According to the Amerian Psychatric Association's Diagnostic and Statistical Manual of Mental Disorders, attention deficit hyperactivity disorder (ADHD) is classified as having three major subtypes: predominately hyperactive-impulsive, predominately inattentive, and combined inattentive/hyperactive-impulsive.  Many people still use the term “ADD”— which stands for attention deficit disorder—to describe the predominately inattentive ADHD subtype.  We have chosen to display the words of our contributors as they were told to us and not made any changes to how our contributors chose to describe their experiences with ADHD.
