17-43 Segment 1: The Biology of Addiction

 

Addiction has become undoubtedly entangled in modern American society. Whether it’s gambling, food, sex, technology, alcohol or drugs, the deadly disease hijacks the human brain with severe ramifications. Recent eruptions in the number of opiate addicts and overdoses has shined an even brighter spotlight on this critical public health issue.

There is an inclination to equate addiction to a moral failing, lack of willpower, or simply bad judgment. Dr. Rita Goldstein, Professor of Psychiatry and Neuroscience at the Icahn School of Medicine at Mount Sinai, explains that due to our ‘evolutionary legacy,’ the reward center in the brain is designed to make us feel good when we do things like eat food or have sex. Yet, with prolonged addiction, a chemical imbalance occurs, and as a result, the reward center takes priority over rational thinking or the threat of negative consequence. When addictive behavior is continually reinforced, further imbalance occurs, weakening the part of the brain meant to counterbalance impulsive behavior.   

The good news; Dr. Anna Rose Childress, Research Professor of Psychology in Psychiatry at the Pennsylvania School of Medicine, observes that with abstinence, with or without the use of medications for recovering addicts, the brain can begin rewiring pathways created in the midst of addiction. The road to recovery is not yet paved in the golden promise of a cure, but understanding the biology of addiction is a critical component of treating the disease.

The Biology of Addiction

Scientists are learning the specific workings of the brain when it is addicted to a substance or behavior, and showing that all addictions are similar. This gives hope of one day developing a drug to combat many addictions. However, the stigma of addictions—that they are a moral failing—still looms over the field.

Preparing for Disaster

Many people will have to deal with a natural disaster at some point in their lives. Two civil defense experts discuss how to be ready before it comes.

Americans consume 80 percent of the opioid painkillers prescribed worldwide, ultimately resulting in the deaths of more than 20,000 Americans each year of overdoses of these drugs. The crisis is making doctors look at alternative medicine therapies for a substitute for these drugs. Experts discuss modalities that have shown success.
