Despite the growing amount of data, much information is needed on patients' mental capacity to consent to psychiatric treatment for acute mental disorders. The present study was undertaken to compare differences in capacity to consent to psychiatric treatment in patients treated voluntarily and involuntarily and to investigate the role of psychiatric symptoms, competency, and cognitive functioning in determining voluntariness of hospital admission. Involuntary patients were interviewed with the MacArthur Competence Assessment Tool for Treatment (MacCAT-T), the 24-item Brief Psychiatric Rating Scale (BPRS), the Mini Mental State Examination (MMSE) and the Raven's Colored Progressive Matrices, and their data were compared with those for age- and sex-matched voluntary patients. Involuntary patients performed worse in all MacCAT-T subscales. Capacity to consent to treatment varied widely within each group. Overall, involuntary patients have worse consent-related mental capacity than those treated voluntarily, despite capacity to consent to treatment showing a significant variability in both groups.
Treatment DMC can be routinely assessed in non-consensual psychiatric settings by the MacCAT-T, as is the case of other clinical variables. Such approach can lead to the identification of patients with high treatment DMC, thus drawing attention to possible dichotomy between legal and clinical status.
Despite the acknowledged influence of cognition on patients' capacity to consent to treatment, the specific neuropsychological domains involved remain elusive, as does the role of executive functions. We investigated possible associations between executive functions and decisional capacity in a sample of acute psychiatric inpatients. Patients were recruited and evaluated through the MacArthur Competence Assessment Tool for Treatment (MacCAT-T), the 24-item Brief Psychiatric Rating Scale (BPRS), the Mini-Mental State Examination (MMSE), and the Wisconsin Card Sorting Test (WCST). Patients with poor executive functioning performed worse in MacCAT understanding, appreciation, and expression of a choice, compared with good performers. These findings point to the importance of cognition in decisional capacity processes. In addition, the strong association found between learning abilities and informed consent decision-making provide empirical evidence indicating possible cognitive enhancement strategies that may improve psychiatric patients' competency.
Why do people find conspiracy theories attractive, convincing, or useful? In this article, I analyze conspirituality—that is, the relationships between New Age spirituality and conspiracy theories—in Italy during the COVID-19 lockdown. After distinguishing between conspiracy-believing and belief in conspiracies, I claim that conspiracy-believing could be understood as an aesthetic (sensory and artistic) practice. In doing so, I offer a novel interpretation on conspiracism that complements current scholarship while departing from the latter’s focus on the cognitive and emotional weaknesses of those who adopt conspiracy theories. By engaging with the thought of Jacques Rancière, in conversation with studies on contemporary Paganism and Western esotericism, I consider the adoption of conspiracy theories as an expression of dissensus by a community of sense that does not look only for visibility but, rather, wants to be fully acknowledged, recognized, and legitimized in their “participatory”—or “magical”—way of inhabiting the world.
The present study was designed to compare gender differences in psychiatric diagnosis with the dimension of psychopathy in women and men who had attempted or committed homicide. The study samples consisted of 39 homicidal females and 48 homicidal males who were confined in one of Italy’s REMS or prison facilities in two southern provinces of Italy (Puglia and Basilicata). Assessment instruments included the SCID‐5, the PID‐5 IRF, and the PCL‐R. Each gender group was stratified according to the level of criminal responsibility for the homicidal offense (full, partial, absent), and after assessments, according to the degree of the psychopathic dimension. There were clear gender differences in homicidal individuals. Female offenders were less likely to have had a record of criminal charges/convictions or imprisonment, and their homicides were more often intrafamilial, victimizing especially of their children, whereas males targeted intimate partners and extrafamilial victims. In the entire group, there was an inverse relationship between the level of psychopathy and the personality disorder on one side, and the psychotic disturbance on the other. Factor 2 (lifestyle/antisocial dimension) of the PCL‐R was higher among the homicidal males, whereas females tended to score higher on Factor 1 (the interpersonal/affective dimension). Finally, if the psychopathic dimension is a qualifier for antisocial personality disorder, as indicated in DSM‐5, this appears to be less true for females who tend to have other personality disorders.
Objectives: To perform a meta-analysis of clinical studies on the differences in treatment or research decision-making capacity among patients with Mild Cognitive Impairment (MCI), Alzheimer’s disease (AD), and healthy comparisons (HCs). Design: A systematic search was conducted on Medline/Pubmed, CINAHL, PsycINFO, Web of Science, and Scopus. Standardized mean differences and random-effects model were used in all cases. Setting: The United States, France, Japan, and China. Participants: Four hundred and ten patients with MCI, 149 with AD, and 368 HCs were included. Measurements: The studies we included in the analysis assessed decisional capacity to consent by the MacArthur Competence Assessment Tool for Treatment (MAcCAT-T), MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR), Capacity to Consent to Treatment Instrument (CCTI), and University of California Brief Assessment of Capacity to Consent (UBACC). Results: We identified 109 potentially eligible studies from 1672 records, and 7 papers were included in the meta-analysis. The meta-analysis showed that there was significant impairment in a decision-making capacity in MCI patients compared to the HCs group in terms of Understanding (SMD = −1.04, 95% CI: −1.31 to −0.77, P < 0.001; I2 = 52%, P = 0.07), Appreciation (SMD = −0.51, 95% CI: −0.66 to −0.36, P < 0.001; I2 = 0%, P = 0.97), and Reasoning (SMD = −0.62, 95% CI: −0.77, −0.47, P < 0.001; I2=0%, P =0.46). MCI patients scored significantly higher in Understanding (SMD = 1.50, 95% CI: 0.91, 2.09, P = 0.01, I2 = 78%, P = 0.00001) compared to patients affected by AD. Conclusions: Patients affected by MCI are at higher risk of impaired capacity to consent to treatment and research compared to HCs, despite being at lower risk compared to patients affected by AD. Clinicians and researchers need to carefully evaluate decisional capacity in MCI patients providing informed consent.
<b><i>Introduction:</i></b> In recent years, research on posttraumatic stress disorder (PTSD) focused on the description of different biological correlates of illness. Morphological changes of different brain regions were involved in PTSD neurophysiopathology, being related to trauma or considered a resilience biomarker. In this meta-analysis, we aimed to investigate the grey matter changes reported in magnetic resonance imaging (MRI) studies on patients who have developed PTSD compared to exposed subjects who did not show a clinical PTSD onset. <b><i>Methods:</i></b> We meta-analysed eight peer-reviewed MRI studies conducted on trauma-exposed patients and reported results corrected for false positives. We then conducted global and intergroup comparisons from neuroimaging data of two cohorts of included subjects. The included studies were conducted on 250 subjects, including 122 patients with PTSD and 128 non-PTSD subjects exposed to trauma. <b><i>Results:</i></b> Applying a family-wise error correction, PTSD subjects compared to trauma-exposed non-PTSD individuals showed a significant volume reduction of a large left-sided grey matter cluster extended from the parahippocampal gyrus to the uncus, including the amygdala. <b><i>Conclusions:</i></b> These volumetric reductions are a major structural correlate of PTSD and can be related to the expression of symptoms. Future studies might consider these and other neural PTSD correlates, which may lead to the development of clinical applications for affected patients.
