Reading comprehension is the ability to read text, process it and understand its meaning. An individual's ability to comprehend text is influenced by their traits and skills, one of which is the ability to make inferences. If word recognition is difficult, students use too much of their processing capacity to read individual words, which interferes with their ability to comprehend what is read. There are a number of approaches to improve reading comprehension, including improving one's vocabulary and reading strategies. A longer definition comes from Wikipedia

    "With half a million copies in print, How to Read a Book is the best and most successful guide to reading comprehension for the general reader, completely rewritten and updated with new material. Originally published in 1940, this book is a rare phenomenon, a living classic that introduces and elucidates the various levels of reading and how to achieve them—from elementary reading, through systematic skimming and inspectional reading, to speed reading. Readers will learn when and how to “judge a book by its cover,” and also how to X-ray it, read critically, and extract the author’s message from the text. Also included is instruction in the different techniques that work best for reading particular genres, such as practical books, imaginative literature, plays, poetry, history, science and mathematics, philosophy and social science works. Finally, the authors offer a recommended reading list and supply reading tests you can use measure your own progress in reading skills, comprehension, and speed."

    SSTattler: After my stroke it was impossible to read or write - it seems to reading weird "Greek" or some other strange language. I know exactly what is the phonetics, grammar, and semantics (my previous job to build many "compiler" for formal languages) but I'm lost for the specfic language "English". I've got 1 hour in two days per week in about 8 months from the professional Speech Therapy but mostly "Speech" Therapy but little "reading" text. Eventually, I tried for myself, first simple books (like "Dick and Jane") and then, about 3 or 4 years later, I started reading relatively complex books e.g. "Zen and the Art of Motorcycle Maintenance" (philosophy ) & "Steve Jobs" (biography) & ... and so on. I'm reading books slowing after my stroke but every day gets a little better and better.

    How Does Your Brain Learn To Read?

    Published on Aug 13, 2015

    Most Americans learn how to read around the age of 5 but for some it can take much longer, why is it so hard to learn how to read?

    Brain Waves Show Learning to Read Does Not End in 4th Grade 
    “Teachers-in-training have long been taught that fourth grade is when students stop learning to read and start reading to learn. But a new study tested the theory by analyzing brain waves and found that fourth-graders do not experience a change in automatic word processing.”
    After Learning New Words, Brain Sees Them As Pictures 
    “When we look at a known word, our brain sees it like a picture, not a group of letters needing to be processed. That's the finding from a new study that shows the brain learns words quickly by tuning neurons to respond to a complete word, not parts of it.”

    When the Words Don't Come...

    Stroke of Faith
    Wednesday, March 31, 2010

    Ever struggle for the right word?

    For most people, that happens from time to time. But for some stroke survivors, that struggle happens every day. The next few blog entries will include some resources about stroke-related aphasia - problems that arise when your someone's speech is affected.

    A reference from
    There are many ways a stroke can affect a person’s ability to speak. Symptoms are typically related to the specific area of the brain affected, as language function in the brain is localized inside highly specialized areas such as Broca’s, Wernicke’s, and other areas.
    In my case, I couldn't say a word initially, and hours later, was able to struggle some words. Not all of them made sense. Some were the wrong word. Others just gibberish. And not only speech, but reading and writing were affected as well.

    Talk about frustration. I was writing for a living, based on questions I posed and answers I wrote down. That was all suddenly taken away.

    Not only frustrating, but incredibly frightening.

    I slowly regained reading and writing skills. But still, I wonder when I stumble in speech: Would it have happened if my stroke had never happened?

    Lessons Learned from a Successful Stroke Rehabilitation

    A Stroke of Luck
    December 4, 2013

    In February it will be four years since Alex’s stroke and 6 years since the ordeal began. As we move into the holiday season, Marc and I find ourselves reflecting on the entire process and discussing what helped our story to be one of inspiration – our Stroke of Luck so to speak. We started compiling a list of what we learned and how we applied those lessons with positive results. Our plan is to share our list with you in parts so that you can make sense of it in “bite-size” pieces. We welcome comments, suggestions, and questions. We hope that you will pass it along to others who might be helped.

