Sing!

by

What research has found its way into the email inbox recently?

Although singing is a nearly universal human behavior, many adults consider themselves poor singers and avoid singing based on self-assessment of pitch matching accuracy during singing (here referred to as singing accuracy), in contrast to the uninhibited singing exhibited by children. In this article, I report results that shed light on how singing accuracy changes across the lifespan, using data from a large online sample, including participants ranging from 6 to 99 years old. Results suggest that singing accuracy improves dramatically from childhood to young adulthood, unperturbed by voice changes during adolescence, and remain at a similarly high level for the remainder of life, exhibiting no strong tendency toward age-related decline. Vocal or instrumental musical training has significant positive effects on singing accuracy, particularly in childhood, though there was no evidence for gender differences. Finally, pitch discrimination varied with age similarly to singing accuracy, in support of views that singing accuracy reflects sensorimotor learning. Taken together, these results are consistent with the view that singing accuracy is a learned motor skill that benefits from engagement and can remain a fruitful endeavor into old age. (emphasis added).

Basically, this says that if you learned how sing accurately when you were young, you can probably sing well into your later years. And, since singing is a learned motor skill, one might assume that it can be learned even as one gets older.

Relevance to folks with Parkinson’s Disease (PD)?

Vocal strength exercises, such as those provided by Power for Parkinson’s as free YouTube video classes, can help with specific Parkinson’s related symptoms:

Many people with PD speak quietly and in one tone; they don’t convey much emotion. Sometimes speech sounds breathy or hoarse. People with Parkinson’s might slur words, mumble or trail off at the end of a sentence. Most people talk slowly, but some speak rapidly, even stuttering or stammering.

Parkinson’s motor symptoms, such as decreased facial expression, slowness and stooped posture, may add to speech problems. These can send incorrect non-verbal cues or impact the ability to show emotion. Source: https://www.michaeljfox.org/news/speech-swallowing-problems accessed June 20, 2022  (emphasis added).

Since our vocal cords are muscles, and singing is a learned motor skill, we can strengthen those muscles and push against the progressive, degenerative symptoms of PD through exercises that:

  • remind us to breathe deeply to sustain vocal volume,
  • improve our posture in order to enable deep breathing,
  • exercise the muscles of the face and mouth
  • to enable crisp diction instead of slurring and mumbling, and that
  • support emotional expression through inflection and singing.

And “Everybody Knows” that if exercise is fun, one is more likely to continue doing it.

Full disclosure: The author has attended Power for Parkinson’s ® vocal exercise classes since their inception in 2016, and co-founded a participant organized singing group (with the late Jeff Berke) in 2015.  Therefore, he might be (definitely is) biased in favor of this modality of treatment for vocal and speech related symptoms of PD.

We know what’s good for the “all” but we can’t say yet that we know what’s good for the “one.”

More evidence from experiments on mice on how and why exercise is good for People with Parkinson’s (PwPs):

The popularized article: Link between exercise and dopamine

And from the abstract and significance statement of the original (non-open access) article:

Physical exercise improves motor performance in individuals with Parkinson’s disease and elevates mood in those with depression. Although underlying factors have not been identified, clues arise from previous studies showing a link between cognitive benefits of exercise and increases in brain-derived neurotrophic factor (BDNF). (emphasis added).

and:

Exercise has been shown to improve movement and cognition in humans and rodents. Here, we report that voluntary exercise over 30 days leads to an increase in evoked dopamine (DA) release throughout the striatum, and an increase in BDNF in the dorsal (motor) striatum. The increase in DA release appears to require BDNF, indicated by the absence of DA release enhancement with running in BDNF+/- mice. Activation of BDNF receptors using a pharmacological agonist was also shown to boost DA release. Together these data support a necessary and sufficient role for BDNF in exercise-enhanced DA release, and provide mechanistic insight into the reported benefits of exercise in individuals with dopamine-linked neuropsychiatric disorders, including Parkinson’s disease and depression. (emphasis added).

The citation:

So that covers why exercise is good for all. But what about what is good for the one?

