Summary

This study tests three medications—lorazepam, IVIG, and tofacitinib—in 66 people with Down syndrome (ages 8-30) who have developed a serious condition called Down Syndrome Regression Disorder (DSRD). DSRD causes sudden loss of skills, catatonia, and other severe symptoms. The goal is to see which treatment is safest and most effective at improving symptoms. Participants are randomly assigned to one of the three therapies.