    Here is our first installment:

    1. The Myth of One Year – Over and over again we heard that we could expect most of Alex’s recovery to occur during the first 6 months and almost all of her recovery to occur within the first year following her stroke. This caused us to panic as the months ticked away. Fortunately, we did not let up on our efforts. Alex continues to improve and “recover.” During this fourth year of recovery, we have seen impressive improvements both mentally and physically. Alex’s reading fluency and comprehension have improved – she is now able to read to learn rather than just learn to read. She is writing faster and better. And her speech is much more fluid with improved vocabulary. Her physical improvements include a better gait when walking. She can even “run” for short distances on the tennis court. We are most excited to report that she is just now beginning to use her right hand for some daily living tasks.  The message here is that you cannot give up. Do not place a time limit on your rehabilitation efforts. Rehabilitation centers will release the patient from therapy. This does not mean that you as the caregiver can stop working for more recovery on your own – even after several years.

    Twin Studies of Reading Disorder (Dyslexia)

    Bill Yates
    Brain Posts
    Posted 16th October 2012

    In a previous post, I reviewed recent research into the prevalence of reading disorder, commonly called dyslexia in children and adolescents.  The estimated prevalence for dyslexia in girls is estimated at about 7%, while in boys it is estimated as high as 14%.  Research confirms high rates of dyslexia in both boys and girls with a diagnosis of ADHD.

    Twin studies can provide valuable insight into the contribution of genetic and environmental differences in a variety of developmental disorders.  The role of genetic influences can be determined by analyzing concordance rates between monozygotic twin pairs compared to dyzygotic twin pairs.

    Support for a genetic contribution is found when the rates of concordance for a disorder is higher in monozygotic twins than in dizygotic twins.

    There are several excellent twin cohorts that have been studied for reading ability and reading disorders.  I will summarize some of the recent research on this topic from two recently published free access manuscripts.

    Hensler and colleagues from Florida State University conducted a study of 1024 first grade twin pairs from the Florida Twin Project on Reading.  In this study, all subjects in the study completed the Stanford Achievement Test-Reading subtest (SAT-10) a validated measure of reading ability.

    New Year's Resolutions for Everybody -- EVEN ME!

    Joyce Hoffman
    The Tales of a Stroke Patient
    Dec 19, 2015

    I think of myself as more "normal" now, not altogether damaged by the stroke, thanks to the help of my therapist, Theresa, who says, "Everyone is damaged. It's called 'being human.'" I believe her now. And thus, even though I write the blog "The Tales of a Stroke Patient," I'm not as damaged as I thought. I now say, "Damage is a state of mind." I believe that, too.

    I call this post "New Year's Resolutions for Everybody" because I think of myself as just a human now, one of the bunch, not especially damaged, struggling with life's obstacles put in my path to make me stronger. "Deal with it," I now say to myself. "Get over it." "Stop it." Expressions like that. So now, having my life almost in order (I'm still seeing Theresa though), on with my resolutions! As my mindset has changed, I promise myself:

    #1: to revise my bucket list to include things, with assistance, like shopping and visiting favorite people in New York and traveling across the United States. In fact, I'm going to travel in the spring, headed for Nashville again, my favorite place to be with the Grand Ol' Opry's headliners, musicians filling the streets on Broadway, and southern cooking everyplace.

But is she reads out loud, she gets hung up on many of the words (especially the little ones) and has a hard time understanding the meaning. For example, she was trying to read the title of the book “Don’t Leave Me This Way”, and had a really hard time, especially with “This”.

    E-Books After Stroke

    Rocky Mountain Stroke Survivor
    Posted on May 21, 2013

    I have always loved books and reading. Just holding a book in my hand is soothing. I love the feel, the smell, the weight in my hand. I also love reading the words, learning something new, being transported to another place. I love books in which the writing is so good, you don’t even notice it. I love books in which the writing is so clever, you can’t help but notice it.

