From the Wellcome Prize-winning author of It's All in Your Head Brainstorm examines the stories of people whose symptoms are so strange even their doctor struggles to know how to solve them. A man who sees cartoon characters running across the room; a teenager who one day arrives home with inexplicably torn clothes; a girl whose world turns all Alice in Wonderland ; another who transforms into a ragdoll whenever she even thinks about moving. The brain is the most complex structure in the universe, and neurologists must puzzle out life-changing diagnoses from the tiniest of clues - it's the ultimate in medical detective work. In this riveting book, one of the UK's leading neurologists takes you with her as she follows the trail of her patients' symptoms: feelings of déjà vu lead us to a damaged hippocampus; spitting and fidgeting to the right temporal lobe; fear of movement to a brain tumour; a missed heart beat to the limbic system. It's a journey that will open your eyes to the unfathomable intricacies of the brain, and the infinite variety of human capacity and experience. Praise for It's All in Your Head 'As addictive as a great box set, makes you rethink some of your closest relationships and wonder about some of the people you know best; and above all, like all truly great books, it is about love and compassion' Satnam Sanghera, The Times 'Remarkable. It should be on the reading list of every medical student' P.D.
