Most people have experienced some type of trauma in their lives and have subsequently felt aftereffects from the trauma, which we have come to term posttraumatic stress. If the posttraumatic stress is persistent and impairs functioning, it can become a disorder. But many different types of posttraumatic stress symptoms exist, and we continue to refine which symptoms constitute posttraumatic stress disorder (PTSD). The latest refinement occurred in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). The DSM-5 introduced several new PTSD symptoms and tinkered with a few previously described symptoms to better define how to diagnose the disorder. However, how these new and refined symptoms cluster with other symptoms was unclear. Knowing how different symptoms of PTSD cluster together would help us conceptualize the major symptom components of the disorder. When symptoms often overlap with others, they presumably together represent a broader symptom component. To make a medical analogy, when symptoms of a sore throat, cough, and excess phlegm are found together, they represent disruptions in the respiratory system that can mean the patient has a cold.

Veterans are an important and ideal population in which to study posttraumatic stress not only because of their higher potential exposure to trauma than the general public but also because we care about the well-being of those who have served. So, my colleagues and I conducted a study using a nationally representative sample of 1,484 US veterans to understand the prevalence of DSM-5 PTSD, the major symptom components of the disorder, and how different symptom components are related to important outcomes. Using a web-based survey, we assessed various mental health symptoms, including those of PTSD, and other aspects of their lives, such as quality of life.

We found that 12% of US veterans screened positive for lifetime DSM-5 PTSD and 5.2% screened positive for past-month DSM-5 PTSD. In analyzing how DSM-5 PTSD symptoms cluster, we found 6 major symptom components that we called re-experiencing symptoms, avoidance symptoms, emotional numbing symptoms, externalizing behaviors, dysphoric arousal symptoms, and anxious arousal symptoms. Furthermore, we found that these major symptom components were related to different outcomes. For example, emotional numbing symptoms were more strongly related to depression, suicidal thoughts, and decreased quality of life than other symptom components, and externalizing behaviors were more strongly related to hostility than other symptom components.

These findings may help further efforts to understand, diagnose, and treat PTSD. Different symptom components may exist differently in our neurobiology, making some better targets for certain treatments than others. Because PTSD is a complex disorder, we should expect to continually refine how we understand and conceptualize it.

How Does Neuroscience Research Relate to Psychoanalysis?

Basic neuroscience research is sometimes, but mistakenly, thought to be singularly devoted to finding medications that will treat neurologic and psychiatric diseases. Although some basic neuroscience does suggest new molecular targets for medications, perhaps an even greater proportion of this research has helped us to understand the enduring effects of stress and potential psychosocial remedies. In fact, neuroscience research now appears capable of validating and exploring two of the central pillars of psychoanalytic theory: (1) that much of mental life is unconscious but nevertheless fully capable of affecting waking emotion and behavior and (2) that early life experiences have important implications for adult function and happiness.

An interesting example of a way in which neuroscience research may relate to psychoanalysis is the molecular biology of conditioned fear memory reconsolidation. In the laboratory, rats and mice can fairly easily be conditioned to fear a conditioned stimulus, like a loud tone, if it is paired a few times with an unconditioned stimulus, such as a mild electric shock. After conditioning, the animal responds to the tone by freezing in place, just as it did when given the shock. The process by which fear conditioning becomes part of permanent memory is called consolidation and requires a chain of molecular events, including gene expression and protein synthesis, in the amygdala. Blocking these events during conditioning, such as by administering a protein synthesis inhibitor like anisomycin, prevents the consolidation of fear memory, and no conditioned response can subsequently occur.

The amygdala is also activated in humans when they are presented with fearful stimuli. Patients with anxiety disorders have especially robust amygdala activation when their brain activity is monitored with functional magnetic resonance imaging (fMRI). Conditioned fear in rats responds to selective serotonin reuptake inhibitors (SSRIs) in almost the same temporal pattern as is seen in anxious patients. Thus, conditioned fear in animals is considered by many to be a model of human fear and anxiety.

