Study genes in autism and related conditions using blood samples
This study looks for genetic reasons for autism by collecting blood samples from people with autism, people without autism, and their relatives. The results may help researchers better understand causes and risk factors, even if you only participate through testing a sample.
Grenoble, GrenobleAges 2–70 - NCT04798274Recruiting
Brain wiring study in autism using safe hearing tasks
This study looks at how a brain chemical related to calming signals (“GABA”) may affect how people process sounds in autism. The goal is to understand brain function during hearing tasks, which could help guide future treatments.
Bethesda, MarylandAges 11–25 - NCT04899544Recruiting
Center vs home therapy for autism with PRT coaching
This study compares two ways of delivering Pivotal Response Treatment (PRT) for young children with autism—at a center or in the home. It may help your child by testing which approach better supports language and autism-related communication skills.
Stanford, CaliforniaAges 2–5 - NCT04923854Recruiting
Study of autism using child data you provide
This study looks at children with autism to understand patterns over time, using information from past and future records. Your involvement could help researchers learn how different needs may show up and change.
ParisAges 1–18 - NCT04936009Recruiting
Brain stimulation study for adults with autism
This study tests whether transcranial magnetic stimulation (a non-surgical brain stimulation) can affect brain activity and learning in adults, including some autistic adults. You may also do EEG and eye-tracking tasks during the study.
New Haven, ConnecticutAges 18–40 - NCT04972136Recruiting
Brain stimulation treatment for depression in young adults with autism
This trial studies a noninvasive brain stimulation (rTMS) to help reduce depression symptoms in young adults who have autism. It aims to find out if this treatment can improve mood and daily functioning without requiring recent changes to medications.
Toronto, OntarioAges 16–35 - NCT05035511Recruiting
Predicting tDCS results in autistic teens with machine learning
This study uses machine learning to predict how well a teen with autism may respond to tDCS, a non-invasive brain stimulation. It mainly looks at personal factors (like understanding instructions and baseline abilities) to better estimate treatment outcomes.
