This is a puzzling idea, for someone to become ‘not the same person any more’. The phrase smacks of philosophy – perhaps even obscurity. Yet it is simultaneously apt, capturing the emotive sense of no longer recognising someone whom we once knew. Many have witnessed someone they loved change so profoundly that the person remaining seems an entirely different one. Drug dependence powerfully exemplifies this phenomenon of not being the same person: a mother sees addiction transform her son into a shadow of his former self. Other examples can evoke the same feeling. A ruinous relationship or divorce leaves a friend so changed that he seems like a totally different person. So too can Alzheimer’s disease – which affects up to half of elderly Americans. A parent or relative develops severe Alzheimer’s, and it seems as if the person once known has disappeared. Across a range of experiences, profound changes can make well-known friends or family become entirely different people. T