    With the strokes, I had trouble reading. Part of it is just the fatigue. Nothing like a good book to put you to sleep when you are sleepy already. A good friend always selects books to loan me when I’m under the weather or housebound for any reason and usually I drown myself in them. Even though I did practically nothing for weeks after my strokes and am still doing very little compared to previously, I struggled to read through a full book. The problems were largely mechanical. It is really hard to hold a book open for very long. The dizziness makes the words on the page really swimmy. When I’m feeling crappy (which is when I prefer to read), the simple mechanics of turning the page is exhausting to me. Carrying a heavy book uses spoons I just don’t have.

    Technology & Research are Key Helpings of Brain Food

    Tim Seefeldt
    Brain Food Cafe for the Mind
    Posted May 21, 2015

    I always talk, think and write about being back to normal. After a stroke, that’s what a fella wants. Normal = good. You want to blend in. At least for me, there’s still a fear that somebody will notice a slight hesitation in my speech or catch me struggling to retrieve a memory. If a regular Joe or Jane forgets a name it’s just a sign of a busy life. If someone whose brain has been sizzled does the same, could it be a sign that they aren’t firing on all cylinders? Are they damaged goods? Are they capable? Do they require pity? Arggg! I imagine it’s much the same for folks who’ve suffered other assaults on their minds. The fact is though, that you’re never the same after your brain has been blitzkrieged. The difference can be in how you feel, how you function or both. It doesn’t mean that you’re not capable.

    But it might mean that you need some help or tools to do what you used to do. Imagine if a mind like Stephen Hawking’s was trapped inside his disability? What if he was born in a time and place where sharing his mind with the world wasn’t possible? Or if his part of the world had been cut off from the possibilities that helped set his brain free? I fear that that could be happening today. I’m actually pretty sure that it is. I’m certainly not in Hawking’s league. But whatever I have to offer would be largely muted without the help of technology.

    As I’ve written before, even the healed Tim Seefeldt’s reading speed is just over 50 words per minute. An average person reads at between 150 and 190 words per minute. You can’t do the work I’ve done through my career without being able to read and write. And, you sure can’t write without being able to read. Or to find a cheat. It doesn’t take a mind like Hawking’s to figure out that I’d be up the creek without a little help. More than a little. My equalizer is software originally designed for kids with learning disabilities called WordQ. WordQ literally allows me to keep up to the rest of you in reading the reams of material that comes across my computer each day. It allows me to edit my own writing to make sure that it’s up to snuff. I use it to edit and review everything I spit out, with the exception of very short emails. Bottom line is, without it, I don’t make a living the way I’ve been trained to make a living and I’m in a spot of bother when it comes to paying the bills.

    Excitement as Feedback Begins

    Box of books
    It is now a week since my book, ‘Two Strokes Not Out’ has been in print and although I was slightly concerned at how few people know about it, the feedback I am beginning to receive following the sales so far, reminds me exactly why I wrote it. I couldn’t ask for more.

    Feedback and response received from fellow survivors, carers, family members of stroke survivors and from people not directly touched by stroke and I hope will not be.

    Each individual response has been both powerful and emotional, thanking me for highlighting and/or identifying with issues that have otherwise gone unnoticed, especially for the carers and other family members. I touch on the fact that as a Stroke Survivor, we are regularly asked “how are we” yet the carer is rarely asked that question and expected to simply deal with their emotions along with everything else’s and all that is asked of them.

    It was rewarding to hear the book has helped people in different ways with different aspects so again not only one area of help or one group of people.

    I can now concentrate in promoting it in the knowledge it will help as I had intended and hoped. Also by selling copies I can create greater public awareness of people at risk of certain types of stroke, those that can be prevented by making certain changes, therefore preventing more people ending up as I have.

    It can do its work in many ways and hopefully, once read, it can be passed onto someone else to help them and their family too.

    Please consider buying a copy to help me to help others. Thank you.

    An Amazing Stroke Survivor Narrative

    Living After Stroke
    Since I started year 4 of fighting stroke deficits, I’ve been overdoing it.  This weekend I took a forced break (my body said “no more” and shut down).  I spent the time in bed reading a stroke survivor book.

    You just have to read this book, it is by far the best book written by a stroke survivor.

