All definitions of dyslexia mention severe reading and/or spelling problems. Is this enough for the diagnosis of dyslexia or should we include other cognitive abilities? Two issues will be discussed.  First, some definitions also include the presumed cognitive causes of dyslexia. Is there sufficient evidence to do this? Secondly, definitions of dyslexia hardly ever contain contraindications except for exclusionary criteria such as poor education. However, it is known that malingering happens. Can malingerers be recognized? It will be concluded that reading and spelling are (almost) the only abilities that need to be assessed for diagnosing dyslexia.
