    Climate chaos demands reforms – Editorials

    EDITORIAL: During his recent visit to flood-ravaged Toba Tek Singh in Punjab, Finance Minister Muhammad Aurangzeb affirmed that the climate and agricultural emergencies declared by the prime minister last week would be fully leveraged to not just rehabilitate the affected communities, but also to confront the root causes and long-term consequences of such disasters.

    While he pledged swift measures to mitigate the immediate impact of flooding, such as curbing the hoarding of essential goods to prevent artificial shortages, inflation and their cascading effects, he rightly stressed that it is equally, if not more, vital to ensuring sustained investments in preparedness and structural reforms that can shield vulnerable populations from future crises.

    The minister hit the nail on the head when he remarked that “we must reflect on the self-inflicted pains, such as poor zoning laws and inappropriate land use for housing societies and crop cultivation that exacerbate the damage from natural disasters”. Any agri-climate emergency, therefore, must go beyond immediate relief and rehabilitation measures, and prioritise the addressing of reckless, ill-planned urban expansion and unsustainable agricultural practices, which have deepened ecological vulnerability and left communities increasingly exposed to climate shocks.

    Our cities require nothing less than a comprehensive overhaul of zoning frameworks, construction standards and building codes, with strict enforcement to safeguard both public welfare and the health of ecosystems.

    The unchecked construction of housing societies and commercial ventures on natural waterways, river banks and on storm-water drains has resulted in losses worth billions, exposing the unbridled greed driving such projects, and the incompetence and complicity of authorities who chose to turn a blind eye to these encroachments.

    Media reports have noted, for instance, that the Punjab irrigation department had long designated certain areas in Lahore as “flood-prone”. Yet widespread regulatory violations enabled the extensive construction of private housing schemes in these zones, leading to much devastation after the recent rains. The rules governing such projects are routinely flouted, applied selectively or, in some cases, don’t deem encroachments and constructions on or near natural waterways as illegal at all.

    Even in the case of illegal encroachments, it must be noted that these do not occur in isolation. They are connected to the wider city infrastructure, indicating the tacit involvement of multiple government departments. The core issue, therefore, lies in the government’s failure to enforce its own laws.

    What is urgently needed, therefore, is the strict implementation of existing zoning and land-use regulations, alongside new legislation where gaps remain. Equally important, the practice of granting discretionary waivers to illegal constructions by competent authorities must be brought to an end. Finally, vital urban infrastructure — storm-water drainage, pumping stations and emergency response systems — must be strengthened as their inadequacy, particularly in cities like Karachi, turns heavy downpours into urban catastrophes.

    Equally urgent is the need to address devastation in rural areas. In Punjab alone, around 1.3 million acres of farmland remains submerged, much of it in low-lying tracts, floodplains and riverbeds. As with our cities, the remedy is similar: step aside and let the water flow where it must.

    Cultivation on riverbeds should never have been permitted, and as has been noted in this paper recently, these areas ought to serve as natural recharge zones for groundwater and soils. Farmers must be incentivised to vacate floodplains; and, at the very least, cultivation there must be banned during the high-risk months between June and September.

    What Pakistan ultimately needs is a complete paradigm shift, wholly rethinking at a granular level how we build our cities and cultivate our lands to align with nature’s rhythms. Blaming high-emission countries for the climate-induced plight we find ourselves in is insufficient. Global accountability matters, but without fixing our own failures, our people and land will continue to be ravaged by climate disasters.

  • Dortmund on lookout for leaders as familiar cracks emerge

    Dortmund on lookout for leaders as familiar cracks emerge

    BERLIN, Sept 19 — Borussia Dortmund’s early promise is already being eroded by familiar failings in crucial moments just three games into the Bundesliga season.

    Dortmund, who host Wolfsburg on Sunday, have already shown a worrying tendency of fading late this season.

    Leading 3-1 in their season opener at St Pauli with five minutes remaining, Dortmund conceded twice in three minutes and lost rookie centre-back Filippo Mane to a red card.

    In the Champions League on Tuesday, Dortmund led three times away at Juventus — including 4-2 in the third minute of stoppage time — before allowing the Italians to snatch a 4-4 draw with two late goals.

    Dortmund’s lack of leadership was also evident when striker Serhou Guirassy and defender Ramy Bensebaini openly tussled when both wanted to take a late penalty, forcing coach Niko Kovac to intervene.

