Autism should not be seen as single condition with one cause, say scientists

The study suggests that autism should not be considered a single condition with a single underlying cause. Researchers found that individuals diagnosed with autism in early childhood, typically before the age of six, often have a distinct genetic profile compared to those diagnosed later. The study, which analyzed genetic data from over 45,000 autistic people in Europe and the US, showed that those diagnosed in early childhood were more likely to exhibit behavioral difficulties from an early age, including challenges with social interaction. However, their condition remained relatively stable over time. These findings challenge the traditional view of autism as a uniform disorder and highlight the need for a more nuanced understanding of the condition's diverse manifestations and underlying mechanisms. The study emphasizes the importance of recognizing the heterogeneity within the autism spectrum and tailoring interventions and support accordingly.
