What Does a Psychiatrist Do? A Complete Guide to Services and When to Go

Someone, maybe a friend, a doctor, or your own instinct, has suggested you see a psychiatrist, and you’re not entirely sure what that actually means. Does a psychiatrist just hand out prescriptions? Is it the same as therapy? Do you have to be in crisis to justify the appointment? These are reasonable questions, and the uncertainty around them is one of the biggest reasons people delay getting help they could benefit from.

What Is a Psychiatrist?

A psychiatrist is a medical doctor, holding an MD or DO degree, who specializes in diagnosing, treating, and preventing mental health conditions. According to the American Psychiatric Association, psychiatry is a medical specialty devoted to the diagnosis, prevention, and treatment of mental, emotional, and behavioral disorders. Because psychiatrists complete full medical school training before specializing, they evaluate mental health symptoms within the broader context of physical health, bringing a medical lens to conditions that can have overlapping physical and psychological causes.

This medical training is what allows psychiatrists to prescribe medication, order and interpret lab work or imaging when relevant, and identify when a physical health condition, such as a thyroid disorder or vitamin deficiency, might be contributing to psychiatric symptoms. It is also the foundation for offering advanced medical treatments such as TMS therapy for depression that has not responded to medication alone.

Psychiatrist vs. Therapist vs. Psychologist: Key Differences

The terms psychiatrist, therapist, and psychologist are often used interchangeably in everyday conversation, but they represent distinct professions with different training, scope of practice, and roles in mental health care.

Many patients benefit most from a combination: a psychiatrist for diagnosis and medication management, and a therapist for ongoing weekly talk therapy. Prime Behavioral Health coordinates with existing therapists or provides referrals when this combined approach fits a patient’s needs.

What a Psychiatrist Actually Does: Core Services

Comprehensive Psychiatric Evaluation and Diagnosis

The foundation of psychiatric care is an accurate diagnosis. A psychiatrist reviews symptom history, medical background, family psychiatric history, and prior treatment responses to determine what is actually driving a patient’s symptoms, distinguishing between conditions like depression, anxiety, ADHD, bipolar disorder, and other conditions that can present with overlapping symptoms.

Medication Management

Prescribing and monitoring medication is one of the most defining functions of a psychiatrist. This is not a one-time prescription. Medication management is an active, ongoing clinical process that includes selecting an appropriate medication, monitoring for effectiveness and side effects at follow-up visits, and adjusting the treatment plan as needed over time.

Advanced Treatments Beyond Medication

For patients who have not achieved adequate relief from medication alone, psychiatrists can offer or refer for advanced treatments. Prime Behavioral Health provides FDA-approved NeuroStar TMS therapy for treatment-resistant depression, along with GeneSight DNA testing to help guide medication selection based on individual genetics.

Therapy and Behavioral Guidance

Some psychiatrists, including Dr. Shah at Prime Behavioral Health, are trained in specific therapeutic modalities such as Cognitive Behavioral Therapy (CBT) and Dialectical Behavioral Therapy (DBT). Even when a psychiatrist’s appointment time is primarily focused on evaluation and medication, most provide behavioral guidance and coordinate referrals for ongoing weekly therapy when that additional support is appropriate.

Ongoing Monitoring and Follow-Up Care

Psychiatric care does not end after diagnosis and an initial prescription. Regular follow-up appointments allow a psychiatrist to track progress, catch side effects or complications early, and adjust the treatment plan as a patient’s symptoms and life circumstances change over time.

What Happens During Your First Psychiatric Appointment

A first psychiatric appointment is a comprehensive evaluation, typically lasting 60 to 90 minutes. Here is what to expect:

  • A detailed review of your current symptoms, including how long they have been present and how they affect your daily life
  • Questions about your mental health history, including any prior diagnoses, treatments, or hospitalizations
  • A review of your medical history and current medications, since physical health and psychiatric symptoms often interact
  • Questions about family psychiatric history, since many conditions have a genetic component
  • A discussion of your goals for treatment and what you hope to achieve
  • A preliminary diagnosis, when appropriate, and a discussion of recommended treatment options

You are encouraged to ask questions throughout the appointment. Bringing a list of current medications, any prior treatment records, and a summary of your symptom history helps the evaluation move efficiently. No referral is required to schedule.

Common Misconceptions About Psychiatrists

Misconception: Psychiatrists Only Treat Severe Mental Illness

Psychiatrists treat the full range of mental health conditions, from mild situational anxiety to severe, complex presentations. Waiting until symptoms become severe before seeking a psychiatric evaluation often means missing the point at which treatment is simplest and most effective.

