It’s normal for children to occasionally forget their homework, daydream during class, act without thinking, or get fidgety at the dinner table. But inattention, impulsivity, and hyperactivity are also signs of attention deficit hyperactivity disorder (ADHD), sometimes known as attention deficit disorder or ADD. ADHD is a common neurodevelopmental disorder that typically appears in early childhood, usually before the age of seven. ADHD makes it difficult for children to inhibit their spontaneous responses—responses that can involve everything from movement to speech to attentiveness. We all know kids who can’t sit still, who never seem to listen, who don’t follow instructions no matter how clearly you present them, or who blurt out inappropriate comments at inappropriate times. Sometimes these children are labeled as troublemakers, or criticized for being lazy and undisciplined. However, they may have ADHD. When many people think of attention deficit disorder, they picture an out-of-control kid in constant motion, bouncing off the walls and disrupting everyone around. But the reality is much more complex. Some children with ADHD are hyperactive, while others sit quietly—with their attention miles away. Some put too much focus on a task and have trouble shifting it to something else. Others are only mildly inattentive, but overly impulsive. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones.
