Attention Deficit Disorder or ADD is a very complicated, and time and again misinterpreted, disorder. Its beginning is physiological, but it can have a multitude of consequences that come alongside with it. That apart, what is the differentiation between ADHD and ADD? ADHD is the abbreviated form of Attention Deficit Hyperactive Disorder, its major indications being noticeable hyperactivity and impulsivity. These are the indications that are noticeable to the purposeful onlooker. ADD stands for Attention Deficit Disorder with the major indications being lack of concentration. Now a lot of other things can come alongside with both of these subtypes of ADHD, but those are the distinctive characteristics of both.For several years, the usual picture of Attention Deficit Disorder has been the little boy that is bouncing off the walls and making his teachers and parents go mad. ADHD is beyond a doubt the more identifiable of the two subtypes since it is so much more noticeable than ADD. Since hyperactivity causes a lot more disruption and problems for classrooms, it gets the most notice and will be picked up on a lot quicker. Unluckily, even if ADD is less visible, the consequences of the disorder can just as negative.With negligent attention deficit disorder, or ADD, the person enduring it will give the impression of being spacey and disordered. More often, victims with this type will be gazing out of the window during classes and will seem as if they are never somewhat there. It is much more tricky to make a diagnosis and a lot of people with this form of ADD go years without even knowing they have it. But the consequences of the drifting mind can be just as disparaging.
