New Brain Stimulation Treatment Shows Promise for Children with Autism
A groundbreaking brain stimulation treatment has emerged as a potential tool to enhance social skills in children with autism, according to recent research. This innovative therapy, which uses magnetic pulses to stimulate the brain, has shown promising results in improving social communication and language abilities after just five days of treatment.
The study, conducted by researchers in China, focused on a non-invasive method known as accelerated continuous theta burst stimulation (a-cTBS). This technique targets the left primary motor cortex, an area of the brain associated with movement, language, and aspects of social thinking. The findings were published in The BMJ, highlighting the potential of this approach as a complementary treatment for children with autism.
Autism spectrum disorder affects how individuals communicate, interact, and experience the world. It is estimated that one in 31 children in the United States and one in 45 adults are affected by autism. Many autistic children face challenges in social communication, such as interpreting facial expressions, taking turns in conversations, understanding social cues, and relating to peers.
Researchers involved in the trial emphasized that these difficulties are considered core symptoms of autism, with limited treatment options available. The new therapy aims to address these challenges by targeting specific areas of the brain associated with social interaction and language development.
The study included 200 autistic children aged between four and 10 years old, who were treated at three hospitals in China. Half of the participants also had intellectual disabilities. The children were divided into two groups: one received the actual treatment, while the other underwent a sham version designed to mimic the real procedure.
Those in the treatment group experienced 10 short sessions per day for five days. Of the 200 children who started the trial, 193 completed it. Researchers evaluated changes in behavior using a standardized questionnaire that measures social responsiveness, as well as language skills.
Compared to the sham group, children who received the real treatment showed greater improvements in social communication immediately after the treatment and one month later. They also demonstrated stronger gains in language ability. However, side effects were more common in the treatment group, affecting over half of the participants compared to around three in 10 in the sham group.
The most frequently reported side effects were restlessness and discomfort on the scalp where the device was applied. Researchers noted that all side effects were mild to moderate and resolved on their own.
The team behind the study believes that the treatment could become a “feasible, effective, and scalable therapeutic option” for children with autism. However, independent experts have expressed caution about the findings.
Professor Dorothy Bishop, an expert in developmental neuropsychology at the University of Oxford, raised concerns about the demanding schedule of the treatment for young children, especially those with autism who may struggle with disrupted routines. She also questioned whether lasting changes in social behavior could realistically occur so quickly.
Dr David McGonigle from Cardiff University highlighted that while the improvements were statistically significant, they were modest and only measured over one month. He stressed the need for further research before the treatment can be used clinically.
In a linked editorial, academics from Hong Kong expressed cautious optimism about the findings. They emphasized that brain stimulation should not replace psychosocial or educational support but could potentially become part of a broader care package for autistic children with significant social communication difficulties.
