How Spring Cleaning Can Exercise Your Brain

image One of the simple (and perhaps slightly wacky) pleasures of my life is trying to figure out how even the most mundane of tasks can be done so that they help stimulate  the brain, trigger new neural growth, and maintain old memories and skills.

This week’s focus?  That odd urge so many of us get this time of year, to clean out the corners and cubby holes of our homes.   So in between my own dust-triggered sneezes,  I’ve been pondering how spring cleaning could be used to exercise our brains.  Here’s what I’ve come up with:

1.  Refresh Old Memories

Digging through closets, project boxes, and even dresser drawers always seems to trigger old memories.  Whether it’s a box of old family photos, a blouse you wore for a special date many years ago, or scraps of wood that came from the birdhouse you built with your father many years ago,  don’t just skip over these items. Let the memories flow, and see just how much you do remember about each item.   The very process of remembering strengthens the memories, and makes it more likely you’ll hold onto them in the future.

2.  Change Your Environment (more…)

Finding Calm: Deep Breaths For Your Brain

Relaxation Toolbox:  Photo by frecuencia on Stock.Xchange Stress relief is an important part of keeping your brain healthy, and since modern life is full of ongoing stressors, it’s a good idea to keep a tool kit of stress busting techniques handy.

One of the simplest and most effective tools? Learning (and remembering!) to breathe deeply, from the abdomen.

Here’s how it works:

A Reliable Medical Memory Test You Do By Yourself.

SAGE: a self administered memory test - image by RAWKU5 on Stock.Xchng Treatments for Alzheimer’s are most effective when started early in the disease’s progression, and other causes of memory problems respond well to early treatment, too.  Unfortunately, many people hesitate to talk to their doctors about their memory problems.

Sometimes they’re worried about being laughed at and having their concerns dismissed, other times they’re afraid of confirming or admitting their fears.

And some doctors don’t give memory tests early enough.  The human-administered tests are time consuming and expensive for the doctors to do, while computer-driven and tests  can make older patients anxious (as can being quized by the doctor themselves).

That’s where the new SAGE (Self-Administered Gerocognitive Examination) test comes in.  Developed at the Ohio State University Medical Center,  this handwritten test that can take as little as 15 minutes to finish, and downloadable copies with instructions are available for free to health care professionals.

Remembering Who You Are: Genealogy For Your Brain Health

Family Tree - Image by fangol on Stock.Xcng
By now, you probably know that exercising your brain is an important part of maintaining the health of your mind and memory.  You may also know that  specially targeted brain fitness programs (like Dakim) and intellectually challenging  hobbies can be part of that exercise, helping to keep your brain fit and healthy.   This week, I thought we’d look at a popular hobby that offers a unique set of challenges to our minds and memories – tracing the family tree.

Why is it so unique? Building your personal family history starts with your own memories. Recording what you know about your family strengthens those memories, and every time you go back over that information, the neural network that supports it becomes stronger.

At the same time that you’re reinforcing old memories, you’re laying down new memories – new information that you’ll discover about family members, history, geography.

Get Moving for Your Memory (even if you’re out of shape or physically limited)

Get Moving, and Improve Your Mind! Image by hortongrou on Stock.Xchng If you’re looking for a quick brain boost, nothing compares to the benefits of physical activity.  One study after another has confirmed that exercise improves, maintains and protects cognitive functions in a whole wealth of ways( and that’s in addition to all of the other healthy goodness that being active and fit brings)

But actually *being* active?

Sometimes that’s easier said than done, especially as we age. Injury, illness, and just general out-of-shapeness make the idea of going to the gym or jogging around the park out of the question.

So what can we do, when our bodies just can’t drop to the floor and give us 100 push-ups anymore?

Six Kinds of Brain Scans: Peering Inside The Skull, Part Two

In part one, we looked at three of the older ways to get a picture of what’s going on inside the skull.  EEG’s, which use electrodes on the scalp to measure electrical activity, CAT scans, which use XRay like radiation to reveal the physical structure, and PET scans, which use a radioactive injection to reveal areas of blood absorption in the brain.

MRI scanToday, we’re going to look at three more scanning technologies used by science and medicine –  technologies that are used not only for medical diagnosis, but heavily used in research, too.

MRI (Magnetic Resonance Imaging)

MRI’s were originally called NMRI’s, for Nuclear Magnetic Resonance Imaging, but the public was skittish about the  association with nuclear radiation exposure that the name conjured up, so the N was dropped.   The fears were ironic, because unlike PET and CAT scans, MRI’s don’t expose the patient to radiation at all.  Instead, they use a combination of a magnetic field and radio waves to harmlessly distinguish between different kinds of tissues, while a computer builds a picture based on the data.

Like CAT scans, MRI’s reveal the brain’s structure, but provide much more detailed and higher contrast results, and are able to distinguish more clearly between the density in a tumor, for instance, vs healthy brain tissue.

fMRI scan fMRI (Functional Magnetic Resonance Imaging)

fMRI’s are a specialized type of MRI scan that reveals blood flow and oxygen levels in the brain. The more active an area of the brain is, the higher the blood flow is to that region, and the more oxygen is used — so fMRI’s provide a sort of second-hand look at the activity levels within the brain. First produced in the 90’s, they’ve quickly become invaluable tools in neuroscience research, and are responsible for many of the advances made in our understanding of the brain.

You’ll see fMRI’s mentioned a lot in articles about brain fitness research. As useful as the results are within the studies, the way  the information is described sometimes lead us lay folk to over simplified ideas about the brain’s function being compartmentalized, rather than working as a whole.

MEG scanner MEG (Magnetoencephalography)

MEG scans are similar to one of the of the oldest methods, the EEG; . Both scans reveal brain activity based on the tiny electrical signals produced by active neurons.   But while EEG’s measure electrical waves coming through the skull, MEG’s measure the magnetic fields of those electrical signals.   The advantage? The skull interferes with accurate measurements of the electrical signals, but the magnetic fields are less affected.  MEG scans can show changes in the brain on the fly, almost in real time – something fMRI’s can’t do.  But MEG scans are more reliable in areas close to the surface of the brain, because the deeper you look, the more the other magnetic fields within the brain itself distort the results.

So there you go.

Six brain scanning technologies: EEG, CAT, PET, MRI, fMRI, and MEG.   Between them, they can measure electrical activity, bloodflow and oxygen use, and the physical structures of the brain.  In combination, they create a fascinating picture of  how the human brain functions and responds, as well as how it changes in structure.   Knowing just a little about them provides a deeper understanding of the research behind brain fitness recommendations, which is, of course, what you’re here for!

Have you ever had a brain scan?

I have to admit to moments when I really, *really* wanted to know exactly what was going on beneath that skull of mine!

Six Kinds Of Brain Scans: How Doctors Peer Inside Your Skull (part 1)

Results of an fMRI scan done by NASABrain-scans have always sounded a bit Science-Fictiony and mysterious to me.  I love the very idea of being able to peer inside someone’s head, analyze the activity, access their memories, know what they’re thinking.

Most of that, of course, is  still Science-Fiction.   Current technology can reveal a lot about our brains, but it can’t read our minds, reproduce our memories, or project copies of our thoughts onto a TV screen.

But what technology can do is pretty amazing, and it’s worth knowing a little about the methods involved – not only because your doctor may want to have your brain scanned one day, but because it helps in understanding the research being done on brain fitness, how diseases of the brain are diagnosed and understood, and because, well… it’s just generally really cool stuff!
