The three core symptoms traditionally associated with Attention-Deficit/Hyperactivity Disorder (ADHD) are inattention, hyperactivity, and impulsivity, often presenting in different combinations (inattentive type, hyperactive-impulsive type, or combined type) that significantly impact daily functioning, studies, and relationships.
People with ADHD may experience an ongoing pattern of:
The mnemonic of “The Three C's” (Catching, Checking, and Changing) can be particularly helpful to children in learning this process. To engage children in treatment, therapists often frame the therapy experience as “becoming a detective” to investigate their thinking.
1. Adults can have ADHD.
There are 3 types:
Symptoms of ADHD usually start before the age of 12. They involve a person's ability to pay attention to things (being inattentive), having high energy levels (being hyperactive) and their ability to control their impulses (being impulsive).
Based on the types of symptoms, three kinds (presentations) of ADHD can occur:
Adult ADHD symptoms may include:
From this perspective, three defining features of ADHD emerge that explain every aspect of the condition:
Minimize Meltdowns!
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 common signs of ADHD include:
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 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.
Dislikes or avoids activities that require paying attention for more than one or two minutes. Loses interest and starts doing something else after engaging in an activity for a few moments. Talks a lot more and makes more noise than other children of the same age. Climbs on things when instructed not to do so.
It is important to note that ADHD can mimic symptoms of ASD, leading to patients (and sometimes their clinicians) mistakenly diagnosing a person with ADHD as having ASD instead. This is because inattention can lead to missing social cues and impulsivity can lead to socially awkward or inappropriate behavior.
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).
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 Five Factor Model personality trait Openness, but not any other FFM factor, is linked to neurocognitive profiles in ADHD. ADHD subjects showed higher Neuroticism and lower Extraversion, Agreeableness, and Conscientiousness than healthy controls.
The 1-3-5 Rule for ADHD is a task management strategy where you choose 1 big task, 3 medium tasks, and 5 small tasks to accomplish daily, preventing overwhelm by structuring your to-do list into manageable categories, focusing on impact, and providing quick wins for motivation. It helps with ADHD by imposing structure, reducing decision fatigue, and breaking down overwhelming projects into actionable steps, making productivity feel less daunting.
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.
Phases and Challenges that a Newly Diagnosed ADHD Patient may well encounter
The 9 key symptoms of ADHD, often grouped under inattention and hyperactivity-impulsivity, include difficulty focusing, forgetfulness, disorganization, losing things, fidgeting, restlessness, blurting things out, interrupting, and impulsive actions, which manifest as challenges in school, work, and relationships, according to the CDC, Mayo Clinic, and Cleveland Clinic.
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.
Standard treatments for ADHD in adults typically involve medication, education, skills training and psychological counseling. A combination of these is often the most effective treatment.
