In the first study of Autism in Mexico, Lead Researcher, Dr. Eric Fombonne, in his recently published study, "The Prevalence of Autism Spectrum Disorders in Guanajuato, Mexico; the Leon Study'*, "the study leads us to believe that there may be up to 400,000 children and adolescents affected by autism and in need of services."
"Of particular interest is that Mexican children with autism are being diagnosed at a very late age ..." says Dr. Fombonne. He adds that nearly 78 percent of the children with autism did not receive their diagnosis until age 3. Another 22% went undiagnosed until age 5.
Research tells us that autism can be reliably diagnosed as early as ages 18 to 24 months. Diagnosis at age 3 leaves autistic children with 12 to 18 months without access to services and therapies.
Dr. Sappa Parikh reported on ABC local that Latino children with autism are diagnosed 2.5 years later than other children in the United States.
According to Lisa Shulman of NYC's Albert Einstein's College of Medicine in her 2015 study of early intervention with autistic children, she indicates that early intervention can help one of 14 toddlers overcome symptoms of autism. Many of these children will still require special education services for emotional, behavioral or learning issues.
