Mental Health and Suicide Loss: What the Research Actually Shows

May arrives every year, and somewhere in the back of my mind I still think about those four months. Our son John was diagnosed with bipolar disorder in the later winter of 2008. He was 17. He was a football player, a second-degree Taekwondo black belt, and the kind of person who could fill a room with his warmth, without even trying. The diagnosis felt wrong in the way that only the worst surprises do.

Less than four months after that diagnosis, we lost him to suicide.

Every year, May is Mental Health Awareness Month. And the connection between mental health and suicide loss runs deeper than many survivors realize at first. Not everyone who lost someone to suicide knew their person had a mental health condition. Some did. Some didn’t. Some are still asking that question years later. The discussion in this post can feel clarifying or devastating depending on where you are in your grief.

I want to walk through this data about mental health with you. Not to reduce the person you lost to a clinical category or statistic. Not to wrap the loss in a tidy explanation. But because understanding what was happening beneath the surface, the pain that often goes unseen and untreated, can be part of finding solid ground.

And because the stigma around mental health and the stigma around suicide are first cousins. They keep the same silences. Breaking one of them starts by being willing to look closely at them.

The 90 Percent: What Mental Health and Suicide Loss Research Reveals

Research gathered through what are called psychological autopsies, detailed reviews conducted after a suicide death that reconstruct a person’s mental and emotional state from records, interviews, and history, suggests that:

That finding comes from more than 30 studies conducted around the world and is consistently cited by the American Foundation for Suicide Prevention.

That number sometimes stops survivors cold. You may have also read that only about 49 percent of people who die by suicide had a known, documented diagnosis in their medical records. Both figures are accurate. They describe different things.

The 49 percent reflects formal diagnoses already on the books. The 90 percent reflects what researchers found when they looked backward, carefully, at the full picture of a person’s inner life. Many people who die by suicide were never formally diagnosed. They had not sought treatment. Or they were living with conditions that were simply not on anyone’s radar, including their own.

The person you cared for may have been in that gap. Many people are.

There is also something important to carry alongside that statistic.

A diagnosis is, when you strip everything else away, a description of pain that has a name.

The Scale of Mental Health Struggles in America

The scale and the numbers are worth exploring, not to overwhelm, but to give context for how common these struggles are, and how often they are carried invisibly.

• Mental Health America reports that approximately 22.5 million U.S. adults currently live with major depression. Another 3.3 million live with bipolar disorder. More than 46 million Americans have a substance use disorder. The lifetime prevalence of any anxiety disorder is 31.6 percent, making anxiety conditions the most common category of mental illness in the country.
• NAMI’s national data shows that in any given year, anxiety disorders affect 19.1 percent of U.S. adults. Major depressive disorder affects 15.5 percent. PTSD affects 4.1 percent. Bipolar disorder, though less prevalent at around 2.8 percent annually, carries one of the highest suicide risks of any diagnosis.

These are not small numbers. Tens of millions of people. And because mental health struggles carry stigma, a significant share of them are never discussed, never treated, and never seen by the people closest to the person carrying them.

This is the same stigma that wraps around suicide. It is not a coincidence that the two tend to go unspoken together. Both get hidden. Both get minimized. Both leave survivors in the dark long after the death.

A Diagnosis Is Not a Death Sentence

If the person you lost had a mental health diagnosis, please don’t skip this section.

A diagnosis does not mean the death was inevitable. Mental health conditions are real. They are serious. They carry measurable risks. But they are also treatable. They are manageable. Millions of people live full, meaningful lives with bipolar disorder, schizophrenia, depression, and anxiety.

John had bipolar disorder. That diagnosis does not explain what happened to him. It is part of his context. It is not the cause that makes his death make sense. It does not define him. It does not define us.

The research on suicide consistently points to something more complex than diagnosis alone. A diagnosis can increase vulnerability. It can narrow a person’s capacity to think clearly during a crisis. It can make ordinary pain feel unbearable in ways that people outside the experience simply cannot see. But it does not determine the outcome. Treatment works. Connection works. Early intervention works.

