The Family That Couldn't Sleep: A Medical Mystery

For two hundred years a noble Venetian family has suffered from an inherited disease that strikes their members in middle age, stealing their sleep, eating holes in their brains, and ending their lives in a matter of months. In Papua New Guinea, a primitive tribe is nearly obliterated by a sickness whose chief symptom is uncontrollable laughter. What these strange conditions–kuru, scrapie, and mad cow disease–share is their cause: prions. Prions are ordinary proteins that sometimes go wrong, resulting in neurological illnesses that are always fatal. Even more mysterious and frightening, prions are almost impossible to destroy because they are not alive and have no DNA.In The Family That Couldn’t Sleep, essayist and journalist D. T. Max tells the spellbinding story of the prion’s hidden past and deadly future. Through exclusive interviews and original archival research, Max explains prion diseases’ connections to human greed and ambition–from the Prussian chemist Justus von Liebig, who made cattle meatier by feeding them the flesh of other cows, to New Guinean natives whose custom of eating the brains of the dead nearly wiped them out- and their impact in the world today. With precision, grace, and sympathy, Max explores maladies that have tormented humanity for centuries and gives reason to hope that someday cures will be found.
