A person who struggles with organization of numbers, has trouble with counting principles, or has difficulty telling time may have Dyscalculia. Dyscalculia is a specific learning disability that affects a person's ability to understand numbers and learn math facts. Unlike Dyscalculia, Dysgraphia affects writing skills, Dysphagia involves difficulty in swallowing, and Dyspraxia includes impairments in coordination and motor skills.
