“Predominantly inattentive type
Perhaps the majority of girls with AD/HD fall into the primarily inattentive type, and are most likely to go undiagnosed. Generally, these girls are more compliant than disruptive and get by rather passively in the academic arena. They may be hypoactive or lethargic. In the extreme, they may even seem narcoleptic. Because they do not appear to stray from cultural norms, they will rarely come to the attention of their teacher.
Early report cards of an inattentive type girl may read, "She is such a sweet little girl. She must try harder to speak up in class." She is often a shy daydreamer who avoids drawing attention to herself. Fearful of expressing herself in class, she is concerned that she will be ridiculed or wrong. She often feels awkward, and may nervously twirl the ends of her hair. Her preferred seating position is in the rear of the classroom. She may appear to be listening to the teacher, even when she has drifted off and her thoughts are far away. These girls avoid challenges, are easily discouraged, and tend to give up quickly. Their lack of confidence in themselves is reflected in their failure excuses, such as, "I can't," "It's too hard," or "I used to know it, but I can't remember it now."
The inattentive girl is likely to be disorganized, forgetful, and often anxious about her school work. Teachers may be frustrated because she does not finish class work on time. She may mistakenly be judged as less bright than she really
is. These girls are reluctant to volunteer for a project orjoin a group of peers at recess. They worry that other children will humiliate them if they make a mistake, which they are sure they will. Indeed, one of their greatest fears is being called on in class; they may stare down at their book to avoid eye contact with the teacher, hoping that the teacher will forget they exist for the moment.
Because interactions with the teacher are often anxiety-ridden, these girls may have trouble expressing themselves, even when they know the answer. Sometimes, it is concluded that they have problems with central auditory processing or expressive language skills. More likely, their anxiety interferes with their concentration, temporarily reducing their capacity to both speak and listen. Generally, these girls don't experience this problem around family or close friends, where they are more relaxed.
Inattentive type girls with a high IQ and no learning disabilities will be diagnosed with AD/HD very late, if ever. These bright girls have the ability and the resources to compensate for their cognitive challenges, but it's a mixed blessing. Their psychological distress is internalized, making it less obvious, but no less damaging. Some of these girls will go unnoticed until college or beyond, and many are never diagnosed they are left to live with chronic stress that may develop into anxiety and depression as their exhausting, hidden efforts to succeed take their toll.
