Minor memory loss and difficulty learning are common for first-stage Alzheimer’s disease. You may also notice a loss of energy and spontaneity, as well as mood swings, confusion, trouble communicating, and difficulty organizing. It is also not uncommon for those with mild Alzheimer’s to be withdrawn, shy away from new people and new places, and to prefer activities and people most familiar to them. With these new emerging realities, they could exhibit anger and frustration as well.
