Harvard professor loses memory at fifty
Alice Howland, a 50-year-old Harvard psycholinguistics professor, gets lost running in Harvard Square, a place she has known for decades, and is diagnosed with early-onset familial Alzheimer's caused by a dominant PSEN1 mutation. Her three adult children each face a 50% chance of inheriting it: Anna tests positive and uses IVF with embryo screening, Tom tests negative, and Lydia declines to know. Over about two years Alice loses her teaching post, her ability to read and recognize her daughter, and her place in her husband John's plans when he takes a job in New York.
