The Genetics of Neuroticism Slowly Unpicked

April 15, 2016

(Medical News Today) – Neuroticism is a human trait found across all cultures, making it a subject of interest since personalities were first studied. In a nutshell, neuroticism is the tendency to respond to threat, loss or frustration with negative emotions; it is considered to be one of five fundamental personality traits that we all display to some degree. Although in itself, it is not necessarily a health issue, it is known to be associated with other, more serious conditions. Among others, neuroticism is associated with obesity, anxiety disorders, substance misuse and schizophrenia. There is also evidence that our level of neuroticism predicts our quality and longevity of life.  As with any psychological trait, the environment plays a part, but twin studies have shown that around 40% of trait variance for neuroticism is heritable.
