Edwin Fuller Torrey (born September 6, 1937), is an American psychiatrist and schizophrenia researcher. He is associate director of research at the Stanley Medical Research Institute[1] (SMRI) and founder of the Treatment Advocacy Center (TAC), a nonprofit organization whose principal activity is promoting the passage and implementation of outpatient commitment laws and civil commitment laws and standards in individual states that allow people diagnosed with severe mental illness to be involuntarily hospitalized and treated throughout the United States.[2][3]
Torrey has conducted numerous research studies, particularly on possible infectious causes of schizophrenia. He has become well known as an advocate of the idea that severe mental illness, psychosis, is due to biological factors and not social factors as may be found in neurotic illnesses.[4] He has appeared on national radio and television outlets and written for many newspapers. He has received two Commendation Medals by the U.S. Public Health Service along with other awards and tributes. He has been criticized by a range of people, including federal researchers and others for some of his attacks on de-institutionalization and his support for forced medication as a method of treatment.[5]
Torrey is on the board of the Treatment Advocacy Center (TAC), which describes itself as being "a national nonprofitadvocacy organization".[6] TAC supports involuntary treatment when deemed appropriate by a judge (at the urging of the person's psychiatrist and family members). Torrey has written several books on mental illness, including Surviving Schizophrenia. He is a distant relative of abolitionistCharles Turner Torrey and has written his biography.
Education and early career
Torrey earned his bachelor's degree from Princeton University, and his M.D. from the McGill University Faculty of Medicine. Torrey also earned a master's degree in anthropology from Stanford University, and was trained in psychiatry at Stanford University School of Medicine. At McGill and later at Stanford, he was exposed to a biological approach and recalls that one of his first-year instructors at McGill was Heinz Lehmann, the first clinician in North America to use the first neuroleptic medication, chlorpromazine.[7]
Torrey practiced general medicine in Ethiopia for two years as a Peace Corps physician followed by practiced in the South Bronx, US. From 1970 to 1975, he was a special administrative assistant to the National Institute of Mental Health director. He then worked for a year in Alaska in the Indian Health Service. He became a ward physician at St. Elizabeths psychiatric hospital in Washington, D.C.[5] for nine years, where he reportedly worked with the most challenging patients and aimed to avoid the use of seclusion or restraints on the acute admission units.[7] He also volunteered at Washington, D.C. homeless clinics.[8]
Stanley Medical Research Institute
Torrey is the founder and executive director of the Stanley Medical Research Institute (SMRI), a large, private entity for conducting research on schizophrenia and bipolar disorder in the U.S. SMRI also maintains a collection of postmortem brain tissue from individuals with schizophrenia, bipolar disorder, and major depression and from unaffected controls, which are made available to researchers without charge.
After reading Torrey's book Surviving Schizophrenia, Theodore Stanley, a businessman who had made a fortune in direct-mail marketing and whose son had been diagnosed in the late 1980s with bipolar disorder, contacted Torrey and he and his wife provided the funds for the new institute.[9]
As of 2004[update] the Stanley Institute had 30 employees and funded half of all U.S. research on bipolar disorder and about a quarter of all schizophrenia research. In 2003 the institute's research budget was around $40 million, 74 percent of which was given out to other researchers through grants.[9] As of 2008 SMRI reported that 75% of its expenditure goes towards the development of new treatments.[10]
The Stanley Medical Institute in Bethesda, Maryland has collected around 600 brains as of 2008[11]
The SMRI has been sued for allegedly taking brains for use in research without proper consent. One lawsuit was settled out of court.[12][13]
SMRI reports that it has a close relationship with and is the supporting organization for the Treatment Advocacy Center (TAC).[10]
Treatment Advocacy Center
Torrey is a founder of the Treatment Advocacy Center, a national organization that supports outpatient commitment for certain people with mental illness who, in his view of their treatment history and present circumstances, are judged unlikely to survive safely in the community without supervision. TAC has been credited by New York State Attorney General Eliot Spitzer and others with helping pass Kendra's Law in the state. Kendra's Law allows court-ordered involuntary treatment of people diagnosed with schizophrenia or other severe mental illness who have a history of not following psychiatric advice, i.e., individuals who are, "as a result of his or her mental illness, unlikely to voluntarily participate in the recommended treatment pursuant to the treatment plan."[14] Previously, only inpatient programs were available to submit a person to involuntary treatment. TAC's efforts to pass Kendra's Law led to similar successful passage of Laura's Law in California, and similar laws in Florida and elsewhere.
