Addiction affects which part of the brain




















Other priorities, including job, family, and hobbies that once produced pleasure have trouble competing with this cycle. Healthy adults are usually able to control their impulses when necessary, because these impulses are balanced by the judgment and decision-making circuits of the prefrontal cortex. Unfortunately, these prefrontal circuits are also disrupted in substance use disorders.

This explains why substance use disorders are said to involve compromised self-control. It is not a complete loss of autonomy—addicted individuals are still accountable for their actions—but they are much less able to override the powerful drive to seek relief from withdrawal provided by alcohol or drugs.

At every turn, people with addictions who try to quit find their resolve challenged.

The more someone abuses a drug, the more they may continue using it unless they get help overcoming a life-threatening addiction. Once the chemical has affected the brain, individuals can feel physical symptoms as well as the impact of the chemical throughout their nervous system.

Symptoms can include a rapid heartbeat, paranoia, nausea, hallucinations, and other disturbing sensations the individual has little control over. He or she may become consumed with abusing the substance to maintain their habit no matter the cost. As a result of this powerful grip of substance abuse, individuals can begin acting in unrecognizable ways; this may concern friends and family. The brain regulates temperature, emotion, decision-making, breathing, and coordination. This major organ of the body also impacts physical sensations in the body, cravings, compulsions, and habits.

Under the influence of a powerful and harmful chemical, individuals abusing substances like Benzodiazepines or Heroin can alter the function of their brain. Individuals continue taking drugs to support the intense feel-good emotions the brain releases; this creates a cycle of drug use and intense highs. Eventually, they take the drug just to feel normal.

As a consequence of drug addiction, the brain rewards the harmful behavior. Once someone suddenly stops using, there are harsh mental, physical, and emotional results. Individuals may experience distressing symptoms they cannot ignore for some substances; withdrawal symptoms are generally stronger for some substances than others. At the point of withdrawal, someone who stops using Heroin experiences intense cravings, depression , anxiety , and sweating. Much of this is due to the rewiring of the brain after extended Heroin use.

In this stage, the individual may not have a full-blown addiction; a tolerance or dependency may have developed, however. Over time, the high volume of chemicals floods the brain; the brain correspondingly adapts to the mental effects of the substance. The brain then reduces its production of neurotransmitters, chemical messengers in the brain.

Withdrawal symptoms often need professional treatment, which can significantly help reduce the chance of relapse and the risks of stroke and heart attack. Learn More. The brain is often likened to an incredibly complex and intricate computer.

Instead of electrical circuits on the silicon chips that control our electronic devices, the brain consists of billions of cells, called neurons, which are organized into circuits and networks. Each neuron acts as a switch controlling the flow of information.

If a neuron receives enough signals from other neurons that it is connected to, it fires, sending its own signal on to other neurons in the circuit. The brain is made up of many parts with interconnected circuits that all work together as a team. Different brain circuits are responsible for coordinating and performing specific functions.

Networks of neurons send signals back and forth to each other and among different parts of the brain, the spinal cord, and nerves in the rest of the body the peripheral nervous system. To send a message, a neuron releases a neurotransmitter into the gap or synapse between it and the next cell. The neurotransmitter crosses the synapse and attaches to receptors on the receiving neuron, like a key into a lock. This causes changes in the receiving cell.

Other molecules called transporters recycle neurotransmitters that is, bring them back into the neuron that released them , thereby limiting or shutting off the signal between neurons. Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters.
