A Peek Inside the Brains of ‘Super-Agers’
  + stars: | 2024-04-29 | by ( Dana G. Smith | ) www.nytimes.com   time to read: +1 min
When it comes to aging, we tend to assume that cognition gets worse as we get older. For a little over a decade, scientists have been studying a subset of people they call “super-agers.” These individuals are age 80 and up, but they have the memory ability of a person 20 to 30 years younger. Most research on aging and memory focuses on the other side of the equation — people who develop dementia in their later years. A paper published Monday in the Journal of Neuroscience helps shed light on what’s so special about the brains of super-agers. The biggest takeaway, in combination with a companion study that came out last year on the same group of individuals, is that their brains have less atrophy than their peers’ do.

Read previewManagers are worried that using powerful generative AI tools like OpenAI's ChatGPT in the workplace might cut their salaries. Of those surveyed, 48% of managers reported that AI tools are a "threat to their pay" and will "fuel wage declines" across the country in 2024. In early March, Cognition unveiled Devin, the 'first AI software engineer' the startup claims could fix bugs and train AI models. Sixty-two percent of managers surveyed, according to Beautiful.ai, said their employees feel like AI could eventually put them out of their jobs. "There's no doubt that the implementation of AI tools has employees questioning their value to a company," according to the survey.

These are all clinically documented cases of sleep sex, or sexsomnia, part of a family of sleep disorders called parasomnias that include sleepwalking, sleep talking, sleep eating and sleep terrors. “There certainly can be legal consequences from the sexual behaviors, particularly with minors, and also with aggressive behaviors during sleep,” Schenck said. Also called OSA, obstructive sleep apnea is a serious sleep malady in which breathing stops for 10 seconds to two minutes many times per hour each night. “It’s the breath holding or apnea from the obstructive sleep apnea that triggers the arousal, typically in men, which then triggers the sexual behaviors in sleep,” Schenck said. “It’s so interesting, because a lot of people with stress become hyposexual, not interested in sex,” Schenck said.

Having a routine job with little mental stimulation during your 30s, 40s, 50s and 60s was linked to a 66% higher risk of mild cognitive impairment and a 37% greater risk of dementia after the age of 70, according to the study, when compared with having a job with high cognitive and interpersonal demands. Attending college, for example, reduced the impact of a repetitive job by about 60% but didn’t fully negate the risk. Routine jobs that were not classified as “cognitively protective” often involved repetitive manual and mental tasks, such as is typical of factory work and bookkeeping. “Most people in routine jobs in our sample included housekeepers, custodians, construction workers and mail carriers,” Edwin said. More cognitively demanding jobs were not based on routine tasks, even though repetition was required at times.

Asian elephants bury their dead, study suggests

CNN —Researchers in India have for the first time documented how Asian elephants bury dead calves. While African elephants are known to bury dead calves, this is the first time that the behavior has been documented in Asian elephants, study author Akashdeep Roy, a researcher at the Indian Institute of Science Education and Research (IISER), told CNN on Wednesday. A dead calf being dragged by an adult. This is the first time that calf burials by Asian elephants have been documented. Roy contests this theory, explaining that contusions on the backs of the dead calves show that they were dragged to their resting place by other members of the herd.

Delta-8 THC, or delta-8 tetrahydrocannabinol, is one of more than 100 chemical compounds found in the cannabis sativa plant. That’s at least one or two students in every average-sized high school class who may be using delta-8. Most of the participants were about 17 years old, so the study may not fully represent how many younger teens are using delta-8. There has been a general concern that the number of students using delta-8 has been growing, according to an editorial published Tuesday alongside this study. Calls to America’s Poison Centers about delta-8 products spiked 82% from 2021 to 2022, the group said in a recent report, with 3,358 exposures managed in 2022.

There are several useful methods to treat the condition, including fixing your sleep hygiene and engaging in cognitive behavioral therapy specifically for insomnia. What do you do on those nights where you just know sleep isn’t coming — or, at least, not without a fight? The condition affects a lot of people, but is often underestimated as a cause of insomnia, Paruthi said. Don’t let bed become a place associated with long stretches of stressing to get to sleep, said Salas, who is also a sleep neurologist at the Johns Hopkins Center for Sleep and Wellness. “The worst thing somebody with insomnia could do is stay in bed and not sleep,” she said.

