Perminder Sachdev explores the complexity of the human brain through ten fascinating case-studies from the neuropsychiatric clinic. From alien hand syndrome, anorexia nervosa, frontal lobe dysfunction and phantom limb to coprolalia in Tourettes Syndrome, dementia and golfer's cramp, he provides an understanding of how each disorder has been conceptualised and treated and the challenges that it poses for both the neuropshychiatrist and his patient.
