Học thuậtThân thiện
Definition
Noun: A medical condition characterized by the loss of the ability to read or comprehend written language, despite having normal vision and intelligence, and typically without the loss of the ability to write. It is often caused by brain injury, such as a stroke, affecting specific areas of the brain involved in language processing.
Usage
Alexia is a specific neurological disorder. It is used in medical, psychological, and linguistic contexts. - The patient developed alexia following a cerebral hemorrhage in the left hemisphere. - Alexia without agraphia (the inability to write) is a distinct clinical syndrome. - Research into alexia helps scientists understand how the brain processes written words.
Advanced Usage
- Pure alexia: Also known as "word-form dyslexia" or "alexia without agraphia," this is a specific type where the patient cannot read words but can often still write and recognize letters individually.
- Central alexia: Refers to types of alexia (like phonological or deep alexia) that involve broader language processing deficits and are often accompanied by other language impairments such as aphasia.
