Meet Lydia and Darlene. They are two sisters who had their mother, older brother, and three aunts all die with advanced Alzheimer’s disease.

Lydia, the older sister, also had advanced Alzheimer’s and almost never recognized her baby sister, Darlene.

One evening about a month before dying, Lydia had a moment of clarity. For a brief period of time, she was aware of her situation and recognized Darlene.

Lydia said, “Sis, I’m so glad you don’t have to worry about getting Alzheimer’s.”

Darlene replied, “I don’t know what you mean. I’m 12 years younger than you and I don’t see how you think I won’t get it, too.”

Lydia looked her sister straight in the eyes and said with a slight smirk on her face, “I know, because you have to be smart with a high IQ in order to get Alzheimer’s. So I know you’re safe!”

Key Point: A spark of humor can come when least expected. I try to cherish each of these moments.
