Despite the growing prevalence of dementia, few models of training for health professional students on this topic have been formally evaluated or widely disseminated. The Dementia Friends (DF) initiative is part of a global movement to improve the way people think, act, and talk about dementia. The impact of these sessions on the dementia-related knowledge and attitudes of health professional trainees has not been adequately assessed. Health professional students (medicine n = 70, physical therapy n = 30, pharmacy n = 28) participated in one-hour DF information sessions, offered in-person or via videoconference. The Dementia Attitudes Scale (DAS), a validated 20-item questionnaire, was administered before and after each session. Pre- and post-session DAS scores were compared using a paired t-test. Students' dementia-friendly action plans were analyzed qualitatively. Of 128 students, 102 (80%) completed both the pre- and post-DAS. The mean DAS score increased significantly from 105.8 (12.3) to 120.8 (10.5) following the DF sessions (p <.001). Students' dementia-friendly action plans included improving communication, promoting quality of life, and learning more about dementia. The DF information session model significantly increased the knowledge and positive attitudes of health professional students toward those living with dementia. Further use and study of this model is appropriate. [ABSTRACT FROM AUTHOR]

In our article we considered the nature and the functional anatomy of “urges-for-action,” both in the context of everyday behaviors such as yawning, swallowing, and micturition, and in relation to clinical disorders in which the urge-for-action is considered pathological (e.g., Tourette syndrome), and we argued for a key role for the insular and cingulate cortices in experiencing the urge-for-action. Here we seek to address some of the key points raised within several of the interesting commentaries on, and challenges to, our paper. [ABSTRACT FROM PUBLISHER]

Several common neuropsychiatric disorders (e.g., obsessive-compulsive disorder, Tourette syndrome (TS), autistic spectrum disorder) are associated with unpleasant bodily sensations that are perceived as an urge for action. Similarly, many of our everyday behaviors are also characterized by bodily sensations that we experience as urges for action. Where do these urges originate? In this paper, we consider the nature and the functional anatomy of “urges-for-action,” both in the context of everyday behaviors such as yawning, swallowing, and micturition, and in relation to clinical disorders in which the urge-for-action is considered pathological and substantially interferes with activities of daily living (e.g., TS). We review previous frameworks for thinking about behavioral urges and demonstrate that there is considerable overlap between the functional anatomy of urges associated with everyday behaviors such as swallowing, yawning, and micturition, and those urges associated with the generation of tics in TS. Specifically, we show that the limbic sensory and motor regions––insula and mid-cingulate cortex––are common to all of these behaviors, and we argue that this “motivation-for-action” network should be considered distinct from an “intentional action” network, associated with regions of premotor and parietal cortex, which may be responsible for the perception of “willed intention” during the execution of goal-directed actions.

The intention to execute a movement can modulate our perception of sensory events; however, theoretical accounts of these effects, and also empirical data, are often contradictory. We investigated how perception of a somatosensory stimulus differed according to whether it was delivered to a limb being prepared for movement or to a nonmoving limb. Our results demonstrate that individuals perceive a somatosensory stimulus delivered to the “moving” limb as occurring significantly later than when an identical stimulus is delivered to a “nonmoving” limb. Furthermore, human brain imaging (fMRI) analyses demonstrate that this modulation is accompanied by a significant decrease in BOLD signal in the right parietal operculum (SII) for stimuli delivered to the moving limb. These results indicate that during movement preparation a network of premotor brain areas may facilitate movement execution by attenuating the processing of behaviorally irrelevant signals within higher-order secondary somatosensory (SII) areas.
