Understanding Addiction How Addiction Hijacks the Brain Addiction involves craving for something intensely, loss of control over its use, and continuing involvement with it despite adverse consequences. Addiction changes the brain, first by subverting the way it registers pleasure and then by corrupting other normal drives such as learning and motivation.
Although breaking an addiction is tough, it can be done. Addiction exerts a long and powerful influence on the brain that manifests in three distinct ways: For many years, experts believed that only alcohol and powerful drugs could cause addiction. Neuroimaging technologies and more recent research, however, have shown that certain pleasurable activities, such as gambling, shopping, and sex, can also co-opt the brain.
Although a standard U. New insights into a common problem Nobody starts out intending to develop an addiction, but many people get caught in its snare.
Consider the latest government statistics: Nearly 23 million Americans—almost one in 10—are addicted to alcohol or other drugs. More than two-thirds of people with addiction abuse alcohol. The top three drugs causing addiction are marijuana, opioid narcotic pain relievers, and cocaine.
In the s, when researchers first began to investigate what caused addictive behavior, they believed that people who developed addictions were somehow morally flawed or lacking in willpower.
Overcoming addiction, they thought, involved punishing miscreants or, alternately, encouraging them to muster the will to break a habit. The scientific consensus has changed since then. Today we recognize addiction as a chronic disease that changes both brain structure and function.
Just as cardiovascular disease damages the heart and diabetes impairs the pancreas, addiction hijacks the brain. This happens as the brain goes through a series of changes, beginning with recognition of pleasure and ending with a drive toward compulsive behavior. Pleasure principle The brain registers all pleasures in the same way, whether they originate with a psychoactive drug, a monetary reward, a sexual encounter, or a satisfying meal.
In the brain, pleasure has a distinct signature: All drugs of abuse, from nicotine to heroin, cause a particularly powerful surge of dopamine in the nucleus accumbens. The likelihood that the use of a drug or participation in a rewarding activity will lead to addiction is directly linked to the speed with which it promotes dopamine release, the intensity of that release, and the reliability of that release.
Even taking the same drug through different methods of administration can influence how likely it is to lead to addiction. Smoking a drug or injecting it intravenously, as opposed to swallowing it as a pill, for example, generally produces a faster, stronger dopamine signal and is more likely to lead to drug misuse.
The hippocampus lays down memories of this rapid sense of satisfaction, and the amygdala creates a conditioned response to certain stimuli. Learning process Scientists once believed that the experience of pleasure alone was enough to prompt people to continue seeking an addictive substance or activity.
But more recent research suggests that the situation is more complicated. Dopamine not only contributes to the experience of pleasure, but also plays a role in learning and memory—two key elements in the transition from liking something to becoming addicted to it.Understanding alcohol abuse and alcoholism can be a key step in solving drinking problems.
