Alexia
Alexia
Alexia (/əˈlɛksiə/; from the Greek a- meaning "without", and lexis meaning "word") is a medical condition characterized by the loss of the ability to read, due to brain damage or stroke. It is also known as acquired dyslexia or word blindness.
Types of Alexia
There are several types of alexia, including:
- Pure Alexia: This is characterized by a severe reading problem, while other language skills such as writing, speaking, and understanding spoken words remain intact.
- Surface Alexia: In this type, individuals can read words phonetically but struggle with irregularly spelled words.
- Phonological Alexia: This is characterized by the inability to sound out words and read non-words.
- Deep Alexia: This is characterized by the inability to read abstract words, with the reading of concrete words relatively preserved.
Causes
Alexia is typically caused by damage to the areas of the brain that are involved in reading. This can occur due to a stroke, brain tumor, traumatic brain injury, or certain neurological conditions such as Alzheimer's disease or Multiple Sclerosis.
Treatment
Treatment for alexia typically involves speech therapy and occupational therapy, which can help improve reading skills and compensate for reading difficulties. The specific treatment approach may vary depending on the type of alexia and the individual's specific needs.
