This behavioural feature is most evident in structured, organized situations that require a high degree of behavioural self-control. The standard for judgement should be that the activity is excessive in the context of what is expected in the situation and by comparison with other children of the same age and IQ. It may, depending upon the situation, involve the child running and jumping around, getting up from a seat when he or she was supposed to remain seated, excessive talkativeness and noisiness, or fidgeting and wriggling. Overactivity implies excessive restlessness, especially in situations requiring relative calm. These deficits in persistence and attention should be diagnosed only if they are excessive for the childвЂ™s age and IQ.

The children change frequently from one activity to another, seemingly losing interest in one task because they become diverted to another (although laboratory studies do not generally show an unusual degree of sensory or perceptual distractibility). Impaired attention is manifested by prematurely breaking off from tasks and leaving activities unfinished. The cardinal features are impaired attention and overactivity: both are necessary for the diagnosis and should be evident in more than one situation (e.g. Associated reading difficulties (and/or other scholastic problems) are common. Hyperkinetic disorders are several times more frequent in boys than in girls. Nevertheless, current evidence favours the separation of a group in which hyperkinesis is the main problem. There is accordingly considerable overlap between hyperkinesis and other patterns of disruptive behaviour such as вЂњunsocialized conduct disorderвЂќ. Secondary complications include dissocial behaviour and low self-esteem. Cognitive impairment is common, and specific delays in motor and language development are disproportionately frequent. Their relationships with adults are often socially disinhibited, with a lack of normal caution and reserve they are unpopular with other children and may become isolated. Hyperkinetic children are often reckless and impulsive, prone to accidents, and find themselves in disciplinary trouble because of unthinking (rather than deliberately defiant) breaches of rules. Several other abnormalities may be associated with these disorders. Try Online Counseling: Get Personally Matched (Please read our important explanation below.) These problems usually persist through school years and even into adult life, but many affected individuals show a gradual improvement in activity and attention. Their chief characteristics are lack of persistence in activities that require cognitive involvement, and a tendency to move from one activity to another without completing any one, together with disorganized, ill-regulated, and excessive activity. Hyperkinetic disorders always arise early in development (usually in the first 5 years of life).

However, it is clear that, from the point of view of behaviour, problems of inattention constitute a central feature of these hyperkinetic syndromes. It has not been used here because it implies a knowledge of psychological processes that is not yet available, and it suggests the inclusion of anxious, preoccupied, or вЂњdreamyвЂќ apathetic children whose problems are probably different. In recent years the use of the diagnostic term вЂњattention deficit disorderвЂќ for these syndromes has been promoted. It is widely thought that constitutional abnormalities play a crucial role in the genesis of these disorders, but knowledge on specific etiology is lacking at present. This group of disorders is characterized by: early onset a combination of overactive, poorly modulated behaviour with marked inattention and lack of persistent task involvement and pervasiveness over situations and persistence over time of these behavioural characteristics.
