How do I know if my child has ADHD or is just energetic?

The key difference lies in persistence, intensity, and impact. Energetic children can focus on activities they enjoy, follow rules at school, and their activity level is situational. In ADHD, inattention and/or hyperactivity are persistent (more than 6 months), present in at least two settings (home and school), cause significant functional impairment, and are not explained by other factors. Only qualified professionals can make this differential diagnosis.

At what age is ADHD diagnosed?

The DSM-5 requires symptoms to be present before age 12. Diagnosis is typically made from age 6-7, when school demands reveal the difficulties. However, warning signs may be noticed as early as preschool (ages 3-5). In Brazil, the diagnosis is made by a neuropediatrician (neuropediatra) or child psychiatrist, often in collaboration with psychologists and speech therapists.

Does ADHD have a cure?

ADHD does not have a cure, as it is a neurobiological developmental condition — not a disease. However, with proper support (behavioral therapy, management strategies, and medication when needed), most children develop tools to manage their symptoms and have an excellent quality of life. About 50-60% of cases maintain symptoms into adulthood, but learn to manage them effectively.

Is ADHD medication safe for children?

Yes, when prescribed by a qualified professional with regular medical follow-up. Methylphenidate (known as Ritalin/Concerta in Brazil) and lisdexamfetamine (Vyvanse/Venvanse) are among the most studied medications in pediatric medicine, with decades of research and a well-established safety profile. The most common side effects (reduced appetite, difficulty sleeping) are usually mild and manageable with dose and timing adjustments.

Do screens and phones cause ADHD?

No. Screens do not cause ADHD — the disorder has a neurobiological and genetic basis. However, excessive screen time can mimic or worsen symptoms of inattention and impulsivity, especially in predisposed children. The rapid, constant stimulation from screens makes it harder to sustain attention for school activities. The Brazilian Society of Pediatrics (SBP) recommends limiting screen time and prioritizing active play and in-person interactions.

ADHD in Children: Symptoms, Diagnosis, and How to Help Your Child

Is your child unable to focus? Too restless? Forgets everything? Before you worry, know that restlessness and distraction are a normal part of childhood. But when these behaviors are persistent, intense, and interfere with your child's daily life, it may be time to investigate Attention Deficit Hyperactivity Disorder (ADHD). This guide will help you understand the symptoms, the diagnosis process in Brazil, treatment options, and practical strategies to help your child thrive. Remember: ADHD is not bad parenting — it is a neurobiological condition, and with the right support, children with ADHD have excellent developmental potential. If you are an expat family in Brazil, you can count on English-speaking pediatric care to navigate this journey.

What Is ADHD

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition characterized by a persistent pattern of inattention, hyperactivity, and impulsivitythat interferes with a child's functioning and development. The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) defines three presentations:

Predominantly Inattentive

Difficulty sustaining focus, seems not to listen, forgets tasks, disorganized. This is the hardest type to identifybecause the child is not “disruptive” — they are the daydreamer who is “always in their own world.”

Predominantly Hyperactive/Impulsive

Cannot sit still, talks excessively, interrupts others, acts without thinking. This is the type most often noticed early, especially in boys.

Combined

Shows significant symptoms of both inattention and hyperactivity/impulsivity. This is the most common presentation in children diagnosed with ADHD.

International data and the Brazilian Association of Attention Deficit (ABDA) indicate that ADHD affects approximately 5 to 7% of school-age children, with boys diagnosed more often (2-3:1 ratio), although the inattentive type in girls is frequently underdiagnosed.

Important

ADHD is not bad parenting, laziness, or a behavioral choice. It is a condition with a neurobiological basis, involving differences in the regulation of neurotransmitters such as dopamine and norepinephrinein the prefrontal regions of the brain. It has a strong genetic component: if one parent has ADHD, the child's chance of having it is 40-60%.

ADHD Symptoms by Type

The DSM-5 requires at least 6 symptoms (in children under 17) from one or both categories, persistent for more than 6 months, with onset before age 12 and present in at least two settings (home and school, for example). Understanding the developmental milestones helps put age-appropriate expectations in context.

Inattention Symptoms	Hyperactivity/Impulsivity Symptoms
Fails to give close attention to details, makes careless mistakes	Fidgets with hands or feet, squirms in seat constantly
Difficulty sustaining attention in tasks or play	Leaves seat when remaining seated is expected (in class, at dinner)
Does not seem to listen when spoken to directly	Runs or climbs in inappropriate situations
Does not follow through on instructions, fails to finish tasks	Unable to play or engage in activities quietly
Difficulty organizing tasks and activities	Seems “driven by a motor,” always on the go
Avoids tasks requiring sustained mental effort	Talks excessively
Loses things necessary for tasks (school supplies, toys)	Blurts out answers before questions are completed
Easily distracted by external stimuli	Has difficulty waiting their turn
Forgets daily activities (homework, errands)	Interrupts or intrudes on others' activities

How ADHD Presents at Each Age

ADHD symptoms manifest differently as children grow. Understanding these variations helps parents identify when to seek evaluation.

