Persistent postural perceptual dizziness (PPPD) is the most common vestibular syndrome in middle-aged patients. Multisensory maladjustment involving alterations of sensory response pattern including vestibular, visual and motion stimuli is thought to be a key pathophysiological correlate of this disorder. ⋯ In patients with PPPD areas involved in multisensory vestibular processing show gray matter volume decrease. These brain regions resemble those previously described for other vestibular disorders. Longer duration of disease leads to a more pronounced gray matter alteration, which might represent maladaptive mechanisms within the course of disease.

Current models assume somatoform pain disorder (SPD) to be the result of a complex interaction between bio- and psychosocial factors, but the etiology is still not well understood. This study aimed to investigate the distribution of attachment style and the frequency of traumatic life events, especially childhood adversities, in patients with SPD compared to healthy controls. ⋯ The high predictive value of insecure attachment style and cumulative traumatic events emphasize their importance as risk factors of SPD.

Sedation is a core concept in the intensive care setting, however, the impact of sedation on delirium has not yet been studied to date. ⋯ Drowsiness increased the odds for developing delirium eightfold and caused more severe delirium, which was characterized by sleep-wake cycle and language abnormalities. Further, drowsiness by itself caused attentional impairment and language abnormalities, thus, with its disturbance in consciousness was subthreshold for delirium.
