Is The Cure Worse Than The Disease?

Do blood pressure medications cause memory lossHigh blood pressure has been called a silent killer. This is because it is possible to go for years with high blood pressure and not even know it. Even worse, the consequences of untreated high blood pressure can be catastrophic – stroke, heart attack, congestive heart failure, kidney failure – the list goes on and on.  But, what about when high blood pressure is treated?  Do blood pressure medications cause memory loss?

Because of that, the standard medical recommendation for years has been to:

  • Have your blood pressure tested frequently (at least once a year if your blood pressure is in the normal range and more frequently if it is elevated).
  • If your blood pressure is elevated, get on a blood pressure medication and try to keep your blood pressure as close to normal as possible.

But, is this always the best advice? Maybe not, particularly when we consider the confusing effects of blood pressure on cognitive function.

We have known for years that untreated high blood pressure in middle aged individuals significantly increases the probability that they will suffer cognitive decline in their later years (for example, R. F. Gottesman et al, JAMA Neurology, 71: 1218-1227, 2014).

Conversely, when we look at the elderly as a group we find that those with the lowest blood pressure actually have a higher risk of cognitive decline than those with the highest blood pressure (for example, B. Sabayan et al, Journal of the American Geriatric Society, 60: 2014-2019, 2012).

How can we reconcile such conflicting data on the correlation between blood pressure and cognitive decline in the elderly? Could it possibly be that it was the blood pressure drugs rather than blood pressure itself that was causing cognitive decline in the elderly?

Do Blood Pressure Medications Cause Memory Loss?

blood pressure medicationsA group of scientists in Italy set up a clinical study to determine whether blood pressure or use of blood pressure drugs better correlated with cognitive decline in elderly patients who already have some degree of cognitive impairment (E. Mossello et al, JAMA Internal Medicine, doi: 10.1001/jamainternmed.2014.8164).

They enrolled 172 patients from 2 outpatient memory clinics in the study. The average age of the participants was 79 and all of them had some degree of cognitive impairment (68% with dementia and 32% with mild cognitive impairment). 70% of the study participants were on blood pressure drugs. Their blood pressure was measured on a daily basis, and they were tested for cognitive function at the beginning of the study and 9 months later.

The results of the study concerning:

  • Those with the lowest blood pressure had the highest rate of cognitive decline over the 9 month period. These results were similar to several previous clinical trials with the elderly.
  • The association between low blood pressure and cognitive decline was only seen in those subjects on blood pressure medications. Low blood pressure did not increase the risk of cognitive decline in unmedicated subjects.

There are, of course, some significant limitations to this study:

  • It is a small study of short duration.
  • It is the first study of its kind. It needs to be repeated.
  • It was done in an elderly population who already suffered from cognitive decline. We don’t yet know to what extent these conclusions will apply to younger people and to people without cognitive impairment.

Is The Cure Worse Than The Disease?

However, this study does raise a huge red flag that needs to be evaluated very carefully. It raises the issue of whether aggressive drug treatment to bring blood pressure under control may, under some conditions, cause more problems than it cures. It is not unlike the study a few years ago showing that aggressive treatment to lower blood sugar levels in type 2 diabetics actually increased the death rate (C. J. Currie et al, The Lancet, 375: 481-489, 2010).

It turns out that increased risk of cognitive decline is just one of several risks associated with aggressive drug treatment to lower blood pressure. Because of that realization an expert panel recently recommended that the threshold for the use of blood pressure drugs be raised from 130/90 to 140/90 for adults under 60 and to 150/90 for adults over 60.

Do blood pressure medications cause memory loss?  It’s not that high blood pressure has suddenly become healthier. Rather, the experts realized that the risks of aggressive drug treatment to lower moderately elevated blood pressure outweighed the benefits. The cure was worse than the disease!

Is There Another Option?

dash dietThe answer is a resounding yes, and we have known about it for years. It is called the DASH (Dietary Approaches To Stop Hypertension) diet. It is recommended by the American Heart Association, the National Heart, Lung & Blood Institute, the USDA 2010 Dietary Guidelines for Americans and the US Guidelines for Treatment of High Blood Pressure). Coupled with a few simple lifestyle changes it has been shown to be as effective as drugs at reducing high blood pressure, without the side effects of the drugs.