Ages 3 to 5 (Preschool)

•Intense restlessness — runs non-stop, climbs furniture, cannot sit still even to eat
•Cannot participate in circle time at school for more than 2 minutes
•Switches activities every moment, does not stay with any one activity
•Difficulty waiting their turn and following simple game rules
•“No brakes” behavior — acts without considering consequences (jumps from heights, runs into the street)

At this age, diagnosis is challenging because restlessness is normal. The differentiator is the intensity and persistence compared to peers of the same age.

Ages 6 to 9 (Early Elementary School)

•Academic difficultiesthat do not match the child's intelligence
•Does not copy from the board, loses materials, forgets to turn in homework
•Gets up from the chair frequently, talks excessively in class
•Difficulty with sleep routines — resistance to bedtime, difficulty “switching off”
•Quick frustration, emotional explosivity

This is the stage when most diagnoses happen, as school demands expose the difficulties.

Ages 10 to 12 (Pre-Adolescence)

•Physical hyperactivity decreases, but inner restlessness remains (“racing mind”)
•Growing difficulty with organization, planning, and time management
•Low self-esteem — feels “stupid” or “lazy” for not keeping up with classmates
•Risk of anxiety and depression as comorbidities
•Difficulty with friendships — impulsivity affects social relationships

Is It ADHD or Just Normal Behavior?

The Difference Between Normal Energy and ADHD

Normal Behavior	Possible ADHD
Restless in some situations	Restless in all settings
Can focus on activities they enjoy	Even in enjoyable activities, loses focus easily (except during hyperfocus)
Forgets things occasionally	Forgets daily, even with reminders
Restlessness improves with age	Symptoms persist and cause increasing impairment
Can follow rules at school	Chronic difficulty with rules, despite understanding them
Inattention is situational	Inattention is pervasive and affects home, school, and friendships

ADHD is defined by symptoms that are persistent (more than 6 months), present in at least 2 settings, and cause significant functional impairment. Children with signs of autism may also present overlapping symptoms — professional evaluation is essential to differentiate.

How ADHD Is Diagnosed in Brazil

There is no blood test, CT scan, or MRI that diagnoses ADHD. The diagnosis is clinical, based on a detailed history and behavioral observation across different settings. For expat families, understanding the Brazilian process is key:

Professionals Involved

Neuropediatrician (neuropediatra) — leads the diagnosis, evaluates neurological aspects
Child psychiatrist (psiquiatra infantil) — can also diagnose and treat
Neuropsychologist (neuropsicólogo) — evaluates executive functions and attention
Pediatrician (pediatra) — initial screening and referral

Assessment Tools

SNAP-IV — validated questionnaire completed by parents and teachers
Conners Scales — evaluates ADHD symptoms and comorbidities
Neuropsychological evaluation — tests of attention, memory, and executive functions
School report — essential for observing behavior in an academic context

For Expat Families

The ADHD diagnosis process in Brazil follows the same DSM-5 criteria used internationally. If your child was already evaluated abroad, bring any existing reports to the appointment. The Brazilian well-child visit schedule includes developmental screening at each appointment. School reports from international schools in São Paulo are accepted — the specialist may also request a report in Portuguese from the school.

ADHD Treatment: A Multimodal Approach

The most effective ADHD treatment is multimodal, combining different strategies. An integrative pediatric approach values looking at the whole child — not just the symptoms.

Behavioral Therapy

• Cognitive Behavioral Therapy (CBT)
• Social skills training
• Parent Management Training (PMT)
• Educational therapy for academic difficulties

Recommended as first-line treatment for preschoolers (AAP and SBP guidelines).

Management Strategies

• Visual and predictable routines
• School accommodations
• Regular physical activity (30-60 minutes/day)
• Proper sleep hygiene
• Balanced nutrition

ADHD Medication: When It Is Indicated

Medication is not the first option in every case, but it can be transformative when properly indicated. The scientific evidence is robust: the MTA study (Multimodal Treatment Study of ADHD) demonstrated that the combination of medication + behavioral therapy produced the best outcomes.

Medication	Brazilian Brand Names	Type	Duration
Methylphenidate (Ritalin)	Ritalina, Ritalina LA, Concerta	Stimulant	4h (IR) to 12h (ER)
Lisdexamfetamine (Vyvanse)	Venvanse	Stimulant	Up to 14h
Atomoxetine (Strattera)	Strattera	Non-stimulant	24h (continuous use)

Medication Access in Brazil

ADHD medications require a special prescription (receita amarela or receita B1) in Brazil, issued by the treating physician. They are available at regular pharmacies but are not covered by SUS (public healthcare). If you have private health insurance (convênio), check your plan's medication coverage. Some pharmacies offer discount programs — ask about “programa de descontos” when purchasing.

