This episode features a neurologist with some striking tales to tell about who we become when our brains start to break. What happens when memories are gradually destroyed by Alzheimer's, when our personality is drastically transformed by dementia, or when a sudden surge of creativity is unleashed by Parkinson’s medication?

Dr Jules Montague’s new book Lost and Found integrates moving stories of her own patients with philosophical ideas about personal identity. The result is a fascinating insight into the fragile and complex workings of the brain, and a profound and compassionate reflection on the relationship between memory, personality and identity.
