When is the brain fully developed
Talk through decisions step by step with your child.Many teenagers find that doing or watching sport or music, writing and other art forms are good outlets. Your child might be expressing and trying to control new emotions. Help your child find new creative and expressive outlets for feelings.New and different experiences help your child develop an independent identity, explore grown-up behaviour, and move towards independence. Let your child take some healthy risks.Here are some tips for encouraging good behaviour and strengthening positive brain connections: choose high-risk activities or risky behaviour.While your child’s brain is developing, your child might: helping your child get plenty of sleep.īehaviour strategies for teenage brain development.How you guide and influence your child will be important in helping your child to build a healthy brain too. You're an important part of your child’s environment. How are these shaping the sort of brain your child will take into adulthood? So it’s worth thinking about the range of activities and experiences your child is into – music, sports, study, languages, video games. How teenagers spend their time is crucial to brain development. For example, your child’s preferred activities and skills might become ‘hard-wired’ in the brain. The combination of your child’s unique brain and environment influences the way your child acts, thinks and feels. Have you noticed that sometimes your child’s thinking and behaviour seems quite mature, but at other times your child seems to behave or think in illogical, impulsive or emotional ways? The back-to-front development of the brain explains these shifts and changes – teenagers are working with brains that are still under construction. The amygdala is associated with emotions, impulses, aggression and instinctive behaviour. Changes in this part of the brain continue into early adulthood.īecause the prefrontal cortex is still developing, teenagers might rely on a part of the brain called the amygdala to make decisions and solve problems more than adults do. The prefrontal cortex is the decision-making part of the brain, responsible for your child’s ability to plan and think about the consequences of actions, solve problems and control impulses. The front part of the brain, the prefrontal cortex, is remodelled last. This pruning process begins in the back of the brain. This is the brain’s way of becoming more efficient, based on the ‘use it or lose it’ principle. At the same time, other connections are strengthened. The main change is that unused connections in the thinking and processing part of your child’s brain (called the grey matter) are ‘pruned’ away. Inside the teenage brainĪdolescence is a time of significant growth and development inside the teenage brain. Brain change depends on age, experience and hormonal changes in puberty. This brain remodelling happens intensively during adolescence, continuing until your child is in their mid-20s. The early years are a critical time for brain development, but the brain still needs a lot of remodelling before it can function as an adult brain.
By the time they’re six, their brains are already about 90-95% of adult size. Children’s brains have a massive growth spurt when they’re very young.
