All protocols

Recommended when concussion is severe; MRI usually does not show molecular abnormalities of concussion but can show contusion or bruising.

Use sophisticated neurologic testing after concussion; eye tracking is described as a very sensitive way to detect brain problems after concussion because tracking worsens. In sports such as football and hockey, pre-season eye tracking can establish a baseline for later comparison.

During concussion recovery, avoid overstressing the brain, but also avoid prolonged sensory deprivation such as staying home in the dark with sunglasses on for long periods. Keep giving the brain input without overloading it.

Mentioned as part of the general vascular-protective approach.

After traumatic brain injury or brain contusion, avoid aspirin because its blood-thinning effects could worsen the injury or cause hemorrhage.

If exploratory or total-body scans reveal findings that concern you, discuss them with a specialist before acting.

For a tiny incidental aneurysm such as a 1.75 mm blister, recommendation was not to change lifestyle; instead, forget about it and get follow-up imaging, as it may never matter clinically.

Guest says he cut back on coffee/caffeine after overdoing work, travel, exercise, and fainting.

Guest says he no longer pushes himself to exercise hard if he is feeling fatigued.

If you feel faint, correlate symptoms with vital signs by measuring blood pressure.

Guest says he personally would not let his kids play football or rugby because of concussion and CTE risk despite acknowledging benefits of team sports.

If you are not a professional athlete, guest suggests choosing other sports with similar benefits and less controversy or risk than football or boxing.

For a common mild head hit or mild concussion causing brief dizziness, guest says in general not to worry or get a scan if symptoms resolve within a relatively short period, such as a day or two.

After stroke, continue moving the body. Evidence supports activity, walking, exercise, resistance training, skill-related training, physical therapy, and even forced activity as beneficial.

Restrain the good limb to force use of the affected limb after stroke; guest notes intriguing data and says it has been shown in animal and some clinical studies.

Guest cautions that forcing use of the affected limb too soon after stroke may be detrimental; timing matters.

Guest describes mild hypothermia as reducing brain/body temperature from 37°C to about 33°C and says he still lets patients cool a few degrees because of possible neuroprotective benefit, while cautioning against excessive cooling.

Do not cool too much after head injury/TIA context; excessive cooling can interfere with metabolic functions and clotting parameters and increase infection risk if temperature goes too low for too long. Guest explicitly would not recommend sticking your head in a snowbank.

Avoid unproven stem cell clinics or traveling abroad for stem cell therapy after stroke or head injury. Guest warns you may not know what you are getting and cites risks including tumors, blindness, and other harms; be careful about therapies that are not proven.

If eating diets without protein, include highly digestible dietary fiber; discussed as enabling gut microorganisms to synthesize essential amino acids.

Use the traditional 'Three Sisters' combination of corn, beans, and squash/pumpkin to complement nutrients in plant-based eating.

Arrange meals to combine complementary foods, such as a carbohydrate source like rice, beans for plant protein, vegetables like lettuce, and for omnivores meat or other protein sources.

Use guayusa as a caffeinated beverage; it has almost as much caffeine as coffee plus antioxidants and other compounds, is described as giving a smooth experience, is traditionally consumed in the morning around 4–6 a.m., can be prepared by boiling and repeatedly adding water, and can be re-steeped for many hours.

Consume chonta, a palm date rich in lipids and fibers, as part of the morning routine.

Use dietary lipids/fats to suppress appetite or extend satiety; described as 'fat fasting' and illustrated by consuming a lipid-rich food after hydration and caffeine.

If you feel like you need a bathroom break to urinate, don't hold it too long because it may be harmful.

Begin higher-protein habits during perimenopause to set up a healthier postmenopause.

Ask your mother and aunts when they went through menopause and whether any medical conditions were associated with it, since genetics is the biggest factor in timing.

Presented as a gold-standard way to assess visceral fat and body composition, though noted as expensive.

Electrical impedance body scanner used to assess visceral fat and muscle mass; described as 'pretty good.'
