M is a 72 year old male who has early Alzheimer’s disease. He lives in his own home with an elderly spouse. He likes to go out into the community unaccompanied. Some of his impairments are mild memory problems, spatial disorientation, difficulty in finding the right words, taking some time to recognize that he is lost when he becomes lost, embarrassment in approaching others and asking for directions, and inability to generate solutions. These impairments are episodic (occur only occasionally).
Aim/Goals-
To be able to manage everyday life activities without being overseen
Frustration and pain point-
Difficulty in remembering recent events such as conversations, current tasks and family news

Help provided should include standard components: what the current task is? What actions are required to accomplish it? Where he needs to go to accomplish the task?
Must be unobtrusive and unlikely to attract the attention of others