    Many of the same criticisms have been levelled at Dortmund in recent seasons: a team with talent and promise undermined by a lack of maturity.

    Dortmund were united in identifying the root of the problem in the aftermath of Tuesday’s game.

    Sporting director Sebastian Kehl said his side were “a bit naive in the last minutes,” adding “to give away a sure victory right at the end is a bitter result.”

    Dortmund goalkeeper Gregor Kobel told reporters: “We need to finish the game cooly and with composure — we have to play more maturely.”

    If Dortmund are to respond, there is probably no better opponent than their bunnies, Wolfsburg, a team they have had the better of for a decade.

    Dortmund have a remarkable recent record against the Wolves, particularly at home, where they have not lost since 2012.

    In their past four home games against Wolfsburg, Dortmund have won 4-0, 1-0, 6-0 and 6-1.

    Wolfsburg’s hopes of overturning the recent record could be boosted by the likely debut of Christian Eriksen.

    The 33-year-old former Tottenham and Manchester United midfielder said Thursday he was “fit and ready,” to play on Sunday.

    “If you ask me, then yes. The coach picks the team and decides who’s ready for the game — but I’m all set.”

    One to watch: Luis Diaz (Bayern Munich)

    Lost amid Harry Kane’s incredible run and Nicolas Jackson’s drawn-out transfer saga has been the form of another one of Bayern Munich’s former Premier League stars: Luis Diaz.

    Diaz has slotted in perfectly on Bayern’s left wing since arriving from Liverpool, scoring three goals and setting up two more in just three Bundesliga matches.

    After Bayern’s 3-1 win over Chelsea on Wednesday, the 28-year-old Colombian revealed he held talks with Barcelona in the summer, but made “an objective decision about my future” to move to Munich.

    “I’m very happy with my decision to join this great club. There were talks, which is normal in the transfer market, but I made the decision to come here and now I’ll try my best.”

    Key stats

    2 – Just three matchdays in, two coaches have already been sacked: Bayer Leverkusen’s Erik ten Hag and Borussia Moenchengladbach’s Gerardo Seoane. The two sides face off on Sunday.

    36 – Since last losing to Wolfsburg at home in 2012, Dortmund have won 10 and drawn two against the Wolves, scoring 36 goals and conceding just five.

    0 – Heidenheim are the only side yet to claim a point this season. They play away at fellow strugglers Hamburg on Saturday. — AFP

  • Mohammad Nabi stopped, told about Wellalage’s father’s death: ‘He passed away in middle of match, but SL informed later’

    Mohammad Nabi stopped, told about Wellalage’s father’s death: ‘He passed away in middle of match, but SL informed later’

    Afghanistan all-rounder Mohammad Nabi was left shocked after he was informed about Dunith Wellalage’s father’s death after the end of the Asia Cup Group B match at the Sheikh Zayed Stadium in Abu Dhabi. The crucial match for Afghanistan ended in a loss for the Rashid Khan-led side; however, Nabi was the standout performer, scoring 60 runs off 22 balls, including five sixes in the final over bowled by SriLanka’s Wellalage.

    Now the visuals have emerged of Nabi being informed about the same by a few journalists outside the venue. The senior Afghanistan all-rounder sported a worried look on his face as he expressed his condolences.

    Here’s how the conversation went between Nabi and a few journalists outside the Sheikh Zayed Stadium in Abu Dhabi:

    Reporter: Dunith Wellalage’s father passed away.

    Nabi: Father? How?

    Reporter: Heart attack. Just after the match.

    Nabi: Really?

    Reporter: The news came in the middle of the match. But he was told after the match was over.

    Nabi: Heart attack?

    Reporter: Yes, heart attack.

    Afghanistan crash out of the Asia Cup

    Afghanistan, viewed as a dark horse for the Asia Cup 2025, crashed out of the eight-team tournament after losing to Sri Lanka by six wickets. Charith Asalanka chased down the target of 170 with eight balls to spare as Kusal Mendis and Kamindu Mendis remained unbeaten on 74 and 26, respectively.

    With this win, Sri Lanka topped Group B, and the side will next take on Bangladesh in the Super 4s match at the Dubai International Stadium on Saturday.

