US EditionWhat Makes a Psychopath? Science May Have the Answer
- A 2025 research article in a peer-reviewed psychiatry journal investigated brain structure differences in 39 adult males diagnosed with psychopathy using sophisticated neuroimaging methods.
- Researchers conducted the study to clarify longstanding questions about brain structures linked to psychopathic traits, acknowledging limitations like small sample size and varying MRI scanners.
- The study found significantly lower total brain volume—about 1.45 percent less—in psychopathic individuals, especially in regions involving emotion, behavior control, and reward processing such as the basal ganglia, thalamus, and right subiculum.
- Researchers reported evidence of extensive abnormalities in brain maturation and identified a robust neurobiological connection between antisocial behavior and decreased brain volume in multiple brain regions.
- These results advance understanding of the neurobiology of violent and antisocial behavior and could inform future treatment and rehabilitation strategies for people with psychopathic traits.

Psychopathic personality traits are associated with experimentally induced approach and appraisal of fear-evoking stimuli indicating fear enjoyment
The extent to which deficits in the perception and experience of fear contribute to psychopathic symptoms is an ongoing matter of debate. Traditional theories emphasize diminished threat processing as the core fear deficit in psychopathic individuals, whereas recent approaches, such as the fear enjoyment hypothesis (FEH), propose that anomalies in the subjective experience of fear are related to interpersonal-affective psychopathic traits. In or…
