Attention deficit hyperactivity disorder (ADHD).اختلال بیش فعالی و فقدان توجه

Attention deficit hyperactivity disorder
Attention deficit hyperactivity disorder (ADHD) is a developmental disorder characterized by inattention, hyperactivity, and impulsivity. It is the most commonly diagnosed behavioral disorder of childhood, affecting 8 - 12% of school-aged children. Although many people sometimes have difficulty sitting still, paying attention, or controlling impulsive behavior, people with ADHD find that these symptoms greatly interfere with everyday life. Generally, these symptoms appear before age 7 and can lead to problems in school and in social settings. One- to two-thirds of all children with ADHD continue to have symptoms when they grow up. A diagnosis can be controversial, since there are no lab tests for ADHD, and no objective way to measure a child's behavior. There is no best way to treat ADHD, however, experts agree that taking action early can improve a child's educational and social development.


اختلال بیش فعالی و فقدان توجه، یک اختلال رفتاری شایع است که حدود 10-8 درصد کودکان را مبتلا می کند. احتمال تشخیص این اختلال در پسران سه برابر دختران است ولی علت این تفاوت هنوز مشخص نشده است. کودکان بیش فعال بدون فکر کردن عمل می کنند، بیش از اندازه فعالند و در تمرکز کردن مشکل دارند.