Now Donald Trump is warning about this linguistic diversity, arguing that New York’s classrooms are overwhelmed by foreign students who speak obscure languages. “They have languages that nobody in this country has ever heard of,” Mr. Trump said, referring to migrants who have recently arrived. But why did Mr. Trump deem this “a very horrible thing,” and not a call to arms for more research and more language teachers? There are many practical benefits to be found in the knowledge, wisdom and poetry of the languages that immigrants bring with them. The presence of these languages and their speakers continually revitalizes the profound social experiment that is America.

Read previewAt a recent closed-door fundraiser, President Joe Biden had to rely on note cards prepped by his staff to provide donors with detailed answers on his policy. But since the advent of mass communication technology and, as a result, an increasing expectation of US leaders to make public addresses, presidents have long relied on note cards and teleprompters to face their constituents. Even US presidents who had the public reputation of being robust and nimble needed note cards, Kastor said. John F. Kennedy, who was able to keep his medical problems, including persistent back pain, hidden from the public, used note cards. Former President Donald Trump, who is now 77, has received flack for relying on note cards albeit for different reasons.

While everyone’s gait differs, you may develop an abnormal gait due to illness, injury, genetics, or issues with your legs or feet. What a gait analysis can uncover about your healthAssessing gait can predict gross motor delays in kids, fall risks in older adults and, when coupled with a cognition decline, the risk of dementia. “We’re looking at gait speed, cadence — the number of steps per minute — variability in gait speed and cadence, step length, the time both feet are spent on the ground, stance and more,” said Stephanie Wakeman, a physical therapist and OneStep’s director of clinical operations. But if you’re interested in a gait analysis to boost your athletic performance or prevent injury, you may have to pay out of pocket. “I would also love it if gait analysis was part of the recovery program for anybody who has knee, ankle or hip surgery,” Heiderscheit said.

What about diabetes, cancer, thyroid disease, high blood pressure or heart disease? Some of the questions might seem unexpected to those who don’t write about brain health. However, my risk of developing vascular dementia, the second most common type after Alzheimer’s disease, is elevated. "Such spikes cause brain inflammation, disrupt brain metabolism and increase shrinkage of the thinking part of the brain," Isaacson said. The National Institute on Aging currently supports nearly 500 active clinical trials on Alzheimer’s disease and related dementias.

The human brain has trouble pulling names out of stuffed memory banks on cue. But when are those and other verbal stumbles normal, and when might they be a sign of cognitive trouble? Former President Donald Trump, Biden's likely opponent in the November presidential election, has also.

How we change as we ageA decline in cognitive abilities is a normal part of healthy aging, said Dr. Emily Rogalski, Rosalind Franklin Professor of Neurology at the University of Chicago. A diagnosis of mild cognitive impairment is made clinically when cognitive difficulties become frequent and fall outside what is considered normal aging. “There’s not a whole lot of good evidence that there’s anything special about age 80 that leads to a drop-off” in cognitive abilities, Mather said. And they use cognitive tests, such as the Mini Mental Status Exam (MMSE) or Montreal Cognitive Assessment (MOCA), to assess performance in different cognitive areas. Although population-level data associates aging with cognitive decline, the actual manifestation of aging is very diverse on an individual level, Rogalski said.

Two verbal slip-ups in the last few days are again bringing the concerns about the president’s cognition to the forefront. A January NBC poll of 1,000 registered voters found that three quarters of all voters, including half of Democrats, had concerns about Biden’s physical or mental health. The White House did not immediately provide a response to this story. In last year’s physical, Biden’s physician said an “extremely detailed” neurologic exam found no findings that would be consistent with stroke, multiple sclerosis or Parkinson’s disease. As with his previous physical in 2021, the White House did not say whether Biden underwent any cognitive tests, which some doctors recommend for older adults.

Overall, just 5% of respondents would at all consider getting a chip in the next year. Men were more than three times as likely as women (13% vs 4%) to be down for a commercially produced brain chip eventually. All told, 19% of respondents who said they read Dune would get a commercially available brain chip, and 11% of respondents who said they read Dune would get one this year.
