Autism spectrum disorder (ASD) is a neurodevelopmental condition affecting social interaction, communication, and behavior, often identified in early childhood with diverse genetic and environmental factors.
The following are Autism Speaks’ “Top Ten” 2014 stories in autism research based on readership and social media shares.
1. New Meta-analysis Affirms No Association Between Vaccines and Autism
A meta-analysis of ten studies involving more than 1.2 million children affirmed that vaccines don’t cause autism. The analysis found that immunization with the measles-mumps-rubella (MMR) vaccine was associated with a slight decrease in risk.

2. Physical Evidence that Autism Starts During Prenatal Development
Researchers found a common pattern of disruption in the prenatal brain development of children who had autism. Their study, supported in part by Autism Speaks, analyzed the donated post-mortem brain tissue of 11 children with autism and of 11 unaffected children. In 10 out of the 11 ASD cases, they found recurring patches of abnormal development in layers of the cerebral cortex that form during prenatal development. By contrast, they found these patches in just 1 of the 11 children unaffected by autism. The researchers propose that early intervention may help the brain “rewire” around these disturbed areas.
3. MSSNG: Changing the Future of Autism with Open Science
This historic collaboration between Autism Speaks and Google is queueing up 10,000 anonymous autism genomes and making the data freely available for research anywhere, anytime. “We don’t know enough about autism. MSSNG is the search for the missing answers.”

4. Broccoli-Sprout Extract Shows Promise for Easing Autism Symptoms
In a small placebo-controlled trial, sulforaphane supplements eased autism symptoms in nearly half of 29 participants affected by autism. Experts called the results “promising” but cautioned that larger studies were needed to determine effectiveness and safety.
5. Studies Implicate Early Injury to Cerebellum as Major Cause of Autism
In a review of published studies, Princeton researchers said they found strong evidence that injury to the cerebellum during pregnancy or birth may be the leading nongenetic cause of autism. A small but crucial brain region, the cerebellum sits near the base of the skull and is best known for coordinating movement. During brain development, it plays a crucial role in directing cross wiring to other brain regions.
6. Brain Study Suggests that Autism Involves Too Many Synapses
Researchers analyzing donated postmortem tissue from children affected by autism found that their brains had a significant surplus of connections between brain cells. These excess synapses appeared to result from a slowdown in the normal pruning process that occurs during brain development. The investigators then used a mouse model of autism to show that they could restore normal synaptic pruning and reduce autism-like behaviors with an experimental medication. They called for further research that might advance to a clinical trial involving people with autism.
7. Study Links Specific Gene to Autism Subtype
Researchers linked a specific gene mutation to a newly identified subtype of autism. Experts hailed the finding as a crucial step toward using genomic testing to develop individualized treatments for autism spectrum disorder.

8. Autism’s Subtle Early Signs: More Findings from Infant Eye Tracking
Another Autism Speaks “Baby Sibs” study found that even earlier differences in social attention – this time at 6 months – flag high risk for autism. The researchers called for the development and testing of very early interventions that engage at-risk babies in enjoyable activities that involve shared attention.
9. Autism ‘Baby Sibs’ Study Identifies Another Early Red Flag
Researchers with the Autism Speaks Baby Sibling Research Consortium used eye-tracking technology to discover that babies who begin showing decreased interest in facial expressions at 8 months go on to develop more-severe autism symptoms by age 3. The authors expressed hope that this early red flag signaled an important window of opportunity for early intervention that improves outcomes.
10. Autism and GI Disorders: Largest-Ever Analysis Confirms Strong Link
The first meta-analysis of all peer-reviewed research on autism and gastrointestinal conditions showed that children with autism have four times the rate of GI problems as do other children. At the forefront of this research, Autism Speaks launched an unprecedented initiative funding major investigations into autism’s gut-brain connect.

From Autism Research to Meaningful Support
The research highlighted in this article reflects how understanding of autism has continued to develop, from genetics and early brain development to early signs, communication, behavior, and co-occurring health concerns. While research can help improve our understanding of autism, individualized support remains an important part of helping children and adults navigate everyday life.
At New Horizons Wellness Services, our team offers services that may support individuals with autism and their families based on their individual needs and goals:
● Occupational Therapy Services: Occupational therapy can help children and adults build practical skills for daily living, school, work, and community participation. Pediatric occupational therapy may address sensory processing, fine and gross motor skills, self-care, routines, and other functional challenges that can affect children with autism. Occupational therapy for adults can similarly support independence and participation in everyday activities.
● Social Skills Groups: Social interaction and communication are important areas of support for many individuals with autism. Social skills groups provide opportunities to practice communication, cooperation, emotional awareness, conversation, and appropriate interactions with peers in a structured and supportive environment.
● Counseling Services: Counseling can provide emotional and behavioral support for individuals and families navigating challenges associated with autism. Depending on individual needs, counseling may help with anxiety, emotional regulation, coping strategies, relationships, or adjusting to changes and everyday challenges.
Autism research continues to expand our understanding of the condition, but every individual with autism has their own strengths, needs, and experiences. Combining current knowledge with individualized, supportive services can help children and adults develop skills, increase participation in daily life, and work toward meaningful personal goals.

Frequently Asked Questions
Are vaccines linked to autism?
Extensive research, including large meta-analyses, has shown that vaccines do not cause autism. Scientific evidence continues to support vaccination as safe while dispelling myths about autism causation.
Can early brain development affect autism risk?
Yes. Studies indicate that autism can start during prenatal brain development. Early identification and interventions can help support brain growth and functional development.
What role do genetics play in autism?
Genetic factors, including specific gene mutations, are associated with certain autism subtypes. Understanding genetics helps researchers develop personalized interventions and treatments for individuals with autism.
Are there early signs of autism I should look for in infants?
Yes. Research shows subtle early indicators such as decreased eye contact, social attention differences, and responsiveness to facial expressions may appear as early as 6–8 months. Awareness of these signs can guide early evaluation and intervention.
Is there a connection between autism and other health conditions?
Studies have confirmed links between autism and gastrointestinal (GI) disorders. Children with autism are more likely to experience GI challenges, highlighting the importance of comprehensive care that addresses both neurological and physical health.
