all the power to change your tomorrow is in your control

You may have heard humans only use 10% of their brains. Easy to accept that idea, considering how we are aware of so many remarkable people able to do things we cannot.  We all believe in rumors and when we hear something we know we heard before, we don't question it. It allows us to assume they have unique minds, far beyond what is "normal" to the rest of us. It is the same thing with #PTSD. If we see someone who seems to be fine after surviving what caused PTSD in us, we think they have stronger minds than we do. 

The thing is, it isn't true. Appearing to be "normal" after surviving, escaping unchanged, unharmed, and unaffected, may not be something you can see with your own eyes, but you can with technology.

According to a survey from 2013, around 65 percent of Americans believe that we only use 10 percent of our brain.

But this is just a myth, according to an interview with neurologist Barry Gordon in Scientific American. He explained that the majority of the brain is almost always active.

The 10 percent myth was also debunked in a study published in Frontiers in Human Neuroscience.

One common brain imaging technique, called functional magnetic resonance imaging (fMRI), can measure activity in the brain while a person is performing different tasks.

Using this and similar methods, researchers show that most of our brain is in use most of the time, even when a person is performing a very simple action.

A lot of the brain is even active when a person is resting or sleeping.

You may be wondering, what does this have to do with #PTSD? A lot! If you believe only a tiny percentage of your brain works, you settle for what you think you can't do. You don't look for new possibilities or new things to learn. With PTSD, if you believe you have no power to do anything about it, you don't.

Think about everything that goes on in your brain. Now think of all the treatments out there that your brain needs to heal, just as much as parts of your body need to heal from wounds you can see. Just because you cannot see the wound of PTSD with just your eyes, you can see what it does to you. It may not make sense until you can see it with your own eyes. Well, actually, you can.

Scientific America
MRI studies conducted over the past two decades have found that PTSD patients with dissociative amnesia exhibit reduced activity in the amygdala—a brain region that controls the processing of emotion—and increased activity in the prefrontal cortex, which controls planning, focus, and other executive functioning skills. In contrast, PTSD patients who report no lapse in their memories of trauma exhibit increased activity in the amygdala and reduced activity in the prefrontal cortex.

“The reason for these differences in neuronal circuitry is that PTSD patients with dissociative symptoms such as amnesia and depersonalization—a group comprising somewhere between 15 and 30 percent of all PTSD patients—shut down emotionally in response to trauma,” says Ruth Lanius, a professor of psychiatry and director of the PTSD research unit at the University of Western Ontario, who has conducted several of these MRI studies. Children may try to detach from abuse to avoid intolerable emotional pain, which can result in forgetting an experience for many years, she maintains. “Dissociation involves a psychological escape when a physical escape is not possible,” Lanius adds.
The article, "Forgotten Memories of Traumatic Events Get Some Backing from Brain-Imaging Studies," is about how child abuse survivors have memories trapped, resurfacing as recovered memories. There were a lot of controversies about this because some therapists were introducing memories. This caused a great deal of research into proving how recovered memories could actually be real. In other words, like hunting for monsters under your bed when you were a child, you're hunting for the ones that hitched a ride in your brain but hide themselves in the darkness of your mind.

We all know that the only way to get rid of monsters is to confront them and stop being afraid of them. Don't fear a monstrous memory because you can defeat this one too! Now that you know the power of your brain, all the power to change your tomorrow is in your control even though you had no control over what happened to you.

250,000 radiology orders at VA canceled?

‘I knew something was not right’: Mass cancellations of diagnostic test orders at VA hospitals draw scrutiny
Donovan Slack
Oct. 1, 2018

IOWA CITY, Iowa – Radiology technologist Jeff Dettbarn said he knew something was wrong at the Department of Veterans Affairs hospital in Iowa City, Iowa, when a patient arrived in February 2017 for a CT scan, but the doctor’s order for it had been cancelled.
“To have a patient show up for a scan and not have an order – you’re like, ‘What the heck is going on?’” he told USA TODAY in an interview.

Dettbarn started collecting cancellation notices for diagnostic procedures such as CT scans, MRIs and ultrasounds.

“I knew something was not right,” he said. “Because none of them were cancelled by a physician.”

Cancellations of more than 250,000 radiology orders at VA hospitals across the country since 2016 have raised questions about whether – in a rush to clear out outdated and duplicative diagnostic orders – some facilities failed to follow correct procedures. At issue is a concern over whether some medically necessary orders for CT scans and other imaging tests were cancelled improperly.

