What Do Psychiatrists Do

Short answer

• A psychiatrist is a medical doctor who specializes in psychiatry, the branch of medicine focused on the diagnosis, treatment, and prevention of mental, emotional, and behavioral disorders. Psychiatrists assess both mental and physical aspects of a person's condition, make diagnoses, and develop treatment plans. Because they are physicians, they can order and interpret medical and psychological tests, prescribe medication, and provide other medical treatments. Many also provide psychotherapy, often called talk therapy, and they commonly work as part of a wider care team that may include psychologists, therapists, nurses, social workers, and primary care physicians. In short, a psychiatrist brings a medical perspective to mental health care, looking at symptoms, medical history, and life context together.

This article is general information about a profession. It is not medical advice, and it does not diagnose, treat, or recommend care for any individual. Anyone seeking care for a mental health concern should speak with a qualified health professional about their own situation.

What Is a Psychiatrist

A psychiatrist first trains as a physician, earning either a Doctor of Medicine degree, abbreviated MD, or a Doctor of Osteopathic Medicine degree, abbreviated DO, and then completes specialty training in psychiatry. That medical foundation is the central difference between a psychiatrist and most other mental health professionals. It means a psychiatrist is trained to consider whether a physical illness, a medication, a substance, or another medical condition could be contributing to a person’s symptoms, and to coordinate care with other physicians when needed.

Cleveland Clinic describes a psychiatrist as a medical doctor who is an expert in psychiatry, and notes that psychiatrists assess both the mental and physical aspects of psychological conditions. A first assessment typically covers far more than a list of symptoms. It may include medical history, family history, current medications and substances, sleep, appetite, energy, concentration, daily functioning, relationships, and work or school life. The goal is to understand the person in context, not to reduce a complex life to a single label.

Psychiatrists also use formal diagnostic criteria. In the United States, the standard reference is the Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychiatric Association and commonly called the DSM-5. A diagnosis is a clinical judgment based on an interview, history, examination findings, and test results where relevant, not a single score, and two people with the same diagnosis may have very different treatment plans.

Practice styles vary: some psychiatrists focus mainly on medication management alongside a separate therapist, others provide psychotherapy themselves, and others work mainly in hospitals, research, or teaching.

The Core Work: Assess, Diagnose, Plan, Treat, and Monitor

Most clinical psychiatry work follows a cycle: assessment, diagnosis, treatment planning, treatment, and ongoing monitoring.

Assessment is the information gathering phase, and it is usually the longest part of early contact. A psychiatrist will ask about current symptoms, when they started, how they have changed, and how they affect sleep, appetite, energy, concentration, work, school, relationships, and daily routines. A psychiatrist may also perform a physical examination or order laboratory tests, imaging, or psychological testing. Cleveland Clinic notes that psychiatrists can order or perform a variety of medical and psychological tests, and that these tests, combined with conversations about symptoms and medical and family history, allow them to diagnose mental health conditions. Tests are not used in isolation. A laboratory result might rule out a thyroid problem or another medical cause, and the psychiatrist interprets results alongside the interview, not instead of it. Assessment also routinely includes questions about thoughts of harming oneself or others, substance use, and supports at home, because those factors affect urgency and level of care.

Diagnosis means naming, as precisely as possible, the pattern that best fits a person’s symptoms, history, and examination findings, using accepted criteria such as those in the DSM-5. A careful diagnosis helps the psychiatrist and patient discuss what is known about a condition in general terms, guides which treatments are most likely to be considered, and helps other clinicians understand the picture quickly. At the same time, diagnosis is rarely instant or final. Symptoms can overlap between conditions and change over time, and new information from follow up visits or test results can refine an earlier impression.

After assessment and diagnosis, the psychiatrist works with the patient to form an individualized treatment plan. Cleveland Clinic stresses that treatment is very individualized and unique to each person, often involving a combination of approaches. A plan may include psychotherapy, medication, other medical treatments, support measures, referrals, or monitoring before active treatment begins. The balance depends on the condition, severity, patient preferences, medical history, previous responses, and practical factors such as access and cost. Plans are revised when treatment is not helping, side effects are troublesome, or circumstances change.

