Estrogen deficiency and short term memory loss

I've been reading a book from the library called "Perimenopause" by Huston and Lank (2001).  It's comprehensive and written in an easy-to-read, almost conversational style.  Here are some quotes:

"It is generally believed that women live longer than men because of the cardiovascular protection estrogen provides."  This is the cardiovascular protection estrogen provides up to menopause, when the last estrogen and progesterone-producing egg follicle is released from the ovaries.  Haha, it's good to be girly.  Take that, boys!

"Memory and other thought processes depend on adequate estrogen levels.  Estrogen receptors in your brain cells receive estrogen molecules, which then improve the transmission of impulses from one neuron to the next.  In addition, estrogen use increases the actual number of functioning nerve cells.  The more neurons you have, the larger the network of functioning nerve cells, and the better your brain functions.  Estrogen supplements in elderly women have been shown to decrease the incidence of Alzheimer's diseases (AD) by 29% (Yaffe 1998), but in women who already have AD, estrogen does not slow the progression (Mulnard 2000).  Using single photon emission computed tomography (SPECT), it has been demonstrated that estrogen-deficient women have reduced blood circulation to the brain, particularly to the areas responsible for memory.  During hot flashes, such women have even further decreases in cerebral circulation.  In fact, these women had temporary vascular changes during a hot flash typically seen in women with milk to moderate AD (Greene 1998).  Hormone replacement normalized cerebral blood flow.  This suggests that hot flashes over time could contribute to neurodegenerative changes.  Women have brain glucose needs 19% higher than men and are more susceptible to diminished circulation (Baxter 1987).  This may explain the higher incidence of AD in estrogen-deficient women than in men."  Right.   Mental note - as well as being unpleasant, hot flashes are bad for your brain.  Of course I'll probably forget this in 5minutes time.

I've been prompted to read this book by noticing that my memory has deteriorated a little in the last couple of years.  Initially I put this down to grieving, but I'm now willing to blame it on the hormones a little more.  Or decrease in hormones.  There is a lovely graph in the book showing estrogen peaking in women at around age 35, and declining thereafter at a steep and steady rate until the last menstrual period at around 50.  Jeepers, I missed that starting window didn't I.  Where was I at 35?  Oh yes, that's right, my 35th birthday passed in a haze of mastitis and sleep deprivation, with newborn Keith and almost-2-year-old-Nicole.  No wonder I couldn't have cared less about what else may have been going on in my body.  I do remember a particularly exciting day when Keith was a couple of weeks old, when he slept for 4 hours overnight for the first time.  When I got up in the morning (5am) to start the day, I felt like I could run a marathon!  Later than morning, I exclaimed to my father-in-law "I had 4 hours sleep in a row last night - I feel fantastic!"  He shook his head in disbelief.  He couldn't believe I could be excited by having 4 hours sleep, and also expressed something like "I don't know how you women cope with this." Hormones, my friend, hormones.

After being pulled over by the police recently for driving an unregistered car (I'd forgotten to pay it) and being threatened by the retailer we buy gas from that they were going to cut us off (forgot to pay that too), I've realized that relying on memory alone isn't going to cut it anymore.  I've had to set in place systems to make sure these critical things get paid.  And it seems to be working thus far (I just hope I don't lose that diary!)

I went to the shops this morning for a few essentials (hot chocolate powder, sanitary products, iced coffee - yes it's that time of the month again), and when I returned to my car, I couldn't find my keys.  Puzzled, I sat in the driver's seat and pondered my next move.  I hadn't locked the car, you see, as I locked my keys IN the car not so long ago and had to call my husband to drive to rescue me with the spare set.  I sipped my iced coffee (ahhhhhh) and wondered if I should walk home, or mount a bigger search of the vehicle, and the shop I'd just been into.  And then I saw a glint of light reflecting from something next to the steering wheel.  Yes, that's right, I'd left them in the ignition.  In the unlocked car.  Oh good.  Luckily for me the 26year old Subaru is not on the top 10 list for car thieves.

As much as I complain about these monthly bleeds, I suspect I'll miss them when they are gone, or at least, miss what they represent - my capacity to have more children.

Hormones.  Love them or hate them, they're part of who we are as human beings.  Gotta love them.

The Purpose of Suffering - part 1

Since Sophie died 17 months ago, I have thought a lot and read a lot about suffering, mostly from the point of view of the Christian believer, since that is what I am.

Two books that have been significant in my grief journey are "Stepping Heavenward: One Woman's journey to Godliness" by E.Prentiss, and "Desiring God" by John Piper.  

Elizabeth Payson Prentiss (Portland, Maine, 26 October 1818 – 13 August 1878) was an American author, well known for her hymn "More Love to Thee, O Christ" and the religious novel Stepping Heavenward (1869).  Read more about Elizabeth Prentiss here.  From the Wikipedia bio we learn that she was the 5th of 8 children, 2 of whom did not survive to adulthood.  Elizabeth herself bore 6 children, 2 of whom did not survive to adulthood.  This gave her real life experience for the central character in Stepping Heavenward, Katherine Mortimer.  The novel is set in the mid 1800's.  No antibiotics.  No physiological intensive care units.  Katherine believes deeply in the God of the Bible, and lives her whole life in relationship with Him.    Katherine's husband in the novel is a Doctor, and she would sometimes accompany him to visit the sick and the dying.  The take home message I got from this is that they accepted death as God's appointed time, and were not afraid to spend time with the dying person.  Katherine's father died from a blow to the head (accidental) when she was a teenager.  Her neighbour's child died from scarlet fever at age 4 (Nicole had the same infection at the same age, but she could take antibiotics for hers.)  Katherine's first child died from a microbial infection at the age of about 4.  What a heartbreaking way to live.  Believers were utterly dependent on God the Father/Son/Spirit for everything in their lives, including the lives of their children.  In our medically advanced first world society, I think I'd been living under the illusion that we are not as dependent as they were, but I have changed my view on that since Sophie's death.  Despite doing everything modern medicine told me to do in order to have a healthy pregnancy, I could not prevent Sophie's death.  Katherine reached a point in her life journey where she could say that if God should "ask" her for anymore of her children, she would be able to let go without anger, even though the death of her loved one would also hurt like blazes.

