Learning Disabilities in Children: Epidemiology, Risk Factors and Importance of Early Intervention

Abstract

Children with learning disabilities have significant impairment in reading, writing and mathematics, in spite of normal intelligence and sensory abilities. In reading disability, children will have difficulties in phonemic sensitivity, phonetic decoding, word recognition, word decoding skills and reading comprehension. The lifetime prevalence of learning disability is about 10%. Learning disabilities are more frequently seen in boys compared to girls. There are several risk factors for learning disabilities. Low birth weight, preterm birth, neonatal complications, language delay and epilepsy are important risk factors for learning disabilities in children. Students with learning disabilities have poor scholastic performance, anxiety and significant stress. They have more social, emotional and behavioural problems than those without learning problems. If not remedied at the earliest, learning disabilities will lead to failure in exams and these children may develop stress related disorders. Hence all children with learning problems should be evaluated scientifically at the earliest, for identification of learning disability. By providing scientific guidance and intensive one to one remedial training, learning problems of children can be managed successfully.
