Dysgraphia is a specific learning
disability that affects written expression.
Dysgraphia can appear as
difficulties with spelling, poor handwriting and trouble putting thoughts on
paper. Dysgraphia can be a language based, and/or non-language based disorder.
Many people have poor
handwriting, but dysgraphia is more serious. Dysgraphia is a neurological
disorder that generally appears when children are first learning to write.
Experts are not sure what causes it, but early treatment can help prevent or
reduce problems.
Writing requires a complex
set of motor and information processing skills. Not only does it require the
ability to organize and express ideas in the mind. It also requires the ability
to get the muscles in the hands and fingers to form those ideas, letter by
letter, on paper.
Dysgraphia
that is caused by a language disorder may be characterised by the person having
difficulty converting the sounds of language into written form (phonemes into
graphemes), or knowing which alternate spelling to use for each sound. A person
with dysgraphia may write their letters in reverse, have trouble recalling how
letters are formed, or when to use lower or upper case letters. A person with dysgraphia
may struggle to form written sentences with correct grammar and punctuation,
with common problems including ommitting words, words ordered incorrectly,
incorrect verb and pronoun usage and word ending errors. People with dysgraphia
may speak more easily and fluently than they write.
Non-language
based dysgraphias are those caused by difficulties performing the controlled
fine motor skills required to write. The generic term apraxia refers to a wide
variety of motor skill deficits in which the voluntary execution of a skilled
motor movement is impaired. Apraxia can involve a single controlled movement,
or a sequence of movements, such as writing a single letter or entire words.
