After her father’s death from dementia, writer and campaigner Nicci Gerrard set out to explore the illness that now touches millions of us, yet which we still struggle to speak about. What does dementia mean for those who live with it, and those who care for them? The first section of Lavinia Greenlaw’s new poetry collection The Built Moment is a sequence of poems called The Sea is an Edge and an Ending, about her father’s dementia and his disappearance into the present tense. It is not a narrative of illness so much as a meditation on the metaphysics of memory and loss. Chaired by Rosie Boycott.
