ADHD is the most common developmental disorder, affecting approximately 8-12% of children worldwide.
ADHD symptoms range from very mild to very severe. The symptoms of ADHD consist of traits that everyone has (like activity level) but with ADHD these traits are magnified.
There are many children (and adults) who have some of these symptoms but not to the level that would be diagnosable. Researchers call this subthreshold ADHD. I call it ADHD–ish.
ADHD is highly genetic, with 70-80% of kids with ADHD having one or more parent with similar traits. Symptoms of ADHD can be caused by non-genetic contributors as well, such as low birth weight, delivery complications, and head injury.
ADHD diagnosis does not require formal psychological testing. What is required is a thorough collection of observations from multiple environments by a qualified clinician. Formal testing can be helpful to identify additional learning issues, anxiety, IQ level, and other developmental disorders.
Symptoms of ADHD occur in 4 main areas:
- Activity Level: restlessness, extra body energy, the need for stimulation.
- Inattention: difficulty staying focused (and not getting distracted) —especially when doing non-preferred activities.
- Impulsivity: difficulty stopping oneself or slowing down to think before acting.
- Emotion Regulation: controlling the size and frequency of emotional reactions.
ADHD has 3 presentations: Primarily Inattentive (20-30% of diagnosed kids), Primarily Hyperactive/Impulsive (less than 15%), and Combined, which is the most common presentation (50- 75%).
Degree of symptoms varies greatly depending on the situation. Situations that are fun or interesting decrease symptoms, while demanding or ‘boring’ situations often increase symptoms.
Studies show that about half of kids diagnosed with ADHD will eventually have a significant decrease in symptoms. This usually occurs during puberty and is seen most often with symptoms of hyperactivity & impulsivity (vs. inattention).
Kids with ADHD often have executive function deficits, like difficulty with memory, planning, organization, self-regulation, and goal achievement.
It is common for kids with ADHD to have other challenges as well. 44% of kids diagnosed with ADHD have deficits in other areas, such as difficulty with sensory/motor coordination, learning challenges, processing delays, anxiety, tic disorders, self-perception deficits, and social challenges.
Studies show that kids with ADHD require more repetition in learning, even when incentives or consequences are used. Learning that is highly structured and consistent produces better performance for kids with ADHD.
ADHD symptoms often present in early childhood and continue to pose a challenge throughout the school years. Approximately 75% of kids who display ADHD symptoms in preschool continue to struggle with these symptoms later in elementary and middle school.
ADHD affects the dopamine reward pathways in the brain. This creates challenges with motivation and persistence, especially if the activity is difficult or not immediately rewarding.
Due to dopamine deficits, kids with ADHD require more external rewards/motivators to complete difficult or non-preferred tasks. Both social (praise) and tangible (tokens/privileges) rewards are helpful. Rewards usually need to be delivered immediately, as delaying gratification is often a challenge for these kids.
Children with ADHD show decreased blood flow (observed through SPECT scans) to the brain regions controlling emotion, behavioral inhibition, and attention.
EEG measurements of brainwave activity show that children with ADHD have an average of 32% excess theta band activity. Theta band represents a drowsy/inattentive cortical (brain) state. These children also show decreased beta wave activity. Beta waves represent an active/attentive cortical state.
Contrary to popular myth, ADHD is not over-diagnosed. Studies show that 50% of children in the US with ADHD get no treatment.
Children with ADHD are at risk for higher rates of self-esteem problems, which are often evident by age 7.
The American Academy of Pediatrics (AAP) recommends a multi- faceted treatment approach for ADHD, with academic, family, and social supports provided as necessary.
AAP and CDC (Centers for Disease Control and Prevention) advise behavioral therapy for children with ADHD under 6 years. For children over 6 years (and also children under 6 who do not get enough progress from therapy), they recommend a combination of therapy and medication.
Medications for ADHD often provide substantial help by increasing focus and self-regulation and decreasing impulsive behaviors. Most of them work by increasing both Dopamine and Beta wave activity in the brain.
To date, no natural remedies or elimination diets have proven as effective as standard medications for treating ADHD symptoms. Adding Omega 3 fish oils has shown to have a some positive effect on symptoms (both inattention and hyperactivity), though results are inconsistent. The following meta- analysis of several studies connects specifically omega 3 EPA intake with improved symptoms
Additional therapies that show efficacy for ADHD:
- Positive parenting training
- Parent education
- Classroom behavioral support
- Social skills training (groups)
- Occupational therapy (OT)
- Speech therapy
- Programs that promote self-regulation (mindfulness, martial arts, yoga)
