A physician reflects on what this science means for the people we love. - Author: Cristiana Coneru - Tags: neuroscience, medical-technology, dementia-care, transcranial ultrasound stimulation, ultrasound brain therapy, Parkinson's disease ## *A physician's perspective on the intersection of cutting-edge neuroscience and the enduring power of hope* *This article is an updated and expanded version of a piece originally published on Substack, now revised with recent clinical research and updated medical citations.* **By Dr. Cristiana Coneru, MD, FRSM, FRCEM, CFMP, HCTP, Dip CNM, NBC-HWC Founder of Health Visioning** [www.healthvisioning.com](https://www.healthvisioning.com/?ref=cristianaconerumd.com) *New research on ultrasound brain therapy is offering real hope for dementia, Parkinson's, and even mood disorders. A physician reflects on what this science means for the people we love.* > "To love a person is to learn the song in their heart and sing it to them when they have forgotten." — Arne Garborg This world contains a great deal of suffering. I am not sure how many of you have spent time on a geriatric ward, but most of us have been through an Emergency Department at some point - whether as a patient, a visitor, or a clinician. If you have, you may have noticed the elderly patients in the corner beds: mumbling words that don't quite form sentences, their minds somewhere else entirely, their eyes searching for something no one in the room can provide. Completely alone, even when surrounded by people. It is one of the hardest things to witness as a clinician - watching someone who was once brilliant, once sharp and full of life, quietly fading into the fog. We feel that particular kind of helplessness that medicine doesn't prepare you for: the urge to reach in and pull them back, and the knowledge that you cannot. The damage, in most cases, was done long before the symptoms appeared - silently, over decades, without a single warning sign. We have protocols, nutritional plans, and medications. We do our best. But often, by the time we are involved, hope is the most powerful thing we have left to offer. --- ## **When the Song Is Forgotten** ![A close-up photograph of a younger person tenderly cradling and holding the weathered, wrinkled hands of an elderly individual against a soft, neutral grey background, conveying deep empathy, comfort, and care.](https://storage.ghost.io/c/6a/fc/6afcfd0f-a75c-4a8c-8913-92270490092e/content/images/2026/10/curated-lifestyle-hedibYakwmQ-unsplash-1.jpg) Think of the families. A daughter loses her mother - not to death, but to distance. The woman who raised her is still there, still breathing, still physically present, and yet entirely unreachable. There are no more conversations over tea. No more shared laughter over small things. No more of that particular smile. Her quiet wish - the one she carries everywhere - is simply to hear "I love you, my child" one more time. Or think of the teenage boy who adored his grandfather. They played chess together, built furniture together, talked late into the evening. Now the grandfather is somewhere the boy cannot follow, and the world keeps telling him that this is just how it goes. But the boy doesn't accept it. He keeps hoping, in the way that young people sometimes do, for what the world has labelled impossible. These are not edge cases. These are the stories that fill our wards and our waiting rooms. And in the middle of them, there is often only a thin thread of hope holding things together. What I want to tell you is that the thread is getting stronger - and it is getting stronger in more directions than just memory and movement. --- ## **A Quiet Revolution from Oxford** ![A 3D digital illustration of a metallic human brain centered within a complex, floating futuristic glass and digital ring targeting array, representing non-invasive focused ultrasound neuromodulation technology.](https://storage.ghost.io/c/6a/fc/6afcfd0f-a75c-4a8c-8913-92270490092e/content/images/2026/10/allison-saeng-aY0bNoQDJLY-unsplash-1.jpg) A remarkable piece of technology has recently emerged from the labs at the University of Oxford and University College London. Scientists have developed a helmet that uses sound waves to interact directly with the brain - and when I first read about it, my honest reaction was that it sounded like something out of science fiction. But this is real, peer-reviewed, published science. The system is built on Transcranial Ultrasound Stimulation (TUS). It uses a 256-element helmet-shaped transducer that delivers mechanical pulses - not heat, not electricity - to influence how neurons signal to one another. Crucially, it can target brain areas roughly 1,000 times smaller