Alzheimer's and genetics

When my brother’s password reset hinged on the name of his first pet, we discovered how fragile ordinary memories can be. The milestones remain, but the small details—the cat’s name, the everyday moments—are the first to disappear. When dementia erases the past, someone else has to hold it.

A nurse reflects on the moment she realized sharing family news with siblings who have Alzheimer’s no longer helps—and how dementia quietly changes family communication.

In 1990, my father was diagnosed with Alzheimer’s. We lived together for years, yet we never talked about what the diagnosis meant to him. Looking back, the silence around his illness is what I grieve most.

We share the same genes, the same history, and many of the same habits. The outcomes, however, are not shared—and there’s no way to know which side of the line you’ll land on.

My younger brother just turned 60 and has been living with Alzheimer’s for several years. Before the disease, he was a successful, award-winning chef.
