I started some public speaking on caregiving because I feel there are a lot of people who don't have access to computers. I am starting with "How to Have Heart to Heart Talks" with loved ones to reduce or eliminate the #1 cause of hurt - unmet expectations.
I had nothing to gage old age on as I was rarely around my late grandparents as they lived way out-of-state. I always thought my parents would be mobile and active at 90 as they were at 70 and 80. Boy was I blindsided.
It grieves me to see how many people think their loved one is manipulative or attention-seeking or lying when in fact the behavior is related to a malfunction in the brain!
It is not surprising but it is unproductive when people (including some medical professionals) think all dementia is the same, and all of it is like Alzheimer's.
You certainly can't cover all there is to know about dementia in one short talk, but you could convey the basics and also come armed with information about other resources, including local caregiver support groups.
Or for those who do take in their parent(s) to Care for them 24/7 then find out it is too exhausting and therefore time for a professional facility.
The talk on Medicaid could be both national and are specific. What are the requirements in the area? What is spend-down? How does it all work if someone is in a nursing home? What is Medicaid recovery? Under what conditions do caregivers have a right to keep a house in an area? These questions come up often here.
