I am sorry to hear of your issues with Dementia. There are 5 children in my family, we're all past 60, I'm 77. Four have Dementia, my youngest sister thinks she may have it, just not diagnosed. I have no symptoms, but I'm Stage 4 Kidney disease. When my oldest sister, to whom I was closest to, announced her dementia, I was definitely guilty of hide and go seek. Deny & she'll be better was the way I hid the disease at first.
As it progressed, the symptoms came out very loud & clear. She didn't know me. Now those of us in town have breakfast together once a month with time racing against us. I am using what I learned with my now deceased older sister to support my brother when we're together. I pray for cures for healing this terrible disease.
