Psychiatrists are medical doctors who diagnose and treat mental health conditions using a combination of medication, therapy, and medical procedures. Unlike psychologists and therapists, psychiatrists complete medical school and can prescribe drugs, order lab tests, and perform physical exams. Their training typically spans 12 or more years after high school: four years of college, four years of medical school, and a four-year residency, with some adding one to two more years in a fellowship subspecialty.
Evaluating and Diagnosing Patients
A large part of a psychiatrist’s work is figuring out what’s going on. An initial psychiatric evaluation usually takes 60 to 90 minutes and covers a patient’s symptoms, personal history, family mental health history, medical conditions, and current medications. Because psychiatrists are trained as physicians, they also consider whether a physical problem (a thyroid disorder, a brain injury, a medication side effect) could be causing or worsening psychiatric symptoms. They may order blood work, brain imaging, or other tests that a non-physician therapist cannot.
During the evaluation, psychiatrists conduct what’s called a mental status examination. This isn’t a written test for the patient. It’s a structured observation of how someone looks, speaks, thinks, and behaves during the appointment. The psychiatrist notes things like mood, thought patterns, concentration, memory, and whether someone is experiencing hallucinations or delusions. All of this information gets weighed against standardized diagnostic criteria to arrive at a diagnosis like major depression, bipolar disorder, PTSD, or schizophrenia.
Prescribing and Managing Medication
Prescribing psychiatric medication is one of the clearest distinctions between psychiatrists and other mental health professionals. Only six U.S. states allow psychologists to prescribe, and those programs require far less training. Psychiatrists accumulate between 12,000 and 16,000 hours of direct patient care during residency alone, giving them deep familiarity with how these drugs interact with the rest of the body.
Psychiatric medications can affect heart rhythm, liver function, metabolism, and hormones. A psychiatrist monitors for these effects, adjusts dosages over time, and manages combinations of medications when a patient has multiple conditions. Follow-up appointments, which are often shorter than the initial evaluation (15 to 30 minutes), focus heavily on how the medication is working, what side effects have appeared, and whether a change is needed. This ongoing fine-tuning is a core part of the job.
Providing Therapy
Many people assume psychiatrists only prescribe pills, but plenty also provide psychotherapy. Some psychiatrists offer cognitive behavioral therapy, psychodynamic therapy, or other talk-based treatments alongside medication management. In practice, whether a psychiatrist does therapy depends on their setting and patient load. A psychiatrist in a busy clinic may focus on medication and refer patients to a therapist for weekly sessions, while one in private practice may do both.
Performing Medical Procedures
Psychiatry has moved well beyond just medication and talk therapy. A growing area called interventional psychiatry involves hands-on medical treatments for patients who haven’t responded to standard approaches.
- Transcranial magnetic stimulation (TMS) uses brief magnetic pulses directed at specific areas of the brain. It’s FDA-approved for major depression and OCD, is noninvasive, and doesn’t require anesthesia.
- Electroconvulsive therapy (ECT) involves brief general anesthesia and a controlled electrical stimulation of the brain. It remains one of the most effective treatments for severe depression and catatonia.
- Esketamine is a nasal spray related to ketamine, FDA-approved for treatment-resistant depression and depression with suicidal thoughts. It’s administered in a supervised medical setting, initially twice a week for four weeks.
- Deep brain stimulation (DBS) is a surgical approach used in some cases of treatment-resistant OCD, involving implanted electrodes that modulate brain activity.
Psychiatrists in interventional clinics evaluate which patients are good candidates for these treatments, administer or oversee them, and monitor outcomes over time.
Working Across Different Settings
Where a psychiatrist works dramatically shapes what their day looks like.
In an inpatient hospital unit, psychiatrists treat people in acute crisis: someone experiencing psychosis, a severe manic episode, or active suicidal intent. The work is fast-paced and involves daily rounds, rapid medication adjustments, coordination with nurses and social workers, and decisions about when a patient is stable enough to be discharged. Patients in these settings often have serious, sometimes life-threatening conditions that require close monitoring.
In an outpatient office or private practice, the pace is different. Patients come in for scheduled appointments, and the focus is on long-term management of conditions like anxiety, depression, ADHD, or bipolar disorder. The psychiatrist builds relationships with patients over months or years, tracking how they respond to treatment and making gradual adjustments.
A third model is collaborative care, where a psychiatrist works as a consultant embedded within a primary care team. Rather than seeing every patient directly, the psychiatrist reviews cases with a care manager, recommends treatment changes for patients who aren’t improving, and steps in for direct consultations when needed. This model extends a single psychiatrist’s reach to far more patients than a traditional practice allows.
Telepsychiatry has also become a major part of the field. In 2024, more than 7 million prescriptions for controlled medications were issued through telemedicine without a prior in-person visit. Federal flexibilities allowing this have been extended through 2026 while permanent rules are developed, making remote psychiatric care a lasting feature of the profession rather than a pandemic-era workaround.
Subspecialties Within Psychiatry
After completing a general psychiatry residency, some psychiatrists pursue fellowship training in a specific area. These subspecialties each come with distinct patient populations and responsibilities.
Child and adolescent psychiatry (two-year fellowship) focuses on young people and their families. These psychiatrists treat developmental conditions like ADHD and autism, behavioral issues stemming from trauma or family conflict, and first episodes of depression, anxiety, eating disorders, or psychosis in teenagers.
Addiction psychiatry (one-year fellowship) centers on preventing and treating substance use disorders and behavioral addictions like gambling. Beyond individual patient care, addiction psychiatrists often help develop community-level programs and policies around drug and alcohol use.
Forensic psychiatry (one-year fellowship) sits at the intersection of mental health and the legal system. Forensic psychiatrists evaluate criminal defendants to determine whether they were mentally competent at the time of an offense, assess risks of violence and reoffending, and treat mentally ill individuals within the justice system. They frequently testify in court.
Geriatric psychiatry (one-year fellowship) addresses the unique mental health challenges of aging, including dementia, late-life depression, and the psychological effects of chronic illness or social isolation. These psychiatrists work closely with nurses, social workers, and primary care physicians.
Other subspecialties include sleep medicine, pain management, hospice and palliative medicine, and consultation-liaison psychiatry (treating psychiatric issues in patients hospitalized for medical conditions).
Compensation and Training Investment
The training pipeline is long, but it leads to strong earning potential. The median annual salary for psychiatrists exceeded $239,200 as of May 2023, according to the Bureau of Labor Statistics. Demand remains high because of a nationwide shortage of psychiatrists, particularly in rural areas and child/adolescent care. This shortage is one reason collaborative care models and telepsychiatry have expanded so quickly.
The total education path typically looks like this: four years of undergraduate study, four years of medical school, four years of psychiatry residency, and an optional one to two years of fellowship. That’s 12 to 14 years of post-high school training before practicing independently in a subspecialty.
