Dyslexia and other learning disabilities have so many symptoms in common that it is difficult to know initially whether a person is suffering from dyslexia or some other learning disability. ADD or attention-deficit disorder has much in common with dyslexia in that both involve short attention span and inability to concentrate on something one at a time. Dyslexics too have to struggle with concentration and poor memory. Dyscalculia is another learning disability in which a person is unable to perform basic mathematical problems and is very similar to dyslexics struggling with sequencing and numbers. Many children also have similar learning problems due to emotional disturbances, delayed learning, change of school, autism and a dyslexia screening test helps weed out possible dyslexics from others.

General dyslexia signs include having a tough time in learning letters and sounds, memorizing numbers, learning names, remembering instructions, writing clearly, managing time and reading. Dyslexia reading can really hamper a person’s life as one has to constantly read everywhere. So, someone having a lot of learning problems can go in for a screening test initially. A dyslexic screening test consists of questions like whether there is any difficulty with spelling, reading or numbers and following directions or is there a marked reluctance to go to school. It is also very useful for researchers as they can focus on probable dyslexic children. A screening test for dyslexia is not conclusive but it helps to narrow down those who might need a more thorough dyslexic diagnostic test.