Conditioned fear responses can be extinguished if the conditioned stimulus is presented multiple times without reinforcement by the unconditioned stimulus. That is, if the tone is presented to the rat over and over again without any electric shock, the animal eventually stops freezing. In this case, it has learned that tone and shock are not paired, a process that involves both the medial prefrontal cortex (mPFC) and the amygdala. But, importantly, the original fear memory is not abolished; rather, the original memory and the new extinction memory exist side by side in a delicate balance. At first, extinction dominates, and the animal does not freeze to the tone, but, after a period of time of no testing, the conditioned fear response can be easily reactivated by a single presentation of the conditioned stimulus.

In 2000, Karim Nader, PhD, and colleagues published a seminal article showing that a reactivated fear memory is temporarily labile and can be blocked from re-entering permanent memory. For the inactive memory to be returned to permanent memory, it must go through the consolidation process all over again. If this reconsolidation is blocked, for example as Nader and colleagues did by administering anisomycin right after memory reactivation, the animal will subsequently not freeze when the tone is presented. What is critically different between extinction and reconsolidation blockade, however, is that in the latter case the fear memory is permanently abolished.

In a 2011 article , Steven P. Roose, MD, and I proposed that psychoanalytic interpretations function in a manner similar to blocking the reconsolidation of fear memory. During psychoanalytic therapy, the patient gradually recovers memory of unconscious conflicts based on early traumatic experiences. When these memories become conscious, we speculated, the memories are labile. Psychoanalytic interpretation reframes them so that, when they are reconsolidated into permanent memory, they are no longer as disturbing and capable of producing negative or aversive emotions and self-destructive behavior. Hence, a successful interpretation should offer patients some measure of permanent relief.

Psychoanalysis is a complex theory, and no single model can ever truly be said to be an adequate model. But the idea that at least one aspect of psychoanalysis may be represented in the laboratory opens up intriguing possibilities for experimental study. I hope the reconsolidation hypothesis stimulates thinking about the neuroscientific basis of psychotherapy.

Alzheimer’s Care: It Starts With a Conversation and Involves Everyone

Almost all clinicians will see a patient with symptoms of Alzheimer’s or another dementia at some point in their careers, either in an outpatient or inpatient setting. According to the latest figures from the Alzheimer's Association , there are 5.1 million Americans aged 65 years and older with the disease, and that number will climb to more than 13.8 million by 2050. Yet only 45% of Alzheimer’s patients or their caregivers report that they received the initial diagnosis directly from their doctor.

Giving a patient this diagnosis is undoubtedly among the most difficult conversations a doctor may ever have. The first time I ever told a patient that she had Alzheimer’s, it didn’t go well. I’m sure I squirmed and used some vague and evasive language. But, after decades of experience with Alzheimer’s patients, I can now confidently say that patients are grateful when their doctor is direct and honest about what is happening. They can face the facts. They can work with their clinicians and their families to plan what’s next, explore what treatments are available, and determine how they will try to shape their new lives.

While “what’s next” involves both medical and nonmedical interventions, we at Banner Alzheimer’s Institute (BAI) believe that about 80% of what is needed is the nonmedical assistance for the patient, caregiver, and family. This approach, part of our “Model of Care,” is centered on both the patient and family and is consistent with guidelines such as those published by the American Psychiatric Association in its October 2014 Guideline Watch for the treatment of patients with Alzheimer’s and other dementias.

Based on years of experience in caring for these patients, we have now developed a model for the primary care setting called the “Dementia Care Initiative.” In this model, primary care providers are trained to evaluate a patient for a diagnosis of Alzheimer’s disease or another dementia; determine if it’s mild, moderate, or advanced; and then implement a treatment plan that is a mix of interventions that successfully address a patient’s needs in terms of behavior and psychological state, daily function, cognition, and stimulation. This checklist-type plan is tailored to the severity of the patient’s dementia and his or her unique needs.

For example, a primary care physician will see a patient with mild dementia and identify potential triggers for depression, anxiety, and irritability. A case worker will work with this patient to assess his ability to perform activities of daily living and will provide the patient with educational resources and review topics such as power of attorney and long-term care.

