By Gina Kolata Dr. John Q. Trojanowski, a neuropathologist whose work was at the forefront of research on Alzheimer’s and other neurodegenerative diseases, died on Feb. 8 in a hospital in Philadelphia. He was 75. His wife and longtime collaborator, Virginia M.-Y. Lee, said the cause was complications of chronic spinal cord injuries. Dr. Trojanowski “was a giant in the field,” said Leslie Shaw, a professor with Dr. Trojanowski in the department of pathology and laboratory medicine at the University of Pennsylvania — adding that he meant that in two ways. At 6 feet 4 inches, Dr. Trojanowski towered over his colleagues. And, Dr. Shaw said, he was also a towering figure in his field, whose scientific contributions were “phenomenal” because they combined pathology and biochemistry to figure out what goes wrong, and why, when people get diseases as disparate as Alzheimer’s, Parkinson’s and A.L.S. The results can lead to improved diagnosis and potential treatments. Key to the work Dr. Trojanowski did with Dr. Lee was their establishment of a brain bank: stored brains from patients with diseases like Alzheimer’s and Parkinson’s, as well as from people without degenerative brain diseases. It allowed them to compare the brains of people with and without the conditions and ask what proteins were involved in the diseases and what brain regions were affected. Among their first quests was an attempt to solve the mystery of strange areas in the brains of people with Alzheimer’s. Known as tangles and first described by Alois Alzheimer himself at the turn of the 20th century, they look like twisted strands of spaghetti in dying nerve cells. In 1991, Dr. Trojanowski and Dr. Lee determined that the regions are made up of a malformed protein called tau, which causes the structure of nerve cells to collapse. At a time when most Alzheimer’s researchers and drug companies were focused on a different protein, amyloid, Dr. Trojanowski and Dr. Lee insisted that tau was equally important. They then discovered that it also played a central role in a rare group of degenerative dementias known as frontotemporal lobar degeneration. © 2022 The New York Times Company

By Linda Searing Depression affects about 280 million people worldwide, including about 5 percent of all adults, according to data from the World Health Organization and a report from the World Psychiatric Association Commission, an international research group. The commission describes depression as “one of the leading causes of avoidable suffering and premature mortality in the world” and labels it a neglected global health crisis. FAQ: What to know about the omicron variant of the coronavirus In the United States, an estimated 21 million adults, or about 8 percent of those 18 and older, are living with depression, according to the National Institute of Mental Health. In addition, the Centers for Disease Control and Prevention note that roughly 11 percent of all physician office visits and emergency department visits are related to depression. Though most everyone feels sad or gloomy from time to time, depression — what the medical world refers to as depressive disorder or major depression — goes beyond simple mood fluctuations. Rather, such feelings as sadness, hopelessness or low self-worth, loss of interest in usual activities, sleep problems and lack of energy persist for two weeks or more, interfering with a person’s everyday life. Genetics, chemical changes in the brain and stressful events are among factors believed to be responsible for depressive episodes. Left untreated, depression can have devastating effects. But treatment — which may include such approaches as talk therapy, medication, exercise, light therapy or acupuncture — can ease symptoms and help prevent a recurrence. However, the World Psychiatric Association Commission report, published in the Lancet, notes that about half of people suffering from depression in high-income countries are not diagnosed or treated, a number that increases to as much as 90 percent of those with depression who live in low- and middle-income countries. © 1996-2022 The Washington Post

