Writer Alex Witchel watched her mother disappear in plain sight. Her mother, a smart, loving, ultra-capable woman, was only 70 when her dementia began. Witchel was raised to fix what is broken, but in this case, fixing wasn't possible. What was possible was holding on to her mother through love, through humor and through cooking her mother's dishes. She tells the story in her book All Gone: A Memoir of My Mother's Dementia. With Refreshments.
