self-portraits with alzheimer’s disease

I went to an interesting talk last week, titled “a dialogue on aging, developmental disabilities and dementia” and learned a lot about how dementia impacts older persons with intellectual and developmental disabilities.
… Like how older persons (>40yrs) with down-syndrome are at a high risk (25%+) for developing Alzheimer’s disease. And the implications of that on health services, aging parent caregivers and housing.
Another interesting piece I took away was about the artist William Utermohlen.
William was an American artist who died of complications from Alzheimer’s disease in 2007. His work expresses his experience as a patient living with this disease.
As his disease progressed, William focused on self-portraiture, particularly his own head and strange, black, half-open doorways which started to appear in the background. His declining movement control over his movement forced him to switch from oils to watercolours and pencils. I was really taken by his work; it is a fascinating insight into the mind of a person with Alzheimer’s. much love.

promising biomarker for parkinson’s disease: PPMI results

Parkinson’s disease is typically characterized in a clinical setting by the present of tremor, rigidity, bradykinesia (slow movement), and in the later stages, postural instability (balance).

Researchers from the University of Pennsylvania report ( JAMA Neurology) that the appearance of proteins in the spinal fluid may be the key to identifying affected patients early in the disease process, long before symptoms set in. The study results, which came from the Parkinson’s Progression Markers Initiative (PPMI) study. PPMI is sponsored by the Michael J Fox Foundation and aims to take biological measurements from 400 patients and 200 healthy controls to better understand the onset and progression of the disease.

The study found that people with early stage Parkinson’s had lower levels of the biomarker proteins amyloid beta and alpha synuclein.

It also distinguished between people with different disease presentations:

  • those with higher levels of motor dysfunction,  had lower levels of tau and alpha synuclein,
  • those whose muscles tended to freeze, or people who had difficulty walking, showed lower levels of amyloid beta and tau.

These promising results suggest we may be able to detect Parkinson’s with spinal fluid earlier, which could change the way it is diagnosed and treated. It also suggests for the first time that there may be different types of the disease with different potential treatments. This seems to support the hypothesis that Parkinson’s disease is a “spectrum”, and that people are diagnosed and face different disease along the “dopamine spectrum”.

This is definitely a step in the right direction. Having a biomarker to enable earlier detection and better disease management will improve the quality of life of all those involved. Really exciting! much love.

stem cells : recent updates on brain cell connections

this summer, some great stem cell research with implications for Parkinson’s disease came out of the Centre for Brain Research Centre at Aukland University, New Zealand.

in the brain, a slippery coating (polysiatic acid) on brain cells enable them to move easily to their destination, connect with other brain cells and turn into neurons. once they reach their target, the slippery coating is removed and the cell gets locked in place.

researchers have found that in neurodegenerative diseases, like Parkinson’s disease and Alzheimer’s disease, there is an oversupply of insulin that blocks the process of removing the slippery coating. They are currently working on drugs that will act to increase the amount of reabsorption to help brain cells re-connect with each other. This is a clue to the decrease in brain plasticity seen in neurodegenerative diseases.

The study results were published online in July’s  ‘ahead of print’ version of The Journal of Neurochemistry. ‘Insulin and IGF1 modulate PSA-NCAM turnover in a process involving specific extracellular matrix components’, by Hector J. Monzo, Thomas I. H. Park, Birger Victor Dieriks, Deidre Jansson, Richard L. M. Faull, Mike Dragunow, Maurice A. Curtis.

some really exciting findings that will contribute to the development of possible disease modifying treatments for neurodegenerative diseases! much love.

(more) professional athletes with Parkinson’s… an ongoing discussion

Something that keeps showing up in the news.
Former professional athletes (from all arenas) coming out with Parkinson’s diagnoses…
Steve Ludzik (NHL)
Dave Parker (MLB)
Brian Grant (NBA)
Forrest Gregg (NFL)
… is it the repeat blows to the head leading to Brain Injury (see post HERE)if so, how do we make these games safer (concussion-wise), while still retaining the spirit of the sport? How does this apply to other “hard hitting” jobs, like military?
just something that has been on my mind… much love.
Interested in more? here’s a start… Lehman et al. Neurology Sept 2012
and have you seen this documentary “Head Games” (2012)

my favourite APPS: National Parkinson Foundation

Have you seen National Parkinson Foundation‘s new app?

