2. Causes

Echolalia is incredibly common and not always indicative of a problem. Most children go through a period of echolalia as they develop and learn to speak properly. However, the symptom can also exist alongside other issues, particularly developmental disorders that cause children to continue repetition much longer. People with autism are susceptible to echolalia. Some experts believe that this is their way of compensating for learning difficulties. Some adults develop echolalia following head trauma or severe amnesia. Anatomically, echolalia may result from damage to the brain’s left hemisphere, as well as issues with motor neurons.
