Abstract

The early identification of the attention deficit hyperactivity disorder (ADHD) allows the implementation of effective therapies; this fact causes the study of the etiology of the disorder and the associated characteristics during infancy and childhood. The data was gathered through a clinical questionnaire of the ADHD for parents. The subjects were ten mothers aged in average 32 years. The results show that the disorder is hereditary and besides, there are risk factors during pregnancy and birth. The associated characteristics of ADHD during infancy and childhood are a level of activity above the average, restless sleep, quiet insistent to ask for something, normal gross motor development, poor fine motor coordination, greater risk of accidental injury, slightly premature development of language, fair academic progress, repetition of a grade, involvement in special education programs, difficulty in keeping friends and poor rule-governed behavior.
