Schizophrenia is a serious disorder which affects how a person thinks, feels and acts. Someone with schizophrenia may have difficulty distinguishing between what is real and what is imaginary; may be unresponsive or withdrawn; and may have difficulty expressing normal emotions in social situations. Contrary to public perception, schizophrenia is not split personality or multiple personality. The vast majority of people with schizophrenia are not violent and do not pose a danger to others. Schizophrenia is not caused by childhood experiences, poor parenting or lack of willpower, nor are the symptoms identical for each person. After noting that one percent of the world's population suffers from this disability and describing its symptoms, experts discuss how this insidious disease affects the human brain and a person's ability to function socially. Fortunately, some afflicted individuals are able to achieve a high state of functioning, including Dr. John Nash Jr., who won a Nobel Prize in Economics. However, most spend their lives struggling to cope with hallucinatory voices and the potent drugs designed to control all of the troubling symptoms of the illness. Case studies and interviews help illustrate how various people are trying to live with this disease.
The signs of schizophrenia are different for everyone. Symptoms may develop slowly over months or years, or may appear very abruptly. The disease may come and go in cycles of relapse and remission.
Behaviors that are early warning signs of schizophrenia include:
- Hearing or seeing something that isn’t there
- A constant feeling of being watched
- Peculiar or nonsensical way of speaking or writing
- Strange body positioning
- Feeling indifferent to very important situations
- Deterioration of academic or work performance
- A change in personal hygiene and appearance
- A change in personality
- Increasing withdrawal from social situations
- Irrational, angry or fearful response to loved ones
- Inability to sleep or concentrate
- Inappropriate or bizarre behavior
- Extreme preoccupation with religion or the occult
Schizophrenia affects about 1% of the world population. In the United States one in a hundred people, about 2.5 million, have this disease. It knows no racial, cultural or economic boundaries. Symptoms usually appear between the ages of 13 and 25, but often appear earlier in males than females. If you or a loved one experience several of these symptoms for more than two weeks, seek help immediately.
Psychiatry under attack –inside and out
Psychiatry has always been controversial – there never was an extended ‘Golden Age’ of peace and tranquility when everyone was in agreement. You probably read these texts after some heated discussion about the rights and wrongs of something psychiatrists do. Because it deals with the mind, and because psychiatrists can act against our wishes, it will always generate a degree of suspicion and fear. And it isn’t good enough simply to put this down to ignorance and say that if people knew more they wouldn’t have such concerns. There are very real questions to be asked about psychiatry – both about its legitimacy, its status as ‘just another medical specialty’, and also about how it is practised. The power of modern medicine invariably brings ethical challenges and controversies and psychiatry has its fair share. These will be taken up more in later. This text will focus on the contradictions and tensions which are inherent in psychiatry that stem from its very nature, rather than problems with practice.
The French philosopher René Descartes (1596-1650) is often blamed for how we distinguish between the mind and the body in Western thought (often referred to as ‘Cartesian dualism’). His ‘cogito ergo sum’ (‘I think therefore I am’) is snappy and memorable; it expresses his scepticism about certainty in knowing about the material world. It is hard to understand why he has been singled out for all the ‘blame’ for an issue which exercised most of his empiricist philosopher contemporaries. He didn’t invent the problem of the mind; he simply put some of the issues better and they remain essentially unresolved 350 years later. What the mind is, and how it interacts with the material world, still remain mysteries. Most of us do think there is a difference and most of us accept that there is an interaction. We have to live our lives believing we can directly influence the material world (e.g. I decide to stretch out my arm and expect to turn on the computer). We also need to believe that we can know the minds of others (e.g. I’m sure that you will go to the library or hand in your essay). Without these beliefs we would effectively be paralysed.
The mind–body question is unavoidable in psychiatry. The relationship between the mind and the brain is the big issue. It would be simple if psychiatry were just about ‘brain diseases’ in the way that nephrology is about kidney diseases or cardiology is about heart diseases. Psychiatry, however, is concerned with ‘mental’ illnesses. We know that many mental illnesses involve disorders of the brain (e.g. disturbances in transmitter chemicals between cells in depression and schizophrenia) but not all brain diseases are mental illnesses or the responsibility of psychiatrists. Multiple sclerosis and Parkinson’s disease are both undeniably brain diseases but it is neurologists, not psychiatrists, who deal with them. These neurological disorders often cause psychiatric problems, just as a wide range of physical disorders can. Many psychiatric disorders include physical symptoms (e.g. tiredness and pain), just as physical disorders include psychiatric symptoms (e.g. depression, anxiety, and even hallucinations).
