What is ADHD? ADHD stands for Attention-Deficit/Hyperactivity Disorder. It is a neurodevelopmental condition that affects how the brain manages attention, impulse control, and activity levels. In simple terms, ADHD makes it harder for a person to focus, sit still, plan ahead, or control impulsive reactions — not because they aren’t trying, but because their brain is wired to process attention and self-control differently. ADHD is not a result of laziness, poor parenting, or lack of discipline. It is a genuine, well-researched medical condition that affects both children and adults, and it can influence school performance, work life, relationships, and everyday routines. Who Does ADHD Affect? ADHD is often thought of as a “childhood condition,” but that’s a myth. While it is usually first noticed in childhood, ADHD frequently continues into the teenage years and adulthood. Many adults are diagnosed later in life, often after recognising the same patterns in their own children.