I’ve heard this fear expressed in many ways around the room at our suicide loss support group SOS Madison over the past seventeen-plus years. “Did their illness make this inevitable?” The answer is no. The illness increased risk. The death itself was the result of far more than a label in a chart.

Understanding that gap, between a diagnosis and what ultimately happens, is part of understanding what your person was carrying.

Mental Health Conditions and Suicide Risk: What the Data Shows

Knowing how individual conditions relate to suicide risk matters for survivors trying to understand what their person may have been experiencing. This is not about assigning cause. It is about context.

A major study published in Psychiatric Services, drawing on records from more than 267,000 patients across eight health care systems, found the following elevated risks of suicide death compared to people with no mental health diagnosis:

• Schizophrenia spectrum disorders showed the highest adjusted odds ratio at 15.0. Patients with this diagnosis had roughly 15 times the odds of dying by suicide compared to people without a diagnosis. The elevated risk is driven in part by the severe cognitive disruption these disorders cause, including paranoid thinking that can make the world feel profoundly threatening and escape feel like the only option.
• Bipolar disorder came in second, with an adjusted odds ratio of 13.2. The risk is particularly high during mixed states, when depression and agitation occur simultaneously. Bipolar disorder may carry the highest rate of suicide attempts of any diagnosis, and the illness can make danger arrive suddenly, even for people who have been stable for extended periods.
• Depressive disorders showed an adjusted odds ratio of 7.2. Depression is the most common condition associated with suicide deaths, and it is also one of the most frequently missed. The “why” question that haunts so many survivors often circles back here. Why didn’t I see it? Because depression, especially in people who are high-functioning by outward appearances, can be nearly invisible to the people who care for them most.
• Anxiety disorders showed an adjusted odds ratio of 5.8. Anxiety is often treated as a lesser concern, as worry rather than illness. But the data tells a different story. Chronic anxiety, particularly panic disorder and untreated PTSD, can make a person’s internal world feel relentlessly unsafe. That is not a small thing to live with.
• ADHD showed an adjusted odds ratio of 2.4, the lowest on this list. Importantly, research suggests that much of ADHD’s connection to suicide risk runs through comorbidity. When ADHD occurs alongside depression or substance use disorder, the risk increases substantially.
• A meta-review published in World Psychiatry, covering data from more than 1.7 million patients across 20 different disorders, also identified borderline personality disorder and anorexia nervosa among the conditions with the highest suicide risk.

Substance use disorders, both alone and as co-occurring conditions, dramatically amplify risk across every category.

The word that appears again and again in this research is “comorbidity.” When more than one condition is present, the risks compound. And in many people, several conditions are present at once, often without the person or anyone around them fully knowing.

If you are reading this and wondering whether the person you cared for was struggling with something that was never diagnosed or fully understood, you are asking a real question.

Many other suicide loss survivors are also struggling with that question.

When the Illness Hides Itself

One of the hardest things for some survivors to sit with is this: the person they lost may have genuinely not known they were as sick as they were.

This is not a figure of speech. There is a condition, more common than most people realize, where the illness itself damages the part of the brain responsible for self-awareness. Not partially. Sometimes completely. A person with schizophrenia or bipolar disorder can be in the grip of something severe and have no internal signal telling them anything is wrong. They do not feel sick. They feel like themselves. What looks like refusal from the outside is, from the inside, simply reality as they experience it.

NAMI describes this as anosognosia, a word that comes from Greek meaning “to not know a disease.” It is not denial. A person in denial can sometimes be reached by evidence or by someone they trust. A person with anosognosia cannot, because the part of the brain that would receive that message is not functioning normally. Research estimates it affects roughly 40 percent of people with bipolar disorder and up to 50 percent of people with schizophrenia to some degree.

