Brief summary
Developmental dyslexia is a frequent learning disability. The aim of this study is to analyze cortical thickness and phonological treatment in right handed adults with developmental dyslexia. They are compared to control adults paired with age and laterality. To study phonological treatment, the researchers used functional magnetic resonance imaging (fMRI) with a rime judgement task and silent word generation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Cortical thickness | 2 years | The average cortical thickness maps of healthy subjects and dyslexic will be compared hemisphere by hemisphere. This will identify whether there are cortical areas including cortical thickness differed significantly between normal and dyslexic.ts of different ages |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Average cortical thickness | 2 years | For each group, cortical thickness maps of average left and right hemispheres are compared. This will identify whether there is an asymmetry left / right in terms of cortical thickness in normal subjects and dyslexic. |
