BACKGROUND AND OBJECTIVES
Anecdotal and research evidence suggests that individuals with dissociative symptoms exhibit hyperassociativity, which might explain several key features of their condition. The aim of our study was to investigate the link between dissociative tendencies and hyperassociativity among college students.
METHODS
The study (n = 118) entailed various measures of hyperassociativity, measures of dissociative tendencies, depressive experiences, unusual sleep experiences, cognitive failures, and alexithymia.
RESULTS
We found a positive association between dissociative experiences (i.e., depersonalization) and hyperassociativity specific for associative fluency and associative flexibility tasks (including neutral and valenced material), but not for a remote association task. We also found tentative evidence for cognitive failures and alexithymia explaining the link between hyperassociativity and daytime dissociation and nighttime unusual sleep experiences.
LIMITATIONS
Limitations include the use of hyperassociation tasks limited to verbal associations vs. imagistic associations, the lack of a measure of trauma history, and a sample limited to college students.
CONCLUSION
Our study reports a link between depersonalization and hyperassociativity on tasks that allow for free associations across different semantic domains, potentially explained by alexithymia and cognitive failures. This finding may, with replication, open the pathway to applied intervention studies.

Review
The clinical heterogeneity of dissociation constitutes a challenge to the culture-sensitive clinician. Variability in experiencing dissociation, the interplay between acute and chronic conditions, and the predominance of a nosologically interface-type of clinical surface conceal core dissociative symptoms. While the latter (amnesia, depersonalization, derealization, identity confusion, and identity alteration) usually remain underreported, the clinical surface may be dominated by acute (functional neurological symptoms, brief psychosis, an experience of possession, or acute dissociative reaction to a stressful event) or chronic (mood and personality disorders) secondary syndromes. However, these syndromes also constitute gateways in pursuing the clues of core dissociation. Given that culture influences communication between clinician and patient, accurate expression of mental content requires the idiomatic armamentarium describing the experience. The latter is problematic in dealing with phenomena of core dissociation while the secondary representations have a relatively universal character for both clinicians and patients. Nevertheless, this approach requires a transdiagnostic understanding in conceiving this clinical interface. This interface reflects, in fact, complications of dissociative disorders which require to be addressed in the first line. This is either due to the medical and psychiatric urgency (e.g., functional neurological symptoms, brief psychosis) or due to resistance to treatment (e.g., antidepressant pharmacotherapy) which seem to be indicated for the particular condition. This transdiagnostic schema is based on a combined utilization of etic and emic principles in the cultural understanding of psychiatric disorders. Namely, universal medical-psychiatric categories are conceived as tools of communication and mutual understanding rather than being mere appearances or primary disturbances.

Review
BACKGROUND
Dissociative disorders encompass loss of integration in essential functions such as memory, consciousness, perception, motor control, and identity. Nevertheless, neuroimaging studies, albeit scarce, have suggested the existence of particular brain activation patterns in patients belonging to this diagnostic category. The aim of this review is to identify the main functional neuroimaging correlates of dissociative disorders.
METHODS
we searched the PubMed database to identify functional neuroimaging studies conducted on subjects with a diagnosis of a dissociative disorder, following the PRISMA guidelines. In the end, we included 13 studies in this systematic review, conducted on 51 patients with dissociative identity disorder (DID), 28 subjects affected by depersonalization disorder, 24 with dissociative amnesia, and 6 with other or not specified dissociative disorders.
RESULTS
Prefrontal cortex dysfunction seems prominent. In addition, changes in the functional neural network of the caudate are related to alterations of identity state and maintenance of an altered mental status in DID. Another role in DID seems to be played by a dysfunction of the anterior cingulate gyrus. Other regions, including parietal, temporal, and insular cortices, and subcortical areas were reported to be dysfunctional in dissociative disorders.
CONCLUSIONS
Prefrontal dysfunction is frequently reported in dissociative disorders. Functional changes in other cortical and subcortical areas can be correlated with these diagnoses. Further studies are needed to clarify the neurofunctional correlations of each dissociative disorder in affected patients, in order to identify better tailored treatments.