I remember sitting with our son John in his psychiatrist’s office not long after the diagnosis. John was certain there was nothing wrong with him. The doctor handed him a copy of Kay Redfield Jamison’s memoir An Unquiet Mind, the account of a psychologist who lived with bipolar disorder. John did what most 17 year-olds assigned a book would do. He highlighted passages. He stuck Post-it notes on pages. At first he could not find himself in it at all. Over the course of the next week, he came back and reluctantly said he understood why we thought he had bipolar. But he still could not quite believe it was true for him.

That is anosognosia. Not defiance. Not denial. A brain that genuinely could not close the distance between what we saw and what he felt.

This is why some people stop taking medication when it starts working. They feel better. And because they feel better, they conclude they do not need it. This cycle, stable for a while, then destabilized, then slowly finding stability again, is familiar to many families who cared for someone with one of these conditions.

If you ever asked yourself why the person you cared for would not get help, or would not stay in treatment, or seemed not to understand how much they were struggling, this may be part of the answer. Not stubbornness. Not not caring. The illness itself blocked the door.

That is not a small thing to carry. It is also, for many survivors, one of the most relieving things they have ever learned.

No Single Cause: How Multiple Things Converge

Survivors often search for the one thing. The one phone call they did not make. The one appointment that was missed. The one moment that, if it had gone differently, might have changed everything.

Researchers who study suicide understand that search. They also understand why a single explanation almost always falls short.

Think of it this way. A mental health condition may have been present for years. Stress may have been building for months. Something may have happened in the days or hours before the death. Access to a means of self-harm may have been part of the picture. Protective factors that might have interrupted the crisis, a person nearby, a connection to treatment, a reason to hold on, may have been absent or worn thin.

A stress-vulnerability framework, which researchers have used for decades to study suicide, holds that the vulnerability alone does not produce the outcome. The stressor alone does not produce it. The crisis alone does not produce it. What produces it is the convergence of several things at once in a person who had been carrying more than most people around them could see.

This matters for survivors because it means no single failure point explains what happened. Not yours. Not your person’s. Not the doctor’s or the system’s, though systems do fail people and that is real. The death was not caused by the one thing you keep returning to. It was the result of a terrible alignment of many things, most of them invisible to everyone around the person, and some of them invisible even to the person themselves.

A perfect storm, people sometimes call it. But there was nothing perfect about it. It took someone.

That does not make it easier to hold. But it is more accurate. And accuracy, for many survivors, is part of what allows them to stop circling the same moment forever. Eventually, many survivors lock on to a story that is nuanced.

If There Was a Prior Attempt

Some survivors knew about a prior attempt. Some did not. Either way, this section is important to understand.

That is a sentence an important one to try and process, because it can land two different ways depending on where you are in your grief.

• If you knew about a prior attempt, you may be asking whether you did enough with that information.
• If you did not know, you may be stunned to learn it was there.

Both responses make sense.

The research adds something important alongside that statistic. According to a major review published by Harvard’s T.H. Chan School of Public Health, approximately 9 out of 10 people who survive a suicide attempt do not go on to die by suicide. Roughly 7 percent of attempters eventually die by suicide, with most estimates ranging from 5 to 11 percent depending on the study and the follow-up period.

The Suicide Prevention Resource Center adds that approximately 60 percent of people who died by suicide did so on what was their first attempt, meaning about 40 percent had a prior attempt that had been recorded.

Two things are both true at the same time. A prior attempt signals serious risk and warrants serious attention. And the large majority of people who make an attempt go on to survive. Neither fact cancels the other out.

For survivors, this can feel like an unsolvable paradox. If it is such a strong predictor, why did treatment not do more? Why was it not enough to change what happened? These are not questions with clean answers. What the research does say is that the transition period after an attempt, particularly the first year, carries elevated risk, and that follow-through with treatment during that window matters enormously. Many people fall through the gaps during exactly that period.

If you knew about a prior attempt and poured everything you had into trying to help your person, that is not a failure. If you did not know, the fact that you could not see what was not shown to you is not a failure either.

What Was Happening in the Final Days and Hours

This is the a more technical section. But it has some hard truths in it.

