Mental health is just as important as physical health, yet many people are unsure about what psychiatrists actually do, or when it might be time to see one. At Cantera Psychiatry in San Antonio, TX, we believe in treating your mental health holistically, with compassionate and personalized care that goes beyond prescriptions alone.
If you’ve ever wondered what a psychiatrist does and how they can help, this simple guide breaks it down.
Who Is a Psychiatrist?
A psychiatrist is a medical doctor (MD or DO) who specializes in diagnosing, treating, and preventing mental, emotional, and behavioral conditions. In the state of Texas, only a psychiatrist (MD or DO) can:
- Prescribe stimulant medications
- Conduct medical and psychiatric evaluations
- Provide psychotherapy (“talk therapy”)
- Offer advanced treatments such as Spravato (esketamine), Theta Burst Stimulation (TBS), and Transcranial Magnetic Stimulation (TMS)
This medical training allows psychiatrists to address both the mind and body, creating a comprehensive care plan for each patient.
What Does a Psychiatrist Do?
Psychiatrists play a vital role in supporting people through all stages of mental health care. Some of their key responsibilities include:
1. Comprehensive Evaluation
Your first visit often involves a detailed conversation about your symptoms, medical history, and family background. Psychiatrists may also use lab work or psychological assessments to rule out other causes.
2. Diagnosis
Using tools like the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders), psychiatrists diagnose conditions ranging from depression and anxiety to bipolar disorder, PTSD, and more.
3. Personalized Treatment Planning
No two patients are alike. Psychiatrists develop tailored treatment plans, which may include therapy, medication, advanced treatments, or a combination.
4. Medication Management
Psychiatrists are experts in psychopharmacology. They prescribe medications to regulate brain chemistry and monitor progress, adjusting dosages for maximum benefit with minimal side effects.
5. Psychotherapy
Many psychiatrists, including those at Cantera, also provide therapy to help patients better understand and manage their thoughts, emotions, and behaviors.
6. Advanced Interventions
For treatment-resistant conditions, psychiatrists can provide medical options like Spravato, TBS, and TMS, which are especially effective for patients who haven’t found relief with traditional antidepressants.
7. Crisis Intervention
In emergencies, such as severe mood episodes, suicidal thoughts, or psychosis, psychiatrists are trained to stabilize and support patients quickly.
8. Collaboration With Other Providers
Psychiatrists often work with psychologists, therapists, and primary care doctors to ensure holistic, well-rounded care.
Conditions Psychiatrists Treat

Psychiatrists are trained to manage a wide range of mental health conditions, including but not limited to:
- Anxiety disorders (panic disorder, OCD, phobias)
- Depression and bipolar disorder
- ADHD
- Schizophrenia and other psychotic disorders
- PTSD and trauma-related disorders
- Substance use and addiction
- Eating disorders
- Personality disorders
Psychiatrist vs. Psychologist: What’s the Difference?
It’s common to confuse these two roles, but they’re distinct:
- Psychiatrist – A medical doctor who can prescribe medication, provide therapy, and address both the mental and physical aspects of conditions.
- Psychologist – Holds a Ph.D. or Psy.D. and typically focuses on therapy, psychological testing, and research. In most states, psychologists cannot prescribe medication.
Both professionals are important to mental health care, but if your symptoms may require medication or advanced interventions, a psychiatrist is often the best starting point.
