A powerful podcast that gives clear insight into whether or not there should be genetic testing, and how one family copes with the diagnosis that may be hiding in their genes.

Tremolo is told from the perspective of Harri, a caring teenage boy. Like many young people who have just finished their A-levels, Harri is excited about the future: travelling  Europe by train with his friend, then going to niversity to pursue his dream of becoming a neurosurgeon. But his world is turned upside down instantly when his mother is diagnosed with eFAD – early onset Familial Alzheimer's Disease. In terms of genetics, there is a 50% chance that he and Gwenllian, his younger sister, could also develop the condition. This powerful podcast drama explores the impact of this cruel condition on family relationships, financial pressures, everyday life, and hope for the future.

Featuring an award-winning performance from Gareth Elis, winner of the Marc Beeby Award at the BBC Audio Drama Awards 2023 for his work on this powerful audio drama.
