Anxiety and Depression Associated With the Dependent Use of Generative AI in Medical Students: Cross-Sectional Study
Background: The growing integration of artificial intelligence (AI) in higher education has transformed learning processes but also raised concerns about potential mental health risks. Medical students represent a particularly vulnerable group due to high academic stress and increasing reliance on generative AI tools for study and decision-making tasks. Despite this, the relationship between AI dependence and psychological distress remains underexplored in Latin American contexts. Objective: This study aimed to evaluate the association between generative AI dependence and levels of stress, anxiety, and depression among medical students. Methods: A cross-sectional study was conducted with 187 human medicine students from a Peruvian university during the first academic semester of 2025. The Dependence on Artificial Intelligence Scale and the Depression, Anxiety, and Stress Scale–21 were applied. Negative binomial regression models, both crude and adjusted for sex, age, income, and year of study, were used to assess associations, reporting rate ratios (RRs) and 95% CIs. Results: Participants had a median age of 22 (IQR 19‐24) years, and 58.8% (110/187) were female. The median Dependence on Artificial Intelligence Scale score was 10 (IQR 7‐14). Generative AI dependence showed significant correlations with anxiety (ρ=0.336, 95% CI 0.22‐0.44) and depression (ρ=0.316, 95% CI 0.20‐0.43) and a smaller correlation with stress (ρ=0.277, 95% CI 0.16‐0.39). In the adjusted regression models, each 1-point increase in generative AI dependence was associated with a 5% higher expected anxiety score (RR 1.05, 95% CI 1.01‐1.09; =.01) and a 4% higher depression score (RR 1.04, 95% CI 1.01‐1.08; =.03), whereas the association with stress was positive but nonsignificant (RR 1.03, 95% CI 1.00‐1.07; =.08). Fifth-year students had significantly greater anxiety levels than their sixth-year peers (RR 1.82, 95% CI 1.09‐3.01; =.02). No significant effects were observed for sex, age, or income. Conclusions: This study empirically examined generative AI dependence as a distinct behavioral construct and its association with mental health symptoms in medical students. Unlike prior research, this study evaluated psychological dependence on generative AI and modeled its relationship with anxiety and depression using appropriate count-based regression techniques. By providing early evidence from a Latin American context, it contributes to the emerging field of digital mental health and medical education research. These findings underscore the need for universities to promote balanced and responsible AI use, integrate digital literacy with mental health support strategies, and develop preventive policies that mitigate potential maladaptive reliance on generative AI tools.

Psilocybin-Induced Brain Changes May Explain Therapeutic Effects
Researchers at University of California, San Francisco and Imperial College London have shown that a single dose of psilocybin, the psychedelic compound found in magic mushrooms, causes likely anatomical brain changes that last for up to a month after the experience.
The study, involving healthy volunteers who had never taken a psychedelic, links temporary shifts in brain “entropy”—which is the diversity of neural activity occurring in the brain—to insight. This suggests the psychedelic trip itself is important to the drug’s longer term therapeutic effects.
The researchers found that a high dose of psilocybin led to increased entropy in the minutes and hours after taking the drug. The degree of entropy predicted how much insight, or emotional self-awareness, the participants felt the next day; and this, in turn, forecasted improvements in their sense of wellbeing a month later.
The findings may help to explain psilocybin’s therapeutic effects on conditions such as depression, anxiety, and addiction. “Psychedelic means ‘psyche-revealing,’ or making the psyche visible,” said senior author Robin Carhart-Harris, PhD, the Ralph Metzner distinguished professor of neurology at UCSF. “Our data shows that such experiences of psychological insight relate to an entropic quality of brain activity and how both are involved in causing subsequent improvements in mental health. It suggests that the trip—and its correlates in the brain—is a key component of how psychedelic therapy works.” Carhart-Harris is senior and corresponding author of the team’s published paper in Nature Communications, titled “Human brain changes after first psilocybin use.”
“Psychedelics have robust effects on acute brain function and long-term behavior but whether they also cause enduring functional and anatomical brain changes is largely unknown,” the authors wrote. Psilocybin is the precursor of the compound psilocin, a serotonin receptor agonist. “Converging evidence supports a role for serotonin 2A receptor (5-HT2AR) agonism in eliciting the characteristic brain and subjective effects of this and related psychedelics in humans,” the team continued.
