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<unk>  organic brain pathologies, such as dementia, as well.

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 vitamin D deficiency and cognitive impairment (which includes "foggy brain").
