Salimata “Sali” Zonon, 55, from Burkina Faso – but more recently, Brownsville – dipped her hand under the running faucet with a fist full of blueberries. She shook the berries dry and mixed them into a bowl of oatmeal. Across the room, Rita Asen, 94, laid her hand on her forehead as she sat at the kitchen table.

“On the days she doesn’t have dementia she eats very fast,” said Zonon, laying down the bowl of oatmeal and a cup of tea in front of Asen.