For their newly reported study, Carhart-Harris and colleagues carried out an exploratory, placebo-controlled, within-patient study in 28 psychedelic-naïve participants who each received a single, high-dose (25 mg) of psilocybin. The researchers used an assortment of brain imaging and brain measurement techniques, some of which were carried out during the peak of the psychedelic experience, as well as before and one-month after drug administration. “This was an exploratory, hypothesis-generating mechanistic study in healthy volunteers,” the authors noted. None of the 28 people in the study had a diagnosed mental health condition, which gave the scientists greater freedom to do more testing.
In the first part of the experiment the subjects were given a 1 mg dose of psilocybin, which the researchers regarded as a placebo, and were then monitored with EEG, which records brain activity from electrodes on the scalp. Over the next few weeks, the researchers measured their subjects’ psychological insight, wellbeing, and cognitive ability. They examined brain activity with functional MRI (fMRI) and brain connectivity with diffusion tensor imaging (DTI).
One month after the placebo, the subjects were given 25 mg of psilocybin, a dose capable of eliciting a strong psychedelic trip. During the experience, researchers again measured the subjects’ brain activity with EEG, and in the following weeks they repeated the same tests they had given after the 1 mg dose.
This enabled the scientists to compare the effects of the psychedelic trip on the brain and mind to the effects of the placebo. “The multimodal neuroimaging design allowed us to observe changes in brain function and (potential) anatomy from 1-h (EEG) to 1-month (DTI) after high-dose psilocybin,” they explained.
The investigators found that within 60 minutes of taking the 25 mg dose of psilocybin, EEG revealed higher entropy, suggesting that the brain was processing a richer body of information under the psychedelic. A month later, the researchers looked at their subjects’ brains using DTI, which measures the diffusion of water along neural tracts in the brain, and found that they were denser and had more integrity. This is the opposite of what happens in aging, which makes these tracts more diffuse.
The researchers cautioned that more work needs to be done to better understand the meaning of this finding, but the result is a never-before-seen sign of how psychedelics can change the brain. ”The inclusion of DTI enabled us to test for long-term changes in the integrity of white matter tracts post psilocybin,” the authors stated. “Results revealed decreased axial diffusivity in prefrontal-subcortical tracts 1-month post 25mg psilocybin.”
The day after the 25 mg dose, all but one of the 28 subjects rated the trip as the “single most” unusual state of consciousness they had ever experienced. The remaining person rated it as among their top five. The study participants said they had experienced more psychological insight after taking the 25 mg of psilocybin than they had after the 1 mg placebo. The subjects also reported increased wellbeing two and four weeks after the study. This was measured from responses to statements such as, “I’ve been feeling optimistic about the future,” and “I’ve been dealing with problems well.”
As the scientists noted in their paper, “A predictive relationship was also found between brain entropy and longer-term mental-health changes—namely, improved wellbeing. Improved wellbeing could be predicted directly from acute increases in brain entropy as early as 1-h post dosing.”
A month after the study the study individuals also scored better on a test of cognitive flexibility. “Psilocybin seems to loosen up stereotyped patterns of brain activity and give people the ability to revise entrenched patterns of thought,” said first author Taylor Lyons, PhD, a research associate at Imperial College London. “The fact that these changes track with insight and improved well‑being is especially exciting.”
The scientists found that the subjects who had experienced the largest increases in brain entropy in the minutes to hours after taking psilocybin were the most likely to have increased insight the next day and increased wellbeing a month later. The researchers concluded that improved wellbeing was driven by the experience of insight.
The authors suggest that the study findings could improve treatment for people with mental illness using psilocybin, for example, by ensuring that the right dosage is used to produce the right amount of brain entropy to promote insight. “We already knew psilocybin could be helpful for treating mental illness,” Carhart-Harris said. “But now we have a much better understanding of how.”
In their paper the team concluded, “The present multi-modal neuroimaging study in healthy participants sheds light on the brain effects of first-time high-dose psychedelic use and the therapeutic action of psilocybin-therapy, suggesting that therapeutically relevant changes—i.e., improved wellbeing—can be forecast via an acute human brain action, i.e., an entropic brain effect, that is well-known to relate to the psychedelic experience … Results support a role for psychological insight in mediating the causal association between the entropic brain effect and potentially enduring improvements in wellbeing.”

