Are There Really 7 Types of ADD?

Controversy surrounds Dr. Daniel Amen's 7 types of ADD — each with its own unique ADHD symptoms, brain function, and neurotransmitter activity. Here, the founder of Amen Clinics explains why, after analyzing 20 years of SPECT brain scans, he believes ADHD is a complex condition with multiple sub-types.

Inattentive ADD

This type, as well as Classic ADD, have been described in The Diagnostic and Statistical Manual (DSM) of Mental Disorders since 1980. This type is associated with low activity in the prefrontal cortex and low dopamine levels. Symptoms are short attention span, distractibility, disorganization, procrastination. People with this type are not hyperactive or impulsive. They can be introverted and daydream a lot. Girls have this type as much as, or more than, boys.