    This is not the typical, I fought my way back, I work, I run, I fully recovered, and life is great, type of story. By the way, only 10% of stroke survivors can tell that story. Please don’t compare yourself to those survivors.

    They did work their asses off and I applaud them but almost every survivor works their asses off, 90% of them, without those results. The ones who fully recover had a bit of luck on their sides too.

    This is a –

    Find your passion and use it to fight the stroke effects every single day and continue to fight even when you don’t see the results you expect;


    Strokes suck but learn to accept and adapt to your deficits without giving up on future improvement

    -type of book.

    The book is Stroke After Stroke; a rower’s pilgrimage written by Barb Polan.

    This book should be given to every stroke survivor with their hospital discharge papers. (To read when capable of course. It took me a good year before I could read a book.)

    Barb’s honest and pleasant approach to the horrifying subject of stroke recovery is beyond refreshing. No false positivity, no negativity, just realistic & honest never give up optimism.

    I wish I would have read it sooner but by the time I learned about it, I had already struggled through some pretty useless, miserable and negative survivor narratives, turning me off from reading anymore of them. I also didn’t think I’d have an interest in the rowing aspect.

    Day 7 I am Thankful, Gratitude Journal

    November 7, 2015

    I am grateful to be forever learning. I truly learn something new everyday. Sometimes it is about myself. Sometimes it is random facts at trivia night. Occasionally it is a life lesson.

    I like to read. I can not read as much as I used to pre-stroke. I have improved my reading time from not finishing a page without crying, to reading a book in a couple of days. Pre-stroke, I could read a book in a day if I tried.

    My short term memory is not the same as pre-stroke either. Recall could take longer, or I might not be able to recall at all. Thankfully, this seems slightly better now.

    In the future, I still hope to learn more about real estate investing, solar energy setup, and more that I can not recall now…lol.

    A Bedtime Story

    Marcelle Greene
    Up Stroke
    Wednesday, November 19, 2014

    I always have loved to read in bed. I was the kid who hid under the covers with a flashlight reading long after “lights out.” In marriage, my tired husband complained: “How much longer are you going to have that light on?”

    After the stroke I tried to read in bed but, with one hand, I couldn’t position the pillows comfortably behind my back; I got tired holding the book open single-handed, and frustrated trying to turn the pages. I gave up on physical books and started listening to audio books. After a year of buying audio books through, I discovered I can borrow them free over the Internet from my local library. When I’m uncomfortable and can’t sleep, listening to an audio book is a good distraction. The major drawback is that many books I want to read aren’t available in audio format.

    Recently, my husband and I went shopping for a new mattress. I was lolling on one when the salesman pushed a button that raised my head and knees. “Hey,” I thought. “This is comfortable. I could read an actual book in this position!”

    We bought the adjustable frame in addition to a new mattress. The first night at home with it, my husband came into the bedroom and said, “It’s good to see you reading again.” It’s a piece of our old life rediscovered. He hasn’t even complained about the light being on when he goes to sleep.

    Musing: New Carnegie Mellon Research Reveals Exactly How the Human Brain Adapts to Injury

    Dean Reinke
    Deans' Stroke Musing
    Friday, July 5, 2013

    If they know how have your doctor contact them for solutions. How do you engage your backup? New Carnegie Mellon Research Reveals Exactly How the Human Brain Adapts to Injury.

    For the first time, scientists at Carnegie Mellon University’s Center for Cognitive Brain Imaging (CCBI) have used a new combination of neural imaging methods to discover exactly how the human brain adapts to injury. The research, published in Cerebral Cortex, shows that when one brain area loses functionality, a “back-up” team of secondary brain areas immediately activates, replacing not only the unavailable area but also its confederates.

    The human brain has a remarkable ability to adapt to various types of trauma, such as traumatic brain injury and stroke, making it possible for people to continue functioning after key brain areas have been damaged,” said Marcel Just, the D. O. Hebb Professor of Psychology at CMU and CCBI director. “It is now clear how the brain can naturally rebound from injuries and gives us indications of  how individuals can train their brains to be prepared for easier recovery. The secret is to develop alternative thinking styles, the way a switch-hitter develops alternative batting styles. Then, if a muscle in one arm is injured, they can use the batting style that relies more on the uninjured arm.

