Shocking Vagus Nerve Stimulation Could Rewire the Injured Brain

In 2025, the New York Times reported on a neuroscientist who has likened the vagus nerve to “a brake system in your car.” A May 18, 2026 New York Times piece, though, explored whether vagus nerve stimulation (VNS) can genuinely improve health or is simply a “scam”. This has brought renewed attention to a therapy that researchers have been quietly refining for decades; as the vagus nerve, a sprawling cranial nerve connecting the brain to major organs, has become one of neuroscience’s most compelling therapeutic targets, particularly in brain injury recovery.

For years, researchers in various institutions have demonstrated a direct connection between the VNS and the brain’s learning centers. Almost 4 years ago, University of Colorado Anschutz Medical Campus findings discovered that this connection may lead to treatments improving cognitive retention in both healthy and injured nervous systems. Senior author Cristin Welle, Ph.D., stated: “We concluded that there is a direct connection between the vagus nerve, the cholinergic system that regulates certain aspects of brain function, and motor cortex neurons that are essential in learning new skills.” A 2025 observational study available in the NIH database, and published in Frontiers in Neurology, found that non-invasive VNS was associated with reduced neuroinflammation and recovery in patients with mild traumatic brain injury experiencing persistent post-concussion symptoms.

VNS is also established as a treatment for drug-resistant epilepsy, a condition that can follow traumatic brain injury. However, a 2026 review drawing on PubMed data found that airway-related side effects such as hoarseness, cough, and shortness of breath were the most common reactions, with most resolving after adjustments to stimulation settings. A 2025 meta-analysis confirmed that complications from implanted VNS are generally mild and transient, with adverse events decreasing over time. Researchers continue urging caution, noting that larger randomized trials are still needed before VNS becomes a standard of care for brain injury rehabilitation.

No Congressional Urge to Move BACK HOME

An estimated 107,400 veterans are serving time in state or federal prison, many of whom may carry wounds that no one can see. Combat exposure-associated mental and physical consequences including traumatic brain injury, PTSD, and mood disorders, are unfortunately directly linked to a greater likelihood of criminal justice involvement among veterans. Currently, by law, the VA cannot provide hospital or outpatient care to incarcerated veterans because penal institutions are legally obligated to furnish inmate healthcare. Bipartisan legislation aims to break that cycle.

The Get Justice-Involved Veterans Behavioral Assistance and Care for Key Health Outcomes to Maintain Empowerment (BACK HOME) Act, was introduced by Senators Angus King (ME) and Pete Ricketts (NE), along with Representatives Herb Conaway (NJ) and Morgan Luttrell (TX). The bill, S. 4162 and H.R. 8044, would create a VA pilot program to furnish mental health services to incarcerated veterans, prioritizing those with service-connected TBI, PTSD, or military sexual trauma. It would also ensure automatic resumption of disability compensation payments upon a veteran’s release from incarceration.

“The Get Justice-Involved Veterans BACK HOME Act is about closing a dangerous gap in care by ensuring that justice-involved veterans can still access the mental health services they need to heal, rebuild, and successfully reenter their communities,” said Senator King. Congressman Conaway, a physician himself, added: “The Get Justice-Involved Veterans BACK HOME Act is about closing a dangerous gap in care by ensuring that justice-involved veterans can still access the mental health services they need to heal, rebuild, and successfully reenter their communities.”

The legislation is supported by the American Legion, Vietnam Veterans of America, the American Psychological Association, and the American Psychiatric Association.  Unfortunately, there has been no action on either the Senate or House BACK HOME Acts since their respective  introductions on March 23, 2026, and March 24, 2026.

NE Joins States to Promote Veteran Brain Injury Bill – Congress Has Run Out of Excuses

Legislative Resolution 314 on hyperbaric oxygen therapy with Nebraska Capitol building in background

On April 9, 2026, Nebraska’s Legislature passed Legislative Resolution 293 in a 43-0 vote, making it the 14th state – alongside Oklahoma, Texas, Indiana, Kentucky, Arizona, Florida, North Carolina, Wyoming, Maryland, Virginia, North Dakota, Tennessee and Missouri – to formally urge Congress to expand treatment access for veterans suffering from traumatic brain injury and post-traumatic stress disorder, one of the most pressing issues facing American veterans.

