Delirium is a severe, acute neuropsychiatric syndrome that is highly prevalent in acute hospital populations. Delirium has noticeable effects on length of hospitalization, cost of care, mortality and morbidity. In addition to these well-established adverse consequences, there is increasing evidence linking delirium and a higher risk of long-term cognitive impairment (LTCI), including dementia. ⋯ We go on to discuss putative mechanisms and explanations. These include (1) delirium as a marker of chronic progressive pathology, but unrelated to any progression, (2) delirium as a consequence of acute brain damage which is also responsible for a 'single hit' or triggering of active processes causing LTCI, (3) delirium itself as a cause of LTCI, and (4) drug treatment of delirium or other conditions as a cause of LTCI. We conclude with suggestions for future research.

Delirium has been historically under studied and under appreciated despite its high frequency and profound impact upon outcomes. This reflects failures at all levels from awareness among frontline staff, ownership by specialist researchers, funding from research bodies, and policy making by senior management and politicians. ⋯ Delirium as an entity has been victim to its unique position at the mind-body interface and occurrence across multiple disciplines such that no one specialty recognizes delirium as its primary responsibility. It is time for the healthcare community to respond to the challenge of delirium.

There is evidence that intra- and inter-hemispheric white matter communication, mainly fronto-limbic and callosal connectivity, is impaired in bipolar disorder as reported in several magnetic resonance (MR) diffusion imaging studies. In this review we will discuss diffusion imaging studies that examined white matter integrity in patients with bipolar disorder, trying to outline future research strategies.

Black and ethnic minorities show different pathways to care services and different routes out of care. These often involve non-statutory sector services. In order to improve access to services, and to develop appropriate and effective interventions, many innovations are described but the knowledge about how to improve pathways to recovery has not been synthesized. ⋯ The key components of effective pathway interventions include specialist services for ethnic minority groups, collaboration between sectors, facilitating referral routes between services, outreach and facilitating access into care, and supporting access to rehabilitation and moving out of care. Services that support collaboration, referral between services, and improve access seem effective, but warrant further evaluation. Innovative services must ensure that their evaluation frameworks meet minimum quality standards if the knowledge gained from the service is to be generalized, and if it is to inform policy.