For a patient who has moderate Alzheimer’s, these interventions go one step further. The physician will evaluate the patient for any new behavioral problems and determine the need for medications. The case manager will assess any changes in the patient’s ability to perform activities of daily living and recommend additional help, if needed, for tasks such as meal preparation and personal care. The case manager will also continue to discuss the importance of a power of attorney and, if the patient lives alone, ensure that the patient is placed in a more secure setting.

We know how important it is not only to educate family and caregivers about the progression of the disease and equip them to help the patient, but also how important it is to help teach caregivers how to take care of themselves. The success of BAI’s Model of Care and the primary-care-setting Dementia Care Initiative is due in large part to the simple act of listening to patients and family members and giving priority to their most pressing needs. Time and time again, patients and family members tell us that they feel relieved to know that they have really been heard. They are relieved that clinicians are finally listening to both the patient and family, working with them to help them fully understand what they will all be going through, and helping to improve patients’ quality of life and maintain their dignity.

<span class="svspan">StrongVeterans.com Blog</span>Inadequate Trials of Prazosin: Potential Missed Opportunities for Veterans With PTSD

The 2010 VA/DoD Clinical Practice Guideline recommends that clinicians consider the use of prazosin, an alpha 1 adrenergic receptor antagonist used to treat hypertension, for PTSD-related nightmares. Sleep problems are common in PTSD and may be a core feature. Research has suggested that, although prazosin has been steadily disseminated in the VA, it still may be underutilized and underdosed. In our recent study, we examined a cohort of veterans with PTSD initiating prazosin to characterize their dosing patterns and duration of use.

Administrative data identified veterans with PTSD according to ICD-9 codes. Prazosin use following initiation utilized refill data, and prazosin doses were calculated based upon total milligrams and day’s supply dispensed.

A total of 12,844 veterans with PTSD were new prazosin users during 2010. On average, the patients were 53 years of age, 92% male, and taking 6 medications at the time of prazosin initiation.

Prazosin doses generally increased during treatment, reaching an average maximum dose of 3.6 mg/d. However, only 14% reached the minimum guideline-recommended dose of 6 mg/d for an adequate trial.

Regarding duration of use, 20% of the patients never refilled their initial prazosin prescription, and 18% discontinued within 6 months. The remaining 61% took prazosin for more than 6 months, with 38% of the total sample persisting for at least 1 year. Patients with concurrent SSRI/SNRI antidepressants were more likely to maintain prazosin treatment for a year compared to non-antidepressant users. Additionally, one-year users were older and had more concurrent medications.

Recent work by Murray A. Raskind, MD, and colleagues has noted that pretreatment physiological parameters such as blood pressure in patients with PTSD may serve as a clinically useful biomarker for helping to predict the response to prazosin. Patients who had higher baseline blood pressure and smaller baseline blood pressure drop (standing for 2 minutes for supine) showed substantially greater PTSD symptom improvement associated with prazosin treatment. Although preliminary, these findings suggest that increased peripheral noradrenergic tone is a potential biomarker for a clinically therapeutic response to prazosin in PTSD, and they may also account for varied findings using prazosin for nightmares.

Although large pharmacy databases are very useful for addressing some questions, they cannot answer others. In the present case, we don’t know why the drug was discontinued after one year in two-thirds of the patients. Was it because patients and/or providers found it ineffective at lower doses? Was it because of side effects? Was it because prescribers did not titrate the dose to optimal levels to achieve full symptom response?

Our findings justify further investigation to identify factors related to the common failure to reach recommended prazosin dosage guidelines for PTSD-related nightmares. The answer to this question and others would provide clinicians who treat patients with PTSD a vital opportunity for more optimal use of this low-cost, guideline-recommended treatment.

Pellagra: Niacin Deficiency and Mental Illness

In our previous post, we stated that a single nutrient is unlikely to have a profound effect on a serious mental health condition, but the fascinating story of niacin and pellagra is an exception to that rule.

Pellagra (meaning rough skin) was first described in 1735 by a Spanish physician, Don Gaspar Casal, and was called “mal de la rosa” due to the characteristic red rash on the hands and feet. Early researchers linked pellagra with poverty and a corn-based diet, suggesting that spoiled maize was at fault. Almost 2 centuries later, a pellagra epidemic occurred in the southern United States. Despite the link to the poor person’s diet , the wisdom at that time was that pellagra was contagious and perhaps hereditary, and pellagrins, as they were called, were shunned.