Katherine also spent several winters of her life incapacitated by illness.  Rather than viewing this as an inconvenience, she recognized it as a gift for a season, to immerse herself in God's Word, and so get to know Him better.  I remember another friend speaking in similar terms about the 2 years that she was incapacitated by Chronic Fatigue.  In our affluent western culture we are always in a rush.  Work - achieve - produce - spend.  I think that the enemy has deceived us into thinking that this is the way to joy/happiness.  IF we are forced to slow down we tend to think of it only in terms of loss of productive hours.

We also think that we don't need God because we have so much medical technology.  We think we are in complete control of our lives.  Medical technology is a wonderful gift, but are we valuing the gifts more than the Giver?  Of course it's only when we get to the point of valuing the Creator above all other things (yes, even above our spouse and children, should God grace us with them) that we find true joy.

Joy in the midst of suffering.  Enter John Piper's "Desiring God". find out more here

Piper says that suffering can be in the form of illness, accident, natural disaster, or direct hostility from another person.  Whatever the cause, suffering tempts us to doubt that God is Good.  Suffering temps us to doubt that God is sovereign.  Suffering tempts us to doubt that God is faithful, merciful, holy, unsearchably great.  Of course, Satan delights when we doubt any aspect of who God is, which is why he gets in our face when we are suffering and says things like "What sort of God would allow innocent children to suffer and die?"

John Piper says that when a Christian person holds onto the truth of who God is during suffering THEN those around can see the tremendous worth of Christ.  Why would we put up with or accept suffering if this life was all there is?  As Paul the Apostle said in 1 Corinthians 15 vs 19 "If in this life only we have hope in Christ, then we are of all men to be most pitied."

JP also says that in our sufferings we show a little of what Christ suffered in taking ALL of our sin upon him in order for us to be reconciled to God.

Our suffering does not change who God is.  It changes who WE are, or rather, it changes our understanding of who we are.

A few months ago a friend asked me how I felt I had changed since Sophie's death.  I replied that I had more patience than I'd ever had before, no question.  More patience with my own children, with my husband, with people in the carpark who steal my parking space.  It's not worth expending emotional energy getting upset about things that really don't matter in the long term.

In the last few months the patience has been overtaken by humility.  In realizing that I am not in control nearly as much as I like to think I am, I have learned to trust God more, trust my wonderful Ben more, listen more and talk less, and not express every opinion that I have, or even feel that I need to have an answer for everything.

All this musing is from my perspective as a Christian believer, and I acknowledge that many of my friends and family do not look at life from this perspective.  How do you journey through your grief and loss?  What do you take solace in?  Does it work?  What do you hold onto?  I would love to know your views.

Yarnbombing on KI

Let's get straight to the knitting story, shall we?

In the yarn bombing photo, you can see a rest-stop on the stair to the top of what's known as Prospect Hill, so named because Matthew Flinders climbed it to get a better view of the Island and surrounds to see what the prospects were.  The kids did count the number of steps (512 steps according to this website)  I've tried to encompass the 360 view in the other 3 photos.  The first one with the road is looking East back towards Penneshaw.  The second swings around to the SouthWest, taking in the rugged coast there, and the 3rd looks NorthWest across the lagoons towards American River.  Prospect Hill is on the narrow part of the island between the big blog and the littler blog (those are technical terms ;)

BUT back to the serious business of knitting.
What better to provide cushioning and beauty half way up the climb, than to have some yarnbombing (or yarn graffiti) on the resting seat and the balustrade itself.  I'm wishing I thought of it myself.  Now there's a thought - prepare knitting in advance for each road trip we go on, so we can leave something of beauty wherever we go......

Jerusalem Artichokes

Very Tall Jerusalem Artichokes

Looking up to the sky....

Thankyou to my fellow bloggers the Funky Frontyard Farmers (see their blog here) for inspiring me to give these JA's a try.

I think the foliage and flowers are beautiful in their own right.

This mass of flowers and stalks and leaves grew from 2 tubers (is that the right word?) that I planted last Spring.

Now that I know how tall they are growing, I am going to plant some as a curtain on one side of Sophie's garden, to make it like a secret room that you cannot see until you are almost at the front door to our home.  On the left hand side in the picture I think.  Or who knows, when we harvest the JA's, maybe there'll be enough for a curtain on all 4 sides, with a small doorway.  We'll see.

Current view from front door

 

Sophie's Garden is taking shape much more slowly than I thought (partly due to the price of water....*gasp*) but that's OK.  I had in mind that it would be ready to share with my wonderful community by the end of summer, but now I'm thinking that Sophie's 2nd Angel Day might be better, as the plants would have grown more by then, and the shape of the outdoor garden room will be more obvious.  I had lunch out there today, some homegrown tomato on some homemade bread.  Beautiful.
