People with ADHD often have imbalances or lower levels of the neurotransmitters dopamine and norepinephrine, which affect motivation, focus, and impulse control, though serotonin may also play a role. These brain chemicals help transmit signals, and disruptions in their pathways lead to difficulties with attention, hyperactivity, and executive functions, with medications often targeting these imbalances.
ADHD has been associated with lower levels of hair, plasma, serum, and urinary zinc. Although the efficacy of supplementation with zinc is not definitively clear, there is evidence to support that many children even in developed countries have sub-optimal levels of zinc intake.
In children with ADHD, it's more active than usual. This could make it very difficult to stay focused during an attention-demanding task, such as homework. Imbalances in chemicals called neurotransmitters, which pass messages between nerve cells in the brain, may also play a role in causing ADHD symptoms.
Children with higher lead levels in their blood have an increased risk of developing ADHD symptoms. Lead affects brain development, particularly regions involved in attention regulation and impulse control. Even low levels of lead exposure can have an effect on cognitive and behavioural functioning.
Dopamine and norepinephrine are two neurotransmitters that may play a role in ADHD.
Lower levels of dopamine, in particular, track closely with ADHD symptoms. The endocrine system—which encompasses all hormonal activity—interacts with specific dopamine systems in our bodies.
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.
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".
Why are my ADHD symptoms getting worse?
ADHD is usually framed as a dopamine-and-norepinephrine condition, but recent studies have revealed that serotonin may also play a significant role.
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.
Looking at the brain helps physicians know what is causing those symptoms. Research published in Radiology indicates that functional brain imaging can identify ADHD.
There is no single cause of ADHD and the risk factors that have been identified so far appear to be non-specific. That is, risks such as chromosomal microdeletions (eg, VCFS), large, rare CNVs, extreme low birth weight and prematurity appear to affect a range of different neurodevelopmental and psychiatric phenotypes.
Although all vitamins and minerals are important for brain health, the following appear to have a significant effect on ADHD symptoms:
The 10-3 rule for ADHD is a productivity strategy involving 10 minutes of focused work followed by a 3-minute break, designed to match the ADHD brain's need for short bursts of effort, making tasks less overwhelming and procrastination easier to manage by building momentum with quick, structured intervals. It helps individuals with ADHD ease into tasks, offering a tangible goal (10 mins) and an immediate reward (3 mins) to keep focus without burnout, often incorporating movement or preferred activities during breaks.
People with ADHD often thrive when they incorporate movement, pursue passion-driven challenges, foster social relationships, and practice mindfulness. Creating a structured yet flexible routine can also improve focus and boost overall happiness.
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.
As a Psychologist With ADHD, Here Are 6 Things That Get On Our...
The "4 Fs of ADHD" refer to common, often subconscious, survival responses triggered by overwhelm or perceived threat in individuals with ADHD: Fight (anger/aggression), Flight (avoidance/withdrawal), Freeze (shutdown/blanking out), and Fawn/Fib (people-pleasing/lying to deflect issues), which stem from the brain's amygdala overreacting in modern contexts, explains ADDitude Magazine and NeuroDirect. These responses, especially Fibbing (lying), help self-preserve when facing difficulties with executive function, emotional regulation, or rejection sensitivity, notes CHADD and Brookhaven Psychotherapy.
The 5 C's of ADHD, developed by psychologist Dr. Sharon Saline, is a framework for parents and individuals to manage ADHD challenges, focusing on Self-Control, Compassion, Collaboration, Consistency, and Celebration. This approach builds skills for better emotional regulation (Self-Control), empathy (Compassion), working together (Collaboration), establishing routines (Consistency), and recognizing progress (Celebration) to foster a supportive environment and reduce stress.
For adults, 7-8 hours is recommended. Try to avoid napping during the day. Optimise your sleep environment. Make sure your environment is quiet, calm and comfortable.
Unlike traditional ADHD, which is characterized by visibly disruptive behaviors and severe impairments, high-functioning ADHD allows individuals to maintain a semblance of control in daily life. However, this comes at a cost.
The only way to know for sure is to see a doctor. That's because the disorder has several possible symptoms, and they can easily be confused with those of other conditions, such as depression or anxiety. Everyone misplaces car keys or jackets once in a while. But this kind of thing happens often when you have ADHD.
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.