The relevance of pellagra to psychiatry is that symptoms can include confusion, psychosis, and depression. Pellagra typically affects the skin, the gut, and the brain, with a characteristic manifestation referred to as the 3 Ds—dermatitis, diarrhea, and dementia—and it may lead to death.

In 1914, Joseph Goldberger, a physician and clinical epidemiologist, was invited by the US Surgeon General to investigate pellagra. Careful reviews of the literature indicated to him that pellagra was a dietary disease , not an infectious one. Cases were being reported in mental hospitals and orphanages in which the residents, eating a mainly corn-based diet, would get the disease, whereas the staff, despite daily contact with the patients, would not. Outbreaks also appeared in cotton mill villages where the diet was mostly cornmeal, molasses, salted pork, and lard.

Goldberger began running trials in orphanages and asylums by manipulating their diets, and those given fresh meat, milk, and legumes were no longer sick. He also conducted experiments in which he showed he could induce pellagra in healthy men (prisoners who were offered pardons for participating) by feeding them a corn-based diet. Thus, Goldberger established that pellagra was a disease of a faulty diet, not infection.

Despite his repeated controlled experiments using diet manipulation, people continued to hold to the prevailing wisdom that pellagra was infectious. And so, in 1916, he and volunteers (his wife being one of them) were exposed to the blood, urine, feces, and epidermal scales of people with pellagra, and not a single person developed it. Goldberger, however, was unable to isolate the ingredient that was causing the condition. In 1937, another scientist, Conrad Elvehjem, determined that niacin was the essential dietary factor. Fortification of food with niacin began in 1941.

Although underreporting of pellagra was typical, records suggest that at least 3 million cases had occurred, with over 100,000 deaths, in America in the 40 years until its true cause was determined. One state hospital, in Goldsboro, NC, estimated that nearly 1 in 5 admissions between 1930 and 1932 were solely because of pellagra psychosis, an easily preventable/treatable nutrient deficiency.

The Diagnostic and Statistical Manual of Mental Disorders acknowledges that nutritional conditions such as niacin deficiency can cause neurocognitive disorders. But, we wonder, while niacin therapy has been accepted for the eradication of pellagra, is it not possible that a combination of nutrients may have had far superior effects? And, if Walter Mertz was correct when he declared in 1994 that the era of single-nutrient cures for disease was over, what other mental symptoms might be eradicated with combinations of nutrients as treatment? We will cover these topics in future blog entries.

<span class="svspan">StrongVeterans.com Blog</span>PTSD in US Veterans

Posttraumatic stress disorder (PTSD) is a psychiatric disorder that can develop after a traumatic or extremely stressful event, such as military combat, a physical or sexual assault, or a serious accident. PTSD symptoms include problems such as re-experiencing the trauma in the form of intrusive memories or nightmares, not wanting to think or talk about what happened, having persistent negative thoughts and feelings, and feeling “on guard” or vigilant for threat.

The history of the PTSD diagnosis in the United States is intertwined with US military history; in fact, PTSD was added to the Diagnostic and Statistical Manual of Mental Disorders in 1980 largely due to research on psychological problems facing Vietnam veterans. Although much research has been conducted on PTSD among convenience samples of active duty members and veterans, few contemporary studies have examined the prevalence and correlates of PTSD in nationally representative samples of US veterans, which is necessary to draw conclusions about the entire population of veterans in our country. Consequently, surprisingly little is known about how prevalent PTSD is in the current population of US veterans, how often US veterans are exposed to different types of traumas, how frequently other types of psychiatric disorders co-occur with PTSD, and what types of sociodemographic, military, and psychosocial factors are associated with PTSD in this population.

