Sleep Deprivation is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function.  A definition from Wikipedia and video clips from YouTube / Vimeo.

Main health effects of sleep deprivation
Sleep deprivation is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function. However, in a subset of cases sleep deprivation can, paradoxically, lead to increased energy and alertness and enhanced mood; it has even been used as a treatment for depression (see below). Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction. Complete absence of sleep over long periods has not been seen in humans (unless they suffer from fatal familial insomnia); it appears that brief microsleeps cannot be avoided. Long-term total sleep deprivation has caused death in lab animals.

Slow Wave Sleep Deprivation in Depression

Bill Yates
Brain Posts
21st December 2011

Sleep abnormalities commonly occur in depression and are included in the diagnostic criteria for the disorder.  Acute sleep deprivation temporarily improves the symptoms of major depression in approximately 50 to 60 percent of patients.  The mechanism for this effect is not well understood.

Sleep architecture abnormalities in depression include reduced REM latency (period of time from falling asleep to first REM period).  A significant amount of research has focused on REM sleep issues in depression.  However, other sleep architecture parameters including slow wave sleep may be involved in the pathophysiology of depression.

Eric Landsness and colleagues at the University of Wisconsin recently published a study of selective slow wave sleep deprivation in a group of subjects with major depression.  They noted previous evidence that an antidepressant effect of sleep deprivation in depression was associated with a high delta sleep ratio (percent of time spent in slow wave activity during first non-REM sleep cycle).  From this association, they developed a hypothesis that selective slow wave sleep deprivation may produce an antidepressant response.

To selectively interrupt slow wave sleep, the sleep architecture was dynamically monitored throughout the night using a technique called high-density EEG.  Slow wave sleep was interrupted by linking an audible tone during periods of slow wave sleep.  The sound was sufficient to disrupt slow wave sleep but not loud enough to produce awakening.  Subjects completed three overnight sleep sessions--a baseline session, a slow wave sleep deprivation session and a rebound session after sleep deprivation.

Time for today's entry: No going to bed until I've posted this one! I made a serious mistake yesterday and went to bed without posting a blog entry for the day. Since the stroke, I've had a terrible time sleeping, which - needless to say - is aggravating all night long and leaves me exhausted all day. I've had the problem since my first night in the hospital. The first morning after the stroke, everyone (nurses, doctors, family ad friends) would ask how I slept and my answer was "I didn't sleep at all," but everyone thought I was exaggerating and must have dozed at some points during the night. I really thought that I had lied awake all night, not sleeping, but no one thought that was likely. When I told a doctor that, he offered to have me get a sleeping aid that night so that it didn't happen again. The first night, I got Ambian, which seemed to have no effect. The following night, it was Benedryl, which also made no difference. I'm now taking a tablet of something with a name I can't seem to remember; the first night using that,Islept well and woke up convinced that the problem was solved. Then I came home.

My first night home,which you would imagine as a night of blissful sleep - my first night home in five weeks, after five weeks of sleeping in hospital beds without my honey at my side, in a strange place with noises all night long .In fact, a couple of rooms over at the rehab hospital was a stroke patient who was distressed at being there and was vocal about it all night long, waking me up repeatedly at least three different nights with his calls along the lines of: "Help me, help me, Can't someone please help me out of here? "His frail voice would call out repeatedly. Another night, ranted at his daughter on the phone:” No one has ever done this to me before - no one has ever locked me up and thrown away the key." Like that was something that a wing full of stroke patients needed to hear at 2 a.m. Along the same line, there was once a patient in the hall outside my room yelling, "I hate that everyone here treats me like a cripple! I don't want to be treated like a cripple anymore!" Why nobody (his daughter was standing next to him at the time) shushed him is beyond my understanding - certainly no one in the stroke wing needed to hear someone vent about being a cripple. We were all in that boat and not one of us felt any differently.

Inhibition of Hippocampal Neurogenesis by Sleep Deprivation is Independent of Circadian Disruption and Melatonin Suppression

Monday, July 25, 2011

I know that for 4 years after my event I was not sleeping well, sleep apnea - still unresolved, no dreaming - resolved by moving my statin and anti-depressant pills to the morning from the evening. Of course I should not have done this without talking to my doctor but hell I know more that he does how various pills affect me. Inhibition of Hippocampal Neurogenesis by Sleep Deprivation... I'm still sleep-deprived but it is better.