    Speaking about Wellalage, the spinner had a bad day at the office, conceding 49 runs in four overs. He was smacked for 32 runs in the final over of the innings as Nabi smashed five sixes, helping Afghanistan post a respectable total on the board.

    Wellalage returned with just one wicket as he dismissed Ibrahim Zadran for 24 in the 13th over of Afghanistan’s innings.

  • Late-night show hosts decry suspension of Kimmel’s show: ‘Blatant assault on freedom of speech’ | Jimmy Kimmel

    Late-night show hosts decry suspension of Kimmel’s show: ‘Blatant assault on freedom of speech’ | Jimmy Kimmel

    Late-night show hosts Stephen Colbert, Jon Stewart, Seth Meyers and Jimmy Fallon and former host David Letterman have all rallied behind Jimmy Kimmel following ABC’s decision to indefinitely suspend his popular late-night show after his comments about the rightwing activist Charlie Kirk.

    In his opening monologue on Thursday night, Stephen Colbert mocked executives at Disney, ABC’s parent company, for caving to threats from Brendan Carr, the FCC chairman, when they pulled Kimmel off the air.

    In an excerpt posted on Instagram before broadcast, Colbert also scolded Carr for calling Kimmel’s commentary on the rush to politicize Kirk’s murder an affront to community values. “Well, you know what my community values are, Buster?” Colbert asked. “Freedom of speech.”

    “People across the country are shocked by this blatant assault on the freedom of speech,” Colbert added. He poked fun at Disney executives, saying: “As one source at ABC put it, they were pissing themselves all day” over the threat of Trump’s administration’s retaliation against the network. “On the bright side, that proves Disney is No 1 in streaming,” he joked.

    This article includes content provided by Instagram. We ask for your permission before anything is loaded, as they may be using cookies and other technologies. To view this content, click ‘Allow and continue’.

    In a separate video, the Late Show lampooned ABC parent company Disney, adapting a song from its animated hit Beauty and the Beast. In a message to employees at Disney, ABC, ESPN and Hulu, character Lumière’s lyrics in the song Be Our Guest were changed to say “shut your trap, we are warning you to cut the crap”.

    “Patriotically obedient host” Jon Stewart, meanwhile, stepped in to present “the all-new, government-approved Daily Show”, which he normally only hosts on Mondays. On a newly gold set – to match the Oval Office’s new aesthetic – Stewart struck a playfully sycophantic tone,

    Referring to Trump’s comment overnight that “Kimmel is not a talented person”, Stewart joked that Trump had a “Talent-O-Meter” to measure when a performer’s “niceness to the president goes below a certain level.”

    “At which point, the FCC must be notified to threaten the acquisition prospects for billion dollar mergers of network affiliates. These affiliates are then asked to give ultimatums to the even larger mega corporation that controls the flow of state approved content, or the FCC can just choose to threaten those licenses directly. It’s basic science. Read your Constitution!” he said to applause.

    Highlighting Donald Trump Jr and House speaker Mike Johnson criticising their political opponents for calling Trump’s administration “fascist”, Stewart played clips of Trump calling Democrats “fascists”, “animals” and “demonic”.

    In response to comments by Republicans that politically motivated violence was no laughing matter after Kirk’s death, Stewart showed clips of Republicans and conservatives mocking the 2022 hammer attack on house speaker Nancy Pelosi’s husband Paul Pelosi, which left him with a fractured skull.

    Stewart then interviewed the Filipino Nobel Peace prize-winning journalist Maria Ressa who was jailed in the Philippines in 2020 for her journalism criticising former president Rodrigo Duterte, who she said “collapsed our institutions in six months.”

    “Do you think it is weird it has taken Trump eight [months]?” Stewart asked.

    “I think he did it in the first 100 days,” Ressa replied, describing Trump’s dismantling of institutions that could stand up to his rule as “identical” to what happened in the Philippines.

    The NBC late-night host Seth Meyers made light of fears that he might be next in line to be canceled, starting his show on Thursday by pausing to say that as “[Trump’s] administration is pursuing a crack down on free speech … completely unrelated, I just want to say before we get started here that I’ve always admired and respected Mr Trump”.

    As his audience laughed, Meyers continued: “I’ve always believed he was – no, no, no – a visionary, an innovator, a great president, an even better golfer. And if you’ve ever seen me say anything negative about him, that’s just AI.”

