In the management of Parkinson's disease, due to the chronic nature of Parkinson's disease (PD), a broad-based program is needed that includes patient and family education, support-group services, general wellness maintenance, exercise, and nutrition. At present, no cure for the disease is known, but medications or surgery can provide relief ...
Parkinson's disease is the 2nd most prevalent neurological disorder within the United States and Europe, affecting around 1% of the population over the age of 60. [1] While the link connecting the onset of Parkinson's disease to environmental factors is known, the link between dietary patterns and the disease is just beginning to be researched more fully.
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. [7] 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 ...
In addition to calcitriol, other vitamin D metabolites may contribute to vitamin D's biological effects. For example, CYP11A1, an enzyme chiefly known for its role in steroidogenesis, has been found to hydroxylate vitamin D3 at several positions, including C-20, C-22, and C-23, without cleaving the side chain.
Vitamin D compounds, specifically cholecalciferol (D3) and ergocalciferol (D2), are used in rodenticides due to their ability to induce hypercalcemia, a condition characterized by elevated calcium levels in the blood. This overdose leads to organ failure and is pharmacologically similar to vitamin D's toxic effects in humans.
It is used to prevent and treat lack of calcium and vitamin D in the elderly, as well for osteoporosis in combination with other medications. [ 1 ] [ 2 ] In 2022, the combination, calcium/vitamin D was the 246th most commonly prescribed medication in the United States, with more than 1 million prescriptions.
This is primarily co-administered with L-DOPA to combat Parkinson's disease. Administration can prevent common side-effects, such as nausea and vomiting, as a result of interaction with D 2 receptors in the vomiting center (or cheomoreceptor trigger zone) located outside the blood–brain barrier .
Vitamin D deficiency is associated with increased mortality in critical illness. [49] People who take vitamin D supplements before being admitted for intensive care are less likely to die than those who do not take vitamin D supplements. [49] Additionally, vitamin D levels decline during stays in intensive care. [50]
