If you are a parent or caregiver noticing changes in your teen, such as withdrawing from friends, struggling to get out of bed, becoming unusually anxious, having trouble concentrating, or falling behind in school, it is completely understandable to feel worried. It can be difficult to tell what is a normal part of growing up and what may be a sign that your child needs support. Searching online often adds more stress because the information can be confusing or overwhelming.
At HillsidesCares in Pasadena, we work with youth ages 6 to 17 every day, and we understand how uncertain this time can feel for families. You do not have to figure everything out on your own. This guide explains the most common mental health disorders affecting teens today, the signs parents tend to notice first, and how to seek help if you are concerned.
How common teen mental health disorders are today
Teen mental health concerns are far more common than many families realize. Nearly 49.5 percent of adolescents have experienced a mental health disorder at some point in their lives.
One in seven adolescents globally is living with a mental health condition, and emotional disorders such as anxiety and depression are among the leading causes of illness and disability in this age group.
These numbers reflect what many parents see at home. Teens today face significant pressure related to school, social expectations, identity development, and digital life.
Although the statistics may be concerning, they also show something important. You and your teen are not alone, and early support can make a meaningful difference.
Why teens experience mental health challenges
Adolescence is a time of rapid physical, emotional, and neurological development. This growth is essential, but it can also increase vulnerability to stress. Some common pressures include:
- Academic expectations
- Social comparison and online visibility
- Family changes or conflict
- Peer pressure and identity exploration
- Experiences of bullying or exclusion
Exposure to adversity, discrimination, or violence can increase risk, and some teens face challenges related to developmental conditions such as ADHD or autism spectrum disorder.
Supportive relationships at home and school, along with healthy routines, can act as protective factors.
The most common teen mental health disorders
Every teen experiences symptoms differently, but certain conditions appear more frequently across adolescent populations. Below are some of the most common disorders affecting youth today.
Anxiety disorders in teens
Anxiety is the most common emotional disorder among adolescents. About 32 percent of teens ages 13 to 18 experience an anxiety disorder during adolescence.
Teens may experience symptoms such as:
- Persistent worry or fear
- Panic or racing thoughts
- Physical discomfort, including headaches or rapid heartbeat
- Avoidance of school, friends, or activities they once enjoyed
Anxiety can affect school performance, friendships, and everyday functioning, and early support is often very helpful.
Depression and mood disorders
Roughly 13 percent of teens experience a depressive disorder.
Symptoms in teens often differ from adults and may include irritability, withdrawal, or sudden changes in daily habits.
Parents may notice:
- Loss of interest in hobbies or friendships
- Feelings of sadness or emptiness
- Difficulty concentrating
- Changes in sleep or appetite
- Persistent fatigue
Depression is treatable, and supportive care can help teens regain stability and connection.
ADHD and disruptive behavior disorders
ADHD affects approximately nine percent of teens.
Disruptive behavior disorders may appear as difficulty managing emotions, persistent conflict, or impulsive actions.
Some teens experience these symptoms alongside anxiety, depression, or trauma, which may require an integrated treatment approach.
Eating disorders
Eating disorders affect an estimated three percent of adolescents and often emerge during middle or high school years.
Warning signs may include:
- Sudden weight changes
- Strict dieting or intense focus on exercise
- Withdrawing from shared meals
- Dizziness, fatigue, or feeling cold often
Eating disorders can affect physical and emotional health, and early intervention is important.
Substance use and co-occurring symptoms
HillsidesCares treats substance use only when it co-occurs with mental health symptoms. Some teens turn to substances when they are trying to cope with emotional pain, anxiety, depression, or trauma. Alcohol, cannabis, and other risky behaviors can be common coping patterns during adolescence.
Self-harm and thoughts of suicide
Self-harm and suicidal thoughts are signs that a teen is experiencing distress that needs immediate attention. The WHO reports that suicide is one of the leading causes of death for people ages 15 to 29.
If your teen expresses hopelessness or begins behaving in ways that concern you, it is important to reach out for help as soon as possible.
Warning signs parents often notice
Common signs that a teen may need additional support include:
- Losing interest in activities they once enjoyed
- Having persistent low energy or fatigue
- Eating or sleeping difficulties
- Spending more time alone
- Extreme dieting or binge eating
- Using substances to cope
- Risk-taking or destructive behaviors
- Self-harm
- Hearing or seeing things others do not
If these changes continue or make daily life harder, a professional evaluation can help clarify what your teen is experiencing.
When teen behavior becomes a red flag
Every teen experiences emotional ups and downs, but when symptoms last for several weeks, cause significant stress, or interfere with school, friendships, or home life, it may be time to seek support.
Many families start by exploring teen mental health treatment in Pasadena to better understand what their child needs and what level of care may be right.

Teen mental health disorder FAQs
Below are answers to questions many parents and caregivers ask when they are first exploring mental health support for their teen.
Can my teen grow out of these symptoms on their own?
Some emotional ups and downs are part of adolescence, but persistent anxiety, sadness, withdrawal, or big behavior changes often signal something more than a temporary phase. When symptoms interfere with daily life, school, or relationships, getting support can make a significant difference in how your teen feels and functions.
How do I talk to my teen about getting help?
Teens often respond best to calm, open conversations. Let your teen know you have noticed changes and want to understand how they are feeling. Keep the focus on support rather than blame.
What if my teen refuses to talk to a therapist?
Many teens feel unsure about starting therapy, especially if they are overwhelmed or struggling to trust adults. At HillsidesCares, our teams are skilled in working gently with youth who feel hesitant. The first sessions focus on building comfort and connection so your teen does not feel pressured.
How do I know what level of care my teen needs?
A professional assessment can help determine whether outpatient counseling, IOP, PHP, or teen residential treatment in California is the right fit. The recommendation depends on safety, symptom severity, and how much support your teen needs throughout the day. Families can call us for teen mental health treatment in Pasadena to begin this conversation.
Will my teen’s school know they are in treatment?
HillsidesCares partners with parents on how much information to share with schools. Some families choose to request academic accommodations, while others prefer to keep details private. Your treatment team can help guide these decisions.
Do all teens need medication?
Medication is not appropriate for every teen. Many youths begin improving through therapy, structured support, and family involvement. When psychiatric evaluation is helpful, our team discusses options with parents so they feel fully informed.
How involved will I be during treatment?
Family involvement is a core part of our programs. Parents participate in individual and multi-family therapy, receive regular updates from the treatment team, and have opportunities to build skills that support healing at home. Parents can also visit their teens in treatment. Families can learn more through our teen mental health treatment FAQs.
How long does treatment usually take?
Length of stay depends on your teen’s symptoms, progress, and level of care. Residential, partial hospitalization, and intensive outpatient programs vary in duration, and your team will partner with you from the start to set expectations and review progress regularly.
What should I do if my teen has a crisis between appointments?
If your teen is in immediate danger or having thoughts of self-harm, call 988 or emergency services. For non-emergencies, families often benefit from safety planning with their care team so they know what steps to take until the next session.
How can I support my teen’s siblings?
Siblings are often affected by what is happening at home. Many parents find it helpful to have open, age-appropriate conversations and offer reassurance. Our family programming can also support the whole household.
Does HillsidesCares accept insurance?
Yes, HillsidesCares works with many insurance plans. Families can start by verifying your insurance coverage to learn what options are available and what services may be included.
