How do we know when it starts? How to differentiate dementia from climbing the stairs to retrieve something, but being unable to remember what? Do we declare an onset of Alzheimer’s after forgetting a famous face (you know, what’s his name?). It’s a dim boundary, but at some point our neurons struggle to recalibrate. The cortex and hippocampus are irrevocably changed. In memory loss, there is already death. Cells die and each one is a divesting of some part of the past. The cortex shrinks where the cells used to be. The spaces in between expand. Islands in the sea of the mind. An archipelago of the former self.