It’s a really comprehensive app designed to provide information on symptoms, both motor and non-motor (they have a great section on depression), current research, treatments and where to go for more resources and support!

You can access the app HERE, or follow National Parkinson Foundation on twitter or facebook! Check it out, what do you think? much love

thoughts about genetic testing

“I’ve got the gene for …”

Have you thought about genetic testing? Thought about finding out what might be in store for you? Would finding out something change the decisions you make? Change how you live your life?

Would knowing empower you or cripple you by casting a shadow over the rest of your life?


A “family decision”?

… because it’s not only about you. Testing yourself means testing your family; “Don’t you see? If your test is positive, it means I’ve got the gene, too. And I don’t want to know. I have a right not to know, don’t I?”

This genetic knowledge is also most likely to have a great impact on the choices to be made by those who are contemplating parenthood. Could decisions around fertility, and advanced in-vitro fertilization techniques, like preimplantation genetic diagnosis, “prune” genetic diseases from a family tree?

Diagnosis vs. Treatment.

These are the issues we face as scientists learn more about genetics…. the balance between knowing and not. What should be do with all this new information? Especially when genetic disease prediction continues to outpace medicine’s ability to treat or cure. For example, we have a genetic test for Huntington’s disease that can confirm a mutation, but it offers no treatment for the devastating symptoms. This leads to a therapeutic rift between what we know and what we can do.

Legal issues.

What about socially and/or legally? What if the results might become public and cause exclusion from employers or insurers. Laws to prohibit discrimination of people with a history of genetic disorders are not yet completely in place.

Margaret R. McLean, director of Biotechnology and Health Care Ethics at the Markkula Center for Applied Ethics, offers the following questions to clarify some of the key issues facing medical genetics in the years to come;

1. What is the purpose of taking a particular genetic test? Who is affected by the results?

2. Who has control of genetic information?

3. What does it mean to offer genetic testing and/or therapy in the absence of universal access to health care?

4. On what basis should someone undertake genetic intervention such as genetic constructive surgery if and when it becomes available?

5. For what kind of genetic future are we planning?

… or improved resources?

… or can it lead to a wealth of research resources, like the story of 23 and me’s Anne Wojcicki and her husband (google founder) Sergei Brin. “Brin, who began donating to Parkinson’s research in 2005, accelerated that giving after he learned in 2008 he has a flawed gene (LRRK2) that presents him with a 50 percent chance of getting the disease by age 70. So far Brin has donated $132 million, mostly through the Michael J. Fox Foundation for Parkinson’s Research, to help create a DNA database of 7,000 patients and to support work on the first targeted treatments that aim at the genetic causes of the movement disorder.” (source)

Have you had genetic testing? Have you thought about it? What is most attractive about genetic testing to you? What is the biggest barrier? Please share your thought’s in the comments below! much love.

Dance for Parkinon’s: IRISH

So, we’ve talked about TANGO, and about BALLET … but now, IRISH!


Researchers at both the St. Raffaele Arcangelo Hospital in Venice, Italy and University of Limerick  are finding that following 8-weeks of twice weekly Irish dance classes, persons with Parkinson’s fell less often and were more mobile. They speculate the benefits are attributed to the exercise, strong rhythm of Irish music and the sociability of group dances.

The steady rhythm provided by the music (in this case, Irish Folk) acts as an “acoustic cue”, bypassing the basal ganglia, affected by  Parkinson’s, and helping patients reroute movement cues.

Parkinson’s dancers performed at the 26th Annual International Traditional Music Festival in Feakle, August 5th-7th.

… more evidence to dust off those dancing shoes, and find your rhythm! much love.