Medication management is the part of psychiatry most people associate with the role, but it is only one part. Psychiatrists can prescribe, monitor, adjust, change, and stop medications when appropriate. Cleveland Clinic lists classes typically prescribed, including antidepressants, antipsychotic medications, mood stabilizers, sedatives and anxiolytics, hypnotics, stimulants, and ketamine in specific clinical contexts. Each class works differently. In practice, management also involves checking interactions, including over the counter products and supplements, monitoring physical health measures where relevant, and reviewing side effects and symptom change. Specific advice for any individual always comes from that person’s own clinician.

Psychotherapy, often called talk therapy, involves talking with a trained mental health professional to identify and work through factors affecting mental health. Cleveland Clinic describes its goal as eliminating or controlling disabling or troubling thought and behavioral patterns so a person can function better, and notes that psychotherapy can be short term or long term. Common forms include cognitive behavioral therapy, interpersonal therapy, mindfulness based cognitive therapy, dialectical behavior therapy, problem solving therapy, and psychodynamic therapy. Some psychiatrists provide psychotherapy regularly. Others focus on assessment and medication management and refer to a colleague for psychotherapy, while staying in close communication with that colleague.

Follow up completes the cycle. Psychiatrists see patients again to review progress, adjust the plan, and address new concerns, and between visits they may communicate with a primary care physician, therapist, or hospital team, within privacy rules and usually with the patient’s knowledge. Like all physicians, they document their work in medical records, so care remains continuous.

Conditions Psychiatrists Commonly Work With

The following overview describes, in general terms, kinds of problems commonly within psychiatry. It is not a self diagnosis guide, and experiencing one symptom from a list does not mean a person has a particular condition.

Depressive disorders involve persistent low mood, loss of interest or pleasure, changes in sleep or appetite, low energy, and difficulty concentrating. Bipolar and related disorders involve episodes of elevated or irritable mood and increased energy alongside episodes of depression. Anxiety disorders involve excessive fear, worry, or avoidance that interferes with daily life, including generalized anxiety, panic disorder, and specific phobias. Obsessive compulsive and related disorders involve intrusive thoughts and repetitive behaviors a person feels driven to perform. Trauma and stressor related disorders, including post traumatic stress disorder, can follow exposure to traumatic events.

Schizophrenia spectrum and other psychotic disorders involve changes in thinking and perception, such as delusions or hallucinations, alongside difficulties with motivation, emotion, and daily functioning. Substance related and addictive disorders involve harmful use of alcohol or other drugs, often alongside other mental health conditions. Eating disorders involve disturbed eating behavior and attitudes toward weight and body shape that affect health. Sleep disorders, including insomnia, are also within psychiatric practice, particularly when they interact with mood or anxiety. Neurocognitive disorders, such as dementia related conditions, involve decline in memory, thinking, and daily functioning. Personality disorders involve enduring patterns of thinking, feeling, and behaving that cause distress or difficulty in relationships and work. Attention deficit hyperactivity disorder involves persistent patterns of inattention, hyperactivity, and impulsivity that interfere with functioning. Often the picture is a combination, such as depression alongside a chronic medical illness.

Treatments Psychiatrists Use

Psychiatrists draw on several broad approaches, often in combination. Psychotherapy is one. Cognitive behavioral therapy focuses on links between thoughts, feelings, and behaviors and on practical skills for changing unhelpful patterns. Interpersonal therapy focuses on relationships and life transitions. Dialectical behavior therapy combines skills training with support for emotion regulation. Psychodynamic therapy explores how past experiences shape present difficulties. A psychiatrist may provide one of these approaches or refer to a colleague who specializes in it.

Medication is a second approach, described above. Category names alone do not indicate what is appropriate for any person. That decision depends on diagnosis, medical history, other medications, preferences, and clinical judgment, and it belongs in a clinical relationship, not in an article.

A third category includes other medical treatments for certain conditions. Cleveland Clinic lists electroconvulsive therapy, abbreviated ECT, transcranial magnetic stimulation, abbreviated TMS, and light therapy for seasonal depression. ECT involves brief, controlled electrical stimulation of the brain under general anesthesia, generally reserved for specific severe conditions. TMS uses magnetic pulses applied to the scalp, without anesthesia, for certain depressive conditions. Light therapy involves regular exposure to bright light, typically in the morning, for seasonal patterns. These are specialized treatments, offered only in appropriate settings with detailed consent discussions, and are listed here to explain scope of practice, not as a suggestion for any individual.

Where Psychiatrists Work

The United States Bureau of Labor Statistics notes that physicians and surgeons work in clinical settings such as physicians’ offices and hospitals, and in nonclinical settings such as government agencies, nonprofit organizations, and insurance companies. Psychiatrists follow a similar pattern.

