Tim Walz's son Gus has a nonverbal learning disorder. What is that?

After his heartfelt reaction to his father’s acceptance speech at the Democratic National Convention thrust him into the spotlight, 17-year-old Gus Walz has become one of the most high-profile people with nonverbal learning disorder.
The condition doesn’t mean Gus can’t speak — he does. After hearing his dad, Minnesota Gov. Tim Walz, describe his family as “my entire world” Wednesday night, the tearful teenager rose to his feet, pointed toward the stage and said, “That’s my dad!”
Gus is one of millions of Americans with nonverbal learning disorder. A 2020 study in JAMA Network Open estimated that 3% to 4% of children and adolescents in the U.S. may have the condition, and another study this year in Scientific Reports concluded that the prevalence in children may be as high as 8%.
The condition, known as NVLD, was first recognized in 1967 and doesn’t yet have a formal clinical definition. It is characterized by a significant gap between verbal abilities — which are just fine — and nonverbal kinds of learning that involve visual-spacial processing, such as telling time on an analog clock, reading a map and balancing a budget.
Those challenges with spacial awareness can give children trouble with motor skills. That can make them clumsy or cause problems with tasks like tying shoes, using silverware and writing by hand, according to the NVLD Project, a nonprofit that aims to have the condition added to the American Psychiatric Assn.’s Diagnostic and Statistical Manual of Mental Disorders.
In a way, having NVLD is like the opposite of having dyslexia, according to Scott Bezsylko, who works with neurodivergent students as executive director of Winston Preparatory School.
Reading is not a problem for kids with NVLD, who often have a large vocabulary. They’re also able to recall facts and memorize things like multiplication tables.
School becomes more challenging toward the end of elementary school, when learning becomes more about noticing patterns and applying concepts. That can cause problems with reading comprehension and more advanced kinds of math problems.
NLVD also affects higher-order thinking, which is used to organize our thoughts and plan a project that requires multiple steps.
Tim Walz and his wife Gwen told People magazine that they noticed differences between Gus and his classmates from an early age, and that those differences “became increasingly clear” as he grew older. The couple, both teachers, didn’t specify what those differences were.
Gus was recognized as having NVLD “when he was becoming a teenager,” the Walzes said, adding that he also has attention-deficit/hyperactivity disorder and an anxiety disorder.
It’s not uncommon for people with NVLD to have an ADHD diagnosis as well, according to the Child Mind Institute. Both conditions can make a child seem disorganized or inattentive; in the case of NVLD, it’s because they don’t understand the assignment being discussed.
Some features of NVLD also overlap with those of autism spectrum disorder. People with NVLD may be socially awkward because they don’t recognize the meaning behind facial expressions, body language and other nonverbal forms of communication. They may compensate by asking a lot of questions, which can come off as annoying.
Difficulty with visual-spacial processing can make it hard for those with NVLD to respect other people’s personal space. Plus, their challenges with pattern recognition give them trouble relating past experiences to new situations.
Traits like these can make it hard to make friends, experts say. That tracks with the Walzes’ experience.
“Gus preferred video games and spending more time by himself,” his parents told People.
Comedian Chris Rock said that when he learned as an adult that he had NVLD, it explained a lot of things from his past.
Although he’s great with words, “I kind of have a hard time with nonverbal cues with people. I always have,” Rock said in a 2021 interview with Extra. “They say 70% of communication is nonverbal. So my relationships, even with my family or women I dated or whatever, there was always something a little off, and I couldn’t put my finger on it.”
The causes of NVLD are not clear. Although the deficits associated with the condition involve processes that occur in the right hemisphere of the brain, studies sponsored by the NVLD Project that compared brain scans of people with and without the disorder found differences in both hemispheres.
Regardless, the condition does not affect intelligence, and people can learn strategies to compensate for their shortcomings.
Successful interventions can include practice taking a problem and breaking it up into manageable pieces, or looking for patterns in complicated texts. As their skills improve, they develop a library of “scripts” that can help them in new situations, according to the Child Mind Institute. If they don’t have a suitable script on hand, they’ll have experience with creating a new one.
The same approach may help people with NVLD get better at navigating social situations as well, experts say.
It seems the Walzes have taken this advice to heart.
“It took us time to figure out how to make sure we did everything we could to make sure Gus would be set up for success as he was growing up,” they told People.
