A psychiatrist is a physician who specializes in psychiatry. A psychiatrist specializes in the diagnosis and treatment of mental disorders. Psychiatrists are medical doctors who must evaluate patients to determine whether or not their symptoms are the result of a physical illness, a combination of physical and mental, or a strictly psychiatric one. In order to do this, they may employ the psychiatric examination itself, a physical exam, brain imaging (computerized tomography or CT/CAT scan), magnetic resonance imaging (MRI), and positron emission tomography (PET) scanning), and blood laboratories. Psychiatrists prescribe medicine, and may also use psychotherapy, although the vast majority do medical management and refer to a psychologist or another specialized therapist for weekly to bi-monthly psychotherapy.
The field of psychiatry has many subspecialties (also known as Fellowships) that require additional training which are certified by the American Board of Psychiatry and Neurology (ABPN) and require Maintenance of Certification Program (MOC) to continue. The following include:
- Clinical Neurophysiology
- Forensic psychiatry
- Geriatric Psychiatry
- Hospice and Palliative Medicine
- Pain Medicine
- Psychosomatic medicine( also known as Consultation-liaison psychiatry)
- Sleep Medicine
Further, other specialties that exist include: 
- Cross-cultural psychiatry
- Emergency psychiatry
- Learning disability
- Neurodevelopmental disorder
- Cognition diseases as in various forms of dementia
Some psychiatrists specialize in helping certain age groups. Child and adolescent (pediatric) psychiatrists work with kids and teenagers in addressing psychological problems, so that they are aware of the problem. Those who work with the elderly are called geriatric psychiatrists or geropsychiatrists. Those who practice psychiatry in the workplace are called organizational and occupational psychiatrists in the U.S. (occupational psychology is the name used for the most similar discipline in the UK). Psychiatrists working in the courtroom and reporting to the judge and jury, in both criminal and civil court cases, are called forensic psychiatrists, who also treat mentally disordered offenders and other patients whose condition is such that they have to be treated in secure units.
Other psychiatrists and mental health professionals in the field of psychiatry may also specialize in psychopharmacology, psychotherapy, psychiatric genetics, neuroimaging, dementia-related disorders/ sicknesses as Alzheimer's disease, attention deficit hyperactivity disorder, sleep medicine, pain medicine, palliative medicine, eating disorders, sexual disorders, women's health, Global Mental Health, early psychosis intervention, mood disorders and anxiety disorders (including obsessive-compulsive disorder and post-traumatic stress disorder).
US and Canada
In the U.S. and Canada one must first attain the degree of M.D. or D.O., followed by practice as a psychiatric resident for another four years (five years in Canada). This extended period involves comprehensive training in psychiatric diagnosis, psychopharmacology, medical care issues, and psychotherapies. All accredited psychiatry residencies in the United States require proficiency in cognitive-behavioral, brief, psychodynamic, and supportive psychotherapies. Psychiatry residents are required to complete at least four post-graduate months of internal medicine or pediatrics, plus a minimum of two months of neurology during their first year of residency, referred to as an "internship". After completing their training, psychiatrists are eligible to take a specialty board examination to become board-certified. The total amount of time required to complete educational and training requirements in the field of psychiatry in the United States is 12 years after high school. Subspecialists in child and adolescent psychiatry are required to complete a two-year fellowship program, the first year of which can run concurrently with the fourth year of the general psychiatry residency program. This adds one to two years of training.
United Kingdom & Republic of Ireland
In the United Kingdom, psychiatrists must hold a medical degree. These degrees are often abbreviated MB BChir, MB BCh, MB ChB, BM BS, or MB BS. Following this, the individual will work as a Foundation House Officer for two additional years in the UK, or one year as Intern in the Republic of Ireland to achieve registration as a basic medical practitioner. Training in psychiatry can then begin and it is taken in two parts: three years of Basic Specialist Training culminating in the MRCPsych exam followed by three years of Higher Specialist Training, referred to as "ST4-6" in the UK and "Senior Registrar Training" in the Republic of Ireland. Candidates with MRCPsych degree and complete basic training must reinterview for higher specialist training. At this stage, the development of speciality interests such as forensic, child/adolescent take place. At the end of 3 years of higher specialist training, candidates are awarded a CCT (UK) or CCST (Ireland), both meaning Certificate of Completion of (Specialist) Training. At this stage, the psychiatrist can register as a specialist and the qualification of CC(S)T is recognized in all EU/EEA states. As such, training in the UK and Ireland is considerably longer than in the US or Canada and frequently takes around 8–9 years following graduation from medical school. Those with a CC(S)T will be able to apply for Consultant posts. Those with training from outside the EU/EEA should consult local medical boards to review their qualifications and eligibility for equivalence recognition (for example, those with a US residency and ABPN qualification).
In the Netherlands one must complete medical school after which one is certified as a medical doctor. After a strict selection program one can specialize in psychiatry: a 4.5 year specialization. During this specialization, the resident has to do a 6-month residency in the field of social psychiatry, a 12-month residency in a field of their own choice (which can be child psychiatry, forensic psychiatry, somatic medicine or medical research). To become an adolescent psychiatrist, one has to do an extra specialization period of 2 more years. In short this means that it takes at least 10.5 years of study to become a psychiatrist which can go up to 12.5 years if one becomes a children's and adolescent psychiatrist.
