I've done a little digging since the possibility of have B-12 deficiency was presented. Another glove that fits.

Effect of L-dopa on plasma homocysteine in PD patients

Relationship to B-vitamin status

http://www.neurology.org/cgi/content/abstract/60/7/1125

Conclusion: L-Dopa can cause hyperhomocysteinemia in PD patients, the extent of which is influenced by B-vitamin status. The B-vitamin requirements necessary to maintain normal plasma homocysteine concentrations are higher in L-dopa-treated patients than in those not on L-dopa therapy. B-Vitamin supplements may be warranted for PD patients on L-dopa therapy.

we must have potassium - L -dopa zaps potassium!
and that is an electrical connector for our electric bodies!

research is there - find it please...

adding another link to an abstract that is more direct. i'll have to look for this study they mention at the bottom of this article tomorrow...yawn. Did I miss something? This news about a link between anemia and l-dopa is new to me. This article takes it to the next serious level of risk.

my meds quit working well 3 years ago - until I found the key -
B-12 and good food with good nutrients from good soil...

I have been talking B-vitamins -because we need them!
you can not get well on medicine -unless as hyprocrates says:
let your food be your medicine - organic foods - not gm foods -

nutrtion will cure what bigpharma cant -
thus bigpharma would love to get the vitamin biz -
then we would have zero freedom to heal ourselves
or think for ourselves -
thats may 3 bucks worth -

Vitamins, minerals, and mood.Kaplan BJ, Crawford SG, Field CJ, Simpson JS.

In this article, the authors explore the breadth and depth of published research linking dietary vitamins and minerals (micronutrients) to mood. Since the 1920s, there have been many studies on individual vitamins (especially B vitamins and Vitamins C, D, and E), minerals (calcium, chromium, iron, magnesium, zinc, and selenium), and vitamin-like compounds (choline). Recent investigations with multi-ingredient formulas are especially promising. However, without a reasonable conceptual framework for understanding mechanisms by which micronutrients might influence mood, the published literature is too readily dismissed. Consequently, 4 explanatory models are presented, suggesting that mood symptoms may be expressions of inborn errors of metabolism, manifestations of deficient methylation reactions, alterations of gene expression by nutrient deficiency, and/or long-latency deficiency diseases. These models provide possible explanations for why micronutrient supplementation could ameliorate some mental symptoms. PsycINFO Database Record (c) 2007 APA, all rights reserved

The role of vitamins and minerals in energy metabolism and well-being.Huskisson E, Maggini S, Ruf M.
King Edward VII Hospital, London, UK.

Physicians are frequently confronted with patients complaining of fatigue, tiredness and low energy levels. In the absence of underlying disease, these symptoms could be caused by a lack of vitamins and minerals. Certain risk groups like the elderly and pregnant women are well-recognized. Our aim was, therefore, to find out if other, less well-established groups might also be at risk. Thus, the objectives of this review are: to describe the inter-relationship between micronutrients, energy metabolism and well-being; identify risk groups for inadequate micronutrient intake; and explore the role of micronutrient supplementation in these groups. A review of the literature identified an important group at risk of inadequate micronutrient intake: young adults, often women, with a demanding lifestyle who are physically active and whose dietary behaviour is characterized by poor choices and/or regular dieting. Micronutrient supplementation can alleviate deficiencies, but supplements must be taken for an adequate period of time.

Common Misdiagnoses Due to Vitamin B12 Deficiency
One Thing the Drug Companies Don't Want You to Know

http://www.associatedcontent.com/art...min.html?cat=5

Recently, I sent a couple of my family members to get tested for a gene called Plasminogen Activator Inhibitor. Reason being is the fact I was diagnosed with it myself and learned that it also may be genetic. My doctor wasn't able to tell me that much about this gene due to the fact that it is pretty new to American Doctors. So I had to do most of the research myself to get any straight answers about this Plasminogen Activator Inhibitor Gene. I did find that this gene has been associated with a wide variety of diseases and disorders. The majority of the problems that derive from this particular gene are also a lot of the common complaints that my family members have.

Luckily the family members that did get tested did not come back positive for Plasminogen Activator Inhibitor Gene. Instead they came back with test results that revealed a Vitamin B12 Deficiency. This would have been easily overlooked if it wasn't for the fact that my family members had asked for extensive blood work to be done. Actually Vitamin B12 Deficiency is one of the most common disorders that are overlooked by Physicians. It's not that your Physician lacks common sense; it's just that they have been conditioned to look for other ailments. The Prescription Drug Manufacturers target Doctors more then they target us. In fact I read a story written by a man who left medical school in the United States. His reasons had more to do with his morals then anything. In his story he explained that the majority of his classes and seminars focused on prescribing medication rather then preventive healthcare. He ended up moving over seas to do just that, focus on preventative healthcare, not writing out scripts all day.

So you may be wondering what conditions are linked with Vitamin B12 Deficiency?

Here are the conditions that I was able to find, there may be more.

Pernicious Anemia

Atherosclerosis

The Early onset of Alzheimer's disease

Muscle Tremors

Depression

Osteoporosis

Cataracts

Strokes at an early age

Infertility

Metabolic Syndrome

And, Dementia
