Dyslexia
From Wikipedia, the free encyclopedia
Dyslexia, also known as reading disorder, is a neurodevelopmental condition in which people have difficulty reading despite normal intelligence. Different people are affected to different degrees.
Problems may include difficulties in spelling words, reading quickly, writing words, sounding out words in the head, pronouncing words when reading aloud, and understanding what one reads. Often these difficulties are first noticed at school.
The cause of dyslexia is believed to involve both genetic and environmental factors. Some cases run in families. Dyslexia that develops due to a traumatic brain injury, stroke, or dementia is sometimes called acquired dyslexia.
Treatment involves adjusting teaching methods to meet the person's needs. While not curing the underlying problem, it may decrease the degree or impact of symptoms. Treatments targeting vision are not effective.
