androstenedione
An androgenic steroid less potent than testosterone, which is produced by the adrenal cortex, ovary and testis and converted to estrone in fat and the liver; in men, overproduction of androstendione may cause feminisation.
Increased in Cushing syndrome; ovarian, testicular or adrenocortical tumours; adrenal hyperplasia; polycystic ovary disease. Decreased in Hypogonadism, Addison’s disease.

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?A. Here is the general description: 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.
Q. Is there any connection between ADD and Autism? I refer to ADD, not ADHDA. there is a theory that ADD and learning disabilities are a "continuum" up to Asperger syndrome and autism. due to similarities in brain function and symptoms. mind you- it's a theory.
Q. What is the difference between ADD and ADHD? I know that H stands for hyperactivity, but what does it mean by symptoms? does It have the same treatment?A. They differ by ADHD kids tend to move around all the time (not like ADD who can sit but not listen), and they are more then careless. They tend to injure themselves over childhood. I saw a nice video that explains about those disorders!