than conventional ultrasound technology allows ([Martin et al., 2025](https://doi.org/10.1038/s41467-025-63020-1?ref=cristianaconerumd.com)). That level of precision is genuinely unprecedented in non-invasive brain stimulation. It is worth being precise about what this particular study showed: the Oxford/UCL team demonstrated the technology in seven healthy volunteers, successfully and reproducibly modulating a small visual relay structure deep in the brain (the lateral geniculate nucleus) and the visual cortex connected to it ([Martin et al., 2025](https://doi.org/10.1038/s41467-025-63020-1?ref=cristianaconerumd.com)). It was a proof of concept for precision - not a completed Parkinson's or Alzheimer's trial. The researchers themselves have been clear that the clinical applications for conditions like Parkinson's disease are the next horizon, not something already demonstrated in this paper. That next horizon, encouragingly, already has a foothold. A separate team at the University of Toronto's Krembil Brain Institute has taken this kind of precision targeting directly into patients. In a 2025 study, researchers applied low-intensity theta-burst ultrasound to the globus pallidus internus - a deep basal ganglia structure - in ten people with Parkinson's disease or dystonia who already had deep brain stimulation (DBS) electrodes implanted, alongside fifteen healthy participants. Using personalized computational modeling to plan each person's stimulation individually, the ultrasound suppressed the pathological beta-band brain activity long associated with Parkinson's motor symptoms, effectively mimicking what conventional, surgically implanted DBS does - without opening the skull ([Darmani et al., 2025](https://doi.org/10.1038/s41467-025-57883-7?ref=cristianaconerumd.com)). This is not a hypothetical extension of the Oxford work; it is direct evidence, in real patients with movement disorders, that non-invasive ultrasound can reach and influence the exact deep-brain circuits that DBS surgery currently targets. For conditions like Parkinson's disease and Alzheimer's, which have long resisted conventional treatments, this kind of precision opens a door that has been firmly shut for decades. It is not simply about targeting a region of the brain - it is about reaching the right cluster of neurons, at the right depth, without touching anything else. Together, these two lines of research are proposing a fundamentally different way of thinking about what non-invasive neurological treatment can look like. --- ## **Sweeping Away the Inflammation - and the Debris** ![An abstract digital graphic of vibrant blue fluid ripples and concentric wave currents swirling tightly together, symbolizing acoustic pressure flushing away cellular debris and inflammation.](https://storage.ghost.io/c/6a/fc/6afcfd0f-a75c-4a8c-8913-92270490092e/content/images/2026/10/logan-voss-zU-hNrDHVfI-unsplash-1.jpg) To understand why this matters so deeply, it helps to understand what neuroinflammation actually does. It is, in many ways, the silent thief of cognitive life. When the brain's immune cells - called microglia - become chronically activated, they shift from their intended protective role into something more damaging: they release pro-inflammatory signals that erode the synaptic connections between neurons, contribute to cell death, and create the kind of persistent "brain fog" that many patients with neurological conditions describe. Left unchecked, this inflammatory environment paves the way for dementia and progressive impairment. This is where Low-Intensity Focused Ultrasound (LIFUS) becomes particularly interesting. Recent research has shown that LIFUS has neuroprotective effects - it can help shift the microglial environment, via the MAPK–NF-κB signaling pathway, back toward a state that supports neuron survival and preserves synaptic integrity after injury ([Hsiau et al., 2025](https://doi.org/10.1096/fj.202502379R?ref=cristianaconerumd.com)). Think of it as clearing a path that inflammation had blocked. Not a cure in itself, but a meaningful shift in the conditions under which the brain can begin to recover. Stanford researchers have taken this idea of "clearing the path" almost literally. In a 2025 study, a team led by Dr. Raag Airan used low-intensity focused ultrasound to help the brain flush out its own cerebrospinal fluid more effectively - physically encouraging the clearance of blood, debris, and inflammatory byproducts from the brains of mice after simulated hemorrhagic strokes. The treated mice showed reduced brain inflammation, less tissue damage, and better survival and functional recovery than untreated mice ([Azadian et al., 