The VA inspector general is now auditing mass cancellations at eight VA medical centers “to determine whether VA processed radiology requests in a timely manner and appropriately managed canceled requests,” VA Inspector General Michael Missal said.

Those hospitals are in Tampa and Bay Pines, Florida; Salisbury, North Carolina; Cleveland; Dallas; Denver; Las Vegas; and Los Angeles.

Many Different Wounds You Cannot See Still Just As Real

I often get offended when some folks want to say PTSD is an "invisible wound" almost as if that allows them to walk away without ever really thinking about it. 

Take all the other "invisible wounds" and then try to dismiss them. A broken bone does not always break through the skin, yet a broken bone still causes pain and needs help to heal. 

What about a headache or toothache? Can anyone see that pain? What about torn tendons or pulled muscles? Can anyone see them with just their eyes?

About six months ago I started to have problems with my left leg. I thought it would just get better, but it didn't. It got worse. After the last time I fell, I decided to go see my doctor.

He could tell I was in pain even though there was nothing for him to see as far as my leg was concerned. He sent me for an MRI. 

What if he didn't know me or the fact that I have a high tolerance to pain? What if he didn't believe the pain I was reporting was real?

It tuns out the MRI showed a reason for the pain. I have nerve damage and it has been causing the pain running down my leg. No one can see it with just their eyes. They can only tell by the way I walk that I am in pain.

With PTSD, no one can see it unless they either know the person or use a medical scan to see it. The fact is, the pain is so real inside, if you know them, you can see the pain they carry. You cannot see a lot of things unless you actually take the time and look.

We know that it is real, just as real, as traumatic brain injury, and that is what technology has proven. The pain is real but only machines can see what you feel. That is, unless you happen to be with others, who not only see your pain, but help you carry the load until they help you heal.

The longer you wait to heal, the more you torture yourself. You could be healing right now instead of suffering.

Brain's Response to Trauma, Increase Emotional Memory

This is for anyone who cannot understand what trauma does. It is not mental illness. It is not just psychological. It is also emotional. The only way to get PTSD is by surviving traumatic events. Hope you caught the word "surviving" since the victims did not survive to tell us anything. You were stronger than the event when it happened and you are strong enough to defeat it now.  Get help to fight for your life again.
Trauma Changes Your Brain’s Response To New Events, Increasing Activity In Emotional Memory Regions

“This traumatic incident still haunts passengers regardless of whether they have PTSD or not,” Palombo said. “They remember the event as though it happened yesterday.”
Following a trauma, we see the world through different eyes.

While many people intuitively agree with this statement, a new MRI study offers some hard evidence in support of this belief.

Remembering a near-plane crash they had experienced, a group of participants showed greater responses in brain regions involved in emotional memory — the amygdala, hippocampus, and midline frontal and posterior regions.

Interestingly, these same former passengers showed a remarkably similar pattern of brain activity when recalling the 9/11 terrorist attacks, which occurred shortly after the emergency plane landing, even though none of them had personal experience with the attacks.

“Mundane experiences tend to fade with the passage of time, but trauma leaves a lasting memory trace,” said Dr. Daniela Palombo, lead author of the study and a post-doctoral researcher at Boston University School of Medicine, in a press release. read more here

Grey’s Anatomy gets it right about PTSD

Grey’s Anatomy gets it right about PTSD
Kathy Quan RN BSN

LA Mental Health Examiner

The March 26, 2009 episode of ABC’s Grey’s Anatomy accurately depicts Dr. Owen Hunt’s PTSD as a a real war wound and mental illness which is treatable.

PTSD is a brain disorder characterized by symptoms such as recurring nightmares, insomnia, depression, mood swings, and high levels of anxiety. This disorder has been linked to traumatic events such as combat stress and childhood abuse. With appropriate diagnosis and treatment with a wide variety of therapies along with medication, recovery can be achieved.

Magnetic imaging (MRI) studies and PET scans have identified areas of the brain where significant changes have been seen in patients suffering from PTSD. The primary area of focus is the hippocampus which plays a big role in short-term memories and emotions. The amygdala which controls emotional memories was first thought to be the primary focus, but more recent studies have shown the hippocampus may be the real link.

