(Press-News.org) Seizures in newborns are one of the most frequent acute neurological conditions among infants admitted to neonatal care units. A study published in Developmental Medicine & Child Neurology indicates that newborns experiencing such neonatal seizures face an elevated risk of developing epilepsy.
For the study, investigators analyzed data on all children born in Denmark between 1997 and 2018, with the goal of comparing the risk of epilepsy in children with and without neonatal seizures.
Among 1,294,377 children, the researchers identified 1,998 who experienced neonatal seizures. The cumulative risk of epilepsy was 20.4% among children with neonatal seizures compared with 1.15% among children without. This indicates that 1 in 5 newborns with neonatal seizures will develop epilepsy.
Epilepsy was diagnosed before 1 year of age in 11.4% of children with neonatal seizures, in an additional 4.5% between 1 and 5 years, 3.1% between 5 and 10 years, and 1.4% between 10 and 22 years. Stroke, hemorrhage, or structural brain malformations in newborns, as well as low Apgar scores, were associated with the highest risks of developing epilepsy.
“Our study highlights that there are risk factors that may be used to identify infants for tailored follow-up and preventive measures,” said corresponding author Jeanette Tinggaard, MD, PhD, of Copenhagen University Hospital – Rigshospitalet. “Importantly, four out of five neonatal survivors with a history of neonatal seizures did not develop epilepsy, and we suggest future studies to explore a potential genetic predisposition.”

Do seizures in newborns increase children’s risk of developing epilepsy?

Does the brain produce estrogen to control appetite?
2025-02-19
Although a woman’s ovaries produce the most estrogen, various types of estrogen are also synthesized throughout different tissues in the body, including the brain’s neurons. New research in The FEBS Journal indicates that such neuroestrogens help suppress appetite.
Knowing that the enzyme aromatase is important for the production of estrogens, investigators depleted or knocked out the gene encoding aromatase in mice, so that the animals were unable to synthesize estrogens in a systemic or body-wide manner. These mice demonstrated increased food intake and body weight compared with their aromatase-expressing counterparts. Restoring aromatase expression specifically ...
Would the prohibition of menthol cigarettes cause more harm than good?
2025-02-19
New research published in Health Economics indicates that a national prohibition of menthol cigarettes in the United States could increase the number of people who attempt to quit smoking but also support an illegal menthol cigarette market.
For the research, 639 adult menthol smokers made hypothetical choices between menthol and non-menthol cigarettes, menthol and non-menthol e-cigarettes, and attempting to quit. Participants were presented with situations where menthol cigarettes and menthol e-cigarettes were described as either legal, prohibited but available under-the-counter and online from retailers who continue ...
What are the benefits and harms of aggressive blood pressure lowering in older adults with different characteristics?
2025-02-19
Results from the Systolic Blood Pressure Intervention Trial (SPRINT) have supported lower blood pressure targets among community-dwelling older adults with hypertension to reduce the risk of cardiovascular disease and early death, but intensive blood pressure lowering can also increase risks of developing acute kidney injury and experiencing dangerously low blood pressure. A recent analysis in the Journal of the American Geriatrics Society looked closely at the benefits and harms of intensive blood pressure lowering in patients with different characteristics.
The analysis found that nearly all older adults in SPRINT had a positive ...
Why is Japanese knotweed so highly invasive?
2025-02-19
Research published in New Phytologist provides insights into why the invasive plant Japanese knotweed is so successful at outcompeting native plants.
Japanese knotweed (Reynoutria japonica), which is native to eastern Asia and is a highly invasive plant species across Europe and North America, is known to damage infrastructure and ecosystems. By comparing growth and reproduction traits of introduced plants with native plants, investigators discovered that introduced plants had gained the ability to reproduce faster by clonal propagation, a method ...
How will China’s reformed standards strategy affect corporate labor employment?
2025-02-19
The Chinese government is phasing in reforms for many technical standards that shape the products and services used by consumers around the world. While China has primarily depended on unilateral government authority for developing its standard system, the reforms would also incorporate market economies. New research published in Contemporary Economic Policy examined the impact of these reforms on corporate labor employment.
The study’s findings indicate that comprehensive standardization reform facilitates an increase in corporate labor employment by reducing transaction costs, enhancing operational efficiency, and improving the financing environment. The most profound impacts ...
Make America Healthy Again agenda at risk with reduction in force across federal health agencies
2025-02-19
Staffing reductions across U.S. federal health agencies—including the Department of Health and Human Services (HHS), Centers for Disease Control and Prevention (CDC), Food and Drug Administration (FDA), National Institutes of Health (NIH), and Agency for Healthcare Research and Quality (AHRQ)—pose a significant threat to public health, according to the Society for Healthcare Epidemiology of America (SHEA). The dismissal of thousands of staff is a massive loss of expertise and interruption ...
Revolutionizing energy-efficient smart windows: A flexible dual-band electrochromic device with energy storage
2025-02-19
As global energy consumption continues to rise, buildings account for approximately 40% of total energy use, with nearly half of that dedicated to indoor thermal regulation (heating and cooling). Windows, being the primary pathway for energy exchange between the interior and exterior of buildings, contribute to 20-40% of energy loss. Developing energy-efficient smart windows that reduce energy consumption while maintaining natural lighting and aesthetic appeal has become a key strategy in sustainable building development.
Researchers from Nanjing University of ...
Using a data-driven approach to synthesize single-atom catalysts that can purify water
2025-02-19
All humans need clean water to live. However, purifying water can be energy-intensive, so there is great interest in improving this process. Researchers at Tohoku University have reported a strategy using data-driven predictions coupled with precise synthesis to accelerate the development of single-atom catalysts (SACs) for more robust and efficient water purification.
SACs are one of the most crucial catalysts. They play a pivotal role in enhancing efficiency in diverse applications including chemical industries, energy conversion, and environmental processes. ...
Repeated invasions shape NZ’s bird life
2025-02-19
New University of Otago – Ōtākou Whakaihu Waka research shows Aotearoa has been increasingly accepting new bird species from around the world since the start of the Ice Age, offering clues into future migration patterns.
Since the Ice Age drastically changed the Aotearoa landscape from widely forested to grass and shrubland, researchers set out to determine which of our living and recently extinct birds are a result of existing lineages that adapted to their environment tens of millions of years ago and which are the descendants of comparatively recent invaders.
Using mitogenome data from nearly all living and recently extinct New Zealand mainland bird species, researchers ...
Wild fish can recognize individual divers
2025-02-19
For years, scientific divers at a research station in the Mediterranean Sea had a problem: at some point in every field season, local fish would follow them and steal food intended as experimental rewards. Intriguingly these wild fish appeared to recognize the specific diver who had previously carried food, choosing to follow only them while ignoring other divers. To find out if that was true, a team from the Max Planck Institute of Animal Behavior (MPI-AB) in Germany conducted a series of experiments while wearing a range of diving gear, finding ...
