SLEEP SCHEDULE AND DEMENTIA RISK

Association of the Sleep Regularity Index With Incident Dementia and Brain Volume | Neurology

While scouring some of the week's most interesting new research digest I came across this great piece in a major neurology journal. It hits a little bit of a raw nerve as 1 of the 2024 new years resolution at our household has been to be more diligent about sleep schedule, both the duration, quality, but also trying to have it as consistent as our life's demands allow. The latter can be a little tricky with puppy schedule, work conferences and other demands that are a bit out of our control.

When considering the 4 pillars of health (nutrition, movement, stress, sleep/rest), it still seems like stress and sleep are considered the "softer variables" of general health, when in reality they need to be taken with the same degree of seriousness. Sleep is 1 of those areas of our life where it's easy to cut corners and think we will not deal with any real consequence. As this article suggests, that may not be the case, with some rather serious chronic stress on the central nervous system that will manifest with a much higher risk of dementia.

Sleep is a complicated topic, and poor sleep can be very difficult to troubleshoot. For starters, however, we can all commit to a routine that involves a consistent bedtime and wake up time most days out of the week, as an easy step in the right direction. ( photo image courtesy of Freepik)

Epilepsy, cervical curvature, cerebral blood flow and chiropractic

While I do not see a lot of patients with epilepsy, they periodically show up in clusters at the office , and as a nerd loving all things scientific I was fascinated by a recent podcast from a colleague who does work a lot with that specific medical population. The connection works as follows: there is increasing well documented medical evidence based on imaging that a predisposition to seizure activity in a part of the brain is a decreased blood flow to the area. The decreased blood flow means less available nutrients that help maintain adequate energy production in neurons, so they will not randomly fire off, meaning that decreased blood flow decreases electrical firing threshold. In turn, we know from much confirmed research that reversed cervical sagittal alignment such as altered lateral cervical curve can be associated with decreased blood flow to the brain. So the final equation is: abnormal cervical sagittal curve alignment equals decreased cerebral blood flow equals potential threshold for seizure. This especially caught my attention as I'm slowly working my way through 1 of my (unfortunately deceased) colleague's book on the impact of upper cervical cranial alignment on cerebral blood flow. Cervical sagittal alignment and postural distortion really is not just about posture and pain, but has widespread ramification on neurology and it turns out, their domino effect of altered cerebral blood flow and vascular input in and out of the cervical spine to the head.

Standing forward : an easy standing version of the child's pose for quick lumbar decompression

For some reason we have been going over this quick lumbar decompression stretch a lot with patients over the last 2 weeks, and Steve and I decided to record a refresher of the technique. It's basically a form of standing child's pose, which can be done at any place and pretty much at any time without the limitations of having to find a comfortable floor to kneel. It's also a good option for patients who have limitation of knee range of motion that do not allow them to get into the kneeling position in the 1st place.

Metabolic sources of pain: MSG

https://pubmed.ncbi.nlm.nih.gov/26900907/

A while back I blogged about the connection between MSG and mysterious episodic headaches. This connection is getting more traction among lay people, although the difficulty still remains in patients correctly identifying MSG under different names in food labeling. While cleaning up my desk at the beginning of the new year, I came across a research article from 2016 that I had carefully kept, about the "pro-algesic" effect of certain foods, meaning the effect of foods on increased pain perception.

In this blog I want to uncover another aspect of MSG that is less well known but nonetheless fairly well documented in the medical literature. The connection between MSG and increased pain sensitivity. In our practice we often see patients with chronic pain. Chronic pain is multifactorial, meaning that it has several contributing factors that compound each other. As such it's important to try to remove as many triggers as possible because of the cumulative effect. Obviously with chiropractic we tend to address quite a bit of the neuromusculoskeletal triggers, and try to point patients in the direction of underlying metabolic and inflammatory triggers over which they can have control. MSG is turning out to be a pretty important player among patients with chronic pain in the "fibromyalgia" family, since MSG increases central nervous system pain transmission and perception, and in that way is different from more peripheral sources of pain sensitization such as chronic systemic inflammation.

As with headaches, patients need to learn to recognize the hidden sources of MSG, which will often steer someone to eat a less processed food diet. It may feel a little bit daunting at 1st but it certainly a worthwhile strategy to pursue, since chronic pain can be so life altering, and this is a relatively easy way to decrease its impact.

Cervical passive lordotic traction device ( the "Wave" ) for restoring normal cervical curve

https://www.youtube.com/watch?v=BibKL5FtPzc

We recorded this video as a brief intro to what the device looks like and its main indications. As in all things real life, the devil is in the details and we use the wave, and don’t use it, for a variety of indications. Its main application is to create passive lordotic distraction force in patients with cervical curve reversal. Younger patients with recent ligamentous injury in flexion/extension are the best candidates. Patients with moderate to advanced degenerative changes may have contraindication to using the device since any extension will aggravate stenosis and neurological compromise from things like bony spurs. Same goes with patients with positionally triggered vertigo. If unsure, ask us if you are a candidate and we will evaluate your individual needs

HORMONE DISRUPTING CHEMICALS IN MENSTRUAL CARE PRODUCTS

Chemicals in menstrual products: A systematic review - Marroquin - BJOG: An International Journal of Obstetrics & Gynaecology - Wiley Online Library


This blog belongs more so to the "PSA" category of information blurbs rather than to the bread-and-butter of what we do every day, but I think it's a significant enough subject affecting half of the world population that it should be out there. I do a fair amount of nutritionally balancing work on women's hormonal concerns, and I do have to admit that this particular source of toxic hormone interference is often a bit too far below my radar although it shouldn't be. (We talked quite a bit about the hormone mimicking chemical exposure in food body care products and plastics, but not so much in "feminine hygiene products").

