Hope Is on the Horizon | Three Gold Research Nuggets

ptsd

PTSD, stress, major depressive disorder – any emotional or mental set of circumstances. If you’re hurtin’ for certain, you want relief yesterday. But doesn’t it feel good (even a little) to know hope is on the horizon? Check-out these gold research nuggets…

When I was a teen, I never missed a Jerry Lewis Muscular Dystrophy Telethon. One of the things that held my attention was the fact that there really wasn’t a whole lot of hope for relief in the immediate floating around. I mean, it was really about funding research, the benefits of which were years down the road. Still, hope ruled the day, and the spirit was electric.

And so it is with the mood and anxiety disorders. Actually, there’s more available in the way of immediate relief than what existed for muscular dystrophy in the 1960s and 70s. However, the big-bangs of hope are on the horizon. Check-out three gold research nuggets for PTSD, stress, and depression…

(Looong article warning! Okay, I’m known to do that – but it’s about the info, right?)

PTSD

Massachusetts Institute of Technology researchers have extinguished deeply burned traumatic memories (in mice) by administering a HDAC2 inhibitor. It’s thought giving the drug to humans participating in psychotherapy would boost the impact of the work.

According to study lead Dr. Li-Huei Tsai…

By inhibiting HDAC2 activity, we can drive dramatic structural changes in the brain. What happens in the brain becomes more plastic, more capable of forming very strong new memories that will override the old fearful memories.

Operating under the premise the older a memory is, the harder it is to change; the research team decided to treat mice with 30-day-old traumatic memories with an HDAC2 inhibitor shortly after re-exposure to the fear stimulus. Outcome? The memories were extinguished just as easily as in mice with memories 24-hours-old.

Again, Dr. Tsai…

Our experiments really strongly argue that either the old memories are permanently being modified, or a new much more potent memory is formed that completely overwrites the old memory.

Tsai believes it’s time to start clinical trials for the treatment of PTSD , as well as other anxiety disorders, with HDAC2 inhibitors.

Stress

Collaborating scientists at The Scripps Research Institute, the National Institutes of Health, and the University of Camerino (Italy) have completed a fascinating study on stress. Seems we have a brain system that specializes in moderating its effects. It’s driven by nociceptin – and it’s become a potential intervention target for stress-related issues, as well as the anxiety disorders.

Several studies in rodents had found evidence that nociceptin acted in the amygdala (huge in memory and emotional reaction), its mission to counter the anxiety-producing effects of acute stress. The research team wanted to learn more, and here’s what they discovered. Exposure to stress generates an over-activation of nociceptin in the central amygdala. This appears to be an adaptive feedback response designed to bring the brain back to a state of normalcy.

Given what they now know, the team wants to determine if, in fact, this feedback response becomes dysfunctional in reaction to chronic stress.

Hey, compounds that mimic the action of nociceptin are in development. Some of these compounds appear to be safe and well-tolerated in animals, and could soon be ready for human testing.

Major Depressive Disorder

Okay, let’s head to Israel where researchers from The Hebrew University of Jerusalem have discovered that changes in a specific type of non-neuronal brain cells, microglia, are foundational in depressive symptoms related to chronic stress.

The team found that during the first week of stress exposure, microglia increase in size and produce specific inflammatory molecules. Then some begin to die.  When this occurs within a specific brain region involved in stress-response, on come icky manifestations such as depression.

In the lab, when the initial stress-induced activation of microglia was blocked, microglia cell death declined – along with depressive symptoms. Furthermore, when “depressed” mice were treated with drugs that stimulated microglia, and increased their number to a normal level, there was peace in the valley.

From study chief Prof. Raz Yirmiya…

We were able to demonstrate that such microglia-stimulating drugs served as effective and fast-acting antidepressants, producing complete recovery for the depressive-like behavioral symptoms, as well as increasing the neurogenesis to normal levels within a few days of treatment. In addition to the clinical importance of these results, our findings provide the first direct evidence that in addition to neurons, disturbances in functioning of brain microglia cells have a role in causing psychopathology in general, and depression in particular…

Oh, The Hebrew University has applied for a patent for the treatment of some forms of depression with several specific microglia-stimulating drugs.

