Attention-Deficit/Hyperactivity Disorder, commonly known as ADHD, is one of the most frequently discussed neurodevelopmental conditions in both children and adults. Despite its prevalence, many people still wonder: What causes attention deficit hyperactivity disorder? The answer is not completely straightforward. Rather than stemming from a single factor, ADHD is influenced by a complex interplay of genetics, brain development, environmental influences, and early life experiences.
Understanding the causes of ADHD is important not only for those diagnosed but also for caregivers, educators, health professionals, and anyone who interacts with children or adults who struggle with attention, organization, impulsivity, or hyperactivity. With proper understanding, support becomes easier, stigma decreases, and individuals can receive appropriate intervention from qualified professionals, including a psychiatrist in Los Angeles or specialists trained in child and adolescent psychiatry.
This article explores the roots of ADHD, the biological and environmental factors involved, the importance of early diagnosis, and how organizations like Brain Health USA support those seeking help.
Understanding ADHD: A Brief Overview
Before exploring the causes of attention-deficit/hyperactivity disorder, it’s important to understand what ADHD actually is. ADHD is a neurodevelopmental condition that affects attention, impulse control, cognitive regulation, and sometimes physical activity levels. Core symptoms typically fall under three categories:
- Inattentiveness
- Hyperactivity
- Impulsivity
Symptoms vary widely between individuals. Some show primarily inattentive traits, others show hyperactive traits, while many experience a combined pattern. A specialist in child and adolescent psychiatry or a qualified psychiatrist in Los Angeles can accurately determine the specific type and severity.
Genetics: The Leading Cause of ADHD
When asking, “what causes attention-deficit/hyperactivity disorder?” genetics stands out as one of the strongest contributors. Research consistently shows that ADHD tends to run in families. If a child is diagnosed with ADHD, there is a higher likelihood that a biological parent or sibling may share similar traits or symptoms.
How Genetics Influence ADHD
Certain genes influence how neurotransmitters—especially dopamine and norepinephrine—function in the brain. These chemicals play a critical role in attention, motivation, reward processing, and the ability to regulate behavior.
Genetic influence doesn’t guarantee that someone will develop ADHD. Instead, it increases susceptibility. Environmental experiences and brain development also shape the expression of these traits.
Brain Structure and Neurochemistry
Another major factor in what causes attention-deficit/hyperactivity disorder involves the physical structure and functioning of the brain. Advances in neuroimaging have revealed that certain brain regions play a role in ADHD symptoms, particularly those involved in:
- Decision-making
- Impulse control
- Emotional regulation
- Planning and organization
- Sustained attention
Differences Observed in Brain Scans
Studies reveal that some individuals with ADHD may have variations in:
- The size of specific brain regions that manage executive functions
- Neural connections are responsible for focus and communication between brain areas
- Neurotransmitter levels, especially dopamine pathways
These differences do not imply damage or deficiency, but rather variation. A skilled psychiatrist in Los Angeles can determine how these differences relate to observable symptoms and create a treatment plan that supports improved functioning.
Environmental Factors and Their Influence
While genetics and brain structure hold strong influence, several environmental factors may contribute to the development or worsening of ADHD symptoms.
Prenatal and Early Development Factors
Research suggests that the following may slightly increase the likelihood of ADHD:
- Maternal stress during pregnancy
- Premature birth
- Low birth weight
- Prenatal exposure to certain environmental toxins
These factors do not directly cause ADHD, but can influence brain development during critical periods.
Childhood Environmental Influences
Factors that may affect symptom expression include:
- Chronic stress
- Lack of routine or structure
- Exposure to secondhand smoke
- Environmental toxins such as lead
Again, these do not cause ADHD alone, but may intensify difficulties in children already predisposed to the condition.
Social and Behavioral Contributors
While ADHD is not caused by parenting style, certain social and behavioral factors can influence how symptoms appear or intensify. For example:
- Chaotic environments
- Inconsistent discipline
- Overstimulation
- Academic or social pressure
These factors can exacerbate attention difficulties or impulsive behaviors. Specialists in child and adolescent psychiatry often work with families to create structured routines, develop positive reinforcement strategies, and provide guidance on emotional and behavioral regulation.
The Role of Childhood Development
ADHD symptoms often become noticeable during early school years, when children face increasing demands for organization, focus, and self-control. Early development plays a significant role because:
- Some children develop executive functioning skills more slowly
- Wiring between brain regions strengthens at different rates
- Emotional regulation skills mature at varying times
Symptoms may appear mild during preschool years, only becoming more noticeable when academic expectations rise. A qualified psychiatrist in Los Angeles can assess developmental patterns to determine if behaviors align with ADHD or another condition.
Misconceptions About ADHD Causes
When understanding what causes attention-deficit/hyperactivity disorder, it is also helpful to clear up popular misconceptions.
Myths That Do Not Cause ADHD
ADHD is not caused by:
- Poor parenting
- Lack of discipline
- Too much sugar
- Watching excessive television
- Laziness or lack of intelligence
Such misconceptions can lead to stigma and misunderstanding. ADHD is a legitimate neurodevelopmental condition requiring appropriate evaluation and support.
How a Psychiatrist in Los Angeles Can Help
A Psychiatrist in Los Angeles plays a crucial role in diagnosing and treating ADHD. Their approach may include:
- Comprehensive evaluation
- Clinical interviews
- Developmental history review
- Behavioral assessments
- Individualized treatment planning
Treatment may combine structured therapy, skill-building strategies, and sometimes medication. For children, the involvement of professionals trained in child and adolescent psychiatry ensures that interventions are tailored to developmental needs.
Adults also benefit from specialized care, as ADHD can impact work performance, relationships, and daily responsibilities. Modern treatment strategies focus on helping individuals build executive functioning skills, manage emotions, and improve life balance.

Frequently Asked Questions (FAQ)
- Can ADHD be prevented?
While ADHD cannot be fully prevented due to its strong genetic components, healthy prenatal care and a supportive environment can reduce certain risks. - Does ADHD go away with age?
Symptoms can improve as individuals develop, but ADHD often continues into adulthood. Many adults learn effective coping strategies that help manage daily functioning. - How does a psychiatrist in Los Angeles diagnose ADHD?
Diagnosis typically includes clinical interviews, behavioral assessments, review of symptoms, developmental history, and sometimes psychological testing. - Is medication required for ADHD?
Medication is not mandatory. Treatment may include behavioral therapies, skill-building strategies, lifestyle adjustments, and structured routines. Some individuals benefit from medication, while others do well without it. - Can ADHD exist without hyperactivity?
Yes. Inattentive-type ADHD features difficulty with focus and organization but may not involve hyperactivity. A specialist trained in child and adolescent psychiatry can determine the specific type.