In the National Health and Resilience in Veterans Study, we examined the prevalence of trauma exposure, PTSD, and other psychiatric problems in a contemporary, nationally representative sample of 3,157 US veterans. We found that 8.0% of veterans screened positive for PTSD in their lifetimes, a rate slightly higher than those observed in the general US adult population by Pietrzak et al and Kessler et al (6.4% to 6.8%). Lifetime probable PTSD rates were higher among female veterans (19.4 % vs. 6.8% in men) and among younger veterans (23.8% in those aged 21–29 years versus 3.5% in those aged 60 years or older).

Although clinicians working with veterans often assume that veterans’ PTSD symptoms result from military combat, the veterans in our study frequently reported that their PTSD symptoms resulted from other types of trauma, such as physical or sexual assault during childhood. In fact, the trauma type that veterans most frequently endorsed as their “worst” traumatic experience was the sudden death of a loved one (27.5%), a finding consistent with other research in the general US population. Relative to veterans without PTSD, veterans with PTSD were 2.3 to 19.1 times more likely to screen positive for psychiatric problems, such as depression, anxiety, or alcohol and drug problems, and 9.7 to 11.8 times more likely to endorse suicidal thoughts and behaviors. However, veterans who endorsed protective psychological and social factors, such as greater resilience, community integration, and supportive relationships, were less likely to report PTSD symptoms.

This study indicates that PTSD is a prevalent disorder among both combat and noncombat veterans in the United States, particularly among female and younger veterans, and is associated with high rates of co-occurring psychiatric problems. Interventions designed to increase protective psychosocial factors may help mitigate PTSD risk among US veterans, although further research is needed to examine this possibility.

Costs of Depression in the Workplace

Over the past two decades, together with my colleagues, I have undertaken many assessments of the costs of depression. One robust finding from this body of research, which is echoed in my latest study, is the enormity of the workplace burden of illness. A variety of reasons explain why this particular cost component is so large, with more than half of the costs of depression attributable to workplace productivity losses.

Depression is a highly prevalent, chronic illness that affects people especially in their prime working-age years. Furthermore, many of its symptoms can be highly impairing, particularly from a workplace perspective, whether the needed skills require strength, dexterity, concentration, or interpersonal capability. These symptoms include the following:

  • cognitive impairments, due to reduced ability to focus
  • behavioral impairments, due to social withdrawal or lack of motivation to accomplish even routine tasks
  • physical impairments, due to bodily pain or fatigue
  • emotional impairments, due to increased moodiness or irritability

In many cases, the symptoms of illness are not so severe that sufferers withdraw entirely from the labor force, resulting in a very sizable pool of depressed workers at any given time. Because of this particularly problematic constellation of disease-specific factors, no employer is exempt from the adverse consequences of depression in the workplace.

Employability for individuals with depression changes at different points in the business cycle. When the economy is growing, people with depression tend to remain employable. But, in periods of economic decline, employees with depression bear a disproportionate burden compared with their nondepressed counterparts, especially among those aged 50 years and older. This is both because employees with depression are generally more likely to lose their jobs during economic downturns and because the buffer of part-time work is not as widely available to those with depression. Of course, distinguishing cause and effect in this context is difficult since the presence of depression is likely to diminish labor market attachment, even as unemployment itself could contribute to a more fragile state of emotional well-being.

All of these workplace findings highlight a tension that exists between societal interests and those of individual employers in the context of optimal patient management. On the one hand, society is better served when depressed workers are drawn into employment situations, as the opportunity cost of their lost productive capacity is at least partially recaptured through their newfound labor market activity. In addition, for some depression sufferers, health care coverage is available only via employers. On the other hand, individual employers tend to incur added costs as the employment rate of depressed people rises.

Thus, the complex interplay of work status, depression symptoms, and depression treatment warrants continued study. Shining a bright light on the relative impact of these different contributors to direct cost changes and understanding how they have moved historically would offer insight into the available levers that could be brought to bear in most effectively managing resource utilization in this context over time.

Assessing Patients’ Capacity to Refuse Medical Care

Few people dispute the assertion that in a free society we all have the right to make our own mistakes—including our right as patients to refuse care we do not want. Indeed, this concept of informed refusal is well established in both the medical and behavioral health literature as well as in the law.

The answer to the question of how much understanding a patient must exhibit to be considered "informed" is less clear, however. For behavioral health patients who have concomitant, serious medical illness, the answer is often especially murky.

