What are the Biomarkers of Addiction?

Biomarkers of addiction are biological measures that can indicate the presence or severity of the addiction.

Examples of biomarkers of addiction include:

  • Changes in brain structure and function.
  • Alterations in neurotransmitter systems.
  • Changes in gene expression.
  • Changes in levels of specific proteins or hormones.

Biomarkers can help understand the mechanisms underlying addiction. They help predict who may be at risk for developing addiction and monitor treatment progress. However, no single biomarker can definitively diagnose addiction, and a combination of clinical, behavioral, and biological measures is often used.

Biomarkers of Addiction Explained

Biomarkers of addiction can provide important information about the changes in the brain and body due to substance misuse.

Here are some examples of biomarkers of addiction and how they can affect addiction:

  • Changes in brain structure and function: 
    • Chronic drug use can cause structural and functional changes in the brain. This is particularly in regions involved in reward and motivation, such as the nucleus accumbens and the prefrontal cortex. These changes can affect the individual’s ability to experience pleasure and make decisions, contributing to continued substance misuse.
  • Alterations in neurotransmitter systems: 
    • Neurotransmitters are chemicals that transmit signals between neurons in the brain. Drugs can affect the levels and functioning of neurotransmitters.  These include dopamine, serotonin, and norepinephrine, which can contribute to the reinforcing effects of drugs and the development of addiction.
  • Changes in gene expression: 
    • Substance misuse can also cause changes in the expression of specific genes, which can alter the function of the brain and lead to addiction. For example, studies have shown that chronic drug use can cause epigenetic changes that affect the expression of genes involved in reward and stress response pathways.
  • Changes in levels of certain proteins or hormones: 
    • Substance misuse can also affect the levels of proteins or hormones in the body, contributing to addiction. For example, chronic alcohol use can increase stress hormones like cortisol, which can contribute to the development of alcohol dependence.

Reward and Motivation Changes

Biomarkers of addiction can provide important information about the changes in the brain and body due to substance misuse. Changes in brain structure and function, alterations in neurotransmitter systems, changes in gene expression, and changes in levels of specific proteins or hormones can all affect addiction by altering the brain’s reward and motivation pathways and affecting an individual’s ability to experience pleasure, make decisions, and manage stress. Understanding these biomarkers can help researchers and clinicians develop more effective treatments for addiction.

Yes, a person with a substance use disorder can potentially get tested for biomarkers related to their addiction. However, the specific biomarkers that can be tested may depend on the substance used, the test type, and the healthcare provider or facility offering the test.

Some examples of biomarker tests that may be available include blood or urine tests to detect drug metabolites, genetic tests to identify specific genetic variations that may affect addiction risk or treatment response, and imaging tests such as MRI or PET scans to examine brain structure and function changes.

It’s important to note that not all healthcare providers or facilities may offer biomarker testing for addiction and that biomarker testing alone is not typically enough to diagnose or treat addiction.

Instead, biomarker testing is usually done as part of a more extensive assessment considering a person’s symptoms, medical history, and other factors.

If you are concerned about a substance use disorder, talk to a healthcare provider who can help you determine the most appropriate next steps. They can decide if biomarker testing may be helpful in your specific case.

Questions to ask a Doctor or Insurance Company

Are you considering getting addiction biomarker testing? You can ask your medical professional or insurance provider several questions to determine if you are eligible and what the process will be like.

Here are some essential questions to consider:

  • What types of addiction biomarker tests are available?
  • Several types of biomarker tests are available for addiction, including genetic testing, imaging tests, and tests to measure hormone or neurotransmitter levels. Understanding what types of tests are available can help you determine which ones may be most relevant to your situation.
  • Will insurance cover the cost of addiction biomarker testing?
  • The cost of addiction biomarker testing can vary depending on the type of test, the provider, and your insurance coverage. It’s vital to understand whether insurance will cover the cost of testing and, if so, what your out-of-pocket costs may be.
  • What qualifications does the testing provider have?
  • Healthcare providers, including doctors, genetic counselors, and laboratory technicians, may perform addiction biomarker testing. Be sure to understand the qualifications and experience of the test provider.
  • How will the results of addiction biomarker testing be used?
  • Understanding how the results of addiction biomarker testing will be used can help you decide whether testing is appropriate for you. For example, suppose the results will inform treatment decisions or provide a more accurate risk assessment. In that case, testing is more valuable.
  • What are the potential risks and benefits of addiction biomarker testing?
  • Addiction biomarker testing may have benefits and risks like any medical test. Understanding these risks and benefits can help you decide whether testing is right.

Biomarker Testing Helps Treat Addictions
