Part 22
Mind, Body, and the Experimental Shelf

Picture a menu that begins with massage and ends with gene therapy. In the same building, sometimes in the same afternoon, you can now have acupuncture, a ketamine infusion, a session of magnetic brain stimulation, a sound bath, and a consultation about injecting immune cells grown in a laboratory abroad. Some of these are old and gentle. Some are approved medicine being stretched beyond its evidence. Some are experiments with a price tag. They do not belong on the same shelf, and this part sorts them.
Clinical scenes in this edition are explicitly labeled illustrations. They describe imagined situations used to explain medical decisions, not documented patients, diagnoses, conversations, or treatment outcomes. They should not be read as evidence that a particular intervention works. Personal recollections are recollections, not medical records.
Evidence grade (draft mapping). 23 questions; a question with mixed evidence counts under each grade.
Treatments for the mind
- 326. Does neurofeedback work?Not convincingly. When the people rating the results do not know who received the real treatment, most of the benefit disappears.Grade pending
- 327. What is TMS, and should healthy people have it for “mental wellness”?Transcranial magnetic stimulation is a proven treatment for depression that has not responded to medication. It is not proven for general wellness.FNot demonstrated / insufficientARobust human trials
- 328. Are ketamine clinics safe?Ketamine can lift severe depression within hours, and for some people it is lifesaving. It belongs in a medical setting with monitoring, not in the mail.ARobust human trials
- 329. What about a nerve block for trauma, and home brain-stimulation headsets?Both have one good trial behind them for a specific condition. Neither is for general use.BLimited or small human studies
- 330. Are psychedelic therapies available?Not yet as approved medicine in the United States, though psilocybin is close.Grade pending
- 331. Do “smart drugs” like modafinil help a healthy brain?Modafinil keeps a tired person awake. It does not make a rested person smarter, and it does not replace sleep.BLimited or small human studies
- 332. Are there memory supplements you consider reasonable to try?A few have small human studies, but none of these products is established dementia prevention. Low risk is not the same as no risk.BLimited or small human studies
- 333. Brain-entrainment headsets, binaural beats, and sound baths?Relaxing for many people. The claims about retraining brain waves are not established.BLimited or small human studies
- 334. Does breathwork do anything measurable?A brief, comfortable slow-breathing practice can improve mood and reduce arousal. The method matters; intense hyperventilation is a different intervention.BLimited or small human studies
Hands-on and traditional therapies
- 335. Does acupuncture work?For chronic pain, modestly, and safely. Part of the benefit comes from the needles and a larger part from the experience of being treated.Grade pending
- 336. Is chiropractic care safe and effective?For low back pain, spinal manipulation gives modest relief comparable to other standard treatments. I advise against forceful manipulation of the neck.Grade pending
- 337. Massage, cupping, dry needling, and assisted stretching?Pleasant, low risk, and helpful for short-term muscle pain and stress. None affects longevity.BLimited or small human studies
- 338. Salt rooms, colonics, and “detox” foot baths?No, no, and no.FNot demonstrated / insufficient
- 339. Do yoga, tai chi, and Pilates count as longevity exercise?Yes, especially tai chi for balance. They complement strength and cardio; they do not replace them.ARobust human trials
Fitness technology
- 340. Can a special bike make me fit in a few minutes a week?In selected participants, very short sprint protocols improve fitness. It is a supplement to regular activity, not a replacement.BLimited or small human studies
- 341. Adaptive resistance machines, bone-loading studios, and weighted vests?The principle of loading muscle and bone is sound. The specific products have little or no trial evidence of their own.BLimited or small human studies
- 342. Exercise with extra oxygen?No clear benefit. Breathing concentrated oxygen while exercising raises power briefly but has not been shown to improve fitness or health.FNot demonstrated / insufficient
The experimental shelf
- 343. What are NK cell infusions and follistatin gene therapy?Experiments sold as products, mostly outside the United States.BLimited or small human studies
- 344. Clinics offer “senolytic protocols” and mail-order rapamycin. Should I?Not outside a study, for the reasons in Part 18. The largest human trials so far missed their main goals.BLimited or small human studies
- 345. Low-dose naltrexone, thymus regeneration, NAD patches, and clinic “stacks”?Each has a small study or a mouse study behind it, and none has shown a benefit for healthy aging.BLimited or small human studies
- 346. Are personalized nutrition programs and DNA diets worth it?Coaching helps. The personalization itself has not been shown to matter much, and diets matched to your DNA do not work better than diets that are not.Grade pending
- 347. Ketone drinks?They raise blood ketones within minutes. Evidence that this improves performance, thinking, or longevity is inconsistent.BLimited or small human studies
- 348. What is the scorecard for this part and the last?Here it is.JClinical judgment / author synthesis
