The Head-Hands-Heart dementia program provides person-centered care in a way that prioritizes quality of life in persons who have dementia. This article describes how student and community volunteers can be valuable partners in the Head-Hands-Heart program. Nursing homes often struggle with staff shortages, however, including students and community volunteers is a way that facilities can implement the innovative Head-Hands-Heart program while minimizing staff burden. Residents benefit from having consistent social engagement and interaction. Students and volunteers benefit by learning to view persons with dementia as more than their diagnosis. Students and volunteers also learn how to best communicate and interact with individuals to promote and improve residents’ overall well-being.
Migraine is increasingly understood as a disorder of neuronal excitability in which ion-channel function, energy metabolism, and maintenance of transmembrane ionic gradients play central roles. Spreading depolarization (SD) is characterized by a profound redistribution of sodium (Na⁺), potassium (K⁺), calcium (Ca²⁺), chloride (Cl⁻), and water (H2O) between extracellular and intracellular compartments. During SD, extracellular Na⁺ falls sharply while extracellular K⁺ rises, and neurons and glia undergo near-complete depolarization. Restoring normal membrane potential and ionic gradients requires a substantial increase in Na⁺/K⁺-ATPase activity. The Protocol presented here is a non-pharmacological approach developed around the hypothesis that migraine susceptibility is influenced by homeostatic dysregulation of ionic balance, particularly sodium availability relative to neuronal demand. The protocol includes a fixed sodium intake with scheduled fluid consumption, equal sodium and potassium in meals, reduced or eliminated carbohydrates, and selected supplements. An acute “salt test” is used at the appearance of a prodrome or aura to determine whether sodium administration helps with symptom reduction. While the Protocol has helped thousands of migraine sufferers to reduce or eliminate their migraine episodes, this editorial does not present these practices as established clinical treatment. Instead, it evaluates the physiological hypothesis that increasing systemic sodium availability early in a migraine can alter the ionic environment enough to restore membrane gradients, support Na+/K+-ATPase-dependent recovery, modulate the threshold for cortical tissue recruitment into SD, or disrupt SD propagation. This hypothesis remains untested by controlled scientific experiment but is sufficiently grounded in established neurophysiology to generate interesting experimental questions.
Post-traumatic stress disorder and chronic digital exposure are clinically distinct conditions, but the peer-reviewed literature increasingly suggests they engage overlapping biological systems under different exposure patterns. This scoping review maps shared neurobiological pathways across five domains: salience and threat detection, dopaminergic reinforcement, autonomic and hypothalamic-pituitary-adrenal regulation, sleep, and inflammatory signaling. PubMed was searched per a structured Boolean strategy, with 44 studies charted spanning primary studies, systematic reviews, and meta-analyses and reporting per the PRISMA extension for Scoping Reviews. The included evidence supports consistent overlap in amygdala reactivity, dopaminergic reward circuitry, and sympathetic activation. Post-traumatic stress disorder reflects internal persistence after trauma; chronic digital exposure reflects continuous external stimulation that does not stop. Both produce sleep disruption and downstream inflammatory signaling, including elevation of interleukin-6 and other pro-inflammatory cytokines. Beyond shared biology, the review takes up two related working constructs: digital toxicity, used as an umbrella term for the strain produced by chronic algorithmically curated engagement, and memetic disease, describing symptoms that propagate through digital media in patterns documented through mass psychogenic illness and suicide contagion. Both are proposed as working categories rather than established diagnostic constructs, with a four-feature operational framework offered to distinguish memetic disease from neighboring constructs. Longitudinal data and human molecular-level evidence on chronic digital exposure are sparse. The convergence has two practical implications: chronic externally maintained activation deserves the therapeutic seriousness given to acute internal activation, and chronic digital exposure is structurally modifiable in ways post-traumatic stress disorder is not.
