Attention -deficit/hyperactivity disorder (ADHD) is a neurobehavioral disorder characterized by core symptoms of inattentiveness, distractibility, hyperactivity, and impulsivity. ADHD, previously known as attention deficit disorder or ADD, is thought to be the most common childhood mental health disorder, with estimates of its prevalence in children ranging from 5 to 16 percent; in the U.S., approximately 11 percent of children have been diagnosed with ADHD , per the CDC.

Defining ADHD
ADHD is one of the most studied topics in modern psychology and mental health. At its core, adhd involves a specific cluster of experiences — cognitive, emotional, and physical — that have been consistently identified across cultures and research populations.
Psychologists define adhd using diagnostic criteria that have been refined over decades of clinical and empirical work. The core features include recognizable patterns that distinguish adhd from related but distinct conditions.
Who Does ADHD Affect?
ADHD affects people across all demographics, though certain factors can increase vulnerability:
- Age: Can emerge at any life stage; some forms peak in specific age groups
- Biology: Genetic predisposition plays a role for many types of adhd
- Environment: Life experiences, stress, and social factors contribute significantly
- Co-occurring conditions: ADHD often appears alongside other psychological conditions
The Spectrum of ADHD
Like most psychological phenomena, adhd exists on a spectrum. Mild experiences are part of normal human life. The concern arises when adhd is persistent, intense, and interferes with daily functioning — work, relationships, or basic self-care.
Clinicians assess severity by looking at duration (how long), frequency (how often), and impairment (how much it affects daily life).
When to Seek Help
Consider professional support if adhd:
- Persists for more than a few weeks
- Interferes with work, school, or relationships
- Causes significant distress
- Involves thoughts of self-harm
Getting Help for ADHD
All children benefit from love, structure, and consistency; children with ADHD need all three in droves. Since ADHD symptoms and their resulting academic and social challenges can be damaging to a child’s self-esteem , parents should take steps to find a treatment that works, help the child identify his strengths, and advocate for his needs as he learns to navigate the world on his own. Parents should also help the child set up routines, identify academic strategies that address her specific needs, and learn the social skills necessary in order to form lasting friendships.