You can find the details of the DASH diet here (http://dashdiet.org/), but in simple terms, it is low in fat, high in fresh fruits and vegetable, fiber and low fat dairy products. The recommended lifestyle changes are weight control, restricted sodium intake and exercise.

Although not all experts agree, I personally recommend that you also make sure that you are getting the DV for calcium, magnesium and vitamin D from food and supplements and consider supplementing with long chain omega-3 fatty acids and polyphenols – especially resveratrol and related polyphenols from grape skins and seeds.

 

The Bottom Line

  • High blood pressure is a silent killer because people often don’t know they have it. If left untreated it can cause stroke, heart attack, congestive heart failure and kidney failure.
  • However, a recent study suggested that aggressive drug treatment to treat high blood pressure in the elderly can increase the rate of cognitive decline.
  • Because of this and other risks associated with aggressive drug treatment for high blood pressure, especially in the elderly, an expert panel recently recommended that the threshold for the use of blood pressure drugs be raised from 130/90 to 140/90 for adults under 60 and to 150/90 for adults over 60.
  • It’s not that high blood pressure has suddenly become healthier. Rather, the experts realized that the risks of aggressive drug treatment to lower moderately elevated blood pressure outweighed the benefits. The cure was worse than the disease!
  • Fortunately, there is another option, namely the DASH diet. The DASH diet, along with a few simple lifestyle modifications, has been shown to be as effective as drugs at reducing high blood pressure without the side effects of high blood pressure medications. Both the American Heart Association and the National Heart, Lung and Blood Institute recommend that the DASH diet and lifestyle changes be tried first, before considering use of blood pressure medications.
  • Although not all experts agree, I personally recommend that you also make sure that you are getting the DV for calcium, magnesium and vitamin D from food and supplements and consider supplementing with long chain omega-3 fatty acids and polyphenols – especially resveratrol and related polyphenols from grape skins and seeds.
  • Finally, high blood pressure is dangerous. Don’t ignore it. Get your blood pressure tested regularly. If it is elevated, talk with your doctor about the best combination of diet, and lifestyle change and whether medications are absolutely necessary to keep your blood pressure under control.

Shermer’s Neck Is An Ultra-Cyclist’s Nightmare

shermer's neck pain ultracyclistShermer’s Neck is a condition where the muscles of the back of your neck become so tight that they lose the ability to hold your head up. It is a condition most frequently associated with ultracycling.

Do you love to cycle?  Perhaps you’re an ultracyclist and ride for many hours every week.  If you are, you may already know about Shermer’s Neck.

As you are well-aware, an ultracyclist leans forwardThis is called the “aerodynamic position.” When you do that, you are slicing through the wind, and you aren’t losing speed when the wind hits your chest. However, you need to hold your head up to see where you are going and maintain that position for several hours. That is what causes Shermer’s Neck.

Shermer’s Neck And The Non-Athlete

shermer's neck pain painterYou don’t have to be an ultracyclist to suffer from Shermer’s Neck. Do you do anything that has you look up for hours, such as being a house painter? Even something as simple as having your computer screen too high can force you to have your head tilted up for long periods of time while working.

If so, Shermer’s Neck can still affect you, and seriously impact your life. Fortunately, non-athletes don’t usually have as severe a problem as the ultracyclists.

Why Does Looking Up Cause Shermer’s Neck?

shermer's neck painYour posterior neck muscles primarily originate at the middle of your back, along your spine. They go up your back and neck, and insert into either your cervical spine, or the bottom of your skull. When these muscles contract, they pull your head back.  When the muscles of the posterior neck contract, if you are standing, you’ll be looking at the ceiling. If you’re a cyclist, your posterior neck muscles contract in order for you to look forward.

How To Treat The Muscles That Cause Shermer’s Neck

To treat the muscles that cause a repetitive strain injury in your neck, tilt your head back and pinch the muscle that is right next to your spine.

While pressing deeply, slowly lower your chin toward your chest so you are stretching the muscle fibers.  Don’t let your hand slide on your neck or you will miss the stretch.

Do both self-treatments on both sides of your neck.
