Pilot mental health: screening, privacy and care

A 41-year-old copilot arrives for the periodic medical examination required by the profession. He answers questions quickly and says everything is fine. During the conversation, he mentions almost in passing that he has been sleeping poorly for months, that he has been using a sleep medication bought without a prescription, and that he separated in the last year. When the doctor asks how his mood is, he smiles and changes the subject. At the end, he asks if what he says there "goes on the record." The scene is fictional and was written for teaching.

This text uses the picture as a clinical reasoning scenario: what studies say about depression in pilots, why so many avoid seeking help, how to screen for symptoms, what enters the differential, and which care pathways the sources describe. The text does not replace medical evaluation, is not a summary of any country's certification rules, and does not provide a treatment plan, because the sources read do not define one for pilots. If you play the case of the day on NEXO, you will recognize the challenge: the clues are there, but the person has reasons to hide them.

If you are going through a difficult time or thinking about taking your own life, reach out now to someone you trust, a health service, or a local emergency service, and seek the help you need. Asking for help is a step of care.

Key points

• Symptoms of depression appear in pilots at proportions described in various studies.
• Many pilots avoid seeking care for fear of losing their license.
• Screening with a brief questionnaire helps open the conversation.
• Peer support and non-punitive policies appear as facilitators of care.
• Talking about the topic with careful language is part of prevention.

Why pilot mental health is a reasoning scenario

The scenario combines a common condition, a profession with safety requirements, and a strong incentive to hide symptoms. The review by Pasha and Stokes gathered 20 studies and found a prevalence of depression in pilots from 1.9 to 12.6 per 100, with the caveat that most studies are cross-sectional (Pasha and Stokes, 2018). The authors also point out that pilots may report fewer symptoms than they have.

For those providing care, the difficulty is not in recognizing depression from a textbook. It is in noticing the signs in a consultation where the person has reasons to appear fine. The post on signs, symptoms and history shows how small clues change the reasoning.

What the scene teaches

The scene has five clues. The first is poor sleep for months. The second is the sleep medication without a prescription. The third is the recent separation, a negative life event. The fourth is the change of subject when mood enters the conversation. The fifth is the question about the record, which shows fear of consequences. None of them closes a diagnosis, but together they call for a more attentive conversation.

What the studies show

Wu and colleagues conducted an anonymous internet survey with pilots from various companies. Among those who responded to the depression questionnaire, 12.6 per 100 had scores compatible with depression, and 4.1 per 100 reported thoughts of death in the previous two weeks (Wu and colleagues, 2016). The authors found a relationship between symptoms and the use of sleep medications and the experience of workplace harassment, and noted that many pilots feared the impact of a diagnosis on their career.

O'Hagan and colleagues studied short-haul pilots and found that those with longer weekly duty periods had twice the chance of reporting symptoms of depression or anxiety (O'Hagan and colleagues, 2017). In France, Percheron and colleagues found anxiety symptoms in 25.4 per 100 pilots and depressive symptoms in 13.1 per 100 (Percheron and colleagues, 2025).

What these numbers allow us to say

These studies use questionnaires, and many rely on voluntary participation. They show that the symptoms exist and are not rare, but they do not give the exact prevalence and do not prove cause. Pasha and Stokes call for better studies, with follow-up over time (Pasha and Stokes, 2018). The post about base rate in diagnosis helps to understand why knowing the frequency of a condition changes the examiner's attention.

Pathophysiology: what the sources say and what they do not say

The sources read do not describe a biological mechanism specific to depression in pilots, and so this post does not describe one. What they describe are factors associated with work and life. Wu and colleagues found a relationship with the use of sleep medication and with harassment (Wu and colleagues, 2016). O'Hagan and colleagues found a relationship with workload (O'Hagan and colleagues, 2017).

Mulder and de Rooy highlight the role of negative life events, such as separation, losses and problems at work, and suggest that asking about them can serve as a screening tool (Mulder and de Rooy, 2018). In the scene, the recent separation is exactly that kind of event.

Sleep, routine and mood

The copilot's poor sleep deserves attention for two reasons. It can be a symptom of a mood condition and it can also be a factor that worsens the condition. The use of sleep medication without follow-up was one of the variables associated with symptoms in the study by Wu and colleagues (Wu and colleagues, 2016). The sources read do not allow us to say which came first, and this limit should be stated to the patient.

Why so many pilots avoid seeking help

Hoffman and colleagues surveyed pilots in the United States and found that 56.1 in 100 reported having avoided some health care for fear of losing their medical certificate (Hoffman and colleagues, 2022). In the same study, 45.7 in 100 reported having sought informal care or care outside the usual channels, and 26.8 in 100 reported having withheld information from the examiner (Hoffman and colleagues, 2022).

