-------------------------------------------------TITLE: New metabolomics study traces the path from neurotic personalities to cognitive decline
Individuals who score high in the personality trait of neuroticism have an elevated risk of developing dementia later in life, and recent research points to an imbalance of circulating fatty acids as a potential explanation. A large study of midlife adults suggests that neurotic tendencies are linked to lower blood levels of omega-3 fatty acids, which in turn relates to vascular damage in the brain and a higher likelihood of cognitive decline. The findings were published in the Journal of Affective Disorders.
Neuroticism is a fundamental personality trait describing a person’s tendency to experience negative emotions like anxiety, worry, and irritability in response to stress. Health researchers have consistently linked high levels of this trait to various physical and mental health challenges. Over the past decade, observational evidence has emerged tying higher neuroticism to an increased chance of developing dementia.
The biological pathways connecting a personality trait to a degenerative brain condition remain poorly understood. Experts suspect an indirect route involving cardiovascular health. Neuroticism is known to correlate with negative lifestyle choices that gradually degrade heart health over a person’s lifespan. Notably, high neuroticism is more strongly associated with vascular dementia, which stems from reduced blood flow to the brain, than it is with Alzheimer’s disease.
To investigate the molecular links between personality and cognitive decline, researchers turned to metabolites. These are the small molecules produced when the body breaks down food, drugs, or its own tissues. Because metabolites are the final downstream products of biological processes, they provide a snapshot of both genetic and environmental influences on a person’s physical state.
Yaqing Gao, a researcher at the University of Oxford, led a team to explore whether specific metabolic profiles might explain the personality-dementia connection. The investigators wanted to systematically screen hundreds of blood markers to see which ones tracked with anxious personality traits. From there, they aimed to determine if those same chemical signatures predicted future dementia diagnoses.
The researchers conducted a large study using data from the UK Biobank, relying on information from 215,624 participants aged 40 to 69. At the start of the data collection period, the participants surveyed their neurotic tendencies via a standard psychological questionnaire and provided blood samples.
Nuclear magnetic resonance spectrometry is a sophisticated biochemical method that uses magnetic fields to identify specific types of molecules. Investigators applied this technique to quantify 249 different metabolites in the blood samples. The research team then tracked the participants for a median of about fourteen years to see who developed dementia.
The analysis revealed that neuroticism was associated with roughly half of the evaluated metabolites. The most prominent patterns involved circulating fats. Individuals with higher neuroticism scores tended to have fewer high-density lipoproteins and lower levels of omega-3 fatty acids. At the same time, these individuals exhibited elevated levels of very-low-density lipoproteins, triglycerides, and omega-6 fatty acids.
Omega-3 fatty acids, commonly found in oily fish, are widely considered beneficial for cardiovascular health. Omega-6 fatty acids, often sourced from vegetable oils, are also necessary for human function but can promote inflammation if they vastly outnumber omega-3s in the body. The researchers found that the balance between these two types of fats was an important predictor of future health outcomes.
Biologically, omega-3 and omega-6 fatty acids compete for the same enzymes in the human body. While omega-3s possess properties that protect blood vessels, derivatives of omega-6 fatty acids can promote blood vessel constriction and the production of inflammatory molecules. If a person consumes massive amounts of omega-6 relative to omega-3, the beneficial cardiovascular effects of the latter are easily overwhelmed. The resulting inflammatory environment could progressively compromise the structural integrity of the small vessels feeding the brain.
Only a handful of the metabolites showed a consistent directional relationship with both neuroticism and dementia risk. Specifically, four markers relating to omega-3 levels, including docosahexaenoic acid, were associated with lower neuroticism and a decreased risk of dementia. Conversely, a high ratio of omega-6 to omega-3 was linked to higher neuroticism and an increased risk of dementia.
When zooming in on specific disease subtypes, the research team noticed that a lack of omega-3s was more strongly associated with vascular dementia than with Alzheimer’s disease. The researchers also examined a smaller subset of participants who had undergone brain scans. They evaluated the scans for white matter hyperintensities, which are spots on the brain that indicate damage to small blood vessels. Higher levels of omega-3s corresponded to fewer spots of vascular damage on the imaging.
To better understand whether one factor actually causes another, the team employed an analytical technique known as Mendelian randomization. This method uses natural genetic variations as proxies for certain traits to help rule out external variables that confuse observational studies. The genetic analysis suggested that neuroticism causes a reduction in omega-3 levels. The results also implied that lower levels of the omega-3 docosahexaenoic acid directly cause an increase in white matter damage in the brain.
These metabolic signatures suggest that the link between high neuroticism and dementia might be driven by poor dietary habits. Humans cannot produce an adequate amount of omega-3 or omega-6 fatty acids on their own, making their abundance entirely dependent on food intake. People prone to continuous stress and anxiety may gravitate toward diets low in fish and high in vegetable oils, ultimately depriving their circulatory systems of protective nutrients. This lack of nourishment could gradually compromise the brain’s blood vessels over decades.
The findings come with a few limitations. The metabolic screening platform used in the study relies heavily on lipoproteins and misses other potentially relevant chemicals. Identifying dementia cases through hospital and death records can also lead to misclassifications, as milder cases might easily escape official documentation. The genetic tools used to assess vascular dementia are still relatively weak, meaning the causal inferences must be treated as supportive rather than definitive proof.
Additionally, the participants in the UK Biobank tend to be healthier and from higher socioeconomic backgrounds than the general population. This demographic skew may influence the broader applicability of the outcomes. Observational data remains vulnerable to residual confounding, where unmeasured factors influence both biology and behavior at the same time. The fact that neuroticism and metabolite levels were measured simultaneously in the main analysis prevents researchers from determining precisely how the variables sequentially influence one another.
Future research will require detailed dietary assessments to verify exactly how eating habits govern the relationship between anxious traits and circulating fats. Investigations utilizing broader metabolic screening tools could also uncover alternative biological pathways. If subsequent trials confirm that these causal chains exist, healthcare professionals might recommend dietary modifications or fish oil supplements to help offset the dementia risks associated with highly neurotic personalities.
The study, “Neuroticism, omega-3 fatty acids, and risk of incident dementia,” was authored by Yaqing Gao, Cornelia van Duijn, Thomas J. Littlejohns, and Najaf Amin.

