Objective: Many studies have explored sense of self in individuals with autism spectrum disorder (ASD); however, few have reported on their experience of “disembodiment.” This study aimed to investigate the differences in brain activity between patients with ASD and neurotypicals (NTs) under conditions causing disembodiment and to examine the correlation between their interoceptive abilities and disembodiment-related brain activity. Methods: 18 Participants with ASD and 21 NTs completed psychological evaluations, interoceptive abilities measurement, and functional magnetic resonance imaging (fMRI). The fMRI images were taken while the participants performed tasks involving ball-throwing animations. The task focused on either self-agency related to ball-throwing (Agency Task) or the spatial location of a ball (Location Task). The animations were presented from constantly changing perspective (Changing View) or fixed perspective (Fixed View). The disembodiment-related condition was the interaction between the Agency Task and Changing View. Results: Participants with ASD exhibited higher activation than NTs in regions near the left parieto-temporo-occipital junction, left precuneus, left hippocampus, and other brain areas. Furthermore, interoceptive accuracy was negatively correlated with the activity of the left superior parietal and posterior midcingulate areas, whereas interoceptive trait prediction error was positively correlated with the activity of the left hippocampus, mid-temporal area, and left posterior cingulate area in participants with ASD. Conclusion These results suggest that disembodiment-related brain activation might be easily manifested by the interaction between perspective-shifting and the experience of agency, and that interoceptive abilities might be related to disembodiment-related brain activation in individuals with ASD.

Although histone deacetylase 6 (HDAC6) is considered a therapeutic target for Alzheimer’s disease (AD), its role in cholinergic dysfunction in AD patients remains unclear. This study investigated the effects of (E)-3-(2-(4-fluorostyryl)thiazol-4-yl)-N-hydroxypropanamide (4-FHA), a new synthetic HDAC6 inhibitor, on cognitive and memory impairments in a scopolamine-induced-AD mouse model. Behaviorally, 4-FHA improved scopolamine-induced memory impairments in the Y-maze, passive avoidance, and Morris water maze tests. In addition, 4-FHA ameliorated scopolamine-induced cognitive impairments in the novel object recognition and place recognition tests. Furthermore, 4-FHA increased acetylation of α-tubulin (a major HDAC6 substrate); the expression of BDNF; and the phosphorylation of ERK 1/2, CREB, and ChAT in the hippocampus of scopolamine-treated mice. In summary, according to our data 4-FHA, an HDAC6 inhibitor, improved the cognitive and memory deficits of the AD mouse model by normalizing BDNF signaling and synaptic transmission, suggesting that 4-FHA might be a potential therapeutic candidate for AD.

Purpose: This study aimed to evaluate the effects of an intervention combining warm therapy (via a thermoelectric-element tourniquet) and a distraction-based approach (via an augmented reality-based app known as TWINKLE) on pain, stress, and satisfaction during intravenous catheterization in adults. Methods: A randomized controlled trial was conducted in South Korea with 93 healthy adults who were randomly assigned to one of three groups: the experimental group (TWINKLE app with warm therapy), the comparison group (warm therapy only), and the control group (no treatment). Participants’ pain, stress, and satisfaction, as well as practitioner satisfaction, were measured after the intervention. Results: Pain scores differed significantly among the three groups (F = 5.68, p = .005), with the experimental group showing significantly lower scores than the control group (p = .003). Stress levels were also significantly lower in the experimental group than in the other groups (F = 9.42, p < .001). Participant satisfaction was highest in the experimental group (F = 17.65, p < .001), while nurse satisfaction was significantly higher in the comparison group than in the experimental and control groups (F = 67.91, p < .001), suggesting that the additional distraction intervention may have increased nurses’ workload. Conclusion Combining digital distraction with warm therapy using a thermoelectric-element tourniquet effectively reduces pain and stress while improving patient satisfaction during intravenous catheterization. Further research is needed to optimize this approach, with a particular focus on targeting digital distraction interventions to patients with higher levels of procedural anxiety and finding ways to minimize practitioner workload.
