Memory loss – Peri-menopause or Ageing?

Todays post is about Memory loss, is it Peri-menopause or Ageing?

Over the last few months, some of my female work colleagues and I have been discussing how occasionally we find ourselves suffering from a lack of concentration, memory loss and feeling a bit ‘scatterbrained’.

This got me thinking. Is this a sign of ageing or is this is another reminder of ‘peri-menopause’? Or maybe both!

About Memory

Webster’s Dictionary defines memory as “the mental capacity or faculty of retaining or recalling facts, events, impressions, or previous experiences”. Therefore memory loss would be fleeting periods when a person loses the mental capacity or faculty of retaining or recalling information.

As we get older, one of the most common changes that we notice is memory change.

Scientists say that the brain begins to lose sharpness of memory and powers of reasoning and understanding not from 60 as previously thought, but from as early as 45.

Their evidence comes from a large study of more than 7,000 civil servants aged between 45 and 70. The 5,000 men and 2,000 women agreed to undergo verbal and written tests on three occasions over a 10-year period for what is called the Whitehall II study.

Knowledge of how memory changes as we get older is a lot more positive than in the past. Memory change with healthy ageing certainly doesn’t interfere with everyday life in a dramatic way.
However, everyone is different and the effect of getting older on memory is different for each person.
Ageing can affect the memory in different ways, such as attention processes, the ability to get new information into storage, the time it takes to recall things, and “on the tip of the tongue” experiences.

Research also suggests that immediate memory and lifetime memory do not change as we get older.

The difficulty of being able to think straight is also a common symptom associated with the onset of peri-menopause.

What causes memory loss during peri-menopause?

In the case of memory lapses, oestrogen plays a special key role. It has a large effect on the functions of the brain and influences language skills, mood, attention, and a number of other functions, including memory. Oestrogen is directly linked to verbal word fluency (the ability to remember names and words). It’s no wonder then that as a woman’s oestrogen levels begin to drop, her memory may suffer.

Many women start to experience peri-menopausal symptoms from the age of 45 onwards.

Add to that now that our memory is affected by ageing from the age of 45 onwards, ageing women have a lot to deal with.

All is not lost, as there are some things we can do to exercise our brain and improve our brain ‘fitness’.

  • Avoid harmful substances and eat a well balanced diet. Excessive drinking and drug abuse damages brain cells.
  • Challenge the brain by reading widely, keeping mentally active, and learning new skills. These pursuits strengthen the brain connections and promote new ones.
  • Make sure we get regular and adequate sleep.
  • Use a notepad and carry a calendar. This may not keep your memory sharp, but does compensate for any memory lapses.
  • Organise some of those personal belongings. Use a special place for necessary items, such as car keys and glasses.

 

All of this science is great and helps me to understand that it’s not ‘just me’, though it does not help my brain cope with the occasional lapses in memory.

However, dairies and calendars have become quite important fixtures in my life lately. This ensures I don’t forget important things. I will also keep up my creative pursuits, quizzes and crossword puzzles for that bit of ‘brain training’.

Which diet is healthier?

Todays post is about which diet is healthier for us.

This weekend I read an article in the paper about the different diets that are getting press lately. This got me thinking. There are so many different opinions and studies regarding diet and health. Many conflict each other and it gets very confusing.

I have looked at few popular diets and found research both for and against.

The Paleo diet

Promoted by several nigh profile chefs and dieticians, this emulates the diet of our hunter-gatherer ancestors. It is based on the premise that they did not suffer from the same diseases as modern humans.

This diet advocates consumption of unprocessed animals and plants, including meat, fish, eggs, vegetables, fruits, nuts and seeds.

It shuns processed foods, sugar, dairy and grains, although some of the more modern “versions” of paleo do allow foods like dairy and rice.

5 human studies have been done on the paleo diet so far. All of these studies are done with humans and are published in respected, peer-reviewed scientific journals.

The results of these studies were positive in regards to health improvements and weight loss.

The Vegan diet

The vegan diet is growing in popularity. Advocates claim that it offers various health benefits, ranging from weight loss and reduced blood sugar to prevention of heart disease, cancer and premature death.

Vegetarian and vegan diets can be healthy, but they can lack certain nutrients. You may have to use a little creativity to ensure you get enough protein, calcium, iron, and vitamin B12.

The problem, however, is that no studies exist of populations where omnivores share similar genetic profiles, similar lifestyle patterns, and similar social and environmental factors with a significant number of vegans.

Therefore, most studies on vegan diets are observational. This makes it difficult to know if the benefits observed are actually caused by the vegan diet itself. Of the 16 human based studies that have been conducted. The results of these were positive in regards to health and weigh loss.