National Alliance on Mental Illness
Torrey was for many years an active advisor for the National Alliance on Mental Illness (NAMI). Parents felt that he spoke up for them when much of the medical establishment had previously held that parenting was responsible for schizophrenia. Torrey helped build NAMI into a powerful political force through campaigning and donating the hardcover royalties from the sale of his book Surviving Schizophrenia.[8]
Although Torrey, TAC, and NAMI remain aligned, NAMI may have tried to distance itself from TAC in 1998. One source The Psychiatric Times, reported that TAC was designed from the start to be "a separate support organization with its own source of funding."[15] According to MindFreedom International, an association of survivors of psychiatric treatment opposed to involuntary treatment, NAMI severed its relationship with TAC because of pressure from groups opposed to Torrey both from within NAMI and outside NAMI. Torrey is, according to MindFreedom, one of "the most feverishly pro-force psychiatrists in the world". MindFreedom suggests that the "links between NAMI and TAC are simply going from overt to covert."[16]
In 2002, NAMI's Executive Director issued a statement highly critical of 60 Minutes for producing a piece entitled "Dr. Torrey's War." In the statement, NAMI alternately criticized and backed various positions espoused by Torrey while aiming its criticism at 60 Minutes for what NAMI called "sound bite journalism."[17]
Torrey was also the keynote speaker at the 23rd annual NAMI convention in 2002.[18]
In 2005, NAMI gave Torrey a tribute on its 25th Anniversary Celebratory Donor Wall, for those who have donated over $25,000. It called him a groundbreaking researcher, a ferociously resolute advocate, a prominent and admired author of dozens of books and a dedicated practicing clinician, and said that he had "touched the lives of countless NAMI members throughout this nation."[19]
NAMI has some continuing links to TAC via their board of directors. Frederick Frese, a psychologist who died in 2018, was on both the NAMI and TAC boards. TAC has two other former NAMI board members on their board and Laurie Flynn, the former NAMI executive director, is part of the TAC Honorary Advisory Committee.[citation needed]
In 2008, Torrey disagreed with a NAMI view on second-generation antipsychotics and accused the medical director and executive director of failing to disclose conflicts of interest, because they are employees of an organization that receives more than half its budget from pharmaceutical companies. He argued they were not representing the views of many members of NAMI including himself.[20]
Scientific research and views
In the 1950s, it was commonly thought that schizophrenia was caused by bad parenting. Torrey has argued that this theory had a toxic effect on parents. His sister had severe schizophrenia and spent most of five decades in hospitals and nursing homes until her death.[7]
Torrey has been a fierce opponent of the influence of Sigmund Freud and psychoanalysis. He has also argued that psychiatry should focus only on severe mental illness, conceived as neurological disorders, rather than other mental issues that he viewed as non-medical.[21][22]
Torrey was principal investigator of a NIMH Schizophrenia/Bipolar Disorder Twin Study conducted at the Neuroscience center of St Elizabeth's Hospital in the late 1980s/early 1990s, and copublished more than a dozen studies on structural brain differences between affected and unaffected siblings.[7] He differed from his collaborators in arguing that the genetic heritability of schizophrenia was lower than typically estimated.[21][23] A review of Torrey's data analysis, however, suggested he had erroneously compared different sorts of concordance statistics.[24]
In the early 1970s, Torrey became interested in viral infections as possible causes of schizophrenia[25] or bipolar disorder, particularly a parasite Toxoplasma gondii whose definitive host is the cat, but whose intermediate host can be any mammal, including humans.[21] Up to one third of the world's human population is estimated to carry a Toxoplasma infection.[26] Since then he has published, often with Robert Yolken, more than 30 articles on seasonal variation and possible infectious causes of schizophrenia, focusing especially on Toxoplasma gondii. He is involved in five or six ongoing studies using anti-Toxoplasmosa gondii agents (e.g. antibiotics such as minocycline and azithromycin[27][28]) as an add-on treatment for schizophrenia. He believes that infectious causes will eventually explain the "vast majority" of schizophrenia cases.[7] Some of his collaborators have disagreed with the emphasis he has placed on infection as a direct causal factor.[21] Many of the research studies on links between schizophrenia and Toxoplasma gondii, by different authors in different countries, are funded and supported by the Stanley Medical Research Institute. The hypothesis is not prominent in current mainstream scientific views on the causes of schizophrenia, although infections may be seen as one possible risk factor that could lead to vulnerabilities in early neurodevelopment in some cases.[citation needed] Torrey hopes to live long enough to see vaccines to prevent many or most cases of schizophrenia.[7]
