  • Anglais The Biology of Desire

    Marc Lewis

    The psychiatric establishment in the Western world has unanimously branded addiction a brain disease. And the idea that an addict has an incurable illness, as opposed to a contemptible moral weakness, has served an historically important role in changing how addiction is understood, researched, and treated throughout the world.
    But as renowned developmental neuroscientist and recovered addict Marc Lewis argues in this illuminating, compelling, likely controversial book, addiction is not in fact a disease. Addiction, whether to drugs, alcohol, gambling, food, sex, or cigarettes, is rather a developmental learning process resulting from the normal functioning of the human brain.
    Through vividly rendered, compassionate stories of five addicts, interpreted in the light of state-of-the-art neuroscientific knowledge, Lewis shows how the compulsion to use arises in a brain that is highly efficient in pursuing singular goals. He reveals addiction as an unfortunate twist of fate for a brain doing what it's designed to do seek pleasure and relief in a world that's not cooperating. He shows that recovery from addiction is indeed possible,and that it is nothing like remission from a disease, because brain physiology doesn't need to change for addicts to get better.
    The Biology of Desire is vital and enlightening reading for anyone who has wrestled with addiction themselves, in their families, or as a medical or treatment professional. It illuminates a path to more effective treatment for addicts, and limns the essential requirements for individual recovery. Combining clearly rendered scientific explanation with insight, compassion, and even humor, Lewis boldly challenges us all to re-examine our approach to addiction, and whether the metaphors we've used to explain it have now become obstacles to healing.

  • Marc Lewis's relationship with drugs began in a New England boarding school where, as a bullied and homesick fifteen-year-old, he made brief escapes from reality by way of cough medicine, alcohol, and marijuana. In Berkeley, California, in its hippie heyday, he found methamphetamine and LSD and heroin. He sniffed nitrous oxide in Malaysia and frequented Calcutta's opium dens. Ultimately, though, his journey took him where it takes most addicts: into a life of addiction, desperation, deception, and crime.But unlike most addicts, Lewis recovered and became a developmental psychologist and researcher in neuroscience. In Memoirs of an Addicted Brain, he applies his professional expertise to a study of his former self, using the story of his own journey through addiction to tell the universal story of addictions of every kind. He explains the neurological effects of a variety of powerful drugs, and shows how they speak to the brain itself designed to seek rewards and soothe pain in its own language. And he illuminates how craving overtakes the nervous system, sculpting a synaptic network dedicated to one goal more at the expense of everything else.
