Psychotic Disorders in Women

HISTORY OF PSYCHOSIS: A FEMALE PERSPECTIVE
Psychiatric history reflects the thoughts and views of philosophers, clerics, and clinicians, predominantly male. The dominant paradigm is male. In order to understand current concepts regarding women and psychosis, it is important to learn about the history of psychiatry from a female perspective. The search for historical contributions from early female thinkers yields little. Interestingly, the famous female patron saint of the mad, St. Dympna, gained her status by mishap. St. Dympna was a seventh-century martyr who fled from Ireland to Belgium to escape the incestuous desire of her father. He caught her and struck off her head in his fury at her rejection. This was observed by several “lunatics,” who were immediately shocked into sanity. She then earned the title of “protectress of the mad,” and favorable changes in psychosis were attributed to her intercession. This myth contains several messages about the associations between women and madness. Unlike many male saints, St. Dympna was a victim and not a powerful
person in her own right. The accidental but beneficial outcome for the mad patients conferred martyr status on St. Dympna but enshrined her role as passive. To this day, many inpatient units around the world are called St. Dympna’s Ward.

The twelfth century and other middle ages saw the devastating persecution of women, in particular women with mental illness, through the notorious witch hunts. For women, the consequence of psychotic symptoms was in many instances a painful death. A famous religious visionary in the twelfth century was Hildegard of Bingen. She wrote extensively about gender differences, sexuality, and medicine with a particular regard for women suffering from psychotic disorders. Hildegard claimed her revolutionary treatments for psychosis were transmitted to her in “dreams” and were in fact the ideas of the current pope. In this way she cleverly avoided persecution for witchery, which would have been her fate had she not adopted a passive role. Hildegard of Bingen’s theories about mental illness in women actually fit our current thinking in that she advocated a biopsychosocial approach to the etiology and treatment of psychosis.
During the midseventeenth century, rising unemployment and economic crises throughout Europe led to the building of institutions for the poor, the criminal, the alcoholic, and the mad. During this “classical age,” madness was seen as a type of moral corruption. Toward the end of the eighteenth century, particularly in France, industry was growing and workers were needed. This led to the release of psychiatric inmates who were capable of working, in particular large numbers of women deemed less severely mad than their male counterparts. Foucault claims that, at this time, when disease spread through French towns, the mad were blamed for the various epidemics and hence doctors became involved with the insane. Initially, doctors acted as moral guardians for the mad, rather than as physicians, but a medical interest in psychosis developed over time. The nineteenth century saw the proliferation of scientific theories about psychosis, coincident with the weakening power of the church and the rising importance of science. In the Victorian era, English psychiatrists theorized that female insanity was largely due to the woman overstepping the boundaries of femininity as determined by Victorian society. By the 1850s, the population of public asylums increased dramatically, with proportionally larger numbers of women than men. The Victorians associated female sexuality, deviancy, and madness. Women who were promiscuous, or who bore an illegitimate child, or those who were sexually assaulted and traumatized as a result, were seen as “mad” because they posed a threat to the view of women as passive and sexually innocent. On frequent occasions, such women were hidden away in asylums. The number of women assumed to be suffering from mental illness in the Victorian era was only partly reflected in the number restrained in asylums, since many were confined to attics or other hiding places. Literary works of the Victorian era, such as Florence Nightingale’s Cassandra, were to some extent semi-autobiographical accounts, and some portrayed the female perspective about the plight of the mad woman. The madness of Bertha, one of the main characters in “Jane Eyre,” was linked to her sexuality, and her worst episodes were related to her menstrual cycle. In the novel, Bertha was managed by confinement to a windowless attic and was treated as a brutish animal. This novel had a profound effect on Victorian readers, including psychiatrists, who subsequently advocated asylum treatment for women in preference to isolation at home.
Darwin’s theories of biologic sex differences gave scientific confirmation to the Victorian ideals of femininity. In The Descent of Man, Darwin described differences
in mental powers of the two sexes. He claimed that, through natural selection, man had become superior to woman in intellect, courage, and inventive genius. Henry Maudsley, a notable Victorian era psychiatrist and the editor of the journal Mental Science, was profoundly influenced by Darwin’s theories. Maudsley’s view was that higher education of women directly contributed to their mental illness.

