Welcome to Chipur! If you’re struggling with a mood or anxiety disorder, you’ve come to a good place. Dig-in, okay? Thank you for stopping-by. Bill

A test for bipolar disorder? Not exactly (but it helps).

Manic Depressive Symptoms

“I don’t know, sure seems like I have bipolar disorder. I mean, the symptoms I read about are a match. Why can’t there be a blood test?”

I know – were it that easy. But until a simple test can nail-down an emotional/mental health disorder diagnosis, we’re going to have to rely primarily upon signs and symptoms.

By the way, were you ever curious about the difference? It’s simple – signs are what the diagnosing clinician sees, symptoms are what you experience and (hopefully) report.

More clout? Symptoms.

Regarding the signs and symptoms of bipolar disorder (BD), the May 18 online edition of PLoS ONE features a study that suggests a new one.

Let’s get busy…

Postural Control and Bipolar Disorder?

Indiana University, Bloomington’s Amanda Bolbecker, PhD, and team, have come up with some interesting stuff…

Bipolar Disorder & Postural SwayOkay, it isn’t front page news – be it BD, unipolar depression, or the anxiety disorders – alterations of brain anatomy and physiology are factors. I always say this, but wouldn’t they have to be?

A few of the frequent flyers are the basal ganglia, cerebellum, and brain stem (pretend you see a stem hanging down to the left of the cerebellum). And this especially applies to BD.

Ready for more? The basal ganglia, cerebellum, and brain stem are also players in postural control.

Hmmm. Well,that got Dr. Bolbecker and her brain-trust a-thinkin’. Wouldn’t it at least make sense that postural control issues may be a characteristic of BD?

They wanted some answers. So they rounded-up 32 subjects, all age 38. 16 had BD (a portion on meds) and the others had no psych diagnoses.

What did they do with them? They asked them to stand as still as they could for two minutes on a force platform (measures ground reaction forces generated by a standing or moving body). And if that wasn’t enough, the subjects were asked to do so with their eyes open and closed.

Recorded and analyzed were postural sway changes, which are caused by muscle contractions involved in maintaining proper posture.

Postural sway is a reliable indicator of levels of dysfunction in the inter-workings of the basal ganglia, cerebellum, and brain stem.

Reduced Postural Control (and more)!

Well, wouldn’t you just know it. Ding, ding, ding – the BD subjects presented with sway results consistent with reduced postural control.

Furthermore, this was particularly the case when the BD subjects were asked to stand with their eyes closed – having no visual input.

That particular piece provided the research team with a bonus. It suggested that those with BD have deficits in sensorimotor integration and issues with making postural corrections.

Another possible explanation is the BD participants have a reduced ability to integrate and utilize proprioceptive information for motor control.

Proprioception is a very cool dynamic. It’s the sense of the relative position of neighboring parts of the body – the perception of the pain and movement of internal organs.

Here’s a link to a piece I wrote some time ago that’s a great fit here – Agoraphobia, Panic Attacks, Spatial Orientation: Perception is Everything.

Mood & Motor Disorders: Two Peas in a Pod?!

Though the relationship between the mood and motor disorders merits much more research – there’s definitely a fit. But that should be of no great surprise. The word emotion is based in the Latin, emovere – which roughly translates into movement.

More evidence? Think about Parkinson’s Disease. Isn’t depression a common feature? Okay, who wouldn’t be devastated by a Parkinson’s diagnosis. But the presenting depression is likely endogenous (of deeply internal origin), as opposed to situational.

The Take-Aways

It looks as though we’ve found yet another sign/symptom of bipolar disorder. And that really is a good thing for many reasons. How ’bout some take-aways…

  1. The detection of any sort of motor disorder may be of great assistance in confirming a diagnosis of bipolar disorder – and other mood situations.
  2. The relationship between the mood and motor disorders appears to be very real – and merits additional research.
  3. It seems as though the research community is stepping-up to the plate in terms of emotional/mental health work.

    i have been diagnosed with bp 1 for 10 years now, i have had 3 mania episodes where i have been sectioned in hospital . i started swaying side to side after the 2nd section cant remember which anti physcotic drug, i think it was abifily , the swaying did eventually stop because i stopped taking all meds but ended up back in hospital. this time they put me on risperdone and the swaying is back and as been for 3 years now! my shrink does not have a clue and dont really think he cares, just like my weight gain which is 6 stone in about 5 years. i dont sleep well either . he as just introduced another anti depressant to help with sleep along with 15mg of zopiclone, not helping still only get 4 hours. i am not high just normal to a bit low due to lack of sleep. this is the 1st i have seen something on swaying and bi polar, very interesting, and i will be mentioning this to my doc when i next see him , thanks helen uk

    • Well, thank you for participating, Helen. So glad I could present something so potentially helpful. Very curious as to your doc’s reaction/comments. Would you mind sharing?

    I am diagnosed with bipolar 2 and have a lot of trouble with balance, which I might look at as swaying. Interesting to get this information. Wish it would become a common test.

    • Thanks for visiting and contributing, npeden. Sweet that you found the info interesting. Hope you can somehow make it work for you! Knowledge will always be power…
