If you’ve ever had one of those moments where you read a scientific article and thought, “I might need a translator,” welcome to my brain’s reaction to Stanford Medicine’s deep dive into the relationship between addiction and myelin. Myelin, for the uninitiated (or, in my case, the terminally confused), is described in the article as “the fatty insulation that coats nerve fibers, allowing them to transmit electrical signals efficiently.” Basically, it’s the bubble wrap around our neurons, keeping our brain signals running smoothly—until addiction starts tearing through the packaging like a toddler at Christmas.
The article explains that chronic opioid use “damages myelin, impairing communication between brain regions and contributing to addiction-related behaviors.” It’s fascinating, terrifying, and makes me incredibly grateful that opioids weren’t my poison of choice. Honestly, my avoidance of opioids feels less like a noble act of willpower and more like dumb luck. I just happened to fall in love with uppers—the buzzing, chaotic kind of love that ruins your credit score and makes your friends stage interventions.
But let’s not get distracted by my personal journey of caffeinated heartbreak. This research is groundbreaking because it reveals just how deeply addiction rewires our brains, quite literally eating away at the structures that make us who we are. According to the study, “impaired myelin leads to disrupted communication in the brain’s reward system, making it harder for individuals to resist cravings and make healthy decisions.” So, in essence, addiction doesn’t just hijack your brain—it dismantles the wiring and replaces it with a haunted funhouse of bad decisions.
Now, full disclosure: I don’t understand half the science in this article. There are parts where they talk about “oligodendrocytes” and “myelin sheath integrity,” and my brain just nods politely while secretly Googling, “What the hell is an oligodendrocyte?” Thankfully, I don’t need to fully grasp the mechanics to appreciate the takeaway: addiction is a disease, not a moral failing, and it physically alters the brain in ways we’re only beginning to understand.
The article also touches on how this research could lead to better treatments. One approach involves “promoting myelin repair to help restore normal brain function.” This is where I imagine a tiny crew of construction workers inside my head, patching up the wreckage and saying things like, “We’re gonna need more insulation on that prefrontal cortex.”
But here’s the thing that really hit home for me: addiction is not a one-size-fits-all monster. For some, it’s opioids; for me, it was uppers and alcohol. The substances may vary, but the underlying damage—the way addiction rewires your brain and your life—is universal. It’s why we need to approach recovery with the same complexity and nuance that science is finally starting to uncover.
I also love how this article doesn’t shy away from the human element. As Stanford researcher Anna Molofsky says, “Understanding the role of myelin gives us a new way to think about addiction—not just as a behavioral problem, but as a structural one.” It’s a reminder that addiction isn’t just about willpower; it’s about biology, environment, and a thousand other factors we’re only beginning to map out.
Reading this made me think about how easy it is to fall into the trap of thinking you’re in control, only to realize that control was an illusion all along. Addiction doesn’t care if you’re smart, strong, or self-aware—it’s an equal-opportunity brain-wrecker. And while I’m lucky to be on the other side of my battle, articles like this remind me just how thin the line between luck and disaster can be.

And if all this talk of damaged myelin and haunted funhouses of bad decisions makes you curious about how a brain like mine churns out novels, check out Demons Within, Cocaine Cola, The Dish Pit, and Serpents in the Sand. Links are somewhere on this blog, or in my Instagram bio @millprites. Who knows—maybe my brain’s wiring is weird enough to make fiction the perfect therapy.
