First-term finals are nearly upon us and sadly a disturbing percentage of high school seniors are abusing stimulants Adderall (dextroamphetamine) and Ritalin (methylphenidate), which are prescribed for Attention Deficit Hyperactivity Disorder (ADHD). These drugs increase alertness, attention, and energy the same way cocaine does—by boosting the amount of the neurotransmitter dopamine.
Even though these drugs are legal, they’re quite dangerous if not used properly. Taking high doses can cause irregular heartbeat, heart failure, or seizures. High doses of these stimulants can lead to hostility or feelings of paranoia. So, rather than popping pills, it’s a lot safer—and smarter—to boost your grades the old-school way: by studying.

The NIH’s All of Us Research Program is a historic effort to create an unprecedented research resource that will speed biomedical breakthroughs, transform medicine and advance health equity. To create this resource, we are enrolling at least 1 million people who reflect the diversity of the United States.
At the program’s outset, we promised to make research a two-way street by returning health information to our participant partners. We are now delivering on that promise. We are returning personalized health-related DNA reports to participants who choose to receive them.
That includes me. I signed up to receive my “Medicine and Your DNA” and “Hereditary Disease Risk” reports along with nearly 200,000 other participant partners. I recently read my results, and they hit home, revealing an eye-opening connection between my personal and professional lives.
First, the professional. Before coming to All of Us, I was a practicing physician and researcher at Vanderbilt University, Nashville, TN, where I studied how a person’s genes might affect his or her response to medications. One of the drug-gene interactions that I found most interesting is related to clopidogrel, a drug commonly prescribed to keep arteries open after a major cardiovascular event, like a heart attack, stroke, or placement of a stent.
People with certain gene variations are not able to process this medication well, leaving them in a potentially risky situation. The patient and their health care provider may think the condition is being managed. But, since they can’t process the medication, the patient’s symptoms and risks are likely to increase.
The impact on patients has been seen in numerous studies, including one that I published with colleagues last year in the Journal of Stroke and Cerebrovascular Disease . We found that stroke risk is three times higher in patients who were poor responders to clopidogrel and treated with the drug following a “mini-stroke”—also known as a transient ischemic attack. Other studies have shown that major cardiovascular events were 50 percent more common in individuals who were poor responders to clopidogrel . Importantly, there are alternative therapies that work well for people with this genetic variant.
Now, the personal. Reading my health-related results, I learned that I carry some of these very same gene variations. So, if I ever needed a medicine to manage my risk of blood clots, clopidogrel would not likely work well for me.
Instead, should I ever need treatment, my provider and I could bypass this common first-line therapy and choose an alternate medicine. Getting the right treatment on the first try could cut my chances of a heart attack in half. The benefits of this knowledge don’t stop with me. By choosing to share my findings with family members who may have inherited the same genetic variations, they can discuss it with their health care teams.
Other program participants who choose to receive results will experience the same process of learning more about their health. Nearly all will get actionable information about how their body may process certain medications. A small percentage, 2 to 3 percent, may learn they’re at higher risk of developing several severe hereditary health conditions, such as certain preventable heart diseases and cancers. The program will provide a genetic counselor at no cost to all participants to discuss their results.
To enroll participants who reflect the country’s diverse population, All of Us partners with trusted community organizations around the country. Inclusion is vitally important in the field of genomics research, where available data have long originated mostly from people of European ancestry. In contrast, about 50 percent of the All of Us’ genomic data come from individuals who self-identify with a racial or ethnic minority group.
More than 3,600 research projects are already underway using data contributed by participants from diverse backgrounds. What’s especially exciting about this “ecosystem” of discovery between participants and researchers is that, by contributing their data, participants are helping researchers decode what our DNA is telling us about health across all types of conditions. In turn, those discoveries will deepen what participants can learn.
Those who have stepped up to join All of Us are the heartbeat of this historic research effort to advance personalized approaches in medicine. Their contributions are already fueling new discoveries in numerous areas of health.
At the same time, making good on our promises to our participant partners ensures that the knowledge gained doesn’t only accumulate in a database but is delivered back to participants to help advance their own health journeys. If you’re interested in joining All of Us, we welcome you to learn more.

