Sleep Apnea Linked to Increased Risk of Late-Onset Epilepsy in Elderly
Scientists note a link between sleep apnea and senile epilepsy, identifying populations with nighttime hypoxia, characterized by low oxygen levels during sleep.
United States: Medical frontline reports from the US show that sleep apnea actually gives a predisposition to late-life epilepsy at the elderly population level.
What is late-life epilepsy?
According to the US News reports, later-onset epilepsy is known as seizure activities, which appear to start in one’s body after reaching the age of 60.
Dr. Rebecca Gottesman, the study co-author and chief of the Stroke Branch at the National Institute of Neurological Disorders and Stroke (NINDS), said that the condition could be linked to underlying diseases related to the heart or brain.
Gottesman noted, “Compared to other age groups, older adults have the highest incidence of new cases of epilepsy — up to half of which have no clear cause,” as US News reported.
According to her, the connection between sleep apnea and poor brain health has long been established. However, the link between apnea and epilepsy is especially still “not well understood.”
The study was published in the journal Sleep, last year.
Know more about the study
The study examined data from over 1,300 participants who took part in a study of sleep-disordered breathing and heart disease.
According to NIH, the connection between epilepsy and the breathing disorders of sleep apnea was strong, where “People whose oxygen saturation fell below 80% during sleep, a condition known as nocturnal hypoxia, were three times more likely to develop late-onset epilepsy compared to those who did not have similarly low oxygen levels,” as US News reported.
Moreover, individuals who develop any form of sleep apnea later in life are more than two times more likely to be diagnosed with late-onset epilepsy compared to those without such histories.
Dr. Christopher Carosella, the study lead author also noted that the study was not made to answer questions such as ” Could getting sleep apnea under control (with, for example, use of a CPAP machine) help prevent late-onset epilepsy?” However, it is an interesting thought, said Carosella.
Carosella, who. is an assistant professor of neurology at Johns Hopkins University in Baltimore, said, “Discovering a reversible cause for the development of any type of idiopathic epilepsy is an aspirational goal for epilepsy researchers or clinicians,” as US News reported.
He added, “We hope this study might be a small first step in that direction and also an encouragement to evaluate and treat sleep disorders in patients with epilepsy.”
United States: As experts note, if one skips a workout or stays up late, his/her brain might still be paying for it even two weeks from now.
The team of researchers from Aalto University and the University of Oulu in Finland have presented how our lifelong daily behaviors influence brain connectivity and how they remain remodeled throughout our lifespan, thus providing valuable grounds for understanding neural plasticity.
More about the finding
Researchers are now very specific that the ways our brains communicate also change, rather than staying the same over a long time, in response to recent experiences over a long extended time period.
Moreover, they also rejected several principles of brain function stability and opened the consciousness of the influence of human daily habits on the neural network, studyfinds.org reported.
The particular experimental design of this study was examined in one subject over the span of five months and reported in PLOS Biology.

By acquiring a brain image every few days and integrating it with data donated by wearables and smartphones, the researchers were able to assess how such pre-mentioned variables as sleep quality, physical activity, mood, and even heart rate variability affect the connectivity of the brain.
Further details of the analysis
The participant, Ana Triana, was also the main researcher in the study and received thirty scans over fifteen weeks.
Each scan involved four different tasks: simple attention task, working memory task, resting state, and then execution of watching the movie.
This variation helped the researchers to trace how various types of brain activities changed along with everyday perceptions.
At the same time, monitoring devices of her sleep/wake cycle, physical movements, and data about her heart and breathing rates were collected.

