I have learned in Human Development class that males outnumber females by a 3:1 ratio
ADHD is more commonly diagnosed and treated in kids. Aside from this, both children and adults generally manifest the disease in a very similar fashion.
he was diagnosed at 9 years of age
It is estimated that around 6.4 million children have been diagnosed with attention-deficit/hyperactivity disorder (ADHD) in the United States. It is one of the most common neurodevelopmental disorders in children.

According to some sources, ADD and ADHD affect somewhere between 3% and 5% of all children. It actually gets diagnosed in up to 16% of all school aged children, which suggests that it may be over-diagnosed. While the conventional belief for years was that a person would "outgrow" it, more recent research suggests that up to 50% of children with it will continue to have symptoms into adulthood. Since behavior modification has been shown to be an effective component in treatments with ADD/ADHD, it is quite possible that the reason more adults who were diagnosed with ADD/ADHD as kids don't show symptoms as adults is that they learned to cope with it, not that it went away. It has also been noted genetics seems to play a role in ADD/ADHD. Close relatives of people with ADD/ADHD are much more likely to also have ADD/ADHD than the general population. Males are roughly 2 to 3 times as likely to be ADD/ADHD as females. The gender difference may be due to higher susceptibility of males to ADD/ADHD or just a result of females being less likely to be diagnosed.
You don't "get" ADD/ADHD therefore it's not a concern. There is however a degree of heritability in diagnoses of ADD/ADHD so children of parents with that diagnosis may be more likely to be diagnosed with the disorder.
Not necessarily. hyperactivity is a part of ADHD but hyperactivity it self is not adhd. This must be diagnosed by a medical professional and the subject may have adhd or is just a hyper type of person.
