Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental condition that affects both children and adults. It is characterized by ongoing patterns of inattention, hyperactivity, and impulsivity that interfere with daily functioning, relationships, and responsibilities.
1. ADHD in Children
ADHD is often first identified in childhood, especially during the school years when challenges with focus, organization, or behaviour become more noticeable. Children with ADHD may struggle to pay attention in class, complete assignments, sit still, or wait their turn. These difficulties go beyond typical childhood behaviour and are more intense than expected for their age.
ADHD presents in three main ways:
-
Predominantly inattentive, involving difficulty focusing, organizing tasks, and following instructions
-
Predominantly hyperactive/impulsive, marked by restlessness and impulsive actions
-
Combined, which includes symptoms of both
A diagnosis requires symptoms to be present for at least six months, begin before age 12, and cause difficulties in more than one setting, such as home and school.
2. ADHD in Adults
Although ADHD is often thought of as a childhood condition, many individuals continue to experience symptoms into adulthood. Some adults are not diagnosed until later in life, especially if their symptoms were less disruptive during childhood.
In adults, hyperactivity may appear as inner restlessness rather than constant movement, while inattention often persists, affecting time management, organization, and work performance. Adults with ADHD may also experience low self-esteem, heightened sensitivity to criticism, and challenges in relationships.
ADHD is recognized as a disability under laws such as the Americans with Disabilities Act (ADA), meaning adults may qualify for reasonable accommodations at work or school.
3. Causes and Diagnosis
There is no single cause of ADHD, but research shows that genetics plays a major role. Differences in brain structure and activity have also been observed. Diagnosis is made through a comprehensive evaluation by a qualified health-care provider and may include interviews, questionnaires, and reports from teachers or family members. There are no blood tests or imaging scans that can diagnose ADHD.
4. Treatment and Support
Treatment typically involves a combination of behavioural strategies, therapy, and medication, depending on age and individual needs. Early support in childhood and continued care into adulthood can significantly improve quality of life.
5. Final Thoughts
ADHD is not a result of laziness or lack of effort. It is a lifelong condition that can affect people differently at various stages of life. With proper understanding, support, and accommodations, individuals with ADHD, both children and adults, can succeed academically, professionally, and socially.