Abstract


Procedures that restrict or fragment sleep can inhibit neurogenesis in the hippocampus of adult rodents, although the underlying mechanism is unknown. We showed that rapid-eye-movement sleep deprivation (RSD) by the platform-over-water method inhibits hippocampal cell proliferation in adrenalectomized rats with low-dose corticosterone clamp. This procedure also greatly disrupts daily behavioral rhythms. Given recent evidence for circadian clock regulation of cell proliferation, we asked whether disruption of circadian rhythms might play a role in the anti-neurogenic effects of sleep loss. Male Sprague–Dawley rats were subjected to a 4-day RSD procedure or were exposed to constant bright light (LL) for 4 days or 10 weeks, a non-invasive procedure for eliminating circadian rhythms of behavior and physiology in this species. Proliferating cells in the granule cell layer of the dentate gyrus were identified by immunolabeling for the thymidine analogue 5-bromo-2-deoxyuridine. Consistent with our previous results, the RSD procedure suppressed cell proliferation by not, vert, similar 50%. By contrast, although LL attenuated or eliminated daily rhythms of activity and sleep–wake without affecting daily amounts of REM sleep, cell proliferation was not affected. Melatonin, a nocturnally secreted neurohormone that is inhibited by light, has been shown to promote survival of new neurons. We found that 3-weeks of LL eliminated daily rhythms and decreased plasma melatonin by 88% but did not significantly affect either total cell survival or survival of new neurons (doublecortin+). Finally, we measured cell proliferation rates at the beginning and near the end of the daily light period in rats entrained to a 12:12 light/lark (LD) cycle, but did not detect a daily rhythm. These results indicate that the antineurogenic effect of RSD is not secondary to disruption of circadian rhythms, and provide no evidence that hippocampal cell proliferation and survival are regulated by the circadian system or by nocturnal secretion of pineal melatonin.

"Your brain is like Velcro for negative experiences and like Teflon for positive ones," says Rick Hanson (1, p. 41).  When we briefly notice positive experiences they slip away the way a fried egg slides out of a Teflon-coated pan.  On the other hand, the stone age brain we inherited is wired to quickly detect and store negative experiences that may be threats.

To protect us, our brains developed superfast pathways that fire without our conscious awareness, like the reflex that yanks our hand away from something hot.  A brain scan study found that an area of the brain called the amygdala lit up faster when people saw fearful faces than when they saw neutral or happy faces (2).  Subjects remembered more fearful faces than neutral or happy faces when shown the photos a second time 24 hours later.  When information is tagged as negative the amygdala tells the brain to immediately send that information to long-term memory (1).  It is good to remember that a fearful face could mean danger.  However, playing negative experiences over and in our heads is not always helpful.

My goal for being happier is not to turn into a bubbly person who does not feel angry or sad.
My goal is to balance the good and bad.  Surprisingly being happy does not require a positive attitude.  It requires concrete action.  Meditation has a positive affect on mood (3,4), but meditation requires disciple and time.  Simpler actions can change the brain.

A Mother's Tale, Part 1

Pamela Hsieh
Rehab Revolution
13 September 2010

Part of the reason it’s taken me a few days to write this post is because it’s really long, but I thought it would provide an interesting perspective on the entire experience. It’s also very personal to me and deeply moves me as well to remember — and relive — these moments. Those of you who have stayed in the hospital due to traumatic injury will certainly relate, but I write this more for those of you who haven’t been in the situation before to help you better understand just how taxing and tedious it can be.

I was in the car a few days back with my mom, who completely without provocation started telling me her point of view on my hospitalization (I had brought up an old position I’d held the summer of 2003). It was moving for me to hear her take on the entire experience, and I thought it would provide some insight to everyone on how disability acquisition and traumatic injury can affect family members.

