Level 2 autism, also known as Type 2 autism, is a neurodevelopmental disorder that affects how an individual communicates and behaves. It is one of three recognized levels of autism, with level 1 being the mildest, level 2 somewhat more severe, and level 3 the most severe level. Individuals with level 2 autism require substantial support and have problems that are more readily obvious to others. They may have challenges in verbal and nonverbal communication, as well as reduced or abnormal responses to social cues. Inflexibility of behavior is also more pronounced than in level 1 autism, and repetitive behaviors appear more frequently and may be obvious to casual observers. Children with level 2 autism may have difficulty coping with changes in routine, which can cause challenging behavior. It is important to monitor developmental milestones early on to diagnose level 2 autism, and individuals with this condition may need extra support at home or school.