STAT+: OxyContin maker Purdue Pharma set to dissolve after judge approves its criminal sentence
NEWARK, N.J. — OxyContin maker Purdue Pharma is set to be dissolved and replaced by a company focused on the public good by the week’s end, as a massive legal settlement resolving thousands of lawsuits takes effect.
A federal judge on Tuesday delivered a criminal sentence to the company to resolve a Department of Justice probe — a last necessary step to clear the way for the settlement.
U.S. District Judge Madeline Cox Arleo made her decision after listening to hours of impact statements from people who lost loved ones or struggled with addiction themselves and requested she reject the negotiated sentence. While she didn’t go that far, she said she sympathized with people who bore the brunt of an epidemic linked to more than 900,000 deaths in the U.S. since 1999.
Current Landscape of Mental Health Conversational Agents From a Trauma-Informed Care Lens: Scoping Review
Background: Conversational agents (CAs) are increasingly used in mental health care to enhance access and engagement. However, their safe, ethical, and user-sensitive design remains a challenge. Despite growing attention to trauma-informed approaches in human-computer interaction, there is limited work on how the trauma-informed care (TIC) framework could be applied in the design of mental health CAs and no comprehensive synthesis to date. Objective: Guided by the Substance Abuse and Mental Health Services Administration’s TIC framework, this scoping review explored how TIC principles (safety; trustworthiness and transparency; collaboration and mutuality; empowerment, voice, and choice; peer support; and cultural, historical, and gender issues) are currently represented in the design and evaluation of mental health conversational agents (MHCAs) and identified gaps and opportunities to promote more trauma-informed design practices. Methods: Online databases, as well as a secondary survey of citation lists from an initial search, were used to identify English-language journal articles and conference proceedings from 2000 to 2024 that empirically evaluated an independent, web- or app-based, unassisted CA used for mental health and included concepts from TIC. Results: Our analysis included 38 publications (n=28, 73.7%, published in 2020 or later) covering 28 distinct MHCAs. Most studies used experimental methods (n=23, 60.6%) or user studies (n=11, 28.9%), with samples skewed toward female (men: mean 34.92%, SD 18.64%), young in age (mean 32.52, SD 14.6 y), and predominantly nonclinical (n=29, 76.3%). MHCAs were largely rule-based prototypes. No studies explicitly referenced the TIC framework as a guiding lens for MHCA design or evaluation. A total of 26 studies referenced terminology from TIC core principles but rarely defined them, while all 38 included language that could be linked to one or more principles. Overall, TIC-related concepts appeared most often within intervention design descriptions, qualitative assessments, or as items embedded in questionnaires evaluating broader constructs. Trustworthiness and transparency, safety, empowerment, voice and choice, and collaboration and mutuality were comparatively well addressed, while peer support and cultural, historical, and gender issues were largely absent. Design recommendations, where present, were relatively broad and emphasized secure, customizable, reliable, human-like, and context-sensitive MHCAs that offered multimodal interaction, goal setting and tracking, and transparency. Conclusions: Studies did not self-identify as using Substance Abuse and Mental Health Services Administration’s framework for TIC, making it more difficult to identify its elements. The fragmented terms, disciplines, and metrics used make it difficult to draw more systematic conclusions about the current research landscape related to TIC, but our analysis indicates TIC to be a descriptive and potentially unifying framework and provides a starting point for the explicit trauma-informed MHCA research and design.

Dissociation: Signs and Causes in Children
When people use the word dissociation, it can sound alarming. You may have seen it on social media, heard your child mention it, or noticed your child seeming “checked out” and wondered if that’s what’s happening. Dissociation can be confusing because it exists on a spectrum — from everyday experiences like daydreaming to more serious symptoms that may signal that a child is overwhelmed or struggling. The good news is that dissociation is often a temporary coping mechanism, and when it does become a problem, there are effective ways to help.
What is dissociation?