By Kim Tingley Denis Burkitt, an Irish surgeon, traveled to Africa during World War II as a member of the Royal Army Medical Corps, and afterward he settled in Uganda to practice medicine. There he observed that a surprising number of children developed strange jaw tumors, a cancer that would come to be known as Burkitt lymphoma. Eventually, Burkitt sent samples of the tumor cells to Middlesex Hospital Medical School in London, where Michael Anthony Epstein, a pathologist, and his colleagues Yvonne Barr and Bert Achong examined them through an electron microscope. Their findings — they noticed particles shaped like a herpesvirus, only smaller — were published in a landmark paper in The Lancet in 1964 and spurred the realization that this newly identified member of the Herpes​viridae family, subsequently named Epstein-Barr virus, was a cause of Burkitt lymphoma. It was the first evidence that a viral infection could lead to cancer. The virus has since been shown to increase the risk of Hodgkin lymphoma, as well as nasopharyngeal and stomach cancer. It is also the virus most often responsible for infectious mononucleosis, a disease usually characterized by extreme fatigue, sore throat, fever and swollen lymph nodes in the neck. These symptoms can last for weeks and, in chronic cases, recur for years. We now know that upward of 90 percent of adults have the Epstein-Barr virus. As happens with other herpes​viruses, once you have been infected, the virus stays with you forever — it deposits its DNA alongside yours in the nucleus of many of your cells. (RNA viruses, like SARS-CoV-2, can be cleared from your body.) Most people contract Epstein-Barr in childhood: It is spread through body fluids, usually saliva; kissing is a frequent route of transmission (as may be the sharing of utensils). Young children, if they get sick at all, typically develop symptoms indistinguishable from those of a cold or flu; mono is more common when the first infection happens after puberty. “Most people never know they’re infected,” says Jeffrey Cohen, the chief of the Laboratory of Infectious Diseases at the National Institute of Allergy and Infectious Diseases. © 2022 The New York Times Company

By Amanda Coletta Health officials in New Brunswick released a long-awaited report Thursday into a mysterious and debilitating neurological disorder that has struck dozens of people with bizarre symptoms — including a belief that family members have been replaced by impostors — stumped doctors and stoked fears across the province. The conclusion? There is no new disorder. “The oversight committee has unanimously agreed that these 48 people should never have been identified as having a neurological syndrome of unknown cause, and that based on the evidence reviewed, no such syndrome exists,” said Jennifer Russell, chief medical officer of health for the Canadian province. “Public Health concurs with these findings. But I stress again, this does not mean that these people aren’t seriously ill. It means they are ill with a known neurological condition.” The report’s authors say the 48 cases in what was thought to be a cluster were randomly allocated to pairs of neurologists who reviewed them and presented their findings to an oversight committee of six New Brunswick neurologists and other officials. The committee said none of the cases met the full criteria of the case definition. But that finding, coming at the end of an investigation marred by accusations of opacity from the start and allegations that Canada’s top scientists and experts from around the world had been abruptly shut out of the process, appeared unlikely to assuage alarm in the province and more likely to deepen mistrust. Patients and their family members questioned the committee’s findings Thursday, saying the province has not carried out the relevant testing and opted to “abandon scientific rigor in exchange for political expediency.” © 1996-2022 The Washington Post

By Maryam Clark, science writer Neuroscientists have recorded the activity of a dying human brain and discovered rhythmic brain wave patterns around the time of death that are similar to those occurring during dreaming, memory recall, and meditation. Now, a study published to Frontiers brings new insight into a possible organizational role of the brain during death and suggests an explanation for vivid life recall in near-death experiences. Imagine reliving your entire life in the space of seconds. Like a flash of lightning, you are outside of your body, watching memorable moments you lived through. This process, known as ‘life recall’, can be similar to what it’s like to have a near-death experience. What happens inside your brain during these experiences and after death are questions that have puzzled neuroscientists for centuries. However, a new study published to Frontiers in Aging Neuroscience suggests that your brain may remain active and coordinated during and even after the transition to death, and be programmed to orchestrate the whole ordeal. When an 87-year-old patient developed epilepsy, Dr Raul Vicente of the University of Tartu, Estonia and colleagues used continuous electroencephalography (EEG) to detect the seizures and treat the patient. During these recordings, the patient had a heart attack and passed away. This unexpected event allowed the scientists to record the activity of a dying human brain for the first time ever.