The mobile application is used to capture the moods and events of each day. This integration of brain scans and actigraphy gave us an extremely high-resolution picture of how daily experience and brain activity were related, studyfinds.org reported.
The study revealed two distinct patterns of brain response: A brief wave, which lasts for a period of up to seven days, and a long-term wave, which can go up to fifteen days.
Results of the study
One of the interesting outcomes was a strong connection between heart rate variability – which is a measure of the heart’s adaptability – and brain connectivity while resting.
It shows that activities that affect our body’s relaxation response, like stress management ways, can shape our brain wiring even when we’re not actively concentrating on a task.
United States: Obesity remains a huge problem for Americans as far as their health is concerned. New data received by the governments indicate severe obesity, a condition that involves storing far too much fat in the body, has risen to a great extent in the last decade.
More about the study
About 40 percent of the population in the US is obese, according to a 2021-2023 survey of about 6,000 people.
Overall, 9 percent of those polled said they were suffering from severe obesity, according to the US Centers for Disease Control and Prevention (CDC).
Moreover, women were nearly two times as likely as men to report severe obesity.
The general obesity rate looked to have decreased in comparison to what was observed in the 2017-2020 survey. However, it was not considered as a statistically significant change.

That is, the numbers are small enough that there exists a probability that the rates did not fall at all.
What more are the experts stating?
Dr. Samuel Emmerich conducted the latest study for CDC as a public health officer. He said it is still early to determine its impact on the disease, including new obesity treatments, which include weight-loss drugs like Wegovy and Zepbound.
What they found is that the combined obesity estimate of the United States in the last decade has not considerably altered.
According to Emmerich, “We simply can’t see down to that detailed level to prescription medication use and compare that to changes in obesity prevalence.”
The prevalence of severe obesity increased from nearly eight percent in the study between 2013 and 2014 to nearly 10 percent in the most recent study.
Prior to that, obesity rates had risen rapidly in the US since the 1990s, according to US federal research.
🇺🇸 — Nearly 40% of Americans are obese, with cases of severe obesity rising sharply, particularly among women, who are nearly twice as likely as men to be severely obese. In 23 states, more than 1 in 3 adults were obese.

Obesity and severe obesity are expressed in terms of BMI, which is calculated with the help of height and weight. The above BMI indicates that a person is obese, as per the Food and Drugs Administration.
Super obesity is defined as the condition when the person’s BMI is 40 or more.
Solveig Cunningham is a professor of global health at Emory University who is interested in obesity.
“Seeing increases in severe obesity is even more alarming because that’s the level of obesity that’s most highly associated with some of the highest levels of cardiovascular disease and diabetes and lower quality of life,” Cunningham added.
Cunningham also added that it is not apparent why severe obesity rates were higher among women.
United States: Recent reports about potential health risks and whether fluoride benefits are as big as once believed have prompted scrutiny of a public health practice – adding fluoride to water supplies.
This is because, as with some questions, the safety of the practice and new data raise questions about the value of fluoride.
More about the news
Adding fluoride to tap water produces only a slight benefit in reducing tooth decay in children’s baby teeth, a new report from the Cochrane Collaboration, an independent group reviewing scientific research, finds.
It is found that adding fluoride to tap water is a slight benefit, leading to slightly fewer cavities in children’s baby teeth, CNN Health reported.
One step in the right direction is to rid our water of fluoride!It’s toxic poison… M.A.H.A. 🇺🇸🦅💯🙌🏻M.A.H.A. https://t.co/WPog4DfVma

More about the finding
Research done before 1975 had large benefits; children living in areas with fluoride added to their water averaged about one fewer primary teeth affected by decay than those of children living in areas without water fluoridation.
Those findings don’t apply to more current populations with increased access to other sources of fluoride and lower levels of dental disease at baseline.
Since the 1970s, fluoride-containing toothpaste has been widely available and is more often used.
According to the new report published this week, fluoride in water was tied to a difference in decay of only about a quarter of a tooth, on average, in more recent studies.
The federal judge, last month had asked the US Environmental Agency to further regulate fluoride in drinking water in response to concerns that fluoride may affect young children’s intellectual development, CNN Health reported.
In light of concerns about fluoride’s possible effect on young children’s intellectual development, a federal judge last month ordered that the EPA further regulate fluoride in drinking water.
Some foods and groundwater have fluoride, a mineral. It can help protect tooth enamel, which can erode with acids produced by plaque, bacteria, sugar, and other acids found in your mouth.
The USA began adding fluoride to public water systems in 1945.
Now, almost three-quarters of the US population, about two hundred and nine million people, are served by drinking water systems that have been fluoridated, according to data from the CDC.