Introduced by Nebraska State Senator Kathleen Kauth, the resolution, “[urges] the United States Congress to swiftly enact legislation to provide for veterans’ access to treatments for traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD).”

In particular, states’ resolutions seek to encourage Congress to move forward on hyperbaric oxygen therapy. “A 4-week course of HBOT may alleviate depressive symptoms in PTSD patients, an effect associated with increased serum BDNF and β-NGF levels,” according to a 2026 study, available to view on the NLM database. The United States loses more than 17 veterans per day to suicide, with TBI and PTSD among the leading contributing factors.

Now that 14 states are aligned behind this legislation, the pressure on Congress to act is mounting.

Recovery Benefits of Golf Par for the Course

The 2026 PGA Championship is now underway in Charlotte, North Carolina. This annual event is, “known for having one of the strongest fields in golf,” according to an AI Overview. It also brings attention to the connection between golf and brain injury, as golf can be used for therapeutic means of recovery. Much like every other sport, though, playing golf can also be perilous, increasingly so in recent years, as golf becomes more physically demanding.

On the therapeutic side, golf provides exercise that can be beneficial for hand-eye coordination: bilateral coordination, fine motor grip retraining, postural balance, and visuospatial focus. The option of golf carts as an ambulation asset also provides exercise that can aid with balance deficits. Physical therapists call it, “a great training tool for the brain and the body to rehabilitate.” Programs such as Saving Strokes – launched in Sacramento more than a decade ago and now running at more than twenty sites across the western United States – use the golf swing as a neuroplasticity workout, recruiting both sides of the brain and body to rebuild balance, timing, and grip. Additionally, and just as importantly, it also allows for social engagement, which can reduce depression.

However, as with every other physical sport, golf can also be dangerous. In October 2025, the New York State Golf Association reported that approximately 5 million rounds of golf were recorded between 2020 and 2023. While the same report found that only “8 patients presented with golf-related neurological injuries to our level 1 trauma center during that same time,” even one is too many. Another study, from 2024 and available to view on PubMed, is titled, and concluded, Golf cart injuries have similar severity to all-terrain vehicle injuries in children. U.S. emergency departments treat roughly 30,000 golf-related injuries each year, with the head and neck the most commonly injured regions. A separate study reports that 156,000-plus golf cart injuries were reported between 2007 and 2017, many involving skull fractures and intracranial bleeds. In early May 2026, for example, a Utah CrossFit gym owner suffered a subdural hematoma and was placed in a medically induced coma after the golf cart she was riding in tipped over. (This accident is now driving a $500,000 GoFundMe, as the woman will face a long road of neurorehabilitation.)

Hidden Price of a Cruise: Hantavirus’ Effect on the Brain

A cruise though the South Atlantic sounds like a dream vacation, but for eighteen Americans, the trip ended as a nightmare. After MV Hondius returned to the United States on May 11, two passengers were placed in biocontainment units because they had developed Andes virus, a strain of the hantavirus. The World Health Organization confirmed this, with eight cases and three deaths reported as of May 8.

In relation to the neurological effects of the virus, hantavirus pulmonary syndrome invades the brain indirectly. Drawing on cases traceable to the 1993 American Southwest outbreak and documented in NLM PubMed literature as far back as 1998, the Journal of the International Neuropsychological Society found that hantavirus pulmonary syndrome survivors exhibited cognitive impairments immediately after acute hospitalization and again at a one-year follow-up, with memory deficits resembling those seen in patients who have suffered brain anoxia, starving the brain of oxygen in a way that mirrors traumatic anoxic injury. Some research also suggests the virus may damage the blood-brain barrier, producing CNS symptoms including headache, insomnia, and vertigo, though this remains incompletely understood. Lasting effects include fatigue, memory loss, and attentional deficits.

Treatment mirrors the approach taken with other forms of acquired brain injury: supportive intensive care, cognitive rehabilitation, and neuropsychological monitoring. A 2024 multicenter cohort study of Andes virus survivors in Chile found that 61.9% reported incomplete recovery at three to six months post-onset, with clustering of both physical and neuropsychological symptoms across patient groups regardless of whether they required extracorporeal membrane oxygenation.

