Agraphia

 

a speech disorder marked by the loss of the ability to write.

Agraphia is observed, as a rule, in cases in which the occipital or sincipital region of the left hemisphere of the cerebral cortex in right-handed people is underdeveloped or damaged. People with agraphia either lose the ability to combine letters into words or else leave out or transpose separate syllables.
