Research on the arts and outcomes related to Parkinson’s – and more related research and hypotheses

by

For our first article, we have a review on group based dance, singing, music, and theatrical treatments on a variety show of outcomes. 

A systematic review of active group-based dance, singing, music therapy and theatrical interventions for quality of life, functional communication, speech, motor function and cognitive status in people with Parkinson’s disease

Basically, they found that the arts seemed to have positive effects for folks with PD – but that not all types of arts were evaluated against all of the outcomes listed. So “More research is needed” to look into all aspects. But it’s a good thing.

Next up is a review of the effects of oxytocin and the effects of music on the human brain. And on social behavior and bonding. While not specifically directed at Parkinson’s disease, it is certainly applicable to treatments for people with Parkinson’s.

Links Between the Neurobiology of Oxytocin and Human Musicality

 It is argued that many of these characteristics of oxytocin biology closely mirror the diverse effects that music has on human cognition and emotion, providing a link to the important role music has played throughout human evolutionary history and helping to explain why music remains a special prosocial human asset. Finally, it is suggested that there is a potential synergy in combining oxytocin- and music-based strategies to improve general health and aid in the treatment of various neurological dysfunctions.

Keywords: oxytocin, music, dance, reward, empathy, trust, therapy

If there is a link between neurobiology and music, then it stands to reason that music played a part in the evolution of modern Homo sapiens. That is the topic of the brief review of:

Music and the Meeting of Human Minds by Alan Harvey

The author addresses

  1. when and why  modern humans evolved musical behaviors,
  2. the evolutionary relationship between music and language, and 
  3. why humans, perhaps unique among all living species, universally
    continue to possess two complementary but distinct communication streams.

He argues that “early in our history, the unique socializing and harmonizing power of music acted as an essential counterweight to the new and evolving sense of self, to an emerging sense of individuality and mortality that was linked to the development of an advanced cognitive capacity and articulate language capability.”

Dopamine is one of the keywords, so it should be of interest to People with Parkinson’s.

Another article along similar lines is Music as a coevolved system for social bonding,  The authors put forth an hypothesis and

make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding (MSB) hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music.

A review on dance and PD

by

Dance classes for Parkinson’s patients was one of the things that got me involved in Power for Parkinson’s© and the Georgetown Area Parkinson’s Support group to begin with. For me, it has helped to improve symptoms and quality of life tremendously.

In this desk review of many studies, the authors came to the following conclusions:

Overall, the reviewed evidence demonstrated that dance can improve motor impairments, specifically balance and motor symptom severity in individuals with mild to moderate PD, and that more research is needed to determine its effects on non-motor symptoms and QOL. RCTs that use a mixed-methods approach and include larger sample sizes will be beneficial in fully characterizing effects and in determining which program elements are most important in bringing about positive, clinically meaningful changes in people with PD.

 Carapellotti AM, Stevenson R, Doumas M (2020) The efficacy of dance for improving motor impairments, non-motor symptoms, and quality of life in Parkinson’s disease: A systematic review and meta-analysis. PLoS ONE 15(8): e0236820. https://doi.org/10.1371/journal.pone.0236820

I have come to the conclusion that every study or review has to include the phrase “more research is needed.” And it is true.

Oh, I’m walking to New Orleans… or maybe the Outback

by

Here’s a conference poster reporting some recent research on music and gait… and the effects of dual tasks on Parkinson’s Disease diagnosed people. It seems that all the researchers are in Australia, hence the title to this post.

Walkin’ and Talkin’: dual task effects on Gait

They had a few different tasks – just walking, walking while saying all the words one could think of starting with the letter (name a letter), and walking while counting in intervals. The conclusion was that Dance For Parkinson’s® had a positive effect. Naturally, they called for more research with larger numbers of participants.

In the meantime, as I always say: Don’t stop moving to the music!

Art, Dance, Medicine, Parkinson’s, Genetics, Oh My!

by

Arts and Medicine research – my only wish is that they would look into the possibility of physical changes in the brains of people involved, and not just on co-creating knowledge:

Co-creating knowledge…

Next:

Dance therapy demonstrates a highly appropriate choice of intervention to stimulate plasticity processes, improve age-related deterioration, and thus contribute to successful aging. Health care professionals involved in the care of elderly individuals should whenever possible consider the feasibility of associating dance therapy as a stimulating and therapeutic activity.

Dance therapy in aging: A systematic review

“There were 2,334 studies, out of which 6 were chosen.” This review limited itself to dance as therapy for healthy aging adults, and excluded those studies that looked at Parkinson’s or Alzheimer’s people. Again, I would hope that future studies look at changes in brain activity and structure, as well as observable differences in movement, etc.

Next, an open access article reviewing genetic risks involving Parkinson’s: “This study provides evidence that alleles associated with Parkinson disease risk, in particular GBA variants, also contribute to the heterogeneity of multiple motor and nonmotor aspects. Accounting for genetic variability will be a useful factor in understanding disease course and in minimizing heterogeneity in clinical trials.”

Genetic risk of Parkinson disease and progression: An analysis of 13 longitudinal cohorts

(Will have to read it in order to see what it says,  and compare it with my genome files to see what it means for me).

Progressively difficult or complex dance training is superior to repetitive physical exercise

by

Yep, you read that correctly. This research was done using neuro-imaging and revealed that brain plasticity ( how experiences reorganize neural pathways in the brain) is increased by a program of increasingly difficult dance training. (The title of this entry was edited 04/28/2021 to make it more clear that the variable was increasing the difficulty, and not simply dance vs. exercise. ALL exercise is good, as long as not overdone, but to incorporate research findings into the program (like Power for Parkinson’s or Lew-Ortiz Pabon’s Apollo Rhythm Club do), takes some extra effort).

