Adults too can get ADHD. In the case of children, the symptoms of ADHD are quite visible. But the symptoms in adults are quite subtle. This means  many adults struggle with ADHD. Adults, in many cases do not know they have ADHD. The reasons for adult ADHD are may or may not be the reasons like spending more time before the Computer. But here are some of the reasons for adult ADHD.

A history of not doing well in school and under achieving, gotten in a lot of trouble, had to report a grade, dropped out of school etc.

Wel, I do agree this ADHD problem will surely occur and may already occurred in present children who always stressed with studies by parents and school teachers. The life of children has become in such a way that wherever they go only study. The best time for them to enjoy is till 2 years of their age. as now a days parents are making them start studies from 2 and half years. They say its prep and then in third year nursery. then the serious studies starts and this ends at 25 age. Till then they will be full of stress of studying and reaching their goals. Early morning parents make their wake around 4'oclock and force them study and then again around 8 they goto school and there again teachers make them study and after coming home parents send them to tutions again there in tution children study. may be around 8 they come home. again parents make them study and then 10 will be the time and then they go to bed. so place for refreshment and games. This is really horrible i feel. Parents should take care of their children not only in studies but also about their children refreshment by making them play or sending out to play for better relaxant etc. If we continuously make children study then they get bored of and at such situation the children will get ADHD problems.

Researchers say, increased academic activities  since 1970s have contributed in a big way to the rise in diagnosis of ADHD. So, its no surprise  that along with the increased academic activities, time for playing and leisure decreased, resulting in some children being seen as outliers and ultimately being diagnosed with ADHD.
