Alzheimer's disease and technology aids?

Hello all,

My mom has what appears to be early onset Alzheimer's (she will be evaluated by a neuro specialized in the disease later this month). In any case, this disease has got me questioning how technology might play a role in this field going forward.

Does anyone have any applications that they use to help care for loved ones or any devices? I've seen medical alert bracelets/pendents, medication reminders, etc. Any other recommendations or thoughts?

I know my mom has issues remembering when she has to take her medication, appointments, some names, etc. She remembers how to use her iPhone. I know how to develop some programs and was interested in getting some general feedback as to what would be best to include in an application to help make life easier for my mom (and others)?