During the latter part of the nineteenth century, the feminist movement gathered momentum, with women campaigning for access to universities, the professions, and the vote. Many of these women were labeled mentally disturbed, and the diagnosis of hysteria rose in prominence. A strong association was made between rebelliousness and nervous disorders, and there are documented cases of radical women being committed to asylums with symptoms of “overeducation and rebelliousness.” One such case was that of Edith Lancaster, described as an honors student at London University working for the Social Democratic Federation in 1895, who was committed to a private London asylum by her father after she began to live with a young railway clerk. The doctor involved explained that her opposition to conventional matrimony and her overeducation were the causes of her insanity. The diagnosis of hysteria, known as the “daughter’s disease” was also understood as a mode of expression for women deprived of social and intellectual outlets.
Freud attributed hysterical symptoms to sexual conflicts. Through Freud’s work, the female patient’s voice became audible. Following World War I, psychiatric attention turned again toward the psychotic disorders—grouped under the heading of “dementia praecox” by Kraepelin in 1896. Kraepelin believed that psychological dysfunction, “a loss of inner unity of intellect, emotion and volition,” was secondary to organic brain changes. Kraepelin’s theory was modified by Eugene Bleuler, who suggested the term “schizophrenia” in 1908. Bleuler believed the primary problem was an organic loosening of associations, which was the substrate for subsequent psychological mechanisms resulting in delusions and hallucinations. During the 1920s and 1930s, the concept of schizophrenia became much looser and acquired a strong social component that included adolescent turmoil, cultural maladjustment, and political deviation. In this era, the woman with schizophrenia became a central cultural figure, a symbol of linguistic, religious, and sexual breakdown. Yeats’s poem “Crazy Jane” in the 1930s and other literature such as “The Mad Woman of Chaillot” in 1945 depicted psychotic women as symbols of repression by society. Women were overrepresented in the number of asylum inpatients in the 1940s and received the majority of organic treatments (insulin and shock therapies). Since 1941, most of the 15,000 leucotomies and lobotomies performed have been on women.
By the 1960s, the feminist movement had grown and found favor with antipsychiatry groups (e.g., R. D. Laing). By the early 1970s, feminists became disenchanted with the antipsychiatry movement, and the early 80s saw the beginning of deinstitutionalization, a worldwide phenomenon of downsizing mental hospitals. The deinstitutionalization process has meant that many psychiatric patients in previous long-stay hospitals are now treated in general hospital units with an emphasis on community-based treatment. This has no doubt improved the quality of life of a significant proportion of patients with mental illness but has raised another issue for women in general—the burden of care. Sedgwick described women as being tied to “traditional servicing roles for their disabled kinfolk … the reinforcing of an archaic sexual division of labour”(1). The 1990s and
onward have seen the further growth of neuroscience technologies. This has, in turn, impacted on psychiatric research and, in particular, on schizophrenia research. Newer treatments have been developed, and there is greater understanding of brain impairment in psychosis. The consideration of differences between the sexes in schizophrenia has also received new attention. Sex differences in brain development, organization, and, eventually, degeneration are relevant to understanding sex differences in schizophrenia. Understanding sex differences in the experience of schizophrenia becomes increasingly important as the efficacy of newer treatments is being assessed.

EPIDEMIOLOGY OF FEMALE SCHIZOPHRENIA
It is almost universally accepted that schizophrenia first manifests at a later mean age in females than males. Most of the epidemiologic findings come from the Danish Case Register and the Central Institute of Mental Health, Mannheim, Germany (2,3,4). The mean age of onset of schizophrenia in women is now established as being between 5 and 10 years later than in men. Another well-documented sex difference is in the course and outcome of schizophrenia. Many studies report that women have a more benign course of illness than men (5). Overall, women show fewer negative symptoms, better social adaptation, and treatment response at relatively lower dosages of antipsychotic drug (6). However, social stressors such as homelessness, poverty, and victimization can create a very poor quality of life for women with psychotic illness (7).
THEORIES OF ETIOLOGY: A SEX-BASED APPROACH
NEURODEVELOPMENTAL THEORIES
Normal sexual dimorphisms in brain structures have been demonstrated in many animals, including humans (8). The male preoptic nucleus is larger than the female’s, with more cells and larger cells. There is a higher density of neurons in the orbital area of females than in males and the planum temporale shows more right/left shape asymmetry in males.
The question of whether structural cerebral changes are pathognomonic of schizophrenia and inevitably progressive remains controversial. Many studies suggest that the extent of these structural changes differs widely depending on the imaging methods employed, individual characteristics, and the size of the sample studied. A variety of cerebral structures have been investigated, including the hippocampal formation, the cerebellum, and the basal ganglia. A majority of studies have focused on the frontal and temporal lobes. Some find no significant prefrontal cortex gray matter, white matter, or total volume changes in persons with schizophrenia compared to controls, but Bachmann et al. found a decrease of frontal lobe volume in people with first-episode schizophrenia (9). In other work, such as that by Pantelis et al., significant changes relative to controls have been found in the hippocampal volume of prepsychotic persons (10). An important variable that is often overlooked in structural cerebral imaging studies is the need to compare male patients with male controls and female patients with female controls.
The volume of the caudate nucleus increases over time in first-episode patients who receive treatment with conventional antipsychotic medication. This effect
is dose dependent and associated with younger age at the beginning of the illness (11). Moreover, a direct effect of conventional antipsychotics on the D2 dopamine receptor system, with receptor up-regulation has also been described in functional imaging studies (12). Treatment with atypical antipsychotics does not cause volume increases in the caudate (13).

