Unraveling the Genetic Tapestry

In 99% of cases, dyslexia is something that people are born with, inheriting specific genetic variations from one or both of their parents, much like the color of their hair and other genetic traits. However, in rare instances, external factors such as strokes, brain injuries, or surgeries can induce dyslexia-like symptoms.


The majority of dyslexic individuals have a genetic predisposition to the condition. Specific variations in genes related to brain development and language processing contribute to the atypical wiring of neural circuits associated with reading and language skills. These genetic factors are inherited, influencing the way the brain functions from an early age.


Contrary to viewing dyslexia solely as a deficit, it's essential to recognize the strengths associated with this neurodiversity. Dyslexic individuals often excel in areas such as visual thinking, spatial awareness, and 3D reasoning.

These strengths are not present in individuals who acquire dyslexia due to brain injuries or surgeries, highlighting the distinctive nature of genetically inherited dyslexia.


In very uncommon cases, dyslexia-like symptoms can emerge as a result of external factors affecting the brain. Strokes, traumatic brain injuries, or surgeries near the left ear, where the brain's reading centers are located, may disrupt the typical functioning of these regions. This disruption can lead to difficulties in reading, spelling, and writing, resembling dyslexic symptoms.


While the outcome may appear similar, there are crucial distinctions between dyslexia inherited through genetics and dyslexia acquired through brain injuries. Genetically inherited dyslexia is part of a complex interplay of neural networks, influencing various aspects of cognitive processing. In contrast, acquired dyslexia results from the loss of specific brain functions due to trauma or surgery.


Neurodiversity encompasses the idea that neurological differences, whether genetically inherited, contribute to the rich tapestry of human cognition. Dyslexia serves as an example of how diverse cognitive profiles can coexist within the population. Understanding and appreciating these differences can lead to more inclusive approaches in education and society.


Dyslexia, in most cases, is a neurodevelopmental condition influenced by genetics, shaping the cognitive landscape of individuals from an early age. However, rare instances of acquired dyslexia shed light on the complexity of the human brain and the potential impact of external factors on cognitive functions.

Embracing neurodiversity and recognizing the strengths associated with dyslexia contribute to a more inclusive understanding of human cognition and the varied ways in which our brains function.
