  • Diastolic blood pressure is when the heart relaxes to fill with blood.
  • It is considered too high above 90 mmHg.
  • In France, nearly 12 million people were treated for high blood pressure in 2017, according to Health Insurance.

Blood pressure is linked to heart health, in case of hypertension the risk of cardiovascular disease is high. But a new study, published in General Psychiatry, shows that too high blood pressure can also have consequences on mental health. According to their work, diastolic blood pressure, which corresponds to the minimum blood pressure, can cause neurotic disorders.

What are the links between blood pressure and mental health?

The authors of this research worked on eight datasets containing DNA, extracted from blood samples. They used a technique called “mendelian randomization“to estimate the effect of blood pressure on mental health: it consists of using genetic variants to study a particular risk factor, in order to have genetic evidence of a causal relationship, “thereby reducing the biases inherent in observational studies“, specify the authors. In their work, the scientists took into account four psychological states: anxiety, depressive symptoms, neurotic disorders and subjective well-being.

The analysis revealed that high blood pressure and diastolic blood pressure had significant effects on neurotic disorders. However, they had no effect on anxiety, depressive symptoms or subjective well-being. Further study showed that it was not hypertension, but diastolic blood pressure that was significantly associated with neurotic disorder. “Blood pressure connects the brain and the heart, and therefore may promote the development of personality traits.” they explain.

What is a neurotic disorder?

But the disorder itself could also harm heart health. “People with neuroticism experience high stress more frequently, which can lead to elevated blood pressure and cardiovascular disease., say the authors. Sometimes called neurosis or neuroticism, neurotic disorder manifests as “excessive anxiety, hysterical symptoms, phobias, obsessive and compulsive symptoms, depression“, according to Inserm.”People with neuroticism can be sensitive to criticism from others, are often self-critical, and easily develop anxiety, anger, worry, hostility, self-consciousness, and depression.”, develop the authors of this study. For them, it is essential to better monitor diastolic blood pressure, to reduce the risk of mood disorders, neurotic disorders, and of course cardiovascular diseases.
