The surprising science of adolescent brains

Developmental psychologist, brain scientist

Adolescence, stretching from ages 10 to 25, is a period of rapid growth and remarkable potential—not a problem to be fixed. Scientific research shows that the real drivers of mental health in young people are relationships, self-image, and family well-being, not just biology or technology. For example, social media use is linked to only a small increase in depression risk, while having strong friendships and mentally healthy parents has a much bigger impact on adolescent well-being. Rethinking the adolescent years helps society support, rather than shame, the next generation.

Teen Brains Aren’t Broken, They’re Built For Transformation

Adolescence, spanning ages 10 to 25, is a critical period of brain, body, and identity growth often misunderstood as a problem to be fixed. While society blames hormones or technology for struggles like anxiety, research shows relationships and support matter most for mental health. Excessive social media use raises depression risk by only a few percentage points, while strong friendships and family support provide far greater protection. Reframing adolescence as a time of opportunity unlocks the potential of young people and those who care for them.