Being neurodivergent means Gus “is brilliant [and] hyper-aware of details that many of us pass by,” the Walzes added. “What became so immediately clear to us was that Gus’ condition is not a setback — it’s his secret power.”

COVID and bird flu are rising. Here's how to keep yourself safe
![COVID and bird flu are rising. Here's how to keep yourself safe COVID and bird flu are rising. Here's how to keep yourself safe](https://ca-times.brightspotcdn.com/dims4/default/a27adb1/2147483647/strip/true/crop/6720x3528+0+476/resize/1200x630!/quality/75/?url=https%3A%2F%2Fcalifornia-times-brightspot.s3.amazonaws.com%2F3f%2F91%2Fb734cb9b40f0855df80a7d410029%2F1352026-me-0922-covid-vaccines-lynwood-gem-002.jpg)
With California’s COVID surge at very high levels, doctors are urging people who are experiencing respiratory symptoms to test themselves or see a medical professional who can check on their illness.
This is the worst COVID summer infection spike in California since 2022, according to wastewater data. There are a number of possible culprits for the surge. A series of punishing heat waves and smoke from devastating wildfires have kept many Californians indoors, where the disease can more easily spread. Most adults are also well removed from their last brush with the coronavirus, or their last vaccine dose — meaning they’re more vulnerable to infection.
But changes in the virus have also widened the scope of the surge.
Of particular concern is the rise of a hyperinfectious subvariant known as KP.3.1.1, which is so contagious that even people who have eluded infection throughout the pandemic are getting sick.
“This is a very large surge that we are seeing currently. This is starting to rival, really, what we saw this past winter,” said Dr. Elizabeth Hudson, regional chief of infectious diseases at Kaiser Permanente Southern California.
Coronavirus levels in Los Angeles County wastewater are continuing to rise, according to the most recently available data. And viral levels in California wastewater are at “very high” levels as defined by the U.S. Centers for Disease Control and Prevention.
Coronavirus levels in the state’s wastewater were down 3% when comparing the week that ended Aug. 10 with the prior week, a possible indication that levels are cresting — although it’s also possible that coronavirus levels will increase again. Seasonal viral levels in sewage are expected to peak at some point, but it won’t be clear until a few weeks of consistent declines are observed.
Here are some things that experts say you can do to keep yourself safe:
Get tested
Doctors are urging people dealing with respiratory illness symptoms — including healthcare providers — to seek testing.
Dr. Abraar Karan, an infectious diseases expert and epidemiologist at Stanford University, said confirmation of a COVID-19 diagnosis would help a patient get a Paxlovid prescription to help treat the illness, while confirmation of another illness, like the flu, could help a patient get a drug more targeted toward that ailment.
An initial negative test does not mean you don’t have COVID; doctors suggest testing for as long as five days after the onset of symptoms to determine whether a test turns positive.
More consistent testing at medical facilities also could help detection of unusual strains that epidemiologists want to track, such as bird flu.
Bird flu has attracted attention recently because of outbreaks in poultry and dairy cows, and there have been several recent human cases among dairy and poultry workers in the U.S., according to the CDC.
The rise of bird flu
Recent human cases of H5N1 bird flu have resulted in primarily mild symptoms, including conjunctivitis, also known as pink eye, Karan said.
But one reason doctors are closely monitoring the situation is that, in the decades in which we’ve been aware of bird flu infecting humans, some H5N1 strains have resulted in significant mortality rates.
According to the CDC, human infections with H5N1 virus, which have been reported in 23 countries since 1997, have resulted in severe pneumonia and death in about 50% of cases.
Now that we know bird flu has infected cows, and there’s cow-to-human transmission, that poses a potential problem.
“Cow udders have receptors in common with birds, and they also have receptors in common with humans, where these viruses bind,” Karan said.
“Now, with human flu season coming, you have the risk of what’s called viral reassortment, where a host can get infected with both bird flu and human flu at the same time, and those flus now start swapping genetic material,” Karan said. “This is kind of how swine flu happened [in 2009]. So this is where we’re really worried. It’s like a ticking time bomb of human flu season around the corner, and yet we still have this uncontrolled spread of bird flu in cows.”
Bird flu hasn’t resulted in sustained human-to-human transmission, nor caused a pandemic in humans, in recent times.