    For the study, Just, Robert Mason, senior research psychologist at CMU, and Chantel Prat, assistant professor of psychology at the University of Washington, used functional magnetic resonance imaging (fMRI) to study precisely how the brains of 16 healthy adults adapted to the temporary incapacitation of the Wernicke area, the brain’s key region involved in language comprehension. They applied Transcranial Magnetic Stimulation (TMS) in the middle of the fMRI scan to temporarily disable the Wernicke area in the participants’ brains. The participants, while in the MRI scanner, were performing a sentence comprehension task before, during and after the TMS was applied. Normally, the Wernickearea is a major player in sentence comprehension.

    Okay. I apologize. Some of y'all are much younger than I am. RIF (Reading is Fundamental) is the largest nonprofit organization for literacy in the US and it was founded way back in 1966. Yes, I remember back that far too. Their goal was to put a book in every child's hand to encourage reading. It's a fabulous group. So what does this have to do with stroke survival? Well, I was getting to that.

    One of the areas I was hit hardest by my strokes was in the ability to read written words and follow it through with comprehension. This may boggle your mind because I'm writing and editing this blog. The brain after a stroke or other insult injury is a curious thing. Yes, I used the word "insult" on purpose. According to my dictionary it means...

    Caregiver: Slipping Sideways

    The Pink House On The Corner
    Friday, January 29, 2016

    I went to my therapist last week, told her I felt I was sliding backwards and she told me to think of it more as a "slipping sideways" instead.

    This whole thing with Chris has really affected me.  She is still in a coma, now diagnosed with a MRSA infection in her lungs, and, according to her daughter, "it does not look good".

    I have not been to see her, as she is in ICU and that's "family only" though her daughter said she would take me -- I just can't do it. All the memories of Bob's hospitalization back in 2010.  Memories of his recent death, flooding back on me, in gruesome detail.

    As my therapist said, "it doesn't do you or Chris any good, if you show up and fall apart in front of her."

    So I sent flowers, not even sure if she'll notice...

    On top of this, the flea problem in her apartment has escalated.  I mean the things jump out the door and attack you before you EVEN step inside.  I called a professional exterminator who has sprayed twice, but says Chris has "too much junk" piled against the walls, etc. and to work effectively, I'd have to remove stuff and pull out all her bedding, clothes, rugs etc. and wash everything....  Something I certainly am not comfortable with....

    Half an hour later, just by chance, a door-to-door baby photographer happened to ring the doorbell, hoping to make a sale. 'Good morning, ma'am', he said, 'I've come to...'

    'Oh, no need to explain,' Mrs. Smith cut in, embarrassed, 'I've been expecting you.'

    'Have you really?' said the photographer. 'Well, that's good. Did you know babies are my specialty?'

    'Well that's what my husband and I had hoped. Please come in and have a seat!.'

    After a moment she asked, blushing, 'Well, where do we start?'

    'Leave everything to me. I usually try two in the bathtub, one on the couch, and perhaps a couple on the bed. And sometimes the living room floor is fun. You can really spread out there.'

Yet the reading experience has not evolved in more than 2000 years despite storytelling taking disruptive leaps forward with the introduction of film and video games. Booktrack is his answer to addressing the decline in reading and literacy rates that will help make reading relevant again to a new generation of readers. Prior to Booktrack, Paul flew with the Royal New Zealand Air Force in roles including fisheries and customs surveillance, search and rescue, and anti-terrorism. Paul then founded a new division of an electronics and software company that provides products and services to the global defense industry, before cofounding Booktrack.

As the chair next to me became free, a young chap sat in it and the first thing I noticed was how lovely he was smiling. Shortly afterwards he apologised to me for smiling at me when he didn’t know me, I replied it was lovely and added if more of us smiled more often what a friendlier place it would be, smiles after all are contagious. Just prior to this, apart from the classical music in the background, the waiting room had been silent yet as we spoke a lady close to us joined in and shortly afterwards another lady too. Then when someone I knew entered the room a different lady offered to exchange seats so we could chat to one another, yet a conversation continued around us, all because of a smile.