Myths vs Evidence About Medication

“It causes addiction” — False. Studies show that proper ADHD treatment in childhood actually reduces the risk of substance abuse in adolescence
“It changes their personality” — False. Medication does not change who the child is; it allows them to express their potential without the barrier of inattention
“It stunts growth” — Partially true. There may be a temporary reduction in growth velocity (1-2 cm/year), but final height is generally not compromised. The pediatrician monitors the growth curve
“It is prescribed for all hyperactive children” — False. Medication is only indicated after a formal diagnosis and when there is significant functional impairment

10 Practical Strategies for Parents

Regardless of diagnosis or medication, these strategies help any child with attention and behavioral difficulties:

1. Establish a Predictable Routine

Use visual schedules with the sequence of daily activities. Children with ADHD benefit greatly from knowing what comes next.

2. Give Clear, Short Instructions

Instead of “clean your room,” say “put the toys in the box.” One instruction at a time, with eye contact.

3. Use Positive Reinforcement

Praise the desired behavior the moment it happens: “Great job sitting down and finishing your homework!” Positive reinforcement is more effective than punishment.

4. Break Large Tasks into Smaller Parts

“Do 5 math problems, then take a 2-minute break.” Short intervals work better than demanding long periods of concentration.

5. Create a Low-Distraction Environment

During homework time, turn off the TV, put away phones, and reduce visual stimuli. An organized study corner makes a real difference.

6. Encourage Regular Physical Activity

Sports, dance, swimming, martial arts — 30 to 60 minutes of daily physical activity improves attention, mood, and sleep.

7. Use Timers and Alarms

Children with ADHD struggle with time perception. A visual timer helps make “how much time is left” tangible.

8. Stay Calm During Meltdowns

Impulsivity is not a choice. Breathe, do not react with anger. Talk later, when everyone is calm. Model the emotional regulation you want to teach.

9. Celebrate Strengths

Children with ADHD are often creative, energetic, spontaneous, and good at solving problems in unconventional ways. Celebrate these qualities!

10. Take Care of Yourself Too

Raising a child with ADHD is demanding. Seek support, join parent groups, consider therapy for yourself. Well-rested and informed parents help better.

ADHD and School: How to Help Your Child

School is where ADHD symptoms impact the child the most. Open communication between parents and school is essential:

Share the diagnosiswith the school coordinator and teachers — they need to understand that the behavior is not a “lack of willpower”
Request accommodations: front-row seating, extra time on tests, written instructions, breaks between activities
Weekly communication between school and parents — do not wait for parent-teacher conferences
Request a school report for the doctor — it is essential for diagnosis and follow-up
Brazilian Inclusion Law (Lei 13.146/2015) — guarantees reasonable accommodations for children with ADHD in both public and private schools

If the school is flagging difficulties, do not dismiss them. Working with the school — not against it — leads to the best outcomes. When the child also shows speech delay or language difficulties, a speech therapy evaluation complements the investigation.

ADHD and Screens: A Complex Relationship

One of the most frequent questions from parents: “My child can spend hours on a phone/tablet but cannot focus at school. Did screens cause the ADHD?”

What the Science Says

Screens do not cause ADHD — the disorder has a genetic and neurobiological basis
But excessive screen time worsens symptoms — rapid, constant stimulation makes sustained attention harder
“Hyperfocus” on screens is characteristic — children with ADHD can spend hours on games or videos because these stimuli activate dopamine intensely
Screens replace helpful activities — outdoor play, social interactions, and physical activity are protective for attention

The SBP recommends: zero screens until age 2, maximum 1 hour/day from ages 2 to 5, and maximum 2 hours/day above age 6. For children with ADHD, respecting these limits is even more important. When the child is in daycare or school, home screen time should be especially controlled.

When to See the Pediatrician

See your pediatrician if you notice:

!The school frequently reports behavioral issues, inattention, or academic difficulties
!The child cannot complete age-appropriate tasks despite being intelligent
!Restlessness is far above what is expected for the age and is present in multiple settings
!Impulsivity frequently puts the child in risky situations
!You notice your child is suffering — low self-esteem, frustration, difficulty with friendships
!Symptoms have persisted for more than 6 months and do not improve with usual strategies

The Pediatrician's Role

The pediatrician is the first professional to evaluate parental concerns. During the consultation, a developmental assessment will be conducted, other causes will be ruled out (vision problems, hearing issues, common pediatric conditions, sleep disorders), and when necessary, a referral to a neuropediatrician or child psychiatrist will be made. For expat families in Brazil, Dr. Paula provides bilingual care and can coordinate with international schools and specialists. Early diagnosis and proper support make all the differencein a child's trajectory.
