Last week, in part 1, I covered Steven Fowkes’ “cures” for Alzheimer’s and herpes. In part 2, I will cover a video where he goes further afield. It is titled “Nutrients for Better Mental Performance,” but he also discusses sleep, depression, hangovers, and a lot of other topics.
Some of what he says are simple truisms: mental performance is affected by everything related to health such as sleep, food, vitamins, minerals, detoxification, nutrients, amino acids, hormone replacement, pharmaceuticals and herbs. Metabolism is the key to brain function: 3% of the body uses 20% of the energy. Macronutrients, micronutrients, exercise, water, and breathing are important too.
We knew that.
Which nutrients promote optimal brain function? All of them: any deficiency will affect the brain. Fowkes goes beyond the evidence to claim that some nutrients are needed at super-physiological levels; Mother Nature is not optimal. Some supplements appear to work but the effects are not sustainable. It’s not about parts, but about how things work together. (more…)
The Accreditation Council for Graduate Medical Education (ACGME) has released proposed new standards to limit working hours for medical residents. Bus drivers are allowed to drive for 10 hours and then are required to have 8 hours off duty. Airline pilots can be scheduled for up to 16 hours on duty — being at work, ready to fly — and up to eight hours of actual flight time in a 24-hour period, with a minimum of eight hours for rest between shifts. Physicians in residency training work 80 hours or more a week (compared to 75 hours a month for airline pilots) and are regularly on duty for more than 24 hours at a time. If adequate rest is an important safety measure for drivers and pilots, isn’t it important for doctors too?
When I was an intern and resident, my hours were a little better than some. Instead of every other night, I was on call every third night. I had to work from about 7 AM one day to 5 PM the following day (34 consecutive hours). I stayed in the hospital: there was a call room with a bed, but if we got to lie down it was never for very long. When I got off duty, my sleep-deprived body demanded that I go home and crash. It was only every third day when I worked “only” a 10 hour shift, that I could devote an evening to all the other activities of my life like laundry, grocery shopping, and trying to read medical journals. One memorable weekend I worked from Saturday morning to Monday evening and only got to lie down for about 20 minutes. I don’t think I made any fatigue-induced mistakes that hurt patients, but by Monday afternoon I was groping my way through brain fog and running on fumes. (more…)
Sleep that knits up the ravelled sleeve of care
The death of each day’s life, sore labour’s bath
Balm of hurt minds, great nature’s second course,
Chief nourisher in life’s feast. -William Shakespeare, Macbeth
The company that makes the Zeo Personal Sleep Coach kindly sent me one of their devices to try out. It’s a nifty little gadget, and if you are a techno geek, you would probably love it. It’s a fascinating toy; but for insomnia, there’s no evidence that it provides any benefit over standard treatment with sleep logs and sleep hygiene advice.
Polysomnography is done overnight in a sleep lab and costs around $1000. It records multiple parameters: EEG, EKG, EMG, breathing, O2, CO2, and limb movements. It is most commonly used to diagnose obstructive sleep apnea (OSA), a serious condition that is linked to hypertension, heart disease, diabetes, metabolic syndrome, stroke, and increased mortality. OSA can be effectively treated with CPAP and other measures. About 50% of snorers have sleep apnea. We typically think of it as a disease of obese, loudly snoring older men, but even young children can have it: snoring is probably never normal in children and should be investigated.
The Zeo is the first sleep monitor available for consumers to use at home. It doesn’t pretend to do what polysomnography does. It can’t diagnose sleep apnea. It is billed as an educational and motivational tool, not intended for the diagnosis or treatment of sleep disorders. A unit that looks sort of like an alarm clock sits on your bedside table and communicates wirelessly with a comfortable soft elastic headband that positions embedded sensors over your forehead to pick up your brain waves.
