My wife of 56 years was diagnosed with MCI 18 months ago. Since then I have noticed a diminished interest in routine activities around our home. For example, she loved gardening and while she seems to notice things need to be done she rarely acts on them now. The new behaviors are sitting in a comfortable chair, reading and playing solitaire. She seems detached from the world she used to love. Is this new pattern part of the disease? We have a new neurological testing battery lined up next month. Thanks.
