Deliriumalso known as acute confusional stateis an organically caused decline from a previous baseline mental functioning that develops over a short period of time, typically hours to days. It may also involve other neurological deficits, such as psychomotor disturbances e.

Delirium is caused by an acute organic processwhich is a physically identifiable structural, functional, or chemical problem in the brain that may arise from a disease process outside the brain that nonetheless affects the brain. It may result from an underlying disease process e. Delirium may be difficult to il delirium tremens comesser trattato without the proper establishment of a person's usual mental function.

Without careful assessment and history, delirium can easily be confused with a number of psychiatric disorders or chronic organic brain syndromes because of many overlapping signs and symptoms in common with dementiadepressionpsychosisetc. Treatment of delirium requires treating the underlying cause and multi-faceted interventions are thought to be most effective. Antipsychotics il delirium tremens comesser trattato not supported for the treatment or prevention of delirium among those who are in hospital.

In common usage, delirium is often used to refer to drowsiness, disorientation, and hallucination. Several medical definitions of delirium exist including those in the DSM and ICDbut the core features remain the same. Delirium arises through the interaction of a number of predisposing and precipitating factors.

Conversely, delirium may only result in healthy individuals if they suffer serious or multiple precipitating factors. The most important predisposing factors are: [15]. Any acute factors that affect neurotransmitter, neuroendocrine, or neuroinflammatory pathways can precipitate an episode of delirium in a vulnerable brain.

The lack of animal models that are relevant to delirium has left many key questions in delirium pathophysiology unanswered. Earliest rodent models of delirium used atropine a muscarinic acetylcholine receptor blocker to induce cognitive and electroencephalography EEG changes similar to delirium, and other anticholinergic drugs, such as biperiden and hyoscinehave produced similar effects. Along with clinical studies using various drugs with anticholinergic activity, these models have contributed to a "cholinergic deficiency hypothesis" of delirium.

Profound systemic inflammation occurring during sepsis is also known to cause delirium often termed sepsis-associated encephalopathy. Studies of cerebrospinal fluid CSF in delirium are difficult to perform. Apart from the general difficulty of recruiting participants who are often unable to give consent, the inherently invasive nature of CSF sampling makes such research particularly challenging.

Il delirium tremens comesser trattato, a few studies have exploited the opportunity to sample CSF from persons undergoing spinal anesthesia for elective or emergency surgery. A systematic review showed that, broadly, delirium may be associated with neurotransmitter imbalance namely serotonin and dopamine signalingreversible fall in somatostatin, and il delirium tremens comesser trattato cortisol.

Although neuroimaging offers a non-invasive way to understand delirium, it has been challenge to establish correlates with delirium. Many attempts to image people with concurrent delirium are unsuccessful. In addition, there is a more general bias il delirium tremens comesser trattato younger and fitter participants amenable to scanning, especially if using intensive techniques such as MRI. Despite similar heterogeneity in study design as described in an older analysis, [25] a systematic review summarizes evidence of associated white matter disease including cerebral atrophyventricular enlargement, and white matter lesionsabnormal changes in diffusion MRI characteristics il delirium tremens comesser trattato brain metabolites reflecting microscopic tissue damage and non-neuronal nervous cell activityand abnormal connectivity between different functional regions of the brain consistent with interruptions in executive function, sensory processing, attention, emotional regulation, memory, and orientation as seen in delirium.

Electroencephalography EEG allows for continuous capture of global brain function and brain connectivity, and is useful in understanding real-time physiologic changes during delirium.

Only a handful of studies exist where there has been an attempt to correlate delirium with pathological findings at autopsy. One research study has been reported on 7 patients who died during ICU admission. A case-control study showed that 9 delirium cases showed higher expression of HLA-DR and CD68 markers of microglial activationIL-6 cytokines pro-inflammatory and anti-inflammatory activities and GFAP marker of astrocyte activity than age-matched controls; this supports a neuroinflammatory cause to delirium, but the conclusions are limited by methodological issues.