Nattokinase (NK) is an orally administered subtilisin-family serine protease with reported activity across multiple proteolytic and cardiovascular targets, including SARS-CoV-2 spike protein, fibrinaloid amyloid microclots, fibrin clots, classical amyloid substrates, coagulation pathways, blood pressure, and carotid atherosclerotic plaque. Spike protein can persist in human tissues and circulation after infection and mRNA vaccination and has amyloidogenic properties capable of converting fibrinogen into fibrinolysis-resistant amyloid microclots. Human pharmacokinetic data demonstrate systemic exposure after oral NK dosing, with peak serum immunoreactivity at approximately 13 hours. Three independent laboratories have reported proteolytic degradation of spike by natto-derived or related alkaline serine proteases. Whole natto extract degraded recombinant receptor-binding domain and abolished viral infectivity in cultured cells; purified NK degraded full-length spike, the S2 subunit, and cell-surface spike in a dose- and time-dependent manner; and an unrelated alkaline serine protease independently reproduced spike degradation. Recombinant NK also degrades fibrinaloid microclots in vitro, while classical amyloid substrates susceptible to NK include Aβ40, Aβ42, human prion peptide fibrils, insulin fibrils, and β2-microglobulin fibrils. Fibrinolysis remains NK’s best-established biological activity. NK directly cleaves fibrin independently of plasminogen, inactivates plasminogen activator inhibitor-1, promotes tissue plasminogen activator release, and inhibits platelet aggregation and thrombus formation. Oral administration produces measurable systemic pharmacodynamic effects in humans, including changes in D-dimer, fibrin degradation products, factor VIII, antithrombin, activated partial thromboplastin time, fibrinogen, factor VII, and von Willebrand factor. Randomized evidence also supports modest blood-pressure reduction. Carotid imaging studies show no significant plaque effect at 2,000 or 3,600 FU/day, whereas 6,000 and 10,800 FU/day were associated with approximately 36% plaque reduction, suggesting a possible threshold near 6,000 FU/day. Higher natto intake is also associated with lower cardiovascular and stroke mortality. Overall, NK is a multi-target proteolytic agent with established fibrinolytic activity and convergent preclinical evidence against spike and amyloid substrates. The principal unresolved question is whether orally administered NK reaches these targets at catalytically sufficient concentrations in humans to produce measurable clinical benefit.
Every speaker hears a mix of two versions of their own voice: the airborne signal that others hear, and a bone-conducted "private channel" carried by vibration from the vocal tract and skull to the cochlea. This channel does not appear in recordings, and is the one most likely to change as a child's skull grows. Bone conduction is used clinically to separate conductive from sensorineural hearing loss. This paper asks whether it also matters for neural, language and sensory development. This narrative synthesis joins two bodies of evidence that are rarely read together: recent acoustic-engineering work (largely 2021–2026) that treats the head as a coupled mechanical, fluid and acoustic system, and clinical literature on craniofacial anomalies, otologic disease burden and skull growth in autism spectrum disorder (ASD). It aims to separate established physiology from hypothesis. Classic bone-conduction mechanisms now include cerebrospinal-fluid pressure transmission. Modeling and cadaveric studies show that transmission depends on stimulation site, frequency, coupling and individual anatomy, and that soft tissue and the air-filled paranasal and mastoid cavities shape the conducted signal. Children with ASD show elevated rates of minor craniofacial anomalies, atypical head-circumference trajectories, otitis media and sinonasal disease. Early conductive hearing loss can affect speech-in-noise perception, and skull morphology alters the intelligibility of bone-conducted speech in adults. Regional skull-acoustic phenotyping has been performed in children with specific language disorders, and offers a transferable protocol. Two trajectories are proposed by which skull morphology could influence speech: one through middle-ear disease and fluctuating hearing, the other through direct effects on articulation. No study has yet measured a bone-conduction transfer function or regional skull-acoustic phenotype in ASD or auditory processing disorder and linked it to outcomes, so the proposed chain from skull growth to altered self-heard voice to neural and language development remains unproven. Interventions are tiered. Routine otolaryngological and audiological screening and treatment of adenoid, sinus and middle-ear disease are justified now. Direct transfer-function measurement in children, replication of the phenotyping protocol and adapted bone-conduction devices depend on confirmation, and on standardized measurement methods. The hypothesis is offered as a starting point for research.