… there is growing recognition that PD is not a single entity but instead reflects multiple diseases, in which different combinations of environmental, genetic and potential comorbid factors interact to direct individual disease trajectories… The clear consequence of there being distinct diseases that collectively form PD, is that there is no single biomarker or treatment for PD development or progression. We propose that diagnosis should shift away from the clinical definitions, towards biologically defined diseases that collectively form PD, to enable informative patient stratification. N-of-one type, clinical designs offer an unbiased, and agnostic approach to re-defining PD in terms of a group of many individual diseases. . (emphasis added).

The citation links to PubMed where you can download the full article, should you be so inclined. The next citation also links to an open access free article.

In this article, Riggare reports on self tracking done in 2012 (as a Person with Parkinson’s), and the offer the possibility that self-tracking of symptoms and medications can help to inform the physician’s decisions over the course of treatment. In other words, one should be a self-advocate as a patient and work with your physician to achieve the best combination of treatments to address Parkinson’s and its comorbidities. (At least that’s my takeaway from the article. Others might differ).

Another look at PD aims to categorize it into various sub-types:

This article is a “desk review”of other studies, using specific criteria to either include/exclude each study in the results. Their conclusion: 

Conclusion: Subtyping studies undertaken to date have significant methodologic shortcomings and most have questionable clinical applicability and unknown biological relevance. The clinical and biological signature of PD may be unique to the individual, rendering PD resistant to meaningful cluster solutions. New approaches that acknowledge the individual-level heterogeneity and that are more aligned with personalized medicine are needed. (emphasis added).

Among the articles cited in the bibliography is this one (another open access article):

In this, the authors describe their methodology and results from the Oxford cohort (one of several cohorts of PwPs and controls that have been used for research. (I would take the time and effort to locate the original publication describing the different cohorts involved in the effort to find biomarkers, but I am currently experiencing a wave of Parkinson’s related apathy. Check my past posts, or do a search on PubMed – I do remember that Oxford and Boston were two of the cohorts of PwPs.  But I digress).

Results: Apolipoprotein A1 and C-reactive protein levels differed across our PD subtypes, with severe motor disease phenotype, poor psychological well-being, and poor sleep subtype having reduced apolipoprotein A1 and higher C-reactive protein levels. Reduced apolipoprotein A1, higher C-reactive protein, and reduced vitamin D were associated with worse baseline activities of daily living (MDS-UPDRS II).

Conclusion: Baseline clinical subtyping identified a pro-inflammatory biomarker profile significantly associated with a severe motor/nonmotor disease phenotype, lending biological validity to subtyping approaches. No blood biomarker predicted motor or nonmotor prognosis. © 2019 The Authors.

In other words: Close, but no cigar. But I, for one, certainly could have benefited from this knowledge had it been available 60 years ago. (don’t get me started – I’ve played that tape many times before).

Oh well, let’s end on a high note:

Participants needed for Narrative Study in Parkinson’s Disease – study starts February 26, 2022

by
Robert Cochrane is recruiting participants for a new Parkinson’s Disease study. See below. Note the three categories of PD people needed:
” We are recruiting male and female persons diagnosed with idiopathic (unknown cause) Parkinson’s disease between and fit ONE of the following criteria:
– They have been diagnosed within the last year,
– are early onset (diagnosed before the age of 50)
– are active or former members of the U.S. military. “”
Here’s the full recruitment flyer:
Participants needed for Narrative Study in Parkinson’s Disease Principal Investigator, Dr. Gabriele Wulf, and Robert Cochrane, PhD student at UNLV, are looking for persons with Parkinson’s disease to participate in an online research study of heroic narrative upon Parkinson’s disease. Study participants will be asked to share their perceptions and experiences about Parkinson’s from the time they were diagnosed to today, and how they feel about their future quality of life expectations. They will be taught heroic storytelling structure and practical tools of how to explore and incorporate it into their own lives. Heroic storytelling is based on the works of Joseph Campbell’s monomyth. Campbell’s work is broken into a 12-step journey for this class that participants will follow and use to write their own heroic journey with Parkinson’s disease. Participation in this study will require completion of 12 sessions, meeting once a week on Saturday mornings from 9a-10:30a (Pacific Time). Participants Will also be required to write a one-page personal assessment each week outside of class. Finally,online surveys at the beginning, middle and end of the 12-session period will be required. All sessions will take place online via Zoom. All sessions will be recorded. Participants must have a WiFi enabled device in a safe location (e.g. participants’ home) for these sessions. Sessions will include writing, theatrical improvisation and lectures from guest subject matter experts in fields such as dance, art and mythology. We are recruiting male and female persons diagnosed with idiopathic (unknown cause) Parkinson’s disease between and fit ONE of the following criteria:
– They have been diagnosed within the last year,
– are early onset (diagnosed before the age of 50)
– are active or former members of the U.S. military. Participants must be between 1-3 on the Hoehn and Yahr scale. This assessment should be given by participants’ neurologist or movement disorder specialist prior to acceptance into the program. We cannot accept persons who have an inability to communicate verbally, are uncomfortable writing, or are unable using the Zoom platform. Please email Robert Cochrane at cochra58@unlv.nevada.edu with questions or to express your interest in participating.This program was made possible, in part, by a grant from the Parkinson’s Foundation. Thank you!

