Could Ozempic be used to treat addiction? Studies hint yes, but questions remain

Published

 on

The diabetes drug Ozempic has become a household name as a powerful weight-loss treatment. Its cousin Wegovy, specifically marketed for weight loss, contains the same active ingredient — semaglutide — and is similarly skyrocketing in popularity.

But some people say the drugs have helped them do more than lose weight — people struggling with addiction are reporting that the drug has caused them to completely lose interest in alcohol, drugs and even obsessive shopping habits, The Atlantic reported in May.

Though these anecdotes may seem random, they are actually supported by more than 20 years of research, experts told Live Science. Animal studies have found that drugs like semaglutide, which mimic a gut hormone called glucagon-like peptide 1 (GLP-1), seem to suppress drug-seeking behaviors. Other studies in humans have found that the drugs, called GLP-1 agonists, could help some people with alcohol use disorder drink less and people who smoke drop cigarettes.

However, animal studies are not always reliable in determining if a drug will work the same way in people, and formal clinical trials testing GLP-1 agonists as addiction treatments are ongoing. Yet, scientists have reason to be optimistic, with research pointing to the drugs’ effect on a major system in the brain involved in addiction: the reward pathway.

 

“Unfortunately, the translation [of new drugs] from animals to humans is always challenging,” said Dr. Lorenzo Leggio, a physician-scientist at the National Institutes of Health (NIH) who studies the effects of GLP-1 agonists on addiction. But he said scientists who study GLP-1 agonists “are definitely excited” about the drugs’ potential to help people with addiction.

As early as the 1980s, researchers recognized that GLP-1 wasn’t produced only in the gut but also in parts of the brain, specifically in a part of the medulla, or lower brain stem, according to a 1986 study. By the 2010s, researchers were beginning to conduct studies, like one from 2011, to investigate the role this hormone might play in the brain’s system of reward and motivation. This system is called the mesolimbic pathway or “reward pathway.”

Part of the medulla called the solitary nucleus, receives incoming sensory information from the body, like taste signals from the tongue, while brain cells with GLP-1 receptors in the mesolimbic pathway help determine if you like a taste and if you’d like to experience that taste again. During rewarding experiences, whether they come from a good taste or an addictive drug, structures in the mesolimbic pathway activate and send dopamine to a part of the brain called the nucleus accumbens.

This structure plays key roles in generating pleasurable sensations and motivating reward-seeking behaviors. However, it seems that rather than activating this system, GLP-1 imposes limits on it. The hormone, along with the artificial version of it found in drugs like semaglutide, limits the brain’s release of the neurotransmitter dopamine, often called a “happy chemical.”

Food, water, sweets and addictive drugs all  “cause a release of dopamine in the nucleus accumbens in the brain,” said Patricia “Sue” Grigsono, director of the Penn State Addiction Center for Translation. Binding to GLP-1 receptors, then, should reduce that dopamine response.

“Published data show that substances of abuse do not elicit that dopamine release when you have a GLP-1 agonist on board,” she said. A 2020 study found some evidence that GLP-1 agonists might do this by impacting dopamine transporters in a brain region called the striatum, a main interface in the brain’s reward system, though they only found this effect in rats, not in mice and humans.

Studies on animal behavior also support the use of GLP-1 agonists to combat addiction. Grigson has been involved with several studies with the same basic design: A mouse or rat is trained to expect a drug, like alcohol or heroin, to be administered in response to certain cues. When the animal gets the cues but not the drug, the ones given GLP-1 agonists are less persistent in trying to seek out the drug. Animals that receive a “relapse” dose of the drug after having it withdrawn are even less likely to seek it out, Grigson said.

A 2022 study Grigson co-authored showed that when given the GLP-1 agonist liraglutide, rats were less likely to seek out heroin in response to drug-associated cues, stress or a dose of the drug itself, which would also normally prompt further drug-seeking.

So far, tests of drugs like semaglutide for human addiction have been limited, but researchers have seen some promising results.

In a 2021 study, people who took a GLP-1 agonist called exenatide in addition to using a nicotine patch were more likely to successfully quit smoking than those who used only the patch. A 2022 study found that a weekly dose of exenatide reduced the number of heavy drinking days in people with alcohol use disorder and obesity, but it didn’t help participants of lower weights. Leggio said that researchers aren’t sure what might cause a result like this. One possibility, he said, is that some people with obesity have more overlap in their brains between the response to food and the response to addictive substances.