The clinical frameworks researchers have developed for understanding this period are among the most important things a survivor can encounter.

Psychache is a concept developed by psychologist Edwin Shneidman. It describes an unbearable psychological pain, one that goes beyond sadness or depression and becomes something a person believes they simply cannot survive. Shneidman’s central argument was that suicide is not about wanting to die. It is about wanting to escape a pain that feels inescapable. The person in psychache is not thinking clearly about forever. They are experiencing something that has overwhelmed their capacity to see any other way through.

Suicide Crisis Syndrome is a more recently described state that researchers are proposing as a distinct clinical diagnosis to capture what happens immediately before a suicidal act. Research published in Frontiers in Psychiatry describes it as an acute state of cognitive and emotional dysregulation that can develop within hours or days before a suicidal act. Its core features are a desperate, frantic feeling of hopelessness and entrapment, accompanied by loss of cognitive control, extreme arousal, and withdrawal. Critically, research has found that:

The crisis can escalate rapidly, and it often does not look like what those around the person imagine crisis to look like.

Suicidal trance is a related concept describing the narrowing of thinking that can occur as a crisis deepens. A person in this state is not thinking broadly. The normal capacity to weigh options, imagine tomorrow, or find a way through has narrowed down to a tunnel. They are not making a reasoned, deliberate decision. They are trapped in a mental state that has stripped away much of what ordinarily allows people to survive unbearable moments. This is part of why the question of whether suicide was a choice is so much more complicated than it sounds.

None of this makes the suicide loss easier to hold. But it begins to answer the question that lives inside the hearts and minds of so many survivors:

Breaking the Silence Around Mental Health and Suicide Loss

Mental health stigma and suicide stigma share the same roots.

People do not talk about their depression because they worry about being seen as weak. People do not talk about a family member’s bipolar disorder because they fear judgment. And when someone dies by suicide, the grief is often carried in silence because suicide itself is still treated as something shameful, something to be hidden or explained away.

And, pardon my language, that sucks.

Kevin Breel, a comedian who nearly died by suicide at 19, put the stigma plainly in his TED talk: break your arm and everyone signs your cast. Tell people you’re depressed and everyone runs the other way. The difference between those two things is the stigma.

If you are a survivor, you have likely felt both kinds of stigma. The one that surrounds the death. And the unspoken hesitation to talk about whatever mental health struggles your person may have been carrying. Sometimes those two layers of silence compound each other until a survivor is carrying something enormous, completely alone.

Reading the data in this post does not make you disloyal to the person whom you lost. Understanding what was happening inside the person you cared for is not clinical detachment. For many survivors, it is a form of love. It is saying:

That is not guilt. That is the search for understanding that most survivors share.

I hear it around the room at our support group in nearly every meeting. The questions about what was really happening. The need to understand the brain and the pain of someone who is gone. That wanting is real. It is also good. It means you are still paying attention to someone who mattered.

If the data in this post is part of that search for you, you are in the right place. Peer support, whether in a group or through connection with other survivors, can hold the weight of questions like these alongside you. There is no judgement at a support group. We are all struggling for answers. The questions do not always have clean answers. But carrying them with other people who understand suicide loss makes them more bearable.

May is Mental Health Awareness Month. It is also the month I carry John’s diagnosis in the back of my mind, the way I carry him everywhere, in the weight of what was known and what was not, in what could have been different and what could not.

His bipolar disorder was part of his story. It was not all of it. He was also a boy who said sunflowers were the happiest flower. He was a black belt and a football player and someone whose laugh could lighten an entire room full of people. The diagnosis was something that happened to him. The rest of who he was belonged entirely to John.

Mental health awareness does not mean reducing people to their diagnoses. It means being willing to see the pain that people carry when it is still possible to help.

For those of us surviving a loss, it means being willing to understand what that pain looked like, even after the fact, even from this side of it.

If you are carrying this pain right now, you are not alone in it. And there are people who understand what mental health and suicide loss leave behind.

We are here.

You are not alone.
