Confusion (from Latin confusĭo, -ōnis, from confundere: "to pour together;" "to mingle together;" "to confuse") is the state of being bewildered or unclear in one’s mind about something.
Medical term [ edit ]
The term, "acute mental confusion"
is often used interchangeably with [1 ] delirium in the [2 ] and the International Statistical Classification of Diseases and Related Health Problems publications to describe the Medical Subject Headings pathology. These refer to the loss of orientation, or the ability to place oneself correctly in the world by time, location; and personal identity. Mental confusion is sometimes accompanied by disordered consciousness (the loss of linear thinking) and memory loss (the ability to correctly recall previous events or learn new material). [3 ]
Mental confusion may result from drug side effects or from a relatively sudden brain dysfunction. Acute confusion is often called
delirium (or "acute confusional state"), although delirium often includes a much broader array of disorders than simple confusion. These disorders include the inability to focus attention; various impairments in awareness; and temporal or spatial dis-orientation. Mental confusion can result from chronic organic brain pathologies, such as [4 ] dementia, as well.
Differential diagnosis [ edit ]
The most common causes of drug induced acute confusion are
dopaminergic drugs (used for the treatment of Parkinson's disease), diuretics, tricyclic or tetracyclic antidepressants and benzodiazepines. The elderly, and especially those with pre-existing dementia, are most at risk for drug induced acute confusional states. New research is finding a link between [5 ] Vitamin D deficiency and cognitive impairment (which includes 'foggy brain'). [6 ]
