Agraphia is a neurological condition that affects a person's ability to write. It can occur after brain injuries, strokes, or diseases that impact the areas of the brain responsible for language and motor skills. Individuals with agraphia may struggle to form letters, spell words, or organize their thoughts on paper. There are different types of agraphia, each linked to specific brain functions. For example, phonological agraphia affects the ability to write words phonetically, while graphemic agraphia involves difficulty in writing due to problems with letter formation. Treatment often includes therapy to improve writing skills and address underlying causes.
