Hypertension, dementia, and Parkinson’s disease are some of the most challenging health problems of our time. These conditions, albeit diverse in their presentation and treatment, have all been linked to systemic inflammation and oxidative stress.

Here we explore how these two processes can be targeted with novel drugs and therapies to improve patient outcomes and reduce the incidence of these debilitating conditions.

Systemic Inflammation and Its Targets

While inflammation is an essential part of our immune system, chronic system-wide inflammation can lead to a host of health issues, including hypertension.

Inflammation can cause the endothelial cells lining our blood vessels to become sticky, leading to the formation of plaques that impede blood flow. This can result in high blood pressure and an increased risk of heart attack and stroke.

New drugs targeting inflammation, such as Canakinumab, have shown promising results in reducing the risk of cardiovascular disease, even in patients who do not have high cholesterol levels.

This drug works by blocking interleukin-1 beta, a pro-inflammatory cytokine that has been implicated in arterial thickening and plaque formation. By reducing inflammation, Canakinumab may not only lower the risk of hypertension but also dementia, as chronic inflammation has been linked to the development of Alzheimer’s disease.

Oxidative Stress and Its Targets

Oxidative stress is another critical contributor to hypertension, dementia, and Parkinson’s disease. In this process, free radicals created by our metabolism damage our cells and DNA.

These free radicals can cause inflammation and impair the functioning of vital organs like the brain.

A drug currently being investigated for its effectiveness in combating oxidative stress is MitoQ. MitoQ is a mitochondria-targeted antioxidant that can penetrate the mitochondria, which produce many of the free radicals that cause oxidative damage.

Animal studies have shown that MitoQ can improve cardiovascular function and reverse some of the cognitive impairment associated with aging.

New Discoveries in Dementia

Dementia is a devastating neurocognitive disorder that affects millions of people worldwide.

Two new drugs, Aducanumab, and Donanemab, have recently shown promising results in clinical trials, raising hopes that the progression of Alzheimer’s disease could be slowed or halted.

Aducanumab works by targeting amyloid-beta, a protein that accumulates in the brains of Alzheimer’s patients, forming plaques that disrupt neural connections.

In two large clinical trials, Aducanumab was found to reduce the accumulation of amyloid plaques and improve cognition in patients with early-stage Alzheimer’s disease. Donanemab, on the other hand, targets a different protein called N-terminal tau, which forms neurofibrillary tangles that disrupt the functioning of neurons.

In a phase II clinical trial, Donanemab was shown to reduce the amount of tau in the brain and improve cognition in patients with early-stage Alzheimer’s disease.

Novel Therapies for Parkinson’s Disease

Parkinson’s disease is a neurocognitive disorder characterized by the progressive loss of dopaminergic neurons in the brain.

Current treatments for Parkinson’s disease focus on replacing dopamine with drugs like L-dopa or targeting non-dopaminergic neurotransmitter systems that compensate for the loss of dopamine.

However, novel therapies aim to slow down or stop the ongoing degeneration of dopaminergic neurons.

One such therapy is the use of isradipine, a blood pressure medication that has been shown to protect dopaminergic neurons from oxidative stress and improve motor outcomes in animal models of Parkinson’s disease. Another potential therapy for Parkinson’s disease is the use of GLP-1 agonists, which are currently used to treat diabetes.

GLP-1 agonists have been shown to increase the number of dopaminergic neurons, reduce inflammation, and improve motor outcomes in animal models of Parkinson’s disease.

Conclusion

Hypertension, dementia, and Parkinson’s disease are complex health issues that require a multifaceted approach to treatment.

However, emerging research into targets for inflammation, oxidative stress, and neurodegeneration offer hope for new treatments and therapies that could improve patient outcomes and reduce the incidence of these debilitating conditions.
