You are probably familiar with the term ADHD (Attention Deficit and Hyperactivity Disorder). But not everyone with ADHD is hyperactive. In fact, ADHD can be a misleading term. Depending on which parts of the brain are affected, ADHD is currently diagnosed in three different forms:

1. The predominantly inattentive type, commonly referred to as ADD (Attention Deficit Disorder).
2. The predominantly hyperactive-impulsive type.
3. The combined inattentive and hyperactive/impulsive type.

1. Selective attention
2. Sustained attention
3. Impulse control
4. Psychomotor activity.
