Dyslexia is a specific learning difficulty that affects the way individuals read, write, and spell. It is estimated that between 5-10% of the world’s population has dyslexia, making it the most common learning disability globally. However, the exact causes of dyslexia remain a topic of debate within the scientific community. Some argue that dyslexia is a condition individuals are born with, while others believe it can emerge as a result of environmental factors. Let’s explore this question further and examine the evidence on whether dyslexia is born or made.

The Genetic Perspective
Many researchers believe that genetics play a significant role in the development of dyslexia. They argue that individuals may be born with a genetic predisposition to the condition, as it tends to run in families. Studies have shown that if one or both parents have dyslexia, their children are more likely to also exhibit signs of dyslexia. In fact, certain genes have been identified that appear to be associated with dyslexia, further supporting the genetic perspective.
One study conducted by the Yale School of Medicine found that individuals with dyslexia had alterations in the genes responsible for brain development and connectivity. These genetic differences may affect the structure and function of the brain, leading to difficulties in reading and language processing. Therefore, it can be argued that dyslexia is largely influenced by genetics and may be present from birth.
The Environmental Perspective
While genetics may play a role in dyslexia, environmental factors should not be disregarded. Some researchers argue that certain environmental factors can contribute to the development of dyslexia, even in individuals without a genetic predisposition. These factors can include educational experiences, exposure to language, and early childhood development.
A study published in the Journal of Abnormal Psychology found that children from lower-income backgrounds were more likely to experience reading difficulties compared to their peers from higher-income backgrounds. This suggests that socioeconomic factors can impact the development of dyslexia. Additionally, inadequate educational resources, such as a lack of specialized instruction for dyslexic students, can contribute to reading difficulties and potentially exacerbate dyslexic symptoms.
The Interaction Perspective
Another perspective suggests that dyslexia arises from the interaction between genetic and environmental factors. This viewpoint recognizes that both nature and nurture play important roles in the development of dyslexia. It suggests that individuals may be born with a genetic predisposition to dyslexia, but environmental factors can either trigger or inhibit its manifestation.
For example, a child with a genetic predisposition towards dyslexia may struggle more with reading and writing if they are not exposed to early literacy activities or if they do not receive appropriate educational support. On the other hand, a child with the same genetic predisposition, but who receives early intervention and su