As Jeffrey P. Spike, PhD, and I recently discussed in an article in The Primary Care Companion, our experience is that psychiatrists and adult medicine physicians often assess patient capacity regarding the refusal of care in very different ways.

The 3 cases we presented in our article highlighted the tendency of psychiatrists to give patients the freedom to refuse care even if they do not express a full understanding of the details of their illness—provided that they do exhibit a basic understanding and have plans for meeting basic needs.

Adult medicine physicians, on the other hand, are inclined to require patients to state a more complete understanding of their illness and the consequences of refusing care, especially when that refusal might result in a serious, adverse medical outcome.

We believe this difference in assessing capacity is a reflection of psychiatric and adult medicine physicians' different experiences of the health care world. Because psychiatrists frequently interact with the legal system in competency hearings, because most behavioral illness is chronic and fluctuates over time, and because the physiologic consequences of psychiatric illness are rarely irreversible (beyond acute suicidal or homicidal behavior), psychiatrists are generally reluctant to remove decision-making power from patients. While the process of psychiatric consultation often facilitates patients’ ability to understand their illness in a general way—especially regarding social consequences—asking psychiatrists to specifically evaluate medical illness decision-making capacity is often frustrating, as their frame of reference is the mental health system and the courts.

In contrast, because adult medicine physicians face acute medical problems that do not fluctuate but frequently deteriorate without treatment, they are generally reluctant to allow patients to suffer the ill effects of what they perceive to be harmful, irreversible medical decisions. While adult medicine physicians are taught to beware of paternalism, asking them to respect psychiatric patients’ self-determination is often frustrating, as their frame of reference is the intensive care unit and the morgue.

When a strong difference of professional opinion occurs among the clinicians caring for a psychiatric patient with serious medical illness, we recommend two interventions. First, we encourage engaging both the patient's primary medical care clinician and primary behavioral clinician for input; hopefully, they have relationships and history with the patient and can provide context to help resolve these situations. Second, we strongly encourage obtaining formal ethics consultation, integrating both the psychiatric and hospital medicine approaches to assessing capacity—which we outline in our article—in order to find an empathic and pragmatic solution to these cases of refusal of care.

The Search for a Single-Nutrient Solution to Mental Illnesses Is Outdated

Our previous blog entry showed that the knowledge that good nutrition is essential for mental health is very old. Here, we would like to talk about the misguided approach taken by many scientists over the last century of looking for a single nutrient that will have profound effects on brain function.

Two reviews we have conducted of the scientific literature on the use of vitamins and minerals for the treatment of mood disorders and ADHD found dozens of reports from about 1910 to the present. Many nutrients have been studied, including the B vitamins; vitamins C, D, and E; and calcium, chromium, iron, magnesium, zinc, selenium, choline. But scientists were not studying nutrition in the way in which humans have evolved to require nutrients, ie, consumed together and in balance. Studies generally followed a “drug trial model” by giving patients a single nutrient and seeing if their symptoms improved.

Experimental science has made great progress by adhering to the principle that only one variable can be altered at a time and all other variables must be controlled. This approach aided the post–World War II golden era of drug development. A few decades ago, though, psychologists demonstrated the value of complex independent variables, investigating multivariable, usually manualized, treatments such as cognitive-behavioral therapy. The two of us thought this debate was over and that, especially in the realm of nutrition, multivariable treatments were accepted. But one of Julia’s manuscripts on multinutrient treatment was rejected recently by a leading American psychiatry journal with one reviewer complaining, “We can’t tell which is the active ingredient.”

Has the single-nutrient, “magic bullet” approach to mental illness yielded benefits? Yes, but the benefits are consistently modest. Calcium supplementation modestly improves mood; zinc or copper supplementation modestly improves mood and can improve attention; and various B vitamins administered singly modestly improve mood. Some recent research suggests that omega-3s or vitamin D administered in isolation can improve some psychiatric symptoms to a modest degree.