In private offices and group practices, a psychiatrist may see outpatients by appointment, manage an ongoing caseload, and collaborate with therapists and primary care physicians. Outpatient clinics, including community mental health centers, hospital based clinics, and veterans’ health services, serve people who live at home and attend regularly, often with team based care alongside nurses, social workers, psychologists, and peer specialists. In hospitals, psychiatrists work on inpatient psychiatric units, where people are admitted for intensive treatment, often during a crisis, and as consultation liaison psychiatrists in general hospitals, assessing patients admitted for medical problems who develop psychiatric symptoms. Emergency departments also involve psychiatrists, directly or through consultation.

Other settings include academic centers, government and public health roles, school and university services, residential programs, and telepsychiatry by video or phone, which has expanded rural access though licensing and privacy rules still apply. Schedules vary: the Bureau notes that most physicians work full time, some work more than 40 hours per week, and many work irregular, overnight, or on call hours, with hospital psychiatrists more likely to work nights and weekends.

How to Become a Psychiatrist

The usual route in the United States is described below. Routes in other countries differ in length, examinations, and titles.

First comes a bachelor’s degree. The Bureau of Labor Statistics notes that physicians typically need a bachelor’s degree as well as a medical degree, with no specific undergraduate degree required, though applicants usually have studied biology, physical science, or health care related fields. Aspiring psychiatrists usually complete premedical coursework, take the Medical College Admission Test, gain clinical or volunteer experience, and apply to medical schools, which the Bureau describes as highly competitive. Some schools offer combined programs lasting six to eight years.

Medical school typically takes four years, according to the Bureau of Labor Statistics. The first phase is largely classroom, small group, and laboratory based, covering anatomy, biochemistry, pharmacology, psychology, medical ethics, and the laws governing medicine, alongside skills in taking histories and examining patients. The second phase is clinical: students work with patients under supervision in hospitals and clinics, rotating through internal medicine, pediatrics, surgery, and psychiatry.

Graduates leave with an MD or a DO degree. Both are full medical degrees. The Bureau notes that both use the same methods of treatment, including drugs and surgery, while DO physicians place additional emphasis on the musculoskeletal system, preventive medicine, and whole person care. For psychiatry the distinction matters little: MD and DO psychiatrists complete the same specialty training and sit for the same board examinations.

After medical school, almost all graduates enter a residency in their specialty, according to the Bureau. Psychiatry residencies in the United States are commonly structured over four postgraduate years, with rotations across inpatient, outpatient, emergency, consultation liaison, child and adolescent, addiction, and geriatric psychiatry, and neurology and general medicine. Residents receive teaching in psychotherapy, psychopharmacology, neuroscience, and ethics, and carry outpatient caseloads under supervision in later years. All accredited programs share supervision: attending psychiatrists review assessments, discuss plans, and take ultimate responsibility for patient care during training.

Before independent practice, a physician must hold a medical license in the state or states where they practice. The American Board of Psychiatry and Neurology, abbreviated ABPN, states as a general requirement that physicians must have a valid, unexpired, and unrestricted license to practice medicine in at least one state, commonwealth, territory, or possession of the United States or province of Canada, and that if more than one license is held, all must be unrestricted. Licensing requirements are set by state medical boards, not by the ABPN. A license legally permits practice. Board certification is separate.

Board certification demonstrates specialty expertise beyond basic licensure, though many employers require or strongly prefer it. For psychiatrists, the certifying body is the ABPN. The ABPN states that to qualify to sit for examination, an applicant must possess a qualifying medical degree, complete training in an ACGME accredited or ABPN approved program, hold an active, full, unrestricted medical license as defined in its policies, and satisfactorily complete its specialized training requirements. Physicians who pass become ABPN diplomates, meaning board certified psychiatrists. Certification is not one time only. The ABPN operates a Continuing Certification Program covering professional standing, lifelong learning, and periodic assessment. For patients, board certification confirms accredited training and a passed specialty examination, but does not by itself guarantee a good personal fit.

