Spring Forward, Fall Down: Neurological Effect of Time Change

Every March, we lose an hour of sleep, or we gain an hour of sunlight, depending on your perspective. For TBI survivors, this forced clock shift has medically been proven to be particularly cruel. Up to 70% of survivors already struggle with disrupted sleep and circadian rhythms. Unfortunately, that is the same biological clock that drives the neural repair process itself.

The twist, though, is that the extra daylight we are about to gain can actually help injured brains heal. Powered by sunlight, studies have shown that Vitamin D is typically low in brain injury patients, particularly at rehab admission, and deficiency is linked to worse survival. While adding a Vitamin D supplement into your daily pill regiment is good, natural Vitamin D absorption is always best.   

While it may seem a biannual norm, it wasn’t until March 19, 1918 that time became a legislative concern in the United States. President Woodrow Wilson signed the Standard Time Act of 1918, also known as the Calder Act, “to save daylight and to provide standard time, for the United States.”. (On January 20, 1942, President Roosevelt established War Time, which halted the time shift from 1942 – 1945.)

More recently, opposition to time change has increased and a vast minority of Americans say that they do not want to keep switching their clocks. In Congress, S.29, Sunshine Protection Act of 2025, sponsored by current Secretary of State, former Florida Senator, Marco Rubio and Rep. Vern Buchanan (FL) would have made Daylight Savings Time permanent. This Congressional year, Rep. Greg Steube (FL) introduced H.R. 7378, Daylight Act of 2026, that would permanently move U.S. clocks forward by 30 minutes and eliminate the biannual time change. As of March 4, 2026, this Act is in the House.

*British Columbia will permanently adopt year-round daylight saving time in 2026, with the final “spring forward” occurring on Sunday, March 8, 2026. It may be useful to observe how this change, or lack there of, functions in another country that has same time zones before passing legislation.

“Eat Your Vegetables” for a Healthy Brain

Vitamin K is generally known for its role in blood clotting, but scientists have long been uncovering its powerful impact on brain health. Available to view through PubMed, biochemical journal Biofactors noted as far back as 2012, “There is now convincing evidence that vitamin K has important actions in the nervous system.” A 2022 study published in Nature, also available on PubMed, found that vitamin K suppresses ferroptosis, a type of cell death driven by lipid damage and linked to brain injury. 

Vitamin K activates brain proteins Gas6 and protein S, which shield neurons from damage and support cell recovery after injury. While the vitamin is important for all people’s brain health, it is life-or-death for infants. The CDC has reported that babies who don’t receive a vitamin K shot at birth are 81 times more likely to develop Vitamin K Deficiency Bleeding [VKDB]. Between 30% and 60% of late-onset cases of VKDB involve brain hemorrhage, and one in five affected infants will die.

More recently, the public medical library published a 2025 Tufts University study, first reported in The Journal of Nutrition, that confirmed “low vitamin K intake reduced menaquinone-4 concentrations in brain tissues and impaired learning- and memory-related cognitive function.” 

Beyond neuroprotection, the NIH Office of Dietary Supplements notes that Vitamin K strengthens bones and supports healthy blood circulation. The old adage of “eat your vegetables” is apropos, as top food sources include kale, spinach, broccoli, and Brussels sprouts.    

Developing the “Dancing Molecule”

Northwestern University scientists have developed an injectable nanomaterial, dubbed “dancing molecules”, that cross the blood-brain barrier and shield brain tissue from post-stroke damage. Published January 2026 in Neurotherapeutics, the therapy uses tiny, constantly moving molecular assemblies, known as supramolecular therapeutic peptides (STPs), delivered intravenously that self-organize into nanofibers inside injured brain tissue. In mice, a single IV dose given after blood flow was restored significantly reduced inflammation, tissue death, and harmful immune response with no observed toxicity.

In July 2025, Amphix Bio, the company behind the treatment, posted on LinkedIn: “We are thrilled to announce the FDA has granted an Orphan Drug Designation to AMFX-200, our lead candidate based on the Supramolecular Therapeutic Peptide (STP) platform, for the treatment of acute spinal cord injury. This will accelerate our efforts to bring this novel neuro-regenerative therapeutic to the clinic.”*

* I cannot find any record of human trials of this stroke treatment, as of yet. Additionally, key limitations remain, as results are preclinical only, dosing must be precise to prevent blood clotting, and long-term human safety is unproven.

Liquid Gold for Your Brain: Extra Virgin Olive Oil

Your pantry might hold one of the most powerful brain-protective foods on the planet. Research now links extra virgin olive oil (EVOO), long recognized as a boon to heart health, to a sharply lower risk of dementia, faster brain injury recovery, and protection against the toxic plaques that drive Alzheimer’s disease.

