Why Can Amphetamines Be Used to Treat
ADHD in Children?
Introduction
Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder
affecting children globally. Characterized by persistent patterns of inattention, hyperactivity,
and impulsivity, ADHD can hinder academic, social, and emotional development.
Amphetamines, a class of stimulant medications, have been widely used as an effective
treatment for ADHD in children. But why are amphetamines suitable for this purpose? This
article delves into the science behind their use, their efficacy, and potential risks.
How Amphetamines Work in ADHD Treatment
Amphetamines are central nervous system stimulants that target specific brain functions to
improve focus and reduce hyperactivity. They primarily affect the neurotransmitters
dopamine and norepinephrine, which play a significant role in attention and impulse control.
1.
Dopamine Regulation
•
Amphetamines increase dopamine levels by facilitating its release and blocking
its reuptake. This boosts communication between neurons, enhancing focus and
reducing impulsivity.
•
Children with ADHD often have dysregulated dopamine pathways, and
amphetamines help normalize this imbalance.
2.
Norepinephrine Modulation
•
By amplifying norepinephrine activity, amphetamines enhance alertness and
sustain attention, enabling children to better manage tasks requiring sustained
focus.
3.
Brain Activation Patterns
•
Functional imaging studies show that amphetamines increase activity in the
prefrontal cortex, the brain region responsible for executive functions such as
planning, organization, and impulse control.
For further insights on amphetamines’ impact on attention deficit hyperactivity disorder, the
Cochrane Library provides a comprehensive review of their application in children and
adolescents. Read more here.
Why Are Amphetamines Effective for ADHD in Children?
The effectiveness of amphetamines in treating ADHD stems from their ability to directly
address the neurological underpinnings of the disorder.
Efficacy in Managing Core Symptoms
•
Clinical studies consistently demonstrate that amphetamines significantly reduce
symptoms of inattention, hyperactivity, and impulsivity in children with ADHD.
•
These medications also enhance children’s ability to perform academically and interact
socially, leading to improved overall quality of life.
Rapid Onset and Sustained Action
•
Amphetamines act quickly, often showing noticeable results within an hour of
administration. Long-acting formulations provide symptom relief throughout the day,
which is beneficial for school-aged children.
Tailored Treatment Options
•
Multiple amphetamine-based medications are available, allowing healthcare providers
to personalize treatment plans based on a child’s unique needs and response to
therapy.

Potential Risks and Considerations
While amphetamines are highly effective, their use requires careful management due to
potential side effects and risks.
Common Side Effects
•
Appetite Suppression: Reduced appetite is a frequently reported side effect, which
can impact growth in some children.
•
Sleep Disturbances: Difficulty falling or staying asleep is another potential issue, often
managed by adjusting dosing schedules.
•
Emotional Changes: Some children may experience mood swings or irritability.
Long-Term Risks
•
Dependency Concerns: Amphetamines have a risk of misuse and dependency. Strict
adherence to prescribed dosages mitigates this risk.
•
Cardiovascular Effects: Rarely, amphetamines may cause increased heart rate or blood
pressure, necessitating monitoring in children with preexisting conditions.
Pregnancy and Future Implications
•
Although primarily focused on children, it is essential to consider the implications of
amphetamine use in pregnant women, as outlined in this review article by Nature.

Comparing Amphetamines with Other ADHD Treatments
Amphetamines are not the only option for managing ADHD. A range of alternatives exists,
including non-stimulant medications, behavioral therapies, and dietary modifications.
Non-Stimulant Medications
•
Drugs like atomoxetine and guanfacine offer symptom relief without the
stimulant-related side effects, though they may take longer to show efficacy.
Behavioral Interventions
•
Cognitive-behavioral therapy (CBT) and parent training programs are integral to a
holistic treatment approach.
Dietary and Lifestyle Adjustments
•
Some evidence suggests that dietary interventions, including omega-3 fatty acid
supplementation, can complement medication.
Amphetamines, however, remain the gold standard for many due to their rapid and reliable
efficacy in reducing ADHD symptoms.
The Future of ADHD Treatment with Amphetamines
As research advances, newer formulations and delivery mechanisms of amphetamines are
being developed to minimize side effects and maximize therapeutic benefits. Innovations
such as transdermal patches and extended-release formulations aim to enhance convenience
and compliance.
FAQs About Amphetamines and ADHD
1. Are amphetamines safe for long-term use in children?Yes, when prescribed and
monitored by a healthcare professional, amphetamines are safe and effective for long-term
ADHD management. Regular check-ups ensure the child’s growth and health are not
adversely affected.
2. How quickly do amphetamines work?Amphetamines typically begin to alleviate
symptoms within 30 to 60 minutes of ingestion.
3. Can amphetamines be combined with other treatments?Yes, they are often used
alongside behavioral therapies and educational interventions for comprehensive ADHD
management.
4. What happens if a child misses a dose?If a dose is missed, consult the prescribing
physician. Avoid doubling doses to make up for the missed one.
5. Are there natural alternatives to amphetamines for ADHD?While some parents explore
natural options like dietary supplements, amphetamines are the most thoroughly researched
and effective treatment for ADHD symptoms.
6. Do all children respond to amphetamines?No, while amphetamines work for most
children with ADHD, a small subset may not respond or may experience intolerable side
effects, requiring alternative treatments.
Conclusion
Amphetamines have proven to be a cornerstone in the treatment of ADHD in children,
offering rapid and effective symptom relief. Their ability to modulate key neurotransmitter
systems makes them particularly well-suited to addressing the core challenges of ADHD.
However, their use requires careful oversight to manage potential risks. As research
continues, the future holds promise for even more refined and effective ADHD treatments.
