Default The American Prevalence of Parkinson's disease

Parkinson's prevalence estimated by a state registry

PubMed, PMID: 15022187 [PubMed - indexed for MEDLINE], Strickland D, Bertoni JM, Epidemiology Section, Department of Preventive and Societal Medicine, University of Nebraska Medical Center, Omaha, Nebraska, USA. Daniel.Strickland@KP.org

http://www.ncbi.nlm.nih.gov/pubmed/15022187

A solid understanding of the descriptive epidemiology of a disease is essential in etiologic investigations; this includes prevalence and incidence, as well as groups within the larger community who may have noticeably lower or higher rates. We ascertained the usefulness of a non-traditional registry in describing Parkinson's disease (PD) patterns in a community. A passive surveillance PD registry in Nebraska began data collection on 1 January 1997. All physicians were required to report PD diagnosis, pharmacists reported new prescriptions of anti-PD drugs (PD cases were confirmed later with the prescribing physician), and there was a patient self-report mechanism. The overlap of reporting by the sources allowed estimation of the number not reported by any source, using the statistical technique "capture-recapture." As of January 2000, the Nebraska PD Registry had reports of 5,062 PD patients. The number not reported by any Registry reporting source was calculated to be 117, leading to an estimated total of 5,179 cases and a prevalence of 329.3 per 100,000 population. Tabulations of age- and gender-specific prevalence rates, as well as county-level estimates, allow examination of areas of elevated or lowered prevalence. The combination of a passive surveillance system and capture-recapture technique presents a useful method for epidemiologic description, and more traditional survey methods could benefit by including capture-recapture capability.

THE AMERICAN PREVALENCE OF PARKINSON'S DISEASE

23rd January 2010 - New research, Neuroepidemiology [2010] 34 (3) : 143-151 .Annals of Neurology [2009] 66 (6) : 792-798 (Wright Willis A, Evanoff BA, Lian M, Criswell SR, Racette BA.) Complete abstract

http://www.************/parkinsons.d...ews/100123.htm Link does not work. Internet search title of this item to see it online at the website.

The prevalence of Parkinson's Disease in the U.S.A. has been found to differ enormously according to location, age and race. The prevalence of Parkinson's Disease in some counties was found to be nearly 12 times higher than in other counties. Urban areas were more affected than rural areas. Elsewhere, the opposite is usually true. Parkinson's Disease is far from being evenly spread across the U.S.A.. The study revealed a concentration of Parkinson's Disease in the Midwest and Northeast regions of the U.S.A.. Nebraska was previously shown to be the worst affected Complete abstract. In the over 65s there was found to be a prevalence in some areas of 1 in 7, making it in those places a common medical disorder. Whites were affected with Parkinson's Disease about twice as much as Blacks and Asians, though this difference is progressively decreasing, especially between Blacks and Whites. For more current news go to Parkinson's Disease News.

For more details of the above research see:

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2865395/

In particular, see the maps showing the different rates of PD across the US.

Explain the differences and, in my opinion, we are much closer to beating Parkinson's.

John,

I agree that the map is quite telling. My theory is that for many of us in urban areas the culprit is not pesticides but the air we breathe. A substance referred to as MMT is in our gasoline as a substitute for lead (ironically) and it's main component is Manganese. It is fine particulate matter that we breathe in and that easily passes the blood brain barrier. Now check out the research on Pubmed for the incidence of Parkinsonism in populations near Manganese production factories and in highly polluted areas like Mexico City.
There is actually an article tying MMT to Alpha-Synuclein aggregation with brain damage beginning in childhood! I have written embarrassingly long posts on this if you search the archives.

When I look at that map it further cements the MMT theory for me. Look at the rate of prevalence in the LA region for example vs. the rest of California and the entire Western region. LA is legend for its expressway traffic jams. Though with the population rate, why isn't PD more prevalent? I am guessing the dry air has a lot to do with it. Look at rates for Seattle. Fewer people but moist air. Not exactly scientific, but I am thinking we could easily apply weather phenomenon and scientific methodology to the theory. Does anyone else find this plausible? Any other ideas in looking at the map? I am not sayin it is just MMT but air pollution in general...incidentally my childhood home backed up to an expressway.

This is all keeping in mind the multiple hit theory of sporadic PD...another person may find their environmental trigger is something entirely different if they have one at all since one can acquire the disorder through genetics alone.

