Introduction
In general, autism in adults may be caused by genetic factors, abnormal neural development, comorbid anxiety disorders, comorbid depression, or schizophrenia spectrum disorders. It is recommended to seek medical attention promptly, identify the underlying cause, and undergo symptomatic treatment under a doctor's guidance. In daily life, creating an inclusive and understanding environment is important, and excessive pressure for social interaction should be avoided.
In general, adult autism may be caused by factors such as genetic influences, abnormal neural development, comorbid anxiety disorders, comorbid depression, or schizophrenia spectrum disorders. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analysis is as follows:
1. Genetic influences: Autism has a clear hereditary tendency. Individuals with a family history may continue to experience symptoms into adulthood or develop noticeable manifestations later in life. It is advisable to actively learn about autism, understand one's own characteristics, and, with professional guidance, develop suitable social and daily living strategies.
2. Abnormal neural development: Abnormal development of brain neural circuits during childhood can lead to persistent difficulties in social communication and interaction in adulthood. Participating in targeted rehabilitation programs—such as social skills group activities—can gradually improve interpersonal abilities.
3. Comorbid anxiety disorder: Individuals with autism are prone to anxiety due to social challenges, manifesting as social avoidance and emotional tension. Patients may take medications such as buspirone hydrochloride tablets, tandospirone citrate capsules, or lorazepam tablets as prescribed, along with social support therapy.
4. Comorbid depression: Prolonged social isolation can lead to low mood, exacerbating autism-related symptoms and creating a vicious cycle. Antidepressants such as sertraline hydrochloride tablets, fluoxetine hydrochloride capsules, or fluvoxamine maleate tablets should be taken as directed by a physician, combined with psychological counseling.
5. Schizophrenia spectrum disorders: Some individuals with autism may have co-occurring spectrum disorders, presenting symptoms such as perceptual abnormalities and disorganized thinking. Medications such as risperidone tablets, olanzapine tablets, or quetiapine fumarate tablets may be used under medical supervision; severe cases may require hospitalization for systematic intervention and treatment.
In daily life, it is important to create an inclusive and understanding environment and avoid forcing social interactions. Developing consistent hobbies and interests can help build self-confidence in areas of strength. Family members and friends should offer full support to assist the individual in gradually adapting to the rhythms of social life.
