The specific characteristics of culture, age and gender of the patients with ADHD
ADHD is known to occur in every culture, with the circulation of various degrees reported in Western countries, this is probably due to the application of different diagnostic criteria rather than due to differences in clinical manifestations.
The diagnosis is particularly difficult in children less than 4-5 years, because their characteristic behaviors are more fickle than older children and could include other similar to the symptoms of ADHD. Moreover, the symptoms of ADHD decreased in older school age yet often less observed by those little kids at this age usually do not require much attention. However, the ability of the younger children can also be assessed; for example in about 2-3 years older who can sit with an adult and see a book picture. In contrast, small children have the condition ADHD often increase and can hardly be plier. Considering the large number of behaviors in young children can be useful to ensure that the record is a full clinical picture.
When children grow up, the symptoms usually become less clear. Until about the end of childhood and early adolescence, the signs of rudimentary activity (gross motor) (e.g. running jump, climb or excessive, don’t sit still are) will be less probable, and hyperactivity symptoms can be identified by the restlessness or an inner sense of disturbance is not alone. In school-age children, the attention will affect learning ability at school. The chaotic boost expression also led to the breaking of these rules in the home, school and in their social relations, especially in the teens. In adults, the restless status not alone lead to hard to engage in activities and avoiding the pleasures, as well as the limited job opportunities for natural movements (e.g. at work sitting at a desk).
This disorder usually seen in males more than females, with a ratio of males : females range from 4:1 to 9:1 depending on environmental circumstances (e.g. in the general population or in hospitals).
Prevalence of ADHD is estimated at 3-5% of school-age children. In teens and adults, the figures are limited.
