Case-study of a three-year-old boy with visual impairment The aim of the work is to present a clinical study of a development path using the theoretical model of developmental pathways (Pickles, Hill, 2006). The subject of the study, a three-year-old boy, came into the world through complicated labor which ended in cesarean section. He displayed characteristics of insecure-avoidant attachment. Moreover, he had a visual defect. The study describes the crisis at the beginning of preschool education. Adaptive irregularities arising from these burdens, but also the lack of competence and support from the preschool staffmeant that the boy began to show features of mental disorders functioning. At this time independent specialists diagnosed mental retardation and attention defi cit with hyperactivity disorder. Through correcting the vision problems, working on the relationship, changing the preschool facility and introducing cognitive-behavioral techniques the abnormal development of the boy returned onto the correct track. The aim of the work is to show the path of corruption in the development of mental disorder in the three-year-old boy. The developmental pathways approach takes into account the role of a wide range of internal factors (biological, social and psychological) as well as external ones – environmental and those concerning the effect of time and place, both in the development of pathology, and in turning to pathology as a way to return to normal development
