My mum is 62. We don't live near each other but we'd talk daily. Lately I've noticed her repeating info/little stories to me on the phone, just little things, things you could write off as thinking she'd told someone else but not me. Today though she told me that last evening, she cooked two evening meals, unintentionally. She laughed it off, but I know she would be worried as her own mum died with Alzheimer's. What if anything should I do? I'm scared to talk to