So I’m putting into English the words she said to me that day (and where more detail is required, added that, too). Eventually her story leads into my own words as well, to emphasize certain points, but I think it’s really important to get the gist of how a mother’s heart will break and go out to her daughter in time of severe crisis. There is nothing more beautiful than a mother’s love for her child, and I hope I’ve done it justice here.

Whenever Pamela mentions the summer job she had in 2003, I get upset. I remember she was constantly booked up with appointments (she was an independent contractor), and on the night of 6 July, 2003, we had stayed up late into the night talking, even though she had to wake up early the next morning to attend a work conference. I was so impressed with the way she was growing and maturing that our talk just went on into the wee hours of morning.

Then, on 7 July, around one in the afternoon, I got a call at my office from my husband telling me Pamela had been taken to South Suburban hospital and was unconscious. I felt instantly guilty because I thought it had to have been due to exhaustion — and caused by the sleep deprivation I’d been partly guilty of the previous night. Of course, since she’d always been healthy with no medical problems in the past, I wasn’t too worried.

At about three, I received another call from my husband, who was on the road. Our daughter had been transferred to the University of Chicago Hospitals, and apparently was on her way to the operating room!

How did passing out from sleep deprivation turn into a hospital transfer and surgery? My husband had no answers. Of course by this point I was too distracted to focus on my office work, and one of my kind coworkers told me I should take the rest of the day off, that she knew the way to the hospital and would drive me since it wouldn’t be safe for me to drive myself in such a worried state.

If you have issues sleeping, which I’ve learned if you had a stroke – you have issues with sleep, get a sleep mask.  It’s really helping me.  When I put that thing on my head my damaged brain knows to shut down.  My friend Mandy got me a sleep mask for Christmas and I love it!  Thanks Mandy.  It doesn’t work ALL the time, but it is certainly helping a lot.

Sleep and Stroke: WTF? You're Asleep Already?

Joyce Hoffman
The Tales of a Stroke Patient
Sep 30, 2013

"Are you asleep?"

I whisper the words, but loud enough for him to hear it. I don't get a response--not a foot twitch, not a hand movement, not a face gesture. I get nothing. He lies down and then, somehow, he is instantly asleep. Lucky him. But to this stroke survivor, not so fast. I often get up, in the middle of the night, because I can't fall asleep and don't want to lie there endlessly for more than two hours which is my limit, waiting for sleep to overtake me.

It's unfortunate for me that I'm so active in the middle of the night. I get up and do something else, like go downstairs to my office to write, or flip through my kids' pictures--again, or listen to the night sounds of the ocean crashing against the surf. Oh, boy. I have to get up early. The vampire, aka phlebotomist, is coming at 8. *sigh* The time is now 1 AM.

First, background is needed. The National Institutes of Health says that until the 1950s, most people thought of sleep as a short, daily hibernation from our hectic lives. What we know now, over fifty years  years later, is that our brains are busy during sleep, affecting our physical and mental functioning in a slew of ways. Sleep comes in stages:

Patience & Arriving at a Compromise

As you are already aware I have been unwell now for some time and having difficulty bouncing back.  Having used all the normal methods & practices through my recovery, I will admit to being frustrated at still feeling unwell and to me so pathetic.

I was not able to get out of bed and attempting a couple of steps was too much for my body as the condition did not allow my heart to function properly.  Okay, I get that bit but what I couldn’t quite accept was that I’ve been doing all the right things, taking everything that’s prescribed, sleeping for England, eating little and often and above all holding onto my positivity yet still nothing was improving.

Frustration hit.  Last week, I found myself believing I had changed   into a pathetic feeble individual who had somehow climbed into a body of a 99 year old, although that said there are some spritely examples of those who would currently put me to shame.

I decided enough was enough; this had to end as I had to recover the real me.  I got dressed and made my way downstairs bearing in mind it was midday by now. I had decided to decorate the Christmas tree, everything was put out for me, how could it be difficult? I had put a couple of baubles onto it and I was light headed, the pain became much worse and to breathe was agony.  As I sat down my body was totally exhausted!! You can imagine how pathetic I felt at this stage looking at the tree reminding me I hadn’t managed that simple task. A few days were like this, the tree gradually looking a little more decorated. What I didn’t realise that I was actually my own worst enemy.