Everytime I think that uploaded #metabolomics data can't get any weirder, I find something else.
Today, it's 1 sample out of 64 that has negative values. ONE out of 64 that has negative values. Unless something weird was done in processing, either all of them should contain negative values or none of them should. 🤦♂️
All missing for one sample, that sort of, might make sense. But 1 of 64 has negatives? WTF. And it's not just one value, it's 64 of 407.

Working with data from Metabolomics Workbench again, and it always feels like the data is yelling at me with the fields in all caps.
Now that I've double checked, the Protein Data Bank file format was like this too, all caps everywhere (even more so).

Why has GC-MS (gas chromatography- electron impact ioniation- mass spectrometry) had such enduring value for the field of metabolomics? How do we identify metabolites based on mass spectrometry data?
I hope you'll enjoy this video explaining the basics of GC-MS and the spectral library methods we use for explaining these spectra!

Why would we choose to measure just a few metabolites instead of doing a broad untargeted survey? In two words: "quantitative precision"
This is the first lecture recording I have produced with my new home video setup!

New preprint!
An Integrated Multi-omic Analysis Reveals Novel Gene-Metabolite Relationships in Human Steatohepatitic Hepatocellular Carcinoma
https://www.medrxiv.org/content/10.64898/2026.01.28.26344977v1Colleagues took paired samples of hepatocellularcarcinoma from several patients (8), and did bulk RNA-Seq, lipidomics, and metabolomics on the samples.
We analyzed the data to see what was different in each modality, as well as what correlations could be found between RNA-Seq and metabolomics.
