Dysgraphia is a neurological disorder of written expression that impairs writing ability and fine motor skills. It is a learning disability that affects children and adults, and interferes with practically all aspects of the writing process, including spelling, legibility, word spacing and sizing, and expression.Kids with dysgraphia have unclear, irregular or inconsistent handwriting, often with different slants, shapes, upper- and lower-case letters, and cursive and print styles. They also tend to write or copy things slowly.A licensed psychologist trained in learning disorders can diagnose dysgraphia. This could be your child's school psychologist. The specialist will give your child academic and writing tests that measure their ability to put thoughts into words and their fine motor skills.
