Consequently, treatment at an early age is important. If not addressed, selective mutism tends to be self-reinforcing. Others may eventually expect an afflicted child to not speak and therefore stop attempting to initiate verbal contact. Alternatively, they may pressure the child to talk, increasing their anxiety levels in situations where speech is expected. Due to these problems, a change of environment may be a viable consideration. However, changing school is worth considering only if the alternative environment is highly supportive, otherwise a whole new environment could also be a social shock for the individual or deprive them of any friends or support they have currently. Regardless of the cause, increasing awareness and ensuring an accommodating, supportive environment are the first steps towards effective treatment. Most often afflicted children do not have to change schools or classes and have no difficulty keeping up except on the communication and social front. Treatment in teenage or adult years can be more difficult because the afflicted individual has become accustomed to being mute.
