On a Saturday morning before the pandemic hit, when people still gathered indoors, adults of all ages filled a meeting room at a senior center in West Los Angeles. A few were young adults, some were older seniors, most were in late middle-age. The majority were women, but there were a few men, too. They grabbed coffees and muffins and quietly found a seat at one of several round banquet tables. The room was quiet at first, but it soon became almost raucous with conversation. Though they came from different walks of life, these strangers had at least one thing in common: Each cared for a family member or friend with dementia.