Misconception: A Psychiatrist Will Just Prescribe Medication Regardless of What I Say

Medication is one tool among several, not an automatic outcome of every appointment. A thorough evaluation may lead to a recommendation for medication, therapy referral, lifestyle changes, TMS therapy, or some combination, depending entirely on what the evaluation reveals about your specific situation.

Misconception: Seeing a Psychiatrist Means Something Is Seriously Wrong With Me

A psychiatric evaluation is a medical evaluation, similar in spirit to seeing a cardiologist for heart palpitations or an endocrinologist for fatigue. It reflects taking a set of symptoms seriously enough to get an expert opinion, not evidence that something is fundamentally wrong with you as a person.

When Should You See a Psychiatrist?

Consider scheduling a psychiatric evaluation if you notice any of the following:

  • Mood, anxiety, attention, sleep, or behavior symptoms that have persisted for several weeks or longer
  • Symptoms that are interfering with work, school, relationships, or your ability to function day to day
  • Prior attempts at self-help strategies or therapy that have not produced adequate improvement
  • A desire for clarity about a diagnosis, even if your symptoms feel manageable right now
  • A family member or friend has expressed concern about changes they have noticed in you

You do not need to be in crisis to justify a psychiatric evaluation. For a deeper look at specific signs, see our guide on when to seek help and recognizing the signs you might need a psychiatrist.

Can Children and Teens See a Psychiatrist?

Yes. Child and adolescent psychiatry is a distinct subspecialty requiring additional training beyond general adult psychiatric residency. Dr. Vishal Shah is dual board-certified in Adult and Child/Adolescent Psychiatry, completing a two-year fellowship at Akron Children’s Hospital specifically in this area. Barbara Schoen Johnson, PhD, APRN, PMHNP, brings 16 years of pediatric psychiatric nursing experience from Cook Children’s Behavioral Health Outpatient Clinic. Prime Behavioral Health provides age-appropriate psychiatric evaluation and treatment for children, adolescents, and adults, including adolescent psychiatric care that involves parents throughout the treatment process.

Frequently Asked Questions About What a Psychiatrist Does

What does a psychiatrist do?

A psychiatrist is a medical doctor who specializes in diagnosing, treating, and preventing mental health conditions. Psychiatrists evaluate symptoms, order and interpret relevant medical tests, diagnose psychiatric conditions, prescribe and manage medications, and in some practices provide therapy directly. Because psychiatrists complete full medical training before specializing in psychiatry, they are equipped to consider how physical health, medications, and neurological factors interact with mental health symptoms, something professionals without a medical degree cannot do.

What is the difference between a psychiatrist and a therapist?

A psychiatrist is a medical doctor (MD or DO) who can prescribe medication, order medical tests, and manage complex psychiatric conditions from a medical standpoint. A therapist, which may include licensed professional counselors, licensed clinical social workers, or licensed marriage and family therapists, provides talk therapy but cannot prescribe medication in Texas. Many patients benefit from working with both: a psychiatrist for diagnosis and medical management, and a therapist for ongoing talk therapy. Prime Behavioral Health can coordinate with an existing therapist or provide referrals when both types of care are appropriate.

What is the difference between a psychiatrist and a psychologist?

A psychiatrist completes medical school and a psychiatric residency, earning an MD or DO degree, which allows them to prescribe medication. A psychologist typically holds a PhD or PsyD in psychology, focuses on psychological testing and talk therapy, and in most states, including Texas, cannot prescribe medication. Psychologists often specialize in specific therapeutic approaches or diagnostic testing, while psychiatrists specialize in the medical management of mental health conditions, including medication and, at practices like Prime Behavioral Health, advanced treatments such as TMS therapy.

Can a psychiatrist prescribe medication?

Yes. Prescribing and managing medication is one of the core functions of a psychiatrist and one of the primary features that distinguishes psychiatrists from therapists and psychologists. Medication management at Prime Behavioral Health is an active, ongoing process that includes initial prescribing, regular follow-up appointments, monitoring for side effects and effectiveness, and dosage adjustments as needed over time.

Do I need a referral to see a psychiatrist?

No. Prime Behavioral Health does not require a referral to schedule a psychiatric evaluation. You can call 817-778-8884 or complete the online appointment request form directly. Some insurance plans may have their own requirements, so it is worth confirming your specific plan’s policy, but no physician referral is needed to begin the scheduling process.

What conditions do psychiatrists treat?

Psychiatrists treat a wide range of mental health conditions including depression, anxiety disorders, ADHD, PTSD, OCD, bipolar disorder, insomnia and other sleep disorders, schizophrenia, neurodevelopmental disorders, and disruptive behavior disorders. At Prime Behavioral Health, our board-certified psychiatrist and licensed psychiatric team treat children, adolescents, and adults across this full range of conditions, from initial evaluation through medication management and advanced treatments including TMS therapy.

