Autism Can Mask the Warning Signs of Suicide

Nearly every Sunday since he was 7, Connor McIlwain had panicked about going to school the following day.

The noise of barking dogs or crying babies, the demands of school, and the constant fear of being exposed to one of his phobias was a lot for Connor to handle. Diagnosed with autism at age 3, he would get so upset at school that sometimes he would run into the street; on at least one occasion, he narrowly escaped being hit by a car.

Connor’s mother, Lori McIlwain, recorded one of his Sunday-night tantrums when he was 10 to share with his doctor. “Poof me away. Poof me away,” Connor pleads in the audio clip, his voice strained. “I want to leave school forever. Throw me away forever; I really want to go away forever.”

The doctor offered suggestions on how to calm Connor and prescribed medication. Still, one day last year, Connor, then 17 and a sophomore in high school, became particularly distraught after a confrontation with a teacher. “We got the call from the school and picked him up,” McIlwain says. When he got home, he began trying to harm himself. “He told us, ‘I’m ready to die now,’ and said goodbye to us.”

Connor’s parents had often kept him home from school to prevent his dangerous meltdowns, but after this incident, they pulled him out of school for good. “Connor is a talented kid,” McIlwain says, but “no math or science was worth his life.”

Among people Connor’s age, suicide is the second leading cause of death in the United States, according to the U.S. Centers for Disease Control and Prevention: Approximately 6,159 people between the ages of 10 and 24 died by suicide in 2016. Suicide is the 10th leading cause of death across all age groups and one of just three leading causes of death that is on the rise, according to a June report. But it’s unclear what the statistics are for people with autism.

Studies over the past few years hint that suicidal ideation is more common in people with autism than in the general population, but the estimates vary so widely that some experts say they are meaningless. Still, there is some evidence that autistic people are especially vulnerable to suicide: One 2015 study that mined Sweden’s large National Patient Register found that they are 10 times as likely to die by suicide as those in the general population. (Women with autism are particularly at risk, even though men are more so in the general population.)

Even when signs of suicidality are apparent, clinicians may dismiss them.

“I think part of the problem is that we only see things we’re paying attention to,” says Jeremy Veenstra-VanderWeele, a professor of psychiatry at Columbia University. “Until very recently, we didn’t expect to see it, so we didn’t see suicidality in patients with [autism]; it just wasn’t on our radar.”

Clinicians may wrongly assume that people on the spectrum don’t have complicated emotions, or they may discount their outbursts, says Paul Lipkin, the director of the Interactive Autism Network at the Kennedy Krieger Institute in Baltimore, Maryland. “These children feel a normal range of emotions as other children, but [they] don’t do it in a typical way, and they’re not necessarily taken as seriously because they have a wide range of emotions showing already,” he says. Doctors also misinterpret self-harm—a classic warning sign for suicide in the general population—as a part of autism.

All of that is beginning to change. Some teams are adapting tools to spot autistic people who are at risk of suicide and gain a sense of the scale of this problem. Many typical signs of suicidality—changes in sleep, appetite, and social relationships—involve areas that are already challenging for these individuals. So “one can’t rely on these changes in this population,” Lipkin says. Instead, the researchers are looking at the interplay of known risk factors, such as depression, anxiety, and bullying, in autistic people. And they are identifying risks unique to this population, such as social challenges, communication difficulties, and diagnoses of attention-deficit hyperactivity disorder.

Like Connor, many children with autism tend to perform well at school academically but struggle socially. They become isolated from their peers, which can lead to depression.

Children who struggle with social communication are at a high risk of suicidal behavior—even if they do not have autism—as are adolescents who have autism and symptoms of depression, according to a large study published in May in the Journal of the American Academy of Child and Adolescent Psychiatry. The researchers tracked 5,031 children in the Avon Longitudinal Study of Parents and Children, a large birth cohort in the United Kingdom. The children have either been diagnosed with autism or they show at least one of four autism traits: repetitive behaviors, social-communication difficulties, pragmatic-language problems, or a lack of sociability. Those who have problems with social communication were the most likely to harbor thoughts of suicide at age 16, the researchers found.

“This is an urgent and obvious area for further research to try to prevent what we now recognize,” Veenstra-VanderWeele wrote in an editorial accompanying the results.

Other research shows that being bullied is common among young people with autism and may lead to depression and anxiety. In June, a study of the same U.K. cohort found that children with autism traits not only have more signs of depression than typical children at age 10, but that signs of depression persist for at least eight years, especially if a child has been the target of bullying. “Bullying explains 50 percent of the relationship between problems with social communication and a diagnosis of depression,” says the lead investigator, Dheeraj Rai, a senior lecturer at the University of Bristol in the U.K. “We know that people with autism feel victimized after bullying; it’s very common and something many people and their families relate to us.”

