Are ADD and ADHD the same?

Yes, they are the same thing. In 1987 the "hyperactivity" component was added to ADD, which became known as ADHD. Attention Deficit Hyperactive Disorder can be described into three different types.

1. Combined type: this is the most common type and is characterized by impulsive and hyperactive behaviors, inattention, and distractibility.
2. Impulsive, hyperactive type: this is the least common and is characterized by impulsive and hyperactive behaviors without the presence of inattention and distractibility.
3. Inattentive and distractible type: characterized by inattention and distractibility without hyperactivity.
