Higher risk of ischemic stroke at young age after pregnancy complications

Preeclampsia and preterm birth linked to ischemic stroke before age 50

2025-08-06
(Press-News.org) The study examined over a thousand women aged 18 to 49. Of these, 358 had suffered an ischemic stroke. Researchers compared the pregnancy histories of these women with those of 714 women who had not experienced a stroke. The results showed that more than half of the women who had an ischemic stroke had experienced at least one complication during pregnancy. In the group without ischemic stroke, this was one-third. 

 

Women who had experienced a stillbirth were found to be nearly five times more likely to suffer an ischemic stroke. Preeclampsia—characterized by high blood pressure and protein loss through urine—was also clearly linked to an increased risk, as were preterm birth and gestational diabetes. These complications are often associated with vascular damage, such as atherosclerosis. 

 

‘Fortunately, the overall risk of stroke remains low’, emphasizes neurologist Frank-Erik de Leeuw of Radboudumc. ‘But we see that certain pregnancy problems can serve as an early warning. If doctors are aware of this medical history, they can start preventive care earlier.’ 

 

Cause 

This study does not determine the exact cause of the strokes, but several possible explanations exist. ‘Pregnancy places a tremendous strain on the body’, explains researcher and first author Esmée Verburgt. ‘If complications arise, it may indicate vulnerable blood vessels.’ Another possible explanation is that pregnancy itself and the development of the placenta may lead to vascular abnormalities, resulting in atherosclerosis, which could later cause a stroke. 

 

Prevention 

The researchers advocate physicians—such as general practitioners and gynecologists—to actively inquire about previous pregnancies. Current guidelines recommend screening women with a history of preeclampsia for cardiovascular disease starting at age 50. De Leeuw: ‘This study suggests we might need to start earlier, as there is a clearly elevated risk of cardiovascular disease.’ According to the researchers, this can be done easily, for example by measuring blood pressure once a year. 

 

Stroke: recognize the signs 

Stroke affects up to one in five people in some high-income countries and nearly one in two in low-income countries. It is the second leading cause of death worldwide. In the Netherlands, approximately 30,000 people have an ischemic stroke and over 50,000 people experience a TIA annually. 6000 people suffer from intracerebral hemorrhage. Signs that may indicate a stroke include a drooping mouth, slurred speech, and sudden weakness or paralysis of an arm.

Complicated pregnancies linked to higher risk of early stroke

2025-08-06
EMBARGOED FOR RELEASE UNTIL 4:00 P.M. ET, WEDNESDAY, AUGUST 6, 2025 MINNEAPOLIS – Experiencing complications during pregnancy is linked with a higher risk of stroke before age 50, according to a study published August 6, 2025, in Neurology®, the medical journal of the American Academy of Neurology. Researchers found female participants who had certain pregnancy complications were more likely to have an early stroke. These included preeclampsia, preterm birth, gestational diabetes, miscarriage and stillbirth. The study does not prove that pregnancy complications cause stroke. It only shows an association. “While the ...

American Society of Anesthesiologists hosts ANESTHESIOLOGY® 2025

CHICAGO – Older patients whose primary language is not English may be at greater risk for delirium after surgery in American hospitals. People who struggle with food insecurity or loneliness may be more likely to experience chronic pain after surgery. Fentanyl overdose deaths in older adults are rising at similar rates to younger people. When anesthesiologists lead preoperative care for hip fractures, patients get to the operating room faster and recover better. These findings and other timely research ...

Cockatoos perform 30 distinct dance moves and may combine them in unique ways

2025-08-06
Captive cockatoos have at least 30 different dance moves in their repertoire, including headbanging and body rolls, according to a study by Natasha Lubke at Charles Sturt University in Australia, and colleagues, publishing August 6, 2025 in the open-access journal PLOS One. The moves, of which 17 are newly identified, may be performed with or without music. Several species of parrot have been anecdotally observed dancing to music in captivity. Dancing results from complex brain processes including imitation, ...

Common patterns found among scientists with remarkable early-career citation success

2025-08-06
A new analysis of data on scientists with exceptional early-career success—according to a metric known as citation impact—has identified common characteristics among them, some of which could also be indicators of problematic or fraudulent behaviors. John Ioannidis of Stanford University, U.S., presents these findings in the open-access journal PLOS One on August 6, 2025. Citation impact reflects a scientist’s overall influence in their field, which depends, in part, on the number of ...

What’s in your pup’s bowl? Heavy metals, reveals 10-state survey

2025-08-06
Two-thirds of dogs tested in a recent survey consume higher-than-recommended levels of heavy metals in their drinking water, according to a study published August 6, 2025 in the open-access journal PLOS Water by Audrey Ruple from Virginia Tech, U.S., and colleagues. The survey, which focused on well water households in 10 states, uncovered 13 instances where arsenic, lead and copper tested above EPA-recommended levels.  Roughly 15 million U.S. households use private well water and are not protected by the EPA’s Safe Drinking Water Act, which regulates safety testing in drinking water. These households — and the canine companions inside — ...

Ocean sediments might support theory that comet impact triggered Younger Dryas cool-off

2025-08-06
Analysis of ocean sediments has surfaced geochemical clues in line with the possibility that an encounter with a disintegrating comet 12,800 years ago in the Northern Hemisphere triggered rapid cooling of Earth’s air and ocean. Christopher Moore of the University of South Carolina, U.S., and colleagues present these findings in the open-access journal PLOS One on August 6, 2025. During the abrupt cool-off—the Younger Dryas event—temperatures dropped about 10 degrees Celsius in a year or less, with cooler temperatures lasting about 1,200 years. Many researchers believe that no comet was ...

Toxic well water will affect household pets first, new study finds

2025-08-06
Dogs drink water wherever they happen to find it — a puddle, a pond, a toilet. But the stuff in their actual water bowls almost always comes from the same tap their owners use. When that water is contaminated, both dogs and humans may suffer. The risk is especially high for the 15 million American households that rely on private wells, according to a new Virginia Tech study in the journal PLOS Water. In dog drinking water sampled from wells across the country, 64 percent contained excessive levels of at least one potentially toxic heavy metal, such as lead, iron, sulfur, or arsenic.  Whatever’s ...

Some young suns align with their planet-forming disks, others are born tilted

2025-08-06
(Santa Barbara, Calif) — Researchers at UC Santa Barbara, The University of Texas at Austin, Yale University and National Taiwan Normal University have found that a fair number of sun-like stars emerge with their rotational axis tilted with respect to their protoplanetary disks, the clouds of gas and dust from which solar systems are born. “All young stars have these discs, but we’ve known little about their orientations with respect to the spin axis of the host stars,” said UCSB associate physics professor Brendan Bowler, who studies how planets form and evolve through their orbits and atmospheres, and is senior author of a study in ...
