Dementia Reimagined

In 2019, Powell published Dementia Reimagined: Building a Life of Joy and Dignity from Beginning to End through Penguin Random House. Dementia Reimagined combines medicine and memoir, discussing both the history of dementia and Alzheimer's disease and the emotional and ethical issues involved in dealing with it in an elderly family member. One of the historical figures she discusses is Solomon Fuller, a black doctor whose research at the turn of the twentieth century anticipated important aspects of current medical knowledge about dementia.
