ADHD involves complex interactions between dopamine (DA) and serotonin (5-HT), with research suggesting lower DA signaling (impacting motivation/reward) and potential DA transporter issues (too fast reuptake), while altered 5-HT levels (affecting mood, impulse control) also contribute, often linked to genetics and comorbid conditions like anxiety/depression, showing interplay where DA and 5-HT systems influence each other.
ADHD is usually framed as a dopamine-and-norepinephrine condition, but recent studies have revealed that serotonin may also play a significant role.
The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
People with ADHD often experience hyperfocus, an intense state of deep concentration, followed by a crash associated with fatigue and low motivation. This shift happens due to dopamine imbalances, difficulty toggling between brain networks, and mental exhaustion.
The 20-minute rule for ADHD is a productivity strategy to overcome task paralysis by committing to work on a task for just 20 minutes, leveraging the brain's need for dopamine and short bursts of focus, making it easier to start and build momentum, with the option to stop or continue after the timer goes off, and it's a variation of the Pomodoro Technique, adapted for ADHD's unique challenges like time blindness. It helps by reducing overwhelm, providing a clear starting point, and creating a dopamine-boosting win, even if you only work for that short period.
Increase stress relief by exercising outdoors—people with ADHD often benefit from sunshine and green surroundings. Try relaxing forms of exercise, such as mindful walking, yoga, or tai chi. In addition to relieving stress, they can teach you to better control your attention and impulses.
What is the Five-Second Rule? The Five-Second Rule is a technique to get things done the moment they cross your mind. The rule is once you get an instinct or gut feeling to do something that you know you should be doing, start it immediately.
Dopamine levels are most depleted by chronic stress, poor sleep, lack of protein/nutrients, obesity, and excessive sugar/saturated fats, which desensitize receptors and impair production; substance misuse (like cocaine) and certain health conditions (like Parkinson's) also directly damage dopamine systems, reducing its availability. Unhealthy lifestyle habits, especially those involving processed foods and lack of sleep, significantly deplete this crucial neurotransmitter.
One of the most significant differences between an ADHD brain vs. a normal brain is the level of norepinephrine (a neurotransmitter). Norepinephrine is synthesized from dopamine. Since the two go hand-in-hand, experts believe that lower levels of dopamine and norepinephrine are both linked to ADHD.
Intense emotions and hyperfocus
Kids with ADHD often feel emotions more deeply than other kids do, and love is no exception. When teens with ADHD fall in love, the good — and bad — feelings that come with it can be even more intense and more disruptive. New relationships or crushes are exciting and (mostly) enjoyable.
The ADHD burnout cycle is a pattern where constant effort to manage ADHD symptoms (like executive dysfunction, overstimulation, and masking) leads to extreme mental/physical exhaustion, a "crash," and a shame spiral, often followed by trying to overcompensate again, repeating the cycle. It involves phases like the initial push/overcompensation, the struggle/stress, the collapse/shutdown, and the guilt-ridden recovery attempt, resulting in fatigue, irritability, procrastination, and disengagement from life.
The top 3 core symptoms of ADHD are inattention (difficulty focusing, staying organized), hyperactivity (excess restlessness, excessive movement), and impulsivity (acting without thinking, poor self-control). People with ADHD often experience a combination of these, though some might primarily struggle with inattention (inattentive type) or hyperactivity/impulsivity (hyperactive-impulsive type).
A dopamine imbalance can cause depression symptoms, such as apathy and feelings of hopelessness, while a serotonin imbalance can affect the processing of emotions.
Instead of physical hyperactivity, those with inattentive ADHD deal with issues like forgetfulness, difficulty focusing, or frequently getting lost in thought. For example, you might be the person who sits quietly through a meeting but realises at the end that you can't remember half of what was said.
24-Hour Hot Spot: Have a designated area somewhere like your desk where you can place your “need to-dos.” Place anything there that needs your attention within 24 hours so that it doesn't get lost. Pocket Notes: Writing on your hand is risky; try writing important things on notes and putting them in your pocket.
The ADHD "2-Minute Rule" suggests doing any task taking under two minutes immediately to build momentum, but it often backfires by derailing focus due to weak working memory, time blindness, and transition difficulties in people with ADHD. A better approach is to write down these quick tasks on a separate "catch-all" list instead of interrupting your main work, then schedule specific times to review and tackle them, or use a slightly longer timeframe like a 5-minute rule to prevent getting lost down "rabbit holes".
The onset of attention-deficit-hyperactivity-disorder (ADHD) in childhood is characterized by developmentally inappropriate levels of hyperactivity, impulsivity and inattention. A chronic deficit of serotonin (5-HT) at the synapse may trigger symptoms of ADHD.
Looking at the brain helps physicians know what is causing those symptoms. Research published in Radiology indicates that functional brain imaging can identify ADHD.
If you have low levels of dopamine, you may feel less motivated and excited about things in your life. Many illnesses are linked in some way to problems with how dopamine is working in our bodies. These include: Parkinson's disease.
Vitamin D has been identified as a key factor in dopaminergic neurogenesis and differentiation. Consequently, developmental vitamin D (DVD) deficiency has been linked to disorders of abnormal dopamine signalling with a neurodevelopmental basis such as schizophrenia.
Building Your Dopamine Menu
The 24-hour rule for ADHD is a self-regulation strategy to combat impulsivity by creating a mandatory waiting period (often a full day) before reacting to emotionally charged situations or making significant decisions, allowing time for reflection and reducing regretful snap judgments, especially for things like impulse purchases or arguments. It's a pause button that gives the brain space to process, move from impulse to intention, and evaluate choices more logically, helping manage ADHD's impact on emotional regulation and decision-making.
There is significant research that shows mindfulness and meditation improve mood and positive feelings. Moreover, meditation has been demonstrated to improve many symptoms of ADHD including focus, concentration and mood regulation. There are many strategies for increasing mindfulness.
Mel lived her entire life with symptoms of ADHD and crushing anxiety because of it. But she was never diagnosed until the age of 47.