    In his opening monologue, Jimmy Fallon joked, “I woke up to 100 messages from my dad saying, ‘sorry they cancelled your show’.”

    “To be honest with you all, I don’t know what is going on. And no one does. But I do know Jimmy Kimmel and he is a decent, funny and loving guy, and I hope he comes back,” he said to applause.

    Earlier on Thursday, veteran TV host David Letterman also condemned ABC’s decision while speaking at a festival for the Atlantic magazine.

    “I feel bad about this because we all see where this is going,” Letterman said. “It’s managed media. And it’s no good. It’s silly. It’s ridiculous. And you can’t go around firing somebody because you’re fearful or trying to suck up to an authoritarian criminal administration in the Oval Office. That’s just not how this works.”

    The statements come amid growing criticism against big media companies such as ABC and Paramount over their decisions to cancel popular shows including The Late Show with Stephen Colbert earlier.

    Trump has repeatedly accused mainstream networks of unfair coverage. Speaking on Air Force One on Thursday, Trump claimed – without providing evidence – that “97% [of major US networks are] against me”, adding: “Again, 97% negative, and yet I won easily. I won all seven swing states … They give me only bad press. I mean they’re getting a license. I would think maybe their licenses should be taken away.”

    Such show cancellations have been widely regarded as part of a broader trend where major media companies, eager to protect their business interests, are increasingly aligning with rightwing views supported by Trump. This shift, which reflects a growing chill across media networks, has drawn criticism from the public and Democratic lawmakers who feel the media is becoming more submissive to Trump’s White House at the expense of free speech.

    The controversy began after Kimmel, in a recent broadcast, suggested that “many in Maga land are working very hard to capitalize on the murder of Charlie Kirk”. Within a day, Carr condemned the comments as “truly sick” and suggested ABC could face regulatory consequences.

    The blowback on ABC and Disney on Thursday was swift, and ABC executives are reportedly hoping to find a way to bring Kimmel back soon.

    On Thursday, Reuters reported that Bob Iger, the Disney CEO, and Dana Walden, Disney Entertainment co-chair, agreed to take Kimmel’s show off the air on Wednesday and find a way to bring him back later, after struggling to agree on how to address the social media furor that erupted over Kimmel’s comments about Kirk.

    Reaction to Kimmel’s monologue had reached a fever pitch on Wednesday, including death threats that raised concerns for the safety of Kimmel and his staff, a source familiar with the matter told Reuters. The late-night host was prepared to make a statement, but Kimmel and Disney representatives could not find language that they agreed would not further inflame the situation.

  • Submarine cable cuts slow internet

    Submarine cable cuts slow internet


    ISLAMABAD:

    The Ministry of Information Technology informed the National Assembly Standing Committee on IT on Thursday that internet speed in Pakistan has slowed due to submarine cables being cut off the coast of Yemen.

    According to the ministry, telecom companies have shifted bandwidth to alternative routes, but restoration may take four to five weeks.

    During the meeting chaired by MNA Syed Aminul Haque, IT and Telecom Secretary Zarrar Hashim Khan said that not one or two, but four to five submarine cables had been severed near Yemen.

    “Two of the cables supplying Pakistan have been affected, forcing companies to divert bandwidth to alternate routes. Repairing such cables requires special ships, and full restoration could take a month,” he added.

    The committee was told that three new submarine cables would become operational within 12 to 18 months, linking Pakistan directly with Europe. Agreements for these cables have already been signed.

    The committee’s session was held at the Islamabad IT Park, where members raised concerns over internet disruptions. Committee member Sadiq Memon questioned why problems persist if three new cables are already planned.

    The secretary reiterated that multiple cable cuts off Yemen had created a serious situation and Pakistan’s connectivity was directly impacted.

    Briefing the committee on the Islamabad IT Park project, the IT secretary said the technology park is being built with South Korean funding through a $78 million loan extended in 2017.

    The loan carries a 10-year grace period and is to be repaid over 30 years at a concessional 0.5% markup.

    The park aims to boost exports by attracting IT companies and is being constructed to international standards. Both Islamabad and Karachi IT parks are being developed with Korean assistance.

    However, committee members expressed anger over repeated delays in the project and directed the ministry to issue a letter of displeasure to the Korean company handling construction.

