Learning disabilities are problems that affect the brain’s ability to receive, process, analyze, or store information. The most common and best-known verbal learning disability is dyslexia(诵读困难), which causes people to have trouble recognizing or processing letters and the sounds associated with them. Learning disabilities make up at least 10 percent of the population at present.

People with learning disabilities have average or above-average intelligence, but their difficulties in managing the information their brains receive hold them back in school and at work, causing problems with self-esteem(自尊). One of the most painful aspects of having a learning disability is to have your brain’s inability to process information in certain ways mistaken for low intelligence. The disability usually only affects certain limited areas of a child’s development. In fact, rarely are learning disabilities severe enough to influence a person’s potential to live a happy, normal life.

Causes of learning disabilities are various. Environmental factors, complications during pregnancy, genetic influences, CNS(Central Nervous System) infections are all possible factors. Signs of learning disabilities may vary from person to person. Some have difficulty in speaking, spelling, listening or understanding; some can’t recognize words previously learned and others may have problems with math, direct attention or physical coordination(协调).

Diagnosis(诊断)includes intellectual, educational, speech and language, medical, and psychological evaluations. The important thing is to follow up on any concerns, whether you notice something wrong at home or a teacher raises a red flag. A specialist in learning disabilities may not be as knowledgeable about other conditions that may contribute to learning difficulties. For the diagnosis of learning difficulties, IQ test can be taken which will give the results of learning disabilities. The specialist will test sensory disorders that can lead to learning problems.

The good news about learning disabilities is that while they’re permanent, they’re also treatable. Learning disabilities fall within the class of Neurological(神经学的)issues called developmental disabilities, in which they limit success in one or more major life areas, and they can’t be reversed(彻底转变)by meditation. Among these sources are doctors, special education, teachers and mental health professionals who can help identify learning disabilities and recommend the right combination of medical, psychological, and educational treatment.
