Understanding ADHD in Kids: Diagnosis, Myths and Modern Treatments

Did you know that countless children struggle daily with focus, impulsivity, and restlessness—often without knowing why? ADHD is a hidden challenge that can affect learning, behavior, and relationships, yet many cases go unnoticed.

Let’s explore what ADHD looks like, how it impacts kids and teens, and the support options that can truly make a difference.

What is ADHD

Attention-deficit/hyperactivity disorder (ADHD) is a complex neurodevelopmental disorder affecting children’s ability to focus, pay attention to things (being inattentive), have high energy levels, and self-control, where kids may be impatient and show strong emotional reactions to small things.

Kids with ADHD have differences in how their brains develop and work, causing problems with their attention, affecting teens and children at school, at home, and in friendships.

While it is most often diagnosed in kids, ADHD can last into adulthood. The signs of this condition typically begin early in childhood; however, some individuals may not discover they have it until later in life.

Types of ADHD

ADHD is divided into three types.

• ADHD, combined: It is the most common type; a kid with this type is hyperactive and impulsive.
• ADHD, impulsive/hyperactive: It is the least common type of ADHD; a kid with this type is impulsive and hyperactive, but they don’t have trouble paying attention.
• ADHD, inattentive and distractable: A kid with this type is mostly easily distracted and inattentive.

Signs & Symptoms of ADHD:

Signs and symptoms of ADHD vary from kid to kid, but most children tend to show a combination of symptoms, such as:

• Hyperactivity: Overactive, talks too much, constantly in motion
• Impulsivity: A child acts without thinking, such as interrupting others.
• Inattention: Children have trouble paying attention or are easily distracted.

Hyperactivity symptoms

• Talks a lot
• Hard time doing quiet activities
• Loses or forgets things often and repeatedly
• Seems to always be in motion (climbs or runs, even if not required)
• Trouble with finishing tasks (not able to stay on task and shifting from one task to another without completing any single task)
• Fidgets with hands
• Squirming (twisting or wriggling the body from side to side, due to the result of nervousness or discomfort)

Impulsivity symptoms

• Often interrupts others
• Takes risks often without thinking before
• Has a hard time waiting for their turn in school or social games

Inattention symptoms

• Forgetful
• Easily distracted
• Hard time attending to details
• Poor study skills for age
• Short attention span for age
• Hard time listening to others
• Poor organizational skills
• Losing things often

Remember, many of these symptoms may happen in teens and children who don’t have ADHD, too. A crucial aspect of diagnosis is that the symptoms must significantly impact how the child functions both at home and in school.

Causes of ADHD

The causes of ADHD are still unclear, but it’s known to be a complex interplay of genetic (runs in families) and environmental factors. One out of 4 kids with ADHD also has a parent with ADHD.

Genetics: There is no single gene that is solely responsible, but several genes have been linked to ADHD. Having a close family member with this condition can raise the risk of developing it.

Brain structure and function: Some studies suggest that certain areas of the brain, such as the cerebellar vermis, caudate nucleus, and frontal lobes, may be smaller or exhibit different activity patterns in children with ADHD.

Environmental factors: The following factors are associated with developing ADHD:

• Premature birth (before 37 weeks of pregnancy)
• Having epilepsy
• Sustaining a brain injury or being autistic
• Exposed to harmful toxins (like lead)
• Exposed to drugs during pregnancy
• Alcohol or tobacco use during pregnancy

Some studies have shown that children with ADHD may have differences in:

• Areas of the brain that control attention, social skills, and movement
• Chemicals that control communication in the brain

Experts also believe that these children tend to mature later than kids without the condition.

Researchers have found no evidence that ADHD could be caused by:

• Vaccines
• Sugar
• TV or video games
• Poor parenting
• Bad diet
• Loud noises, bright lights, or stress

Complications of ADHD

If left untreated, ADHD can cause:

• Low self-esteem
• Increased risk of developing substance use disorders when they’re older
• Poor grades
• Inability to reach their full potential
• Difficulty in social situations
• Trouble getting and keeping a job when they’re older

Common myths vs facts

Myth: ADHD is not a real condition.

Fact: ADHD is a recognized complex neurodevelopmental disorder with research showing differences in brain structure and function.

Myth: ADHD is caused by poor parenting.

Fact: No, this is a misconception. The causes of ADHD are still unclear. Genetic and environmental risk factors are believed to be causes rather than results of parenting style.

Myth: ADHD is just an excuse for laziness.

Fact: No, it is not true. ADHD is a real condition with neurological and biological underpinnings, not a lack of motivation.

Myth: All children with ADHD are hyperactive.

Fact: Not all children with ADHD are hyperactive; some may primarily struggle with inattention.

Myth: ADHD can be managed only with medication.

Fact: No, it is false. Although medication can be given, it’s not the only approach. Behavioral therapy, environmental modifications, and lifestyle changes can also play a significant role in managing ADHD.

