Patient discussion about androstenedione
Q. What is the difference between ADD and ADHD? My Son has been diagnosed with ADD. Is this the same as ADHD?
ADHD: Think of these types of children as the energizer bunnies in constant motion. They tend to move about excessively, fidgeting and squirming, and always into things. Remaining seated when expected to is often an impossible task.
ADD: Children with predominately inattentive behaviors, more commonly referred to as ADD, may act very differently. These are the “daydreamers.” They may appear spacey, forgetful, and distracted. They move from one activity to the next, never quite able to complete a task. Often times they begin a task without waiting for the directions and end up frustrated and uncertain. They may seem rather messy, careless and disorganized.
