Diagnosis and Identification Interpretation

Despite often being mistaken for shyness or language issues, Selective Mutism is an anxiety disorder that demands vigilant diagnosis and early intervention to prevent the silent suffering of affected children from being overlooked.

Long-term Outcomes and Prognosis

About 15-23% of children diagnosed with Selective Mutism will spontaneously recover without intervention
The average duration of untreated Selective Mutism can be up to 4 years or longer

While a quarter of children with untreated Selective Mutism may develop social anxieties later, timely intervention remains crucial to break the silence and prevent long-term emotional shadows.
