Dyslexic

n.
A person who is affected by dyslexia.

Adj.
Of or relating to dyslexia.

Generally, the term dyslexia is used to describe a severe reading disability, but there has been little agreement in the literature or in practice concerning the definition of severe or the specific distinguishing characteristics that differentiate dyslexia from other reading problems.

Due to the variety of definitions, many professionals have resisted using the term at all. Instead, they have used such terms as "reading disability" or "learning disability" to describe conditions more correctly designated as dyslexia.

Although there is no universally recognized definition of dyslexia, the one presented by the World Federation of Neurology has won broad respect: "A disorder manifested by difficulty in learning to read despite conventional instruction, adequate intelligence and sociocultural opportunity."