Some psychiatrists then complete a fellowship, focused training in a subspecialty. The Bureau notes that subspecialization for physicians generally includes fellowship training of one to three years. ABPN subspecialty areas include child and adolescent psychiatry, addiction psychiatry, forensic psychiatry, geriatric psychiatry, and consultation liaison psychiatry, alongside areas such as clinical neurophysiology and sleep medicine that overlap with neurology. Child and adolescent psychiatrists work with young people and families, geriatric psychiatrists with older adults, forensic psychiatrists at the interface of psychiatry and the law, addiction psychiatrists on substance related disorders, and consultation liaison psychiatrists in general medical hospitals. Many general psychiatrists do not complete a fellowship and care for adults across a broad range of conditions.

Altogether, the usual route is a bachelor’s degree, four years of medical school, and a residency commonly lasting four years, plus optional fellowship of one to three years. A person entering college intending to become a psychiatrist should expect well over a decade of education and training before independent practice. That length also explains why workforce shortages correct slowly: expanding capacity takes years before new psychiatrists enter practice.

Psychiatrist vs Psychologist vs Therapist vs Other Professionals

Titles imply different training, legal powers, and roles. Rules vary by state and country, so the table below is a general guide, not a legal statement for any particular place.

Professional	Usual training	Can prescribe medication	Main focus
Psychiatrist	Medical degree (MD or DO) plus psychiatry residency	Yes, as a licensed physician	Diagnosis and medical treatment of mental, emotional, and behavioral disorders; some provide psychotherapy
Psychologist	Doctoral degree in psychology (PhD or PsyD), plus supervised practice	Generally no, with limited exceptions in a small number of states for those with additional specialized training	Psychological assessment and psychotherapy; many conduct research
Therapist or counselor	Usually a master’s degree in counseling, social work, marriage and family therapy, or a related field	No	Psychotherapy and counseling
Psychiatric mental health nurse practitioner	Nursing degree plus graduate training in psychiatric mental health nursing	Yes, within state scope rules, which vary	Assessment, diagnosis, psychotherapy, and medication management
Primary care physician	Medical degree plus residency in family medicine, internal medicine, or pediatrics	Yes, as a licensed physician	General medical care, including common mental health conditions, with referral for complex cases
Neurologist	Medical degree plus neurology residency	Yes, as a licensed physician	Disorders of the brain and nervous system, including the brain, spinal cord, and nerves

Psychologists are highly trained, and not prescribing does not make their work less important. They often provide intensive psychotherapy, conduct detailed testing psychiatrists may rely on, and lead research. Psychologists typically hold a doctoral degree in psychology and treat conditions mainly with psychotherapy and psychological assessment, while a psychiatrist can prescribe medications and other medical treatments. The roles are complementary, not ranked. The word therapist is a general term, not a single protected title in most places. Cleveland Clinic notes that a therapist has a master’s degree in a mental health related field, and examples include licensed social workers and licensed professional clinical counselors. A therapist cannot prescribe medication, so asking about a specific license and training matters more than the word alone. Psychiatric nurse practitioners complete advanced nursing education in psychiatric mental health and can assess, diagnose, provide psychotherapy, and prescribe within state scope rules, independently in some states and in collaboration with a physician in others. Neurologists and psychiatrists both deal with the brain, from different angles: Cleveland Clinic notes that a neurologist manages conditions of the brain and nervous system, while a psychiatrist focuses more on cognitive and behavioral symptoms. Primary care physicians prescribe many psychiatric medications for common depression and anxiety and are often the first professional a person speaks to. A psychiatrist becomes especially relevant when a condition is complex, severe, difficult to diagnose, not responding to initial treatment, or involves medical complications.

What to Expect at a First Appointment, in General Terms

A first appointment is usually longer than a follow up visit, because assessment takes time. The psychiatrist will ask about current concerns, history, medical background, medications, substance use, sleep, functioning, and supports, and may ask the patient to complete questionnaires. With permission, they may speak with family members or review earlier records. Toward the end, they will usually share initial impressions and agree a follow up plan. A diagnosis may be given at the first visit or described as provisional.

Preparation can help: a list of current medications, including over the counter products and supplements, a brief timeline of symptoms and previous treatments, and notes about questions to ask. Cleveland Clinic suggests similar preparation, including discussing symptom changes, physical health, and family history. Useful questions include what the diagnosis is and how it was reached, what options exist, how progress will be judged, and who to contact in an emergency related to the condition. If a patient leaves feeling unheard or confused, that is relevant to deciding whether to continue or seek another opinion. Some people see a psychiatrist once for consultation and then return to a primary care physician or therapist; others enter ongoing psychiatric care.

