Meguid bu ụzọ chọpụta mmụba nke mgbanwe X na-adịghị ike n'etiti ụmụ nwoke Ijipt. Mgbanwe ahụ mere 0.9 n'ime 1000 ụmụ nwoke Ijipt.

Meguid nyochara ọdịdị ụbụrụ na ma ọrịa x na-adịghị ike na ndị ọrịa autistic na ndị ọrịa Autism ma kpebie ma ọ bụrụ na enwere ọdịiche ọ bụla dị ịrịba ama na nsogbu mkpụrụ ndụ ihe nketa. E ji 1.5-T magnetic resonance imaging (MRI) mee ihe. Enweghị ọdịiche dị ịrịba ama na ọdịdị ụbụrụ gụnyere "ọnụ ọgụgụ ụbụrụ zuru oke, ọnụ ọgụgụ mpaghara, akara gyrification, omimi sulcal, na ọkpụrụkpụ ụbụrụ". Ndị ọrịa Autistic nwere mbelata na medial prefrontal bilaterally na hapụrụ anterior cingulate cortices nke ụbụrụ. A chọpụtara na medial prefrontal na anterior cingulate dị ịrịba ama na nghọta mmekọrịta mmadụ na ibe ya na ndị ọrịa autistic na ndị na-adịghị ike X nwere nkwarụ na ha abụọ.
