Diabetes Drug Mounjaro May Help Slow the Progression of Parkinson’s Symptoms

New research suggests that a medication typically used for diabetes might also slow down the early stages of Parkinson’s disease. In a recent study, researchers observed that Lixisenatide, a drug known for treating diabetes, showed promising results in managing Parkinson’s symptoms. 

Participants who received Lixisenatide for a year experienced little to no progression in their motor skill deterioration compared to those who took a placebo. While these findings are encouraging, experts believe that more extensive and long-term studies are needed to fully understand the potential benefits. In this blog, we’ll explore the connection between Parkinson’s disease and diabetes and discuss how diabetes medications like Mounjaro Pen and Ozempic can reduce the progression of Parkinson’s symptoms.

Can Diabetes Drugs Treat Parkinson’s?

A recent study in France offers hopeful insights. Published in The New England Journal of Medicine, this research followed 156 individuals recently diagnosed with Parkinson’s. These participants, whose motor skills had not yet significantly declined, were part of a rigorous trial. They were either administered lixisenatide—a drug commonly used for type 2 diabetes—or a placebo, all while continuing their regular Parkinson’s medications.

The results after one year were promising. Those who received lixisenatide experienced almost no deterioration in motor skills—a common progression in Parkinson’s—while those who took the placebo witnessed a decline in their abilities. However, it’s important to note that about half of the lixisenatide group experienced nausea, and 13% reported vomiting.

Dr. Robert Gabbay, a leading expert from the American Diabetes Association, finds these results exciting. He highlighted that this study serves as a proof of concept, suggesting that GLP-1 receptor agonists like lixisenatide could potentially offer protective benefits against Parkinson’s. This opens up possibilities for other similar medications, such as Ozempic, Wegovy, and Zepbound, to be explored in future research.”

How Are Parkinson’s Disease and Diabetes Connected?

What ties Parkinson’s disease and diabetes together? Despite being distinct conditions, Parkinson’s—a neurological disorder marked by tremors and motor difficulties—and diabetes—a disease characterized by insulin resistance—share some surprising similarities. Dr. Daniel Truong, a neurologist and the medical director of the Truong Neuroscience Institute, explains how these two conditions may be interlinked. Both Parkinson’s and diabetes are influenced by several overlapping factors:

  • Insulin resistance and glucose dysregulation: Problems with how the body manages insulin and glucose can occur in both conditions.
  • Inflammation and oxidative stress: Chronic inflammation, which can damage cells, is a common thread.
  • Mitochondrial dysfunction: Both diseases can involve issues with mitochondria, the energy-producing structures in cells.
  • Alpha-synuclein pathology: This involves the accumulation of abnormal protein in the brain, affecting both diabetics and individuals with Parkinson’s.
  • Shared genetic factors: Some genetic risks are common to both Parkinson’s and diabetes.

Dr. Truong highlights that ongoing research is deepening our understanding of these connections. “Studies have suggested that having diabetes may increase the risk of developing Parkinson’s and vice versa,” he notes. This crossover is particularly evident in how both diseases share mechanisms like inflammation and oxidative stress, further linking diabetes to the neurological decline seen in Parkinson’s.

Dr. Daniel Truong further delves into the scientific details connecting diabetes and Parkinson’s disease. He explains that problems with mitochondria, which are crucial for energy production in cells, play a significant role in both conditions. In diabetes, mitochondrial dysfunction can lead to issues with insulin resistance and the deterioration of beta cells, which are essential for producing insulin. Similarly, in Parkinson’s disease, impaired mitochondria are a major factor in the degeneration of neurons that produce dopamine, a key neurotransmitter. Additionally, Dr. Truong highlights intriguing findings about alpha-synuclein, a protein linked to Parkinson’s. This protein’s abnormal accumulation, known as alpha-synuclein pathology, may not only affect the brain but could also appear in the pancreas of those with diabetes. 

Can You Use Diabetes Drugs to Treat Parkinson’s Disease?

Dr. Daniel Truong discusses the promising potential of diabetes medications, specifically GLP-1 receptor agonists, in treating Parkinson’s disease. These drugs, including popular options like Ozempic and Wegovy, originally designed for type 2 diabetes, operate by mimicking a gut hormone that regulates blood sugar levels. Interestingly, they also impact the brain’s hunger centers, contributing to their noted effect on weight loss. However, be cautious about the side effects of Mounjaro.

Dr. Truong highlights the neuroprotective properties of these medications, such as lixisenatide, which could benefit those with neurological disorders like Parkinson’s. He explains that the overlapping characteristics between diabetes and Parkinson’s, such as insulin resistance and glucose metabolism issues, suggest that GLP-1 receptor agonists could help mitigate Parkinson’s symptoms.

Supporting this, Dr. Truong mentions research indicating a lower prevalence of Parkinson’s among diabetes patients treated with GLP-1 receptor agonists compared to those on other diabetes treatments. This emerging evidence points to shared pathways between the two diseases, underscoring the potential for these drugs to address both conditions effectively.

Study limitations

Dr. Daniel Truong notes that while the research on using GLP-1 receptor agonists like lixisenatide for Parkinson’s is promising, there are several areas that need further exploration to fully understand and optimize this treatment approach. He stresses the importance of determining the most effective doses, exploring how these drugs might work in combination with other therapies, and assessing their overall safety and tolerability for long-term use.

Parkinson’s disease involves not just physical motor symptoms but also a range of non-motor symptoms, including cognitive decline, difficulties with automatic bodily functions, and mental health issues. Dr. Truong emphasizes the need for future research to examine whether treatments like lixisenatide can also alleviate these non-motor symptoms, which are often just as debilitating.

Moreover, while lixisenatide shows potential neuroprotective effects that could slow the progression of Parkinson’s, the exact mechanisms behind these benefits are still not completely understood. Dr. Truong calls for more studies to delve into how this drug impacts inflammation, oxidative stress, mitochondrial function, and alpha-synuclein accumulation in the brain.

Conclusion

The exploration of diabetes medications like GLP-1 receptor agonists in treating Parkinson’s disease is unfolding new possibilities. Dr. Daniel Truong’s insights underscore the potential of these drugs, including opportunities to buy Mounjaro from Canada to address both motor and non-motor symptoms due to shared biological pathways with diabetes. While promising, this research is still in its early stages, necessitating further studies to fully understand the treatments’ effectiveness and safety. As we advance, these findings could significantly influence both the management of Parkinson’s and our broader understanding of neurodegenerative diseases.
