What Is the Leading Cause of Death in Autism? Understanding Safety Risks

Martin Klein • March 11, 2026

Safety is an important topic for families raising a child with autism. Studies show that accidental injuries are a significant risk, with drowning identified as one of the leading causes of death among autistic children. This risk is often linked to wandering behavior—sometimes called elopement—and a strong attraction to water.


Many autistic children enjoy sensory experiences such as the visual movement or the sound of water. Because of this, lakes, ponds, swimming pools, or even fountains can become particularly appealing. If a child wanders away unnoticed, the situation can become dangerous very quickly.


Prevention strategies are essential. Families are encouraged to install secure locks, alarms, or fences around pools and water areas. Teaching swimming and water safety skills at an early age can also be extremely valuable. In addition, helping children learn safety behaviors—such as responding when their name is called or staying within sight of caregivers—can reduce risk.


Behavioral support can play a key role. At Achieve Behavioral Therapy, ABA-based strategies are used to teach safety awareness, communication skills, and responses to potentially dangerous situations. By building these skills step-by-step, children gain tools that help them navigate their environment more safely and confidently.
