Today Barbara welcomes Dotti McLean. Dotti’s husband, Brian, was an international expert in environmental policy who loved to build furniture, paint, and play the boogie woogie on the piano. After retiring 10 years ago, Dotti says, “things started to change.” She tells Barbara about the early signs, when Brian was having trouble following conversations, losing his train of thought, and forgetting basic things. They discuss the progression of his cognitive decline, and how Dotti struggled to keep up, learning the hard way that Brian didn’t react well to many prescribed medications and supplements.
