A focused and inexpensive educational programme can decrease the prevalence of delirium among older inpatients.

The trial included a control group and two intervention groups, both of which received exercise programs created specifically for patients with FM. In clinical practice, we suggest including both modalities in an exercise therapy program for FM.

We investigated whether previously reported differences between Alzheimer's disease and dementia with Lewy bodies (DLB) in resting occipital activity lead to activation differences within functionally specialized visual cortical areas and deactivation differences in the default network. Patients with Alzheimer's disease (n = 10; 5 male), DLB (n = 9; 4 male) and controls (n = 13; 5 male) performed three functional MRI (fMRI) scanning experiments involving visual colour, face or motion stimuli. Reaction time or accuracy in DLB and Alzheimer's disease differed significantly from controls but not between patient groups, with the exception of accuracy in the face task (DLB < Alzheimer's disease; P = 0.038). The most significant fMRI activations in the pooled data set were in left V4alpha for the colour task (Talairach coordinate: -30, -52, -24; P = 0.002 corrected), the right fusiform face area (FFA) for the face task (34, -48, -22; P = 0.005 corrected) and right intra-parietal sulcus (30, -66, 42; P = 0.003 corrected) for the motion task, with additional activity in right V5 (48, -64, 0; P = 0.015 corrected). Each task was associated with decreases in activity within the default network with prominent deactivation foci bilaterally in the posterior cingulate gyrus (+/-8, -48, 26; left P < 0.001; right P < 0.001 corrected) and medial frontal cortex (+/-18, 42, 32; left P < 0.001; right P < 0.001 corrected). Comparing patterns of task-related activity across groups, DLB patients showed more activation than Alzheimer patients within the superior temporal sulcus (STS) for the motion task (right STS: 44, 0, -20; P = 0.004 corrected; left STS: -40, -4, -26; P = 0.07 corrected). This difference could not be attributed to task performance, cognitive score or age [analysis of covariance (ANCOVA)F (2, 18) = 8.44, P = 0.003]. Within regions of interest, group activation differences were found for the face task (Alzheimer's disease > DLB P = 0.05; Alzheimer's disease > controls P = 0.14) and the motion task (DLB < Alzheimer's disease P = 0.031 and DLB < control P = 0.048). However, these differences could be explained by behavioural performance, failing to reach significance in the ANCOVA analysis. In the default network, group deactivation differences between controls and both patient groups were found for the colour and motion task (colour: control < Alzheimer's disease P = 0.02; control < DLB P = 0.019; motion: control < Alzheimer's disease P = 0.118; control < DLB P = 0.118) but could be accounted for by behavioural performance. The results suggest that cognitive fMRI can be used to detect both performance-dependent and performance-independent differences between Alzheimer's disease and DLB, reflecting the distribution of functional pathology in the two conditions.

Previous studies exploring the prevalence of depression among South Asians reported inconsistent findings. Research artefacts due to sampling bias, measurements errors and a failure to include ethnographic methods may all explain this. We estimated the prevalence of depression, and variations of prevalence with culture, cultural adaptation, somatic symptoms and physical disability in a cross-sectional primary care survey of Punjabi and English attendees. We included a culture specific screening instrument, culturally adapted the instruments and offered bilingual interviews. We found that, compared with their English counterparts, depressive diagnoses were more common among Punjabis, Punjabi women, Punjabis with physical complaints and, contrary to expectation, even Punjabis with low scores for somatic symptoms.
