In recognition of November as Alzheimer’s Awareness Month, this is blog post #4 of 4 in my series, to highlight Alzheimer’s research and shed light on ways we can preserve our brain health and reduce the risk of Alzheimer’s disease.
Researchers in Denmark recently reviewed a nationwide study to examine the relationship between pre-eclampsia (the onset of hypertension during pregnancy) and diagnosis of dementia later in life.
Subjects included all women in Denmark with at least one pregnancy lasting 20+ weeks. Researchers found that women with a history of pre-eclampsia had 3x greater risk of vascular dementia (dementia caused by impaired blood flow to the brain) compared to women without a history of pre-eclampsia. Interestingly, the authors note that BMI, hypertension, diabetes and cardiovascular disease were unlikely to explain the association.
I am not surprised by this research finding since unmanaged hypertension during midlife is already a well-established risk factor for vascular dementia– high blood pressures can narrow and damage the blood vessels in the brain. If you have a history of pre-eclampsia or current hypertension, make sure it’s controlled under the guidance of your primary care provider, and consider adopting other brain-healthy habits like regular exercise, lifelong learning, and a Mediterranean style diet. And if you’re concerned about your medical history, consider consulting with a neurologist who specializes in brain health; if you need help getting started, visit www.northshore.org/brainhealth.