Keep on moving to (and making) music

by

The evidence that rhythm, movement, and making music continues to accumulate as a therapeutic approach to address the symptoms and Quality of Life issues related to Parkinson’s Disease (PD).

Today we look at an article just out in Frontiers of Human Neuroscience, titled

Rhythm and Music-Based Interventions in Motor Rehabilitation: Current Evidence and Future Perspectives  

Over the last quarter of a century, increasing research results point to rhythm and music as effective and useful tools for treatment and rehabilitation of people with neurological disorders. This article reviews the evidence for four different approaches, what the consensus is at the present time, and, of course, suggests future directions.

The authors look at four different approaches:

  1. Rhythmic Auditory Stimulation (RAS)
  2. Music-Supported Therapy (MST)
  3. Therapeutic Instrumental Music Performance therapy (TIMP) and
  4. Patterned Sensory Enhancement (PSE)

The consensus of recent meta-analyses and systematic reviews is that, for Parkinson’s Disease (PD), is that RAS is an effective tool for improving gait, stride, and speed – folks walk faster and with longer steps with RAS. Additionally, evidence is showing that it also reduces freezing of gait (FOG), improves balance and reduces the occurrence of falls.

Neither MST nor TIMP have been studied much beyond the rehabilitation of stroke patients. They involve practicing on a keyboard or drums, beginning with the patient’s comfort level and increasing in difficulty. Some studies have begun to be used to investigate effectiveness as treatments for PD.  Some have shown improvements in motor dexterity. More research is needed, but in the meantime, learning to play drums or keyboards can’t hurt, and may enrich one’s quality of life (QOL).

Growing evidence in neurological and brain imaging have shown increased activity in the auditory and motor areas of the brain, indicating that brain plasticity might be achieved through music and rhythmic interventions. The authors note that RAS has been well studied with stroke and PD populations, but not with other movement disorders and Alzheimer’s populations. In addition MST and TIMP have only begun to be investigated as a means of restoring fine motor coordination.

The authors also call for neuroimaging use in studies, to better understand the physiological basis of the rehabilitation process. They point out the gaps in research and hope to provide a framework for future research – not so much a roadmap, I would think, but a laying out of what we know and what we don’t know, and what kinds of studies are needed to answer the questions about what we don’t know..  They state that “musical rhythm is a powerful tool” for therapy, and our understanding and exploration of how it modulates brain networks is in the initial stages.

 In other words, “We’ve only just begun.”

Meanwhile: Don’t stop moving to the music.

RBD and other things PD-related

by

Diagnosis of PD is often not made until a person is in their 60s. With all the attention that has been focused on the disease(s) in the last 20 years or so, I suspect that more people are getting diagnosed at an earlier age, although most cases of young onset PD are likely to be genetic in origin.

However, an “early” diagnosis may not be a timely diagnosis, as  the title of one opinion piece I read some time ago said (see link below).

It is now becoming apparent that “Parkinson’s”includes several categories of symptoms, not just rigidity, tremors, and gait, as shown in the table below::

Source for the following table, accessed 11/28/2021:  URL=https://www.frontiersin.org/article/10.3389/fneur.2020.00686

The problem is that treatment and diagnosis are often delayed until PD has already reduced Quality of Life for many folks.

Good evidence for the quality-of-life benefits of existing symptomatic treatment supports the argument for earlier diagnosis at a time when symptoms are already present (emphasis added). This argument would be significantly bolstered by the development of disease-modifying treatments. Benefits of early diagnosis and treatment would affect not only the individual (and their families) but also the wider society and the research community. Ultimately, however, shared decision-making and the principles of autonomy, beneficence, and non-maleficence will need to be applied on an individual basis when considering a “timely” diagnosis.