Psychiatric disorders are those where the main disturbances are in thoughts, feelings, and behaviour. Physical diseases don’t just have physical causes and cures and mental diseases have mental causes and cures. Illnesses can have physical causes and even physical cures (e.g. a depression caused entirely by Parkinson’s disease which is effectively treated by antidepressant tablets) and still be ‘mental illnesses’. The division is based on the main disturbance and on the skills needed to help the patient. ‘Mental disorders are brain disorders’ has been a popular slogan with some psychiatrists and patient groups. Its purpose is to emphasize the similarity between mental and physical illnesses, reducing stigma and blame. These are admirable goals but it is an oversimplification.
Psychiatry has to struggle with an ambiguity fought out on two main battlegrounds.
Nature versus nurture: do families cause mental illness?
Whether you’re tall or short, whether you’re good at sport or hopeless, most of us believe this depends on a mixture of our genes (the biological potential we were born with) and our upbringing (our diet, exercise regime, even the sort of school we went to). Nothing controversial in that. The moment we mention psychology, however, the balloon goes up. Is IQ inherited or could everyone do just as well with the same opportunities? Is personality or criminality something we’re born with or can we change it? Can we avoid depression by healthy living? Few issues polarize us as much as how changeable we believe human behaviour to be. The disagreements are not just calm, academic ones but fuel (and are fueled by) political and social beliefs reflecting fundamentally different worldviews.
Psychiatry originally was very much at home in the ‘nature’ camp – mental illnesses ran in families and were inherited weaknesses. It was our job to ameliorate them and make life as bearable as possible, hoping for a speedy recovery. Freud and his followers began to change all that, shifting the balance to ‘nurture’. Psychoanalysis is firmly based on the belief that what happens to us in early life, and the memory of those experiences, is the cause of many illnesses. Even more convincing, Freud showed that addressing those memories could cure some mental illnesses. So an individual’s personal history (their ‘narrative’) wasn’t just the context for understanding their illness but possibly its origin.
Psychoanalysis dominated psychiatric thinking and training from the 1940s to the 1970s. The attraction of psychoanalysis to the
An attraction of emphasizing nurture is that it holds out much greater possibility of cure. If mental illnesses are essentially caused by relationships then they should be curable by relationships (i.e. psychotherapy). However, the downside of this approach is its potential for blame – in particular blaming parents. Freud himself quickly realized these risks when he began to suspect that the reported sexual abuse by parents (which he originally considered the cause of his patients’ neuroses) might be fantasies. The great German psycho pathologist and philosopher Jaspers pointed out that, while understanding the personal relevance of symptoms was essential in psychiatry, it was not the same as understanding what caused the illness. Such fine distinctions have not, however, generally characterized this debate publicly.
The origins of schizophrenia
This controversy has raged most fiercely over the origins of schizophrenia. Schizophrenia had always been known to run in families and it had been observed that these families could seem ‘odd’ (eccentric or withdrawn), often with strained or intensely over-involved relationships. As schizophrenia is a disorder expressed in thinking and relating there is an obvious possible link between it and early upbringing. Family life is, after all, conducted through thinking and relating and aims to equip the growing child with skills in these areas. As psychoanalytical thinking was applied to schizophrenia (something that Freud explicitly avoided) a number of theories were proposed, some of which had enormous influence and have entered the language.
The ‘schizophrenogenic mother’
The most notorious (and probably the most damaging) of these was that of the cold, hostile, and yet controlling parent – the ‘schizophrenogenic mother’ (literally ‘schizophrenia-causing mother’). This was proposed by the analyst Frieda Fromm-Reichmann who, along with Harry Stack Sullivan, engaged in long-term intensive psychoanalysis with hospitalized schizophrenia patients in the
The anthropologist Gregory Bateson proposed that persistent, logically faulty, and contradictory communication with a child prevented it forming a proper sense of itself and its relationships to the external world. Bateson was influenced by Bertrand Russell and A. N. Whitehead’s mathematical writings. One of their proposals was that the number which designated a series of numbers could not itself be a member of that series – as the designating number was of a ‘logically different order’. Bateson said that there were similarly logically different levels of communication and that we sent messages to each other (often in an oblique manner) where one part of the message indicated how the main part should be understood. He called these oblique messages ‘meta-communications’ (i.e. Communications about communication). Typically meta-communications were emotional and non-verbal and became family assumptions (e.g. ‘mother can only love her children and always feel positive about them’).
