Dementia often brings hidden truths to the surface, revealing deep-seated emotions and memories that may have been forgotten or suppressed. This condition acts like a "truth serum," allowing individuals to express their feelings and thoughts, sometimes leading to moments of clarity amidst the confusion of the disease. This phenomenon can have profound implications for understanding a person's life and experiences, offering insights into their past relationships and regrets.

In "The Bonesetter's Daughter," Amy Tan explores how dementia can impact family dynamics and reveal truths about identity and heritage. The complex layers of familial connections come forward as characters navigate the challenges posed by the illness, prompting them to confront their own feelings and the histories that shape them. Tan illustrates how such experiences can foster empathy, connection, and ultimately foster healing in the face of loss and memory struggles.
