Not so smart They also included a range of measures of intelligence. Overall, the team found no evidence that psychopaths were more intelligent than people who dont have psychopathic traits.

Do psychopaths have high serotonin?

[10,11] found that psychopathy was associated with an increased ratio between the dopamine metabolite HVA and the serotonin metabolite 5-HIAA.

Do psychopaths lack dopamine?

“Our hypothesis was that psychopathic traits are also linked to dysfunction in dopamine reward circuitry,” Buckholtz said. “Consistent with what we thought, we found people with high levels of psychopathic traits had almost four times the amount of dopamine released in response to amphetamine.”

Do psychopaths isolate themselves?