2025](https://doi.org/10.1038/s41587-025-02866-8?ref=cristianaconerumd.com)). It's an important caveat that this work is still in mice, not people - but the Stanford team has said they intend to begin human testing soon, and the underlying idea is compelling: rather than only quieting inflammation after the fact, this approach helps the brain's own waste-clearance system do its job. And the effects go beyond inflammation and debris. Low-Intensity Pulsed Ultrasound (LIPUS) - a related modality - has demonstrated the ability to pass through the skull entirely without surgery, reaching injured tissue and encouraging the formation of new synaptic connections ([Sharif, 2023](https://doi.org/10.1089/jop.2022.0046?ref=cristianaconerumd.com)). For years, the received wisdom in neurology was that once brain tissue was lost, it was gone permanently. Neurons, we were taught, do not regenerate in any meaningful way. That certainty has been quietly dissolving over the last decade, and this research is part of what's dissolving it. In a study examining vascular dementia in animal models, Low-Intensity Focused Ultrasound Stimulation improved working memory and overall cognitive function by creating a more hospitable neuronal environment - reducing inflammation, improving blood flow, and supporting the survival of existing neurons ([Wang et al., 2022](https://doi.org/10.3389/fnagi.2022.814560?ref=cristianaconerumd.com)). The mechanisms are becoming clearer. The results are beginning to accumulate. Something real is happening here. --- ## **Beyond Movement and Memory: A Quieter Kind of Suffering** ![An elegant, minimalist abstract digital graphic with a soft fluid gradient of warm peach and light blue tones, featuring a thin, delicate curve sweeping across a gentle background to represent calm emotional processing and deep-brain psychiatric care.](https://storage.ghost.io/c/6a/fc/6afcfd0f-a75c-4a8c-8913-92270490092e/content/images/2026/10/yue-ma-Yc6Ik-48C18-unsplash-1.jpg) I want to widen the lens for a moment, because not every family I think of in this article is grieving a parent's memory. Some are watching someone they love disappear into depression, anxiety, or the aftermath of trauma - a different kind of fog, but a fog all the same. Here too, ultrasound-based neuromodulation is showing early but genuine promise. Researchers at the University of Texas at Austin's Dell Medical School recently completed a pilot study using low-intensity transcranial focused ultrasound to target the amygdala - a deep brain structure central to fear, anxiety, and emotional processing - in 29 patients with mood, anxiety, and trauma-related disorders, alongside 23 healthy comparison participants. After a three-week course of daily treatment, patients showed statistically significant reductions in general psychological distress, along with meaningful improvements on measures of depression, anxiety, and PTSD symptoms, with a strong safety and tolerability profile throughout ([Barksdale et al., 2025](https://doi.org/10.1038/s41380-025-03033-w?ref=cristianaconerumd.com)). This was an early-phase, unblinded single-arm trial - the next step is a properly randomized, blinded study to confirm efficacy - but it is a real signal that the same precision-targeting principle reshaping how we think about Parkinson's and Alzheimer's may also open a gentler path for people whose suffering lives in mood and memory of a different kind. --- ## **When Science Meets the Human Story** ![An abstract 3D digital illustration of an organic neural branching structure glowing with cyan light filaments and warm golden nodes against a dark navy blue background, symbolizing the connection between advanced neuroscience and human stories.](https://storage.ghost.io/c/6a/fc/6afcfd0f-a75c-4a8c-8913-92270490092e/content/images/2026/10/getty-images-SLS9B0fEDRA-unsplash--5--1.jpg) I want to pause here, because science can sometimes feel remote - all mechanisms and pathways and statistically significant outcomes. But behind every study in this field, there is a very human question being asked: can we give someone back to the person who loves them? For those not personally affected by neurological disease, it is perhaps possible to engage with this research as an intellectual curiosity, a promising development in a specialised field. But for the patients living in the shadow of these conditions, and for the families beside them, this is not an abstraction. It is a roadmap toward something they thought they had lost permanently: dignity, connection, recognition. And the carers carry their own weight in all of this. The burnout, the isolation, the grief that doesn't have a clean name because the person is still alive - these are real and often invisible costs. Society