Sleep: Glorious Sleep

This morning, I could not wake up. Though I tried to wake up. Kept opening my eyes and seeing, without my glasses, those blurry red numbers on the digital clock warning me it was just after 6:00 a.m.

Sleep kept slipping in sideways. Pulling me back. Even though I knew I had to get up. The home draw technician was due at 8:00 a.m. and before he arrived, I had to disconnect the feeding pump and flush Bob’s tube. Then crush and dissolve Bob’s morning medications and syringe those into his tube. Not to mention, change his bed pad and make him comfortable. And walk the dog. And feed the dog. And take my bath and get dressed. All before the lab technician arrives at 8:00 a.m. to draw blood from Bob.

But sleep has a magic power. A sort of slipping down into the gentle darkness that one cannot resist. A melting into the memory foam mattress pad on my bed.  And I grasped the safety edge of sleep and let it pull me back into the beautiful dark. Into a dream.

A dream where Bob walked and talked like he used to. Where he stood tall next to me and put his arms around me and looked down at me with those blue-blue eyes.  Where he remembered my name and brought me coffee in bed and took out the trash.  And I thought, in that dream, I just want to stay here. Stay here in this dream forever.

But my eyes fluttered open and the blurry red numbers on the digital clock read 6:15. And I thought, no, I must go back to that dream. Just for a little while, just a few more minutes. I can take the dog for a shorter walk. I just need to get back to that dream.

Stroke Rehabilitation - Thinking & Memory

Live or Die:

A Stroke of Good Luck
Friday, June 1, 2012

Stroke can cause damage to parts of the brain responsible for memory, learning and awareness.  Stroke survivors may have shortened attention spans or problems, or even loss of short term memory.   Stroke survivors may lose the ability to plan ahead, comprehend meanng, learn new tasks, and other mental activities.  Two very common problems are denial of these impairments, or any impairments, and this is complicated by the the loss of learned purposeful movement of the body.

But, as we said before, these are not problems, these are opportunities.

Tied-in are emotional disturbances.  Many people who have had a stroke feel fear, anxiety, frustration, anger, sadness, a sense of grief for their mental and physical losses.  Don't over-do, over-react.  These feelings are a natural reaction to the mental trauma. Emotional disturbances and personality changes are natural reactions.  Clinical depression, a sense of hopelessness at the inability to function is the most common disorder.  Signs of this are sleep disturbances, a change in eating patterns leading to wieght loss or gain, lethargy, social withdrawal, irritability, fatigue, self-loathing and deprivation, even suicidal thoughts.

All these things can be treated with medication and counseling.

But the medication, the most effective counseling must be helped by you, the stroke survivor.  You will make it all effective.  Remember, you've got ot put one foot down at a time, one foot in front of the other, again and again and again and again - until it's right.  It may take awhile, but the result is worth it.

Interested in the result?  Just read the book, "Live Or Die, A Stroke of Good Luck”. Dick Burns, http://www.liveordieburns.com/

My Happy Stroke
Thursday, October 14, 2010

Yesterday my father took me to the acupuncturist, Mr. Cheng.

Although my sister and father warned me that this person would be all business, he seemed very kind. Both times he ushered us to the office, motioned me to the exam table, and then said, "here's a chair for Daddy."

He examined my arm, and then he basically said, your recovery is up to you. Then he put a lot of needles in to me. Afterwards I confessed to my dad that some of the needles seemed a little too close to my spine. Fortunately, I didn't see most of them.

These days I've been having a really hard time, especially with sleep issues. But a gentle reminder, delivered with sympathy, helps me: my recovery is up to me. and of course, with a lot of support from family, friends, and therapists.

Sleep May Avert Stroke Risk

Jeff Porter
Stroke of Faith
Tuesday, April 22, 2014

As some of you know, I had knee surgery recently. One of my priorities to improve my recovery is getting enough sleep.

That just makes sense.

But the lack of enough sleep might well bring about even more serious consequences, even among the young. A recent article details how insomnia may raise stroke risk:

▶ Over the course of four years, researchers found that insomnia seemed to raise the likelihood that a person will be hospitalized due to stroke by 54 percent.

