How Does Puberty Affect Dopamine and Norepinephrine in ADHD Brains? 

Puberty is a critical period of development, marked by hormonal shifts that significantly impact the brain. For individuals with ADHD, these changes can intensify existing symptoms related to dopamine and norepinephrine dysfunction, two key neurotransmitters involved in attention, mood regulation, and executive function. The effects of puberty on these neurotransmitters can further complicate ADHD symptoms during adolescence. 

Dopamine and Reward Sensitivity in Adolescence 

During puberty, there is a surge in dopamine activity, which is linked to increased reward sensitivity and motivation. This heightened dopamine response can lead to impulsivity and risk-taking behaviours, which are common in adolescents with ADHD. For these individuals, the natural increase in dopamine activity may exacerbate existing dopamine dysfunction, making it even harder to regulate attention and behaviour. The result is often a stronger drive for immediate rewards, contributing to difficulties with long-term goal setting and focus. 

Norepinephrine and Emotional Regulation 

Norepinephrine, which plays a key role in arousal, attention, and emotional regulation, is also affected during puberty. As hormonal shifts occur, norepinephrine levels fluctuate, impacting the brain’s ability to stay alert and control emotional responses. Adolescents with ADHD, already struggling with norepinephrine dysregulation, may experience heightened emotional volatility, irritability, and difficulties in regulating their responses to stress. 

Neural Plasticity and ADHD in Adolescence 

Puberty also brings changes in neural plasticity, the brain’s ability to reorganise and adapt. For individuals with ADHD, this period of development offers both challenges and opportunities. While puberty may worsen symptoms due to neurotransmitter imbalances, it can also present a critical window for interventions that leverage neural plasticity to improve cognitive and emotional regulation.