What happens during a first appointment with a psychiatrist?

Your first psychiatric appointment is a comprehensive evaluation typically lasting 60 to 90 minutes. Your psychiatrist reviews your current symptoms, mental health history, medical history, family psychiatric history, current medications, and how your symptoms are affecting your daily life and functioning. Based on this evaluation, your provider shares a preliminary diagnosis if appropriate and discusses treatment options. You are encouraged to ask questions throughout the appointment.

How is a psychiatrist different from my primary care doctor for mental health concerns?

Primary care doctors can prescribe some basic psychiatric medications and provide initial screening for common conditions like mild depression or anxiety, but they do not have the specialized training in psychiatric diagnosis, medication management for complex or treatment-resistant conditions, or access to advanced treatments like TMS therapy that a psychiatrist has. When symptoms are moderate to severe, do not improve with initial treatment, or involve a more complex diagnostic picture, a psychiatric evaluation provides a level of expertise a primary care visit is not designed to offer.

Why would someone see a psychiatrist instead of just a therapist?

Someone might see a psychiatrist instead of, or in addition to, a therapist when medication may be part of an effective treatment plan, when symptoms are complex enough to require a medical diagnostic evaluation, when a condition has not improved with therapy alone, or when advanced treatments such as TMS therapy are being considered for treatment-resistant depression. A psychiatrist’s medical training allows them to evaluate whether an underlying medical condition or medication interaction might be contributing to psychiatric symptoms, which is outside a therapist’s scope of practice.

Can a psychiatrist also provide therapy?

Some psychiatrists, including Dr. Vishal Shah at Prime Behavioral Health, are trained in specific therapeutic approaches such as Cognitive Behavioral Therapy (CBT), Dialectical Behavioral Therapy (DBT), Interpersonal Therapy (IPT), and Motivational Interviewing. However, most psychiatric practices, including ours, primarily focus appointment time on evaluation, diagnosis, and medication management, and provide referrals to therapists for ongoing weekly talk therapy, since therapy typically requires more frequent sessions than psychiatric follow-up visits.

What is the difference between a psychiatrist and a psychiatric nurse practitioner?

A psychiatrist holds a medical degree (MD or DO) and completes a psychiatric residency. A Psychiatric Mental Health Nurse Practitioner (PMHNP) holds an advanced nursing degree (MSN or DNP) with specialized psychiatric certification and, in Texas, can evaluate, diagnose, and prescribe medication for mental health conditions, often working collaboratively with a supervising or collaborating psychiatrist. At Prime Behavioral Health, our four PMHNPs work alongside board-certified psychiatrist Dr. Vishal Shah to provide a broader range of appointment availability while maintaining consistent, physician-informed care standards.

Do psychiatrists only treat severe mental illness?

No. This is a common misconception that keeps people from seeking help earlier than they need to. Psychiatrists treat the full spectrum of mental health conditions, from mild to severe, including situational anxiety, mild depression, ADHD, and sleep difficulties, not only conditions like schizophrenia or severe bipolar disorder. Earlier treatment for milder symptoms often produces better outcomes and prevents conditions from becoming more severe or entrenched over time.

What training does a psychiatrist have?

A psychiatrist completes four years of undergraduate education, four years of medical school earning an MD or DO degree, and then a psychiatric residency, typically three to four years for adult psychiatry, with an additional two years for those who also specialize in child and adolescent psychiatry. Dr. Vishal Shah at Prime Behavioral Health completed a three-year Adult Psychiatry Residency at Howard University Hospital and a two-year Child and Adolescent Psychiatry Fellowship at Akron Children’s Hospital, and is board certified in both specialties.

Can children and teens see a psychiatrist?

Yes. Child and adolescent psychiatry is a distinct subspecialty requiring additional fellowship training beyond general adult psychiatric residency. Dr. Vishal Shah is board certified in both Adult and Child/Adolescent Psychiatry, and Barbara Schoen Johnson, PhD, APRN, PMHNP brings 16 years of pediatric psychiatric nursing experience from Cook Children’s Behavioral Health Outpatient Clinic. Prime Behavioral Health provides psychiatric evaluation and treatment for children, adolescents, and adults.

How do I know if I need to see a psychiatrist?

Consider scheduling a psychiatric evaluation if your mood, anxiety, attention, sleep, or behavior symptoms have persisted for several weeks, if symptoms are interfering with work, school, relationships, or daily functioning, if you have tried self-help strategies or therapy without adequate improvement, or if you simply want clarity about what you are experiencing. You do not need to be in crisis to benefit from a psychiatric evaluation. Early evaluation often leads to more treatment options and better outcomes than waiting until symptoms become severe.
