Special Issue Information

Dear Colleagues,

For several decades, the dopamine hypothesis of schizophrenia has appeared to explain the neurobiology of the disorder, the biological underpinnings of treatment response, and the primary mechanism of action in antipsychotic responses. However, a significant volume of research suggests that other biological and neurotransmitter systems are implicated. Patients with schizophrenia exhibit marked positive and negative symptoms, as well as present cognitive symptoms and affective domains. Although antipsychotics are considered the gold standard, preclinical and clinical studies report that almost one-third of patients with schizophrenia fail to respond to standard antipsychotic treatment.

The present Special Issue aims to summarize new evidence pertaining to the role of biological systems interacting with dopamine and other neurotransmitters, and their implication in the occurrence of psychotic symptoms and treatment responses. The role of stress hormones and other hormonal compounds in the clinical presentation (phenotype) and response to treatment will also be explored. Articles presenting evidence regarding the effectiveness of pharmacological and non-pharmacological interventions in treating schizophrenia and related disorders are also welcome, with a special emphasis on treatments targeting emotions and cognitive symptoms. The impact of physical health on psychotic symptoms and vice versa is also a topic of interest in psychotic populations.

Gender differences exist in mental and physical health in schizophrenia, and healthcare education is part of the associated clinical approach. The main goal of the present paper is to describe a women’s clinic for schizophrenia and carry out a narrative review about innovative healthcare and learning strategies in the context of women who suffer from schizophrenia, and to discuss innovative strategies for both healthcare and learning projects to be applied in this context. Observing the development of our unit, four clear innovation phases can be distinguished: the generation of new ideas (clinical and social needs), strategic planning (five observatories), the execution of these strategies (observatories/teams/interventions) and feedback, iteration and scaling. We found that the observatory for morbi-mortality adopted a retroactive proactive approach, and the observatory for hyperprolactinemia was proactive and deliberate. We describe the innovation aspects, both clinical and educational, as incremental. There was one exception, the introduction of a social exclusion and discrimination observatory, that from our perspective, was not gradual, but transformative. Future learning projects should include the role of social sciences and humanities and new technologies. Our pilot project gave us the opportunity to apply new learning methods to a relatively neglected field of care. Full article

Despite the fact that most persons with schizophrenia find steady employment difficult to sustain, many women with this diagnosis embrace and fulfill the most difficult task of all—motherhood. The aim of this paper is to specify the challenges of motherhood in this population and review the treatment strategies needed to keep mothers and children safe, protecting health and fostering growth. The review addresses concerns that had been brought to the author’s earlier attention during her clinical involvement with an outpatient clinic for women with psychosis. It is, thus, a non-systematic, narrative review of topic areas subjectively assessed as essential to “good enough” mothering in the context of schizophrenia. Questions explored are the stigma against motherhood in this population, mothers’ painful choices, issues of contraception, abortion, child custody, foster care and kin placement of children, the effects of antipsychotics, specific perinatal delusional syndromes, and, finally, the availability of parental support. This review is intended for clinicians. Recommendations are that care providers work collaboratively with mothers, take note of their strengths as well as their failings, offer a wide array of family services, monitor households closely for safety and for treatment adherence, appreciating the many challenges women with schizophrenia face daily.

Background/Objectives: Positive symptoms, negative symptoms, and emotional disturbances are core features of schizophrenia. Although horticultural therapy (HT) has shown promise as an adjunctive treatment, evidence supporting its effectiveness remains limited. This systematic review and meta-analysis aimed to assess the impact of HT on total symptoms, positive symptoms, negative symptoms, and emotional disturbances in individuals with schizophrenia. Methods: We conducted a search for randomized controlled trials (RCTs) published up to March 2024 across multiple databases, including PubMed, Embase, Cochrane Library, CINAHL, CEPS, CNKI, Wanfang, and Yiigle. A random-effects model was employed to calculate the standardized mean difference (SMD). Results: A total of 35 studies enrolling 2899 participants were included. Our results indicated that, in the short term (≦3 months), HT has moderate to large effect sizes on total symptoms (SMD = 0.690, 95% CI 0.463 to 0.916), positive symptoms (SMD = 0.695, 95% CI 0.038 to 1.351), negative symptoms (SMD = 0.681, 95% CI 0.395 to 0.967), depression (SMD = 0.646, 95% CI 0.334 to 0.959), and anxiety (SMD = 0.627, 95% CI 0.364 to 0.890), with more pronounced benefits for anxiety symptoms in patients with a shorter duration of illness. In the long term (>3 months), HT shows large effect sizes for total symptoms (SMD = 1.393, 95% CI 0.858 to 1.928), negative symptoms (SMD = 1.389, 95% CI 0.935 to 1.842), anxiety (SMD = 1.541, 95% CI 1.042 to 2.040), and moderate to large effect sizes for positive symptoms (SMD = 0.667, 95% CI 0.077 to 1.258) and depression (SMD = 0.707, 95% CI 0.198 to 1.217). Additionally, longer weekly treatment durations are associated with better outcomes for total symptoms and negative symptoms. Schizophrenia patients with more severe initial symptoms may be potential responders to HT. Conclusions: These findings support the efficacy of HT in improving symptoms and emotional well-being in schizophrenia patients. Further trials with more rigorous designs are warranted to confirm these benefits. Full article

Schizophrenia is characterized by psychiatric symptoms and emotional issues. While pharmacological treatments have limitations, non-pharmacological interventions are essential. Art therapy has the potential to enhance emotional expression, communication, and health; however, the effectiveness of visual art therapy remains uncertain. This systematic review and meta-analysis synthesizes the findings of randomized controlled trials (RCTs) of visual art therapy on positive symptoms, negative symptoms, and emotions in patients with schizophrenia. This study reviews RCTs published prior to February, 2024. The PubMed, Embase, Cochrane Library, CEPS, CNKI, Wanfang, and Yiigle databases were searched, and three independent researchers screened the studies. In this meta-analysis, standardized mean difference (SMD) was employed as a measure to calculate effect sizes for continuous variables using a random effects model, while the meta-regression and subgroup analyses were performed with patient and intervention characteristics. A total of 31 studies revealed visual art therapy had a significant small-to-moderate effect on positive symptoms (SMD = 0.407, 95% CI 0.233 to 0.581), a moderate effect on negative symptoms (SMD = 0.697, 95% CI 0.514 to 0.880), a moderate effect on depression (SMD = 0.610, 95% CI 0.398 to 0.821), and a large effect on anxiety (SMD = 0.909, 95% CI 0.386 to 1.433). The subgroup analysis revealed painting and handcrafts had significant effects on positive symptoms, negative symptoms, and emotions. Combined Chinese calligraphy and painting had significant effects on positive symptoms, depression, and anxiety. Better improvement was noted among the Asian population, and a longer weekly treatment duration was associated with better improvement in positive symptoms. Female participants tended to have more improvements in negative symptoms and anxiety through visual art therapy. The results indicate that visual art therapy has positive effects on the psychiatric symptoms and emotions of individuals with schizophrenia. We recommend future research further investigate art therapy modalities and durations. Full article
