ADD or ADHD must be evaluated and treated separatelyfrom the learning disability. Learning disabilities are lifelong conditions that may require special understanding and help throughout grade school, high school, and beyond. They are also life disabilities that have important effects outside of the classroom, interfering not only with academic work but also with children's games, daily activities, and even friendships. Therefore, help for these children means more than classroom special education. By the late 1960s, the present model of learning disabilities was established.
Input is the process of recording in the brain information that comesfrom the senses.
Integration is the process of interpreting this information. Memory is its storage for later retrieval. Learning disabilities can be classified by their effects at one or more of these stages. Each child has individual strengths and weaknesses at each stage. The first major type of problem at the input stage is a visual perception disability.