In simple terms, dissociation is a kind of mental disconnection. “When I think of dissociation, I think of there being some sort of disconnect between an individual and their sense of self, or a period of time that you later can’t recall, or feeling like you’re disconnected from your body,” says Lauren Allerhand, PsyD, a clinical psychologist at the Child Mind Institute and co-director of its DBT program.
Some kids describe dissociation as feeling spaced out, numb, or disconnected from their body or surroundings. Others say they feel like they’re watching themselves from outside their body, or that the world around them doesn’t feel real. “There’s some period of time where your normal sense of flow is disrupted,” Dr. Allerhand explains.
Is dissociation normal?
In its mildest form, dissociation is a commonplace occurrence. Kids might daydream in class, zone out during something boring like a long car trip, or feel detached when they are overwhelmed in some way. These experiences are usually not a cause for concern. “Our brains do a really good job of protecting ourselves,” Dr. Allerhand says. “Sometimes our brains develop strategies to protect us that are healthy, and other times they develop strategies that might work in short bursts but become less helpful if they happen too much.”
When dissociation happens often, or interferes with daily life, it may signal that a child is struggling with something more serious than ordinary, intermittent stress. “If it’s happening all the time, it’s less effective as a coping mechanism” because of the toll it can take when there is memory loss, confusion, and feeling disconnected to the self, she explains.
What does dissociation feel like?
Children and teens may describe dissociation differently. Some say they feel:
- Like they’re in a dream
- Emotionally numb
- Detached from their body
- Like they’re watching themselves in a movie
- Like things around them aren’t real
“Kids might say they feel like a robot. Everything feels fake around them,” Dr. Allerhand says. “Younger children may not have the words to describe what they’re experiencing. Instead, parents might notice their child seems unusually quiet, unresponsive, or ‘not themselves.’”
Why do kids dissociate?
Dissociation is often linked to stress or overwhelming emotions — kids may dissociate when they feel unable to cope with what’s happening around them. “This could be a response to any sort of highly intense emotion or experience,” Dr. Allerhand says, such as:
- Trauma
- Anxiety or panic
- Intense emotions
- Depression
- Major life changes
- Overwhelming stress
“It’s another way of coping with stress or trauma,” says Tanvi Bahuguna, PsyD, a clinical psychologist at the Child Mind Institute who specializes in trauma and mood disorders. “There’s this psychological process that helps them disconnect from overwhelming pain.” Some kids dissociate during panic attacks or periods of intense anxiety. Children who have experienced significant adversity may be more likely to dissociate. These experiences can include:
- Abuse
- Neglect
- Family instability (housing instability, domestic violence, addiction)
- Loss of a family member, especially through violence or suicide
Still, experts are quick to note that dissociation doesn’t automatically mean a child has experienced trauma or has a serious disorder. “There are lots of exits on this highway before we’re at a dissociative disorder,” Dr. Allerhand says, adding that a full-blown dissociative disorder is very rare in children.
Mild vs. serious dissociation
It can be hard to recognize when a child is experiencing more serious dissociation because it doesn’t always look different from daydreaming or inattention. One key difference is distress. “Spacing out or not paying attention is not often experienced as distressing,” Dr. Allerhand says. Moderate or serious dissociation “is often somewhat distressing.” Kids who are daydreaming are still connected to themselves and their surroundings; kids who are experiencing more serious dissociation may feel cut off from their body, emotions, or reality altogether.
Using grounding techniques for dissociation
If you think your child may be dissociating, the most important thing you can do is not panic or try to get your child to “snap out of it.” “The number one thing a parent can do is stay as calm as possible,” Dr. Bahuguna says. Speak gently, use short sentences, and reassure your child that they’re safe. Saying your child’s name and reminding them you’re there can help them reconnect.
Grounding techniques can also bring kids back into the present moment. One common method is called the 5-4-3-2-1 technique: Ask the child to name five things they can see, four things they can feel, three things they can hear, two things they can smell, one thing they can taste or imagine tasting. Other grounding strategies include:
- Deep breathing
- Squeezing a stress ball
- Holding something cold
- Gently moving the body
If you find your child often dissociates, Dr. Allerhand recommends helping them make a plan for it. During a calm moment, talk with your child about what they find helpful. “I noticed that this is happening. How can I help you when this is happening?” she suggests asking. Having a plan in advance makes it easier to respond in the moment — and in the meantime, stay nearby and make sure your child is safe until the episode passes.