The comparison between countries showed a similar pattern. Hoffman and colleagues found avoidance of care in 56 in 100 pilots in the United States and in 55 in 100 pilots in Canada (Hoffman and colleagues, 2023). Fear, therefore, does not seem to depend on a single system.

Barriers described

Minoretti's review organizes the barriers to care into three main groups: stigma, fear of consequences for certification and lack of trust in confidentiality (Minoretti, 2025). In the scene, the question "does this go in the record?" touches directly on the third barrier. Answering honestly about what is recorded and what is not, according to the rules of the setting, is part of care.

Screening: how to open the conversation

The Aerospace Medical Association working group concluded that an extensive routine psychiatric assessment for all pilots would not be productive. The group recommended more attention from examiners to mental health aspects, education on the subject and support programs (Aerospace Medical Association, 2012).

A brief questionnaire can help open the conversation. Kroenke and colleagues validated the PHQ-9, a nine-question questionnaire about the last two weeks. Scores of 5, 10, 15 and 20 mark mild, moderate, moderately severe and severe depression, and a score of 10 or more had a sensitivity and specificity of 88 in 100 for major depression (Kroenke and colleagues, 2001).

The limit of the questionnaire

A questionnaire depends on the honesty of the person answering. If the person fears consequences, they may answer below what they feel. Hoffman and colleagues showed that withholding information from the examiner is not rare (Hoffman and colleagues, 2022). Therefore, the questionnaire is an entry point, not a verdict. The conversation and the relationship of trust remain at the center of the assessment.

Asking about thoughts of death

The PHQ-9 includes a question about thoughts of death or of hurting oneself (Kroenke et al., 2001). Asking about this directly and calmly is part of the assessment. The sources read do not define a risk assessment protocol for pilots, and so this post does not describe one. When the answer indicates intense distress, the path is to seek specialized assessment and immediate support, according to the services available in each place.

A possible conversation, step by step

One way to organize the consultation is to start with what the copilot himself brought up. He mentioned sleep, so the doctor can ask how long he has been sleeping badly, how it affects his day and what he has already tried. From there the conversation can move to the over-the-counter medicine, with curiosity and without a scolding tone. Then comes the separation: how he is dealing with it, who is nearby and whether there are other changes in his life.

Only then does the conversation reach mood, and by that point the question sounds like a natural continuation, not a test. The doctor can say that many people in similar situations go through periods of sadness or low spirits and ask whether this has been happening to him. If there is room, the questionnaire comes in as support, presented with clarity about what it is for.

This order is not a rule from the sources read. It is a way of applying what they describe: paying more attention to mental health in the examination, asking about life events and building trust (Aerospace Medical Association, 2012; Mulder and de Rooy, 2018).

The differential diagnosis

The sources read about pilots do not provide a formal list of differential diagnoses, and this post does not invent one. What they allow is to point out conditions that appear alongside depression in the same studies. Percheron et al. found anxiety symptoms in a significant share of pilots (Percheron et al., 2025). The same study found problematic alcohol use in 40.1 out of every 100 pilots who responded (Percheron et al., 2025).

In the scene, the doctor can therefore ask about anxiety, about alcohol and about the sleep medicine, as well as asking about mood. Each of these answers changes the reasoning and the referral. The post about differential diagnosis shows how to keep several hypotheses open.

Fatigue, sadness or depression

Bad sleep and tiredness can lead one to think only of work fatigue. Sadness after a separation can seem an expected reaction. Both readings can be right, but they can also hide a picture of depression. The PHQ-9 helps measure the intensity and duration of symptoms (Kroenke et al., 2001). The post about burnout in medical school discusses how exhaustion and depression come close.

Care and referral

The sources read do not define a medication treatment plan for pilots, nor doses, and so this post includes none. What they describe are paths for the pilot to reach care. The review by Minoretti points to peer support, non-punitive policies and access to independent and confidential care as facilitators (Minoretti, 2025).

Pinsky et al. discuss the psychiatrist's role on the topic and argue for forms of support for pilots who are afraid to reveal symptoms, including peer support networks (Pinsky et al., 2020). Hoffman et al. proposed a regulatory framework that seeks to balance safety and access to treatment (Hoffman et al., 2024).

Peer support

Mulder and de Rooy describe peer support programs and a just culture, in which reporting a problem does not automatically lead to punishment. The programs were well rated by pilots, but the authors note that a protective effect has not yet been demonstrated (Mulder and de Rooy, 2018). This care in interpretation is important: the idea is promising, and the evidence is still being built.

What to say to the copilot

In the scene, the doctor can recognize poor sleep and the separation as difficult experiences, ask calmly about mood and explain, honestly, what happens to the information from the consultation according to the rules of the place. She can also talk about the support options available, including peer programs where they exist, and arrange a follow-up. The rules on being signed off from flying and returning to flying vary between countries, and the sources read do not allow them to be summarized here.