Low carb and Low fat diets

Few things have been debated as much as “carbohydrates vs fat.”

Some believe that increased fat in the diet is a leading cause of all kinds of health problems, especially heart disease.

This is the position maintained by most mainstream health organisations. These organisations generally recommend that people restrict dietary fat to less than 30% of total calories (a low-fat diet).

However… in the past 11 years, an increasing number of studies have been challenging the low-fat dietary approach.

Many health professionals now believe that a low-carb diet (higher in fat and protein) is a much better option to treat obesity and other chronic, Western diseases.

The authority Nutrition site looks at 23 studies that compare the 2 diets.

The majority of studies achieved statistically significant differences in weight loss (always in favour of low-carb).

Keep in mind that all of these studies are randomised controlled trials, the gold standard of science. These studies are scientific evidence, as good as it gets, that low-carb is much more effective than the low-fat diet that is still being recommended all over the world.

The 5:2 diet

Then there is the 5:2 fasting diet, which is actually very simple to explain. For five days a week, you eat normally and don’t have to think about restricting calories.

Then, on the other two days, you reduce your calorie intake to a quarter of your daily needs. This is about 500 calories per day for women, and 600 for men.

There are very few studies that test the 5:2 diet specifically. However, there are plenty of studies on intermittent fasting as a whole, which show impressive health benefits.

I have just put together a small sample of the information found on 2 websites. These sites did not have any articles stating that any of these diets were ‘bad’. However, several of these diets are, at the very least, conflicting with each other, eg; Paleo & Vegan.

It is very easy to find ‘bad’ press regarding any diet. At the end of the day, each of us is different and has different constitutions. Maybe the best way to determine which diet is best for us is to listen to our bodies and take note of how we feel after eating different food groups and go from there.

We have decided some time ago, that the best basis for our diet was to restrict our intake of processed foods. We try to consume mostly whole foods and foods that have had very little processing.

We also choose to restrict our intake of wheat and sugar, as we both find we feel better without it.

Atmospheric Ions and Health

Todays post is about the affect of atmospheric ions on our health.

Recently Scott and I were discussing the benefits of spending time outdoors, in a relaxed environment. As with most people, we have found that just spending time at the park or at the beach improves our mood and sometimes our health.

This prompted me to consider if there was any documented science to support this theory.

So, I did a bit of research and am sharing what I found.

I found several scientific studies and articles discussing the relationship between the atmosphere and its influence on health and mood. I am not taking about the attitudes of others around us eitherthough this can play a part.

First, what are Atmospheric Ions?

Science has found that the atmosphere we breathe normally is full of positive and negative ions. Air ions are invisible, electrically charged molecules or atoms in the atmosphere. Some particles are positively charged and some are negatively charged.

Negative air ions (NAIs) were actually discovered more than 100 years ago.

These ions are also present in our bodies, the positive and the negative ones.

NAI’s are abundant in nature. In fact, you will find the highest concentrations of negative ions around waterfalls, on the ocean, at the beach and after a storm. They are widespread in mountains and forests.

In polluted cities, crowded areas and in confined spaces such as offices, industrial areas, schools and cars, you will find the highest concentration of positive ions. These “Concrete Jungles” minimise the natural production of negative ions by disrupting the delicate electrical balance between the atmosphere and the earth.

Positive ions have been found to have a disruptive influence on our health. Headaches, sleepiness, low attention spans and a general sense of feeling unwell are just some of the side effects of spending too long indoors.

Atmospheric ions and health

Once they reach our bloodstream, ions are believed to produce biochemical reactions. Research has found that negative ions contribute to overall well-being and health.

High concentrations of negative air ions are essential for high energy and positive mood. This is why fresh air and sunshine have an invigorating effect. Alternatively, being closed in with little light corresponds with depressed feelings.

Scientists are now working with manufacturers to develop NAI generation systems. Systems that can be used to freshen indoor air and in addition to enriching oxygen content in homes, schools, hospitals, airports, and other indoor areas.

Health benefits of NAI’s include:

  • Decreased blood pressure
  • Increased concentration and productivity
  • Improved psychological health
  • Revitalised cell metabolism.
  • Enhanced immune function.
  • Purify the blood.
  • and finally they balance the autonomic nervous system, promoting deep sleep and healthy digestion.

There was so much more information available, but it is too confusing to share.

Basically, this explains why we feel so much better after spending some relaxing time outdoors, in the fresh air.

So, we are not imagining it. It’s important to schedule a date with nature to upload on negative ions.