Dance training is superior to repetitive physical exercise in inducing brain plasticity in the elderly.

… Both interventions increased physical fitness to the same extent. Pronounced differences were seen in the effects on brain volumes: Dancing compared to conventional fitness activity led to larger volume increases in more brain areas, including the cingulate cortex, insula, corpus callosum and sensorimotor cortex. Only dancing was associated with an increase in plasma BDNF levels. Regarding cognition, both groups improved in attention and spatial memory, but no significant group differences emerged. The latter finding may indicate that cognitive benefits may develop later and after structural brain changes have taken place. The present results recommend our challenging dance program as an effective measure to counteract detrimental effects of aging on the brain.

On a personal note, I noticed during a year long period of reduced mobility that my Parkinson’s symptoms had progressed (or regressed, depending on how you look at it). Slurred speech was perhaps one of the more obvious or noticeable symptoms. That has now disappeared, though one has to be mindful to speak clearly and loudly in order to be understood.

Physical exercise of any kind is good, it seems. Weight resistance and other exercises can benefit from the high intensity interval approach. But move to the music, and join a dance class that increasingly challenges the brain (especially if you are classified among the elderly, even if you are Young At Heart).

Put on your dancing shoes

by

Two links to Internet URLs reporting on recent research.

Comparing Dancing and Fitness

Dancing can reverse the signs of aging

The first link is the actual research article. The second link is an article reporting on the first one.

The results of the research article are not quite as effusive as the non-technical news article. Which is to be expected from a scientific article – don’t claim more than the data actually supports. The “popular ” press isn’t constrained by the same principles.

Bottom line – dance movement therapy is good for you. In my area, dance classes are free of charge and accommodate all levels of mobility, including wheelchair bound folks.

Dance, aerobic exercise and musical training

by

Today we have a couple of links to articles on the effects of dance and music:

Effects of Dance/Movement Training vs. Aerobic Exercise Training

Abstract only, but the results appear to be in favor of Dance Movement Therapy (DMT) as positive. Aerobic Exercise Therapy (AET) improved cardiovascular health, though, so both aerobic and dance movement therapies should be used for health.

Executive and non-executive composite scores showed a significant increase post-training (F(1,37)=4.35, p=.04; F(1,37)=7.01, p=.01). Cardiovascular fitness improvements were specific to the AET group (F(2,38)=16.40, p<.001) while mobility improvements were not group-dependent (10m walk: F(1,38)=11.67, p=.002; Timed up and go: F(1,38)=22.07, p<.001).
Results suggest that DMT may have a positive impact on cognition and physical functioning in older adults however further research is needed. This study could serve as a model for designing future RCTs with dance-related interventions.

Next, a short article on the effects of musical training on brain plasticity.

The-Effects-of-Musical-Training-on-Brain-Plasticity-and-Cognitive-Processes

The link between musical training and its effects on brain plasticity have been studied since the early 20thcentury neuroanatomy research of Ramon y Cajal. In recent decades, studies have observed the contributions of musical training in enhancing auditory, motor, and language processing areas of the brain. The ability of musical training to impact behavior and critical thinking skills may also open the door for new methods of combating age-and illness-related cognitive decline(emphasis added)

In conclusion, whether or not one has a neurodegenerative disease or not, it is good advice to do aerobic exercise for the heart, dance for the mobility, and learn or continue to play a musical instrument to keep the brain plastic and elastic and fantastic.

Dance and exercise – a study and a publications review

by

Not much new here – more evidence that dance exercises and physical exercise in general, is beneficial for people with PD.

Shall We Dance – master’s thesis  by Brittni Lynn McAlister, University of North Colorado

 In the words of one participant, the dance classes have been “. . . completely life-changing.”

Systematic review of exercises for Parkinson’s

This review revealed that people with Parkinson’s disease viewed physical activity as an enjoyable and positive experience, which aided with control of their symptoms and enhanced their wellbeing and quality of life.

Almost let these references get away

by

Some recent articles about music and dance – thought I had already published this – it appears not. Either that, or I’m more cognitively impaired than I thought I was. If this keeps up, I’ll have normal intelligence:

Dopamine, Oxytocin, Serotonin, and Endorphins 

Acronym is DOSE, and it’s a short article talking about how dance is good for you because it releases several different hormones and neurotransmitters – and not just because it makes you feel good – but because it does….😎

Language of music and psychophysical foundations  

from the abstract: “Application of music in rehabilitation medicine requires an understanding of the mechanisms of music perception. This article discusses differences in character of the basic melodic elements and addresses some of the specifics of tonal space. Colloquially, music is called the language of emotion. Bearing in mind that high-level cognitive functioning in humans is inseparable from affective consciousness, investigating the mechanisms of emotional processing belongs to an important area of cognitive sciences. Studying music perception can help to advance methods of music therapy and to elucidate major aspects of human consciousness.” (emphasis added)(Article is on ReseaechGate; membership(.

Drumming program to improve social interactions

Although the article is about subjects with autism spectrum disorder (ASD), I think that the results are likely to be replicable with or generalizable to Parkinson’s Disease folks.

” results suggest that the children with ASD significantly improved in the domains of enjoyment and fun, and showed a positive trend for developing improved social relationships with peers and camp counselor partners.”