tends to focus on the patient, but the person sitting vigil beside them, day after day, needs to be seen too. When a new treatment offers even a partial restoration of the person they knew, the relief is not just medical. It is existential. A physician must approach all of this with empathy. Science brings precision; medicine must also bring presence. What this new wave of research represents, at its best, is the possibility of both at once - a precision that is genuinely in service of the human being, not just the diagnosis. --- ## **A Daughter's Perspective** ![An intimate, shallow depth-of-field photograph of two white ceramic coffee cups on a table with a vintage film camera resting blurred in the background, metaphorically representing shared family moments and the preservation of fading memories.](https://storage.ghost.io/c/6a/fc/6afcfd0f-a75c-4a8c-8913-92270490092e/content/images/2026/10/henny-kasa-pbzO4sw29q8-unsplash-1.jpg) I am not, by nature, an enthusiast. I tend toward caution in my clinical thinking, and I have learned, sometimes painfully, not to promise more than medicine can deliver. Having encountered the reality of brain damage from both sides of the equation, as a physician and as a daughter, this research once stirred something unusual in me: hope. Not certainty, not expectation, but the quiet possibility that recovery might one day reach those we love. My mother's journey has since come to an end. Yet I find that my response to this research has not disappeared entirely. The hope I once carried for her has evolved into something else: gratitude for every scientific step forward, compassion for the families still walking this path, and a deep appreciation for the resilience of the human spirit in the face of profound loss. When I close my eyes, I can still picture my mama. I can feel the wind. I can smell the acacia flowers. I can see my mama coming toward me with that particular smile, the one that belonged only to her. For a long time, I imagined her walking through the park again, moving freely beneath the trees. My mind visited that place a thousand times, holding on to hope through the difficult months that followed. She left this world not long ago. The walk I imagined never came to be. Yet the image remains, not as a reminder of what was lost, but of who she truly was. When I think of her now, I do not think of hospitals, illness, or the wheelchair she needed during her final months. I remember her smile, her strength, and the love she gave so freely. In my heart, she is still walking toward me through the scent of acacia blossoms, forever herself, forever loved, and forever beyond pain. *I know that is not a clinical observation. But I also think it matters. Medicine that loses sight of what it is trying to restore, not just function, but personhood, relationship, and the texture of a shared life, has lost something essential. My mother is no longer here. Yet reading this research, I still think of her. I think of all the moments illness steals, and all the moments families hope to reclaim.* *The promise of ultrasound-based neurotherapy is not simply that it may change a scan or improve a score. It is that it may help preserve the things that matter most: conversations, recognisable smiles, shared memories, and the connections that make us who we are.* *For me, this research is no longer about bringing my mother back. That chapter has ended. But if it helps another daughter spend more time with her mother, another family hold on to hope a little longer, then it represents something profoundly meaningful.* *And that, perhaps, is reason enough to keep moving forward.* --- ## **Where We Are, and Where This Is Going** ![A conceptual horizontal motion-blur photograph of a calm seascape at dawn, featuring deep indigo and blue tones transitioning into a radiant amber horizon, symbolically representing the forward-looking roadmap and bright future of global neurological medicine.](https://storage.ghost.io/c/6a/fc/6afcfd0f-a75c-4a8c-8913-92270490092e/content/images/2026/10/lucas-davies-cMlhripX2Ao-unsplash-1.jpg) It is important to be honest about where this research currently stands, because the stages differ significantly from study to study. The Oxford/UCL helmet has, so far, been tested for precision targeting in healthy volunteers, not in patients ([Martin et al., 2025](https://doi.org/10.1038/s41467-025-63020-1?ref=cristianaconerumd.com)). The Toronto team's Parkinson's work has been tested directly in patients, but in a small pilot cohort using existing DBS hardware to measure the effect, not yet as a standalone outpatient therapy ([Darmani et al., 2025](https://doi.org/10.1038/s41467-025-57883-7?ref=cristianaconerumd.com)). The