Treatment with atypical antipsychotics does not cause volume increases in the caudate (13).
The main conclusion is that there is no convincing evidence that schizophrenia in either sex is accompanied by a progressive loss of global cerebral tissue. Regional changes of frontal and temporal lobe volumes may occur in subgroups of patients and may be related to certain stages of the disease (14).
GENETICS OF SCHIZOPHRENIA AND RELATED DISORDERS
The clinical phenotype of schizophrenia is a highly complex entity with multiple neurochemical, physiologic, and psychological features. Different brain pathways may be under the influence of different susceptibility genes or environmental factors. The investigation of the expression of thousands of genes in mRNA tissue has recently become feasible (15). Illness can be caused by specific sequence anomalies in the DNA (genetics) or by heritable changes in gene expression occurring without necessarily altering DNA sequence (epigenetics) (16). The main known epigenetic mechanisms are inactivation of genes via methylation or acetylation. It has been suggested that schizophrenia has an epigenetic basis (17). The systematic search for vulnerability genes offers strategies for disease-gene identification in schizophrenia.
HORMONAL ASPECTS OF THE ETIOLOGY OF SCHIZOPHRENIA
By and large, it is agreed that schizophrenia is a postpubertal disorder in both males and females. Thus, it is important to understand the effect of the HPG axis hormones, particularly estrogen and testosterone, on neurotransmitter systems involved in schizophrenia. In neonatal and adult rats, Behrens et al. studied the effects of estradiol and testosterone on cataplexy induced by the dopamine antagonist, haloperidol (18). Ferretti et al. found that estrogen administration had little effect on dopamine D1 receptors but that D2 receptor density fell in response to low-dose estradiol (19). Fink and colleagues have also shown that estrogen induces a significant increase in 5-HT2A receptors and the serotonin transporter (SERT) in regions in the rat forebrain that mediate mental state, mood, cognition, memory, emotion, and neuroendocrine control (20). Estrogen may protect against psychotic symptoms by way of its actions on the 5-HT2A receptor, SERT, and the D2 receptor.
SCHIZOPHRENIA IN WOMEN: A LIFE-CYLE APPROACH
EARLY PSYCHOSIS IN WOMEN: POSTPUBERTY TO LATE ADOLESCENCE
During class, in the quiet of the work period, I could hear the street noises … each detached, immovable, separated from its source, without meaning. Around me, the other children … were robots or puppets, moved by an invisible mechanism. On the platform, the teacher, too, talking, gesticulating, rising to write on the blackboard, was a grotesque jack-in-the-box…. An awful terror bound me; I wanted to scream. (21)
This is an excerpt from an autobiography of a girl with schizophrenia during what we would now call the early psychosis phase.
The peak period of onset for men with schizophrenia is 18 to 25 years of age and, for women, 25 to midthirties (3). The size of the age difference depends on the strictness of the criteria for defining the case (2). In early adolescence, the male:female onset ratio is generally 2:1 (22). Approximately 3% to 10% of women have an age of onset greater than 45 years (rare for males) (22). Using an admixture analysis technique, Castle et al. re-analyzed the Camberwell data set; their main findings were that the early-onset peaks showed a marked excess of males, the middle-onset peak was female preponderant, and the very-late-onset peak was exclusively female (22). Although the mean is later age of onset of psychosis in women, this does not exclude first-time presentation of psychosis in adolescent girls. Special care must be taken not to overlook the illness unexpectedly presenting for the first time in very young women.
