Anorexia nervosa as a disorder of the subcortical-cortical interoceptive-self.

PURPOSE: Anorexia nervosa (AN) is characterized by a diminished capacity in perceiving the physiological correlates of interoceptive sensations, namely bodily self-consciousness. Given the neural division of self-processing into interoceptive-, exteroceptive- and mental-self, we hypothesize neural deficits in the interoceptive-processing regions in AN. METHODS: To prove this, we reviewed resting state (rs), task and rest-task studies in AN literature. RESULTS: Neuronal data demonstrate the following in AN: (i) decreased rs-functional connectivity (rsFC) of subcortical-cortical midline structures (SCMS); (ii) reduced rsFC between medial (default-mode network/DMN and salience network/SN) and lateral (executive-control network/ECN) cortical regions; (iii) decreased rsFC in mainly the regions of the interoceptive-self; (iv) altered activity with overall increased activity in response to sensory/body image stimuli, especially in the regions of the interoceptive-self; (v) lack of a clear task-related distinction between own's and others' body image. CONCLUSION: These data may indicate that rs-hypoconnectivity between SCMS, as neural correlate of a reduced intero-exteroceptive integration resulting in self-objectification, might be linked to overall increased activity in interoceptive regions during sensory/body image stimuli in AN, engendering an "anxious bodily self." LEVEL OF EVIDENCE: I: Systematic review.

The impact of COVID-19 epidemic on eating disorders: A longitudinal observation of pre versus post psychopathological features in a sample of patients with eating disorders and a group of healthy controls.

OBJECTIVE: the aim of this longitudinal study was to evaluate the impact of COVID-19 epidemic on Eating Disorders (EDs) patients, considering the role of pre-existing vulnerabilities. METHOD: 74 patients with Anorexia Nervosa (AN) or Bulimia Nervosa (BN) and 97 healthy controls (HCs) were evaluated before lockdown (T1) and during lockdown (T2). Patients were also evaluated at the beginning of treatment (T0). Questionnaires were collected to assess psychopathology, childhood trauma, attachment style, and COVID-19-related post-traumatic symptoms. RESULTS: A different trend between patients and HCs was observed only for pathological eating behaviors. Patients experienced increased compensatory exercise during lockdown; BN patients also exacerbated binge eating. Lockdown interfered with treatment outcomes: the descending trend of ED-specific psychopathology was interrupted during the epidemic in BN patients. Previously remitted patients showed re-exacerbation of binge eating after lockdown. Household arguments and fear for the safety of loved ones predicted increased symptoms during the lockdown. BN patients reported more severe COVID-19-related post-traumatic symptomatology than AN and HCs, and these symptoms were predicted by childhood trauma and insecure attachment. DISCUSSION: COVID-19 epidemic significantly impacted on EDs, both in terms of post-traumatic symptomatology and interference with the recovery process. Individuals with early trauma or insecure attachment were particularly vulnerable.

Psychosexual Correlates of Unwanted Sexual Experiences in Women Consulting for Female Sexual Dysfunction According to Their Timing Across the Life Span.

BACKGROUND: Comparative data on the psychopathologic and sexual correlates of unwanted sexual experiences (USEs) occurring during childhood, adolescence, or adult life are lacking. AIM: To investigate the prevalence of USEs in a setting of female sexual dysfunction (FSD) and to examine whether they are associated with different psychosexual parameters depending on the timing of occurrence. METHODS: A consecutive series of 200 heterosexual women attending our clinic for FSD was consecutively recruited. MAIN OUTCOME MEASURE: Patients underwent a structured interview and completed the Female Sexual Function Index, the Middlesex Hospital Questionnaire, the Female Sexual Distress Scale-Revised, the Body Uneasiness Test, and the Childhood Experience of Care and Abuse questionnaire. USEs were classified as occurring in adult life (≥17), adolescence (<17 and ≥14), or childhood (<14 years). RESULTS: 47 women (23.5%) reported USEs, occurring in childhood, adolescence, and adult life in 38.3% (n = 18), 31.9% (n = 15), and 29.8% (n = 14) of cases, respectively. We observed an association between history of lifetime USEs and indexes of psychopathology, specifically diagnosis of psychiatric diseases, use of psychiatric medications, and anxiety symptoms (Middlesex Hospital Questionnaire free-floating anxiety score). USEs were associated with lower orgasm ability (Female Sexual Function Index orgasm domain), higher sexually related distress levels (Female Sexual Distress Scale-Revised total score), and higher body image concerns (Body Uneasiness Test) including depersonalization symptoms. Notably, women exposed to USEs in adolescence reported a stronger impairment of arousal, orgasm, and satisfaction domains and higher sexual distress when compared to women without a history of USEs or reporting USEs in childhood. Women exposed to USEs in childhood exhibited higher body image concerns and depersonalization symptoms when compared to those not reporting USEs. CLINICAL IMPLICATIONS: USEs should be investigated in women consulting for FSD because patients who had USEs may require unique strategies to optimize the diagnostic and therapeutic work-up of their sexual symptoms. STRENGTH & LIMITATIONS: Our main contribution is that we addressed the different impacts of USEs depending on their timing across the life span. However, the cross-sectional nature of the study does not allow determination of the cause-and-effect nature of the associations, and the selectivity of the sample (women consulting for FSD) limits the generalizability of the results. CONCLUSION: The negative outcomes of USEs vary according to their timing of occurrence: adolescence appears as the most sensitive temporal window for USEs to exert their deleterious effects on female sexuality, whereas childhood USEs are more tightly related to a severe body uneasiness in adult life.