By David A. Kaplan Our cross-country drive last winter from New York to Lake Tahoe was going to be eventful enough, with a pandemic, blizzards and the cancellation of salads at McDonald’s. But by Omaha, when the lanes on Interstate 80 seemed to be bouncing around before my very eyes, we entered unexpected territory. “Are you practicing your slalom turns at 80 miles an hour?” my wife asked. Road conditions were normal. Our S.U.V. had new tires. But the lanes often seemed to blur together. Sometimes the melding of lanes occurred late in the day, sometimes early. Sometimes in blinding sun, sometimes in fog. If I closed one eye, the lanes became separate again. What was happening? I’d worn glasses for nearsightedness since fifth grade; I’d seen my eye doctor within the year; my prescription was current. When we reached Tahoe, I went to an optometrist before even unpacking my skis. She said my eyes were fine, but advised an M.R.I. to rule out a brain bleed or a tumor. Days later, it did. She also told me to see a neuro-ophthalmologist, an increasingly rare subspecialty. Nationally, there are only about 600 of them, and because many do academic research or have general ophthalmic practices, just 250 of them are full-time clinicians. In six states, there are none practicing, according to a paper in the Journal of Neuro-Ophthalmology last year. The Tahoe optometrist warned it could take months to obtain an appointment with one of the few practitioners in the area. But my brother, a surgeon at Stanford, helped me get an appointment at Stanford Medical Center, four hours away, in Palo Alto, Ca., the following week. Dr. Heather Moss conducted the 90-minute examination, taking measurements that included the degree to which my eyes were properly centered. © 2022 The New York Times Company

By Diana Kwon People with a rare genetic disorder known as Prader-Willi syndrome never feel full, and this insatiable hunger can lead to life-threatening obesity. Scientists studying the problem have now found that the fist-shaped structure known as the cerebellum—which had not previously been linked to hunger—is key to regulating satiation in those with this condition. This finding is the latest in a series of discoveries revealing that the cerebellum, long thought to be primarily involved in motor coordination, also plays a broad role in cognition, emotion and behavior. “We’ve opened up a whole field of cerebellar control of food intake,” says Albert Chen, a neuroscientist at the Scintillon Institute in California. The project began with a serendipitous observation: Chen and his team noticed they could make mice stop eating by activating small pockets of neurons in regions known as the anterior deep cerebellar nuclei (aDCN), within the cerebellum. Intrigued, the researchers contacted collaborators at Harvard Medical School. Scientists there had gathered data using functional MRI to compare brain activity in 14 people who had Prader-Willi syndrome with activity in 14 unaffected people while each subject viewed images of food—either immediately following a meal or after fasting for at least four hours. New analysis of these scans revealed that activity in the same regions Chen’s group had pinpointed in mice, the aDCN, appeared to be significantly disrupted in humans with Prader-Willi syndrome. In healthy individuals, the aDCN were more active in response to food images while fasting than just after a meal, but no such difference was identifiable in participants with the disorder. The result suggested that the aDCN were involved in controlling hunger. Further experiments on mice, conducted by researchers from several different institutions, demonstrated that activating the animals’ aDCN neurons dramatically reduced food intake by blunting how the brain’s pleasure center responds to food. The findings were recently detailed in Nature. © 2022 Scientific American,

Dominique Potvin When we attached tiny, backpack-like tracking devices to five Australian magpies for a pilot study, we didn’t expect to discover an entirely new social behaviour rarely seen in birds. Our goal was to learn more about the movement and social dynamics of these highly intelligent birds, and to test these new, durable and reusable devices. Instead, the birds outsmarted us. As our new research paper explains, the magpies began showing evidence of cooperative “rescue” behaviour to help each other remove the tracker. While we’re familiar with magpies being intelligent and social creatures, this was the first instance we knew of that showed this type of seemingly altruistic behaviour: helping another member of the group without getting an immediate, tangible reward. As academic scientists, we’re accustomed to experiments going awry in one way or another. Expired substances, failing equipment, contaminated samples, an unplanned power outage—these can all set back months (or even years) of carefully planned research. For those of us who study animals, and especially behaviour, unpredictability is part of the job description. This is the reason we often require pilot studies. Our pilot study was one of the first of its kind—most trackers are too big to fit on medium to small birds, and those that do tend to have very limited capacity for data storage or battery life. They also tend to be single-use only. A novel aspect of our research was the design of the harness that held the tracker. We devised a method that didn’t require birds to be caught again to download precious data or reuse the small devices. © 1986–2022 The Scientist.