“But it’s one of those pathogens that’s high risk of mutating to a point of increasing transmissibility. And the pathogen has had high virulence based on historical cases. … It’s the risk of where it could go,” Karan said.
Tracking the spread
This illustrates why it can be important for patients to get tested. If a test shows that a person has the flu, subsequent screening — including genetic subtyping — could eventually determine whether it is bird flu. And that could help epidemiologists figure out how the bird flu may have spread and help doctors determine the best course of treatment.
Even if a case of bird flu results in mild symptoms, it’s important to diagnose it, Karan said, so the virus sample can be genetically analyzed and scientists can track where it jumped from animal to human, and potentially more aggressively treat the patient with antivirals.
“But imagine — that only happens if I even test that patient for flu at all,” Karan said.
Where bird flu stands in the U.S.
Since 2022, according to the CDC, there have been 14 reported human cases of H5 bird flu in the U.S., 13 of which have been reported since March 24. Of the 14, nine have been confirmed as H5N1.
Of the 14 cases of bird flu in humans, 10 followed exposure to poultry, and the remainder followed exposure to cows. All of the reported human cases have occurred in three states: Colorado, Michigan and Texas.
Nationally, there are 48 states with bird flu outbreaks in poultry and 13 with outbreaks in dairy cows.
Since 2022, more than 100 million birds in the U.S. have been reported to have been infected with bird flu, including commercial poultry, backyard or hobbyist flocks and wild aquatic birds; it’s the first detection of this type of flu virus in the U.S. since 2016.
Bird flu has been detected in wild birds in most counties of California, including all of Southern California and the San Francisco Bay Area, and most of the Central Valley.
Bird flu outbreaks — those involving commercial poultry facilities or backyard poultry and hobbyist bird flocks — in California have been reported in just one county in Southern California: San Diego County. Bird flu outbreaks have occurred in a number of counties in Northern and Central California, including Sacramento, Contra Costa, Fresno, San Francisco, San Joaquin, Stanislaus, Sonoma, Monterey, Placer, Merced and Marin counties.
As for bird flu infecting dairy cows, 13 states have reported outbreaks — Idaho, Wyoming, Colorado, New Mexico, Texas, Oklahoma, Kansas, South Dakota, Minnesota, Iowa, Michigan, Ohio and North Carolina. In the last month, outbreaks infecting dairy cows have affected five states: Idaho, Colorado, Texas, South Dakota and Michigan.
In May, there was a detection of bird flu in a live bird market in San Francisco, according to the California Department of Food and Agriculture. State officials urged people to separate poultry from wild birds if possible.
“Because of the recent case in California poultry production and epidemiologic evidence that this strain was introduced by wild birds, we ask that California producers move their birds indoors through December 2024,” the California Department of Food and Agriculture said in June.
Protecting family and friends
The CDC earlier this year eased COVID isolation guidance, given that the health impacts of COVID-19 are lower than they once were, thanks to the availability of vaccines, anti-COVID medicines and increased population immunity.
There are fewer people being hospitalized and dying, and fewer reports of complications such as multi-inflammatory syndrome in children.
Still, doctors say it remains prudent to take common-sense steps to avoid illness and spreading the disease to others, given that COVID still causes significant health burdens that remain worse than the flu. Nationally, since the start of October, more than 49,000 people have been reported to have died of COVID; by contrast, flu has resulted in at least 25,000 fatalities over the same time period, according to federal estimates, which will be updated later this year.
While the prevalence of long COVID has been going down, long COVID can still be a risk any time someone gets COVID.
Doctors are urging everyone to get up to date on vaccinations — particularly if patients are at higher risk of severe complications from COVID-19. An updated COVID-19 vaccination formula is expected to become available in a matter of week, and the CDC is urging everyone 6 months and older to get one dose of the updated vaccine.
In California, just 37% of seniors 65 and older have received the last updated COVID-19 vaccine that first became available in September.
It’s especially important that older people get at least one updated dose. Of the patients he has seen recently who had serious COVID, UC San Francisco infectious diseases specialist Dr. Peter Chin-Hong said none of them had gotten an updated vaccine in the last year.
Avoid sick people. Some who are infected might pass off their symptoms simply as a cold or allergies when it could be the start of a COVID-19 illness.
Test if you’re sick, and test repeatedly if your first test shows up as negative.
