22 Facts & Statistics on Mental Health for Teens and Young Adults

1. Depression is common, and many young people still go without care

In 2024, 15.4% of U.S. adolescents aged 12–17—about 3.8 million—had a major depressive episode; 2.8 million had severe impairment, according to SAMHSA’s 2024 survey release.

Among adolescents with a major depressive episode, 60.6% received mental-health treatment in the past year. That leaves roughly four in ten without treatment. Depression can affect sleep, concentration, relationships, and safety; changes that persist or disrupt daily life deserve attention.

2. Stress and alcohol misuse can reinforce one another

Uncertainty about the future, loneliness, anxiety, and depression can lead some young people to drink to cope. Alcohol may offer short-lived relief while making sleep, judgment, and mood harder to manage.

The National Institute on Alcohol Abuse and Alcoholism’s account of pandemic-related drinking risks remains useful background to this connection. Today, ask about both emotional distress and drinking patterns, rather than addressing only one side of the problem.

3. Anxiety affects a substantial share of adolescents

The often-cited 31.9% figure describes the lifetime prevalence of an anxiety disorder among 13–18-year-olds in the 2001–2004 National Comorbidity Survey–Adolescent Supplement, as reported by NIMH. It is a historical lifetime measure, rather than a count of teenagers currently experiencing symptoms.

Persistent anxiety can interfere with school, friendships, sleep, and physical well-being. OCD can also involve severe anxiety, but it has its own pattern of intrusive obsessions and repetitive compulsions; chronic worry alone does not establish an OCD diagnosis.

4. OCD has targeted treatment options

For a young person with OCD, treatment should address the obsessions and compulsions directly. AACAP describes cognitive behavioral therapy and medication as treatment options. Exposure and response prevention, a form of CBT, helps a person face triggers while gradually resisting compulsive responses.

Families can ask whether the therapist has experience with pediatric OCD, how parents will be involved, and how progress will be assessed. Treatment is more specific than simply advising a teenager to relax or stop worrying.

5. Some young people benefit from residential treatment

Residential care can provide structure, coordinated therapy, and support throughout the day for teens whose needs cannot be met safely or effectively through outpatient care. A co-occurring mental-health condition and substance use problem may make that coordination especially valuable.

The assessment should consider safety, functioning, previous treatment, and support at home. Newport Academy, featured in this guide, provides treatment for adolescents at locations across the United States. Ask the specific location about conditions treated, age limits, medical support, family participation, and its plan for returning to school and home.

6. Prescription opioid misuse remains a youth concern

In CDC’s 2023 Youth Risk Behavior Survey, 4% of high-school students reported misusing prescription opioids in the previous 30 days. This is a more recent, shorter-window measure than the older “one in seven ever misused” figure.

Access through family or friends remains a prevention concern. Store medication securely, do not share prescriptions, and dispose of unused medicine appropriately. Some people move from prescription opioid misuse to heroin or illicit fentanyl; early help can interrupt that progression.

7. Peer pressure can shape substance use

Wanting to fit in or gain acceptance can influence teenagers’ decisions about alcohol and drugs. The Indian Health Service’s guidance for families identifies peer pressure among reasons for teen substance use.

A useful conversation goes beyond “just say no.” Ask what happens at parties, how a young person could leave an uncomfortable situation, and which adult they can contact for a ride or help. Having a practical exit plan makes refusing a substance easier.

8. Withdrawal can require medical help

Withdrawal may follow a sudden reduction or stop after repeated substance use. Symptoms vary by substance: sleep disturbance, depression, anxiety, nausea, shaking, and cravings can all occur. Alcohol withdrawal can involve seizures or delirium tremens, a severe syndrome with confusion and physical instability.

The MedlinePlus alcohol-withdrawal guidance explains when hospital care is needed. A young person who is confused, having seizures, or difficult to wake needs emergency help. When dependence is possible, arrange a clinical assessment before attempting withdrawal alone.

9. Finding care means finding the right age-specific service

Access for adolescents differs from access for adults. In SAMHSA’s 2018 National Mental Health Services Survey, 63.3% of responding mental-health facilities accepted ages 13–17, compared with 87.3% for ages 18–25 and 83.8% for ages 26–64. These historical facility percentages include participating U.S. jurisdictions.

For a current search, use FindTreatment.gov and confirm the age range with the provider. Also ask about the exact condition, insurance, waiting times, telehealth, and whether the program treats both mental-health and substance use needs.

10. Depression can disrupt education and the move into work

Depression can make concentration, attendance, completing assignments, and maintaining routines difficult. Falling behind or leaving school can narrow training and employment options, adding financial stress to an already difficult period. Some young people then turn to alcohol or drugs to cope.

Support can include treatment alongside a school plan: a named staff contact, manageable catch-up work, and help with attendance or transitions. The aim is to protect both mental health and the young person’s route back into learning, rather than treating academic difficulties as a motivation problem.

11. Bipolar disorder can begin during adolescence

Bipolar disorder often emerges in adolescence or young adulthood, although symptoms can appear earlier. Episodes involve changes in mood along with energy, activity, sleep, and functioning. The older term “manic depression” refers to this pattern of manic or hypomanic and depressive episodes.