Torrey has generally been in favor of antipsychotic drugs. He has claimed that taking antipsychotics reduces the risk of violence, homelessness and prison. He has argued that "noncompliance" in about half of cases of schizophrenia and bipolar disorder is due to lack of "insight" into the illness because the part of the brain for self-awareness has been affected; and that in some who are aware it is due to adverse effects ranging from tremors or sedation to sexual dysfunction to substantial weight gain.[29] He has also reported that at least some antipsychotics cause medical conditions that can be fatal in some people, especially African Americans.[30] He has also argued that pharmaceutical companies have too much influence over psychiatric organizations and psychiatrists, effectively buying them off.[31]
Torrey has appeared on national radio and television (outlets like NPR, Oprah, 20/20, 60 Minutes, and Dateline) and has written for many newspapers. He has received a 1984 Special Families Award from NAMI, two Commendation Medals from the U.S. Public Health Service, a 1991 National Caring Award, and a humanitarian award from NARSAD (now known as the Brain & Behavior Research Foundation). In 1999, he received a research award from the International Congress of Schizophrenia. In 2005, a tribute to Torrey was included in NAMI's 25th Anniversary Celebratory Donor Wall.[33]
Criticism
Torrey has criticized many organizations. He has charged the National Institute of Mental Health with not concentrating its resources sufficiently on severe mental illness and directly applicable research; NIMH has disputed his statistics and viewpoint.[34]
Experts such as Dr. Peter C. Gøtzsche, Dr. Jorun Rugkåsa, James Gottstein, and others have called into question both the evidence basis and ethics of coercive practices such as court-ordered treatment, citing substantial scientific literature and patient testimony showing harm and/or lack of benefit.[35][36][37][38] The United Nations and its World Health Organization have repeatedly called for the end to coercive interventions in psychiatry, naming them as human rights violations traumatizing significant portions of those affected; instead, they suggest community-based alternatives without threat of force.[39][36][40][41]
Torrey has been charged with acting to limit the voice of those consumers, survivors and ex-patients that he disagrees with, opposing their civil rights and censoring and ridiculing their ideas and those of their supporters. Torrey has been a long-time critic of the Center for Mental Health Services that provides support and advocacy, on the grounds that they support anti-psychiatry groups and those opposed to outpatient commitment, claiming they neglect the seriously mentally ill due to a hippie '60s attitude, distribute funds on the basis of other factors such as "community cohesion" and ethnic minority involvement, and are more dysfunctional than the individuals they are supposed to help.[42] He has specifically opposed public funding for the National Empowerment Center, for rejecting the medical model and arguing for a recovery model without necessarily needing medication; it has since lost its funding from the CMHS. Torrey has in general been instrumental in lobbying against, and undermining, community-based consumer projects because they promoted social and experiential recovery and questioned the standard medical model. Consumer organizations have protested that they are already economically disadvantaged and vulnerable to political whim while Torrey and his organizations have rich and powerful backers.[32] It has been argued that Torrey and other psychiatric and family member advocates do not necessarily have the same interests as consumers/survivors themselves. Differences in ideology sharpened after the development of NAMI.[43]
In criticizing the New Freedom Commission on Mental Health for not recommending forced outpatient medicating, Torrey claimed that stigma against people with mental disorders was largely due to them committing violent acts due to not taking medication. He called the recovery model harmful for sending a cruel message of hope, or implicit blame, to those he believes cannot engage in a recovery process, despite being a laudable long-term vision for the commission.[32][44] However, there is no current evidence that forcing psychiatric drug compliance reduces risk of crime. Furthermore, evidence suggests that using antipsychotic medication may not reduce risk of homicide, and use of other popular psychiatric drugs may increase risk (based on causal inference after controlling for confounding factors related to taking medication).[45]
Although Torrey described family members as "surviving schizophrenia" in his book of that title, in 1997 he said the term "psychiatric survivor" used by ex-patients to describe themselves was just political correctness and he blamed them, along with civil rights lawyers, for the deaths of half a million people due to suicides and deaths on the street.[46] His comments elicited a record number of letters in response, some in favour of Torrey but most against.[47] The accusations have been described as inflammatory and completely unsubstantiated, and issues of self-determination and self-identity said to be more complex than Torrey realizes.[47] In the same journal in 1999, Torrey and Miller of the Stanley Foundation Research Program argued for an incentivised schizophrenia treatment system backed by a credible threat of force, modeled on that used for the fatal infectious disease tuberculosis;[48] replies criticized the logic of the analogy and resort to forced drugging rather than developing alliances and understanding, to which Torrey accused the director and members of MindFreedom International of living off federal funds while denying illness and not caring about the mentally ill on the streets and in prisons.[49][50]
