High Recurrence Risk for Autism in Siblings

A research study published in the journal Pediatrics suggests that nearly 1 in 5 children who have an older sibling with autism will also develop the disorder at a rate much higher than previously thought. Earlier estimates put the risk at between 3 and 10%, but a new study found a substantially higher risk rate of 18.7%, on average.
Researchers in the U.S., Canada and Israel followed 664 infants from 12 US and Canadian sites who had at least one older brother or sister with an autism spectrum disorder. Overall, 132 infants or approximately 19% received an autism diagnosis by their third birthday.
The highest rates were in infants who had at least two older siblings with autism – 32% also developed the disorder. Boys were nearly three times as likely to develop autism as girls, with a recurrence rate of 26.2% versus 9.1%.
The study’s lead author Sally Ozonoff, a psychiatry and behavioral sciences professor with the Mind Institute at the University of California at Davis, noted that 80% of siblings studied did not develop autism, and that the prevalence rate was an “average.” According to Ozonoff, “It’s important to recognize that these are estimates that are averaged across all of the families. So, for some families, the risk will be greater than 18 per cent, and for other families it would be less than 18 per cent.”  “At the present time, unfortunately, we do not know how to estimate an individual family’s actual risk.”
The study has important implications for both parents and professionals.  Families and primary care professionals should be especially observant with infants whose older siblings have been diagnosed with an autism spectrum disorder. Early identification and intervention are critically important to outcome. Ozonoff and her colleagues comment, “The red flags identified should be followed by immediate referral for infant intervention rather than adopting a 'wait-and-see' attitude because early specialized intervention is considered best practice for ASD and may represent the best hope for reducing symptoms and overall disability in high-risk infants who are developing ASD."

Legally Appropriate Educational Services for Students with ASD

Since Congress added autism as a disability category to the Individuals with Disabilities Education Act (IDEA) in 1990, the number of students receiving special education services in this category has increased over 900 percent nationally. It’s critically important that educators understand the provisions for providing legally and educationally appropriate programs and services for students identified with ASD.
 Research indicates that education is the most effective treatment/intervention for children with ASD. The most recent reauthorization of the Individuals with Disabilities Education Act (IDEA 2004) <http://idea.ed.gov/explore/home >entitles all students with disabilities to a free, appropriate public education (FAPE). FAPE encompasses both procedural safeguards and the student’s individual education program (IEP). The IEP is the cornerstone for the education of a child with ASD. When a student is determined eligible for special education services, an IEP planning team is formed to develop the IEP and subsequently determine placement.
Although clinical diagnoses, psychiatric reports, and treatment recommendations can be helpful in determining eligibility and educational planning, the provisions of IDEA are the controlling authority with regard to decisions for special education. While clinical information is professionally helpful, it is neither legally required nor sufficient for determining educational placement. Therefore, it’s especially important for administrators, parents, advocates, teachers and non-school professionals to keep in mind that when it comes to special education, it is state and federal education codes and regulations (not clinical criteria) that determine eligibility and IEP planning decisions. Legal and special education experts recommend the following guidelines to help school districts meet the requirements for providing legally and educationally appropriate programs and services to students with ASD.
1. School districts should ensure that the IEP process follows the procedural requirements of IDEA. This includes actively involving parents in the IEP process and adhering to the time frame requirements for assessment and developing and implementing the student’s IEP.  Moreover, parents must be notified of their due process rights. It’s important to recognize that parent-professional communication and collaboration are key components for making educational and program decisions.
2. School districts should make certain that comprehensive, individualized evaluations are completed by school professionals who have knowledge, experience, and expertise in ASD. If qualified personnel are not available, school districts should provide the appropriate training or retain the services of a consultant.
3. School districts should develop IEPs based on the child’s unique pattern of strengths and weaknesses. Goals for a child with ASD commonly include the areas of communication, social behavior, adaptive skills, challenging behavior, and academic and functional skills. The IEP must address appropriate instructional and curricular modifications, together with related services such as counseling, occupational therapy, speech/language therapy, physical therapy and transportation needs. Evidence-based instructional strategies should also be adopted to ensure that the IEP is implemented appropriately.
4. School districts should assure that progress monitoring of students with ASD is completed at specified intervals by an interdisciplinary team of professionals who have a knowledge base and experience in autism. This includes collecting evidence-based data to document progress towards achieving IEP goals and to assess program effectiveness.
5. School districts should make every effort to place students in integrated settings to maximize interaction with non-disabled peers. Inclusion with typically developing students is important for a child with ASD as peers provide the best models for language and social skills. However, inclusive education alone is insufficient, evidence-based intervention and training is also necessary to address specific skill deficits. Although the least restrictive environment (LRE) provision of IDEA requires that efforts be made to educate students with special needs in less restrictive settings, IDEA also recognizes that some students may require a more comprehensive program to provide FAPE. 
6. School districts should provide on-going training and education in ASD for both parents and professionals. Professionals who are trained in specific methodology and techniques will be most effective in providing the appropriate services and in modifying curriculum based upon the unique needs of the individual child.