Nicola Davis Science correspondent It may not yet feature in a West End musical but scientists say they have found an unexpected response to singin’ in the brain. Researchers say they have found particular groups of neurons that appear to respond selectively to the sound of singing. Writing in the journal Current Biology, a team of scientists in the US report how they made their discovery by recording electrical activity in the brains of 15 participants, each of whom had electrodes inserted inside their skulls to monitor epileptic seizures before undergoing surgery. The team recorded electrical activity in response to 165 different sounds, from pieces of instrumental music to speech and sounds such as dogs barking, and then processed them using an algorithm. They combined the results with data from fMRI brain scans previously collected from 30 different individuals to map the location of the patterns in the brain. Dr Samuel Norman-Haignere, a co-author of the study based at the University of Rochester, said the team decided to combine the data from the different approaches to overcome their respective weaknesses and combine their strengths. “fMRI is one of the workhorses of human cognitive neuroscience, but it is very coarse. Intracranial data is much more precise but has very poor spatial coverage,” he said. The results confirmed previous findings from fMRI scans that some neurons respond only to speech or respond more strongly to music. However, they also revealed populations of neurons that appear to respond selectively to the sound of singing, showing only very weak responses to other types of music or speech alone. © 2022 Guardian News & Media Limited

Brian Mann Over the next two weeks, some of the biggest U.S. corporations accused of "turbocharging" the opioid epidemic could finalize payouts to victims and governments worth roughly $32 billion. "We've lost more than a million Americans to this epidemic, and sadly, it's at an all-time high as overdose deaths continue to rise," said Texas Attorney General Ken Paxton last week, in a statement announcing his state is now in line to receive roughly $1.1 billion. Paxton said pharmaceutical companies that made, distributed and sold opioids were "at the root of the problem." Their payments will help fund "treatment for those currently still struggling with opioid addiction," he added. This comes as communities across the U.S. are scrambling for resources to combat an opioid crisis that keeps getting worse. Drug overdoses killed more than 104,000 Americans in the most recent 12-month period for which data is available, according to the Centers for Disease Control and Prevention. That's a tragic new record for the U.S. There are two major negotiations nearing completion. The largest involves major drug distributors and wholesalers AmerisourceBergen, Cardinal Health and McKesson, along with health products giant Johnson & Johnson.

by Laura Dattaro Some genomic areas that help determine cerebellar size are associated with autism, schizophrenia and bipolar disorder, according to a new study. But heritable genetic variants across the genome that also influence cerebellar size are not. The cerebellum sits at the base of the skull, below and behind the much larger cerebrum. It coordinates movement and may also play roles in social cognition and autism, according to previous research. The new work analyzed genetic information and structural brain scans from more than 33,000 people in the UK Biobank, a biomedical and genetic database of adults aged 40 to 69 living in the United Kingdom. A total of 33 genetic sequence variants, known as single nucleotide polymorphisms (SNPs), were associated with differences in cerebellar volume. Only one SNP overlapped with those linked to autism, but the association should be explored further in other cohorts, says lead investigator Richard Anney, senior lecturer in bioinformatics at Cardiff University in Wales. “There’s lots of caveats to say why it might be worth following up on,” Anney says. “But from this data alone, it’s not telling us there’s a major link between [autism] and cerebellar volume.” So far, cognitive neuroscientists have largely ignored the cerebellum, says Jesse Gomez, assistant professor of neuroscience at Princeton University, who was not involved in the work. The new study represents a first step in better understanding genetic influences on the brain region and its role in neurodevelopmental conditions, he says. “It’s a fun paper,” Gomez says. “It’s the beginning of what’s an exciting revolution in the field.” Of the 33 inherited variants Anney’s team found, 5 had not previously been significantly associated with cerebellar volume. They estimated that the 33 variants account for about 50 percent of the differences in cerebellar volume seen across participants. © 2022 Simons Foundation

