A psychiatrist is a medical doctor who diagnoses and treats mental illness. They take a full history, order laboratory and psychological tests, apply DSM-5 criteria to reach a diagnosis, prescribe and adjust psychiatric medication, and build a treatment plan with you. Some also provide talk therapy themselves.
The medical part is what separates psychiatry from every other mental health profession. Here’s what that training covers, what a psychiatrist actually does in a week, how the subspecialties work, and where the boundary sits between psychiatry and psychology.
What a psychiatrist does, step by step
The American Psychiatric Association defines psychiatry as the branch of medicine focused on the diagnosis, treatment, and prevention of mental, emotional, and behavioral disorders. A psychiatrist is an M.D. or a D.O. who specializes in that field, including substance use disorders. The association’s own wording is worth quoting: “Psychiatrists are qualified to assess both the mental and physical aspects of psychological problems.” That single line explains most of what follows.
In practice, the work breaks into six recurring tasks.
- Evaluate. A long first appointment covering symptoms, medical history, family history, sleep, substances, and daily function.
- Test. Because they are physicians, psychiatrists can order or perform a full range of medical laboratory and psychological tests.
- Diagnose. Specific diagnoses rest on the criteria in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition.
- Treat. Talk therapy, drugs, social support, and procedures such as electroconvulsive therapy, picked for each patient.
- Monitor. Follow up visits track your response, side effects, and lab results, and adjust the dose.
- Coordinate. Working with a therapist, a family doctor, and other healthcare professionals so the pieces fit.
That second point is the one people miss. Thyroid disease, sleep apnea, anemia, low iron, and drug side effects all mimic a mental health condition. A psychiatrist is trained to rule those out before treating what looks like depression.
How long does it take to become a psychiatrist?
Roughly 12 years after high school for general adult psychiatry, and up to 14 years for child and adolescent psychiatry. The APA breaks that medical training down clearly.
| Stage | Length | What it covers |
|---|---|---|
| Undergraduate degree | 4 years | Prerequisites for medical school |
| Medical school | 4 years | The same degree every physician earns |
| Residency, first year | 1 year | Hospital work with a wide range of medical illnesses |
| Residency, remaining years | At least 3 years | Diagnosis, talk therapy, psychiatric medication, and other care |
| Board certification | After residency | A voluntary written and oral exam, re-certified every 10 years |
| Fellowship, if chosen | 1 to 2 years | A subspecialty such as addiction psychiatry or geriatric psychiatry |
Residency training happens in offices, hospitals, emergency rooms, and community sites including primary care. Most psychiatrists then sit the American Board of Psychiatry and Neurology exam to become board certified, and re-certify every decade.
The subspecialties of psychiatry
Eight fellowships are accredited by the Accreditation Council on Graduate Medical Education, and they shape what a given psychiatrist sees day to day.
- Addiction psychiatry or addiction medicine, for substance use disorders alongside mental health conditions.
- Child and adolescent psychiatry, the longest training path in the field.
- Consultation-liaison psychiatry, for patients with tangled medical and psychiatric problems.
- Forensic psychiatry, for patients involved in the legal or correctional system.
- Geriatric psychiatry, for older adults, where dementia and medication interactions dominate.
- Hospice and palliative medicine, for patients with serious illness.
- Pain medicine and sleep medicine, both of which overlap heavily with mood and anxiety.
Unaccredited fellowships exist too, including emergency psychiatry, public and community psychiatry, and reproductive psychiatry for pregnant and postpartum patients. A forensic psychiatrist spends time in courtrooms; a geriatric psychiatrist spends it in care homes. Same degree, different working life.
Some physicians train in two specialties at once to care for complex patients. That combination is common in addiction medicine, where the medical treatment and the mental health treatment cannot be separated.
Twelve years. Read that again.
And it explains something patients find odd at a first visit. The blood pressure cuff. The thyroid question. The bag of pill bottles you were asked to bring. But a psychiatrist trained as a physician first, so the body comes into the room whether you raised it or not.
Psychiatrist, psychologist, or therapist?
These three roles get used interchangeably, and they are not the same. The differences matter mostly for what each person can offer you.
| Role | Training | Prescribes | Main tools |
|---|---|---|---|
| Psychiatrist | Medical degree plus psychiatry residency | Yes | Diagnosis, drugs, tests, talk therapy |
| Psychologist | Doctorate in psychology | Rarely, and only in a few states | Talk therapy, mental health testing |
| Licensed therapist or counselor | Master’s degree plus supervised hours | No | Talk therapy, skills work, group therapy |
| Psychiatric nurse practitioner | Nursing degree plus psychiatric specialty | Yes | Diagnosis, drugs, follow up |
Plenty of patients work with two of these at once. A common setup pairs a psychiatrist for medication management with a therapist for weekly cognitive behavioral therapy. Neither replaces the other, and the pairing beats either alone for many mental disorders.

