- What is oxidative stress? It's when reactive oxygen species (ROS) outnumber the body's antioxidants, leading to cell damage.
- Why does it matter? The brain is highly vulnerable due to its high oxygen demand and low antioxidant defenses.
- How does it harm? ROS damage lipids, proteins, and DNA, disrupting neurons and worsening neurodegeneration.
- How is it measured? Biomarkers like lipid peroxidation, protein oxidation, and DNA oxidation track damage and disease progression.
- Can it be reduced? Supplements like NMN, resveratrol, spermidine, and fisetin may help protect brain health by targeting oxidative stress.
Early detection of oxidative stress and targeted interventions can support long-term brain health.
Uncovering Neurodegenerative Diseases: The Role of ...
How Oxidative Stress Causes Brain Disease
Excess reactive oxygen species (ROS) can harm lipids, proteins, and DNA, disrupting neuronal communication and leading to cell death. Over time, this damage contributes to neurodegenerative conditions like Alzheimer's, Parkinson's, dementia, and ALS. Let’s take a closer look at how ROS directly impacts cells, interferes with brain functions, and causes oxidative changes linked to specific diseases.
Measuring Oxidative Stress in Brain Disease
Researchers use specific biomarkers to quantify oxidative damage caused by reactive oxygen species (ROS). This approach helps track oxidative stress in the brain and its role in neurodegenerative diseases.
Lipid Damage Markers
When ROS attack membrane lipids, they produce lipid peroxidation products. High levels of these products indicate damage to neuronal membranes and ongoing neurodegeneration.
Protein and DNA Damage Markers
Protein oxidation leads to the formation of carbonylated proteins, while DNA oxidation results in oxidized nucleotides. Elevated levels of these markers point to disrupted cellular functions and progression of the disease.
Biomarkers in Treatment Monitoring
Tracking these biomarkers over time helps monitor how a disease progresses and how well treatments are working. This data can guide clinical decisions and provide insights into different stages of the disease.
These measurable biomarkers offer a clearer picture of how oxidative stress evolves during various stages of brain disease.

Markers as Disease Progress Indicators
How Biomarkers Change with Disease Progression
As neurodegenerative diseases progress, oxidative stress biomarkers change in noticeable ways, reflecting the stage and severity of the condition. These changes help doctors assess the disease's advancement and plan treatments. For example, levels of lipid peroxidation products, protein carbonyls, and 8-oxo-dG increase gradually as the disease moves through its stages.
Using Biomarkers to Predict Outcomes
Elevated levels of DNA oxidation markers are linked to faster cognitive decline and a less favorable outlook. This allows clinicians to identify high-risk patients early, tailor treatments based on these evolving markers, and prepare for long-term care needs.
Up next, we’ll dive into methods for reducing oxidative damage and safeguarding brain health.
Brain Health Protection Methods
Efforts to protect brain health focus on limiting oxidative damage and supporting brain function through specific supplements.
