who has a worsening short term memory. She has been taking Levothyroxine for decades and her results from last September were free T4 20 (12-22) and TSH 1.04 (0.3-4.2). They won't test T3. I have taken her to the doctor on numerous ocassions and she just has memory loss on her notes. They won't do any other tests but Mum won't go again as they make her feel its a waste of time. Mum has believed in vitamins and minerals and has been taking them for the last 30-40 years. She is quite fit for her age and still living on her own at home. She is taking numerous supplements and her B12 level is 723 (197-866) and serum folate 20 (4.6-18.7). Mum is taking one tablet for high blood pressure only. Her liver has improved greatly since coming off statins, cholesterol in the normal range. But she has weak kidneys. I am wondering if a trip to Dr P could improve her thyroid or am I being an overly worried daughter? I want to do all I can as I believe the elderly are just left when it could be something easily rectified. I give Mum 1000mg methylcobalamine sublingual a day plus other separate supplements. I am now doing raw veg and fruit smoothies as she is not eating properly. If Mum gets too bad then she will have to live with me and to be honest, although I love her dearly I do get stressed when I visit and it doesn't help my weak adrenals or thyroid problems, I already look after two children after my husband left me and I had a heart attack. I don't think I could take anymore stress. Any ideas would be appreciated as my brain fog makes it all too much to contemplate or to think clearly.
