Current statistics predict one out of every 68 children will be diagnosed with an autism spectrum disorder (ASD). Autism is a neurodevelopmental disability that typically appears within the first three years of life. Individuals with ASD exhibit developmental delays in social and communication development, often have atypical responses to sensations, repetitive behaviors, and intense and/or atypical interests. ASD is about four times more likely in boys than girls, and sometimes occurs in association with other disorders. Though the cause of autism is unknown and cannot be "cured," structured educational programs geared to the child's developmental level and interests can improve outcomes and support improved quality of life.
Dr. Landa directs the Center for Autism and Related Disorders (CARD) at Kennedy Krieger Institute, which offers a uniquely interdisciplinary and comprehensive approach to serving children with ASD and their families. The center combines educational, behavioral, clinical, diagnostic, out-patient and outreach programs to create treatment that is tailored to the particular needs of individual children and their families.
Dr. Landa's research has focused on neuropsychological, learning and communication processes in autism across the lifespan. Her research, clinical, and community-based work for over the past 15 years has focused on identifying the earliest markers and developmental trajectories associated with autism spectrum disorders (ASD) and communication disorders, and translating that knowledge into scalable interventions that can be feasibly implemented in community settings where the greatest impact can be made.
Prior to 2005, researchers, parents, and clinicians relied solely on retrospective studies or case reports to understand the earliest indicators of ASD. Dr. Landa was part of the original research group that determined that ASD was heritable. That same group discovered that there was continuum of ASD characteristics, and that family members of individuals with ASD may exhibit a set of behavioral and information processing characteristics that are similar to those of ASD but much milder. This has been referred to as a ‘broader autism phenotype’. To advance the field’s understanding of the earliest signs of ASD, and how infants with ASD learn (so that more effective treatments could e developed), Dr. Landa pioneered a new research design, involving the study of infant siblings of children with autism and following these infants into their teen years. This prospective longitudinal research approach is known as the ‘high risk siblings’ design. Dr. Landa’s research showed that about 20% of younger siblings of a child with ASD will also have ASD (replicated by the Baby Siblings Resarch Consortium – Ozonoff et al., 2011). Her work showed that motor differences by age 6 months are predictive of ASD and communication delays and that there is a prodromal period for ASD. She also showed that there are different patterns of ASD onset and multiple developmental trajectory patterns in high risk sibs. Out of what she learned in her research with infants at heightened risk for ASD, Dr. Landa developed a brief tutorial of early ASD indicators (see youtube ‘Bringing the Early Signs of Autism Spectrum Disorders into Focus’; Spanish versions also available). Another product from her infant research is the Early Video-guided Autism risk Screener (EVAS), designed to detect autism risk in children from 12 to 60 months of age.