By Ellen Barry A new book by Dr. Thomas P. Insel, who for 13 years ran the United States’ foremost mental health research institution, begins with a sort of confession. During his tenure as the “nation’s psychiatrist,” he helped allocate $20 billion in federal funds and sharply shifted the focus of the National Institute of Mental Health away from behavioral research and toward neuroscience and genetics. “I should have been able to help us bend the curves for death and disability,” Dr. Insel writes. “But I didn’t.” Dr. Insel, 70, who left N.I.M.H. in 2015, calls the advances in neuroscience of the last 20 years “spectacular” — but in the very first pages of his new book, he says that, for the most part, they haven’t yet benefited patients. His book, “Healing: Our Path From Mental Illness to Mental Health,” is not an indictment of the science to which he devoted much of his adult life. Instead, it chronicles failures in virtually every other element of our mental health system, including the ineffective delivery of care, the gutting of community health services and the reliance on police and jails for crisis services. It also calls out a paradox: that the United States, a country that leads the world in spending on medical research, also stands out for its dismal outcomes in people with mental illnesses. Indeed, over the last three decades, even as the government invested billions of dollars in better understanding the brain, by some measures, those outcomes have deteriorated. The country’s long spell without breakthrough treatments can be attributed, in part, to the complexity of the brain. Dr. Insel rose through the ranks at a time of optimism that advances in neurobiology would lead to new treatments, and as head of N.I.M.H., as he put it, he “bet big on genomics.” But 20 years later, he said the role that genes play in schizophrenia and bipolar disorder has proven to be extraordinarily complex. “Each of those variants that have been discovered just account for a tiny, tiny amount of risk, so in aggregate, they’re probably significant, but you have to put a hundred of them together,” he said. “So we started doing bigger and bigger studies to find smaller and smaller effects.” © 2022 The New York Times Company

By Matt Richtel During the pandemic, emergency rooms across the country reported an increase in visits from teenage girls dealing with eating and other disorders, including anxiety, depression and stress, according to new data from the Centers for Disease Control and Prevention. The report provides new detail about the kinds of mental health issues affecting a generation of adolescents. Mental health experts hypothesize that the pandemic prompted some youth to feel isolated, lonely and out-of-control. Some coped by seeking to have control over their own behavior, said Emily Pluhar, a pediatric psychologist at Boston Children’s Hospital and instructor at Harvard Medical School. “You take a very vulnerable group and put on a global pandemic,” she said. “The eating disorders are out of control.” In the C.D.C. study, the agency said that the proportion of eating disorder visits doubled among teenage girls, set off by pandemic-related risk factors, like the “lack of structure in daily routine, emotional distress and changes in food availability.” The agency said that the increase in tic disorders was “atypical,” as these disorders often present earlier, and are more common in boys. But the C.D.C., reinforcing speculation from other clinicians and researchers, said that some teenage girls may be developing tics after seeing the phenomenon spread widely on social media, notably on TikTok. “Stress of the pandemic or exposure to severe tics, highlighted on social media platforms, might be associated with increases in visits with tics and tic-like behavior among adolescent females,” the C.D.C. wrote. In a related report, the C.D.C. also said on Friday that the increase in visits for mental health issues occurred as emergency rooms reported sharp declines overall in visits during the pandemic. As compared with 2019, overall visits fell by 51 percent in 2020 and by 22 percent in 2021, declines that the agency attributed in part to families delaying care, and a drop in physical injuries from activities like swimming and running. © 2022 The New York Times Company

"I can't actually play a song," says Schneider, who suffered two serious brain injuries during nearly 22 years in the Marines. "But I can play chords to take my stress level down." It's a technique Schneider learned through Creative Forces, an arts therapy initiative sponsored by the National Endowment for the Arts, in partnership with the departments of Defense and Veterans Affairs. It's also an example of how arts therapies are increasingly being used to treat brain conditions including PTSD, depression, Parkinson's and Alzheimer's. But most of these treatments, ranging from music to poetry to visual arts, still have not undergone rigorous scientific testing. So artists and brain scientists have launched an initiative called the NeuroArts Blueprint to change that.

