Effects of Poly-unsaturated Fatty Acids on Developmental Dyslexia

Poly-unsaturated Fatty Acids and Developmental Dyslexia: Correlations With Cognitive Performance and Effects of Supplementation in Addition to Neuropsychological Treatment

Not applicable Interventional IRCCS Eugenio Medea · NCT04287530

This study is testing if giving children with developmental dyslexia a supplement of poly-unsaturated fatty acids can help improve their reading skills compared to a placebo and a neuropsychological intervention.

What this trial studies

This study investigates the impact of poly-unsaturated fatty acids (PUFAs) on children diagnosed with developmental dyslexia. Participants aged 7 to 15 will receive either PUFA supplementation, a neuropsychological intervention, or a placebo. The study aims to assess the role of PUFAs in neuronal development and functioning, particularly in relation to reading abilities. The research will include both dyslexic participants and a control group without reading difficulties to compare outcomes.

Who should consider this trial

Good fit: Ideal candidates are children aged 7 to 15 with a formal diagnosis of developmental dyslexia and no prior specific rehabilitation treatment.

Not a fit: Patients who do not have a diagnosis of dyslexia or have received prior treatment for the condition may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide new dietary interventions to improve reading skills in children with developmental dyslexia.

How similar studies have performed: While the role of PUFAs in cognitive function has been explored, this specific approach to treating developmental dyslexia is relatively novel and has not been extensively tested.