    It doesn’t cost anything to smile so if this can begin in a short space of time in this environment, think what a difference we could all make if we tried to make it a habit. Promise ourselves that we won’t care what others may think of us but we will smile at least at one person we don’t know, next time we go out. If they don’t smile back, it doesn’t matter we do not know what may be going on in their lives, but that smile gifted upon them may just have made their day and at the very least they will have felt good from seeing and receiving a smile. We can then make that a habit, which apparently we only need to repeat for twenty-eight days to make it become a habit. This would make the person receiving, possibly without even realising smile back and a third person would see that and so it goes on. As the saying goes: smile and the world smiles with you.

    I came away from the doctors with this still in mind, so much so I discussed it and I’ve written this; so why don’t we all for the next week at least put it into practice, and see how we feel. I would be shocked if anyone said they didn’t feel better and lifted themselves by this simple, effortless and free action. Think also while you are smiling it takes fewer muscles to smile than it does to frown and therefore we are creating fewer wrinkles at the same time! Win, win don’t you agree?

    So, are you going to smile with me and see how we get on?

    'Smart Glasses' Offer Help to Near-Blind People

    Published on Jun 17, 2014

    Learn more about Oxford 'smart glasses' here:

    Professor Stephen Hicks and his colleagues explain the technology behind their smart glasses, sensing and redisplaying depth and outline information to allow partially-sighted people to navigate.

    The world can be a difficult place for people with limited vision. While many legally blind folks can differentiate certain objects that are in front of them, the real world normally doesn’t provide enough contrast for them to see what’s just ahead. To help take advantage of their limited vision, researchers at Oxford University have developed an electronic glasses system that helps to outline the nearby objects in front of the wearer.

    The system consists of a pair of glasses that are equipped with a camera and a display unit that can overlay images onto the glasses for the user to see. A small computer hooked up to the glasses runs the algorithms that identify objects in front of the camera and creates a high-contrast outline that the person sees in the display. Here’s a video from Oxford showing off the glasses with some thoughts from the trial participants that were the first to take advantage of the smart glasses.

    Neuroregeneration refers to the regrowth or repair of nervous tissues, cells or cell products. Such mechanisms may include generation of new neurons, glia, axons, myelin, or synapses. Neuroregeneration differs between the peripheral nervous system (PNS) and the central nervous system (CNS) by the functional mechanisms and especially the extent and speed. When an axon is damaged, the distal segment undergoes Wallerian degeneration, losing its myelin sheath. The proximal segment can either die by apoptosis or undergo the chromatolytic reaction, which is an attempt at repair. In the CNS, synaptic stripping occurs as glial foot processes invade the dead synapse.

    Nervous system injuries affect over 90,000 people every year. It is estimated that spinal cord injuries alone affect 10,000 each year. As a result of this high incidence of neurological injuries, nerve regeneration and repair, a subfield of neural tissue engineering, is becoming a rapidly growing field dedicated to the discovery of new ways to recover nerve functionality after injury.

      Neuroregeneration From Wikipedia,
           the free encyclopedia

      SSTattler: I was / am a beginner at (human) biology at high-school - I had to read this Neuroregeneration for Wikipedia many times but eventually it made sense. If you are a beginner, like me!, read the definitions 1) The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord. The 2) peripheral nervous system (PNS) is the part of the nervous system that consists of the nerves and ganglia on the outside of the brain and spinal cord. Then you can tackle Neuroregeneration... and I think it will make sense!

      Neuroregeneration refers to the regrowth or repair of nervous tissues, cells or cell products. Such mechanisms may include generation of new neurons, glia, axons, myelin, or synapses. Neuroregeneration differs between the peripheral nervous system (PNS) and the central nervous system (CNS) by the functional mechanisms and especially the extent and speed.