Responding to the 2026 cruise ship outbreak, Admiral Brian Christine, the Department of Health and Human Services’ assistant secretary for health, told reporters, “Let me be crystal clear: the risk of hantavirus to the general public remains very, very low. The Andes variant of this virus does not spread easily.” While the virus can be spread from person-to-person, Andes virus spreads primarily through contact with the urine, saliva, or droppings of infected rodents. Unfortunately, there is currently no approved vaccine for hantavirus pulmonary syndrome in the United States.

Brain Injury Community in Crosshairs of Bipartisan “Claim Sharks” Bill

“We will be suspending your Social Security number because we found some suspicious activities on your Social Security. If you want more information about this case, press 1. Thank you.”

While the above “Robocall Scam Example”, listed on the Federal Trade Commission’s Consumer Advice webpage, may seem to be an obvious scam when viewed in print, the same may not be said when abruptly faced with the concern – particularly if you already have cognitive disabilities. In response to this reality, a new bipartisan bill targets predatory for-profit companies that use robocall software to harvest veterans’ disability data from federal phone lines Advocates state this practice poses a particular threat to veterans living with traumatic brain injury.

Introduced on March 26, 2026, by Rep. Chris Pappas (NH), the Veterans Benefits Information Protection Act, H.R. 8120, was prompted by a 2025 NPR investigation: Florida-based Trajector Medical “CallBot” auto-dialer program placed tens of thousands of monthly calls to a VA hotline, inputting veterans’ Social Security numbers and birthdays to detect disability rating increases and trigger automated billing both with and without veterans’ knowledge.

In addition to Pappas, H.R.8120 counts a bipartisan list of co-sponsors, including Rep. Don Bacon (NE), a retired Air Force brigadier general and co-chair of the Congressional Brain Injury Task Force.  “Our veterans should never be targeted by bad actors trying to profit off their hard-earned benefits,” says Bacon, adding that the bill, which was referred to the House Committee on Energy and Commerce on March 26,2026, “takes a commonsense approach to crack down on predatory practices and protect veterans from exploitation.”

* Scamming, of course, does not solely refer to robocalls. In recent years, the government has given more attention to cyber scams, and particularly as it relates to the disabled. In 2024, the Journal of International Medical Research addressed cyber scams and acquired brain injury, available to PubMed, noting that, “People with acquired brain injury may be more susceptible to scams owing to postinjury cognitive and psychosocial consequences.”)

Pregnant Brain’s Resilience Comes With Risk

As any person who has given birth will confirm, pregnancy transforms nearly every system in the body. The brain is no exception to this change. Much of this neurological alteration is remarkably positive, but, as with other major body occurrences, some of it is genuinely alarming.

Estrogen and progesterone, which surges throughout pregnancy, are now being studied as neuroprotective and neuroregenerative agents in strokes and other brain injuries. Research shows these hormones can reduce the injury cascade by enhancing antioxidant mechanisms, reduce excitotoxicity, and stimulate remyelination. As researchers put it: “Estrogen seems more effective as a prophylactic treatment in females at risk for ischemic brain injury, whereas progesterone appears more helpful in post-injury treatment of both male and female subjects with acute traumatic brain damage.” Additionally, the 2022 Rotterdam Study, available on PubMed, examined 2,835 women over decades, finding that pregnancy and childbirth are associated with a robustly larger global gray matter volume that persists for decades.

The story, though, isn’t all rosy. More recently, contradictory study results have been found. 2025 MRI research published in the International Journal of Molecular Sciences, found on PubMed, showed that pregnancy reduces total cortical gray matter volume by an average of 3%, with losses concentrated in regions linked to social cognition and self-awareness. More acutely, an estimated 7.7 – 15% of all maternal deaths worldwide are caused by stroke, and 30 – 50% of surviving women are left with persistent neurological deficits. “Female stroke survivors were more than twice as likely as their stroke-free counterparts to have another stroke while pregnant and in the six weeks after childbirth,” reported the 2026 American Stroke Association International Stroke Conference.

Ultimately, the pregnant brain endures, often emerging stronger. But, as with every activity that has a significant effect on the body’s function, proper monitoring is required, with even more caution needed for those with a history of brain injury.

