How can these symptoms be distinguished from typical adult behaviors?
As with children, the key distinction lies in the persistence and intensity of these behaviors. If these symptoms are causing significant impairment in daily life and are not consistent with the individual's cultural norms or personal preferences, it may indicate autism. Additionally, professionals consider the overall developmental trajectory of the adult – if the person is regressing or not making expected progress in other areas of development, this may indicate autism.