      Nervous system injuries affect over 90,000 people every year. It is estimated that spinal cord injuries alone affect 10,000 each year. As a result of this high incidence of neurological injuries, nerve regeneration and repair, a subfield of neural tissue engineering, is becoming a rapidly growing field dedicated to the discovery of new ways to recover nerve functionality after injury. The nervous system is divided into two parts: the central nervous system, which consists of the brain and spinal cord, and the peripheral nervous system, which consists of cranial and spinal nerves along with their associated ganglia. While the peripheral nervous system has an intrinsic ability for repair and regeneration, the central nervous system is, for the most part, incapable of self-repair and regeneration. There is currently no treatment for recovering human nerve function after injury to the central nervous system. In addition, multiple attempts at nerve re-growth across the PNS-CNS transition have not been successful. There is simply not enough knowledge about regeneration in the central nervous system. In addition, although the peripheral nervous system has the capability for regeneration, much research still needs to be done to optimize the environment for maximum regrowth potential. Neuroregeneration is important clinically, as it is part of the pathogenesis of many diseases, including multiple sclerosis.

      Hypertension Treatment with Renal Nerve Ablation

      Posted 10th December 2010 

      The neuroscience of hypertension covers several important domains.  Untreated hypertension can lead to central nervous complications such as stroke and vascular dementia.  Patients with essential hypertension show hyperactive renal sympathetic nerve outflow.  This produces several effects increasing blood pressure including: stimulation of renin, increased kidney sodium reabsorption and reduced blood flow to the kidney.  The kidney signals the brain areas controlling central sympathethic tone regulation.

      Diet, weight loss and pharmacotherapy form the basics for treatment of hypertension.  Despite a variety of drugs with different mechanisms of action many patients fail to achieve satisfactory blood pressure control.  Obviously, new strategies for blood pressure control are needed.

      One surgical strategy undergoing study is use of a endovascular cather to interrupt signals from the renal nerves to the kidney.  A recent study published in Lancet (The Sympliciity HTN-2summarized promising results from a randomized clinical trial using renal sympathetic denervation in a group of patients with treatment-resistant hypertension.  The key design elements of the study were:

      Brain Plasticity Will Blow Your Mind

      Rebecca Dutton

      February 6, 2013

      New research on brain plasticity will blow your mind.  One amazing finding is that new stem cells are produced in the lateral ventricles of the adult brain (1).  What is even more amazing is how these stem cells migrate from the back of the brain to the olfactory bulb in the front of the brain (2).  Using time lapse imaging scientists have been able to watch stem cells latch onto a blood vessel highway and drag themselves to their destination.  First, brain chemicals push stem cells away from their birth place.  Additional chemicals stop the stem cells from getting off track along the way.  As the cells approach their destination more chemicals pull them in the right direction.

      Equally amazing is the fact that new stem cells are produced in the hippocampus that controls memory (2).  Since learning is life-long, it is hard to believe that neuroscientists used to believe that remembering everything we learn can be crammed into the memory cells we were born with.  The adult brain grows thousands of new stem cells in the hippocampus every day (3).  Diffusion tensor imaging allowed scientists to see significant microstructure changes in the hippocampus after two hours of training (4).

      Oh, What a Feeling!

      My loss of sensation was as concerning as my loss of movement. In the hospital, family members would touch my fingers or toes and ask, "Can you feel this?"


      Not only did I lose sensation in my lower limbs, I could not place them in space. With my eyes closed, I could not tell if my arm rested by my side or in your hands. My perimeter had become fuzzy.

      As feeling began to return in those early weeks, I qualified it: There was vibration and pressure, but not touch – no sense of skin against skin or the texture of bed sheets.

      Temperature returned during a rehab shower – strange signals from my left leg. My right leg felt hot water. So, this is what hot feels like, I told myself. To this day my left side feels heat more keenly than my right. Hot is insistent.

      A different sensation emerged one day as my occupational therapist worked with my arm. Her hands were cold. And so this is what cold feels like, I instructed myself. Cold is subtle – it reveals itself from a distance.

      Without looking, I still cannot tell if my fingers are open or curled – grasping an object or empty. To test my sense of touch, I ask my husband to brush a cotton swab beneath my fingertips. With eyes closed, I try to tell which finger he's touching. For the first time last week, (15 months post-stroke), I was finally able to identify each finger correctly.

      Who knew that having my husband tickle me with a Q-Tip could be so exciting?
