Sir,

Always on the lookout for articles from Neurology India, one in particular[1] has attracted a lot of attention because the results are really important. In this context, Ozturk and colleagues addressed a priority issue in clinical research demonstrating that bone mineral density and vitamin D (VitD) levels are decreased at the early stages of Parkinson's disease (PD) and they were adversely affected with the progression of the disease.[1] Considering the effectiveness of VitD in many organs and its significant role in maintaining general health, we applaud the authors for pursuing this topic.[1] Moreover, the possibility of relating VitD concentrations as a biological indicator for possible cardiac abnormalities in patients with PD also deserves some reflections.

PD is one of the most frequent age-related neurodegenerative disorders that affects millions of people globally and has no cure, the prevalence of which will double by 2030.[2] Thereby, several studies have shown that patients with PD have a higher risk of mortality compared with the general population.[2] Sudden unexpected death in PD (SUDPAR), a rare but fatal event, contributes to the increased risk of mortality in patients with PD.[2] While the specific causes of SUDPAR are still unknown, the results of translational studies suggest that cardiac abnormalities and autonomic dysfunction play a possible “direct” role in SUDPAR, since ~60% of PD patients have cardiovascular disturbances because of frequent autonomic disturbances in PD.[2] Despite the formidable progress made in relation to PD, much still needs to be done.[2] At least in the last decade, it is well discussed that low VitD levels and PD are considered bad fellows.[1] Importantly, studies have also been shown that VitD is involved in the regulation of the cardiovascular system.[3] Thus, several studies clearly indicate that VitD deficiency is related to the genesis of coronary heart disease, cardiovascular dysfunction, and hence, sudden cardiac death.[3] Furthermore, low VitD levels are also associated with arterial hypertension, left ventricular hypertrophy, congestive heart failure, and chronic vascular inflammation.[3] Experimentally, our research group recently demonstrated a link between cardiac tissue changes and cardiac functional abnormalities early after the intrastriatal 6-hydroxydopamine (6-OHDA) lesion models of PD.[4]

Considering that PD is a systemic disease, we will also have to explore the specific mechanisms of action that vitamin D plays in order to improve cardiac function and prevent possible cardiac abnormalities present in patients with PD.