Shrinkage in the hippocampus along with increased blood flow to the prefrontal cortex, the portion of the brain responsible for decision-making activities, has also been documented in the recent research. This hyperactivity in the prefrontal cortex is thought to cause an excessive reaction to fear.

UK looks at MRI scans for PTSD

MRI testing on PTSD
MRI testing in America has revealed startling differences in the brains of soldiers with combat stress
# January 27, 2009 by admin1

For the Ancient Greeks, it was a “divine madness” that infected the minds of soldiers. During the US Civil War, it became known as “soldier’s heart”. By the First World War it was called shell shock. Today, the condition is known as Post-Traumatic Stress Disorder.

The idea that war can inflict deep and lasting psychological wounds is not new. In Sophocles’s tragedies, former soldiers descend into a state of mind that would be all too familiar to modern military psychiatrists. Yet despite the passage of more than 2,400 years, our understanding of PTSD has remained surprisingly unsophisticated: not only are the underlying biological and psychological causes poorly understood, but it is almost impossible to predict which soldiers are the most susceptible.

Now, however, new research from America – triggered by the soaring incidence of PTSD among troops returning from Iraq and Afghanistan – has found striking differences in the brain patterns of those suffering from combat stress, raising hopes that we will be able to identify and treat sufferers much more effectively.

At the most basic level, PTSD is the result of a breakdown in the defence system that copes with traumatic and frightening experiences. After such events, most people will suffer what is known as Acute Stress Disorder, which involves symptoms of anxiety and depression. The majority will recover, but a minority go on to develop the chronic mental health problems that characterise PTSD.

“They get stuck in a cycle whereby recollections of a traumatic event are triggered by a particular situation they encounter,” explains Professor Simon Wessely, director of the King’s Centre for Military Health Research at the Institute of Psychiatry, King’s College London. “This triggers the symptoms, and they then try to avoid the situation that triggered the recollections – but that just means that the symptoms get worse the next time they encounter the same situation.”

“Those who develop PTSD are not necessarily the most vulnerable,” adds Professor Roberto Rona, a lecturer at King’s Psychological Medicine and Psychiatry Division. “Ideally, we would want to start treatment as soon as possible by separating those who are going to recover normally and those who will have a problem after a traumatic event.”

PTSD brain change seen on MRI

PTSD is a wound that you can see, if you happen to have a MRI

Does stress damage the brain?
Individuals who experience military combat obviously endure extreme stress, and this exposure leaves a number of diagnosed with the psychiatric condition of post-traumatic stress disorder, or PTSD.

PTSD is linked to several abnormalities in brain structure and function. However, as researcher Roger Pitman explains, Eventhough it is tempting to conclude that these abnormalities were caused by the traumatic event, it is also possible that they were pre-existing risk factors that increased the risk of developing PTSD upon the traumatic events occurrence. Drs. Kasai and Yamasue along with their colleagues sought to examine this association in a new study reported in the March 15th issue of Biological Psychiatry.

You know me too well. You saw this rant coming as soon as you read the title of the study.

Deep breath, here we go!

The SOB brass in the military had better come up with different excuses to ignore this now! Test after test, study after study and there are still some denying PTSD is a real wound. It comes from an outside force called TRAUMA! It has nothing to do with their twisted logic that if they had trained better, were not cowards or trying to "suck off the system" then they would be "real men" and do their jobs no matter what happens to them. After all, they "enlisted" didn't they?

The bullshit I keep reading from the commanders still acting as if these wounded soldiers, especially wounded Marines, should be tried as cowards, makes me want to go over to them an slap their faces or use, what my husband said should have been sent to Vietnam, my mouth! He says it's lethal when I'm angry.

If the Brass Bastards would start being ashamed of being such idiots when it comes to PTSD instead of being ashamed of the men and women under their command, this would have changed for all the wounded a long time ago. I guess their training didn't include intelligence!

Then we have the jerks within the units still acting as if the buddy they trusted with their lives is suddenly a different person instead of a wounded warrior! Do these fools ever read anything besides Play Boy? How many lives could have been saved if these Neanderthals remembered they were human as well?

I'm still getting attacked by comic book academics claiming PTSD is fake claim~
After this report, be warned, screw privacy if you email me and sound like a dope. I'll print it for the sake of the wounded you are attacking. I'd rather make you look like an idiot than lose one more wounded warrior over this.

By the way, take it seriously because as a Chaplain, I'm not going to lie.
