Most individuals with ASD participate in alternative treatments, which are therapies intended to augment or supplant conventional remedies. Popular alternative treatments for ASD include biomedical interventions such as elimination diets or nutritional supplements and sensorimotor interventions such as swinging or brushing an individual's body. Although little research is available on most of these treatments, some have been found to be unsafe or ineffective. Resources are available to facilitate open communication between practitioners and families about alternative treatments and to help families make informed decisions about them. Over time, efforts to increase access to and quality of conventional care may reduce the impetus for families to seek alternative treatments.
