It is estimated that about one in 20 people have some degree of difficulty with reading. Of these 20%, about 10% have a type of learning disability called dyslexia. Dyslexia is generally not hereditary and has no connection to intelligence. There are many different types of dyslexia, and some people may have difficulty with reading in more than one way.
Between 3 and 5 million people in the United States have some degree of Irlen syndrome.
About two to three in every five people who have learning disabilities are color blind. In the United States, between three and five million people have some degree of Irlen Syndrome. This is a higher percentage than the percentage of color blind individuals in the general population. These three to five million people are estimated to have difficulty reading or processing written or spoken information because of the way the information is represented in their brains.
Men and women are equally affected.
If you suspect that you have this condition, you should talk to your doctor. Currently, it is estimated that about one in every five people is born with it. However, there is no way to tell if you have it just by looking at you.
Irlen syndrome generally occurs in people who are of normal or above-average intelligence.
While there is no concrete number, an estimated 4% of the population is affected by the condition.
Irlen syndrome is not tied to a particular age group.
There is no exact number of people on the spectrum of having the condition, as it is not a disorder recognized by the U.S. Centers for Disease Control (CDC). However, estimates put the number at one in every 20 or 30 people, which is about the same percentage of the population who has color blindness.
Additional forms of learning disability are often associated with Irlen syndrome, such as dyslexia and attention deficit hyperactivity disorder.
Some estimates suggest that as many as one in five people is born with a form of dyslexia with an overlap of some symptoms with color blindness. However, it is not clear whether color blindness is genetically linked to dyslexia and whether they share the same underlying cause. If you struggle to read or have difficulty spelling, one possible reason could be a form of dyslexia called "Irlen syndrome" which is also called color-word dyslexia.
Some people who have Irlen syndrome may also have a condition known as auditory processing disorder.
Because the symptoms of Irlen Syndrome vary widely, it is difficult to determine just how many people are affected by it. One online source estimates that between one in 25 and one in 50 people suffers from the condition. This means that approximately 12-30% of the population may have some degree of difficulty with reading.
The symptoms of Irlen syndrome can affect a person’s reading ability and cause difficulties in other areas of school such as writing, spelling, and math.
The percentage of the population that has the condition is estimated to be between 5 and 20 percent. This means that somewhere between 20 and 100 million people around the world may have the condition. It is estimated that between 15 and 30 percent of those who have it are severely affected.
Conclusion
About 1 in 20 people have the condition. While the number of people affected varies, it’s estimated that about one in 20 people have some form of learning difficulty caused by the condition. Researchers believe there are about two to three times as many people with Irlen Syndrome today as there were 30 years ago.
