This condition and autism are separate disorders, each with its own symptoms and diagnostic criteria. While both can impact communication, they do so in different ways. This condition is characterized by a consistent inability to speak in certain social situations where speaking is expected, despite the ability to speak in other cases. It is often associated with extreme shyness or social anxiety. Autism, on the other hand, is a developmental disorder characterized by difficulties with social interaction and communication and restricted and repetitive behaviour. Individuals with autism may also have unique strengths and differences. While an individual can have both conditions, having one does not imply the presence of the other. Each condition requires its treatment approach, so accurate diagnosis is crucial.
