Neurology is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the nervous system, which comprises the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system.
A psychiatrist is a physician who specializes in psychiatry. Psychiatrists are physicians and evaluate patients to determine whether their symptoms are the result of a physical illness, a combination of physical and mental ailments or strictly mental issues. Sometimes a psychiatrist works within a multi-disciplinary team, which may comprise clinical psychologists, social workers, occupational therapists, and nursing staff. Psychiatrists have broad training in a biopsychosocial approach to the assessment and management of mental illness.
A psychiatric or psychotropic medication is a psychoactive drug taken to exert an effect on the chemical makeup of the brain and nervous system. Thus, these medications are used to treat mental illnesses. These medications are typically made of synthetic chemical compounds and are usually prescribed in psychiatric settings, potentially involuntarily during commitment. Since the mid-20th century, such medications have been leading treatments for a broad range of mental disorders and have decreased the need for long-term hospitalization, thereby lowering the cost of mental health care. The recidivism or rehospitalization of the mentally ill is at a high rate in many countries, and the reasons for the relapses are under research.
The American Psychiatric Association (APA) is the main professional organization of psychiatrists and trainee psychiatrists in the United States, and the largest psychiatric organization in the world. It has more than 37,000 members who are involved in psychiatric practice, research, and academia representing a diverse population of patients in more than 100 countries. The association publishes various journals and pamphlets, as well as the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM codifies psychiatric conditions and is used mostly in the United States as a guide for diagnosing mental disorders.
Opioid use disorder (OUD) is a substance use disorder characterized by cravings for opioids, continued use despite physical and/or psychological deterioration, increased tolerance with use, and withdrawal symptoms after discontinuing opioids. Opioid withdrawal symptoms include nausea, muscle aches, diarrhea, trouble sleeping, agitation, and a low mood. Addiction and dependence are important components of opioid use disorder.
Emergency psychiatry is the clinical application of psychiatry in emergency settings. Conditions requiring psychiatric interventions may include attempted suicide, substance abuse, depression, psychosis, violence or other rapid changes in behavior.
Addiction medicine is a medical subspecialty that deals with the diagnosis, prevention, evaluation, treatment, and recovery of persons with addiction, of those with substance-related and addictive disorders, and of people who show unhealthy use of substances including alcohol, nicotine, prescription medicine and other illicit and licit drugs. The medical subspecialty often crosses over into other areas, since various aspects of addiction fall within the fields of public health, psychology, social work, mental health counseling, psychiatry, and internal medicine, among others. Incorporated within the specialty are the processes of detoxification, rehabilitation, harm reduction, abstinence-based treatment, individual and group therapies, oversight of halfway houses, treatment of withdrawal-related symptoms, acute intervention, and long term therapies designed to reduce likelihood of relapse. Some specialists, primarily those who also have expertise in family medicine or internal medicine, also provide treatment for disease states commonly associated with substance use, such as hepatitis and HIV infection.
A mental health professional is a health care practitioner or social and human services provider who offers services for the purpose of improving an individual's mental health or to treat mental disorders. This broad category was developed as a name for community personnel who worked in the new community mental health agencies begun in the 1970s to assist individuals moving from state hospitals, to prevent admissions, and to provide support in homes, jobs, education, and community. These individuals were the forefront brigade to develop the community programs, which today may be referred to by names such as supported housing, psychiatric rehabilitation, supported or transitional employment, sheltered workshops, supported education, daily living skills, affirmative industries, dual diagnosis treatment, individual and family psychoeducation, adult day care, foster care, family services and mental health counseling.
A combined internal medicine and psychiatry residency program is a post-graduate medical education program in the United States, which leads to board eligibility in both internal medicine and psychiatry. That is, a graduate of the residency is both an internist as well as a psychiatrist. The program takes five years of post-graduate medical training. There are 12 such programs in the country, and around eighteen positions available for new applicants.
In the United States, a psychiatric-mental health nurse practitioner (PMHNP) is an advanced practice registered nurse trained to provide a wide range of mental health services to patients and families in a variety of settings. PMHNPs diagnose, conduct therapy, and prescribe medications for patients who have psychiatric disorders, medical organic brain disorders or substance abuse problems. They are licensed to provide emergency psychiatric services, psychosocial and physical assessment of their patients, treatment plans, and manage patient care. They may also serve as consultants or as educators for families and staff. The PMHNP has a focus on psychiatric diagnosis, including the differential diagnosis of medical disorders with psychiatric symptoms, and on medication treatment for psychiatric disorders.
Dual diagnosis is the condition of having a mental illness and a comorbid substance use disorder. There is considerable debate surrounding the appropriateness of using a single category for a heterogeneous group of individuals with complex needs and a varied range of problems. The concept can be used broadly, for example depression and alcohol use disorder, or it can be restricted to specify severe mental illness and substance use disorder, or a person who has a milder mental illness and a drug dependency, such as panic disorder or generalized anxiety disorder and is dependent on opioids. Diagnosing a primary psychiatric illness in people who use substances is challenging as substance use disorder itself often induces psychiatric symptoms, thus making it necessary to differentiate between substance induced and pre-existing mental illness.
Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of deleterious mental conditions. These include various matters related to mood, behaviour, cognition, and perceptions.
Bankole A. Johnson, DSc, MD, MPhil, FRCPsych is a Nigerian psychiatrist. He served as Alumni Professor and Chairman of the Department of Psychiatry and Neurobehavioral Sciences at the University of Virginia and is known for his research into addiction.
David M. McDowell (1963–2014) was an American psychiatrist, author and creative consultant. He co-founded the Substance Treatment and Research Service at Columbia University and served as its medical director. He also founded Columbia's Buprenorphine Program, the first such treatment program for opiate addiction in the United States, which according to The New York Times had an 88% success rate. His scholarly work has focused on co-occurring psychiatric disorders and substance abuse problems, particularly club drugs and marijuana. McDowell's book Substance Abuse: From Principles to Practice, is one of the more highly regarded and accessible books on the subject, and is excerpted in the American Psychiatric Association's textbook on substance abuse treatment.
Herbert David Kleber was an American psychiatrist and substance abuse researcher. His career, centered on the evidence-based treatment of addiction, focused on scientific approaches in place of punishment and moralisms. His career focused on pathology of addiction to help patients reduce the severe discomforts of withdrawal, avoid relapse and stay in recovery.