Default maps

Hi John, Laura and all,

I find these maps of incidents or prevalence really interesting. They seem to be somewhat concrete data in a PD world otherwise full of questions and uncertainties.
Although I grew up in the Chicago and then the NYC suburbs (both high red areas of prevalence), I have spent my adult life on the west coast and know that geography best.
I focused in on the one and only red area in California on the first map.
I have lived close to that area, that is south of Lake Tahoe and north of Yosemite. It looks like it might be Alpine county. It is very rural and in the mountains and almost pristinely clean.
The only natural landmark there that comes to mind is there are several hot springs in that area- the big ones Markleeville and Woodfords. Perhaps the water in that area has certain minerals or impurites?? Also, that area got populated during the silver rush and there are/were silver mines nearby. Perhaps silver in the water?? All speculation of course.
If only we could cross reference all the data that is out there.

Default We hold answers too...

Victorialou,

Thanks for sharing your background. This is precisely the sort of "fuzzy" data that researchers need to get a much quicker grasp of what our shared experiences or exposures might be. We all need to be in that National registry for PD and MS that can run queries or analyze.

What makes this all the more complex is that most likely we all have very individual paths but meet at the same watering hole so it is hard to say with any confidence that it is due to just one environmental thing in an area. It could be that your PD is more due to genetics (it can be just that) or maybe a concussion or viral infection when you were younger...I'm not even sure we need an environmental toxin component.

What I don't like is how we living with all these clues are all but ignored except for drug trials because that is where the profit lies. No one makes any money testing us for trace metal levels. I think they know enough environmental triggers at this point so are we not given a battery of tests to look for pesticides, manganese and other trace elements or metals in all of us? Gee, this may actually lead to putting some of the puzzle together but no one bothers with meta data it seems...

A few other PD correlates to add and extend the map globally. PD seems to occur most frequently at higher latitudes....rare to find it below the equator. I think in US, the highest rate of incidence is in Minnesota (some one correct me if I am wrong). In Europe, it is Scandinavia that is hit the hardest. We hear that more men are diagnosed than women, but in Japan it is just the opposite. I think by studying these oddball or anomaly things we can find a lot of answers too.

In addition to local factors and genetics, my hunch is that there is a climatological connection.

The Parkinson's distribution maps hint at a relationship between prevailing wind direction and PD. In itself this is not causal. However, one possible causal mechanism follows from the wind affecting surface ozone levels [1]. Especially in summer, these seem to be distributed in a similar way to PD. In turn, ozone levels affect nitric oxide levels in the body [2]. NO may be implicated in Parkinson's both directly [3] and indirectly, by increasing the permeability of the BBB [4].

Proper statistical analysis is required.

Inuit in northern Canada have a high rate of PD. And a low rate of heart disease, even those who traditionally lived on meat and fat and fish, with no fibre, no grain, no vegetables and no fruit.

All of this is madness. They bring out these maps showing that one place has 12 times more PD than another place, but the research money goes to finding a new flavour of agonists or new packaging for sinemet. I repeat again: I am waiting for the cherry-flavored sinemet in bubble-gum format, with those coupons you can collect to get free gifts and neat stuff.

Is there an epidemiologist in the house? A medical detective to unravel the mystery? Like Dr. Irving Selikof, who was a simple GP in a small town when he tracked down the reason so many of his patients had forms of cancer such as mesothelioma. He tracked it down: asbestos. He went on to become a top researcher at Mt. Sinai hospital in New York. But when he made the discovery, that resulted in asbestos being outlawed around the world, he was a simple family doctor in Patterson, New Jersey. He paid attention to his patients and, single handed, found the link with asbestos, and then used maps such as these to hunt down every source of asbestos blowing in the wind.
Epidemiologists have a different set of skills; they hunt down links; it's not the same gang as the pill designers. Those maps go way beyond co-incidence. Is there any medical curiosity left out there at all? Are there any epi - experts taking this on?

I too would like to see more epidemiological efforts.

Let's accelerate existing efforts: using the web, Excel and our own unique experiences we can become epidemiologists. We probably won't be the best, but we can become good enough to make a difference.

John,

Liking the idea of this...we have broached doing our own studies right here in this forum.

I am a librarian and like everyone else do not want to waste away while the powers that be do nothing. Count me in.

Lightbulb too many wrong diagnosis?

i believe the PET scan is the only way to tell for sure of this illness,
and the meds arent a cure....
the MRI is good for ruling out tumors etc...
so we need the PET scan to know for positive...
