What Causes Dyslexia?

Story Updated: Jun 10, 2013

Is dyslexia caused by a visual processing dysfunction? That's been the question for decades.

Dyslexia is a common learning difference that impacts up to 12-percent of the population. It makes it difficult to read.

Now, with the help of high tech imaging...a team at Georgetown University Medical Center is looking to provide some answers about the role visual symptoms play in the disorder.

The researchers conducted a series of experiments using functional MRI. They compared brain activity in dyslexic kids versus regular readers in the same age group in different age groups and after reading intervention.

The results showed that while there was a strong correlation between reading ability and brain activity in the visual centers, treating vision deficits did not result in better reading. In fact, the researchers say it was the other way around intensive tutoring in reading led to improved visual activity.

Bottom line, vision issues don't cause dyslexia...but instead, may be a consequence of dyslexic kids reading less.

The researchers say their findings have important implications for the treatment of dyslexia, which should revolve around the skill of reading.

The LOURDES Regional Cancer Center is the area's premier facility dedicated to spiritually based, comprehensive cancer care. Since 1957, the Lourdes Regional Cancer Center has been providing the Southern Tier of New York with outstanding cancer care.

Now, nearly fifty years later, the LOURDES Regional Cancer Center continues that mission. Since 1971, the Lourdes Regional Cancer Center has been accredited as a Community Hospital Comprehensive Cancer Program. Most recently, Lourdes has been awarded the 2008 Commission on Cancer Outstanding Achievement Award by the Commission on Cancer American College of Surgeons. The Award is designed to recognize cancer programs that strive for excellence in providing quality care to cancer patients. Lourdes is one of only 95 facilities in the US to receive this award.

Today, Lourdes is among the largest and most sophisticated community cancer centers in the country. Here within the region's premier facility dedicated to the fight against cancer we've gathered the area's top physicians and oncologists. We've assembled select teams of cancer nurses and specialists and we've brought to the Southern Tier some of the newest weapons to fight cancer.

Pastoral care, nutrition services, and rehabilitation services are also available for both outpatients and inpatients. Lourdes Regional Cancer Center also maintains a link with the National Cancer Institute's (NCI) database. This database provides the latest information on research advances and new treatments, as well as emerging topics on the influence of genetics, environmental factors and lifestyle factors in the development of cancer.
