Relation to autism: Crystal children, a concept related to indigo children, has been linked by autism researcher Mitzi Waltz to the autism spectrum. Proponents recategorize autistic symptoms as telepathic powers, and attempt to reconceptualize “the autistic traits associated with them as part of a positive identity". Waltz states that there may be inherent dangers to these beliefs, leading parents to deny the existence of impairments, avoid proven treatments and spend considerable money on unhelpful interventions. Waltz states that "Parents may also transmit belief systems to the child that are self-aggrandizing, confusing, or potentially frightening".