By Pam Belluck Social isolation, economic stress, loss of loved ones and other struggles during the pandemic have contributed to rising mental health issues like anxiety and depression. But can having Covid itself increase the risk of developing mental health problems? A large new study suggests it can. The study, published Wednesday in the journal The BMJ, analyzed records of nearly 154,000 Covid patients in the Veterans Health Administration system and compared their experience in the year after they recovered from their initial infection with that of a similar group of people who did not contract the virus. The study included only patients who had no mental health diagnoses or treatment for at least two years before becoming infected with the coronavirus, allowing researchers to focus on psychiatric diagnoses and treatment that occurred after coronavirus infection. People who had Covid were 39 percent more likely to be diagnosed with depression and 35 percent more likely to be diagnosed with anxiety over the months following infection than people without Covid during the same period, the study found. Covid patients were 38 percent more likely to be diagnosed with stress and adjustment disorders and 41 percent more likely to be diagnosed with sleep disorders than uninfected people. “There appears to be a clear excess of mental health diagnoses in the months after Covid,” said Dr. Paul Harrison, a professor of psychiatry at the University of Oxford, who was not involved in the study. © 2022 The New York Times Company

Linda Geddes A simple test could end years of uncertainty for people with relatively common neurological conditions, new research has found. Historically, obtaining a definitive diagnosis for conditions including Huntingdon’s disease and some forms of amyotrophic lateral sclerosis has been difficult, because, although the cause of the symptoms is genetic, knowing which test to carry out has resulted in delays of many years. Now, a new study suggests that whole genome sequencing (WGS) can quickly and accurately detect the most common inherited neurological disorders, and could be implemented in routine clinical practice with immediate effect. “It is very exciting because it opens up the vista of a test that could end the diagnostic odyssey for many patients,” said Prof Sir Mark Caulfield from Queen Mary University of London and former chief scientist at Genomics England. “This work paves the way for this to be implemented immediately within the NHS.” WGS is already offered to people in England with rare disorders or childhood cancers through the NHS Genomic Medicine Service. However, the technique wasn’t thought to work on people with ‘repeat expansion disorders’ caused by the insertion of short repetitive chunks of DNA into the genetic code – in some cases, stretching across long distances – because they can be difficult to quantify. Such disorders are relatively common, affecting around one in 3,000 people, and include neurodegenerative and movement disorders such as Fragile X syndrome, Huntington’s disease, Friedreich’s ataxia, and some forms of amyotrophic lateral sclerosis or frontal lobe dementia. © 2022 Guardian News & Media Limited

By Christina Caron When Chris Lawson began dating Alexandra Salamis, the woman who would eventually become his partner, he was “Mr. Super Attentive Dude,” he said, the type of guy who enjoyed buying cards and flowers for no reason other than to show how much he loved her. But after they moved in together in 2015, things changed. He became more distracted and forgetful. Whether it was chores, planning social events or anything deadline-driven — like renewing a driver’s license — Ms. Salamis, 60, had to continually prod Mr. Lawson to get things done. Invariably, she just ended up doing them herself. “I was responsible for nothing,” Mr. Lawson, 55, admitted. Ms. Salamis, who is not one to mince words, described that period of their relationship as “like living with a child,” later adding, “I hated him, frankly.” But when she brought up her frustrations, Mr. Lawson would become defensive. And as she continued to nag, she started to feel more like a parent than a partner, something they both resented. Then in 2019, at a friend’s suggestion, the pair read an article about how attention deficit hyperactivity disorder, or A.D.H.D., can affect romantic relationships. “We both kind of looked at each other and our jaws dropped,” Ms. Salamis said. The couple, who live in Ottawa, had discovered something millions of others have realized, often after years of conflict: One of them — in this case, Mr. Lawson — most likely had A.D.H.D., a neurodevelopmental disorder often characterized by inattention, disorganization, hyperactivity and impulsivity. When one or both members of a couple have A.D.H.D., the relationship typically has unique challenges, which are usually exacerbated when the disorder goes undiagnosed, experts say. Studies suggest that people with A.D.H.D. have higher levels of interpersonal problems than their peers do, and marriages that include adults with A.D.H.D. are more likely to be unsatisfying. Forums like the one found on the popular website A.D.H.D. and Marriage are often filled with stories of frazzled, emotionally spent spouses stuck in unhealthy, yearslong patterns. But if a couple makes a strong effort to learn more about the disorder, manage its symptoms and find more effective ways to communicate, they can revitalize their relationship. © 2022 The New York Times Company