An initial negative test doesn’t mean you don’t have COVID; doctors suggest testing for as long as five days after the onset of symptoms to check whether a test turns positive.
Consider taking a rapid COVID test once a day for three to five consecutive days after the onset of cough-and-cold symptoms, Hudson said.
Doing so can help a person take measures to later isolate themselves and limit spread of the illness to others.
Masks are much less common these days but can still be a handy tool to prevent infection. Wearing a mask on a crowded flight or in a crowded indoor venue where people nearby are coughing can help reduce the risk of infection.
The best mask is one that is well-fitted and that you find comfortable wearing. The most protective are N95 respirators, followed by KN95 respirators and KF94s. Surgical masks offer more protection than cloth masks.
Have a plan to ask for Paxlovid if you become ill. Paxlovid is an antiviral drug that, when taken by people at risk for severe COVID-19 who have mild-to-moderate illness, reduces the risk of hospitalization and death.
And if you get Paxlovid, make sure to take the full five-day course of treatment. Don’t stop taking the drug halfway through the dose.
There are also other anti-COVID medications that are available, such as remdesivir, which is given intravenously, and molnupiravir, which is given orally, like Paxlovid.
- Stay away from others while sick
The CDC recommends people stay home and away from others until at least 24 hours after their respiratory viral symptoms are getting better overall and they have not had a fever without using fever-reducing medicine such as Tylenol or Advil. Previously, the CDC suggested people with COVID isolate for at least five days and take additional precautions for a few more days.
In terms of deciding when symptoms are getting better, what’s most important is “the overall sense of feeling better and the ability to resume activities,” the CDC says. A lingering cough by itself can last beyond when someone is contagious, the CDC said.
But the CDC also advises added precautions for five additional days to avoid infecting others, such as wearing a mask, opening windows to improve air circulation, washing hands often, keeping one’s distance from others and continuing to test. It’s possible for infected people to be contagious even after they feel better.
The Los Angeles County Department of Public Health suggests infected people who have symptoms get a negative test result before leaving isolation. The agency also suggests those who are infected — regardless of whether they have symptoms — wear a mask around others for 10 days after they start feeling sick or, if asymptomatic, their first positive test result. However, they can remove their mask sooner if they have two sequential negative tests at least one day apart.
The agency suggests staying away from the elderly and immunocompromised people for 10 days after you start to feel sick, or, if asymptomatic, after their first positive test result.
If patients recover and then get sick again, they may have COVID rebound and need to stay home and isolate from non-infected people in their household.

Algae here, alien life out there — Cal State L.A.-JPL partnership connects engineers to astrobiology

When Erika Flores applied for an internship at NASA’s Jet Propulsion Laboratory in 2014, she wasn’t quite sure if her undergraduate work in environmental science fit at a place known for work much farther afield.
“I wanted to fix our planet,” Flores said recently. “I didn’t really imagine myself studying outer space.”
Aggressive and impactful reporting on climate change, the environment, health and science.
Not only did she land the internship at the La Cañada Flintridge institution’s Origins and Habitability Laboratory, but her contribution there also launched an ongoing partnership between the civil engineering department at Cal State Los Angeles and a lab dedicated to understanding how life begins.
“I did not see myself in an astrobiology lab,” Flores said from her office at the Los Angeles County Sanitation Districts, where she has worked since 2023 as an engineering associate.
But as it turns out, understanding how microorganisms came to be in Earth’s water is valuable knowledge to those tasked with cleansing that supply today, her mentor at JPL said.
“There’s a lot of overlap between wastewater and astrobiology,” said Laurie Barge, a JPL scientist who co-leads the Origins and Habitability Laboratory with research scientist Jessica Weber. “Sounds weird, but it’s true.”

This symmetry between the biology of our home planet and more distant worlds has led to a partnership between Barge and Weber’s lab and that of Flores’ former advisor Arezoo Khodayari, an associate professor of civil engineering at Cal State L.A.
After nearly a decade of collaboration, Barge and Khodayari recently received a grant from NASA that will cover up to six internships in the lab for Khodayari’s students over the next two years.
The award is one of 11 that NASA’s Science Mission Directorate made to universities that have not traditionally been part of the pipeline that brings new scientists to the space agency.

