According to a study, neurotic personality traits are most likely to be caused by diastolic blood pressure, which is the lower of the two numbers in a blood pressure reading. <br /><br />The findings were published in the journal General Psychiatry. And keeping it under control can help curb neurotic behaviours, anxiety, and heart and circulatory diseases, researchers concluded. <br /><br />High blood pressure is a major risk for cardiovascular disease and is thought to be associated with psychological factors, such as anxiety, depression, and neuroticism--a personality trait characterised by susceptibility to negative emotions, including anxiety and depression.<br /><br /> In a bid to find out, the researchers used a technique called Mendelian randomisation. This uses genetic variants as proxies for a particular risk factor to obtain genetic evidence in support of a causal relationship, reducing the biases inherent in observational studies.<br />