Stanford debris-clearance work remains in animal models ([Azadian et al., 2025](https://doi.org/10.1038/s41587-025-02866-8?ref=cristianaconerumd.com)). The mood and anxiety pilot at UT Austin was in real patients, but unblinded and awaiting a larger controlled follow-up ([Barksdale et al., 2025](https://doi.org/10.1038/s41380-025-03033-w?ref=cristianaconerumd.com)). And the LIFUS and LIPUS inflammation and neuroplasticity research spans both animal models and early human work ([Hsiau et al., 2025](https://doi.org/10.1096/fj.202502379R?ref=cristianaconerumd.com); [Sharif, 2023](https://doi.org/10.1089/jop.2022.0046?ref=cristianaconerumd.com); [Wang et al., 2022](https://doi.org/10.3389/fnagi.2022.814560?ref=cristianaconerumd.com)). We are not yet at the point where a neurologist or psychiatrist can prescribe an ultrasound session the way they might prescribe a medication. The path from promising research to standard clinical care is long, and it should be - because the stakes are high and the patients are vulnerable. But the direction of travel is clear, and it is hopeful. The convergence of high-precision targeting technology, direct evidence in Parkinson's patients, anti-inflammatory and debris-clearing mechanisms, neuroplasticity research, and now early evidence in mood and trauma disorders is building a picture that is harder and harder to dismiss. Non-invasive, sound-based neurotherapy is moving from the edges of the field toward something that looks increasingly like a genuine clinical frontier. For those of us who have sat with patients in the fog, or beside them as family members, that movement - however gradual - is not a small thing. --- ## **A Gentle Opening into Tomorrow** ![An abstract 3D digital illustration of flowing, glossy teal and amber glass-like ribbons splitting apart in the center to reveal an open background, representing the safe and temporary opening of the blood-brain barrier.](https://storage.ghost.io/c/6a/fc/6afcfd0f-a75c-4a8c-8913-92270490092e/content/images/2026/10/a-c--VBW9oLgLm8-unsplash-1.jpg) Healing tends to happen quietly. It rarely announces itself. It comes in the small moments - a flicker of recognition, a word retrieved from somewhere, a smile that belongs to the person you remember. Recovery of this kind is not just a medical process. It is a human quest: to find the person who was lost, and to bring them home. If you find yourself somewhere in this story - whether as a clinician, a carer, a patient, or simply someone who loves a person living in the fog - you are not alone. The research is moving. The technology is developing. The question that has always driven the best of medicine - how do we help people get back to themselves? - is being asked now with tools that did not exist a decade ago. That is worth holding onto. Not as false comfort, but as the real and careful thing that it is: evidence that the door is not as permanently closed as it once appeared. > "Sometimes beautiful things come into our lives out of nowhere… sometimes it pays to just have a little faith." — Lauren Kate --- ## **Frequently Asked Questions** **What is transcranial ultrasound stimulation (TUS)?** TUS is a non-invasive brain stimulation technique that uses focused, low-intensity sound waves - not heat, electricity, or surgery - to influence how neurons communicate. It can reach deep brain structures that other non-invasive methods, like transcranial magnetic stimulation, cannot access. **Is ultrasound brain therapy available to patients right now?** No. As of this writing, the research described here spans healthy-volunteer studies, small patient pilot trials, and animal models. None of it has yet become an approved, prescribable clinical treatment. Larger, randomized, controlled trials are the necessary next step for each of these applications. **Which conditions is this research targeting?** The studies discussed here involve Parkinson's disease, Alzheimer's disease and related dementias, recovery from hemorrhagic stroke and traumatic brain injury, and mood, anxiety, and trauma-related disorders including depression and PTSD. **Is this the same thing as deep brain stimulation (DBS) surgery?** No, though the goal is similar. DBS requires surgically implanting electrodes into the brain. Transcranial ultrasound aims to achieve comparable, targeted effects on deep brain circuits without any surgery. **Where can I read the original research?** Full citations and links to each peer-reviewed study are listed in the references below. --- ****BIOLOGICAL ASSESSMENT** ****What Is Your Baseline Inflammation Score?** While ultrasound works on deep neurological debris in the lab, low-grade systemic inflammation impacts your body daily.
