ADD

ADHD predominantly inattentive (ADHD-PI or ADHD-I) is one of the three subtypes of Attention-deficit hyperactivity disorder (ADHD). While ADHD-PI is sometimes still called "attention deficit disorder" (ADD) by the general public, these older terms were formally changed in 1994 in the new

Attention Deficit Disorder, or ADD/ADHD, is a psychological term currently applied to anyone who meets the DSM IV diagnostic criteria for impulsivity, hyperactivity and/or inattention.  The diagnostic criteria are subjective and include behavior which might be caused by a wide variety of factors, ranging from brain defects to allergies to giftedness.  ADD, as currently defined, is a highly subjective description, not a specific disease. 
Confusion and controversy is caused by the tendency of some mental health professionals to assume that everyone diagnosed with ADD has some mysterious, irreversible brain defect.  This assumption has its roots in the very first group of severely ADD people ever studied, who suffered from encephalitis, or a swelling of the brain.  We also have learned that birth defects and brain injury from toxic chemicals such as lead often cause ADD.  However, over the last several decades the ADD diagnostic criteria have been so broadened as to include many people with no brain defects at all. Experts in the fields of temperament and creativity have objected that perfectly healthy people are being classified as disordered.  Huge numbers of these new types of people being added to the diagnostic pot have changed the way ADD is viewed in some circles, including people like Thom Hartmann, who popularized the idea of ADDers being "Hunters in a Farmer's World".  On the other hand, many argue that such people aren't ADD in the first place.  Both may be correct.  This website was started with the first viewpoint in mind (hence the title), but as time passes I find myself more likely to just say that many so-called ADD people are simply not ADD in the classic sense.

There are two major types of ADD at this time (this aspect of ADD keeps evolving): ADD with hyperactivity (the traditional type of ADD) and ADD without hyperactivity ("inattentive" type). Here are the DSM IV diagnostic criteria in a condensed form:
Inattention (must meet six of the following to a degree that is "maladaptive"):

• Often fails to give close attention to details or makes mistakes in schoolwork;
• difficulty sustaining attention in tasks;
• seems not to listen;
• fails to follow instructions or finish work;
• unorganized;
• difficulties with schoolwork or homework;
• loses things like school assignments, books, tools, etc.;
• easily distracted;
• forgetful about daily activities.

ADD with Hyperactivity (must meet six of the following to a degree that is "maladaptive"): 

• fidgety in a squirmy sense;
• doesn't stay seated;
• runs or climbs excessively (or feelings of restlessness in older children);
• difficulty playing quietly;
• often "on the go" or acts if "driven by a motor";
• often talks excessively;
• blurts out answers to questions;
• difficulty waiting in lines or waiting turns;
• often interrupts or intrudes on others.

Technically, ADD is not something you can suddenly come down with.  "Symptoms" such as excessive daydreaming or hyperactivity must be present by the age of seven in two or more settings and cannot be explained by some other psychological condition such as depression or anxiety.  However, there are cases of people acquiring the symptoms of ADD after experiencing brain trauma.
I will mention the "Lego Test" here.  For boys in particular, some professionals say that if a child can stay highly focused and on-task when it comes to following Lego directions, then he is not actually ADD.  This is, of course, not part of any official diagnostic manual and others would dispute it.
There is no exclusion for behavior caused by giftedness, normal temperament diversity, allergies or fatty acid deficiencies.  If you meet the criteria, then you are ADD, even if your behavior is the result of having an IQ of 175 and being confined to a dull school.  Behavior cannot be caused by some other psychological condition, however, such as depression or anxiety.
