Introduction
The causes of autism in children may include genetic factors, abnormal prenatal environment, neurological developmental disorders, sensory integration dysfunction, and co-occurring intellectual disabilities. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve symptoms through interventions such as behavioral therapy and medication under medical guidance. Daily routines should be established for the child, and social cognition should be fostered using concrete methods such as picture books and animations.
In general, the causes of autism in children may involve genetic factors, abnormal prenatal environment, neurological development disorders, sensory integration dysfunction, and co-occurring intellectual disabilities. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve symptoms through interventions such as behavioral therapy and medication under medical guidance. Specific analyses are as follows:
1. Genetic Influence: Children with a family history of autism or neurodevelopmental disorders have an increased risk of developing the condition. Genetic susceptibility is a significant contributing factor. Early intervention with Applied Behavior Analysis (ABA) training is recommended, gradually building fundamental skills such as language and social interaction, with active parental involvement to enhance training effectiveness.
2. Abnormal Prenatal Environment: Maternal infections (e.g., rubella), exposure to chemicals, or oxygen deprivation during pregnancy may impair fetal brain development. Regular prenatal check-ups are essential to identify potential risks. After birth, early developmental screening should be conducted, and any abnormalities should be addressed promptly. Sensory integration games can help promote proper brain function.
3. Neurological Development Disorders: Imbalances in brain neurotransmitters or abnormal neuronal connections can impair abilities in social communication and interaction. Under medical supervision, medications such as risperidone oral solution, aripiprazole tablets, and methylphenidate hydrochloride sustained-release tablets may be prescribed, along with specialized training from speech therapists.
4. Sensory Integration Dysfunction: Over-sensitivity or under-responsiveness to stimuli such as sound, light, and touch can lead to behavioral issues and exacerbate autistic symptoms. Sensory integration equipment—such as balance beams and tactile balls—can help improve sensory processing. Avoid sudden, intense stimuli in daily life and maintain a calm, supportive environment.
5. Co-occurring Intellectual Disability: Some children with autism also experience delayed intellectual development, further affecting their adaptive functioning. As directed by a physician, medications such as piracetam tablets, oxiracetam capsules, and citicoline sodium tablets may be used, combined with cognitive training to improve self-care and learning abilities.
Establishing a consistent daily routine is important. Use concrete teaching tools such as picture books and animated videos to guide the child’s social understanding. Parents should remain patient, join autism support groups, and leverage professional resources and community support to foster their child's development.