Therefore, the earlier one can predict the probability or inevitability of PD the sooner one can use treatments – whether pharmacological, surgical, nutritional, or lifestyle in nature – that can either reduce, delay, or defer (and possibly reverse?) the symptoms of PD.

Of all the symptoms associated with PD: tremors, bradykinesia, depression & anxiety, posture, gait issues (difficulties walking), REM Sleep Behavior Disorder (RBD), anosmia (loss of ability to smell), cognitive issues, facial masking, and micrographia (small handwriting) – RBD is the one which is most highly predictive of a later PD diagnosis.

The predictive ‘specificity’ is so strong that if someone has RBD, the chance of being diagnosed with Parkinson’s or related conditions over the next 15 years or more is over 80%

If an 18-21 year old person walked into a physician’s office with RBD, essential tremors, and depression as main symptoms, what would happen? In 1970, probably nothing – one might get treated for depression, but essential tremors are also called “benign”tremors, and were ignored, even if the patient reported being able to feel the tremors while resting, though invisible to the external observer. As for RBD, it would probably also be ignored.

By “a physician,” we are talking about a General Practitioner, or “family doctor,” and not s specialist like a  Movement Disorders Specialist who would be trained to identify varied symptoms, including those that are prodromal. And, of course, the identification of prodromal symptoms has only been investigated within the last decade or so, and are identified as for “research only” purposes – not for clinical diagnosis. A recent survey article (not referenced below) indicated that a majority of general practitioners were either unaware of the Movement Disorders Society’s list of prodromal symptoms, or were not using them to make referrals to Movement Disorders Specialists.

But thanks to the dedication and generosity of folks like Michael J. Fox and others, PD has become a respectable disease for which the person who has it has no reason to be apologetic or ashamed, and can hold their head up (and they ought to, since one symptom is to walk with shoulders stooped down) and proudly proclaim that they have Parkinson’s, which is why they walk funny. And so it goes.

Late Stage Parkinson’s (LSP): Undertreated?

by

This paper (or rather a chapter in a thesis) landed in my newsfeed recently. In it, the authors describe a study done to see whether people with Parkinson’s in the later stages are getting adequate treatment and whether they could benefit from more specific treatment. (A link to the PDf file is at the end of this post).

A person in Late Stage Parkinson’s has more than one of the following:

  • Motor symptoms not controlled despite medication.
  • Levadopa-related dyskinesias or dystonia,
  • PD dementia (defined according to MDS Task Force definition (Dubois et al. 2007), and
    not treated with cholinesterase inhibitors,
  • Depression not adequately treated,
  • Neuropsychiatric symptoms, such as agitation/ aggression; anxiety and irritability,
  • Orthostatic hypotension, pain, constipation, urinary symptoms, insomnia or daytime sleepiness (autonomic systems degeneration),
  • Falls on a regular basis,
  • Other symptoms related to risk of choking, speech issues, or producing too much saliva,
  • Inadequate Home environment.

Basically, the study provided a list of recommended activities and treatment on a sheet of paper (the control group) and actually providing the treatments and activities recommended, (the treatment group).

Not surprisingly, the treatment group did better at the end of the study than the controls. The conclusions were that people in late-stage Parkinson’s are often undertreated and could benefit from implementation of movement disorder specialists’ recommendations. (One would hope that the control group would also be provided with the treatments after the study ended. Perhaps, leading to another report)?

I’ve paraphrased the table used to describe late stage Parkinsonism in order not to infringe on their copyright. The title of the entire thesis is “Impairment and Disability in Late Stage Parkinsonism” and the overall author is Danny Hommel. I couldn’t find an email to ask for permission in writing to reproduce anything verbatim.

