ABSTRACT
In order to read, various brain regions must interact with each other accurately and quickly. Imaging studies play an important role in elucidating the neurobiology of dyslexia, which is defined as not being able to read accurately and fluently. Structural and functional magnetic resonance (MR) imaging are used in elucidation of basic neurobiological mechanisms. In structural imaging Voxel Based Morphometry, diffusion tensor imaging, MR spectroscopy; in functional imaging, functional magnetic resonance imaging investigations are carried out. During the paradigms used in functional MR imaging studies, although cerebral hypoactivation is seen in general, circuits including the temporobasal, parietal and frontal lobes are often disrupted in the left and right hemispheres without lateralization. The findings of structural imaging studies show that the neural mechanisms of dyslexia are highly complex and the reading function is largely related to the maturation of the brain. In this review, it is aimed to shed light on the treatment of these cases and future studies of MR studies and their results in patients with dyslexia.
