The DSM-V divides the symptoms of ASD into two general domains:
1. Social communication and interaction impairments: This domain includes symptoms such as difficulty in social-emotional reciprocity, deficits in nonverbal communicative behaviors used for social interaction, and challenges in developing and maintaining relationships.
2. Restricted, repetitive patterns of behavior, interests, or activities: This domain includes symptoms such as repetitive motor movements, insistence on sameness, restricted interests, and hyper- or hypo-reactivity to sensory input.
It is important to note that the DSM-5 also includes severity levels to indicate the level of support required by an individual with ASD, ranging from level 1 (requiring support) to level 3 (requiring very substantial support).
