In which aspects does long-term autism manifest?

The manifestations of long-term autism are mainly reflected in the following aspects: 1. Social impairments: Individuals with autism consistently experience difficulties in social interaction, struggle to establish normal interpersonal relationships, lack eye contact and emotional responsiveness, and show little interest in group activities. 2. Communication difficulties: Patients may exhibit symptoms such as mutism, speaking in a very soft voice, delayed or regressive language development, or even using gestures instead of verbal communication. 3. Restricted interests and repetitive behaviors: Patients may display excessive focus on specific objects or activities while showing little interest in others. They may also engage in repetitive, stereotyped behaviors and postures, such as repeatedly performing certain actions or insisting on rigid daily routines. 4. Other symptoms: Long-term autism may also be accompanied by intellectual and cognitive deficits, sensory abnormalities, and self-injurious behaviors.
