R48: Dyslexia and other symbolic dysfunctions, not elsewhere classified

Dyslexia and other symbolic dysfunctions, not classified elsewhere, cover a range of conditions that affect how a person interprets and understands symbols, such as letters and numbers. Dyslexia, the most common of these conditions, typically impacts reading and writing abilities. People with this condition often confuse letters, read at a slower pace, and struggle with spelling. The cause of dyslexia and symbolic dysfunctions is not entirely known, but these conditions are often connected to the way the brain processes information. Other symbolic dysfunctions can affect a person's ability to understand mathematics, music notation, or other symbol-based systems. Common symptoms of these conditions can vary but often include difficulties in learning, struggles with academic tasks, and frustrations with tasks that require symbolic understanding. These conditions are lifelong and affect numerous aspects of daily life, from schooling to employment and beyond.