Review
It has been claimed that the progress of psychiatry has lagged behind that of other medical disciplines over the last few decades. This may suggest the need for innovative thinking and research in psychiatry, which should consider neglected areas as topics of interest in light of the potential progress which might be made in this regard. This review is concerned with one such field of psychiatry: dissociation and dissociative disorders. Dissociation is the ultimate form of human response to chronic developmental stress, because patients with dissociative disorders report the highest frequency of childhood abuse and/or neglect among all psychiatric disorders. The cardinal feature of dissociation is a disruption in one or more mental functions. Dissociative amnesia, depersonalization, derealization, identity confusion, and identity alterations are core phenomena of dissociative psychopathology which constitute a single dimension characterized by a spectrum of severity. While dissociative identity disorder (DID) is the most pervasive condition of all dissociative disorders, partial representations of this spectrum may be diagnosed as dissociative amnesia (with or without fugue), depersonalization disorder, and other specified dissociative disorders such as subthreshold DID, dissociative trance disorder, acute dissociative disorders, and identity disturbances due to exposure to oppression. In addition to constituting disorders in their own right, dissociation may accompany almost every psychiatric disorder and operate as a confounding factor in general psychiatry, including neurobiological and psycho-pharmacological research. While an anti- dissociative drug does not yet exist, appropriate psychotherapy leads to considerable improvement for many patients with dissociative disorders.

Heliyon Oct 2022Twisties symptoms have attracted the world's attention in the sports field since the 2020 Tokyo Olympics.
RESEARCH BACKGROUND
Twisties symptoms have attracted the world's attention in the sports field since the 2020 Tokyo Olympics.
AIM
However, studies on the symptoms and causes, inducing mechanisms, and relationships between DP/DR (Depersonalization/Derealization Disorder) and anxiety and depression for athletes have been sparse for both the general population and athletes. The literature on the twisties issue of athletes is quite scarce in the past.
RESEARCH METHOD
Adopting the criteria appealing to PRISMA Items to review the subject twisties in a broader mode and combing with the IPO (Input-Process-Output) model for triangulation testing purpose, this study categorized the literature to explore input variables causing athletes' twisties and identified process variables in psychological mechanisms bridging suppression and finally discussed the existing possible ways in helping athletes to solve problems caused by twisties.
RESULTS
The authors formed 6 propositions in summarizing twisties' influential factors and mechanisms and tried to propose solutions to reduce the stress and the relevant twisties symptom of athletes. (1) Promotion of Athletes' Mental Toughness to Resist Stressors. (2) Interventions that correct for cognitive misinterpretations and appropriate relaxation and mindfulness practice in correcting a range of attention might reduce DP/DR. (3) Monitoring the athlete's HRV test results to ensure the Athlete's ability to resist pressure. (4) Avoid organizational stressors. (5) Written Emotional Disclosure method. (6) Improve various support systems for athletes: dual career paths. (7) Athletes' Stressful Awareness about the impact of gender, seniority, and environment.
CONCLUSION
Through the theoretical dialogue on the symptom of twisties, this study helps promote the development of the research of "twisties" and depersonalization-derealization symptoms (DDS); both have been under-researched.

Review
In his paper "Whatever next? Predictive brains, situated agents, and the future of cognitive science," Andy Clark seminally proposed that the brain's job is to predict whatever information is coming "next" on the basis of prior inputs and experiences. Perception fundamentally subserves survival and self-preservation in biological agents, such as humans. Survival however crucially depends on rapid and accurate information processing of what is happening in the here and now. Hence, the term "next" in Clark's seminal formulation must include not only the temporal dimension (i.e., what is perceived ) but also the spatial dimension (i.e., what is perceived or next-to-my-body). In this paper, we propose to focus on perceptual experiences that happen "next," i.e., close-to-my-body. This is because perceptual processing of proximal sensory inputs has a key impact on the organism's survival. Specifically, we focus on tactile experiences mediated by the skin and what we will call the "extended skin" or "second skin," that is, immediate objects/materials that envelop closely to our skin, namely, clothes. We propose that the skin and tactile experiences are not a mere border separating the self and world. Rather, they simultaneously and inherently distinguish connect the bodily self to its environment. Hence, these proximal and pervasive tactile experiences can be viewed as a "transparent bridge" intrinsically relating and facilitating exchanges between the self and the physical and social world. We conclude with potential implications of this observation for the case of Depersonalization Disorder, a condition that makes people feel estranged and detached from their self, body, and the world.

