Abstract
BACKGROUND Catastrophic thinking among patients with chronic pain impairs their quality of life and increases anxiety levels. Further, severe pain causes high emotional brain sensitivity and unpleasant feelings. However, the effects of emotional changes on catastrophic thinking in patients with chronic pain remain unclear. AIMS We hypothesised that emotional brain activity during mild pain stimuli would affect catastrophic thinking in these patients. We aimed to examine the relationship between unpleasant emotional brain activation and catastrophic thinking due to pain stimuli in patients with chronic pain. DESIGN This was a prospective observational study. PARTICIPANTS We included patients with chronic pain and healthy individuals. METHODS The impact of emotional brain activity on catastrophic thinking was evaluated, specifically, the skin conductance response and oxygenated haemoglobin levels using near-infrared spectroscopy. After receiving three different pain stimuli, the participants were evaluated using the Numeric Rating Scale, Pain Catastrophising Scale, and McGill Pain Questionnaire. RESULTS There were 28 patients in the chronic pain group and 33 patients in the healthy group. There was no between-group difference in oxygenated haemoglobin levels during pain stimulation. The chronic pain group showed a higher Pain Catastrophising Scale score and skin conductance response than the healthy group (p < .05). In the chronic pain group, oxygenated haemoglobin levels after pain stimuli were significantly associated with the Pain Catastrophising Scale score and skin conductance response (p < .05). CONCLUSIONS Brain activity of unpleasant emotions may influence catastrophic thinking in patients with chronic pain.

Abstract
PURPOSE OF REVIEW The purpose of the following paper is to review recent literature trends and findings in hoarding disorder (HD). Our goal is to highlight recent research on etiology, associated features, and empirically based treatments. RECENT FINDINGS Recent literature has added support for cognitive differences as a risk factor for HD; however, there is evidence that individuals with HD may overestimate their level of cognitive impairment. Several associated features have been highlighted in recent studies, including emotion regulation, intolerance of uncertainty and distress intolerance, and attachment. Finally, several psychotherapeutic treatments for hoarding have been recently validated, including group-based therapy and treatments using the cognitive-behavioral model. Although recent research demonstrates that hoarding can be effectively treated with available psychotherapeutic modalities, the effectiveness of current treatments is not as robust as that for other psychiatric disorders and more work is needed in treatment precision.

Discarding personal possessions increases psychophysiological activation in patients with hoarding disorder. Psychiatry Res 2019; 272:499-506. [PMID: 30616116 DOI: 10.1016/j.psychres.2018.12.163] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Revised: 12/11/2018] [Accepted: 12/29/2018] [Indexed: 11/23/2022]
Abstract
Difficulty discarding is the core behavioral symptom of hoarding disorder (HD). Patients with HD report greater subjective distress when discarding their own possessions as compared to others' possessions. To date, no prior studies have examined psychophysiological activation, an objective measure of anxious arousal, during discarding among individuals with HD. The current study assessed psychophysiological responses during a baseline resting period and two discarding tasks, one involving personal possessions and the other involving matched control ("experimenter-owned") items in 52 patients with a primary diagnosis of HD. Results showed that, compared to discarding control items, discarding personal possessions increased skin conductance and heart rate and decreased end tidal carbon dioxide. There were no differences in heart rate variability, respiratory sinus arrhythmia, and respiration rate between the two discarding tasks. Despite the fact that discarding increased psychophysiological arousal, self-reported HD symptoms (including difficulty discarding) failed to predict psychophysiological responses during the discarding tasks. The findings suggest that there may be discordance between objective and subjective measures of hoarding-related distress, and are discussed in terms of incorporating psychophysiological measures into the assessment and treatment of HD.