We acknowledge that for some physical illnesses, single nutrients can mean life or death. Scurvy is a great example of this because vitamin C can prevent and cure it. Pellagra and its psychosis can be cured with niacin therapy (more on that in our next blog entry). Also, vitamin B12 can completely eradicate pernicious anemia, an illness that often presents with psychiatric symptoms. And, what woman in the Western world who is planning a pregnancy is unaware of the need to take folic acid to prevent birth defects, although other B vitamins have also been shown to be beneficial?

What is troubling about the single-nutrient literature is that hundreds of studies and millions of research dollars have been wrongly based on the idea that a treatment must consist of just one nutrient at a time. The esteemed nutrition researcher Walter Mertz understood the fallacy in this way of thinking. Twenty years ago, he declared that all of the single-nutrient–related diseases had most likely been identified and that all future discoveries of health-related nutrition would consist of complex nutrient formulas. In the last decade or so, studies of broad spectrum or complex nutrient treatments have been conducted. We hope our future blog entries will convince you that broad-based nutrient supplementation is the most logical treatment of illnesses such as dysregulated mood, obsessions, impulsivity, hallucinations, and scattered attention, to name a few.

Can We Reduce School Shootings by Better Understanding Boys’ Brains?

As mental health professionals, we need to be acutely aware of a troubling phenomenon: the disenfranchisement of young boys in our homes and schools. This phenomenon has been occurring over the past several decades, often producing confused and violent boys and young men. At their earliest, formative ages, young boys’ behavior is being condemned by society. Some boys are reaching their teenage and young adult years confused about their identity and appropriate social norms.

The result? A steady spate of young males committing gun violence at Marysville Pilchuck High School‬ in Washington, UC Santa Barbara, Seattle Pacific University, Reynolds High School in Oregon, Sandy Hook Elementary in Connecticut, and elsewhere.

How did we get here?

In my recent book Raising Boys by Design, co-authored with brain science expert Michael Gurian, we noted a cultural trend to label boys as morally defective, hyper, undisciplined, or ‘problem children’ when frequently the problem is not the boys but the family, schools, and institutions that do not understand their brain chemistry and specific needs. Condemning their actions during early developmental years sends boys the message that their identity is something to be ashamed of. The resulting behavior can be shocking. Note these worrisome statistics:

  • Boys are diagnosed with learning disabilities at almost triple the rate of girls
  • Boys are almost twice as likely to repeat kindergarten as girls and more than twice as likely to be suspended
  • Boys receive 67% of the D’s and F’s given in school
  • Three times as many boys are considered mentally disabled compared to girls
  • 67% of all children held back in class are boys
  • 73% of children diagnosed with learning disabilities are boys
  • 81% of suicides among those aged 10–19 years are males
  • 80% of diagnosed behavioral disorders are in boys
  • 80% of children taking Ritalin are boys
  • 89% of incarcerated youths aged 15–17 years are boys

With more testosterone and less emotive brains than girls, boys express themselves much more physically than girls, especially at younger ages. It is absolutely natural, healthy, and necessary for young boys to expend their energy and emotions through physical activity.

Yet today, we have created a culture where normal behavior by boys is often instantly labeled as unruly and unacceptable. Throw in social media, technology addictions, and continued shortages of male mentors for young boys, and more problems arise.

So, what can we do?

We need to get brain research material to, and engage in conversations with, all adults who raise, teach, and care for young boys. Understanding the physiology of a boy’s brain and what stimulates it and allows it to be engaged and focused is essential.

Simple changes in environment to allow boys the physical outlet they need to focus can make a huge difference. For teachers, punishing a young boy by removing recess can be counterproductive, as physical activity is a key component in his brain development. Allowing a boy to sit on a large ball in the classroom, subtly bouncing, instead of on a chair, provides stimulation to engage his brain and help him better focus on the teacher. For parents, talking to your son while playing catch or taking a walk will enable him to focus much better than having him sit still at a table for a 15–minute discussion.

It is not easy to teach and raise young boys. I know, as I have 2 young boys myself. It can be difficult to know what is healthy, normal behavior and what crosses the line into aggression or even violence. But we need to figure it out and recognize that what we are doing today is not working. For the future of our young boys and all of us, we need to make understanding boys a priority.