Torrey has been a vocal critic of the failures of deinstitutionalization and inadequate community mental health services. He has generally linked this to issues of violence, homelessness and medication noncompliance, as well as lack of proper focus by the relevant governmental organizations.[51] He has been accused of gaining influence by sensationalizing and exaggerating the incidence of violence and its link to medication noncompliance, including disseminating unsubstantiated and unreliable statistics. When a California NAMI journal editor included a questioning of Torrey's statistics, the local board glued together the pages and effectively shut down the journal.[32][52] Others, while agreeing that public mental health care in the U.S. falls far short of what people with serious psychiatric disorders need and deserve, have argued that Torrey's solutions are outdated and that his book The Insanity Offense is based on unsubstantiated portrayals of certainty on the statistics on violence, outpatient commitment and medication, stigmatizing tens of thousands of people, deeply offending and insulting those who hold views differing from his own, and promulgating one-dimensional solutions. TAC's attempts to associate violent incidents in the news with lack of medication have been described as wild hyperbole, and the use of the term "assisted treatment" has been described as a euphemism for forced drugging.[53]
Torrey has been criticized by, and has criticized, Thomas Szasz, a libertarian psychiatrist and author of The Myth of Mental Illness (1961), who is opposed to involuntary treatment.[54][55] Torrey has said he admires Szasz for his outspoken criticisms of many psychiatric practices, including "diagnostic creep" (disease mongering) and the potential for the political abuse of psychiatric labels, but he has criticized Szasz for asserting that schizophrenia is not an organic disease of the brain like, for example, Parkinson's disease or multiple sclerosis.

A mental disorder, also referred to as a mental illness, a mental health condition, or a psychiatric disorder, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. A mental disorder is also characterized by a clinically significant disturbance in an individual's cognition, emotional regulation, or behavior, often in a social context. Such disturbances may occur as single episodes, may be persistent, or may be relapsing–remitting. There are many different types of mental disorders, with signs and symptoms that vary widely between specific disorders. A mental disorder is one aspect of mental health.
Psychiatric hospitals, also known as mental health hospitals, or behavioral health hospitals are hospitals or wards specializing in the treatment of severe mental disorders, including schizophrenia, bipolar disorder, eating disorders, dissociative identity disorder, major depressive disorder, and others.
Anti-psychiatry, sometimes spelled antipsychiatry without the hyphen, is a movement based on the view that psychiatric treatment is often more damaging than helpful to patients, highlighting controversies about psychiatry. Objections include the reliability of psychiatric diagnosis, the questionable effectiveness and harm associated with psychiatric medications, the failure of psychiatry to demonstrate any disease treatment mechanism for psychiatric medication effects, and legal concerns about equal human rights and civil freedom being nullified by the presence of diagnosis. Historical critiques of psychiatry came to light after focus on the extreme harms associated with electroconvulsive therapy or insulin shock therapy. The term "anti-psychiatry" is in dispute and often used to dismiss all critics of psychiatry, many of whom agree that a specialized role of helper for people in emotional distress may at times be appropriate, and allow for individual choice around treatment decisions.
Schizoaffective disorder is a mental disorder characterized by abnormal thought processes and an unstable mood. This diagnosis requires symptoms of both schizophrenia and a mood disorder: either bipolar disorder or depression. The main criterion is the presence of psychotic symptoms for at least two weeks without any mood symptoms. Schizoaffective disorder can often be misdiagnosed when the correct diagnosis may be psychotic depression, bipolar I disorder, schizophreniform disorder, or schizophrenia. This is a problem as treatment and prognosis differ greatly for most of these diagnoses.
The National Alliance on Mental Illness (NAMI) is a United States-based nonprofit organization originally founded as a grassroots group by family members of people diagnosed with mental illness. NAMI identifies its mission as "providing advocacy, education, support and public awareness so that all individuals and families affected by mental illness can build better lives" and its vision as "a world where all people affected by mental illness live healthy, fulfilling lives supported by a community that cares". NAMI offers classes and trainings for people living with mental illnesses, their families, community members, and professionals, including what is termed psychoeducation, or education about mental illness. NAMI holds regular events which combine fundraising for the organization and education, including Mental Illness Awareness Week and NAMIWalks.
Biological psychiatry or biopsychiatry is an approach to psychiatry that aims to understand mental disorder in terms of the biological function of the nervous system. It is interdisciplinary in its approach and draws on sciences such as neuroscience, psychopharmacology, biochemistry, genetics, epigenetics and physiology to investigate the biological bases of behavior and psychopathology. Biopsychiatry is the branch of medicine which deals with the study of the biological function of the nervous system in mental disorders.