When should parents seek help for a child who dissociates?
If dissociation is frequent, distressing, or associated with changes in your child’s functioning, seeking professional support is appropriate. “If something dissociative happens, and there’s a really big change in your child’s functioning, then I would be concerned,” Dr. Allerhand says.
Signs it may be time to reach out include:
- Memory gaps after the episode
- Noticeable personality changes
- Difficulty at school
- Withdrawal from friends or activities
- Significant distress or confusion
A good place to start would be talking to your pediatrician, who may refer you to a mental health professional. “If your child is displaying behaviors that seem out of the ordinary, you should trust your instincts,” Dr. Allerhand says.
How to identify dissociation
To determine whether a child is dissociating, a mental health professional gathers information from multiple sources, including parents, the child, and sometimes teachers, asking about the child’s behaviors, history, and any recent stressors or changes in behavior.
“The first thing would be a structured diagnostic interview with a qualified clinician,” Dr. Allerhand explains. “Parents bring the history and describe the behavior, and then the clinician meets with the child.” Clinicians also consider whether dissociation might be a symptom of another condition, such as post-traumatic stress disorder, borderline personality disorder, anxiety (especially panic disorder), and depression.
“It’s really gathering history, meeting the child, observing the child, and figuring out what this cluster of behaviors leads to,” she says. It’s more frequent to find that dissociation is a result of another disorder than an actual dissociative disorder.
How is dissociation treated?
Treatment depends on what’s driving the dissociation. If trauma is involved, therapy may focus on helping the child process difficult experiences and build coping skills. Evidence-based approaches include trauma-focused cognitive behavioral therapy (TF-CBT) and eye movement desensitization and reprocessing (EMDR).
If anxiety or emotional overwhelm is the primary cause, treatment may focus on emotion regulation, grounding techniques, and identifying triggers and early warning signs. Therapy, such as dialectical behavior therapy (DBT), typically involves both children and parents, helping families recognize patterns and respond in supportive ways.
For more severe or persistent dissociation, treatment may happen in phases — beginning with safety and stabilization, then skill-building, and eventually, when appropriate, processing difficult experiences. “The goal is helping the child learn to cope with their experience and stay in their body,” Dr. Allerhand says.
What are dissociative disorders?
In children and teens, dissociation is usually a symptom of another condition. But in cases of very serious early trauma, abuse, or neglect, it can progress into a full-blown disorder. There are a number of dissociative disorders, including:
- Dissociative identity disorder (what was once called multiple personality disorder) involves two or more distinct personality states and gaps in memory and is typically linked to significant early trauma. Parents who search online may find alarming information, but Dr. Allerhand says this condition is very rare in kids.
- Dissociative amnesia involves gaps in memory that can’t be explained by ordinary forgetfulness — such as not remembering important personal information or periods of time — and is often associated with stressful or traumatic experiences.
- Depersonalization/derealization disorder involves feeling detached from oneself, as though watching yourself from outside your body, or feeling that the world around you isn’t real.
These disorders sometimes attract media attention, but they are extremely rare in children. What’s important for parents to know is that if you see dissociative behavior in a child, it’s most likely a normal coping mechanism for a child experiencing some stress or intense emotion. If it persists, is causing distress, or is interfering with a child’s life, it’s time to consult a pediatrician or mental health professional. Identifying what might be causing the behavior is the first step to getting appropriate treatment.
Frequently Asked Questions
Dissociation is a mental disconnection from your thoughts, feelings, body, or surroundings. Kids may feel spaced out, numb, or like they’re watching themselves from the outside, as if the world doesn’t feel real.
Common signs include feeling detached from the body, emotionally numb, or like you’re in a dream. Some kids seem unusually quiet or “not themselves,” while others have trouble recalling what happened during that time.
Dissociation is often a response to stress, anxiety, or overwhelming emotions. It can also be linked to trauma, major life changes (such as the sudden loss of a family member), or intense feelings the child doesn’t yet know how to manage.
Grounding techniques can help bring you back to the present moment, like naming what you see, hear, and feel, or focusing on breathing. Having a plan for what you will do the next time can make it easier to manage when it happens.
