How Does Addiction Impact Your Brain?

Lots of people may be familiar with how alcohol and drug addiction can impact a person’s behavior and decisions, but few fully understand how addiction affects the brain. How does addiction develop in the brain, and how do the chemicals in alcohol or drugs keep us addicted?

It’s first important to understand how the brain works. The brain is a major organ in our body that is in charge of maintaining temperature, emotions, coordination, breathing, and decision-making.

Thanks to scientific achievements, we are able to now know that people with drug or alcohol dependence display abnormal activity in the forebrain – the area where chemical messengers stimulate desire. This is because when someone develops an addiction, their brain considers the substance to be a reward and craves it more and more. When someone gives in and takes more drugs or consumes alcohol, the reward system is triggered and releases high levels of dopamine, a chemical that produces feelings of pleasure.

Once the chemicals in alcohol and drugs like stimulants, opioids, and sedatives enter the brain and bloodstream, people may also feel physical symptoms like nausea, paranoia, a rapid heartbeat, hallucinations, and more. However, people who have developed an addiction may be entirely focused on acquiring more of the “feel good” feelings from using drugs and will continue using, no matter how alarming or uncomfortable the symptoms may be.

What is the Long-Term Impact of Substance Abuse on the Brain?

When someone develops a tolerance to alcohol or drugs over time, the brain receptors adjust to the chemicals by producing less dopamine. As a result, the effects of euphoria and other symptoms might not feel as intense, and the user may feel the need to increase their dosage in order to replicate the intensity.

Because addiction is often a long-term struggle that can take years to overcome, it can also have long-term effects on the brain. Because alcohol and drugs affect areas of the brain that are responsible for emotions and motivation, over time, people can begin to lose their concentration and judgment.

Other long-term symptoms include:

  • Confusion
  • Feelings of lethargy or reduced motivation
  • Memory loss
  • Delayed reactions

How Withdrawal Affects the Brain

Withdrawal is unavoidable when people struggling with addiction suddenly stop using drugs or consuming alcohol. Some people experience unpleasant symptoms like sweating, nausea, and anxiety. Much of this occurs because after prolonged use, the drug has essentially rewired the brain. The brain has modified its neurotransmitter levels in order to achieve homeostasis; when someone stops using a drug, the homeostasis is thrown off. This imbalance creates issues with a person’s neurotransmitters and hormones, resulting in negative side effects.

Withdrawal can be dangerous and even life-threatening, depending on the drug and the level of addiction. This is why many people check into detox centers when they’re ready to stop using – withdrawal symptoms must be monitored by medical professionals, and often it can be harmful to stop using a drug all at once. A certified professional may suggest reducing use of the drug over time, rather than stopping altogether.
