Deep dyslexia
Deep Dyslexia
Deep dyslexia (/di:p dɪsˈlɛksɪə/) is a form of dyslexia that disrupts reading processes. It is a type of acquired dyslexia, meaning it typically occurs after a person has already learned to read.
Etymology
The term "deep dyslexia" was first used in the 1970s. It comes from the Greek words "dys" meaning difficult, and "lexis" meaning word.
Definition
Deep dyslexia is characterized by the inability to read non-words and the production of semantic errors. For example, a person with deep dyslexia may read the word "ship" as "boat". This is different from surface dyslexia, where individuals struggle with irregularly spelled words but can read non-words.
Symptoms
Symptoms of deep dyslexia include:
- Difficulty reading unfamiliar words and non-words
- Semantic errors in reading
- Difficulty with phonological processing
- Difficulty reading function words
Causes
Deep dyslexia is usually caused by damage to the left hemisphere of the brain, often due to stroke or brain injury. It is also associated with Broca's area, a region of the brain involved in language production.
Treatment
Treatment for deep dyslexia often involves speech therapy and cognitive rehabilitation. Strategies may include phonological awareness training, semantic feature analysis, and reading comprehension strategies.