The follow-up

The follow-up is part of the care, not an administrative detail. It shows the co-pilot that the conversation did not end with a stamp and gives the doctor the chance to see how the symptoms have evolved. If the first meeting opened only a crack, the second can go deeper. If the co-pilot accepted a referral, the follow-up shows whether he managed to get to the service and what he thought of it.

The sources read do not define the ideal interval for this follow-up or a script for it. What can be said is that trust is built over time, and that the relationship with the person providing care is one of the conditions described for the pilot to seek help (Minoretti, 2025).

Confidentiality, safety and trust

The topic involves two values that seem to compete: flight safety and the pilot's right to care. The sources read suggest that treating the two as opposites tends to keep pilots away from care. Hoffman and colleagues showed that the fear of losing the license leads many to avoid or hide health problems (Hoffman and colleagues, 2022). Minoretti describes trust in confidentiality as one of the conditions for care to happen (Minoretti, 2025).

For those providing care, this means that the form of the consultation matters. A conversation in which the pilot feels judged can end the subject. A conversation in which he understands what will be done with the information and feels that there is a possible path tends to open space for the truth. The post about empathy and clinical reasoning shows how listening changes the quality of the information.

The role of the examiner

The Aerospace Medical Association working group recommended that examiners pay more attention to mental health during the examination and receive training on the topic (Aerospace Medical Association, 2012). This includes asking about life events, sleep, alcohol and mood, and not merely following a script. In the scene, the doctor did exactly that when she noticed the change of subject.

How to talk about the topic with care

Mishara and Dargis compared recommendations for safe communication about suicide and found points in common: do not describe methods, avoid presenting suicide as a solution, encourage seeking help and inform where to find it (Mishara and Dargis, 2019). This text follows these recommendations and avoids details of reported cases.

In the consultation, the same logic applies. Talking about suffering calmly, without sensationalism, and making clear that help exists are forms of care. For the team that teaches, discussing the topic with fictional cases allows the conversation to be practiced without exposing anyone. Care with the choice of words also matters: terms that sound like judgment, or that treat suffering as weakness, tend to close the conversation. Simple sentences that acknowledge the difficulty and show that there is a path usually open space. The same applies to teaching materials, posters and corridor conversations between colleagues.

Colleagues and people close to them

Often the first person to notice the change is a cabin colleague, a friend or a family member. The sources read do not provide a guide for these people, but they describe the importance of peer support networks (Pinsky and colleagues, 2020). A simple conversation, in private and without judgment, can be the first step for someone to seek help.

Teaching the topic in the classroom

For those who teach, the scenario offers a rare opportunity: to train a consultation in which the patient has reasons to hide symptoms. Discussing the fictional case allows practice of the order of the questions, the explanation about confidentiality and the way of talking about thoughts of death. It also allows discussion of the discomfort of the person providing care in the face of the topic, which helps to avoid both silence and excessive alarm.

Reasoning: when the person seems fine

The biggest risk of error in this scene is accepting the "everything is fine" and ending the consultation. Croskerry describes premature closure as the tendency to end reasoning before considering all the clues (Croskerry, 2003). Here, poor sleep, the sleep medication, the separation and the change of subject are clues that call for one more question.

The other error is the opposite: turning every sign of tiredness into a psychiatric diagnosis. The balance comes from asking, measuring with a validated instrument and talking. The post about diagnostic pause shows how to stop before closing the case, and the post about affective bias discusses how the doctor's own emotions enter the reasoning.

Case summary in a table

Changes the subject about mood	Possible concealment	Omitting information is not rare (Hoffman)
Question about the form	Fear of consequences	Trust in confidentiality is a central barrier (Minoretti)
Screening	Brief questionnaire	Validated PHQ-9 (Kroenke)
Care	Support and referral	Peers and confidential care as facilitators (Minoretti)

How NEXO helps train this reasoning

To use the case of the day as training, try three habits. Before each guess, ask what clue the person might be hiding. When the story seems calm, look for the detail that does not fit. After the result, note whether you ended the reasoning early.

Three exercises with cases

List the discreet clues. Write down the clues that appeared in passing and what each one may mean.

Keep two hypotheses. Before concluding, write one simple explanation and one more serious explanation for the same symptoms.

Think about the conversation. Write how you would ask the next question in a way that makes the person feel safe to answer.

The post about learning based on clinical cases shows how cases help fix this habit.

The limits on using the game are described on the NEXO economy page. If you research teaching of clinical reasoning, the page for researchers explains how to get in touch. Professionals who write or review cases find information on curation and on creators, and institutions can learn about the proposal on the for partnerships page.