    The company said that heavy rains before the project’s start, the dollar crisis that halted imports for six months, and high duties and taxes had all caused setbacks. The firm had repeatedly requested exemptions from duties and taxes.

    The project director revealed that nine project managers had been changed within 13 months, further complicating progress. The committee chair pressed the company on whether the park would be completed by the October 31 deadline.

    The Korean representatives admitted that the deadline could not be met, though most work would be finished by December 31, with commissioning expected by February 2026.

    Haque warned that if the October 31 deadline was missed, another letter of displeasure would be issued and the company could even be blacklisted. He said the deadline must be honored, and instructed the ministry to decide on further action against the company in early November if delays persist.

  • [World Alzheimer’s Day] Samsung Research Advances Early Detection of Alzheimer’s With Everyday Digital Data – Samsung Global Newsroom

    [World Alzheimer’s Day] Samsung Research Advances Early Detection of Alzheimer’s With Everyday Digital Data – Samsung Global Newsroom

    Alzheimer’s disease dementia, the most common form of dementia, accounts for an estimated 60 to 70% of cases worldwide. As the global population 65 and older grows rapidly, the number of patients is increasing just as quickly. To underscore the importance of Alzheimer’s care and raise awareness, the World Health Organization and Alzheimer’s Disease International designated September 21 as World Alzheimer’s Day.

     

    Ahead of World Alzheimer’s Day, Samsung Newsroom is highlighting Samsung Research’s ongoing work on the early detection of dementia.

     

     

    The Importance of Early Diagnosis

    Alzheimer’s disease is incurable and irreversible. Once symptoms appear, cognitive function declines steadily — disrupting daily life in profound ways.

     

    Mild cognitive impairment (MCI), often considered a precursor to dementia, is of particular concern. Clinical tests reveal measurable cognitive decline in those with MCI, yet they remain capable of performing daily activities. According to studies cited by the Alzheimer’s Association, about 12 to 18% of people 60 and older live with MCI, and 10 to 15% of them progress to dementia each year. As a result, early detection and management of MCI has become a growing priority in the medical community.1,2

     

     

    Multiple studies show that changes in the brain can begin 10 to 20 years before the onset of Alzheimer’s Disease Dementia.3 Therefore, detecting these early signs is critical. While recent advances in therapies have raised hopes for treatment, early diagnosis combined with ongoing care remains the most effective approach today.

     

     

    The benefits of early detection include:

     

    • Implementing lifestyle modifications — such as enhancing diet, engaging in exercise and promoting cognitive stimulation — to help delay disease progression.
    • Starting drug and non-drug interventions earlier to preserve cognitive abilities
    • Gaining access to new therapies including newly approved or trial-stage drugs

     

     

    Tracking Change Through Digital Biomarker Technology

    Smartphones and wearables have become essential in daily life, capturing detailed information about users’ habits and behaviors. Device data captures subtle routine changes with remarkable high sensitivity.

     

    Recognizing this potential, researchers at Samsung Research developed digital biomarker technology that tracks changes in cognitive function by analyzing multimodal data from smartphones and wearables — including app usage, typing speed, messaging patterns, call frequency, sleep and voice.

     

    Researchers proposed that digital biomarkers could measure symptoms of cognitive decline identified in prior studies. By analyzing multimodal smartphone and wearable data, they estimated cognitive states, confirming that digital biomarker algorithms effectively track cognitive changes.

     

    Recalling and repeating short sentences can evaluate short-term memory-related brain regions, while assessing speech fluency and accuracy reveals the state of language ability. Likewise, the regularity and variety of app and messaging use, along with call frequency, can offer insights into social networks and the brain’s executive functions.

     

    In short, the study demonstrated that brain regions responsible for language and short-term memory — typically impaired by Alzheimer’s disease — can be assessed through voice data. The findings also indicate that declines in social and behavioral abilities are associated with patterns of app use, messaging and call frequency.

     

     

    Detecting Decline With Everyday Data

    In July, the Samsung Research team presented studies on smart device–based technologies for detecting cognitive decline at the International Conference of the Institute of Electrical and Electronics Engineers’ (IEEE) Engineering in Medicine and Biology Society (EMBS) in Copenhagen, Denmark.