Other chapters include:

  • The late-stage of parkinsonism’s – motor and non-motor complications
  • The prevalence and determinants of neuropsychiatric symptoms in late-stage parkinsonism
  • Prevalence and prescribed treatments of orthostatic hypotension in institutionalized peoples with Parkinson’s disease (the chapter discussed in this post)
  • Optimizing treatment in undertreated late-stage parkinsonism: a pragmatic randomized trial
  • General discussion/English summary

Not a cure, but a biomarker

by

A biomarker for Parkinson’s?  Maybe… (If you don’t have a free ResearchGate account, yu might not be able t see this link):

A blood marker for Parkinson’s Disease: Neuronal exosome-derived α-synuclein

This isn’t in print yet, so I’ll just quote frm the abstract:

18 To date, no reliable clinically applicable biomarker has been established for Parkinson’s
19 disease (PD). Our results indicate that a long hoped blood test for Parkinson’s disease may
20 be realized. We here assess the potential of pathological α-synuclein originating from
21 neuron-derived exosomes from blood plasma as a possible biomarker. Following the
22 isolation of neuron-derived exosomes from plasma of PD patients and non-PD individuals
23 immunoblot analyses were performed to detect exosomal α-synuclein. Under native
24 conditions significantly increased signals of disease-associated α-synuclein forms in neuron25 derived exosomes were measured in all individuals with PD and clearly distinguished PD
26 samples from controls. By performing a protein misfolding cyclic amplification assay these
27 aggregates could be amplified and seeding could be demonstrated. Moreover, the
28 aggregates exhibited β-sheet-rich structures and showed a fibrillary appearance. Our study
29 demonstrates that the detection of pathological α-synuclein conformers from neuron-derived
30 exosomes from plasma samples has the potential of a promising blood-biomarker of PD.

Exosomes are small bundles of proteins  enclosed by a membrane (if I understand it correctly)(feel free to correct me- the Wikipedia article hd a note saying that it was too technical for most readers – and I agree).

Exosomes contain material from the cells from which they originated, so might be used as biomarkers. Obviously, it will take a while to fund the research and develop some way to determine how far along the way to developing PD someone is.  But the sooner a person can deal with it, the better the opportunity to live well with it. I look forward to the development of biomarkers that will help predict who might get Parkinson’s, so those folks can take preventive action.

I am fortunate that my symptoms did not appear in the usual sequence,and that I had DBS early after diagnosis, have had an outstanding medical team looking out for me and working with me, have a strong local community supporting people with Parkinson’s, and have a care partner who makes sure that my diet is full of organic foods, produce, and as few highly processed foods as possible. And I get lots of exercise, considering that I’m not athletic and I am not into weightlifting or bodybuilding.

Lucky me.

This is photography on Parkinson’s

by

This is photography on Parkinson’s… sometimes. Sometimes you accidentally hit the button due to herky-jerky movements, sometimes you manage to get the shot you envisioned in the viewfinder. Some days your vision is blurred and it’s hard to say whether or not you have the item you want in focus, in focus. More often than not, it’s blurred, and the background or foreground isn’t focused instead. Of course, one can always use autofocus, but that has the same issues as manual focus with blurry vision. The best one can do in that situation is to click the shutter as soon as the screen blinks red, indicating that everything’s in focus. And then, of course, somedays you get the focus right and the shutter speed and it all works. Then again, when life hands you bitter citrus, sometimes you can make a Margarita. Or better yet, KeyLime Pie.

Depression, Parkinson’s Disease, Cannabis, suicidal ideation, and more…

by

There are two types of depression, we are sometimes told: Depression, and bipolar disorder. To my way of thinking, at least, ALL depressions are bipolar in nature. It’s just that those who don’t have the wild swings of high to low, but just from “normal” to low, aren’t considered to be be bipolar. (The report on Cannabis and suicide doesn’t mention PD, but it seemed close enough to the topic of depression that I included it.

But what do I know? I’m not a trained psychiatrist or psychologist.Here’s some articles from some folks who seem to have expertise in the area:

First: find out whether someone with PD is depressed.

Williams JR, Hirsch ES, Anderson K, Bush AL, Goldstein SR, Grill S, Lehmann S, Little JT, Margolis RL, Palanci J, Pontone G, Weiss H, Rabins P, Marsh L. A comparison of nine scales to detect depression in Parkinson disease: which scale to use? Neurology. 2012 Mar 27;78(13):998-1006. doi: 10.1212/WNL.0b013e31824d587f. Epub 2012 Mar 14. PMID: 22422897; PMCID: PMC3310315.

Conclusions: The Geriatric Depression scale (GDS-30) may be the most efficient depression screening scale to use in PD because of its brevity, favorable psychometric properties, and lack of copyright protection. However, all scales studied, except for the UPDRS Depression, are valid screening tools when PD-specific cutoff scores are used. (emphasis added).

