John Jennings and his sister Emily face a 50:50 chance of developing early-onset Alzheimer’s Disease, following their mother Carol’s diagnosis at age 50. Despite the uncertainty, John prioritizes relationships over material possessions, fearing the loss of social connections if he inherits the faulty gene. Carol’s proactive approach to her condition led to groundbreaking research when she wrote to a team at University College London (UCL) in the 1980s. This led to the identification of a gene mutation linked to early-onset Alzheimer’s in their family. John and Emily now carry a 50% chance of inheriting the mutation, which could manifest around the same age as their mother’s diagnosis, causing them to live with the looming uncertainty of the condition.
