Hi my name is Sue and would just like to find out more for my mum who I'm starting to get worried about. Mainly memory issues, most expected for someone of 71 years young but for the past 6 months there's been minor confusion such as asking when we're away when we're not, and repeating phone calls within half an hour which concerns me the most. How do we tell the difference between normal older age memory problems or something more serious? Many thanks for any help. She's recognising that her brother has early warning signs but not herself. thanks again.