And guess what? Comorbidities need to be considered, and depression rating scales don’t really tease out one of the more common ones. 

Calleo J, Williams JR, Amspoker AB, Swearingen L, Hirsch ES, Anderson K, Goldstein SR, Grill S, Lehmann S, Little JT, Margolis RL, Palanci J, Pontone GM, Weiss H, Rabins P, Marsh L. Application of depression rating scales in patients with Parkinson’s disease with and without co-Occurring anxiety. J Parkinsons Dis. 2013;3(4):603-8. doi: 10.3233/JPD-130264. PMID: 24275604.

Conclusions: Co-occurring anxiety disorders do not impact performance of depression rating scales in depressed PD patients. However, depression rating scales do not adequately identify anxiety disturbances alone or in patients with depression.

Why should we care? Because depression has an adverse effect on daily living for those with PD.

Pontone GM, Bakker CC, Chen S, Mari Z, Marsh L, Rabins PV, Williams JR, Bassett SS. The longitudinal impact of depression on disability in Parkinson disease. Int J Geriatr Psychiatry. 2016 May;31(5):458-65. doi: 10.1002/gps.4350. Epub 2015 Aug 18. PMID: 26284815; PMCID: PMC6445642.

Objective: Depression in Parkinson disease (PD) is a common problem that worsens quality of life and causes disability. However, little is known about the longitudinal impact of depression on disability in PD. This study examined the association between disability and DSM-IV-TR depression status across six years.

Results: A total of 43 participants were depressed at baseline compared to 94 without depression. Depressed participants were more likely to be female, were less educated, were less likely to take dopamine agonists, and more likely to have motor fluctuations. Controlling for these variables, symptomatic depression predicted greater disability compared to both never depressed (p = 0.0133) and remitted depression (p = 0.0009). Disability associated with symptomatic depression at baseline was greater over the entire six-year period compared to participants with remitted depressive episodes or who were never depressed.

Conclusions: Persisting depression is associated with a long-term adverse impact on daily functioning in PD. Adequate treatment or spontaneous remission of depression improves ADL function. (emphasis added).

Teamwork is needed. If the person with PD can’t be their own advocate, then someone needs to help coordinate and communicate.

Abstract

Although Parkinson disease (PD) is defined clinically by its motor symptoms, it is increasingly recognized that much of the disability and worsened quality of life experienced by patients with PD is attributable to psychiatric symptoms. The authors describe a model of multidisciplinary care that enables these symptoms to be effectively managed. They describe neuropsychiatric complications of PD itself and pharmacologic and neurostimulation treatments for parkinsonian motor symptoms and discuss the management of these complications. Specifically, they describe the clinical associations between motor fluctuations and anxiety and depressive symptoms, the compulsive overuse of dopaminergic medications prescribed for motor symptoms (the dopamine dysregulation syndrome), and neuropsychiatric complications of these medications, including impulse control disorders, psychosis, and manic syndromes. Optimal management of these problems requires close collaboration across disciplines because of the potential for interactions among the pathophysiologic process of PD, motor symptoms, dopaminergic drugs, and psychiatric symptoms. The authors emphasize how their model of multidisciplinary care facilitates close collaboration among psychiatrists, other mental health professionals, neurologists, and functional neurosurgeons and how this facilitates effective care for patients who develop the specific neuropsychiatric complications discussed.

An analysis of survey data from more than 280,000 young adults ages 18-35 showed that cannabis (marijuana) use was associated with increased risks of thoughts of suicide (suicidal ideation), suicide plan, and suicide attempt. These associations remained regardless of whether someone was also experiencing depression, and the risks were greater for women than for men. The study published online today in JAMA Network Open and was conducted by researchers at the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.

“While we cannot establish that cannabis use caused the increased suicidality we observed in this study, these associations warrant further research, especially given the great burden of suicide on young adults,” said NIDA Director Nora Volkow, M.D., senior author of this study. “As we better understand the relationship between cannabis use, depression, and suicidality, clinicians will be able to provide better guidance and care to patients.”