“We are intentionally increasing equitable access to NASA for the best and brightest talents in our nation,” said Shahra Lambert, NASA senior advisor for engagement, in a statement.
The two scientists connected through Flores who, with Barge’s encouragement, decided to go for a master’s degree at Cal State L.A. during her Origins and Habitability Laboratory internship.
While Khodayari’s research in Cal State L.A.’s Environmental Sustainability and Pollution Control lab focuses on managing contaminants here on Earth, she and Barge immediately saw parallels with the Origins and Habitability lab’s exploration of the conditions that could give rise to life across the universe.
“The fate of these chemicals in an aqueous environment is relevant for both fields,” Khodayari said. “All of these different projects have chemistry in common.”
After the success of Flores’ internship, the two scientists started looking for ways to introduce planetary science to students who might not have considered it as part of their training, and lacked access to the tools necessary for sophisticated research.

Eduardo Martinez was studying for a master’s in civil engineering in 2018 when Khodayari called him into her office and asked if he’d be interested in working for JPL.
“I was kind of taken aback a little bit,” recalled Martinez, who was born in Mexico and grew up in Los Angeles. “I was like — ‘JPL? Like, the Jet Propulsion Laboratory?’ ”
He was hooked immediately. As a civil engineering student, Martinez had been interested in how phosphorus and nitrogen affect water quality, leading to algal blooms and low oxygen levels when discharged in high quantities into freshwater. During the internship, he was a lead author on a research paper with Barge, Khodayari and others on how nitrates react with iron compounds in aqueous environments.
His work at the Origins and Habitability lab showed him that the same elements also play a crucial role in forming and sustaining life, and thus are a key point of interest for NASA astrobiologists. “I had not made that link before, and it was just fascinating to see,” Martinez said.
The experience inspired him to pursue a doctorate in geoscience at the University of Nevada, Las Vegas. His research there focuses on how certain isotope compositions in clay minerals could indicate past life in samples brought back from Mars.

Since Flores’ initial crossover from environmental science to space, five Cal State L.A. students have done internships at the JPL lab. The NASA grant will speed up that pipeline, introducing more students to research opportunities that may not otherwise have crossed their paths.
This summer, interns Julia Chavez and Cathy Trejo donned goggles and white lab coats to inject fluids into an iron chloride solution. The experiment replicates the reaction between seawater and the stuff that comes up through hydrothermal vents — an energy source for life on Earth, and a possible mechanism by which organisms first developed here.
“Five or six years ago, I didn’t really envision myself in research,” said Chavez, who completed her master’s degree this year. “Being here, I couldn’t imagine a different path.”

How a dire shortage of video game consoles helped prove that gaming boosts mental health
![How a dire shortage of video game consoles helped prove that gaming boosts mental health How a dire shortage of video game consoles helped prove that gaming boosts mental health](https://ca-times.brightspotcdn.com/dims4/default/c7574b5/2147483647/strip/true/crop/5472x2873+0+388/resize/1200x630!/quality/75/?url=https%3A%2F%2Fcalifornia-times-brightspot.s3.amazonaws.com%2Fd7%2F73%2Fe19b3b954ac4bf5ba37c19c08af6%2Fadobestock-516290951.jpeg)
In the early days of the COVID lockdown, Hiroyuki Egami was desperate to get his hands on a Nintendo Switch.
He already had one of the handheld game devices, but he also had two sons who were old enough to fight over it. The only way to maintain the peace in his family’s Tokyo home was to acquire a second unit.
So many parents had the same idea that stores in Japan quickly sold out. When the gaming consoles were back in stock, retailers held lotteries to ensure that everyone who wanted to buy one had an equal chance to do so.
Egami, an economist at Nihon University in Tokyo, quickly recognized that the lottery system could double as a natural experiment and shed light on a question that had been on his mind for years: Are video games actually detrimental to players’ mental health?
“People usually say that video games are harmful and you should decrease the time your children are playing,” he said. “As a father, I’ve been wondering whether it’s true.”
And as a researcher, he said, he felt “a kind of responsibility” to examine the evidence.
Not long before, the World Health Organization stirred up controversy by adding a condition called gaming disorder to the International Classification of Diseases. The ailment describes people who are so consumed by video games that they’re unable to control their playing behavior — even when it puts their health, their relationships with family and friends, and their livelihoods in jeopardy.
