The process of reporting possible signs of dementia within agreed ways of workings usually works like this - a physician would receive a patient and view his symptoms - he would check for his memory capabilities and his decision-making style. If he would see that the patient exhibits certain memory deficits, this would probably warrant further investigation whichcould lead to a dementia diagnosis.
Coupon Book: A coupon book is a book full of "coupons" homemade by you. You make "coupons" personally made for them, that they may like. Examples, "I will do your laundry for a weekr", "let you borrow any clothes for my closet", or "Choose what you want for breakfast and I will make it". I would make this for one of my siblings. Hope This Helps!