There are several ongoing clinical trials that may soon tell us more. Leggio and Grigson are both involved in such trials and are eagerly awaiting the results — Grigson said one of hers should conclude in a few months. She also said unpublished research, led by a student of hers, exploring how GLP-1 agonists affect the brain suggests they work to treat addiction in two ways: by lessening the brain’s reward associated with taking an addictive substance and by decreasing desire for the drug during withdrawal.

Although the stories from people who say semaglutide have helped them overcome addiction are encouraging, Leggio said, they are no substitute for actual research. Still, he appreciates the anecdotes.

“You cannot be a good physician-scientist if you don’t listen to your patients,” he said. “I’m excited for those people.”

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Pediatric group says doctors should regularly screen kids for reading difficulties

Published

 on

 

The Canadian Paediatric Society says doctors should regularly screen children for reading difficulties and dyslexia, calling low literacy a “serious public health concern” that can increase the risk of other problems including anxiety, low self-esteem and behavioural issues, with lifelong consequences.

New guidance issued Wednesday says family doctors, nurses, pediatricians and other medical professionals who care for school-aged kids are in a unique position to help struggling readers access educational and specialty supports, noting that identifying problems early couldhelp kids sooner — when it’s more effective — as well as reveal other possible learning or developmental issues.

The 10 recommendations include regular screening for kids aged four to seven, especially if they belong to groups at higher risk of low literacy, including newcomers to Canada, racialized Canadians and Indigenous Peoples. The society says this can be done in a two-to-three-minute office-based assessment.

Other tips encourage doctors to look for conditions often seen among poor readers such as attention-deficit hyperactivity disorder; to advocate for early literacy training for pediatric and family medicine residents; to liaise with schools on behalf of families seeking help; and to push provincial and territorial education ministries to integrate evidence-based phonics instruction into curriculums, starting in kindergarten.

Dr. Scott McLeod, one of the authors and chair of the society’s mental health and developmental disabilities committee, said a key goal is to catch kids who may be falling through the cracks and to better connect families to resources, including quicker targeted help from schools.

“Collaboration in this area is so key because we need to move away from the silos of: everything educational must exist within the educational portfolio,” McLeod said in an interview from Calgary, where he is a developmental pediatrician at Alberta Children’s Hospital.

“Reading, yes, it’s education, but it’s also health because we know that literacy impacts health. So I think that a statement like this opens the window to say: Yes, parents can come to their health-care provider to get advice, get recommendations, hopefully start a collaboration with school teachers.”

McLeod noted that pediatricians already look for signs of low literacy in young children by way of a commonly used tool known as the Rourke Baby Record, which offers a checklist of key topics, such as nutrition and developmental benchmarks, to cover in a well-child appointment.

But he said questions about reading could be “a standing item” in checkups and he hoped the society’s statement to medical professionals who care for children “enhances their confidence in being a strong advocate for the child” while spurring partnerships with others involved in a child’s life such as teachers and psychologists.

The guidance said pediatricians also play a key role in detecting and monitoring conditions that often coexist with difficulty reading such as attention-deficit hyperactivity disorder, but McLeod noted that getting such specific diagnoses typically involves a referral to a specialist, during which time a child continues to struggle.

He also acknowledged that some schools can be slow to act without a specific diagnosis from a specialist, and even then a child may end up on a wait list for school interventions.

“Evidence-based reading instruction shouldn’t have to wait for some of that access to specialized assessments to occur,” he said.

“My hope is that (by) having an existing statement or document written by the Canadian Paediatric Society … we’re able to skip a few steps or have some of the early interventions present,” he said.

McLeod added that obtaining specific assessments from medical specialists is “definitely beneficial and advantageous” to know where a child is at, “but having that sort of clear, thorough assessment shouldn’t be a barrier to intervention starting.”

McLeod said the society was partly spurred to act by 2022’s “Right to Read Inquiry Report” from the Ontario Human Rights Commission, which made 157 recommendations to address inequities related to reading instruction in that province.

He called the new guidelines “a big reminder” to pediatric providers, family doctors, school teachers and psychologists of the importance of literacy.

“Early identification of reading difficulty can truly change the trajectory of a child’s life.”
