RESUMEN

In this article, six analysts describe theory and practice in the time of COVID-19, examining the quality of après-coup in the way that the pandemic and its attendant crises trigger early memory and early experiences of helplessness. In the clinical events we see that the age of the patient, the circumstances and approach of the analyst, the novelty of the frame are all crucial determinants of clinical outcomes.

RESUMEN

OBJECTIVE: To evaluate relationships between psychiatric symptoms, acceptance, and migraine-related disability in a sample of people with migraine presenting at a tertiary care headache center. BACKGROUND: Migraine is a chronic disease that can be severely disabling. Despite a strong theoretical basis and evidence in other pain conditions, little is known about relationships between acceptance, psychiatric symptoms, and migraine-related disability. METHODS: Ninety patients with physician-diagnosed migraine completed surveys assessing demographics, headache symptoms, severe migraine-related disability (Migraine Disability Assessment Scale total score dichotomized at ≥ 21), depression (Patient Health Questionnaire-9) and anxiety symptoms (Generalized Anxiety Disorder-7), and acceptance (Chronic Pain Acceptance Questionnaire; subscales: Pain Willingness and Activity Engagement). RESULTS: Participants (77.8% white, non-Hispanic; 85.6% women; and 50.0% with a graduate level education) reported an average headache pain intensity of 6.7/10 (SD = 2.0). One-third (36.0%) reported chronic migraine, and half (51.5%) reported severe migraine-related disability. Lower acceptance was associated with severe migraine-related disability, t(54) = 4.13, P < .001. Higher activity engagement was associated with lower average headache pain intensity (r = -.30, P = .011). Higher acceptance was associated with lower levels of depression (r = -.48, P < .001) and anxiety symptoms (r = -.37, P = .003). Pain willingness and activity engagement serially mediated relationships between depression symptoms and severe migraine-related disability (indirect effect = 0.05, 95% CI = 0.01, 0.15), and between anxiety symptoms and severe migraine-related disability (indirect effect = 0.12, 95% CI = 0.02, 0.31). CONCLUSION: Results provided preliminary support for a theoretical pathway by which psychiatric symptoms may influence migraine-related disability, in part, through their relationships with pain willingness and activity engagement.

RESUMEN

BACKGROUND: Borderline personality disorder (BPD) and avoidant personality disorder (AvPD) are characterized by hyper-reactivity to negatively-perceived interpersonal cues, yet they differ in degree of affective instability. Recent work has begun to elucidate the neural (structural and functional) and cognitive-behavioral underpinnings of BPD, although some initial studies of brain structure have reached divergent conclusions. AvPD, however, has been almost unexamined in the cognitive neuroscience literature. METHODS: In the present study we investigated group differences among 29 BPD patients, 27 AvPD patients, and 29 healthy controls (HC) in structural brain volumes using voxel-based morphometry (VBM) in five anatomically-defined regions of interest: amygdala, hippocampus, medial prefrontal cortex (MPFC), dorsolateral prefrontal cortex (DLPFC), and anterior cingulate cortex (ACC). We also examined the relationship between individual differences in brain structure and self-reported anxiety and affective instability in each group. RESULTS: We observed reductions in MPFC and ACC volume in BPD relative to HC, with no significant difference among patient groups. No group differences in amygdala volume were found. However, BPD and AvPD patients each showed a positive relationship between right amygdala volume and state-related anxiety. By contrast, in HC there was an inverse relationship between MPFC volume and state and trait-related anxiety as well as between bilateral DLPFC volume and affective instability. LIMITATIONS: Current sample sizes did not permit examination of gender effects upon structure-symptom correlations. CONCLUSIONS: These results shed light on potentially protective, or compensatory, aspects of brain structure in these populations-namely, relatively reduced amygdala volume or relatively enhanced MPFC and DLPFC volume.