By Conor Feehly There's a paradox in our ability to pay attention. When we are hyper-focused on our surroundings, our senses become more acutely aware of the signals they pick up. But sometimes when we are paying attention, we miss things in our sensory field that are so glaringly obvious, on a second look we can’t help but question the legitimacy of our perception. Back in 1999, the psychologist Daniel Simons created a clever scenario that poignantly demonstrates this phenomenon. (Test it yourself in less than two minutes by watching Simons’ video here, which we recommend before the spoiler below.) In the scenario, there are two teams, each consisting of three players, with one team dressed in black and the other in white. The viewer is asked to count how many passes the team in white makes throughout the course of the video. Sure enough, as the video ends, most people are able to accurately guess the number of passes. Then the narrator asks: But did you see the gorilla? As it turns out, someone in a gorilla suit slowly walks into the scene, in plain sight. Most people who watch the video for the first time and focus on counting passes completely overlook the out-of-place primate. It seems strange, given the viewer’s intent observation of the small field of view where the scene unfolds. Predictive Processing Neuroscientist Anil Seth offers an interesting explanation of this phenomenon in his book Being You: A New Science of Consciousness. Seth’s description draws from one of neuroscience’s leading theories of cognition and perception. © 2022 Kalmbach Media Co.

By Jan Hoffman The federal government on Thursday proposed new guidelines for prescribing opioid painkillers that remove its previous recommended ceilings on doses for chronic pain patients and instead encourage doctors to use their best judgment. But the overall thrust of the recommendations was that doctors should first turn to “nonopioid therapies” for both chronic and acute pain, including prescription medications like gabapentin and over-the-counter ones like ibuprofen, as well as physical therapy, massage and acupuncture. Though still in draft form, the 12 recommendations, issued by the Centers for Disease Control and Prevention, are the first comprehensive revisions of the agency’s opioid prescribing guidelines since 2016. They walk a fine line between embracing the need for doctors to prescribe opioids to alleviate some cases of severe pain while guarding against exposing patients to the well-documented perils of opioids. Dr. Samer Narouze, president of the American Society of Regional Anesthesia and Pain Medicine, an association of clinicians, praised the tone, level of detail and focus of the project. “It’s a total change in the culture from the 2016 guidelines,” he said, characterizing the earlier edition as ordering doctors to “just cut down on opioids — period.” By contrast, the new proposal “has a much more caring voice than a policing one, and it’s left room to preserve the physician-patient relationship,” added Dr. Narouze, chairman of the Center for Pain Medicine at Western Reserve Hospital in Cuyahoga Falls, OH. The 229-page document warns of addiction, depressed breathing, altered mental status and other dangers associated with opioids, but it also notes that the drugs serve an important medical purpose, especially for easing the immediate agony from traumatic injuries such as burns and crushed bones. In those instances when opioids seem the way to go, the recommendations said, doctors should start with the lowest effective dose and prescribe immediate-release pills rather than long-acting ones. © 2022 The New York Times Company

By Emma Yasinski By the time kids diagnosed with attention deficit hyperactivity disorder meet with clinical psychologist Mary O’Connor, they have often been taking multiple medications or unusually high doses of stimulants like Ritalin. “They may have had a trial of stimulants that worked initially,” she says, but when the effect waned, their physicians prescribed higher doses, sometimes to the point of toxicity. O’Connor researches fetal alcohol spectrum disorders at the University of California, Los Angeles, where she has provided both diagnosis and treatment to children exposed to alcohol in the womb. At one end of the spectrum sits fetal alcohol syndrome, characterized by facial abnormalities, growth problems, and intellectual disabilities. The other end of the spectrum is characterized by subtler symptoms, including poor judgement and impulsivity — in other words, what looks to many like ADHD. But experts say standard ADHD treatments often don’t work as well for children exposed to alcohol in-utero. And lack of awareness, a shortage of specialists, and social stigma have combined to limit families’ ability to receive an accurate diagnosis and support for FASD, a condition that is underdiagnosed in the United States and could affect between 1 and 5 percent of this country’s children. The lack of diagnoses, scientists say, stifles research on treatments and may even cloud data on therapies for other disorders.