The National Institute on Aging states, “Consuming olive oil is associated with lowering the risk of dementia-related death.” This association was found to be true “regardless of overall diet quality”. These findings were compelling enough that the 2025–2030 U.S. Dietary Guidelines, issued by USDA and HHS, placed olive oil at the center of the new federal nutrition framework.

The 2026 PREDIMED-Plus study, which focused on the benefits of the Mediterranean diet for reducing the risk of type 2 diabetes, revealed that EVOO works through the gut-brain axis, with participants showing improved memory and cognitive function alongside greater microbiota diversity. Animal studies from 2025 showed that oleocanthal, a polyphenol unique to high-quality EVOO, reduced brain infarct size and sped recovery after traumatic brain injury.

The key is EVOO’s polyphenols, specifically oleocanthal, oleuropein, and hydroxytyrosol, which cross the blood-brain barrier, clear amyloid plaques, and calm neuroinflammation. Only cold-pressed extra virgin oil retains these compounds at therapeutic levels, so quality matters. Refined olive oil could not replicate these results.

Ready to cook for your brain? Try combining EVOO with other ingredients known to promote brain health, such as salmon, or another staple of the Mediterranean diet, mint.

Pentagon’s New Coding Rules Aim to Protect Warfighters

On January 23, 2026, the Department of Defense’s Traumatic Brain Injury Center of Excellence published updated ICD-10-CM coding guidance specifically for warfighter brain injuries. ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) is the standardized system doctors use to classify and record diagnoses. Without precise codes, injuries go miscounted and undertreated.

The new guidance is particularly critical now, as modern warfare inflicts unique brain hazards. Low-level blast overpressure from repeated weapons firing, extreme G-forces on pilots, and unexplained neurological incidents now have dedicated diagnostic codes, enabling better surveillance and resource allocation.

Just days earlier, on January 20, the Center released a research review revealing that mild TBI raises PTSD risk two- to threefold, findings that will shape military treatment protocols. Meanwhile, the Army’s baseline cognitive screening program, launched in August 2024, aims to assess every troop’s brain health proactively.

Minnesota Overhauls Brain Injury Waiver Program

Minnesota’s Brain Injury (BI) Waiver Program has supported survivors of traumatic and acquired brain injuries since 1992. In 2026, it is facing sweeping changes, bringing both new benefits and serious concerns for tens of thousands of residents who depend on it.

On the positive side, the program covers 44 distinct services, has no waitlist, and swim lessons have been added as an allowable Consumer Directed Community Support expense. Administratively, “MnCHOICES is a computer application used… to support their assessment and support planning work for Minnesotans who need long-term services and supports (LTSS), regardless of age, type of disability or service needs.” 

But disability advocates are alarmed. The 2025 Legislature passed $1.3 billion in disability waiver cuts, and structured day services – vital therapeutic programming for brain injury survivors – have been removed from the BI Waiver service definition entirely. Currently, roughly 15 to 20 states run standalone brain injury waivers, including Colorado, New York, Massachusetts, and Kansas, though they vary widely.

Additionally, recent investigation into the state’s BI Waiver Program, and into Medicaid grants, as a whole, seems to have also uncovered significant fraud, including overbilling for services, billing for services not rendered, and improper billing by unlicensed staff. In January 2026, this discovery of fraud prompted the state to freeze enrollment of the Brain Injury Waiver Program, and other programs.

Helmet Lab Results Expose Need for New Youth Standards

Brain damage, particularly CTE, has widely been discussed in the past decades as a negative consequence of football. Beyond action on the field, a growing body of research reveals that this damage may be exasperated by the equipment worn by players to prevent harm. Research links heavier football helmets to increased brain injury risk in young players.

Virginia Tech’s Helmet Lab found that children, whose neck muscles are weaker and heads proportionally larger than adults’, are especially vulnerable – sustaining concussions at approximately 60g of head acceleration, compared to roughly 100g for college athletes. This knowledge has resulted in a drive of both equipment reforms and legislative action for youth football across the United States. Led by the National Operating Committee on Standards for Athletic Equipment, new StandardND005 regulations were finalized in July 2025. Youth football helmets must be a maximum of no more than 3.5 pounds, effective September 1, 2027.

States are also not waiting. In West Virginia, Senate Bill 657, the Cohen Craddock Student Athlete Safety Act, named for a 13-year-old who died August 24, 2024, from a football-related brain injury, advanced through the Senate Education Committee on February 12, 2026. The bill would allow schools to adopt protective soft-shell helmet covers during practices. At the federal level, Senator Durbin (IL) introduced S.2889 on September 18, 2025, conditioning federal education funding on state-level concussion safety protocols. (Beyond this initial reading, no further action appears to have been taken.)