Bateson called it a double-bind when the non-verbal message and verbal message contradicted each other (e.g. an obviously angry mother saying she didn’t mind at all that the child had broken a glass and holding her arms out for an embrace). A double-bind required three components: a clear simple message, a contradictory meta-communication, and an absolute ban on the contradiction being acknowledged. All three were necessary but it was probably the family culture of denying the contradiction that was most pathological. After all, all families give contradictory and confusing messages. The term ‘double-bind’ is now used loosely to imply any contradictory communication but Bateson’s theory was much more precise.
These theories have all been conclusively demolished by careful scientific examination. One approach was to get independent researchers to listen to tapes of families with and without schizophrenia and rate the occurrence of double-binds, or to interview families and rate them for coldness, hostility, over involvement, etc. Reliable differences were simply not found. Adoption studies, however, delivered the coup de grace. Very rigorous studies of children adopted away at birth to healthy families found rates of schizophrenia when they grew up just as high as if they had been brought up with their schizophrenic mother. Similarly twins adopted away at birth to different families demonstrated the same difference in rates between identical and non-identical twins found in those brought up in their natural families. None of these risks are 100 per cent and clearly upbringing and environment have quite a lot of influence.
While family influence as the cause of schizophrenia has been conclusively dismissed it remains implicated in the course of the illness. Individuals with schizophrenia in highly emotionally charged families are likely to break down more often. This could, of course, be because families with more severely ill members are more stressful. However, training families to respond less emotionally does reduce the rate of breakdown, so high expressed emotion probably does have an effect.
Social and peer-group pressure
While family influence has been questioned, wider social influences have received increasing recognition in the last half century. For example, the rise in eating disorders (anorexia nervosa and bulimia) has spread from the West, closely tracking the cultural ideal of thinness in women. The epidemic of self-harm (particularly overdosing and cutting in younger women) is clearly affected by group norms and expectations. Local outbreaks can often be linked to specific events such as suicide attempts in TV soap operas. Alcohol and drug use are highly variable between different cultural groups (both between and within nations) and the power of group expectations on such behaviours is undeniable. These are enormously important public health issues and the status of these behaviours as ‘mental illnesses’ will be picked up again in later.
The fading relevance of the nature–nurture argument has recently been revived by the rise of evolutionary psychology. A more sophisticated understanding of Darwinian evolution (survival of the fittest) has led to theories about the possible evolutionary value of some psychiatric disorders. A simplistic view would predict that all mental illnesses with a genetic component should lower survival and ought to die out. ‘Inclusive fitness’, however, assesses the evolutionary value of a characteristic not simply on whether it helps that individual to survive but whether it makes it more likely that their offspring will survive. Richard Dawkins’s 1976 book The Selfish Gene gives convincing explanations of the evolutionary advantages of group support and altruism when individuals sacrifice themselves for others.
A range of speculative hypotheses have since been proposed for the evolutionary advantage of various behaviour differences and mental illnesses. Many of these draw on ethological games-theory (i.e. The benefits of any behaviour can only be understood in the context of the behaviour of other members of the group). So depression might be seen as a safe response to ‘defeat’ in a hierarchical group because it makes the individual withdraw from conflict while they recover.
Mania, conversely, with its expansiveness and increased sexual activity, is proposed as a response to success in a hierarchical tussle promoting the propagation of that individual’s genes. Changes in behaviour that look like depression and hypomania can be clearly seen in primates as they move up and down the pecking order that dominates their lives.
The habitual isolation and limited need for social contact of individuals with schizophrenia has been rather imaginatively proposed as adaptive to remote habitats with low food supplies (and also a protection against the risk of infectious diseases and epidemics). Evolutionary psychology will undoubtedly increasingly influence psychiatric thinking – many of our disorders fit poorly into a classical ‘medical model’. Already it has helped establish a less either–or approach to the discussion. It is, however, a highly controversial area – not so much around mental disorders but in relation to social behaviour and particularly to gender specific behaviour. Here it is often interpreted as excusing a very male-orientated, exploitative worldview. Luckily that is someone else battle.
Why do families blame themselves?
If so many of the family theories have been discredited why spend so much time on the issue here? Family theories in mental illness continue to exercise a remarkably powerful hold over us despite the evidence. And not just in schizophrenia but in depression, anorexia nervosa, personality disorder, drug and alcohol abuse, etc.
Parents seem to have an endless capacity to blame themselves for what happens to their children (and perhaps children to blame their parents). This is probably because we need to believe it. Just as we need to believe in free will and our influence on the outside world, family members need to believe that they influence each other. If we didn’t why would we bother? The evolutionary psychologists would say that parents need to believe it to invest years and years bringing up their children. We’re biologically programmed to look after our children so we need some belief system to support it (just as they might say we’re biologically programmed to mate and need to believe in love to support it). It is proposed that such a belief is a mechanism for sustaining our attention to our biological task.
