So, My Mum has RA, she is in her late 60s and diagnosed with RA in her late teens. She has been on weekly injections 20- 25mg of Methotrexate for past 2-3 years. He memory is shot to bits. I keep reading various studies how Meth can cause brain fog and issues with cognition. I really just want some clear answers!! Her memory seems bad all the time, not just a couple of days after the injection but she has been on it for quite a long time. She has been to GP who carried out some memory tests and told her to come back in 6 months time. I love the NHS (I work for it) but I do worry that they will just slap her with a dementia diagnosis due to her age and leave her on the meth. without investigating if it is the meth first. We have mentioned her memory to the RA consultant who just went 'mmm' and wrote it down. She is back there end of the moth and me and my sister are pushing for a CT head scan to try and get to the bottom of it. Has anyone here got any advice/ experience of similar memory issues? If so did you/your relative/friend come off the meth and see an improvement in memory??