The Treatment Advocacy Center (TAC) is a U.S. non-profit organization based in Arlington, Virginia, originally announced as the NAMI Treatment Action Centre in 1997. The TAC was subsequently directed by psychiatrist E. Fuller Torrey and identifies its mission as "dedicated to eliminating barriers to the timely and effective treatment of severe mental illness". The organization is most well-known for proposed laws, policies, and practices regarding legally compelled outpatient services or outpatient commitment for people diagnosed with mental illness. The organization identifies its other key issues as "anosognosia, consequences of non-treatment, criminalization of mental illness, psychiatric bed shortages, public service costs, violence and mental illness". Advocates for mental health have criticized TAC for endorsing coercion and forced treatment.
Deinstitutionalisation is the process of replacing long-stay psychiatric hospitals with less isolated community mental health services for those diagnosed with a mental disorder or developmental disability. In the late 20th century, it led to the closure of many psychiatric hospitals, as patients were increasingly cared for at home, in halfway houses and clinics, in regular hospitals, or not at all.
The biopsychiatry controversy is a dispute over which viewpoint should predominate and form a basis of psychiatric theory and practice. The debate is a criticism of a claimed strict biological view of psychiatric thinking. Its critics include disparate groups such as the antipsychiatry movement and some academics.
The psychiatric survivors movement is a diverse association of individuals who either currently access mental health services, or who have experienced interventions by psychiatry they consider unhelpful, harmful, abusive or illegal.

The National Empowerment Center (NEC) is an advocacy and peer-support organization in the United States that promotes an empowerment-based recovery model of mental disorders. It is run by consumers/survivors/ex-patients "in recovery" and is located in Lawrence, Massachusetts in Essex County.
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.
Jeffrey Alan Lieberman is an American psychiatrist who specializes in schizophrenia and related psychoses and their associated neuroscience (biology) and pharmacological treatment. He was principal investigator for CATIE, the largest and longest independent study ever funded by the United States National Institute of Mental Health to examine existing pharmacotherapies for schizophrenia. He was president of the American Psychiatric Association from May 2013 to May 2014.
Depression, one of the most commonly diagnosed psychiatric disorders, is being diagnosed in increasing numbers in various segments of the population worldwide. Depression in the United States alone affects 17.6 million Americans each year or 1 in 6 people. Depressed patients are at increased risk of type 2 diabetes, cardiovascular disease and suicide. Within the next twenty years depression is expected to become the second leading cause of disability worldwide and the leading cause in high-income nations, including the United States. In approximately 75% of suicides, the individuals had seen a physician within the prior year before their death, 45–66% within the prior month. About a third of those who died by suicide had contact with mental health services in the prior year, a fifth within the preceding month.
Allen J. Frances is an American psychiatrist. He is currently Professor and Chairman Emeritus of the Department of Psychiatry and Behavioral Sciences at Duke University School of Medicine. He is best known for serving as chair of the American Psychiatric Association task force overseeing the development and revision of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Frances is the founding editor of two well-known psychiatric journals: the Journal of Personality Disorders and the Journal of Psychiatric Practice.
The following outline is provided as an overview of and topical guide to psychiatry:
Psychiatry is, and has historically been, viewed as controversial by those under its care, as well as sociologists and psychiatrists themselves. There are a variety of reasons cited for this controversy, including the subjectivity of diagnosis, the use of diagnosis and treatment for social and political control including detaining citizens and treating them without consent, the side effects of treatments such as electroconvulsive therapy, antipsychotics and historical procedures like the lobotomy and other forms of psychosurgery or insulin shock therapy, and the history of racism within the profession in the United States.
Augustus John Rush is an internationally renowned psychiatrist. He is a professor emeritus in Duke-NUS Medical School at the National University of Singapore (NUS), and adjunct professor of psychiatry and behavioral sciences at Duke University School of Medicine. He has authored and edited more than 10 books, and over 600 scientific journal articles that are largely focused on the diagnosis and treatment of depressive and bipolar disorders.
Lori Altshuler was a professor at the University of California, Los Angeles (UCLA) Department of Psychiatry and Biobehavioral Sciences and held the Julia S. Gouw Endowed Chair for Mood Disorders. Altshuler was the Director of the UCLA Mood Disorders Research Program and the UCLA Women's Life Center, each being part of the Neuropsychiatric Hospital at UCLA.
