2 Clinical Trials in progress to confirm that Vitamin D does TREAT Parkinson's Disease

1) Clinical Effects of Vitamin D Repletion in Patients With Parkinson's Disease (VIDIP PILOT)

Estimated completion date Dec 2011 NCT00571285; Contact: Elaine Sperin, LPN esperin@emory.edu or : Shirley Triche, RN, FNP striche at emory.edu
General statement of how the problem will be studied About 150 persons who have PD and low vitamin D levels will participate in this study.
Subjects will be randomly (like flipping a coin) assigned to either high dose vitamin D supplement (54,200 IU weekly)
or the Recommended Daily Allowance (RDA) for older persons (4200 IU weekly of vitamin D).
Subjects will be examined in the clinic before, then 3- and 6- months after taking vitamin D supplement.
Tests of walking speed, Parkinson's rating scales, memory tests and questionnaires of mood, anxiety and fatigue will be administered.
Subjects will be randomized (1:1) to one of the following:

  • 50K IU vitamin D weekly plus 600 IU daily (equivalent to 7743 IU daily)
  • OR Placebo capsule once a week plus a daily MVI senior multivitamin (equivalent to 600 IU daily)

Update Dec 2014 - suspended due to lack of funding

2) Effects of Vitamin D in Parkinson's Disease (PD)

Clinical Trial NCT01119131; Start Date: July 2010; Study Ongoing as of July 2015

The proposed study is a randomized, double-blinded, placebo controlled intervention trial to measure the effects of vitamin D at (10,000 IU/day) versus placebo on balance and falls in Parkinson's disease. We will measure static, dynamic, and ambulatory balance, as well as strength, falls, and cognition before and after 16 weeks of therapy. Dynamic posturography will be used to measure static and ambulatory balance, a device called iMOBILITY will measure a timed up and go, and strength will be measured with the Biodex machine checking knee flexion and extension. Multiple quality of life and cognitive tests will also be performed.
Comment by VitaminDWiki - unfortunately only 16 weeks and no loading dose.
It is unlikely that very many of the participants will get a high enough vitamin D level to make any difference in 4 months


Vitamin D Deficiency-Induced Vertebral Fractures May Cause Stooped Posture in Parkinson Disease

American Journal of Physical Medicine & Rehabilitation:
April 2011 - Volume 90 - Issue 4 - pp 281-286
Sato, Yoshihiro MD; Iwamoto, Jun MD; Honda, Yoshiaki MD

Results: During the 5-yr study period, stooped posture developed in 34 patients; the rest of the 58 patients did not show stooped posture. At baseline, mean serum 25-hydroxyvitamin D and parathyroid hormone levels were 10.9 ng/ml and 73.1 pg/ml, respectively, in the stooped group and 18.6 ng/ml and 56.4 pg/ml, respectively, in the nonstooped group. Bone mineral density in the stooped group was significantly lower than in the nonstooped group. Dietary intake of vitamin D in the stooped group was significantly lower than in the nonstooped group.
During the study period, 19 (22%) patients in the nonstooped group developed new vertebral fracture, compared with 23 (100%) patients in the stooped group.
The mean ± SD percentage changes in bone mineral density were ?6.5 ± 0.6 in the stooped group and ?3.8 ± 0.8 in the nonstooped group.
Mean serum levels of 25-hydroxyvitamin D after 5 yrs were 7.0 ng/ml in the stooped group and 14.1 ng/ml in the nonstooped group.

Conclusions: Stooped posture in Parkinson disease may be caused by vertebral fractures resulting from vitamin D deficiency with compensatory hyperparathyroidism.
Vitamin D supplementation may reduce stooped posture in patients with Parkinson disease.

Vitamin D and neurology - section on PD Wikipedia March 2014

Parkinson's disease is characterized by progressive deterioration of movement and coordination. Patients with Parkinson's disease lose dopaminergic (DA) neurons in the substantia nigra.,[13] a part of the brain that plays a central role in such brain functions as reward, addiction, and coordination of movement. Studies suggest that low vitamin D levels could play a role in PD, and in one case report, vitamin D supplements lessened parkinsonian symptoms. In a study of vitamin D receptor knockout mice, mice without VDR exhibited motor impairments similar to impairments seen in patients with Parkinson's disease.[6] One proposed mechanism linking vitamin D to Parkinson's disease involves the Nurr 1 gene. Vitamin D deficiency is associated with decreased expression of the Nurr1 gene, a gene responsible for development of DA neurons. It is therefore plausible that a lack of Nurr1 expression leads to impaired DA neuronal development. Failure to form DA neurons would lead to lower dopamine concentrations in the basal ganglia. Additionally, rats lacking Nurr1 exhibited hypoactivity followed by death shortly after birth.[13]
