How do teens know if they have ADHD?

Although ADHD begins in childhood, sometimes it's not diagnosed until a person is a teen - and occasionally not even until someone reaches adulthood. Because ADHD is a broad category covering different things - attention, activity, and impulsivity - it can show up in different ways in different people. Some of the signs of ADHD are when someone: * has difficulty paying attention or staying focused on a task or activity * has problems finishing assignments at school or home and jumps from one activity to another * has trouble focusing on instructions and difficulty following through * loses or forgets things such as homework * is easily distracted, even when doing something fun * has problems paying close attention to details or makes careless mistakes * has trouble organizing tasks and activities * has difficulty waiting one's turn * interrupts or intrudes on other people * blurts out answers before questions have been completed * fidgets with hands or feet or squirms about when seated * feels restless * talks excessively and has trouble engaging in activities quietly " THIS INFORMATION WAS EXERTED FROM THIS WEBSITE: http://kidshealth.org/teen/diseases_conditions/learning/adhd.html Well I am a teenager with ADD/ ADHD. You most likely have this if you have trouble focusing, trouble keeping thoughts to yourself, or trouble with school. I used to could never get a paper turned in on time at school and could never focus long enough to even understand the lesson. You may have trouble focussing in class, even if you try you can't even repeat what was said throughout the whole lesson. I know before I started on medicine, I would do so much better if I was able to take a hands on approach to it. One way my doctor had me test it was drink a large Mountain Dew. If it makes you overly hyper you most likely don't have ADHD due to an ingredient in Mountain Dew that acts as a stimulant, for some reason if you do have ADHD it will mellow you out. Hope this helps! But everyone will have some slight differences in symptoms.
