Among the 18 studies in Dyslexia with a site in Italy, from their registry updates:
Developmental dyslexia (DD) is a multifactorial disorder that hampers the education of about 10% of individuals across cultures and is associated to both phonological and visual deficits. The latter have been linked to a deficit in the magnocellular-dorsal (M-D) visual stream, that has a critical role in guiding the activity of ventral visual stream areas where letters identity is extracted. Here, we will test the efficacy of transcranial alternate current stimulation (tACS) of the M-D stream combined with reading trainings in adult participants with DD, assessing the neurophysiological underpinnings of these new trainings with EEG and fMRI/DTI.

Ran from Dec 2021 to primary completion in Dec 2024, 36 months.
Of 62 non-industry interventional studies with no phase under Dyslexia, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 57. This study's 36 months is above that.
Counting every sponsor, half of 69 studies reached it within 24 months; a quarter within 9 and three quarters within 57.