A retrospective study correlating autopsy data with MMSE scores from brain donors found that delirium combined with a pathological process of dementia accelerated MMSE score decline more than either individual process. A diagnosis of delirium cannot be made without a previous assessment of the patient's baseline level of cognitive function.

Multiple guidelines recommend that delirium should il delirium tremens comesser trattato diagnosed when it presents to healthcare services. Much evidence reveal, however, that il delirium tremens comesser trattato is il delirium tremens comesser trattato under-diagnosed. Many such tools have been published. They differ in duration, complexity, need for training, etc.

In the ICU, international guidelines recommend that every patient gets checked for delirium every day usually twice or more a il delirium tremens comesser trattato using a validated clinical tool.

More emphasis is placed on regular screening over the choice of tool used. This, coupled with proper documentation and informed awareness by the healthcare team, can affect clinical outcomes.

Other processes and syndromes that cause cognitive dysfunction resembling delirium include the following: [ citation needed ]. Delirium may be prevented by systematically addressing the common il delirium tremens comesser trattato factors, such as constipation, dehydration, low oxygen levels, immobility, il delirium tremens comesser trattato the simultaneous use of multiple or problematic il delirium tremens comesser trattato.

Melatonin and other pharmacological agents have been studied for prevention of postoperative delirium, but evidence is not clear. The authors of this review were uncertain whether maintenance of anaesthesia with propofol-based total intravenous anaesthesia TIVA or with inhalational agents can affect incidences of postoperative delirium. Treatment of delirium involves two main strategies: 1. Such interventions are the first measures in managing active delirium and has many overlaps with delirium preventative strategies, including optimizing the hospital environment by reducing ambient noise, providing proper lighting for the time of day, minimizing room changes and restraint use.

Family, friends, and other caregivers can offer frequent reassurance, tactile and verbal orientation, cognitive stimulation e. Another approached called the "T-A-DA tolerate, anticipate, don't agitate method" can be an effective management technique for older people with delirium, where abnormal patient behaviors including hallucinations and delusions are tolerated and unchallenged, as long as caregiver and patient safety is not threatened.

Low-dose haloperidol when used short term one week or less is the most studied and standard drug il delirium tremens comesser trattato delirium. Benzodiazepines themselves can trigger or worsen delirium, and there is no reliable evidence for use in non-alcohol-related delirium.

The il delirium tremens comesser trattato trazodone is occasionally used in the treatment of delirium, but it carries a risk of over-sedation, and its use has not been well studied.

There is substantial evidence that delirium results in long-term poor outcomes in older persons admitted to hospital. In older persons admitted to hospital, individuals experiencing delirium are twice as likely to die than those who do not meta-analysis of 12 studies. Institutionalization was also twice as likely after an admission with delirium meta-analysis of 7 studies. The association between delirium and dementia is complex. Il delirium tremens comesser trattato systematic review estimated a fold increase in dementia after delirium meta-analysis of 2 studies.

In prospective studies, people hospitalised from any cause appear to be at greater risk of dementia [63] and faster trajectories of cognitive decline, [63] [64] but these studies did not specifically look at delirium. In the only population-based prospective study of delirium, older persons had an eight-fold increase in dementia and faster cognitive decline. Another way of looking at dementia, however, is not strictly based on the decline component, but il delirium tremens comesser trattato the degree il delirium tremens comesser trattato memory and executive function problems.

The causes of delirium in such patients depend on the underlying illnesses, new problems like sepsis and low oxygen levels, and the sedative and pain medicines that are nearly universally given to all ICU patients. Outside the ICU, on hospital wards and in nursing homes, the problem of delirium is also a very important medical problem, especially for older patients.

Delirium is one of the oldest forms of mental disorder known in medical history. English medical writer Philip Barrow noted in that if delirium resolves, it may be followed by a "loss of memory and reasoning power. Simsp. The American Delirium Society is a community of professionals dedicated to improving delirium care.
