Understanding Dyslexia: The Brain, Cells, and Promising Treatments

Understanding Dyslexia: The Brain, Cells, and Promising Treatments

Dyslexia is a learning disorder that affects the ability to read, write, and spell accurately. It is estimated that around 10% of the world's population experiences some level of dyslexia, making it one of the most common learning disabilities. While the exact cause of dyslexia remains a topic of ongoing research, recent studies have shed light on the brain regions involved, cellular changes that occur, and potential treatments. This blog post aims to provide an overview of dyslexia, focusing on the brain regions implicated (T7, P7, O1, and O2), cell-level changes such as oxidative stress, and the potential benefits of neurofeedback, DHA/EPA, and antioxidants in managing dyslexia.

Understanding Dyslexia at the Brain Level

Neuroimaging studies have revealed that dyslexia is associated with specific brain regions. One commonly implicated area is the left posterior temporal region, particularly the T7 and P7 areas. These regions are involved in phonological processing, which is crucial for decoding and understanding written language. Additionally, the O1 and O2 areas, responsible for visual processing, are also found to be affected in individuals with dyslexia.

Cell-Level Changes and Oxidative Stress

In recent years, researchers have started exploring the cellular changes that occur in the brains of individuals with dyslexia. One area of interest is oxidative stress, which refers to an imbalance between the production of reactive oxygen species (ROS) and the body's antioxidant defense system. Oxidative stress can lead to damage in cells and affect their functioning. Studies have suggested that oxidative stress markers are elevated in individuals with dyslexia, indicating a potential link between oxidative stress and the development of the disorder.


Harnessing Brain Plasticity for Dyslexia: Neurofeedback is a non-invasive technique that aims to train individuals to self-regulate their brain activity. It involves monitoring brainwaves, providing real-time feedback, and teaching individuals to modify their brain patterns to achieve more optimal functioning. Neurofeedback has shown promise as a potential treatment for dyslexia. By targeting the brain regions involved in reading and language processing, such as T7, P7, O1, and O2, neurofeedback can help individuals with dyslexia enhance their neural connectivity and improve their reading abilities.

The Role of DHA, EPA, and Antioxidants: Dietary interventions have gained attention as potential adjunct therapies for dyslexia. Omega-3 fatty acids, specifically docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), have been shown to support brain health and cognitive function. These essential fatty acids are abundant in fatty fish, flaxseeds, and walnuts. Including DHA and EPA in the diet of individuals with dyslexia may help support optimal brain function and potentially alleviate symptoms. Furthermore, antioxidants, such as vitamins C and E, play a crucial role in reducing oxidative stress and protecting cells from damage. Consuming a diet rich in fruits, vegetables, and other antioxidant-rich foods can support the body's natural defense mechanisms against oxidative stress. However, it is important to note that dietary interventions should be part of a comprehensive treatment plan and should be discussed with a healthcare professional.


Dyslexia is a complex learning disorder with neurological and cellular components. While dyslexia presents challenges, understanding the brain regions involved, cell-level changes like oxidative stress, and exploring potential treatments offers hope for individuals with dyslexia and their families. Neurofeedback, in combination with dietary interventions like DHA, EPA, and antioxidants, shows promise in improving reading abilities and managing dyslexia.
