Unraveling the Dance of Addiction: How Substance Use Reshapes the Brain at the Genetic Level

From Behavioral Health Business by Chris Larson

When gene activity fluctuates, it alters the proteins produced by your cells. These changes can influence anything from a single connection in your brain to your behavior. It's like a sophisticated genetic ballet - your genes influence your brain development, but they're also flexible, adapting to your learning and daily needs.

"Recent studies on animal models hint that addictive substances like alcohol and drugs may trigger changes in gene expression in brain regions responsible for memory and reward responses," says an expert in the field.

In every neuron, the way DNA is wound around proteins like histones regulates gene expression, thereby determining the proteins produced. Addiction can tweak gene expression in many ways, including altering the DNA-binding proteins, modifying how DNA is interpreted into proteins, and even changing the energy-using processes of cells.

For instance, alcohol can prompt an alternate gene form to be expressed in memory circuits in both flies and humans, causing alterations in dopamine receptors and transcription factors involved in reward signaling and neuronal function. The same can be said for cocaine's effects on mice's reward centers. The exact mechanism of how these substances alter gene regulation still remains an enigma, but there's some evidence that alcohol consumption could influence gene expression in mice.
These substances also ignite vital signaling pathways that are prominent regulators of metabolism, implying they can impact numerous aspects of neuronal function and therefore gene expression.

"Your lifestyle choices and the substances you consume can affect gene expression, but these changes aren't necessarily permanent. They can also be modified by medication and lifestyle habits," an expert explains.

Medication for mental health disorders, like antidepressants and mood stabilizers, can alter gene expression. For example, escitalopram, a commonly prescribed drug for depression, can adjust the winding of DNA and change the expression of brain plasticity-related genes.
Lifestyle choices can also affect gene expression. For example, a high sugar diet in flies can manipulate taste by manipulating gene expression. Intensive meditation can modify gene regulation in the brain, and exercise can change gene expression, promoting learning, memory, and potentially reducing dementia risk.

Virtual care can play a pivotal role in supporting these solutions. It offers a platform to keep patients engaged with their treatment, provides access to important resources such as health professionals and educational materials, and enables one-on-one virtual sessions for coaching, diet, exercise, meditation, and more. InterAct LifeLine's virtual care solutions are designed with these needs in mind, providing comprehensive support for those looking to optimize their brain health.

Here are some proposed solutions to positively influence brain health:

  1. Reducing consumption of addictive substances.
  2. Regular physical exercises.
  3. Positive dietary changes.
  4. Incorporating meditation into daily routine.
  5. Use of prescribed medications for mental health disorders.
  6. Exploring mRNA-based therapies.
  7. Attending therapy and counseling sessions.

As we move forward, it's crucial to remember that our choices can profoundly affect our brain biology. By reducing alcohol and drug consumption and adopting healthier lifestyle practices, we can stabilize and potentially improve our physical and mental health. It's your genes - they deserve your attention.