Studies Explore Plasma as Key to Human Survival & Recovery

Fresh frozen plasma, the liquid part of blood stripped of red and white cells, may hold the key to saving more lives after traumatic brain injury. The U.S. Department of Defense has been funding research on this for over a decade. While significant studies remain in operation and, therefore, a comprehensive review cannot yet be reported, the results are increasingly hard to ignore.

The most significant step forward is the FIT-BRAIN Trial, a federally funded study that began enrolling patients in early 2024 across eight U.S. trauma centers. Researchers at Northwestern University, backed by the Pentagon’s Congressionally Directed Medical Research Program, are testing whether plasma given soon after a severe brain injury can limit damage and improve survival. (The trial targets 357 patients, with results expected around 2027.)

Other recent studies have already built the case. A January 22, 2025 paper in the Annals of Surgery journal, driven by federally-funded studies, found that patients given cold-stored platelets after brain injury needed emergency skull surgery 14 percent less often and a 2025 analysis of nearly 15,000 children with severe brain injuries found that plasma given within four hours cut early death risk by nearly half.

In Fiscal Year 2025, Congressionally Directed Medical Research Programs funding was cut 57%, to $650 million, with Traumatic Brain Injury and Psychological Health Research Programs receiving zero dollars for new research grants. Recently, FY2025’s financial research crisis was partially resolved. On February 3, 2026, President Trump signed the Consolidated Appropriations Act, 2026 (P.L. 119-75), restoring CDMRP funding to $1.27 billion across 34 research programs.

A Gift from the Heart to the Mind

This Valentine’s Day, that box of dark chocolates may offer more than romance. A body of research indexed in PubMed reveals that dark chocolate’s primary flavanol, epicatechin, is a potent neuroprotective compound with remarkable potential for brain injury recovery.

“Epicatechin represents a promising therapeutic candidate for traumatic brain injury – its multi-pathway neuroprotection, from antioxidant defense to neurogenesis, makes it unlike any single pharmaceutical agent,” stated Wang et al. in 2024 in CNS Neuroscience & Therapeutics. Research shows that administering epicatechin after traumatic brain injury prevents neuronal death, reduced neuroinflammation, and restored neurological function by targeting the AKT-P53/CREB signaling pathway. This pathway then promotes cell growth and inhibits apoptosis. A 2025 meta-analysis in the Journal of Agricultural and Food Chemistry pooled 12 animal studies and confirmed epicatechin significantly improves outcomes across TBI, ischemic stroke, and other brain injury types, while reducing oxidative stress and boosting antioxidant defenses.

Dark chocolate’s brain benefits operate through multiple pathways: boosting cerebral blood flow by 8-10% via nitric oxide–mediated vasodilation, activating the Nrf2 antioxidant system, elevating the brain-derived neurotrophic factor critical for neuronal survival, and stimulating neurogenesis. Crucially, these are the very mechanisms disrupted by traumatic brain injury and stroke.

While most current TBI-specific evidence remains in animal models, the results are compelling. This Valentine’s Day, choose dark chocolate with the highest cocoa content you can find, preferably 70% or above. Your brain, and your loved one’s brain, will thank you.

Federal Research Reveals Complex Relationship Between Antidepressants & Brain Injury

For years, doctors worried that antidepressants might worsen brain bleeding after traumatic brain injury. A 2026 study published in Neurology and cataloged in the U.S. National Library of Medicine challenges that fear. Finnish researchers tracked 54,876 brain injury patients over thirteen years and found something unexpected: those taking antidepressants showed no increased risk of death or emergency surgery. “These findings provide reassurance for people who take antidepressants that antidepressant use does not appear to worsen early recovery after traumatic brain injury,” said lead author Dr. Jussi P. Posti of Turku University Hospital in January 2026.

The picture grows more complex when considering blood clots. Multiple studies indexed by the NLM show a modest statistical link between antidepressants and clotting. Researchers, though, suggest this association may reflect depression itself rather than the medication, since these drugs actually thin the blood.

This distinction matters enormously. According to federally funded research tracked by the National Institutes of Health, over half of brain injury patients develop depression within their first year of recovery, and they face eight times the general population’s depression risk. The CDC explicitly recommends screening and treating this depression because untreated cases impair cognitive recovery and triple non-adherence to rehabilitation.

Most critically, NIH-hosted research shows brain injury survivors face nearly twice the suicide risk of others, with depression as the strongest predictor. The government’s message is clear: not treating depression after brain injury can carry serious, documented dangers.