Opioid use disorders (OUD) now threaten the health and lives of far too many young and adult Americans. While getting treatment is a key first step to recovery, overcoming an opioid addiction often comes with brutal withdrawal symptoms, including bad bouts of insomnia that are often untreatable with traditional prescription sleep medications. These medications act as sedatives, making them unsafe for people in OUD recovery.
But now, researchers have found that an approved drug for insomnia that works differently than other sleep medications could offer some needed help for the sleeplessness that affects those overcoming an opioid addiction . The drug, known as suvorexant (Belsomra ®), was provided in a study to people during and immediately after tapering off opioids, and it allowed them to sleep significantly more during this week-long period. Suvorexant also helped to reduce their opioid withdrawal and craving.
This study, which received support from NIH’s Helping to End Addiction Long-term (HEAL) Initiative certainly offers promising news. The Food and Drug Administration (FDA) approved suvorexant to treat insomnia in 2014, and it is available for off-label use to help people overcoming an OUD.
The good news, however, comes with a major caveat. This early clinical trial had relatively small enrollment numbers, and larger studies are definitely needed to follow up and confirm the initial results.
The latest findings, published in the journal Science Translational Medicine, come from a team at Johns Hopkins University School of Medicine, Baltimore, led by Andrew Huhn. He and colleagues recognized sleep disturbances as a severe problem during recovery. They wondered whether suvorexant might help.
Suvorexant doesn’t actively sedate people like other sleeping medications. Suvorexant works by targeting orexin, a biochemical made in the brain that helps keep you awake . Interestingly, orexin signals also have been implicated in opioid withdrawal symptoms, sleep disturbances, and drug-seeking behaviors.
Thirty-eight people entered the Hopkins study, and 26 completed it. Their average age was about 40, with close to equal numbers of white and Black participants. Most were male, and all were undergoing supervised withdrawal treatment with buprenorphine/naloxone, which is used in combination as a medication-assisted treatment for OUD.
To find out if suvorexant helped, the researchers measured total sleep time nightly using wireless devices that recorded brain activity and movement in people taking either 20 milligrams or 40 milligrams of suvorexant versus a placebo. The researchers also used standard methods to assess symptoms of opioid withdrawal, along with suvorexant’s potential for abuse.
The data showed that people taking suvorexant over four days while tapering off opioids slept about 90 minutes longer per night on average. They also continued to sleep for an extra hour a night on average in the four days following the tapering period. The researchers note that these increases in sleep duration far exceed the American Academy of Sleep Medicine’s threshold for clinically meaningful improvement.
The researchers also didn’t see any differences in adverse events between those taking suvorexant versus a placebo. They also note that the main side effect of suvorexant in general is feeling sleepy the next day as the drug wears off slowly. There also wasn’t any evidence that suvorexant might come with a risk for drug abuse.
However, because the study was small, it lacked the needed statistical power to determine meaningful differences between the two doses of suvorexant. The study also didn’t include many women. But overall, the evidence that suvorexant or even other medications that target orexin could improve OUD treatment appears quite promising.
The NIH’s HEAL Initiative has launched over 600 research projects across the country. These studies cover a range of science and health care needs. But a common thread running through these projects is a desire to enhance the evidence base for lifesaving OUD interventions. Another is a commitment to discover better ways to help people recover from an OUD, and these latest data on suvorexant show this commitment in action.

By 2050, the World Health Organization estimates that more than 700 million people—or one in every 10 people around the globe—will have disabling hearing loss. In the United States alone, hearing loss affects an estimated 30 million people . Hearing loss can be frustrating, isolating, and even dangerous. It is also associated with dementia, depression, anxiety, reduced mobility, and falls.
Although hearing technologies, such as hearing aids, have improved, not everyone has equal access to these advancements. In fact, though hearing aids and other assistive devices can significantly improve quality of life, only one in four U.S. adults who could benefit from these devices has ever used one. Why? People commonly report encountering economic barriers, such as the high cost of hearing aids and limited access to hearing health care. For some, the reasons are more personal. They may not believe that hearing aids are effective, or they may worry about a perceived negative association with aging. .
As the lead federal agency supporting research initiatives to prevent, detect, and treat hearing loss, NIH’s National Institute on Deafness and Other Communication Disorders (NIDCD) conducts and funds research that identifies ways to break down barriers to hearing health care. Decades of NIDCD research informed a recent landmark announcement by the Food and Drug Administration (FDA) creating a new category of over-the-counter (OTC) hearing aids. When the regulation takes effect (expected in 2022), millions of people who have trouble hearing will be able to purchase less expensive hearing aids without a medical exam, prescription, or fitting by an audiologist.
This exciting development has been on the horizon at NIDCD for some time. Back in 2009, NIDCD’s Working Group on Accessible and Affordable Hearing Health Care for Adults with Mild to Moderate Hearing Loss created a blueprint for research priorities.
The working group’s blueprint led to NIDCD funding of more than 60 research projects spanning the landscape of accessible and affordable hearing health care issues. One study showed that people with hearing loss can independently adjust the settings  on their hearing devices in response to changing acoustic environments and, when given the ability to control their own hearing aid settings, they were generally more satisfied with the sound of the devices than with the audiologist fit .
In 2017, the first randomized, double-blind, placebo-controlled clinical trial comparing an over-the-counter delivery model  of hearing aids with traditional fitting by an audiologist also found that hearing aid users in both groups reported similar benefits. A 2019 follow-up study  confirmed these results, supporting the viability of a direct-to-consumer service delivery model. A small-business research grant funded by NIDCD led to the first FDA-approved self-fitting hearing aid.
Meanwhile, in 2016, NIDCD co-sponsored a consensus report from the National Academies of Sciences, Engineering, and Medicine (NASEM). The report, Hearing Health Care for Adults: Priorities for Improving Access and Affordability, which was developed by an independent expert panel, recommended that the FDA create and regulate a new category of over-the-counter hearing devices to improve access to affordable hearing aids for adults with perceived mild-to-moderate hearing loss. These devices will not be intended for children or for adults with more severe hearing loss.
In sum, this targeted portfolio of NIDCD-funded research—together with the research blueprint and the NASEM consensus report—provided a critical foundation for the 2021 FDA rule creating the new class of OTC hearing aids. As a result of these research and policy efforts, this FDA rule will make some types of hearing aids less expensive and easier to obtain, potentially improving the health, safety, and well-being of millions of Americans.
Transforming hearing health care for adults in the U.S. remains a public health priority. The NIH applauds the scientists who provided critical evidence leading to the new category of hearing aids, and NIDCD encourages them to redouble their efforts. Gaps in hearing health care access remain to be closed.
The NIDCD actively solicits applications for research projects to fill these gaps and continue identifying barriers to care and ways to improve access. The NIDCD will also continue to help the public understand the importance of hearing health care with resources on its website, such as Hearing: A Gateway to Our World video and the Adult Hearing Health Care webpage.
