What this research studies

You would be part of a clinical program for people with Down Syndrome Regression Disorder (DSRD) where doctors collect medical histories, symptom measures, and laboratory tests. Participants may receive one of three therapeutic approaches used for DSRD (for example, benzodiazepines like lorazepam, electroconvulsive therapy, or immune-targeted therapy such as IVIG) and will be followed for response and safety. The team will also study blood and other markers to see if immune system changes are linked to regression and treatment response. Results aim to show which patients benefit from which approaches and why.

Who could benefit from this research

Good fit: People with Down syndrome who have new, measurable regression such as loss of daily living abilities, mutism or catatonia, hallucinations, delusions, or increased aggression would be the intended participants.

Not a fit: People with Down syndrome who do not have new-onset regression, whose symptoms reflect stable lifelong disability, or who cannot safely receive the specific treatments may not benefit from this project.

Why it matters

Potential benefit: If successful, this work could identify treatments and biological markers that help people with DSRD recover skills and reduce harmful symptoms.

How similar studies have performed: Previous case reports and small series suggest benzodiazepines, ECT, and immune therapies can help some individuals, but these approaches have not been compared in a systematic clinical program.
