Could Magnetic Brain Stimulation Help Tinnitus and TBI Survivors? Our Research Into Emerging Therapies
When you live with a brain injury long enough you become curious about anything that might explain what is actually happening inside your head. Not because you're looking for some miracle cure, but because so many of the symptoms we live with don't seem to fit neatly into the boxes traditional medicine gives us.
At Project TBI, I spend a lot of time researching those questions. Recently, I came across a technology called single-pulse transcranial magnetic stimulation, or sTMS, a non-invasive form of magnetic brain stimulation that has primarily been used for migraine treatment. One company working with this technology is eNeura, which has published clinical research around migraine treatment and prevention.
That caught my attention because headaches and migraines are obviously common after traumatic brain injury, but they rarely travel alone. Many of us also deal with tinnitus, light sensitivity, sensory overload, sleep problems, difficulty concentrating, cognitive fatigue and that strange feeling that the brain simply isn't regulating information the way it once did.
So naturally, I started wondering whether there might eventually be a connection.
Could magnetic stimulation someday help with some of the neurological symptoms that follow traumatic brain injury?
To be clear, I am not a doctor, Project TBI isn't providing medical advice, and I'm certainly not suggesting that sTMS is a proven treatment for TBI or tinnitus. It isn't. I'm simply a brain injury survivor who has become fascinated with how the brain works, what happens when it gets injured, and what researchers are learning about helping it recover.
What Is Magnetic Brain Stimulation?
The basic idea behind TMS is actually pretty fascinating. Our brains function through an incredibly complicated combination of electrical and chemical activity. Transcranial magnetic stimulation uses magnetic fields outside the skull to influence electrical activity within specific areas of the brain. Nothing is implanted and there is no surgery involved.
There are also different forms of TMS, and that distinction is important. Single-pulse TMS isn't the same thing as repetitive TMS, or rTMS, which delivers repeated magnetic pulses and has been studied for a much wider range of neurological and psychiatric conditions.
What interests me isn't necessarily one particular machine. It's the larger concept behind the technology.
If an injury changes the way different parts of the brain communicate with each other, could carefully targeted stimulation someday help influence those networks?
That becomes particularly interesting when you start thinking about tinnitus.
The Tinnitus Question
Anyone who lives with tinnitus knows how difficult it is to describe to somebody who doesn't have it. There can be absolutely nothing making noise around you, yet you're still hearing something.
Ringing. Buzzing. Humming. Sometimes something that almost sounds electrical.
The sound isn't necessarily coming from the outside world, which means somewhere along the auditory pathway the brain is creating, amplifying or interpreting a signal as sound.
Researchers have experimented with repetitive TMS targeting areas involved in auditory processing, and the results have been interesting but mixed. Some people have reported reductions in tinnitus severity while others haven't experienced meaningful improvement. That certainly doesn't make TMS a cure for tinnitus, and the sTMS technology that originally led me down this rabbit hole isn't specifically cleared as a tinnitus treatment.
But I still think the research raises an important question.
When someone experiences tinnitus after a brain injury, are we dealing with a problem in the ear, a problem in the brain, or a disruption somewhere within the entire system connecting the two?
The answer may be different from person to person, but that broader way of thinking about the problem is what I find interesting.
TBI Doesn't Happen in Separate Boxes
One of the biggest things I've learned from living with brain injury is that symptoms don't necessarily exist independently from one another.
You don't wake up and experience your tinnitus at 9:00, your cognitive fatigue at 11:00, your sensory processing problems after lunch and your headache at 3:00.
You experience all of it through the same injured brain.
A noisy environment can increase fatigue. Fatigue can make it harder to process sound. Struggling to process sound can require more concentration. More concentration consumes more cognitive energy, and eventually the whole system can become overwhelmed.
From the outside, those might look like completely different symptoms. From inside the brain injury, they can feel very much connected.
Medicine understandably separates symptoms so specialists can diagnose and treat them, but neuroscience is increasingly giving us ways to think about the brain as interconnected networks rather than a collection of isolated parts. That's why technologies involving neuromodulation interest me.
The question becomes bigger than simply, "Can we make this symptom go away?"
Maybe another question is, "What changed in the system that is producing the symptom in the first place?"
Where This Could Eventually Lead
I don't believe there is going to be one magic treatment for traumatic brain injury. The brain is simply too complicated, and brain injuries are too different from one person to another.
What I do believe is that the future of TBI recovery may look very different from the past.
We're learning more about neuroplasticity, sleep, exercise, sensory processing, nutrition, meditation, neurofeedback, electrical signaling and the ways different brain networks communicate with each other. Magnetic stimulation belongs somewhere in that larger conversation, even if we don't yet know exactly where.
Some of these approaches will eventually prove valuable. Others won't. Some may work incredibly well for one survivor and do almost nothing for another. That's the nature of studying something as complicated as the human brain.
For now, I see magnetic brain stimulation as something worth watching rather than something worth declaring.
And maybe that's an important distinction.
Project TBI isn't about chasing miracle cures or giving people false hope. It's about survivors being willing to ask questions, look at the research, compare it with lived experience and continue following the science as our understanding of brain injury evolves.
Because if living with TBI has taught me anything, it's how much we still don't understand about the brain.
And every time researchers figure out another small piece of that puzzle, we understand ourselves a little better too.
If you've personally tried TMS, neurofeedback, tinnitus therapy or another treatment after concussion or traumatic brain injury, I'd genuinely like to hear what happened. Not only the success stories, either. Sometimes learning what didn't work is every bit as valuable as learning what did.
That's how survivors help survivors.
