Diagnosis, treatment, and experiences of autism varies globally. Although the diagnosis of autism is rising in post-industrial nations, diagnosis rates are much lower in developing nations. Africa Diagnosis Autism research conducted in Africa has been infrequent and unrepresentative of all African countries, making the prevalence of autism in Africa difficult to estimate. Prevalence may be underestimated because reported cases are skewed toward more severe, and thus more recognizable, cases of autism. In Africa, an autism diagnosis often co-occurs with epilepsy or intellectual disability. Treatment Possible reasons for the fact that many reported cases of autism in Africa are nonverbal cases include difficulty finding services even when a diagnosis is given. Educational and behavioral interventions for children with autism are largely unavailable, mental health care facilities are few, and there are too few facilities and personnel trained to work with autistic children in reference to the estimated number of autism cases in Africa. Bakare and Munir found that health care workers had low to average knowledge and awareness of autism spectrum disorder. In particular, psychiatric health care workers recognized symptoms of ASD better than pediatric health care workers, which implies that early recognition and intervention for children with autism in Africa is infrequent. Supernatural explanations of autism can influence treatment seeking by encouraging people to first seek help from spiritualists and traditional healers. Experience Studies have not elucidated the clinical presentation of autism in African nations. Autism awareness is low, particularly in sub-Saharan Africa. Bakare and Munir suggest that education for the public and for health care workers is crucial for early diagnosis of ASD so that early intervention can be effective for African children. Asia Diagnosis Autism was not recognized until the 1980s in China. The estimated prevalence of autism is 11.8 per 10,000 people while the estimated prevalence of autism spectrum conditions is 26.6 per 10,000 people. In Japan, recent estimates of autism spectrum are as high as 13 per 10,000 people. This suggests that autism is more common in Asia than previously thought. The Childhood Autism Rating Scale (CARS), Clancy Autism Behavior Scale (CABS), Autism Behavior Checklist (ABC), and Checklist for Autism in Toddlers (CHAT) are frequently used as diagnostic instruments in China. (see Autism in China) Treatment In 2013, eight South Asian countries adopted a charter at the South Asian Autism Network's first meeting. The nations plan on working with each other's ministries, and SAAN is advocating
