While cooling is effective for newborns with brain injuries, trials in adults haven't shown the same benefit. However, preventing hyperthermia (fever) is crucial. A fever increases the brain's metabolic demand when its energy supply is already compromised, worsening the injury.
While preserved brains feel like a pork roast, a living brain is much softer, like "tough jelly." A neuroanatomist can easily poke a finger into it. This visceral description highlights the profound physical fragility of our most critical organ and the importance of protecting it.
The core scientific challenge in cryopreservation isn't achieving low temperatures, but avoiding the formation of ice. When water freezes, it expands and shatters cells. The goal is vitrification: cooling tissue so rapidly that it turns into a stable, glass-like state without forming destructive ice crystals.
In epilepsy treatment, patients often use the ketogenic diet for only 2-5 years. The fact that seizures frequently do not return after stopping the diet suggests it can induce lasting metabolic repairs and heal brain dysfunction, rather than just managing symptoms temporarily.
Cytokines, the molecules of inflammation, are essentially distress signals from cells that are struggling energetically. For example, the cytokine IL-6 released after intense exercise is the muscle's way of signaling it needs energy mobilized from other parts of the body.
Hyperbaric oxygen therapy (HBOT) treats CTE by increasing atmospheric pressure, simulating being underwater. This allows blood to behave like a gas, enabling oxygen to bypass blockages and reduce inflammation in the brain. This same effect is achieved through deep-sea diving, which is used as a treatment in Europe.
Dr. Will Bolsiewicz distinguishes between life-saving acute inflammation (fighting infection, healing injury) and detrimental chronic low-grade inflammation. The latter is a constant, damaging immune response likened to a “forever war” inside the body, which is at the root of many modern diseases.
The modern definition of sepsis is not "blood poisoning" but a dysregulated host response. The immune system's inflammatory reaction spirals out of control, causing organ damage long after the initial infection is gone. In fact, fewer than half of sepsis patients have a detectable infection in their bloodstream.
For those without sauna access, a hot bath can be an effective substitute. Studies show a 20-minute immersion from the shoulders down in 104°F (40°C) water robustly activates heat shock proteins and Brain-Derived Neurotrophic Factor (BDNF), mimicking the physiological benefits of sauna use for brain health and muscle preservation.
There is a stark contrast in sports medicine between treating physical injuries and brain injuries. While a muscle strain has a defined recovery plan like ice and compression, a concussion often receives minimal intervention beyond rest. This leaves brain inflammation untreated, potentially leading to long-term conditions like CTE.
Severe trauma in early life can cause a lasting physiological change. It can trigger the immune system to remain in a heightened state, permanently raising baseline inflammation levels and increasing the risk for numerous brain diseases later in life.