Choosing a Psychiatrist, Career Outlook, and Common Myths

Choosing a psychiatrist involves practical and personal factors: specialty focus, location or telehealth availability, insurance or fees, waiting times, communication style, and language. Credentials can be checked publicly: state medical board websites typically allow licensure verification, and ABPN certification can be verified through ABPN and American Board of Medical Specialties public resources. It is reasonable to seek a second opinion or change clinicians if the fit is poor.

For employment context, the Bureau lists 30,000 psychiatrist jobs in the United States in 2025, within 862,800 physician and surgeon jobs. That is an employment distribution figure, not a psychiatry only forecast. The Bureau projects employment of physicians and surgeons as a whole to grow 4 percent from 2025 to 2035, about as fast as the average for all occupations, with about 22,100 openings per year on average, largely from replacement needs, and notes that growing demand for psychiatric care will support job growth for psychiatrists. This article deliberately gives no salary figure, since pay varies widely by setting, region, hours, and experience. Working life also varies: hospital, community, academic, and private practice psychiatrists face different pressures and routines.

Several myths persist. One is that psychiatrists only prescribe medication; many provide psychotherapy, and all are trained in assessment, diagnosis, planning, and coordination. Another is that seeing a psychiatrist means severe illness or crisis; psychiatrists see a wide range of severity, including assessment and second opinions. A third is that psychiatrists and psychologists do the same job; they overlap, but training and legal powers differ. A fourth is that medication changes personality or creates dependency in all cases; effects depend on the specific medication, dose, condition, and individual, and belong in a clinical discussion. A fifth is that a psychiatrist simply tells a patient what to do; in good practice, planning is collaborative and patients can ask questions and seek second opinions.

Frequently Asked Questions

What do psychiatrists do, in one sentence?

A psychiatrist is a medical doctor who assesses, diagnoses, and treats mental, emotional, and behavioral disorders, using medical and psychological tests, medication and other medical treatments, and, in many cases, psychotherapy, while coordinating care with other health professionals.

Are psychiatrists medical doctors?

Yes. Psychiatrists hold an MD or a DO degree, complete a psychiatry residency, and must hold a medical license to practice. Board certification through the ABPN is an additional specialty credential held by many, but not all, practicing psychiatrists.

What is the difference between a psychiatrist and a psychologist?

A psychiatrist is a physician who can prescribe medication and provide medical treatments, while a psychologist typically holds a doctoral degree in psychology and treats conditions mainly with psychotherapy and psychological assessment. Psychologists generally cannot prescribe medication, with limited exceptions in a small number of states for those with additional specialized training.

Can a psychiatrist provide therapy, or do they only prescribe medication?

Some psychiatrists provide psychotherapy regularly, while others focus mainly on assessment and medication management and work with a separate therapist. Practice styles vary, so it is reasonable to ask about this when choosing care.

How long does it take to become a psychiatrist?

In the United States, the usual route is a bachelor’s degree, four years of medical school, and a psychiatry residency commonly structured over four years, with optional fellowship training of one to three years for subspecialization. The total from the start of college to independent practice is well over a decade.

What conditions do psychiatrists treat?

Psychiatrists treat a wide range, including depressive, bipolar, anxiety, obsessive compulsive, trauma related, schizophrenia spectrum, substance related, eating, sleep, neurocognitive, and personality disorders, and attention deficit hyperactivity disorder, among others, as well as complex combinations of problems and mental health difficulties alongside medical illness.

Do psychiatrists work in hospitals or only in offices?

Both. Psychiatrists work in private offices, outpatient clinics, community mental health centers, inpatient psychiatric units, general hospitals as consultation liaison psychiatrists, emergency services, academic centers, government services, and via telepsychiatry.

Is a psychiatrist the same as a neurologist?

No, though both are physicians who deal with the brain. A neurologist focuses on disorders of the brain and nervous system, including the brain, spinal cord, and nerves. A psychiatrist focuses more on cognitive, emotional, and behavioral symptoms and on mental disorders. Both may be involved when a condition overlaps both areas.

When might someone be referred to a psychiatrist?

Referral is common when a condition is complex, difficult to diagnose, severe, not responding to initial treatment, involves significant medical complications, or may require specialized medical treatments. Clinicians refer routinely, and people may also seek psychiatric care directly where permitted.

How can I check whether a psychiatrist is board certified?

Board certification in the United States is granted by the American Board of Psychiatry and Neurology. Licensure can be checked through the relevant state medical board, and board certification through ABPN and American Board of Medical Specialties public resources.