The WHO’s action reinforced longstanding views that video games are dangerous. Yet market researchers estimate that more than 3 billion people around the world play video games, a figure that’s been growing steadily for years.
And while titles like “Grand Theft Auto” and “Call of Duty” regularly make the bestseller list, so do family-friendly ones like “Minecraft,” “Animal Crossing,” “Madden NFL” and “Mario Kart 8.”

“Parents should know” whether gaming is truly hazardous, Egami said. “Parents shouldn’t feel too much pressure which is not rational.”
Studies linking gaming to aggression, addiction, cognitive function and general well-being have produced inconclusive results. One reason is that it’s hard to tell, for instance, whether game play itself makes people feel isolated, or whether people who are isolated tend to gravitate toward video games.
The way to tease out cause and effect is to take a group of people and randomly assign some of them to play video games while keeping others game-free to serve as controls. If differences emerge between the otherwise similar cohorts, they may be attributed to the games.
But experiments like these don’t reflect the way people play video games in real life, Egami said. They typically ask college students to play a video game in a laboratory at an appointed time — a study design that, while practical, limits the value of the findings.
That’s why Egami seized upon the video game lotteries. By randomly selecting some would-be gamers to purchase consoles while leaving others empty-handed, retailers unwittingly had set up the equivalent of a clinical trial.
Egami swung into action. He designed a questionnaire and got it into the field as quickly as possible, worried that the shortages would be resolved before he could collect the necessary data.
“Luckily, I could gather my research team and start working on it,” he said.
Between 2020 and 2022, nearly 100,000 people completed Egami’s survey, including 8,192 who took part in a video game lottery. More than a third of the lottery participants were considered “hardcore gamers” who played for at least 90 minutes each day. In addition to game-playing habits, the survey gauged people’s psychological well-being and distress. It also asked about a host of socioeconomic factors, including age, sex, job and family structure.
After crunching all the numbers, the researchers found that purchasing either a Nintendo Switch or a Sony PlayStation 5 through a lottery led to measurable reductions in the recipient’s psychological distress, and that possessing and playing with either device improved the owner’s mental health.
In addition, being selected to buy a PS5 through a lottery boosted gamers’ sense of life satisfaction. So did owning the console and using it to play games, the researchers found. (The team did not have the data to determine whether the same was true for the Nintendo Switch.)
While the improvements in well-being were statistically significant, they weren’t necessarily large enough to be noticed by gamers, Egami said.
The magnitudes of the changes were calculated in terms of standard deviations, which are used in statistics to convey how tightly a group of data points is clustered together. Medical studies suggest that changes are perceptible if they exceed 0.5 standard deviations. By that measure, only the mental health boosts from possessing or playing with a Switch were large enough for gamers to notice.
The data also indicated that after three hours of gaming in a single day, devoting any additional time to playing video games resulted in diminished returns. But there was no amount of time beyond which gaming became “detrimental to mental well-being,” Egami said.
The findings were published Monday in the journal Nature Human Behavior.
While it’s difficult to interpret the exact size of the effects, they “seem large enough to be perceptible to the players themselves,” said Matti Vuorre, a psychological scientist at Tilburg University in the Netherlands who studies video games and other virtual environments. That “indicates a meaningfully large effect in my books,” and makes it more difficult to argue “that gaming is an overall risk” for the average player, he said.
Nick Ballou, a postdoctoral researcher at the Oxford Internet Institute who studies how gaming affects mental health, said he suspects the improvements in well-being “would be minor but perceptible for people.” Anything much larger would be implausible, he said, since “games are only a small part of what contributes to a thriving life.”
Neither Vuorre nor Ballou was involved in Egami’s research, but they collaborated on a 2021 study that documented a dramatic increase in gaming during the pandemic. That was particularly true for multiplayer games, which suggests they were not just a source of entertainment but an outlet for social connection.
“We have lots of evidence that people turned to games as a lifeline in the early part of the pandemic,” said Ballou, who conducted one such study in May 2020. He said he wouldn’t necessarily expect the upside to be as strong in a more typical situation.
Egami agreed that some of the mental health benefits his team documented were likely due to the unique circumstances of the pandemic. But he doesn’t think they’ve disappeared altogether now that regular life has resumed.
“I hope this will bring peace to the general public that enjoys video games,” Egami said.
