## **Core Concept**
Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity. It is more commonly diagnosed in boys than girls, but girls are more likely to have the **inattentive subtype**. The subtypes of ADHD include predominantly hyperactive-impulsive type, predominantly inattentive type, and combined type.

## **Why the Correct Answer is Right**
The correct answer, , refers to the predominantly inattentive type (PIT) of ADHD. This subtype is characterized by symptoms of inattention, such as difficulty sustaining focus, following detailed instructions, and completing tasks. Girls with ADHD are more likely to exhibit inattentive symptoms rather than hyperactive-impulsive symptoms, which are more commonly seen in boys. The inattentive subtype can often go unnoticed until later in childhood or even in adolescence, as the symptoms may not be as disruptive as those seen in the hyperactive-impulsive type.

## **Why Each Wrong Option is Incorrect**
* **Option A:** This option does not correspond to the correct subtype of ADHD common in girls.
* **Option B:** This option also does not represent the subtype predominantly found in girls.
* **Option D:** Similarly, this option is incorrect as it does not denote the inattentive subtype.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that girls with ADHD are more likely to be diagnosed with the **predominantly inattentive type**. This subtype can sometimes be overlooked, as the symptoms may not be as overtly disruptive as those seen in other subtypes. Clinicians should maintain a high index of suspicion for ADHD in girls who present with difficulties in academic performance or organizational skills.

## **Correct Answer:** . predominantly inattentive type
