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

Part of a healthy diet includes moderating alcohol intake
そして keeping blood sugar levels in the normal range for your age

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.
