ADHD, or attention-deficit/hyperactivity disorder, is the only clinically diagnosed term for disorders characterized by inattention, hyperactivity, and impulsivity used in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition.
There are actually three different types of ADHD, each with different symptoms: predominantly inattentive, predominantly hyperactive/impulsive, and combined.
This is not a sign of stupidity; in fact, ADD frequently affects those with above average IQ's, such as Ivy League students, and many renowned geniuses throughout history. Though the occasional genuine moron and/or average thinker will fall victim.
A test of whether or not the condition is actual could be if the individual in question has difficulty focusing on the activities they enjoy as well as activities they dislike.
Many critics to the ADD diagnosis say patients are lazy, dumb, bored, and helpless. These people are idiots that fail to realized diversity in our population. They believe that because they can concentrate on tasks that need to be accomplished, everyone else can/should too. They say that people with ADD are lazy and no one likes doing boring daily tasks. They are right in that no one likes doing them, they are wrong in that some people simply can not focus enough to do so.
Everyone has problems. Whether it be mental, physical, etc. Saying a person with ADD is looking for an excuse is like saying a person with an handicap only has one for the sweet parking spot. I will admit, many people take ADD medication for the 'high' they receive, and this is wrong. But MANY drugs are abused, and people that truely have ADD shouldn't be punished. More understanding should be given to people that have been DIAGNOSED with ADD.