That’ll Do It

So how ’bout those gold research – hope – nuggets? Yes, I know we’re not chin-deep in immediate relief options; however, just like the folks so emotionally vested in the Muscular Dystrophy Telethon, we have to keep our eyes on the horizon.

PTSD, stress, major depressive disorder – other mood and anxiety disorders – if they’re turning your life upside-down, take heart and hope in knowing creative work is being done to bring you healing. Please hang in there, k?

Many, many more Chipur articles await. Take the time to check ‘em out.

    Golden hope nuggets will go fine in a necklace of positive cheer. Thank you for researching this and bringing it to us. I know it takes time to develop new interventions and I am just glad people are doing the work needed. The glitter of hope adds a sparkle to my eyes.

      Hey, Patricia! Glad to have you back (and participating). Always a welcome addition. I’m likin’ that sparkle in your eyes, by the way. Sure wish this post was about immediate realities. Still, we have to keep our eyes on the horizon. And I assure you the research wheels are creatively rollin’.

      And, you know, here’s a consideration. It may well be that the fruits of current research labors come after our lifetimes. I mean, don’t know about you – I’m going on 60. But I have two children and a granddaughter who’s genetic make-up may manifest in a mood and/or anxiety disorder. And I feel really good knowing some of these gold research/hope nuggets, and others, will likely be a available to them.

      Please come back, k? Bill

    Woo hoo – lots of hope here, Bill – as always, actually. And you have such a knack for bringing the science to us in simplified terms we can appreciate. As you write, “just like the folks so emotionally vested in the Muscular Dystrophy Telethon, we have to keep our eyes on the horizon.” I’m with you!!! We are in a whole new world and the possibilities are endless!

      Lots of “Woo hoo” here for sure, Lisa – and thank you for your visit and comment. I know research nuggets may seem dry to some; however, they’re truly exciting. First of all, it’s gratifying to know hard work is being done to resolve mood/anxiety disorders. Secondly, the work is highly creative – working on fixes with minimal impact on our overall health and welfare. Stay tuned for even more! It’s all about sharing, learning, and healing here…

    Relief and new/innotivative treatments for PTSD (not to exclude the importance of the others)- near and dear to my heart. So glad to hear it! Thanks for presenting it all in such a way that we can understand, and take away lots of hope! Another good one Bill!

    • http://chipur.com chipur

      I remember from a previous post that the PTSD thing means a lot to you, Leslie. Glad this one connected, as well. How ’bout this? A few years back, Dutch researchers put a study together regarding the administration of the beta-blocker propranolol (Inderal) immediately after a traumatic event, and found it serves to somehow block the “burning” of the memory. Can you image? One day there may be, say, that “golden hour” after a rape or witness of a violent act to administer a med to minimize memory creation? Wild stuff, yes. And tons of hope!

      Thanks for your continued checking-in and contributing…

    I think back on the daze when my psychiatrist Dad would come home from his exhausting and stressful work day at the hospital after observing and administering the then unrefined, electroshock therapy back in the late 50’s.

    Holy plasticity, we’ve come a long way baby and thank you, Bill for this fascinating, late breaking and hopeful news.

    I particularly like this quote: “Our experiments really strongly argue that either the old memories are permanently being modified, or a new much more potent memory is formed that completely overwrites the old memory.”

    I’m rootin’ for both arguments and for you, Bill White.

    • http://chipur.com chipur

      Dang, Herby, what “daze” those must’ve been for patients – and providers with a heart. Ever since the days of the intro of Thorazine, we’ve slowly progressed. Heck, the reuptake inhibitors that arrived with Prozac are becoming old (and rough) science. Great and safe relief and healing are on the horizon. Now if we could do something about the FDA. And let’s not forget your area of specialty – wellness. Much we can be doing for ourselves while research hits home .

      Thanks, as always, for your visits and insight, Herby…