Myth: ADHD is a learning disability.

Fact: While it is not a learning disability, it can affect a child’s ability to learn and succeed in school due to difficulties with organization, focus, and time management.

Myth: ADHD only affects boys.

Fact: While boys have a high chance of being diagnosed with ADHD, this may be due to differences in how symptoms present, with girls more likely to be diagnosed with the inattentive type.

Myth: ADHD is only a problem in childhood, and it will go away later.

Fact: No, ADHD often continues into adulthood and doesn’t just go away with age. However, some symptoms of ADHD may lessen or change with age.

How ADHD is diagnosed?

There are no blood tests or lab tests for ADHD. A paediatrician, child psychiatrist, or mental health expert will make a diagnosis of ADHD based on an ADHD assessment, including a physical exam, medical history, and symptoms. This involves talking to the child, their parents, and others—such as family members, friends, and teachers—to learn more about the child’s behaviour. It also includes observing the child, checking their vision and hearing to rule out other causes, and assessing their skills and thinking abilities.

The doctor first asks about the child’s behaviour, health, and activity, then checks if the child meets the criteria for an ADHD diagnosis:

• The symptoms last for 6 months or longer.
• They have at least 6 ADHD symptoms, such as fidgeting a lot or being easily disrupted.
• Symptoms started before age 12
• Symptoms interfere with the child’s daily activities, including home, school, and social life.
• Another medical condition is not responsible for these symptoms.

Diagnosis occurs in three steps. Doctors:

• Detect clusters of behaviours related to activity and attention
• Rule out alternative causes of these behaviours (like anxiety or depression).
• Confirm the presence of any co-occurring conditions

Kids with ADHD often have other mental health conditions like

• Depression
• Anxiety
• Oppositional defiant disorder

They may have other neurodevelopmental disorders, like learning disabilities or autism. The child’s doctor may recommend additional assessments to diagnose or rule out these other conditions.

Childhood ADHD Treatment

Treatment of ADHD depends on the patient’s age, symptoms, severity of the condition, and general health. ADHD treatments mainly fall into two groups: behavioural and medical treatments.

Medical treatments for ADHD

• Psychostimulant medicines: Psychostimulants (or stimulants) such as methylphenidates or amphetamines are an effective treatment for ADHD, helping the patients to ignore distractions, slow down, and focus their thoughts. ADHD drugs may show side effects such as appetite loss, sleep problems, or headaches; however, side effects are mild and don’t last long.
• Non-stimulant medicines: Some non-stimulant drugs approved for ADHD treatment in 2003 do not work as quickly as stimulants, and their effect can last up to 24 hours. These drugs decrease the symptoms and are often used in conjunction with stimulant medicines for better results.

Medications don’t work the same for all children; a child may respond well to one medication but not to another.

Behavioural therapy for ADHD

Kids with ADHD often show behaviours that can be very disruptive to others. Behaviour therapy is a treatment approach that can help reduce disruptive behaviours and increase self-regulation skills. A therapist or doctor can teach children techniques to better manage their behaviour, respond effectively to emotional challenges, and strengthen the social, emotional, and planning skills that are often affected by ADHD.

Reminder:

For children under the age of 6, experts recommend trying behavior therapy before considering medication, as medication may be less effective and its side effects can be more serious.

Parenting strategies for ADHD

One type is parent training in behaviour management. Behaviour therapy works effectively in young children when it is delivered by parents.

• Encouraging routines
• Creating more structure and clear expectations
• Discouraging negative behaviours
• Rewarding good behaviours
• Managing distractions (turning off the TV and social media, limiting noise, and providing a clean workspace)
• Limiting choices: To help the child not feel overwhelmed or overstimulated, offer choices with only a few options.
• Be clear and specific when you talk with a child.
• Break down the complicated tasks into simpler, shorter steps.
• Using goals and praising or other rewards
• Creating positive opportunities
• Providing a healthy lifestyle: Encouraging your child to get enough sleep, eat healthy food, be active every day, and practice deep breathing.
• Praising effort and completion

School and support systems

Teachers can help children with ADHD succeed and enjoy school more, and parents play an important role, too.

To help your child do better in class:

• Talk with your child’s teachers about any concerns.
• Work with teachers to break schoolwork into smaller, manageable parts
• Meet with teachers regularly to stay updated on your child’s progress

Healthcare providers, parents, and the school can work together to effectively manage ADHD.

School-age children also get therapy to help them with things like

• Organization
• Time management
• Planning ahead

Social skills training is another form of ADHD treatment that can benefit your child by teaching behaviours that help them build and maintain healthy social relationships.

Conclusion:

ADHD is a complex, lifelong neurodevelopmental condition that affects attention, behaviour, and self-regulation, often beginning in childhood but continuing into adulthood. While there is no cure, effective treatment such as medication, behavioural therapy, parenting strategies, and school support can help manage symptoms and improve a child’s quality of life
