Learn how to recognize mental health warning signs in teens and young adults, understand what's typical during adolescence, and know when it's time to seek support.
Growing up has never been simple. Today's young people are balancing school or work, friendships, family expectations, social media, and questions about their future—all while learning who they are.
It's no surprise that emotions can sometimes run high.
Many parents and caregivers wonder whether changes in a teenager's behavior are simply part of growing up or signs that something more serious may be happening. While mood swings, occasional irritability, and periods of independence are often a normal part of adolescence, persistent changes in mood, behavior, or daily functioning deserve attention.
Recognizing the difference isn't about labeling young people—it's about ensuring they receive the understanding and support they need when they need it most.
As we observe International Youth Day, it's an opportunity to remember that investing in young people's mental health is an investment in their future.
Growing Up Comes With Emotional Changes
Adolescence and young adulthood are periods of rapid physical, emotional, and social development. During these years, young people begin forming their identities, developing independence, and navigating increasingly complex relationships.
Because of these changes, it's normal for teenagers to experience:
- Occasional mood swings.
- A desire for more privacy.
- Changing interests.
- Increased sensitivity to peer relationships.
- Stress related to school, work, or future plans.
Experiencing these challenges doesn't automatically mean a young person has a mental health condition. However, when emotional or behavioral changes become intense, persistent, or interfere with daily life, it's important to pay closer attention.
Signs That May Indicate a Young Person Needs Additional Support
No single behavior can diagnose a mental health condition, but patterns over time may suggest it's time to seek professional guidance.
Some warning signs include:
- Feeling sad, hopeless, or emotionally overwhelmed for several weeks.
- Withdrawing from friends, family, or activities they once enjoyed.
- Significant changes in sleep or eating habits.
- Increased anxiety or excessive worrying.
- Frequent irritability or anger that seems out of character.
- Difficulty concentrating or a noticeable decline in school or work performance.
- Loss of motivation or interest in everyday activities.
- Increased use of alcohol or other substances as a way to cope.
- Talking about feeling worthless or like a burden.
These experiences can have many possible causes, and they don't necessarily point to a specific diagnosis. The key is noticing changes that are persistent, affect daily functioning, or cause significant distress.
Some Mental Health Conditions Can Begin Early in Life
While many emotional and behavioral changes are a normal part of growing up, it's also important to understand that some mental health conditions first emerge during childhood or adolescence. Recognizing these conditions early doesn't mean labeling a young person—it means creating opportunities for timely support, appropriate treatment, and better long-term outcomes.
Some examples include:
- Oppositional Defiant Disorder (ODD): ODD is typically diagnosed during childhood or adolescence and is characterized by a persistent pattern of angry or irritable mood, argumentative behavior, and defiance toward authority figures that goes beyond typical developmental behavior. As young people mature, symptoms may change, and some individuals may no longer meet the criteria for ODD, while others may develop different mental health or behavioral conditions that require continued support.
- Persistent Depressive Disorder (PDD), formerly called dysthymia: This is a long-lasting form of depression that can begin in childhood or adolescence. In younger people, it may appear as ongoing irritability rather than sadness and can continue into adulthood if left untreated.
- Obsessive-Compulsive Disorder (OCD): Many people experience their first symptoms during childhood or adolescence. OCD involves recurring unwanted thoughts (obsessions) and repetitive behaviors or mental rituals (compulsions) performed to reduce anxiety. With appropriate treatment, many people learn effective ways to manage these symptoms.
- Internet Gaming Disorder: Excessive gaming that begins to interfere with school, relationships, sleep, or daily responsibilities may indicate a need for professional evaluation. While enjoying video games is a normal hobby for many young people, persistent gaming that causes significant impairment should not be overlooked.
- Schizophrenia: Although schizophrenia is more commonly diagnosed in late adolescence or early adulthood, early warning signs can sometimes emerge during the teenage years. Early assessment and intervention can improve long-term outcomes and quality of life.
- Borderline Personality Disorder (BPD): Features associated with BPD often begin to emerge during adolescence, including intense emotional reactions, difficulties in relationships, an unstable sense of self, and impulsive behaviors. When these patterns are persistent and significantly affect daily functioning, a qualified mental health professional can determine whether a diagnosis is appropriate and recommend evidence-based treatment.
Having one or more of these symptoms does not necessarily mean a young person has one of these conditions. Many emotional and behavioral changes are a normal part of development. A comprehensive assessment by a qualified mental health professional is the best way to understand what a young person is experiencing and identify the most appropriate support.
How Parents and Caregivers Can Respond
When you're worried about a young person, your first instinct may be to solve the problem immediately. Often, the most helpful first step is simply to listen.
Try creating opportunities for calm, open conversations without judgment. Instead of asking, "What's wrong with you?" consider saying, "I've noticed you don't seem like yourself lately. How have you been feeling?"
Small changes in communication can make a big difference.
Other ways to provide support include:
- Validating their feelings, even if you don't fully understand them.
- Encouraging healthy routines such as regular sleep, balanced meals, and physical activity.
- Helping them maintain connections with trusted friends and supportive adults.
- Limiting criticism and focusing on collaboration.
- Seeking professional support if concerns continue or worsen.
Young people are more likely to ask for help when they feel heard rather than judged.
Why Early Support Matters
Mental health challenges often respond best when they are identified and addressed early. Reaching out for professional support doesn't mean something has gone terribly wrong—it means you're taking steps to help a young person build healthy coping skills before challenges become more difficult.
Some young people also experience more than one condition at the same time. For example, anxiety may occur alongside attention difficulties, depression may exist alongside substance use, or a young person with an intellectual or developmental disability may also experience anxiety or another mental health condition.
This is sometimes referred to as a co-occurring or dual diagnosis. Treating both conditions together allows care to be more comprehensive and tailored to the individual's needs.
Helping Young People Build Emotional Resilience
Resilience isn't about avoiding difficult emotions. It's about learning healthy ways to navigate them.
Parents, caregivers, schools, and communities all play a role in helping young people develop emotional resilience by encouraging:
- Consistent daily routines.
- Healthy sleep habits.
- Regular physical activity.
- Positive social connections.
- Time away from constant social media comparison.
- Opportunities to develop problem-solving and coping skills.
- Access to mental health support when needed.
Most importantly, remind young people that asking for help is a sign of courage—not weakness.
Key Takeaways
- Emotional ups and downs are a normal part of growing up.
- Persistent changes in mood or behavior deserve attention.
- Listening without judgment builds trust.
- Early intervention often leads to better outcomes.
- Mental health care should address the whole person, including co-occurring conditions when present.
Final Thoughts
Young people don't need adults who have all the answers—they need adults who are willing to listen, learn, and walk alongside them.
This International Youth Day, consider taking time to check in with a teenager or young adult in your life. A simple conversation can open the door to understanding, support, and hope.
Mental health challenges are not a reflection of character or potential. With compassionate support, early intervention, and access to appropriate care, young people can build the skills they need to thrive.