NIMH’s guide to bipolar disorder in children and teens explains why assessment should examine episodes over time. A few mood swings alone are not enough to identify the condition; marked changes in sleep and energy are especially useful details to share with a clinician.

12. Bipolar I, bipolar II, and related conditions differ

Bipolar I

Includes a manic episode; depressive episodes may also occur.

Bipolar II

Includes hypomanic and major depressive episodes, without a full manic episode.

Cyclothymic disorder

Recurring hypomanic and depressive symptoms that do not meet full episode criteria.

Other specified or unspecified bipolar disorders

Clinically significant bipolar symptoms that do not fit the other categories.

These distinctions are described in NIMH’s bipolar-disorder overview. Bipolar II can be missed when a person first seeks help for depression, so a history of unusually high energy or reduced need for sleep matters.

13. Isolation and peer relationships are part of mental health

A teenager experiencing mental-health difficulties may withdraw from friends, struggle with conflict, or become more vulnerable to bullying. Isolation can then reduce opportunities to practice social skills and receive support.

Look for a change from that person’s usual pattern: dropping valued friendships, avoiding activities, or repeatedly staying home. Supportive contact can start small—a regular check-in, one trusted friend, or an activity that feels manageable. Family and school support should help rebuild connection without forcing a young person into overwhelming situations.

14. Bullying can affect mood, health, and school performance

StopBullying.gov describes links between bullying and depression, anxiety, health complaints, and poorer academic outcomes. Cyberbullying can extend harassment beyond the school day and make it difficult to find relief.

A response can include documenting messages, reporting threats or harassment, involving the school, and arranging mental-health support. Some young people also develop trauma-related symptoms. Take changes in sleep, school avoidance, and fear seriously, even when the bullying happens online.

15. Trauma can interfere with concentration and learning

In a 2021 school-based PTSD study in Morocco, researchers reported declining academic results in 73% of students with PTSD, concentration difficulties in approximately 35%, and memory difficulties in approximately 17%. These findings describe that study’s group.

Trauma may follow violence, witnessing violence, abuse, or other distressing events. A change in school performance can be one visible sign. Giving a student time, consistent support, and access to trauma-focused care can help address the underlying difficulty.

16. PTSD and depression often occur together

A teen or young adult with PTSD may also experience depression, anxiety, or substance use difficulties. NIMH describes a variable recovery course: some people recover within six months, while others have symptoms for a year or longer.

Treatment should address the full picture, including sleep, mood, safety, and the effects of trauma on everyday life. A person who remains distressed months after an event can still benefit from care; there is no deadline after which support is no longer worthwhile.

17. Sexual exploitation, substance use, and trauma can overlap

Substance use can increase vulnerability to exploitation, and exploitation itself can contribute to substance use and PTSD. A 2018 study of commercially sexually exploited youth cites earlier medical-care research in which 70% reported substance use.

The practical need is coordinated help: immediate safety, medical care, trauma treatment, and substance use support. Young people may fear punishment or retaliation when disclosing exploitation. A response centered on their safety makes it easier to reach services.

18. Homeless youth face overlapping trauma and treatment barriers

A 2020 shelter-clinic study summarizes earlier research reporting physical or sexual abuse in as many as 77% of homeless youth, and one or more mental-health disorders in 89% of a studied group aged 16–19.

Housing instability can also make attending appointments, storing medication, and maintaining contact with a clinician difficult. Shelter-based care, outreach, housing support, and flexible follow-up can bring treatment closer to where a young person is living.

19. Sharing injection equipment increases HIV risk

Sharing needles, syringes, or other injection equipment can transmit HIV and hepatitis. CDC’s 2024 surveillance across 19 U.S. cities examined HIV status and prevention needs among 9,237 people who inject drugs, reinforcing the importance of testing and access to prevention services.

For teens and young adults, care can combine substance use treatment with sterile equipment, HIV testing, and discussion of PrEP to prevent HIV. A clinician can advise on prevention, testing, and treatment without waiting for a substance use problem to escalate.

20. Stigma can delay a request for help

Fear of being judged, labeled, or treated differently can keep young people and families from seeking mental-health care. The 2016 research on youth mental-health stigma cited in this guide remains relevant to understanding that barrier.

Make the first step concrete and private: explain who can see information, offer a choice of trusted adults or clinicians, and avoid describing treatment as a failure. A young person does not need to wait for a crisis before asking for support.

21. Schizophrenia often first appears in young adulthood

According to NIMH, schizophrenia is typically diagnosed from the late teens to the early thirties and tends to emerge earlier in males. Social withdrawal, unusual beliefs or suspicions, and changes in perception can be early concerns.

These experiences warrant assessment, particularly when they disrupt school, work, or relationships. Severe mental illness can contribute to housing instability, and coordinated clinical, family, and practical support can help a young person maintain stability.

22. Mental-health and substance use disorders need coordinated care

In SAMHSA’s 2024 survey, approximately 792,000 adolescents aged 12–17 had both a major depressive episode and a substance use disorder in the past year—about two fifths of adolescents with a substance use disorder.

“Dual diagnosis” or “co-occurring disorders” describes this overlap. A useful treatment plan addresses both conditions, with outpatient, intensive outpatient, or residential care matched to the young person’s needs. Ask who coordinates the plan and how care continues after a program ends.
