Autism
en.wikipedia.org/wiki/Autism
Autism is a developmental disorder characterized by difficulties with social interaction and communication, and by restricted and repetitive behavior.[3] Parents often notice signs during the first three years of their child's life.[1][3] These signs often develop gradually, though some autistic children experience worsening in their communication and social skills after reaching developmental milestones at a normal pace.[14]
Autism is associated with a combination of genetic and environmental factors.[4] Risk factors during pregnancy include certain infections, such as rubella, toxins including valproic acid, alcohol, cocaine, pesticides, lead, and air pollution, fetal growth restriction, and autoimmune diseases.[15][16][17] Controversies surround other proposed environmental causes; for example, the vaccine hypothesis, which has been disproven.[18][19] Autism affects information processing in the brain and how nerve cells and their synapses connect and organize; how this occurs is not well understood.[20] The Diagnostic and Statistical Manual of Mental Disorders (DSM-5), combines forms of the condition, including Asperger syndrome and pervasive developmental disorder not otherwise specified (PDD-NOS) into the diagnosis of autism spectrum disorder (ASD).[3][21]
Early behavioral interventions or speech therapy can help autistic children gain self-care, social, and communication skills.[better source needed][6][7] Although there is no known cure,[better source needed][6] there have been cases of children who have achieved good outcomes.[better source needed][22] Some autistic adults are unable to live independently.[12] An autistic culture has developed, with some individuals seeking a cure and others believing autism should be accepted as a difference to be accommodated instead of cured.[23]
Globally, autism is estimated to affect 24.8 million people as of 2015.[13] In the 2000s, the number of people with autism worldwide was estimated at 1–2 per 1,000 people.[24] In the developed countries, about 1.5% of children are diagnosed with ASD as of 2017,[25] from 0.7% in 2000 in the United States.[26] It occurs four-to-five times more often in males than females.[26] The number of people diagnosed has increased dramatically since the 1960s, which may be partly due to changes in diagnostic practice.[24] The question of whether actual rates have increased is unresolved.[better source needed][24]
