The study, published on the ‘Medical Express’ website, explained that modifying environmental factors can enhance social interaction and reduce anxiety levels in individuals with genetic predispositions. Researchers used a zebrafish animal model carrying a mutation in the UBE3A gene, which is linked to Angelman syndrome and autism spectrum disorders. The behavior of the fish was monitored in two different environments: the first was a white styrofoam tank representing an unfamiliar environment, and the second was a plexiglass tank simulating a more comfortable and secure environment. In contrast, their social responses significantly improved in the safer environment.
The study supported these observations with additional tests, including anxiety measurement, neurological activity analysis, and RNA sequencing to understand the influencing genetic mechanisms. The study noted that improper processing of visual stimuli increases anxiety and reduces social interaction in stressful environments, while these behaviors improve in familiar settings.
These results provide strong evidence for the potential development of environmental intervention strategies to improve the behavioral challenges associated with autism. Researchers hope these discoveries will contribute to the development of future interventions that can be applied to humans, enhancing the quality of life for individuals with autism spectrum disorder.