Tiny “Brain” Yields Big Answers About Concussions

What if a pea-sized cluster of lab-grown cells could unlock the mysteries of brain injury? Researchers at the University of Cincinnati’s College of Engineering and Applied Science have been doing just that:

Reported by UC on April 21, 2026, UC Assistant Professor Volha “Olga” Liaudanskaya has engineered a tiny, functioning replica of human brain tissue that researchers can safely study. Termed a “mini-brain”, these lab-grown models combine three types of brain cells with two vascular cell types. This, then, creates a complex five-cell system she can observe in living tissue. Simulating concussions and mild traumatic brain injuries on this model, UC engineers can uncover how blunt-force impacts trigger cellular chain reactions that may ultimately lead to long-term neurodegenerative diseases. (Prior models lacked the vascular components, which researchers now recognize as key, driving brain inflammation and degeneration, perhaps reshaping how America protects its athletes, veterans, and kids.)

According to 2026 estimates by the Centers for Disease Control and Prevention, children alone sustain nearly 4 million concussions every year, so the results of this “mini” innovation may be enormous.

Kansas Official Honored for Championing Brain Injury Survivors

On April 17, 2026, Kansas Secretary of the Department for Aging and Disability Services Laura Howard was named the 2026 Brain Injury Champion for her work that has helped thousands of families in the State navigate life after a brain injury. Howard was recognized at the Brain Injury Association of Kansas & Greater Kansas City Annual Professional Conference in Topeka, a distinction that places her at the center of one of the most important disability policy conversations in the State.

As a gubernatorially-appointed cabinet secretary, Howard oversees Kansas’s Medicaid Brain Injury Waiver, a program that funds rehabilitation support for brain injury survivors. Under her leadership, the waiver was expanded to cover a broader range of injuries and now includes children under 16, nearly doubling the number of people it helps. Even Kansas Governor Laura Kelly took notice, publicly praising Howard’s “commitment to supporting Kansans with brain injuries and improving access to care.”

When the Floor Hits Back: Brain Injury in Basketball

Spurs player making a layup shot over a Portland Trail Blazers defender in a crowded basketball arena

San Antonio Spurs star Victor Wembanyama tumbled face-first on the court in the second quarter of Game 2, on Tuesday, April 21, at the NBA Playoffs against Portland. The accident was both a serious blow to the player and the team, as Wembanyama averages 25.0 points, 11.5 rebounds, and 3.1 blocks per game. Fortunately, he returned for Game 4 of the game series, which San Antonio ultimately won. However, it is a sobering reminder both that nobody is concussion-proof and of the immense importance of NBA’s Concussion Protocol.

Through the years, incidents like Wembanyama’s head trauma have become more common and with greater consequences, as today’s NBA players are stronger and more athletic than those from the past. Due to this situation, the NBA finally had the wherewithal to institute a Concussion Protocol in the 2011–12 season. Before it, reportedly just 5.7 concussions were recorded per season in the League. Afterward, that number nearly tripled, not because the game suddenly got much more dangerous, but because of more “accurate reporting secondary to advances in player education, medical knowledge, national media coverage, and standardized testing protocols,” states a 2019 study, Concussions in the National Basketball Association: An Analysis from 1999-2018, available on PubMed.gov.

“A player diagnosed with a concussion should be regularly monitored for 24 hours … the player may not begin the return-to-participation exertion process until 24 hours after the time of injury,” read the original Protocol. In 2026, the Protocol is more rigorous: a player cannot return to full participation for at least 48 hours and must successfully complete cognitive tests before clearance.

High school basketball players in action with one driving past defender near the basket

Beyond the pros, college players are at risk, as are basketball players still in high school and younger. In the 2023 – 2024 season, approximately 250,000 students sustained concussions across nine high school sports, according to the National Federation of State High School Associations. Accordingly, Senator Dick Durbin (IL) introduced Protecting Student Athletes from Concussions Act on September 18, 2025. At that time, S.2889 was read twice and referred to the Committee on Health, Education, Labor, and Pensions. On February 17, 2026, Protecting Student Athletes from Concussions Act was introduced to the House by Representative Mark DeSaulnier (CA). H.R.7590 was then referred to the House Committee on Education and Workforce. No action has been taken on either bill since their introductions. (While no federal sports concussion law yet exists, all 50 states have adopted youth sports concussion laws.)

Although injuries do happen, most notably in the NBA, ultimately a player is responsible for their own safety. In August 2024, the government published a systematic review, Sure Steps: Key Strategies for Protecting Basketball Players from Injuries, available on PubMed. Five of the six strategies highlight neuromuscular training, which includes strength work, stabilization or core, mobility, and agility.
