Light therapy headband shows promise for autism in small trial

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Participants must be deemed not to have impaired decision-making capacity and must have the capacity to provide direct informed consent. Participants must sign an Institutional Review Board-approved informed consent form before initiation of any study procedures. * Participants must have a level of understanding sufficient to communicate with the investigator and study coordinator, and to cooperate with all tests and examinations required by the protocol. * Participant experiencing a major psychiatric disorder will be allowed to participate in the study provided they do not meet any exclusionary criteria. * Women of child-bearing potential must use a double-barrier method for birth control (e.g. condoms with spermicide) if sexually active. * The subject is willing to participate in this study. Exclusion Criteria: * Impaired intellectual capacity (clinically determined).