This particular piece of research highlights the fact that the majority of menstrual products can contain extremely high levels of chemicals that mimic hormones and bind to hormone receptors in a negative way, especially since they are in closer proximity and contact to estrogen sensitive tissues. Over the years I've had several women report some immense relief of chronic menstrual pain and cramping when switching to organic care products, highlighting that this could be a hidden source of dysmenorrhea.

Finding an alternate product is not as daunting as it may sound, there are a lot of organic options to chose from on the open market. The bottom line is to start stocking up on safer pads and tampons.

HOW MANY PLACES CAN THE NECK REFER TO ?

This blog came out of a fun quiz we designed during a recent business open house of a fitness facility to which we were invited. The idea was to engage the visiting public by having them take a quiz to earn ticket raffles for our door prizes. It became clear that this particular quiz question generated a lot of further questions and conversations, so I decided to turn that into an educational blog.

The question was pretty simply put: to how many different places can the neck cause referred symptoms? The answer to the question is for: the head, the arm, (most people got those to right), the upper back, and the chest. The latter 2 were less obvious to some people.

The cervical spine contains a variety of structure from the cervical disc, facet joints, and various muscular structures. Depending upon which structure is affected and at which level of the neck, it will have its own referral pattern, sometimes mixing and matching a variety of destinations. So the cervical spine should always be a place of investigation with ongoing and non-resolving symptoms in those 4 areas.

The long rap sheet and hidden sources of artificial sweeteners

A while back I blogged about MSG as a differential diagnosis to always consider in cases of mysterious headaches, since it can be an unrecognized trigger to episodic headaches, all the more difficult to pinpoint since MSG is frequently listed under different name in food labeling. Today I want to talk about the equivalent for chronic mysterious abdominal pain and bloating episodes: artificial sweeteners, in particular in the sugar alcohol family. They have become excessively common, inserting themselves in a multitude of foods, especially "healthy foods", and unbeknownst to a lot of people, creating havoc on the guts.

Artificial sweeteners come in a variety of forms. None of them good. The list of problems associated with artificial sweeteners and the negative research associated with them only continues to grow, unfortunately not always matched with popular publicity, much less personal practices of cutting them out altogether. If anything, the trend of popular perception goes in the other direction, with patients being increasingly lulled into thinking that those are benign food additives that cause no problem, and if anything help them maintain normal weight.

What prompted this blog entry was two patients back to back dealing with rather profound but episodic abdominal pain bloating and nausea, which had been extensively medically worked up but remained a mystery. In both instances, through a set of accidental circumstances, the culprit was found to be a sugar alcohol that was added to foods without the patient's awareness . In both instances, there was an accidental change of normal dietary pattern leading to the removal of the offending artificial sweetener, then the reintroduction, with matching resolution and recurrence of the symptoms that finally led to the correct problem identification.

Sugar Alcohols are particularly high on my hit list because of their prevalence and the problems that they cause. They are a form of very small carbohydrates that give a sweet taste to our tongue but cannot be used for energy production like regular sugar, and in many cases, cannot be absorbed (with a few notable exceptions like allulose) . A few of them occur in very very small amounts in nature, thus leading to the fallacy that because they are "natural" we can use them in large synthetic amounts. However, the amounts found in actual exposure to things like fruit has a vastly different metabolic effect from the concentrated synthetic variants. Among other things, they cause a significant disruption of our gut microbiome, and tend to ferment in our G.I. causing pain, bloating, flush diarrhea, and essential nutrient malabsorption. In addition, they can be associated with liver dysfunction, metabolic dysfunction, and increasing insulin resistance.

What makes them all the more pernicious is that they are often added to foods that patients perceive as healthy alternatives, such as protein bars, and often in places where you do not suspect them, such as protein powders, gum, powdered beverages, electrolyte powders, etc. Even if the amount in each source may not be all that high, the combination of 2 or 3 sources during the day can be enough to tip someone into full-blown abdominal pain, unexplained.

Some of those sugar alcohols include xylitol, sucralose, erythritol, mannitol, and allulose. Should try to avoid all of them whenever possible, and remember that small amounts of naturally occurring sugar have been around for several millennia and our body is tolerant and adapted to them, while some of these newer synthetic chemicals are not. In this case, there is no shortcut to eating smart and simply healthy. For more information, please refer to this excellent blog entry from the Kresser Institute