What conditions does a psychiatrist treat?
The range is wider than most people expect, and it includes physical illness tangled up with mental health issues.
- Depression, including treatment resistant depression and the kind that follows a birth.
- Anxiety disorders, panic disorder, and PTSD.
- Bipolar disorder and other mood disorders.
- Schizophrenia and psychotic disorders.
- Obsessive compulsive disorder and related conditions.
- ADHD in adults and children.
- Personality disorders, including borderline personality disorder.
- Eating disorders, alongside medical and diet care.
- Substance use disorders, including opioid and alcohol use disorder.
- Dementia and the behavioral changes that come with it.
A psychiatrist also handles the overlap. Someone with opioid use disorder and depression needs both treated together, which is why addiction psychiatry exists as a subspecialty at all.
What treatments do psychiatrists use?
More than prescriptions. The APA lists talk therapy, drugs, social support, and other care such as electroconvulsive therapy, picked to fit each patient.
Psychotherapy, sometimes called talk therapy, is a treatment built on a talking relationship between a therapist and a patient. Its goal is to reduce or control troubling symptoms so the patient can function better. Psychiatrists train in it during residency. Some give it themselves.
Drugs are the tool people link with psychiatry, and they deserve a fair hearing. A pill is not a life sentence. It does not change who you are. It works best when someone is watching the dose. The APA is blunt: patients on long-term treatment “will need to meet with their psychiatrist periodically to monitor the effectiveness of the medication and any potential side effects”. Follow up is not optional. A good treatment plan names a target, a review date, and a plan B if the first try falls flat.
Newer options sit next to the old ones. TMS and Spravato are used in treatment resistant depression. Brain mapping helps some clinics tailor a plan. Ask what proof backs any treatment option before you say yes to it. Our team at Foundation Medical Group expects that question and answers it.
Names help here. Foundation Medical Group runs psychiatric care out of Richmond, Virginia, Decatur, Georgia, Dallas, Texas, and American Fork, Utah. The medical directors are physicians: Dr Vincent Nardone, Dr William Epps, Dr Justin Thompson, and Dr Paul Frandsen.
And that matters more than it sounds. A title tells you what someone can prescribe. It doesn’t tell you whether they’ll listen, which is the part patients actually worry about.
For example, a psychiatric nurse practitioner can prescribe, whereas a psychologist in most states cannot. So compare what each role can actually do, rather than which title sounds most senior. Ask about the tools someone uses, such as medication reviews or talk therapy.
Who actually sees a psychiatrist?
More people than you would guess. According to the National Institute of Mental Health, 59.3 million U.S. adults lived with a mental illness in 2022. That is 23.1 percent of adults, or more than one in five.
Of those 59.3 million, 30.0 million received any mental health treatment in the past year. That is 50.6 percent. Put plainly: half of the people who could use care did not get it.
Unfortunately the gap is wider for men. Among adults with a mental illness, 56.9 percent of women got treatment against 41.6 percent of men. Young adults aged 18 to 25 sat at 49.1 percent, slightly below older groups.
Treatment in that count means inpatient or outpatient counseling, or a prescription for mental health. So the number includes people who never saw a psychiatrist at all. Many are treated by a family doctor, and that works fine for straightforward cases.
A psychiatrist earns their place when the picture gets complicated. Two diagnoses at once. A drug that stopped working. A medical illness that muddies the water. Or a plan that has not moved in six months.
Which raises a fair question. Do you actually need one?
Often not. A good family doctor manages plenty of straightforward depression, and Foundation Medical Group refers in both directions. But when two conditions overlap, or a drug that worked stops working, the medical training starts to earn its keep.
What happens at a first appointment?
Expect a long talk, not a quick script. In our experience most patients arrive nervous about that hour, and the questions they bring shape it more than they expect. A first visit runs 45 to 60 minutes in most clinics. It covers your symptoms, your medical history, your pills, your sleep, your drug and drink use, and what a bad week looks like.
You will be asked about family history, because genes matter. You will be asked about thoughts of self harm, because each visit should. Patients often worry that saying yes sets something dramatic in motion. It does not. Blood work may be ordered. None of it locks you into a drug, and for a lot of patients that is the biggest relief of the hour.
Bring three things. A list of what you take, herbs and vitamins too. A note of what you have already tried. A short line on what you want to change. Our patients who bring those three get far more out of the hour.
Is a psychiatrist right for you?
Here is a short test. If two or more of these fit, book a visit.
You have tried talk therapy and hit a wall. A drug helped once and then stopped. You take three or more pills for your mood. You have a health issue that muddies the picture. You have had a manic spell. Or nobody has ever put a name to what you have.
None of that means you are a hard case. It means the plan needs a doctor who does this all day. A family doctor treats mild cases well and knows when to hand one on.
The reverse is true too. If your main need is to talk, and you sleep and eat fine, a therapist may serve you better and cost less. Ask for what you need, not for the biggest title.
