MRI brain scans show FM 'brain signature'

2-2
In the study found the journal of Pain August 31, 2016 it looks like they may have found a way to diagnosis Fibromyalgia using MRI scans. They identified a brain signature that specifically characterizes fibromyalgia central pathophysiology at the neural system level using fMRI.
The study included 37 FM patients matched with 35 healthy controls; and it analyzed responses to a) painful pressure and b) non-painful multisensory (visual-auditory-tactile) stimulation with a fMRI machine. 
We used machine-learning techniques to identify a brain-based FM signature. When exposed to the same painful stimuli, FM patients showed greater Neurologic Pain Signature (NPS, Wager 2013) responses. In addition, a new pain-related classifier ('FM-pain') revealed augmented responses in sensory integration (insula/operculum) and self-referential (e.g., medial prefrontal) regions in FM, and reduced responses in the lateral frontal cortex. A 'Multisensory' classifier trained on non-painful sensory stimulation revealed augmented responses in insula/operculum, posterior cingulate, and medial prefrontal regions, and reduced responses in primary/secondary sensory cortices, basal ganglia and cerebellum. Combined activity in the NPS, FM-pain, and Multisensory patterns classified patients vs. controls with 92% sensitivity and 94% specificity in out-of-sample individuals. Enhanced NPS responses partly mediated mechanical hypersensitivity, and correlated with depression and disability(puncorrected<0 .05="" and="" clinical="" correlated="" fm-pain="" multisensory="" p="" pain="" puncorrected="" responses="" with="">
If this can be replicated this characterization based on pathophysiological, symptom-related brain features may enable for objective neural targets for therapeutic interventions. It looks to be about 93% accurate. 
"The novelty of this study is that it provides potential neuroimaging-based tools that can be used with new patients to inform about the degree of certain neural pathology underlying their pain symptoms," said Marina López-Solà, a post-doctoral researcher at CU Boulder and lead author of a study published in the journalPain. "This is a helpful first step that builds off of other important previous work and is a natural step in the evolution of our understanding of fibromyalgia as a brain disorder."
One patient advocate calls the use of MRI brain scans a breakthrough in fibromyalgia research.
"New cutting-edge neurological imaging used by CU Boulder researchers advances fibromyalgia research by light years," said Jan Chambers, founder of the National Fibromyalgia & Chronic Pain Association. "It allows scientists to see in real time what is happening in the brains of people with fibromyalgia. 
"In fibromyalgia, the misfiring and irregular engagement of different parts of the brain to process normal sensory stimuli like light, sound, pressure, temperature and odor, results in pain, flu-like sensations or other symptoms.  Research also shows that irregular activity in the peripheral nervous system may be ramping up the central nervous system (brain and spinal cord).  So the effect is like a loop of maladjustment going back and forth while the brain is trying to find a balance.  This extra brain work can be exhausting."

Signs the pain is getting the best of you

100 Symptoms of Fibromyalgia

There was a site that had this and I had linked to it on Tumblr but it is gone. So I had to hunt down someone who found my post and posted the whole thing in a forum. Anyway it is around but I'm posting it here so I will not have to hunt it down to reference it. Now we all know the major symptoms are the wide-spread pain, but our pain isn't just muscle pain... it can be nerve types of pain as well, and the fatigue and the insomnia. And even among symptoms there are some far more frequent than others, but it should be said we have categories... like the cognitive dysfunction, which is a broad one that has more than one symptom and we often just say fibrofog. The insomnia... more than one sleeping disorder. So the list is interesting.




GENERAL
__ Fatigue, made worse by physical exertion or stress
__ Activity level decreased to less than 50% of pre-illness activity level
__ Recurrent flu-like illness
__ Sore throat
__ Hoarseness
__ Tender or swollen lymph nodes (glands), especiall…

Getting through the high intensity pain flares #Blogboost

The crowded me out of the brain. Making no room for anything else. Distraction was impossible. You feel almost frantic with the pain but must be still.

What do you do? To get through it when you have no distraction?

I ask me this as I am really in the depths of a 9 level frantic level of pain right now. Hoping maybe some writing will be a distraction, but it isn't. As I said, the pain crowds the brain. I have to focus real hard to write and my head isn't clear. Too much pain to focus well. Things become quite difficult to do. 

I will say this: We cannot function. We have to just cope with the pain.

But we are Immersed in the pain, we what do we do?
We can and should rest and get through it the best we can. Here are some of the things I do to get through it.

Relaxation breathing: I can't meditate when in high levels of pain. It just makes me think about how much pain I am in. Just not a good idea. But I do do relaxation breathing. I close my eyes. I focus on my breathing. I even…
