ASD, or Autism Spectrum Disorder, is a developmental disorder that affects communication, social interaction, and behavior. It is a complex and heterogeneous condition, with individuals ranging from mild to severe levels of impairment. Research in ASD aims to better understand the causes and underlying mechanisms of the disorder, improve early diagnosis and intervention, and develop effective treatments and support services for individuals with ASD and their families. Studies in genetics, neuroscience, psychology, and education all play a role in advancing our knowledge and understanding of ASD.
