Overview of attention deficit hyperactivity disorder in young children

Attention deficit hyperactivity disorder (ADHD) is a complex disorder, which can be seen as a dis order of life time, developing in preschool years and manifesting symptoms (full and/or partial) throughout the adulthood; therefore, it is not sur prising that there are no simple solutions. The aim of this paper is to provide a short and concise review which can be used to inform affected chil dren and adults; family members of affected chil dren and adults, and other medical, paramedical, non-medical, and educational professionals about the disorder. This paper has also tried to look into the process of how ADHD develops; what are the associated problems; and how many other children and adults are affected by such problems all over the world basically to understand ADHD more pre cisely in order to develop a better medical and or non-medical multimodal intervention plan. If pre school teachers and clinicians are aware of what the research tells us about ADHD, the varying the ories of its cause, and which areas need further research, the knowledge will assist them in sup porting the families of children with ADHD. By including information in this review about the con nection between biological behavior, it is hoped that preschool teachers and clinicians at all levels will feel more confident about explaining to par ents of ADHD children, and older ADHD children themselves about the probable causes of ADHD.