RESUMEN

BACKGROUND: Avoidant personality disorder is characterized by pervasive anxiety, fear of criticism, disapproval, and rejection, particularly in anticipation of exposure to social situations. An important but underexplored question concerns whether anxiety in avoidant patients is associated with an impaired ability to engage emotion regulatory strategies in anticipation of and during appraisal of negative social stimuli. METHODS: We examined the use of an adaptive emotion regulation strategy, cognitive reappraisal, in avoidant patients. In addition to assessing individual differences in state and trait anxiety levels, self-reported affect as well as measures of neural activity were compared between 17 avoidant patients and 21 healthy control participants both in anticipation of and during performance of a reappraisal task. RESULTS: Avoidant patients showed greater state and trait-related anxiety relative to healthy participants. In addition, relative to healthy participants, avoidant patients showed pronounced amygdala hyper-reactivity during reappraisal anticipation, and this hyper-reactivity effect was positively associated with increasing self-reported anxiety levels. LIMITATIONS: Our finding of exaggerated amygdala activity during reappraisal anticipation could reflect anxiety about the impending need to reappraise, anxiety about the certainty of an upcoming negative image, or anxiety relating to anticipated scrutiny of task responses by the experimenters. While we believe that all of these possibilities are consistent with the phenomenology of avoidant personality disorder, future research may clarify this ambiguity. CONCLUSIONS: These results suggest that amygdala reactivity in anticipation of receiving negative social information may represent a key component of the neural mechanisms underlying the heightened anxiety present in avoidant patients.

RESUMEN

OBJECTIVE: Extreme emotional reactivity is a defining feature of borderline personality disorder, yet the neural-behavioral mechanisms underlying this affective instability are poorly understood. One possible contributor is diminished ability to engage the mechanism of emotional habituation. The authors tested this hypothesis by examining behavioral and neural correlates of habituation in borderline patients, healthy comparison subjects, and a psychopathological comparison group of patients with avoidant personality disorder. METHOD: During fMRI scanning, borderline patients, healthy subjects, and avoidant personality disorder patients viewed novel and repeated pictures, providing valence ratings at each presentation. Statistical parametric maps of the contrasts of activation during repeated versus novel negative picture viewing were compared between groups. Psychophysiological interaction analysis was employed to examine functional connectivity differences between groups. RESULTS: Unlike healthy subjects, neither borderline nor avoidant personality disorder patients exhibited increased activity in the dorsal anterior cingulate cortex when viewing repeated versus novel pictures. This lack of an increase in dorsal anterior cingulate activity was associated with greater affective instability in borderline patients. In addition, borderline and avoidant patients exhibited smaller increases in insula-amygdala functional connectivity than healthy subjects and, unlike healthy subjects, did not show habituation in ratings of the emotional intensity of the images. Borderline patients differed from avoidant patients in insula-ventral anterior cingulate functional connectivity during habituation. CONCLUSIONS: Unlike healthy subjects, borderline patients fail to habituate to negative pictures, and they differ from both healthy subjects and avoidant patients in neural activity during habituation. A failure to effectively engage emotional habituation processes may contribute to affective instability in borderline patients.

RESUMEN

Behavioral habituation during repeated exposure to aversive stimuli is an adaptive process. However, the way in which changes in self-reported emotional experience are related to the neural mechanisms supporting habituation remains unclear. We probed these mechanisms by repeatedly presenting negative images to healthy adult participants and recording behavioral and neural responses using functional magnetic resonance imaging. We were particularly interested in investigating patterns of activity in insula, given its significant role in affective integration, and in amygdala, given its association with appraisal of aversive stimuli and its frequent coactivation with insula. We found significant habituation behaviorally along with decreases in amygdala, occipital cortex and ventral prefrontal cortex (PFC) activity with repeated presentation, whereas bilateral posterior insula, dorsolateral PFC and precuneus showed increased activation. Posterior insula activation during image presentation was correlated with greater negative affect ratings for novel presentations of negative images. Further, repeated negative image presentation was associated with increased functional connectivity between left posterior insula and amygdala, and increasing insula-amygdala functional connectivity was correlated with increasing behavioral habituation. These results suggest that habituation is subserved in part by insula-amygdala connectivity and involves a change in the activity of bottom-up affective networks.
