若年成人の高血圧は、脳のサイズの縮小と認知症に関連しています, 研究は見つけます

若年成人の高血圧は、脳のサイズが小さくなり、認知症のリスクが高まることに関連しています, 新しい研究が発見した.

年齢の間に高血圧と診断された成人 35 に 44 had smaller brain sizes and were more likely to be diagnosed with dementia compared to adults their age with normal blood pressure, according to a study published Monday in Hypertension, a journal of the American Heart Association.
Adults under age 35 had the largest reductions in brain volume compared to adults their age without high blood pressure, which could come with adverse health effects, 博士は言った. James Galvin, professor of neurology at the University of Miami’s Miller School of Medicine in Florida. He was not involved in the study.
    The smaller brain volumes in younger aged individuals as a consequence of their high blood pressure may put them at higher risk of dementia as they age,” 彼は言った.
      Researchers used magnetic resonance imaging (MRI) scans of 11,399 people ages 55 years and younger who were diagnosed with high blood pressure as well as 11,399 people without hypertension. The participants information came from the UK Biobank, a database of anonymous health information from around half a million people. The study authors did follow ups with participants over an average of 11.9 years later to see if they actually were diagnosed with dementia.
        Hypertension is common in adults ages 45 に 64 and is associated with brain health and dementia later in life, but little is known about how the age of when high blood pressure is diagnosed affects these associations, said senior study author Dr. Mingguang He, professor of ophthalmic epidemiology at the University of Melbourne in Australia, 声明の中で.
        If this is proven, it would provide some important evidence to suggest earlier intervention to delay the onset of hypertension, which may, in turn, be beneficial in preventing dementia,” 彼は言った.
          Having a smaller brain volume means there is a loss of neurons and the connections they have with each other, said Donna Arnett, dean of the University of Kentucky College of Public Health in Lexington, 研究に関与しなかった人.
          Larger brain volumes are associated with better cognitive function while loss of brain volume is associate with the development of dementia, Galvin said. Hypertension over time impacts blood flow to the brain and can potentially damage the brain structure, 彼が説明しました. If left untreated, it affects brain function, Galvin added.
          時間とともに, young people may be impacted more because they face a longer lifetime duration of blood pressure on the brain, Arnett said.

          Preventing hypertension at all ages

          It’s important to take care of brain health at an early age to prevent hypertension, which could lead to adverse health effects like a smaller brain size and dementia, Arnett said.
          Getting enough exercise そして eating a healthy diet can help lower high blood pressure, 博士は言った. Glen Finney, fellow of the American Academy of Neurology, 研究に関与しなかった人.
          Part of a healthy diet includes moderating alcohol intake そして keeping blood sugar levels in the normal range for your age, 彼は言った. Reducing your salt intake can also help lower blood pressure, Galvin added.
          If lifestyle changes are not enough, Galvin recommended speaking with your doctor about taking blood pressure medication.

          Reducing other risk factors for dementia such as obesity, diabetes, high cholesterol and smoking also decreases your risk of developing dementia, Galvin said.
            This study reaffirms the importance of young people getting regular health check-ups and taking good care of their health in early years, Finney noted.
            If you notice changes in memory, thinking or behavior as you age, let a medical professional know, 彼が追加した.
