Strength training can help with PD symptoms

by

A review of studies indicates that strength training can help with mild to moderate Parkinson’s cases. (An earlier blog post here noted that a dance training program increased grey matter volume in the brain versus repetitive strength training. So don’t exclude either from your wellness program, is my [non-medical advice).

Review of strength training in people with Parkinson’s Disease

From the abstract:

Objective: To investigate the evidence on efficacy and limits of strength training in rehabilitation of Parkinson’s disease

Method:A comprehensive search on pubmed, clinical keys database using keywords Parkinson’s disease, physical therapy, strength training ,resistance training. The studies including Randomized controlled trails and systematic reviews published since 2005 are reviewed.

Results:36 studies identified through database searching. 25 studies are excluded due to duplicates, irrelevance, based on titles, outcome diversity. 5 systemic reviews and Meta analysis, 6 RCT are included. Review and analysis of articles is going on

Conclusion : The result of this review suggests that strength training program can be effective in people with mild and moderate parkinson’s disease. It can improve functional independency with increased muscle strength, gait parameters, posture and balance, all of these positive role on participation and quality of life

Kazoos are good for youse

by

All of the following links have to do with improving voice for PD folks, and also the use of kazoos.

I used to write for this student newspaper:

Music therapy helps tackle Parkinson’s (The Miami Hurricane July 5, 2019)

This is a fairly long honors project paper reviewing voice therapy techniques:

Voice Therapy Techniques in Combination with the Group Therapy Setting for Individuals withParkinson’s Disease

Not necessarily for PD, but the study used spectrographic analysis to measure the improvement in voice in addition to qualitative results.

Finger Kazoo: spectrographic acoustic modifications and vocal self-assessment

I might have already mentioned this in a previous entry, but kazoos were used:

Vocal warmups for the individual: Vocal warmups

Vocal warmups for the group: Anatomy of a choral warmup

I got rhythm, I got music…

by

Put together a slide presentation trying to synthesize some of the research on Parkinson’s Disease (PD) and the possibility of music, singing, playing musical instruments, and dance as means to counteract the progressive effects of dopaminergic neurons lost in the course of PD. Due to the length of the presentation and the limits of my computer resources, the narration seems to have gotten a little out of sync towards the end. But it is what it is, as they say: (note: added a PDF file of the presentation on 6-9-19 to make it easier to download and view)

Old drugs in new bottles

by

An interesting development, or in this case, two interesting developments, is the finding that currently available medications might be repurposed for their neuroprotective effects. Here are two articles on two drugs that show promise.

This is a report on a hypertension medication that provides neuroprotection in mice and may be transferable to humans… Are mice brains similar enough to humans for it to work? A recent report on isradipine, another hypertension medication, reported no differences in symptoms between controls and those receiving the medications. We shall see.

Felodipine induces autophagy in mouse brains with pharmacokinetics amenable to repurposing

Nrct we have a case in which a tricyclic antidepressant, nortriptyline, has been found to slow down the aggregation of alpha synuclein proteins in the brain.

Nortriptyline inhibits aggregation and neurotoxicity of alpha-synuclein

 Not sure whether either will pan out, but anyone with either hypertension or depression could discuss these articles with their doctor(s) and come to a mutually agreeable course of action.

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.

You are what you eat…

But before we get into the articles about the gut microbiome, from 2015, a review of the various signs that predate full motor symptoms

non-motor and pre-motor symptoms of PD

Recent studies provide new insights on the frequency, pathophysiology, and importance of non-motor features in Parkinson’s disease as well as the recognition that these non-motor symptoms occur in premotor, early, and later phases of Parkinson’s disease.

This study (2017) looks at the progression of PD and problems with the bacteria in the stomach:
Progression of PD and gut dysbiosis
from the conclusions:

The total counts of intestinal bacterial decrease in the course of PD progression. Temporal profiles of lowering of bacterial counts are likely to be different from bacteria to bacteria, and also between the deteriorating and stable groups, which may be able to be exploited to differentiate patients with rapidly and slowly progressive PD pathology.

The search for biomarkers for PD goes for the gut (2018):
Gut Microbiota Dysfunction as Reliable Non-invasive Early Diagnostic Biomarkers in the Pathophysiology of Parkinson’s Disease: A Critical Review

future directions should therefore, focus on the exploration of newer investigational techniques to identify these reliable early biomarkers and define the specific gut microbes that contribute to the development of Parkinson’s disease. This ultimately should pave the way to safer and novel therapeutic approaches that avoid the complications of the drugs delivered today to the brain of Parkinson’s disease patients.

Another article on the role of gut bacteria in PD (2018): Parkinson’s disease and bacteriophages as its overlooked contributors

Our findings add bacteriophages to the list of possible factors associated with the development of PD, suggesting that gut phagobiota composition may serve as a diagnostic tool as well as a target for therapeutic intervention, which should be confirmed in further studies. Our results open a discussion on the role of environmental phages and phagobiota composition in health and disease.

A review of the relationship between the gut microbiome and PD (2018):
Microbes Tickling Your Tummy: the Importance of the Gut-Brain Axis in Parkinson’s Disease

Looking back a few years, one can hope that diet might be a way to affect the course of PD, if diet can change the gut microbiome (2014) :Diet rapidly and reproducibly alters the human gut microbiome

Long-term diet influences the structure and activity of the trillions of microorganisms residing in the human gut1–5, but it remains unclear how rapidly and reproducibly the human gut microbiome responds to short-term macronutrient change. Here, we show that the short-term consumption of diets composed entirely of animal or plant products alters microbial community structure and overwhelms inter-individual differences in microbial gene expression.

A couple of abstracts on sleep and restless legs

by

Sleep quality as prodromal PD symptom

Although the above link only leads to an abstract, there is enough information to accept their conclusion that “in the general population, deterioration of sleep quality and duration are markers of the prodromal phase of parkinsonism, including Parkinson’s disease.”

Restless Legs Syndrome and whether or not it is improved by DBS is apparently not a matter of consensus RLS improved by DBS although, again, this is not a full text article.

Searching for the secret chord…

by

These came out of a search, so might have been previously covered in a post:

This review covers music performed in groups and is not directly related to Parkinson’s: Collaboration and improvisation

Music performance is inherently social. Most music is performed in groups, and even soloists are subject to influence from a (real or imagined) audience. It is also inherently creative. Performers are called upon to interpret notated music, improvise new musical material, adapt to unexpected playing conditions, and accommodate technical errors. The focus of this paper is how creativity is distributed across members of a music ensemble as they perform these tasks

This article does cover Parkinson’s – singing as a way to help with vocal issues and depression. Positive results, but not a randomized control type experiment, so conclusions are tentative:

Individualized singing program

Here’s an interesting experiment in which participants are asked to improvise music which reflects varied feeling states. Not sure how the results can be applied, except that creating music or dance/movement to express emotions is probably of benefit to the brains of people with Parkinson’s, regardless of the strength of the research.
Effects of music making

This study has gotten some wide distribution – on how musicians (people who play an instrument) react more quickly than people who do not. This article digest is from Science Daily (January 2017)

Play an instrument?

“fine” as they say on the sheet music.

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.”