Being bullied may also increase the risk of suicide in another way: by increasing aggression. In an unpublished study presented in May at the International Society for Autism Research (INSAR) meeting, a group in the Netherlands looked at experiences with bullying in 185 adolescent boys, 89 of whom have autism. The more victimization the teens faced, the more anger and fear they expressed. Compared with typical boys, though, autistic boys reacted predominantly with anger—a response that could lead to uncontrollable emotional arousal and raise the risk of suicide.

Intense rage can overtake 10-year-old Noah, who was diagnosed with autism at 4. “He’s a big love bug when he wants to be,” says his mother, Theresa McSpadden. But Noah has been bullied repeatedly, which makes him so upset that he acts out. He has twice attempted to harm himself and was hospitalized for suicidal ideation at ages 6 and 8.

When Noah was 9, another boy at his summer camp wouldn’t leave him alone. Noah told the boy to stop and complained to his camp counselor, but to no avail, McSpadden says. Finally, in a fit of anger, Noah threatened to stab the boy. The camp’s staff called the police—and then Noah’s parents. By the time McSpadden arrived, a police officer was on the scene; Noah was terrified and thought the officer was going to take him away. “When I told [the officer] Noah has autism, he told me to stop making excuses,” McSpadden recalls. She took Noah out of the camp immediately. He still makes threats to harm himself when he gets angry, she says, but “we are dealing with it at home right now, with his therapists and his psychiatrist.”

Monica Hatton’s autistic son Jake, 12, also struggles with anger and suicidality. “He turns into the Hulk,” Hatton says, referring to the superhero who transforms from a mild-mannered scientist into a rage-filled ogre. Jake “throws himself or does air fisting and kicking; those are the moments I fear.”

Jake was diagnosed with autism when he was 3. At around age 7, he started saying, “I want to die; I hate myself,” his mother says. Jake would sometimes try to harm himself. Soon after the family moved from their home in Virginia to Connecticut, he spiraled out of control. “He went into an impulsivity rage and tried to grab a knife,” Hatton says. “He wanted to hurt himself; he wasn’t being aggressive toward me or someone else, only to himself. At these moments, he just needs big hugs. We tell him we love him. We cry with him and then the pressure cooker [inside him] releases the pressure.”

The hurts of bullying and social rebuffs may build up over time: Two out of three people diagnosed with autism as adults reported that they have contemplated suicide at some point in their life, according to a large study published in 2014. These adults “had been without support or understanding of autism for a long time,” says Sarah Cassidy, an assistant professor of psychology at the University of Nottingham in the U.K.

For Cheryl, 61, getting an autism diagnosis early in life and learning strategies to address social-communication problems might have made all the difference. “If I was diagnosed as a kid, someone could have helped me,” Cheryl says. (She requested to by identified by only her first name to protect her privacy.)

She says she was ridiculed at school and didn’t have any friends throughout childhood. She was so afraid of being teased that she skipped eating lunch in the cafeteria. People told her she was smart, but she couldn’t converse with them. “When I tried to talk, it was like having my jaw wired shut—it was difficult to push the words out,” she says. “They made fun of me and were really cruel.” At age 15, she attempted suicide and was unconscious for days; she tried again at 17.

After she recovered, she often contemplated suicide again. Her social difficulties made it difficult to hold down a job or keep her marriages together. Nearly 40 years after her initial suicide attempt, Cheryl says she “looked out over all the devastation and waste spanning all the years of my life” and besieged her health-insurance company with requests for help. Finally, at 56, she was diagnosed with autism. “Once I was diagnosed, it was such a tremendous relief. I could stop blaming myself for all my mistakes with people,” she says. “It gave me a new lease on life.”

Not everyone finds that kind of relief. Adults with autism face an elevated risk of suicide even after taking into account a number of known risk factors, such as unemployment, depression, and anxiety, according to an unpublished study Cassidy presented at INSAR in May. “This suggests that there must be other autism-specific risk markers, which must be identified, that explain the increased risk of suicidality in this group,” Cassidy says.

One heavy burden for autistic people to carry is “camouflaging”—the attempt to hide their autism traits to fit in. Adults with autism who camouflage are eight times as likely to harm themselves as those who don’t, Cassidy’s team has found. Although many autistic adults do camouflage, the phenomenon is thought to be particularly common and damaging among women on the spectrum.

The effort involved in camouflaging contributes to anxiety and depression, compounding the risk of suicide. “I struggle to fit in,” says Richard Carmichael, 17, of North Carolina, who was diagnosed with autism five years ago. “I wear neutral-colored clothing; I try to appear normal at all times,” Richard says. Although he no longer feels suicidal, he says, he did for years.
