What is Learning Disabilities (LD) ?
Learning Disorders are a cluster of several disorders, all of which are related to difficulty in learning. A child with learning disorder may have trouble in one or more of these areas : speaking, reading, writing, reasoning, mathematical ability, listening, language, communication and comprehension. In spite of these, the child will have average intellectual abilities, and may even excel in various other activities, compared to others of his age.
Causes of Learning Disabilities :
GeneticVarious factors influence the process of Learning Disabilities . Throughout pregnancy, the brain develops in order to take up the activities of the growing body. This mass of tissue is vulnerable to disruptions too. If the disruption occurs early, the fetus may die, or the infant may be born with widespread disabilities and possibly mental retardation. If the disruption occurs later, when the cells are becoming specialized and moving into place, it may leave errors in the cell makeup, location, or connections. Some scientists believe that these errors may later show up as learning disorders. Also, the fact that learning disabilities tend to run in families indicates that there may be a genetic link.
Environmental:There may be an alternative explanation for why Learning Disabilities might seem to run in families. Some learning difficulties may actually stem from the family environment. For example, parents who have expressive language disorders might talk less to their children, or the language they use may be distorted. In such cases, the child lacks a good model for acquiring language and therefore, may seem to be learning disabled. Environmental toxins that may lead to learning disabilities, possibly by disrupting childhood brain development or brain processes. Cadmium and lead, both prevalent in the environment, are becoming a leading focus of neurological research. In addition, there is growing evidence that learning problems may develop in children with cancer who had been treated with chemotherapy or radiation at an early age. This seems particularly true of children with brain tumors who received radiation to the skull.
