Solitary confinement can be detrimental for inmates of any age, but the developing brains of juveniles make them especially vulnerable to long-lasting mental health problems, according to an article in The Atlantic.

It wreaks profound neurological and psychological damage, causing depression, hallucinations, panic attacks, cognitive deficits, obsessive thinking, paranoia, anxiety, and anger. Boston psychiatrist Stuart Grassian wrote that “even a few days of solitary confinement will predictably shift the [brain impulse] pattern towards an abnormal pattern characteristic of stupor and delirium.”

The story was prompted by a report released by the American Civil Liberties Union, entitled, “Alone & Afraid: Children held in solitary confinement and isolation in juvenile detention and correctional facilities.”

About 70,000 juveniles are detained on any given day in the United States, according to the ACLU report, which compiled its findings from a variety of government and private-sector sources.

More than 10 years ago, 35 percent of detained juveniles had been held in solitary confinement, and half of them had been isolated for more than 24 consecutive hours. Those 2003 figures were the most recent survey data made available by the Department of Justice to the authors of the ACLU report.

The ACLU concluded:

Laws, policies, and practices must be reformed to ensure that more effective, safer alternatives are utilized with children in the juvenile system, and that our priority is their proper protection and rehabilitation.

The Atlantic reports that no states ban the use of solitary confinement for children in adult facilities and only a few states limit it in juvenile facilities.

For teenagers and even inmates in their 20s, the isolation can threaten the parts of their brains that make plans and determine what actions to take as well as those portions that control impulses.

“The experience of isolation is especially frightening, traumatizing, and stressful for juveniles,” he [Craig Haney, a professor of psychology at the University of California Santa Cruz] said. “These traumatic experiences can interfere with and damage these essential developmental processes, and the damage may be irreparable.”

James Baldwin wrote, “Not everything that is faced can be changed, but nothing can be changed until it is faced.” PublicSource exists to help the Pittsburgh region face its realities and create opportunities for change. When we shine a light on inequity in our region, like the “completely unacceptable” conditions in low-income housing in McKeesport, things change. When we ask questions about policymakers’ decisions, like how Allegheny County is handling COVID-19 safety for its employees, things change. When we push for transparency on issues that affect the public, like in the use of facial recognition software by Pittsburgh police, things change.

It takes a lot of time, skill and resources to produce journalism like this. Our stories are always made available for free so that they can benefit the most people, regardless of ability to pay. But as an independent, nonprofit newsroom, we count on donations from our readers to support this crucial work. Can you make a contribution of any amount (or better yet, set up a recurring monthly gift) to help ensure we can continue to report on what matters and tell stories for a better Pittsburgh?