On the other hand, it could be that young adults are depressed or suicidal because they live in a world in which constant war is being fought, in which war profiteering is not a crime, in which they see politics reduced not to a game of collaboration and mutual benefit, but a zero sum game in which the winner takes all. Perhaps they are depressed over the failure of the governments to address the mounting scientific evidence that climate “change” is resulting in climate chaos, and yet the governments of the world, funded by the fossil fuel industries, are “rearranging deck chairs on the Titanic” while the media band plays on. I could go on, but I won’t.

I used to be suicidal, but my life has changed. 

More to the point:

The National Suicide Prevention Lifeline is available today, providing suicide prevention and mental health crisis assistance at 1-800-273-8255 and through online chats. 988 is not a nationwide calling code right now. The Veterans Crisis Line is available today, providing Veteran specific suicide prevention and crisis assistance at 1 800 273 8255 (Press 1), by texting 838255, and through online chats at veteranscrisisline.net. On July 16, 2020, the FCC adopted rules to establish 988 as the new, nationwide, easy-to-remember 3-digit phone number for Americans in crisis to connect with suicide prevention and mental health crisis counselors.

And a final note: one of the main defenses against depression is activity is physical activity and human or non-human interaction. So get out here and run a mile, walk along a nature trail, play some music, call a friend, join a group or club, hug a tree, kiss a girl/boy, and get connected with the world we live in. 

You’ll feel better if you do.

What to do?

by

When it comes to diseases like cancer, the UK medical folks have decided that the “fighting” and “warrior” mentality are counter-productive. For one, this mindset causes people to delay seeking treatment. I don’t have the exact citation at hand, but it is referenced in this blog somewhere, and you’re welcome to search for it. (Thankfully, this is not a dissertation or scholarly article, or I couldn’t have written the previous sentence and gotten away with it).

But when it comes to exercise as a good way to slow, and sometimes reverse the physical or cognitive symptoms of Parkinson’s Disease (PD), there ain’t no doubt in some folks minds that dance is one of the finer things around to combine aerobic exercise, movements, and cognitive challenges to build new connections between neurons in the brain.

From the Digital Commons at Sarah Lawrence College comes this Master’s Thesis:

Rajan, Sneha, “Embodied Medicine: Integrating Dance/Movement Therapy into Physical Medicine & Rehabilitation” (2021). Dance/Movement Therapy Theses. 79. https://digitalcommons.slc.edu/dmt_etd/79

Long story short: “Overall, physiatry and dance/movement therapy have separately helped so many people but developing a synergy between these fields has the potential to transform rehabilitative medicine.”(emphasis added).

Specifically addressing Parkinson’s Disease issues, she writes:

For individuals with Parkinson’s disease, studies have shown that physical rehabilitation is an effective way to manage motor and non-motor symptoms (Mitra et al., 2020). However, maintaining motivation for treatment is difficult because of progressive difficulties with physical disability and co-existing emotional factors, so as a result not many adults engage with enough physical exercise (Mitra et al., 2020). By incorporating cognitive, emotional, and social components, the exercise environment could become more engaging and multidimensional (Mitra et al., 2020). One experimental study examined the effects of dance/movement therapy sessions on the cognition, quality of life, and motor symptoms of patients with Parkinson’s disease (Mitra et al., 2020). They used a variety of techniques such as targeted body exercises, memory games, movement improvisation, guided imagery, rhythm work, contact improvisation, mirroring, body coordination and movement reflexes (Mitra et al., 2020). Music was also used to incorporate rhythm and sensory motor cues (Mitra et al., 2020).

As a result, participants showed a significant increase in cognitive functioning and a decrease in Parkinson’s related health difficulties. Additionally, patients reported improvements in coordination, mood, and memory (Mitra et al., 2020). Another study analyzed the effectiveness of music-based movement therapy on gait related activities in Parkinson’s patients (Dreu et al., 2011). They examined both individual music-based gait training and partnered-dance interventions. The music provides rhythmic cues that help synchronize movements and also facilitates emotional responses in the participants (Dreu et al., 2011). Participants showed improvements in walking velocity and balance (Dreu et al., 2011). (Emphasis added.)

 If I were to judge this Master’s thesis, I would suggest more sources, and more recent ones than the one she used in material about Parkinson’s in the paragraphs before the ones I quoted above. But I’m not on the faculty of Sarah Lawrence College, so that’s their loss.

And the answer to the question posed in the title of this blog entry “What to do?” is simple: Don’t Stop Moving To The Music!