     

    One study introduced technology that analyzes smartphone keyboard input patterns to detect early signs of cognitive impairment. The research prioritized analyzing nonverbal features like typing speed and correction patterns over examining user input to minimize privacy risks. The language-independent approach demonstrated significant global potential, and the paper ranked within the top 7% of papers presented at the conference.

     

    Another study analyzed data from smartphones and Galaxy Watch sensors to monitor walking patterns — including gait speed, stride length and balance — for early detection of cognitive decline.

     

    Both studies demonstrate performance comparable to hospital-based dementia screening tests by leveraging everyday behavioral data, eliminating the need for additional user input, and showcasing the potential to track cognitive changes through routine data.

     

     

    Improving Quality of Life Using Technology

    Digital biomarker technology is designed to improve the early detection of subtle signs of Alzheimer’s Disease that might otherwise go unnoticed in daily life. Samsung Research plans to continue validating the performance of its digital biomarker models while further advancing the technology.

     

    Although continued collaboration with academia and the medical field is required for further refinement and improved accuracy, advances in early detection of dementia are anticipated to improve personal health, enhance quality of life and alleviate pressure on healthcare systems. Further research with academia and the medical community is needed for validation and enhanced accuracy, but ongoing advancements in this technology are expected to enhance personal health and quality of life while reducing the strain on healthcare systems.

  • Soccer Headers Damage Brains Even Without Concussions, Large Study Finds : ScienceAlert

    Soccer Headers Damage Brains Even Without Concussions, Large Study Finds : ScienceAlert

    The world’s most popular sport is reckoning with serious health concerns.

    The largest study of its kind has now found that repetitively heading a soccer ball can negatively impact the brain, even in amateur players who don’t report concussions.

    Among 352 amateur adult soccer players, those who took more than a thousand headers a year showed microscopic changes to the outer wrinkles of their brains, right behind their eyes, regardless of their age or sex.

    These players also performed slightly but significantly worse on memory and learning tests.

    “What’s important about our study is that it shows, really for the first time, that exposure to repeated head impacts causes specific changes in the brain that, in turn, impair cognitive function,” explains neuroscientist Michael Lipton at Columbia University.

    Lipton’s lab has been leading research on how soccer heading impacts the brain for over a decade now.

    Contact sports, like American football, Australian rules football, and rugby, are also contending with the downsides of repetitive head trauma, but in these cases, the discussion is often framed as a concussion crisis typically reserved for professionals.

    Lipton’s research at Columbia University suggests that even mild bumps to the head can add up, and it’s not just professional athletes or those who report concussions who are affected.

    Previous studies by Lipton have shown alterations to white matter among amateur soccer players compared to swimmers. Meanwhile, other studies have found white matter changes even without a history of concussion. But linking these brain changes to clear alterations in cognitive function has proven tricky.

    frameborder=”0″ allow=”accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share” referrerpolicy=”strict-origin-when-cross-origin” allowfullscreen>

    Lipton and his team have now developed a novel method that detects damage in the outermost wrinkles of the brain – a tricky spot to study using diffusion magnetic resonance imaging (dMRI).

    This layer is called the cortical gray matter–white matter interface (GWI), and until recently, not much was known about it.

    Using their new imaging technique, Lipton and his team scanned the brains of amateur soccer players, who had played for at least five years and within the last six months.

    Those who said they took more headers showed significant changes in the GWI at the front of their brains – a spot consistent with the trajectory of a soccer ball during a header.

    The authors suspect that this injury site reflects a contrecoup force – a sort of bruise to the brain that occurs on the opposite side of the skull.

    Injuries to the GWI may have gone undetected or underestimated in other imaging studies, which is possibly why there are conflicting results on the neurological impact of soccer headers.

    A graduate student in Lipton’s lab, Joan Song, developed a way to characterize what they were seeing in the MRI scans.

    “In healthy individuals, there’s a sharp transition between these tissues,” Song explains. “Here, we studied if an attenuation of this transition may occur with minor impacts caused by heading.”

    Sure enough, the boundary between white and grey matter was fuzzier in those who took more headers.

    “It’s very strong evidence that these microstructural changes are likely to be a cause of cognitive deficits,” Lipton says.

    Further investigation is needed, but the findings suggest that the GWI is a good place to image in future studies on soccer heading impacts.

    It may even be associated with disorders like chronic traumatic encephalopathy (CTE).

    The study was published in JAMA Network Open.