Photo from U.S. Centers for
Disease Control and Prevention
▶ That risk skyrocketed for people between the ages of 18 and 34, who were eight times more likely to suffer strokes if they had insomnia when compared to their peers who got good sleep, the study found.

▶ "We pay a lot of attention to high blood pressure, to obesity, to issues related to cholesterol. Those are known risk factors," said Dr. Demetrius Lopes, director of the Interventional Cerebrovascular Center at Rush University in Chicago and a spokesman for the American Heart Association. "But I think what is underrated is if you don't have a good sleep routine, how much it can harm you, especially at a young age."

Unfortunately, we live in a noisy, distracting, 24/7 world. And that makes it harder to get a good night's sleep. And that's on top of the difficulty many people have getting a good night's sleep even with ideal circumstances.

I love a good night's sleep. And now more than ever it seems, getting a good night's sleep is a serious matter.

Now I Lay Me Down To Sleep

Marcelle Greene
Up Stroke
Friday, August 12, 2011

When my husband and I were dating, he took me on a hike. After a couple hours of climbing, I needed a nap. I stepped off the dirt trail onto the rocky slope and lay down. I slept for an hour, amusing passing hikers and giving my husband a foretaste of our traveling life together. I have missed great swathes of Africa and Asia curled in the womb of the passenger seat while my husband serves as both driver and navigator.

Like everything else, the stroke has changed my ability to snooze easily. I put on the foot brace, the arm brace, and position the pillows just so – then get an itch under my left shoulder blade. Or I struggle to pull the covers over my icy left side and, in the process, break a sweat that requires everything to be thrown off again.

Thankfully, I am now able to sleep on my sides for brief periods. But this requires rearranging everything, so rolling over is a major commitment. And getting up in the night? To ambulate, the boot has to come off. Sometimes those devious Velcro straps conspire to stick to each other while I'm in the bathroom so that I have to pry them apart one-handed in the dark when I get back.

I spend plenty of time lying awake, my husband snoring happily beside me. My solution: audio books on iPod. Now if only I can figure out how to stop the earphones tangling.

Mentors can be Friends to Man and His Best Friend

A few months ago I wrote an article about clients and patients of speech language pathologists, and how I considered most of those I work with as “friends.” There was some flack from other speech language pathologists in the field, but it was soon quelled as I defined what a friend to me, was. As stated then, Webster defines a friend as a person whom you like and enjoy being with; a person who helps or supports someone or something; one attached to another by affection or esteem.

My Friend and Mentor Armando Cruz
(My dog Jackie’s friend also!)
This article is different. Mentors are those who communicate with you. They share information, they teach, advise, and express events of their lives that may help those with whom they speak. The Mentor I wish to write about today is a man of varied talents, and one who manages people. He is a physicist, salesman, corporate sales manager, husband, father, RVer, patron of the cinema, and just a friendly guy! He is very likable; even canines like him. He always has a pocket full of dog treats, even when he is wearing formal work attire!

Why do I write about this mentor and fine human being?  He is friendly, and always shares what he has: food he prepares, cigars and coctails occasionally consumed. He is always finding something that he thinks you would need or like when he goes shopping. Almost every time he visits, he comes bearing gifts for everyone; including (Jackie). Quite a remarkable person, isn’t he? He is always chuck full of information that he thinks might be beneficial for you, whether it is about finance, business, cooking, food, motorhomes (of which we have recently purchased), and the proper care and maintenance of them.

There are two Ways to Recover from Stroke

Peter G. Levine
Stronger After Stroke
Friday, February 27, 2015

There are two ways to recover from stroke. And they correspond to two of the four phases of stroke.

Let me start with four phases of stroke:
1. Hyperacute
2. Acute
3. Subacute
4. Chronic
For the sake of brevity let's cross off the top two:
1. Hyperacute
2. Acute
Recovery doesn't really happen during those two.

(I'll put why those two phases are important - outside of recovery per se- at the bottom of this entry).

Recovery – broadly defined as "getting better" – happens during the subacute and chronic phases.

The subacute phase: (from approximately the first week to approximately the third month – although this can vary wildly from survivor to survivor)
