theme of the gay liberation, anti-psychiatry, and feminist movements of the 1970s, but now there is actually no resistance to the advance of government intrusion in lifestyle if it is thought to be justified in terms of public health. in the opinion of mike fitzpatrick, the pressure for medicalization also comes from society itself. as one example, fitzpatrick claims that feminists who once opposed state intervention as oppressive and patriarchal, now demand more coercive and intrusive measures to deal with child abuse and domestic violence. according to richard gosden, the use of psychiatry as a tool of social control is becoming obvious in preventive medicine programmes for various mental diseases.: 14 these programmes are intended to identify children and young people with divergent behavioral patterns and thinking and send them to treatment before their supposed mental diseases develop.: 14 clinical guidelines for best practice in australia include the risk factors and signs which can be used to detect young people who are in need of prophylactic drug treatment to prevent the development of schizophrenia and other psychotic conditions.: 14 psychiatry and the pharmaceutical industry critics of psychiatry commonly express a concern that the path of diagnosis and treatment in contemporary society is primarily or overwhelmingly shaped by profit prerogatives, echoing a common criticism of general medical practice in the united states, where many of the largest psychopharmaceutical producers are based. psychiatric research has demonstrated varying degrees of efficacy for improving or managing a number of mental health disorders through either medications, psychotherapy, or a combination of the two. typical psychiatric medications include stimulants, antidepressants, anxiolytics, and antipsychotics (neuroleptics). on the other hand, organizations such as mindfreedom international and world network of users and survivors of psychiatry maintain that psychiatrists exaggerate the evidence of medication and minimize the evidence of adverse drug reaction. they and other activists believe individuals are not given balanced information, and that current psychiatric medications do not appear to be specific to particular disorders in the way mainstream psychiatry asserts; and psychiatric drugs not only fail to correct measurable chemical imbalances in the brain, but rather induce undesirable side effects. for example, though children on ritalin and other psycho-stimulants become more obedient to parents and teachers, critics have noted that they can also develop abnormal movements such as tics, spasms and other involuntary movements. this has not been shown to be directly related to the therapeutic use of stimulants, but to neuroleptics. the diagnosis of attention deficit hyperactivity disorder on the basis of inattention to compulsory schooling also raises critics' concerns regarding the use of psychoactive drugs as a means of unjust social control of children. the influence of pharmaceutical companies is another major issue for the anti-psychiatry movement. as many critics from within and outside of psychiatry have argued, there are many financial and professional links between psychiatry, regulators, and pharmaceutical companies. drug companies routinely fund much of the research conducted by psychiatrists, advertise medication in psychiatric journals and conferences, fund psychiatric and healthcare organizations and health promotion campaigns, and send representatives to lobby general physicians and politicians. peter breggin, sharkey, and other investigators of the psycho-pharmaceutical industry maintain that many psychiatrists are members, shareholders or special advisors to pharmaceutical or associated regulatory organizations. there is evidence that research findings and the prescribing of drugs are influenced as a result. a united kingdom cross-party parliamentary inquiry into the influence of the pharmaceutical industry in 2005 concludes: "the influence of the pharmaceutical industry is such that it dominates clinical practice" and that there are serious regulatory failings resulting in "the unsafe use of drugs; and the increasing medicalization of society". the campaign organization no free lunch details the prevalent acceptance by medical professionals of free gifts from pharmaceutical companies and the effect on psychiatric practice. the ghostwriting of articles by pharmaceutical company officials, which are then presented by esteemed psychiatrists, has also been highlighted. systematic reviews have found that trials of psychiatric drugs that are conducted with pharmaceutical funding are several times more likely to report positive findings than studies without such funding. the number of psychiatric drug prescriptions have been increasing at an extremely high rate since the 1950s and show no sign of abating. in the united states antidepressants and tranquilizers are now the top selling class of prescription drugs, and neuroleptics and other psychiatric drugs also rank near the top, all with expanding sales. as a solution to the apparent conflict of interests, critics propose legislation to separate the pharmaceutical industry from the psychiatric profession. john read and bruce e. levine have advanced the idea of socioeconomic status as a significant factor in the development and prevention of mental disorders such as schizophrenia and have noted the reach of pharmaceutical companies through industry sponsored websites as promoting a more biological approach to mental disorders, rather than a comprehensive biological, psychological and social model. electroconvulsive therapy main article: electroconvulsive therapy a bergonic chair "for giving general electric treatment for psychological effect, in psycho-neurotic cases", according to original photo description. world war i era. psychiatrists may advocate psychiatric drugs, psychotherapy or more controversial interventions such as electroshock or psychosurgery to treat mental illness. electroconvulsive therapy (ect) is administered worldwide typically for severe mental disorders. across the globe it has been estimated that approximately 1 million patients receive ect per year. exact numbers of how many persons per year have ect in the united states are unknown due to the variability of settings and treatment. researchers' estimates generally range from 100,000 to 200,000 persons per year. some persons receiving ect die during the procedure (ect is performed under a general anaesthetic, which always carries a risk). leonard roy frank writes that estimates of ect-related death rates vary widely. the lower estimates include: 2–4 in 100,000 (from kramer's 1994 study of 28,437 patients) 1 in 10,000 (boodman's first entry in 1996) 1 in 1,000 (impastato's first entry in 1957) 1 in 200, among the elderly, over 60 (impastato's in 1957) higher estimates include: 1 in 102 (martin's entry in 1949) 1 in 95 (boodman's first entry in 1996) 1 in 92 (freeman and kendell's entry in 1976) 1 in 89 (sagebiel's in 1961) 1 in 69 (gralnick's in 1946) 1 in 63, among a group undergoing intensive ect (perry's in 1963–1979) 1 in 38 (ehrenberg's in 1955) 1 in 30 (kurland's in 1959) 1 in 9, among a group undergoing intensive ect (weil's in 1949) 1 in 4, among the very elderly, over 80 (kroessler and fogel's in 1974–1986). political abuse of psychiatry main article: political abuse of psychiatry
