How a rare genetic mutation could unlock new ways to treat or prevent dementia

Oct 2, 2026

Summary

Robert Kolker discusses his book *The Vanishing Family*, chronicling a Pennsylvania family affected by a rare genetic mutation causing frontotemporal dementia. The story highlights the disease's impact on personality and the family’s struggle with misdiagnosis and the burden of genetic testing. Kolker explains how studying this specific tau-related condition offers a potential pathway to developing treatments for broader dementias like Alzheimer’s.
