NARRATOR: What are the differences between dyslexia, dysgraphia, dyscalculia, and dyspraxia? Dyslexia. Dyslexia is a comma learning difficulty that mainly causes problems with reading, writing, and spelling. It's a specific learning difficulty, which means it causes problems with certain abilities used for learning, such as reading and writing. 

Dysgraphia. Dysgraphia is a disorder of writing ability at any stage, including problems with later formation, legibility, letter spacing, spelling, fine motor coordination, rate of writing, grammar, and composition. It can lead to problems with spelling, poor handwriting, and putting thoughts on paper. People with dysgraphia can have trouble organizing letters, numbers, and words on a line or page. 

Dyscalculia. Dyscalculia is a wide range of lifelong learning disabilities involving math. There is no single type of math disability. Dyscalculia can vary from person to person. And it can affect people differently at different stages of life. People with dyscalculia can have visual, spatial difficulties and language-processing difficulties. This means they have trouble processing and understanding what they hear. 

Dyspraxia. Dyspraxia, also known as developmental coordination disorder, is a comma disorder that affects movement and coordination. Dyspraxia does not affect your intelligence. It can affect your coordination skills, such as tasks requiring balance, playing sports, or learning to drive a car.
