DELIRIUM Introduction Delirium is from Latin and literally means the individual is not at the top of his/her form and travelling at a lower level than normal [de – (off, away from) + lira (a ridge between ploughed furrows)]. Delirium can be an outcome of a general medical conditions, head injury and drug intoxication or withdrawal. It may be the result of the dysfunction of various bodily organs such as kidneys and liver, but it may also be the result of primary pathological processes in the brain. Hospitalized patients > 65 years who experience delirium (compared to those who do not) are at greater risk of mortality (p<. It is a distressing (to patients, family and staff) and financially costly. Delirium is seen more commonly on medical and surgical wards than psychiatric wards. It complicates the hospital stays of 20% of the people over the age of 65 years, and is found in up to 87% of older patients in intensive care wards (Pisani et al, 2003). Disturbance of attention (reduced ability to focus, sustain, or shift attention). Develops over a short time (hours or a few days) – a change from baseline attention and awareness, fluctuates in severity in the course of a day. An additional disturbance in cognition (such as memory deficit, disorientation, language disturbance). Sub-types of delirium Three clinical subtypes of delirium, based on arousal and psychomotor behaviour are described (Trezepacz et al, 1999) 1. Hyperactive (hyperaroused, hyperalert, or agitated) 2. Hypoactive (hypoaroused, hypoalert, or lethargic) 3. Mixed (alternating features of hyperactive and hypoactive types) Pridmore S. Last modified: January, 2018 2 Hyperactive symptoms Hypoactive symptoms Hypervigilance Unawareness Restlessness Decreased alertness Fast or loud speech Lethargy Irritability Slowed movements Combativeness Staring Impatience Apathy Swearing Singing Laughing Uncooperativeness Euphoria Anger Wandering Easy startling Fast motor responses Distractibility Tangentiality Nightmares Persistent thoughts While the “classic” presentation of delirium is considered to be the wildly agitated patient, the hyperactive type represents only about 25% of cases. Over half all delirious patients have the hypoactive “quite” type. These people attract less attention and may pass undiagnosed - this (hypoactive) type has the poorer prognosis. Another “classic” feature is widely believed to be “sundowning”, by which is meant, the mental status deteriorates in the evening. Recent work, however, demonstrated that more symptoms were demonstrated in the morning (47%) than in the afternoon, evening and night (37%). Confusion Assessment Method (CAM) CAM (Inouye et al, 1990) is a remarkable instrument – it is a brief structured assessment - with a sensitivity of 94%, a specificity of 89%, and moderate-to-high inter-rater reliability. The diagnosis of delirium by CAM requires the presence of features 1 and 2 and either 3 or 4. Does the (abnormal) behaviour fluctuate during the day, that is, does it tend to come and go or increase or decrease in severity? Inattention This feature is shown by a positive response to the following question: Does the patient have difficulty focusing attention such as are they easily distracted or do they have difficulty keeping track of what is being said?

In the visual modality, for example, the early which occurs because the initial S1 automatically activates C1 component (onset latency 50 to 60 msec) originates an inhibitory system that suppresses responsiveness to S2 (9, in retinotopically organized visual cortex (5) and varies in 10).
