Frequent behavioral crises shorten lives through multiple overlapping pathways: chronic stress that damages organs and the brain, medications with serious side effects, barriers to routine medical care, dangerous encounters with law enforcement, and the erosion of support systems that keep people safe. For individuals with autism spectrum disorder, intellectual disabilities, or serious mental illness, these factors compound over years and decades. One U.S. study found that people with autism died an average of 38.5 years earlier than their life expectancy, with health status and level of daily living independence being the strongest predictors of early death.
Chronic Stress Damages the Body From the Inside
Every behavioral crisis triggers the body’s stress response, flooding the system with cortisol. In a single acute episode, cortisol is helpful: it raises blood sugar, sharpens focus, and prepares the body to respond to a threat. But when crises happen frequently, cortisol stays elevated for long stretches, and the system that’s supposed to regulate it starts breaking down.
Over time, the brain’s stress-regulation system becomes desensitized. The body develops resistance to cortisol’s normal anti-inflammatory signals, which leads to a paradoxical state: stress hormones remain high, but they stop doing their protective work. The result is persistent, unresolved inflammation throughout the body and brain. This chronic inflammatory state is implicated in a wide range of serious conditions, including heart disease, diabetes, and neurodegenerative disorders.
The brain itself takes direct hits. Chronic cortisol exposure causes atrophy in the hippocampus, a region critical for memory and emotional regulation, and increases oxidative stress and mitochondrial dysfunction in neurons. Animal research has shown that sustained cortisol release accelerates the accumulation of the proteins associated with Alzheimer’s disease. Cortisol can actually bind to genes involved in producing these toxic proteins, directly influencing their buildup. Similar mechanisms link chronic stress to the progression of Parkinson’s disease through damage to dopamine-producing neurons. For someone experiencing behavioral crises weekly or even daily, this neurological wear and tear accumulates across years in ways that would not occur in a lower-stress life.
Medications Used to Manage Crises Carry Their Own Risks
People who experience frequent behavioral crises are often prescribed heavy regimens of psychotropic medications, sometimes multiple drugs simultaneously. Antipsychotics, benzodiazepines, and antidepressants are commonly used to reduce the frequency or intensity of episodes. Each class of medication carries mortality risks that increase with long-term use.
In placebo-controlled trials involving patients with dementia, antipsychotics were associated with a 1% higher absolute death rate compared to placebo. Benzodiazepines and related drugs doubled the overall death rate in one well-conducted cohort study of middle-aged patients, translating to roughly 1% excess mortality per year. Newer antidepressants were linked to a 3.6% increase in all-cause mortality over one year in adults over 65. Falls are a particularly dangerous side effect of psychotropic drugs in older populations and a significant contributor to these deaths.
For individuals who begin these medications in childhood or early adulthood and remain on them for decades, the cumulative risk is substantial. Many people in behavioral crisis are on not just one but several of these drugs at once, compounding the metabolic effects: weight gain, insulin resistance, cardiovascular strain, and sedation that limits physical activity. The medications prescribed to keep someone safe in the short term can quietly erode their physical health over the long term.
Routine Medical Care Becomes Hard to Access
One of the less visible ways frequent crises shorten lives is by creating barriers to basic healthcare. People who may become agitated, distressed, or unable to cooperate in a clinical setting often find that providers are reluctant or unable to see them. Surveys have found that two-thirds of primary care physicians could not secure outpatient mental health services for their patients, and the barriers multiply for individuals with complex behavioral needs.
These barriers span several categories: providers who feel inadequately trained to manage behavioral challenges, a lack of culturally competent care for vulnerable populations, difficulty coordinating treatment for people with multiple physical and mental health conditions, and chronic shortages of specialists willing to take on complex cases. The practical consequence is that treatable conditions go undiagnosed. A dental infection, rising blood pressure, early-stage diabetes, or a slow-growing cancer that would be caught in a routine visit for someone else may go unnoticed for months or years. By the time these conditions are identified, they’ve often progressed to a point where treatment is more difficult and outcomes are worse.
This diagnostic delay is compounded by communication challenges. Many individuals who experience frequent behavioral crises have difficulty describing pain or new symptoms verbally, meaning their caregivers and providers must rely on behavioral cues. When a person’s baseline already includes distress behaviors, a new source of pain can easily be misattributed to “just another episode” rather than recognized as a medical symptom requiring investigation.
Law Enforcement Contact Creates Direct Physical Danger
Behavioral crises frequently result in calls to emergency services, and in many communities, law enforcement is the first or only responder. An estimated 7 to 31% of all police calls in the United States involve a person showing signs of a mental health disorder. These encounters carry disproportionate risk: individuals displaying signs of mental illness are more than seven times more likely to be killed in police shootings compared to others.
Beyond the immediate danger, contact with law enforcement often triggers involvement with the criminal justice system. People with serious mental illness are overrepresented in prisons and jails, and incarceration itself is a well-documented driver of poor health outcomes. Each crisis that results in a police call represents a moment of acute physical risk, and for someone experiencing crises regularly, these moments accumulate into a pattern of repeated exposure to potentially lethal force and the health-damaging effects of detention.
Support Systems Break Down Over Time
Caring for someone who experiences frequent behavioral crises is physically and emotionally exhausting. Family caregivers face elevated rates of burnout, depression, and their own chronic health problems. Professional caregivers in group homes and residential settings experience high turnover, meaning that the people who know an individual best and can read their early warning signs are constantly being replaced by staff who cannot.
This instability creates a dangerous feedback loop. New or burned-out caregivers are less able to implement the proactive strategies that prevent crises, which leads to more crises, which drives more turnover. The loss of consistent, skilled support increases the likelihood that an individual will end up in more restrictive settings, including psychiatric hospitals or long-term institutional care, where health outcomes tend to be worse and autonomy is reduced.
Greater levels of independence in daily living are directly tied to survival. A 20-year study of individuals with autism found that for every one-point increase on a measure of daily living independence, the risk of dying over the study period dropped by 6.5%. Conversely, greater social impairment at a young age predicted a 27% higher mortality risk per point on the impairment scale. When support systems collapse and independence declines, the trajectory bends sharply toward earlier death.
How These Factors Compound
No single mechanism fully explains why frequent behavioral crises are life-limiting. The danger lies in how these pathways reinforce each other. Chronic stress weakens the body. Medications add metabolic strain. Healthcare avoidance allows diseases to progress. Law enforcement encounters create trauma that worsens behavioral episodes. Caregiver burnout reduces the quality of daily support, which increases crisis frequency, which restarts the cycle.
A Danish cohort study found that individuals with autism died at twice the expected rate of the general population. A U.S. analysis using electronic health records found that people with autism had higher rates of most health conditions and died roughly 20 years earlier than matched controls. The individuals in greatest danger are those with the most impaired functioning, the fewest supports, and the least access to proactive, consistent care. Reducing the frequency of crises through environmental modifications, skilled support, and appropriate intervention doesn’t just improve quality of life. It is, in the most literal sense, lifesaving.
