Psychosis in Women
Edit

Early detection and prompt treatment of psychosis is of the utmost importance. The great variability in clinical onset, illness course, and response to pharmacological and psychosocial treatment is in great part gender-related.

women psychosis schizophrenia gender differences personalized treatment

1. Introduction

In fact, there is sexual dimorphism in the development of brain areas [1][2] and this results in differences in the final volumes of gray and white matter [3][4][5]. This in turn results in the development of differential emotional skills between the two genders [6]. Sexual dimorphism affects the function of the dopaminergic system [7], which is known to be one of the central physio-pathogenetic mechanisms of schizophrenia and the psychoses in general [8][9][10][11]. Taken together, these studies point to differential characteristics of male and female brains right from the beginning of psychosis [12], thus to differential response to pharmacotherapy [13]. Therefore, reconsidering the evidence, the need for personalized, gender-related care emerges; this is stressed by recent studies [14][15][16].

There is a growing interest in current research focusing on several characteristics of psychotic illness separately analyzed in male and female populations. Subtle differences have been reported in many areas, with considerable implications for treatment [16]. Women may be disadvantaged as concerns access and quality of care for psychosis due to several factors, among which the fact that the emergence of psychosis is brought to clinical attention earlier for men than for women. Besides this, women have greater metabolic and endocrine-induced antipsychotic side effect risks. According to the estrogen hypothesis, estrogens raise the vulnerability threshold for the outbreak of the illness, so women would be protected against schizophrenia between puberty and menopause to some extent by their relatively high gonadal estrogen production during this time. This could explain the fact that women often have a later age of onset and could justify the belief that some therapeutic treatments associated with estrogens could be useful for improving symptoms and cognition, especially in women. According to the neurodevelopment hypothesis, it seems that women need more risk factors (such as family risk and life events) in order to develop schizophrenia than men, and this seems to be confirmed by the finding that usually men seem to present with a more deteriorated profile than women before the onset of the illness [17]. The existence of two distinct schizophrenias, masculine and feminine, has also been hypothesized. They would correspond to different forms of expression of specific psychotic symptoms and a different expression of psychotic illness due to the differential hemispheric organization, more symmetrically organized and less lateralized in the female compared to the male brain [18]. Some researchers have stressed the necessity to focus on the potential influence of the hypothalamic–pituitary–gonadal axis in the development of psychosis in women. In schizophrenia, an increased incidence has been shown in periods of low estradiol concentrations. Many women with schizophrenia, even in the untreated prodromal phase, experience estradiol deficiency and gonadal dysfunction, which might have put them at increased risk and might be due to stress-induced hyperprolactinemia [19]. It could be speculated that stress, which can induce hyperprolactinemia, has a stronger effect on women than on men in emerging psychosis [20][21]. Recently, central nervous system autoimmunity has been implicated in the etiology of psychosis, with specific gender differences [22]. It has been suggested that prolactin may underlie the excess of morbidity and early mortality in naïve patients with a first episode of psychosis through a specific pathway that intertwines inflammatory, immune and metabolic trajectories [23].

It can be argued that all possible models can contribute to explain gender differences in the predisposition to psychosis and in the expression and progression of illness. In people at high-risk of psychosis, differences between men and women in the expression of illness extend across a continuum, from the subclinical forms of illness to the debut of psychosis [12]. There are many special issues for women affected by psychosis that deserve particular attention, from sexuality (in terms of relationships, contraception, sexually transmitted diseases or sexual victimization) to the peripartum period (pregnancy, childbirth, postpartum period), from prescription of antipsychotic drugs to parenting (women with psychosis become parents much more frequently than men) and menopause [16].

To assess the need for personalized, gender-related interventions in the psychoses, especially schizophrenia, researchers conducted a literature search focusing on gender-related care for schizophrenia and related spectrum disorders. Given the importance of the presence of differential characteristics at the start of a clinical course [12], which points to the need to avoid delays in care, researchers focused on the first episode of psychosis (FEP).