BACKGROUND
Depersonalization and derealization (DPDR) syndrome results from complex interwoven sensory motor experiences seen across psychiatric disorders. There is sparse literature from India on DPDR symptoms, their clinical and research utility. This study focuses frequency of coding the diagnosis of DPDR (ICD-10) and critical discussion about its clinical and research utility.
METHODS
A retrospective review of case files coded under ICD code F48.1 was carried out for 10 years and details were systematically analyzed for age, gender, duration, phenomenology, comorbid diagnosis, and pharmacological treatment.
RESULTS
Fourteen patients received the diagnosis of DPDR. Mean duration of DPDR syndrome was 6 years (standard deviation [SD] = 2.2) while mean age of presentation to hospital was 24 years (SD = 2.5). Tactile imagery (50%), self-environmental integration (42%), and dream-reality integration (28%) were the major themes. Selective serotonin reuptake inhibitors were used as primary medication for 65% of patients.
CONCLUSION
Isolated DPDR syndrome has been diagnosed very rarely in recent past. Reasons may include ignoring the comorbid DPDR coding, inability to articulate DPDR symptoms, inadequate documentation and misinterpretation of symptoms or actually less prevalence of DPDR syndrome in India. Considering scanty literature on DPDR as a primary diagnosis, more studies are required to identify the actual prevalence and coding of DPDR in future.

Philosophers maintain that touch confers a sense of reality or grounding to perceptual experience. In touching oneself, one is simultaneously both subject and object of touch, a template for experiencing oneself as subject and object of intentions, feelings, and motivations, or intersubjectivity. Here, I explore a form of self-touch carefully documented by Winnicott in observing how the infant engages the transitional object. I compare the processes of self-loss in transitional states, including absorption in art, empathic immersion, drug-induced ego dissolution, and depersonalization. I use examples drawn from Rodin, Dante, and the Beatles; research correlating neurophysiological findings with aspects of self-representation; predictive processing-based models; Hohwy's concepts of minimal and narrative self; Clark's notion of the extended mind; and phenomenological perspectives on touch, to postulate a role for self-touch in the pre-reflective sense of mine-ness, or grounding, in transitional states.

Trauma-related pathological dissociation is characterized by disruptions in one's sense of self, perceptual, and affective experience. Dissociation and its trauma-related antecedents disproportionately impact women. However, despite the gender-related prevalence and high individual and societal costs, dissociation remains widely underappreciated in clinical practice. Moreover, dissociation lacks a synthesized neurobiological model across its subtypes. Leveraging the Triple Network Model of psychopathology, we sought to parse heterogeneity in dissociative experience by examining functional connectivity of three core neurocognitive networks as related to: (1) the dimensional dissociation subtypes of depersonalization/derealization and partially-dissociated intrusions; and, (2) the diagnostic category of dissociative identity disorder (DID). Participants were 91 women with and without: a history of childhood trauma, current posttraumatic stress disorder (PTSD), and varied levels of dissociation. Participants provided clinical data about dissociation, PTSD symptoms, childhood maltreatment history, and completed a resting-state functional magnetic resonance imaging scan. We used a novel statistical approach to assess both overlapping and unique contributions of dissociation subtypes. Covarying for age, childhood maltreatment and PTSD severity, we found dissociation was linked to hyperconnectivity within central executive (CEN), default (DN), and salience networks (SN), and decreased connectivity of CEN and SN with other areas. Moreover, we isolated unique connectivity markers associated with depersonalization/derealization in CEN and DN, to partially-dissociated intrusions in CEN, and to DID in CEN. This suggests dissociation subtypes have robust functional connectivity signatures that may serve as targets for PTSD/DID treatment engagement. Our findings underscore dissociation assessment as crucial in clinical care, in particular, to reduce gender-related health disparities.

OBJECTIVE
To analyze the association of excessive work and compulsive work with the dimensions of the burnout syndrome in masters and doctoral professors of Languages, Literature, and Linguistics in Brazil.
METHODS
Cross-sectional study carried out with 585 permanent professors of stricto sensu graduate studies in Languages, Literature, and Linguistics in Brazil. Data collection took place between February and August 2019, by an online questionnaire. The outcomes of this study were the compulsive work and excessive work dimensions of the Dutch Work Addiction Scale, the Maslach Burnout Inventory TM dimensions and their associated factors, identified by multiple logistic regression models.
RESULTS
Professors with a high level of excessive work (29.40%) had 2.75 times the chance of high emotional exhaustion and 2.08 times the chance of high depersonalization. Regarding professors with a high level of compulsive work (8.03%), they had 4.88 times the chance of high emotional exhaustion and 2.97 times the chance of high depersonalization. No association of excessive work and compulsive work with low professional fulfillment was identified.
CONCLUSION
The results showed a statistically significant association of excessive work and compulsive work with high emotional exhaustion and high depersonalization, allowing managers and professors to reflect the criteria that guide their work processes, to adopt management models, institutional regulatory policies, and strategies to improve the working conditions and health of professors.
