Hello
@Murphy2 and welcome to the Dementia Support Forum. I am sorry to read about your mum's LBD diagnosis. My husband also has LBD and is on the patches. He has been on them for almost five years now. He still has hallucinations and nightmares but it is hard to tell if they would have been worse without the patches.
I do hope that you will find the forum useful and will continue to post if you have any questions or even if you just want to share how you are feeling at any time. Our members are very helpful and supportive.
