9. Other Disorders
Certain medical conditions may predispose children to develop autism. Genetic conditions linked to autism include fragile X syndrome and Rett syndrome, both of which cause intellectual disabilities. Tuberous sclerosis, a condition in which benign tumors appear in the brain, is also associated with the occurrence of autism.11‘Autism Spectrum Disorder.’ Mayo Clinic, Mayo Foundation for Medical Education and Research, 6 Jan. 2018, www.mayoclinic.org/diseases-conditions/autism-spectrum-disorder/symptoms-causes/syc-20352928.
Epilepsy is more common in those with autism. Up to 30 percent of people with autism develop epilepsy by the time they become adults.1‘Autism Spectrum Disorder Fact Sheet.’ National Institute of Neurological Disorders and Stroke, U.S. Department of Health and Human Services, www.ninds.nih.gov/Disorders/Patient-Caregiver-Education/Fact-Sheets/Autism-Spectrum-Disorder-Fact-Sheet#3082 5.
