I’m a part-time caregiver for an 86 year old woman. She keeps burning pots and pans when I’m not there. I thought she was “forgetting” that she was cooking until the day I saw the pot on the stove, the flame very high, but nothing in the pot. They get so badly burnt they have to be tossed out. It’s happening more frequently. Is this a sign of Alzheimer’s? She is having memory issues as well.
