Alexia without agraphia is a neurological disorder characterized by the selective inability or impairment to read written language or words, despite the ability to write them fluently. It is a rare condition caused by damage to the brain areas involved in reading comprehension.
Individuals affected by this condition typically experience normal language skills, including intact verbal comprehension and speaking abilities. However, they struggle specifically with reading text and recognizing written words. This means they may have difficulty comprehending sentences, paragraphs, or even basic words, resulting in impaired reading comprehension.
The distinguishing feature of alexia without agraphia is the preservation of writing skills. Unlike other forms of alexia, where both reading and writing abilities are affected, individuals with alexia without agraphia can produce written language without difficulty. They may be able to write coherent sentences and articulate their thoughts effectively using written language, despite not being able to read or understand written text.
The underlying cause of alexia without agraphia is typically damage to the dominant angular gyrus, a region located in the parietal lobe of the brain. This damage can result from strokes, head injuries, or tumors affecting the brain regions responsible for language processing.
Treatment for alexia without agraphia focuses on therapies aimed at improving reading skills. This may include strategies like word recognition exercises, working with a speech and language therapist, or utilizing assistive technologies to aid reading comprehension.
