Exploring heart-brain axis alterations in Parkinson's disease.

Neurodegenerative diseases such as Parkinson's disease (PD) are controlled by a sophisticated network known as the heart-brain axis. This chapter delves deep into the pathophysiology of PD, exploring in detail the links between the brain and the heart, covering topics as diverse as autonomic dysfunction, cardiac sympathetic denervation and neuroinflammation. We investigate the potential for genetics, proteomics, and biomarkers to radically alter the course of neurodegenerative and cardiovascular disease diagnosis and treatment. Protective medications, deep brain stimulation, and behavioural modifications are some of the newer and more established methods that have emerged in recent years to maintain the health of the heart and brain, two of the body's most important systems.Ultimately, this chapter argues that to treat Parkinson's disease (PD) effectively, it is essential to opt for a multidisciplinary approach that takes into account both the neurological and cardiovascular aspects of the condition.
