A cognitive disorder characterized by impairment in consciousness and attention and changes in cognition (e.g., memory deficit, disorientation, language or perceptual disturbance). The following types of delirium are recognized by dsm-iv-tr: delirium due to a general medical condition, substance-induced delirium (in intoxication and withdrawal states), delirium due to multiple etiologies, and delirium not otherwise specified.
An acute organic mental disorder characterized by confusion and altered, possibly fluctuating, consciousness due to an alteration of cerebral metabolism; it may include delusions, illusions, and/or hallucinations. The condition is reversible if the underlying cause can be identified and treated. It may, however, progress to dementia or death. Often emotional labilify, typically appearing as anxiety and agitation, is present. Contrast with dementia.
Mental state characterised by reduced ability to maintain attention to external stimuli and disorganised thinking.
A condition of extreme mental and usually motor excitement is marked by a rapid succession of confused and unconnected ideas, often illusions, and hallucinations.
A mental state in which someone is confused, excited and restless and has hallucinations.
A state of mental illness usually found in long-term alcoholics who attempt to give up alcohol consumption. It includes hallucinations about insects, trembling and excitement.
confused, turbulent mental state, often including hallucinations, delusions, lability (emotional swings), and anxiety, generally an acute reaction in cases of organic mental disorder, as may be caused by infection, metabolic disorders, head injury, or trauma. Delirium is usually reversible once the underlying condition is treated. In cases of alcohol abuse, the state caused by withdrawal is often called delirium tremens (DTs).
State, usually brief, of incoherent excitement, confused speech, restlessness, and hallucinations. It may occur in high fever, ingestion of certain toxic substances and drugs, nutritional deficiencies, endocrine imbalance, or severe stress (e.g., postoperative) or mental illness. Treatment includes bed rest, quiet, the use of drugs to quiet the patient, and treatment of the underlying cause.
Acute confusion, disorientation, and agitation due to toxic levels of body chemicals, drugs, or alcohol in the blood that affect the brain.
A state of mental confusion that develops over a few hours or days and tends to fluctuate, often rapidly. Delirium involves changes in consciousness, such as reduced awareness of the person’s surroundings, a loss of attention or concentration, impaired memory, disorientation to time or place, and impaired use of language (such as difficulty naming objects).
An acute disorder of the mental processes accompanying organic brain disease. It may be manifested by illusions, disorientation, hallucinations, or extreme excitement and occurs in metabolic disorders, intoxication, deficiency diseases, and infections.
A condition of altered consciousness in which there is disorientation (as in a confusional state), incoherent talk and restlessness but with hallucination, illusions or delusions also present.
An acute, reversible state of disorientation and confusion. Delirium is marked by disorientation without drowsiness; hallucinations or delusions; difficulty in focusing attention; inability to rest or sleep; and emotional, physical, and autonomic overactivity.
Disordered state of mind with great excitement and often hallucinations.
A state of consciousness disturbance characterized by confusion, lack of focus, delusions, hallucinations, and restlessness. This condition differentiates itself from dementia by its abrupt onset and fluctuating intensity of symptoms.
Delirium is a condition characterized by a state of acute mental confusion, often triggered by physical illness. The symptoms can vary depending on individual personality, environmental factors, and the severity of the underlying illness. Common manifestations may include difficulty comprehending events, memory impairment, physical restlessness, mood swings, hallucinations, and feelings of panic. Contributing factors to delirium often involve fever and disruptions in the body’s chemistry.
Delirium tends to affect children and older individuals with greater susceptibility, especially in cases of infection, post-surgical recovery, or when there is an underlying brain disturbance such as dementia in elderly individuals. The use of certain drugs, exposure to toxins, and alcohol consumption are common factors that can precipitate the onset of delirium.
A state of mental confusion that includes hallucinations, delusions, restlessness, and a lack of orientation.
