Delirium is an acute and relatively sudden (developing over hours to days) decline in attention-focus, perception, and cognition Cognition is the scientific term for "the process of thought". Its usage varies in different ways in accord with different disciplines: For example, in psychology and cognitive science it refers to an information processing view of an individual's psychological functions. Other interpretations of the meaning of cognition link it to the.
Bickerstaff defines delirium as a state in which the patient appears out of touch with his surroundings and is spontaneously producing evidence of his confusion and disorientation by muttering, rambling, shouting, often offensively and continuously, with evidence of delusion and hallucination, and often with so much associated motor activity that physical exhaustion overcomes him.
In medical usage it is not synonymous with drowsiness, and may occur without it. Delirium is not the same as dementia Dementia is a serious cognitive disorder. It may be static, the result of a unique global brain injury or progressive, resulting in long-term decline in cognitive function due to damage or disease in the body beyond what might be expected from normal aging. Although dementia is far more common in the geriatric population, it may occur in any stage (the two entities have different diagnostic criteria), though it commonly occurs in demented patients.
Delirium may be of a hyperactive variety manifested by 'positive' symptoms of agitation or combativeness, or it may be of a hypoactive variety (often referred to as 'quiet' delirium) manifested by 'negative' symptoms such as inability to converse or focus attention or follow commands. While the common non-medical view of a delirious patient is one who is hallucinating, most people who are medically delirious do not have either hallucinations or delusions. Delirium is commonly associated with a disturbance of consciousness (e.g., reduced clarity of awareness of the environment). The change in cognition (memory deficit, disorientation, language disturbance) or the development of a perceptual disturbance, must be one that is not better accounted for by a pre-existing, established, or evolving dementia Dementia is a serious cognitive disorder. It may be static, the result of a unique global brain injury or progressive, resulting in long-term decline in cognitive function due to damage or disease in the body beyond what might be expected from normal aging. Although dementia is far more common in the geriatric population, it may occur in any stage. Usually the rapidly fluctuating time course of delirium is used to help in the latter distinction.[1]
Delirium itself is not a disease, but rather a clinical syndrome In medicine and psychology, the term syndrome refers to the association of several clinically recognizable features, signs , symptoms (reported by the patient), phenomena or characteristics that often occur together, so that the presence of one feature alerts the physician to the presence of the others. In recent decades the term has been used (a set of symptoms A symptom is a departure from normal function or feeling which is noticed by a patient, indicating the presence of disease or abnormality. A symptom is subjective, observed by the patient, and not measured), which result from an underlying disease or new problem with mentation. Like its components (inability to focus attention Attention is the cognitive process of selectively concentrating on one aspect of the environment while ignoring other things. Attention has also been referred to as the allocation of processing resources , confusion and various impairments in awareness and temporal and spatial orientation), delirium is simply the common symptomatic manifestation of early brain or mental dysfunction (for any reason).
Without careful assessment, delirium can easily be confused with a number of psychiatric disorders A mental disorder or mental illness is a psychological or behavioral pattern that occurs in an individual and is thought to cause distress or disability that is not expected as part of normal development or culture. The recognition and understanding of mental disorders has changed over time and across cultures. Definitions, assessments, and because many of the signs and symptoms A symptom is a departure from normal function or feeling which is noticed by a patient, indicating the presence of disease or abnormality. A symptom is subjective, observed by the patient, and not measured are conditions present in dementia Dementia is a serious cognitive disorder. It may be static, the result of a unique global brain injury or progressive, resulting in long-term decline in cognitive function due to damage or disease in the body beyond what might be expected from normal aging. Although dementia is far more common in the geriatric population, it may occur in any stage, depression Major depressive disorder is a mental disorder characterized by an all-encompassing low mood accompanied by low self-esteem, and loss of interest or pleasure in normally enjoyable activities. The term "major depressive disorder" was selected by the American Psychiatric Association to designate this symptom cluster as a mood disorder in, and psychosis Psychosis , with adjective psychotic, literally means abnormal condition of the mind, and is a generic psychiatric term for a mental state often described as involving a "loss of contact with reality". People suffering from psychosis are said to be psychotic.[2] Delirium is probably the single most common acute disorder affecting adults in general hospitals. It affects 10-20% of all hospitalized adults, and 30-40% of elderly hospitalized patients and up to 80% of ICU An intensive care unit , critical care unit (CCU), intensive therapy unit or intensive treatment unit (ITU) is a specialized department used in many countries' hospitals that provides intensive care medicine. Many hospitals also have designated intensive care areas for certain specialities of medicine, as dictated by the needs and available patients.[3]
Treatment of delirium requires treatment of the underlying causes. In some cases, temporary or palliative or symptomatic treatments are used to comfort patients or to allow better patient management (for example, a patient who, without understanding, is trying to pull out a ventilation tube that is required for survival).
Educational information is available for medical and non-medical persons with videos, management protocols, links to references, lectures, recent evidence from studies, implementation packets for hospitals, and even comments to families and loved ones for those witnessing someone going through a delirious episode.
