What Progressive Changes in Brain Vessels Reveal About Parkinson's Disease?
Synopsis
Key Takeaways
- Parkinson's disease causes significant changes in brain blood vessels.
- Research shifts focus from protein deposits to cerebrovascular health.
- Region-specific changes could lead to new treatment options.
- Collaboration with major universities enhances research credibility.
- Exploration of similar changes in other diseases is ongoing.
Canberra, Nov 25 (NationPress) A study conducted by researchers in Australia has uncovered that Parkinson's disease induces notable and progressive alterations in the brain's blood vessels, reshaping our understanding of the condition and potentially paving the way for innovative treatment options.
While the hallmark of Parkinson's disease is the presence of alpha-synuclein protein aggregates, this groundbreaking research indicates that specific changes in the brain's blood vessels contribute to the advancement of the disease, according to a media announcement from Neuroscience Research Australia (NeuRA) on Tuesday.
As NeuRA's postdoctoral researcher Derya Dik stated, “Historically, the focus of Parkinson's research has been on protein buildup and neuronal degeneration, yet our findings highlight significant effects on the brain's cerebrovasculature.”
“Our investigation revealed distinct alterations in the blood vessels of the brain, including a rise in string vessels, which are ineffective remnants of capillaries,” Dik added.
In partnership with the University of New South Wales and the University of Sydney, NeuRA scientists also noted modifications in cerebral blood flow and the functionality of the blood-brain barrier. These findings were published in the journal Brain, as reported by the Xinhua news agency.
The research team believes that targeting these progressive, localized changes could potentially slow the progression of the disease and enhance outcomes for individuals affected by Parkinson's disease.
Furthermore, the researchers are currently exploring whether comparable cerebrovascular alterations exist in post-mortem brain tissue from patients with Alzheimer’s disease and dementia with Lewy bodies, according to the media release.
The World Health Organization (WHO) defines Parkinson's disease (PD) as a neurological disorder that leads to movement difficulties, mental health issues, sleep disturbances, pain, and various other health complications.
“PD progressively worsens over time. While there is no cure, various therapies and medications can alleviate symptoms. Common symptoms include tremors, painful muscle contractions, and challenges with communication. Parkinson's disease is associated with high rates of disability and the necessity for caregiving. Many individuals with PD also experience dementia,” the WHO noted.
