Scientists find new cause of hypertension

A new study has found that high blood pressure may be caused by activity in a brain region known as the "Lateral Face Area" (pFL), which controls breathing and influences blood vessels. Researchers discovered that activating this area leads to blood vessel constriction and increased response of the sympathetic nervous system, resulting in elevated blood pressure. Experiments on rats showed that disabling the function of this region reduces blood pressure, offering a new pathway for treating hypertension, especially in individuals with neurological causes or sleep-related breathing problems. This comes at a time when about 40% of patients have uncontrolled blood pressure despite taking medications, highlighting the need to develop new treatment strategies based on a deeper understanding of the brain's role in the condition.
