Hi. My husband has been having memory problems for a couple of years now, but they seem to be worsening. He has also started jerking and twitching during the night or if he naps during the day. It is getting much more severe, and it really disrupts our night. Is this jerking/twitching due to AD? My husband has no formal diagnosis as yet, but we are going to the specialist memory clinic next week for a four hour test. My doctor advised me to contact the AS, as she thinks he has dementia. Any advice will be truly welcome. Thank you.
