Hello my mum has been recently diagnosed with AD otherwise she is a very healthy 73 year old. Both her and dad live independently but recently it has become more of a daily struggle. No two days are the same and things can change in a heartbeat. We are at currently trying to see which medication suits her best, she lasted a week on Donepezil before experiencing hallucinations. We now have her on memantine but are struggling to get a hold on them. We had to change from night time administration to lunchtime, this seemed to suit her great for the first week of 5mg dose but as we go up the doses she is experiencing severe agitation at night before sleep. I work full time and spend every afternoon and evening with them to help where I can. It is becoming a struggle for Dad though, patience is running out. I would love to know if anyone has any experience of this medication, and the struggle to get it right. This is so new to us and sometimes you feel as though it's just happening to you. Finding this forum has been like a light being switched on as reading through the posts has helped reassure me.