The downside is, of course, guilt and blame. If we believe we have an influence we feel we have failed if things do not work out well. It is inescapable. Even in expressed emotion work where therapists insist emphatically that no one is to blame and that the aim is solely to find more effective coping strategies, families do feel blamed. ‘If only we weren’t so over-involved he would not have so many relapses.’ ‘Other families must have dealt with it better otherwise how would the therapist know what to advise?’ For some families feeling responsible, despite the guilt, is preferable. It implies the logical consequence that there must be something they can do to influence the outcome.
Cultures which value resignation are less likely to blame themselves (high expressed emotion is less common in
The anti-psychiatry movement
Arguments over mind and brain and nature and nurture have always been part of psychiatry and are likely to remain so. They supported the most sustained and celebrated ‘external’ onslaught on psychiatry. This occurred during the 1960s and 1970s in what came to be called the ‘anti-psychiatry movement’. The mental hospital scandals of the early 1960s and publication of Erving Goffman’s Asylums had prepared the ground for a devastating attack. This was not to be a criticism of some of psychiatry’s practices or of failures in the system; this was to be an assault on the very legitimacy of psychiatry.The anti-psychiatry message was that psychiatry did not so much need improving as scrapping. At its best it was confused and confusing and at its worst a truly evil instrument of oppression masquerading as a benign medical practice. Three charismatic authors came to personify the movement. Two were practising psychiatrists. Their books became campus bibles in the late 1960s and the 1970s at a time of widespread student unrest and they were hugely influential in the

Michel Foucault was a French philosopher who believed that the concept of mental illness was an aberration of the post-Enlightenment age. He objected to the classification of identities, arguing that the existence of madness did not entail the identity of madman. His book Madness and Civilisation challenged the very basis of psychiatric practice and cast it as repressive and controlling (rather than curing and liberating). His work had enormous influence in Continental Europe (most evident in Basaglia’s reforms in
The most accessible and influential of the anti-psychiatrists was R. D. Laing. A Glaswegian psychoanalyst with a brilliant mind and lucid prose style, he turned the psychiatric world upside down with a series of best-selling books. An original and impulsive man, his views changed throughout his career and like Freud he didn’t feel the need to acknowledge these radical changes or explain them. His first, and most influential book, was The Divided Self: An Existential Study in Sanity and Madness (1960). He called his position ‘existential phenomenology’ (don’t ask!) and proposed that the delusional thinking of the schizophrenia patient was simply a different take on the world.
He argued that this could be challenging but it was essentially creative and, with enough imagination and moral courage, could be understood. However, these different worldviews threaten our security so we seek to deny them by imposing a diagnosis and ‘pathologizing’ them.
The book is filled with vivid descriptions of patients Laing had treated, accompanied with the most moving and imaginative interpretations of their dilemma. The impression given of psychosis by The Divided Self was of a tormented and rather heroic individual communicating vivid, authentic experiences, only to be met with a cowardly and mean-spirited rejection from society. R. D. Laing (1927–1989): the most influential and iconic of the anti-psychiatrists of the 1960s and 1970s not deny the suffering; his was essentially a romantic view of madness which (paradoxically) increased recruitment into psychiatry at the same time that it attacked it. Like Szasz, Laing never called himself an anti-psychiatrist (a term coined by his colleague David Cooper in 1967), and continued to practise, albeit in unorthodox ways.
Laing’s second ‘phase’ was his belief that families contributed to schizophrenia by denying the emerging identity of their child. Sanity, Madness and the Family: Families of Schizophrenics, with Aaron Esterson, cast schizophrenia as a response to repressive and rejecting parenting. The film inspired by it (Family Life, 1971) struck an international chord. Laing’s third phase was inspired by his extensive experimentation with LSD, so common at that time.

Anti-psychiatry in the 21st century
The contradictions inherent in psychiatry which generated the anti-psychiatry movement in the 1960s and 1970s have not gone away. Mind and brain, freedom and coercion, the right to be different (perhaps even the duty to be different), nature and nurture remain live issues. Many (though by no means all) ex-patient groups have become militantly anti-psychiatric, often referring to themselves as ‘survivors’ rather than patients, clients, or service users. In
Overall, however, there is now much less concerted opposition to psychiatry as a discipline. This may, in part, be due to a somewhat exaggerated faith in the rapid expansion of ‘biological’ explanations and an optimism that genetic and genomic advances will soon render the whole issue academic. However, while there is less conceptual opposition to psychiatry, there is no shortage of disquiet about various aspects of its practice.