2. Discussion

The fact that women often present with mood symptoms and tend to have better overall functioning at psychotic symptom onset compared with men may result in misdiagnosis and/or underestimation of their needs with a consequent delay in treatment and disadvantages in the subsequent course of illness [15].
Women are at a higher risk for metabolic and endocrine-induced side effects of antipsychotic drugs. This seems to be partly due to sex-specific pharmacokinetics (higher concentrations of free drug in target sites), enhancement of dopamine blockade by estrogen hormones, longer storage of antipsychotic drugs (due to the greater proportion of adipose tissue in women’s bodies), and higher risk of drug–drug interactions (because of women’s greater likelihood to being treated for comorbid illnesses) [16].
Besides the above, women are more likely to develop obesity, metabolic syndrome, cardiovascular diseases, and tardive dyskinesia after long-term treatment with antipsychotic drugs. This is probably due to the fact that women respond to acute stressors in a more pro-inflammatory manner compared to men, with increased immune response and decreased glucocorticoid sensitivity; in addition, gender difference of sex hormones profile and fluctuations, particularly during reproductive years, partly contribute to the increased burden of physical comorbidity observed in young female patients with a diagnosis of psychosis [24]. It has been noticed that chronic physical illnesses, although preventable and treatable, are the leading cause of premature mortality in patients with schizophrenia spectrum disorder [25].
Generally female patients tend to have better psychosis treatment outcomes and better control of physical comorbidities, with a consequent longer survival, because compared to men they tend to seek health care earlier and usually have more frequent clinical consultation rates. In such perspective, it has been also observed that young women with emerging psychosis have a higher correlation of self-rating with observer-rating regarding psychotic symptoms, and generally show better help-seeking behavior and are more partner-oriented when compared with men [26]. This may depend on greater insight of women compared to men and is confirmed by higher social functioning and less behavioral problems [27], but has the potential negative consequence of underestimating the real needs of female patients and jeopardizing engagement with psychiatric services. It has been noticed that, particularly for female patients with early psychosis, since subjective cognitive impairment seems to be significantly predicted by depression, treatments should not only focus on symptomatic remission and improved performance on cognitive tests, but also concentrate on improving mood and subjective cognitive function [28]. In a sample of adult-onset psychosis (defined as having an age of onset after 18 years of age, but in this particular sample, people whose psychosis emerged after the age of 25 years) the higher levels of correlation observed between female social functioning, negative symptoms and cognition, particularly executive function, suggest that these aspects are more interrelated that in men [29].
A very important issue is represented by differences in the long-term outcomes after a first episode of psychosis. As already reported, women show better outcomes, particularly during the first three years of treatment delivered at early intervention services, usually due to more favorable premorbid profiles and baseline characteristics. Moreover, the higher rates of mortality in patients with schizophrenia and comorbid substance use disorder (SUD) compared to those without SUD should be taken into account [30]. SUDs are dramatically oriented towards a male use, especially in adolescents and young adults presenting with psychotic symptoms [31]. This association between male gender and substance use can therefore represent the main reason explaining the worse outcome for males, at least at the beginning of the illness. However, not all adolescents who show some psychotic-like symptoms do convert into full-blown psychosis. After an average period of ten years, outcomes for women tend to approximate those of men, while there is a general increase in dosage of antipsychotic medication once patients at first episode psychosis are transferred to community-based services. As a result, it can be argued that targeting sex differences, improving personalized approaches and prolonging the observation period at early intervention services should be considered a priority in treating psychosis [32]. A better collaboration between early intervention service and community-based service staffs could also help this goal.
Very often women spend more time than men in caregiving for infants and elderly relatives and consequently may not give priority to their own physical and mental health, so there is a need to program specialty team-based services for first-episode psychosis in close cooperation with primary care and pediatric services, in order to facilitate a timely and adequate access to care [15].
The present review contributes to confirm that both men and women inevitably have peculiar service needs for first episode and subsequent course of psychosis. Understanding gender-based specificity at first presentation, development and long-term progress of psychosis might facilitate better treatment orientation or identify patients especially likely to respond to a particular treatment [25]. The suggestion that women’s experiences in emotions are different from those of men, particularly but not only in cultures where gender roles and labels are still persistent, is basic for improving the study of gender-related issues and improving care programs that especially look at women’s mental health [28]. For example, it could be useful to take into account that women have a unique risk for developing psychosis in the peripartum period and traumatic events such as intimate partner violence, which affects more women than men, and is linked to an increased risk of psychotic experiences [15][33].
Furthermore, the possibility exists that men and women express differential relationships between psychopathology and cognition, and this could have remarkable implications for a better understanding of the neurobiological basis of psychosis and for future individualized interventions [29]. This would help not only to improve prediction of psychosis but also to deepen existing knowledge about possible sex-related differences in pathogenetic pathways and, consequently, to identify at-risk states [34]. Alongside further investigations of gender differences in illness behavior, coping, help seeking, compliance, psychopharmacology, hormone therapies, psychotherapy, and rehabilitation, there is a need for more methodologically sound, longitudinal, multidomain and interdisciplinary research focusing both on the sex (biological) and gender (psychosocial) perspective [35].
The transition to psychosis has been shown to occur according to a staging model much like the staging of the development of other medical disorders such as cancer and hypertension [36][37][38]. The staging has been proposed to be characterized by gender-specific factors [39][40]. Such factors have to be taken into account in implementing interventions aiming at improvement psychosis outcomes,
Another issue that should be taken into account is age. Age at onset of psychosis differs between males and females, with the latter presenting usually later, possibly also as a function of the protective role of the hormonal status of women [41]. Hence, those with earlier onset in females are likely to represent the most severe cases among them [42]. This further suggest that generalization is not always feasible, thus personalized care is the way forward.

3. Conclusions

Overall, from this review it is possible to conclude that gold standard care for psychosis should not only carefully consider different symptoms and specific characteristics of the two sexes but also addresses all the physiological, psychological, and social role needs of men and women suffering from this psychiatric disorder. Tailored treatment plans delivered by healthcare services should consider gender differences in prevalence, onset, clinical characteristics, treatment-response, outcome, comorbidities, aiming to deliver sex-specific prevention strategies, personalized care and effective outcomes in patients with a diagnosis of psychosis, with a particular attention to early phases of disease in the context of the staging model of psychosis onset.
