Preeclampsia impacts as much as 15% of girls. Left untreated, preeclampsia can result in severe, even deadly, problems for mom and child. Even after being pregnant, preeclampsia could cause long-term harm to a lady’s kidneys, coronary heart and mind.
Preeclampsia additionally has been related to elevated dangers of coronary heart illness, stroke and cognitive decline, in addition to smaller mind volumes, later in life. Nevertheless, no dependable early markers can be found to find out which ladies are in danger.

On this research, researchers explored whether or not extracellular vesicles small fluid-filled particles of mind cell membranes circulating within the blood might be present in ladies years after their affected pregnancies.
Utilizing well being report knowledge from the Rochester Epidemiology Undertaking, a cohort of 40 ladies 33 with a historical past of gentle preeclampsia and 7 with extreme preeclampsia have been matched to 40 ladies who had uncomplicated pregnancies. In comparison with the management group, ladies with a historical past of extreme preeclampsia had a considerably increased focus of extracellular vesicles that have been constructive for amyloid beta, which is a poisonous mind protein believed to be a vital part of Alzheimer’s illness.
The presence of amyloid signifies mind cell harm and irritation. The researchers discovered that ranges of amyloid circulating within the blood additionally have been elevated.
“These markers of mind cell harm and irritation within the blood of girls with a historical past of preeclampsia might result in new diagnostic and therapeutic methods to enhance ladies’s cognitive well being over their lifetimes,” says Vesna Garovic, M.D., Ph.D., a Mayo Clinic nephrologist and senior creator of the research. “Additional validation can be wanted to find out the function of those markers in predicting cognitive decline.”
The researchers additionally noticed that increased ranges of those markers have been related to decrease volumes of whole grey matter of the mind, which is necessary for cognitive and mental features.
“The science of identification of circulating extracellular vesicles within the blood is quickly evolving for a lot of ailments,” says Sonja Suvakov, M.D., Ph.D., a Mayo Clinic postdoctoral analysis fellow in nephrology and first creator of the research.
“These vesicles facilitate intercellular transport and communication. In some ailments, manufacturing of extracellular vesicles will increase, together with a change of their content material, which is why they’re steadily seen as markers of cell harm. Future analysis is required to find out their significance within the context of cognitive decline related to a historical past of preeclampsia all through a lady’s life.”
The best way to Handle Preeclampsia Early?
For girls who’re pregnant, Dr. Garovic advises being conscious of preeclampsia indicators and signs:
- Attend prenatal visits so your well being care skilled can monitor your blood stress.
- Look ahead to sudden weight acquire and swelling. Whereas each are typical throughout wholesome pregnancies, sudden weight acquire or swelling, notably within the face and palms, could also be an indication of preeclampsia.

For these with a historical past of preeclampsia, it is necessary to share that data with their well being care skilled. “We encourage ladies to debate their reproductive historical past with their main care suppliers,” Dr. Garovic says.
“The understanding of girls’s future well being dangers associated to their reproductive historical past is continually advancing.”
